A Medical Researcher Pays for Doubting Industry Claim



Erdem Cantekin declared a war of ethics on the University of Pittsburgh Medical Center, he was an ambitious 42-year-old biomedical engineer with a future full of promise He was a tenured professor, he and his wife, who was pregnant, were preparing to buy their first house, and he was director of research at a respected institute at the university.

Professor Erdem Cantekin Fifteen years later, Dr. Cantekin is broke, his career is in shambles, and he is widely known in his field as a "troublemaking whistle-blower," as he puts it. He is deep in debt to his lawyers and unable to afford a car, let alone the house he and his wife had once chosen for themselves. When he walks around the Pittsburgh campus, people who recognize him avert their eyes.

"I don't have any life left in this town," Dr. Cantekin says. "I am in the gulag.

Erdem Cantekin

Dr. Cantekin might have been nothing more than a brief sideshow in the annals of medical research, except that he is self-righteously persistent, and more important, his cause is at the center of a $3 billion-a-year industry: antibiotics for children's ear infections. Dr. Cantekin believes that in 1986, a fellow researcher at Pittsburgh, Charles Bluestone, manipulated the results of a study on children's antibiotics to benefit drug companies whose grants and honoraria he had accepted.

"It was a fraudulent study," says Dr. Cantekin, who was Dr. Bluestone's co-investigator on the project. "This isn't a question of scientific interpretation. They made certain changes to make the drugs look better." Partly as a result of this compromised research, he argues, millions of children have been taking antibiotics unnecessarily, spawning a population of antibiotic-resistant "superbugs" that threaten everyone.

Dr. Bluestone, a widely respected pediatric ear specialist, believed antibiotics were useful for the condition called otitis media with effusion, which is an accumulation of fluid in the middle ear. Lawyers for Dr. Bluestone and officials of the University of Pittsburgh, citing continuing litigation, declined to comment for this article. But in legal documents, they have repeatedly denied any impropriety in the research. At the time, there were no university or government regulations regarding private funding for research. Dr. Bluestone's paper on his research was peer-reviewed and accepted for publication by the New England Journal of Medicine. Dr. Cantekin, university officials have maintained, was making his allegations out of "malice" because his point of view on the study had been overidden.

In the years since the two doctors split over their research, Dr. Cantekin's allegations against Dr. Bluestone have been weighed by three University of Pittsburgh committees, three panels of the National Institutes of Health, a congressional subcommittee, a federal district court and the U.S. Court of Appeals. The government, the university and Dr. Cantekin have spent thousands of hours and millions of dollars trying to sort out what happened in that Pittsburgh medical laboratory in the mid-1980s. And it isn't over yet: Dr. Cantekin has brought a whistle-blower lawsuit against his adversaries, and a trial looms.

Deadly Consequences

But as the dispute has moved slowly through these tribunals, medical science has gradually come to its own conclusions about antibiotics and ear infections --and they are in line with Dr. Cantekin's. Although more antibiotics are prescribed today for children's ear infections --and for longer periods of time --in the U.S. than anywhere in the world, several recent, independently financed studies have found that for the vast majority of ear infections, antibiotics are little more effective than no treatment at all. Worse, physicians are now seeing in their own practices the potentially deadly consequences of too many children taking too many antibiotics --drug-resistant strains of bacteria. In the past few years, some pediatricians have begun to prescribe shorter courses of antibiotics, or even to take a different tack entirely: so-called watchful waiting. If the infection doesn't clear up in a few days, then antibiotics are used.

This approach would have been anathema to the pediatricians of the 1960s and'70s, for whom antibiotics were a miracle drug. In the 1940s and '50s, it was unusual for a child to see a doctor for a simple earache --there was little that could be done for them, and they usually cleared up anyway. But the consequences of untreated ear infections were well-known and occasionally dire. Some children suffered mastoiditis, meningitis, hearing loss and even death. Doctors and researchers suspected that antibiotics could help prevent some of these catastrophes, but there was no scientific proof.

That was the issue Dr. Cantekin and his then-mentor, Dr. Bluestone, decided to tackle in the early 1980s. The two men had met in Boston several years earlier. Dr. Bluestone, a graduate of the University of Pittsburgh and its medical school, was fast making a name for himself in pediatric otolaryngology. He has written more than 300 articles on the subject, as well as serving on government advisory boards. Dr. Cantekin, who was born and raised in Turkey, where his father was a middle-class public servant, had come to the U.S. to study at the Carnegie Institute of Technology in Pittsburgh, where he received a doctorate in biomedical engineering. In 1973, he was introduced to Dr. Bluestone, who was then working at Boston City Hospital. Dr. Bluestone hired Dr. Cantekin to help design and carry out research on children's ear infections.

In 1976, Dr. Bluestone invited Dr. Cantekin to come to Pittsburgh with him to set up the new Otitis Media Research Center. A few years later, the two men designed a large, randomized, double-blinded clinical trial --the gold standard of biomedical research. Over five years, they would compare antibiotic treatment -- specifically, a generic drug called amoxicillin --with no treatment at all on ear infections. Their research received a hefty $17.4 million in grants from the National Institutes of Health.

The first sign of trouble between the two investigators came in 1984, about halfway through the trial. The Otitis Media Research Center, of which Dr. Bluestone was the overall director, was then grappling with an accumulated deficit of about $300,000. Dr. Bluestone wrote letters to three pharmaceutical companies that made antibiotics for children, asking if they were interested in having their products tested alongside amoxicillin.

Eventually, several companies, including Eli Lilly & Co., Ross Laboratories (now part of Abbot! Laboratories) and Beecham Group (now part of GlaxoSmithKline PLC), contributed about $3.4 million to support trials of antibiotics for ear infections. "If we didn't have the support of non-NIH funding, such as from pharmaceutical companies, we would not be able to complete our clinical trials," Dr. Bluestone said later in a letter to the NIH. In addition, between 1983 and 1988, Dr. Bluestone received $262,000 in honoraria and travel expenses from pharmaceutical companies whose drugs he was testing.

After adding new sponsors, Dr. Bluestone made some changes to the original study design. Looking at interim data, he concluded that amoxicillin was effective, compared with a placebo, and he created new arms of the study to compare two "boutique" antibiotics, Lilly's Ceclor and Ross's Pediazole, to amoxicillin. The newer antibiotics can cost between $30 and $70 for a course of treatment, compared with about $6 for amoxicillin.

Points of Disagreement

Dr. Bluestone's changes disturbed Dr. Cantekin, who wasn't convinced that amoxicillin had been proven superior to a placebo. The two disagreed on several items, including the study's primary end point --the time at which the drug's effect is assessed. Dr. Bluestone thought it should be four weeks. Dr. Cantekin, arguing that ear infections often recur, decided on eight. The data showed that after four weeks, a small percentage of children taking antibiotics had healthier ears than those on a placebo. But at eight weeks, the two groups had equal numbers of cures. In terms of scientific protocol, both researchers' choices were justifiable. Indeed, a panel of experts that reviewed Dr. Bluestone's research for the federal Office of Scientific Integrity found "no substantial evidence indicating willful misrepresentation or a serious deviation from commonly accepted practices."

Dr. Cantekin, however, believed that amoxicillin's efficacy was still open to question, and that the new arms of the study were therefore useless. "Every new drug has been compared with amoxicillin,' he says. "If the benchmark is only as good as a placebo, the whole thing is a house of cards." Although he himself had accepted funding from drug companies in the past, Dr. Cantekin decided to stop. He told the chairman of his department that he no longer wished to work on privately funded research.

Even then, Dr. Cantekin was one of only a handful of biomedical researchers who shunned industry funds. Since the early 1980s, connections in biomedicine between academics and drug companies have become so pervasive that a recent footnote to an article on antidepressants in the New England Journal of Medicine disclosed more than 350 financial ties between the authors of the article and pharmaceutical companies that sell antidepressants.

Many members of the medical establishment say cooperation between universities and industry is crucial, given rising research costs and the desire to attack disease swiftly and systematically. "Not to have a (public-private partnership] to study and bring to market new drugs would be a terrible thing," says Steve Bennan, president of the American Academy of Pediatrics. "The industry budget far outweighs the government budget for some kinds of research. It's absolutely essential that industry be involved."

But such connections may have other, less visible consequences. The interlocking interests tend to protect the status quo by suppressing dissent and give the false impression that there is no doubt, disagreement or error ,in biomedical research. "In an environment where there seems to be a lot of uncertainty, you may not get the level of funding you want," says Edward Dangel of the Boston law firm of Dangel & Fine, one of Dr. Cantekin's lawyers. "You don't want to look disorganized."

At Pittsburgh, as at most other research universities, industry money has helped to step up the pace and rewards of innovation. For the fiscal year ended June 30, 1999, Pittsburgh received more than $36.3 million in corporate grants, about 11% of overall research funding.

While Pittsburgh was encouraging private industry to fund biomedical research, the National Institutes of Health was also unfazed by researchers commingling government and industry money. In the early 1980s, neither the NIH nor most research universities had formal conflict-of-interest guidelines. Scientists were assumed to be impervious to financial temptations, and while disclosure of private funding was required on grant applications, it wasn't considered relevant to a project's merit.

"It was common knowledge that [Dr. Bluestone] was partially supported by drug company money," said Ralph Naunton, a former official of the National Institute on Deafness and Other Communication Disorders, in a deposition. "We had Dr. Bluestone's verbal assurance that there was no conflict." (Dr. Naunton has since retired and couldn't be reached for comment.)

In 1985, with their data complete, Dr. Cantekin and Dr. Bluestone found themselves in an unusual position: Using the same statistics, Dr. Bluestone judged antibiotics useful for ear infections, while Dr. Cantekin declared the opposite. Dr. Cantekin tried to persuade other members of the research team that he was right and Dr. Bluestone wrong. Dr. Cantekin "was rigid," Dr. Bluestone told the Office of Scientific Integrity in 1989. "He only wanted it presented his way. He did not listen to anybody else. His co-authors had other opinions, and I felt their opinion was the best." So Dr. Bluestone, the study's senior investigator, wrote the official paper, and in the summer of 1986 submitted it to the New England Journal of Medicine.

Academia has conventions for scientific disagreements, but Dr. Cantekin, whose grandfathers were revolutionaries who helped overthrow the Ottoman empire, isn't a conventional man. Rather than writing a dissenting letter to the editor, he took the step that would destroy his career: He drafted a separate report of the study with his own conclusions and submitted it to the New England Journal of Medicine. Now holding two reports on the same study, the medical journal asked officials at Pittsburgh to choose one paper for publication. University officials responded by saying that only Dr. Bluestone was authorized to publish the data.

For the next five years, Dr. Cantekin's accusations were considered --and mostly rejected --by several panels. All three university committees exonerated Dr. Bluestone. One NIH inquiry found that while Dr. Bluestone should have been more forthright about his acceptance of private-sector funds when applying for NIH grants, his conduct was excusable. Another NIH report, however, recommended that Dr. Bluestone be placed on five years of administrative oversight for "having analyzed the data from NIH-funded research in a manner biased toward the effectiveness of the antibiotics he had evaluated with public monies.

Meanwhile, in 1989, the NIH issued its first draft of conflict-of-interest guidelines for researchers, which would have been voluntary .The proposal resulted in a stonn of protest from universities and industry .Officials predicted that the requirement for scientists to divulge their financial holdings and divest themselves of stock in companies whose products they tested would cause "the U.S. biomedical industry to languish in a second-rate position," as one chief executive of a biotech company wrote to the NIH. It took six more years before the NIH produced a final draft.

In 1990, the congressional subcommittee on Human Resources and Intergovernmental Relations, which was holding hearings on misconduct in scientific research that posed public risks, excoriated both the university and the NIH for their handling of Dr. Cantekin's claims. Most troubling, the subcommittee reported, was that Dr. Cantekin's dissenting report had been, for all practical purposes, censored. "Evidence of the ineffectiveness of antibiotics would have been available to physicians and the public several years ago, if the medical school had not prevented Dr. Cantekin from publishing them," the panel noted.

But not even a congressional endorsement could rescue Dr. Cantekin from his exile in Pittsburgh, where he was still officially a member of the faculty, though his salary remained frozen at its 1986 level. He had no research projects, and he hasn't spoken to an official of the medical school for 15 years. Five times since 1986, Dr. Cantekin has arrived at his office to find a note on his door saying that his belongings had been moved somewhere else. Now he doesn't even bother to unpack his few boxes of books and papers. Nor will he turn on his office computer, which appeared mysteriously on his desk several months ago, in case his activities are being monitored. He brings his frustration home to his wife, a psychologist, and daughter, who has come to hate hearing her father talk about earaches. "My potential has been stolen from me," Dr. Cantekin says. "No one's going to hire me unless there's a revolution in the medical profession."

In April 1991, five years after the war had begun, two big events in the long-running dispute coincided. One was the publication by Dr. Bluestone's research team of another paper based on data collected during the clinical trials of 1981 to 1985. Again the team concluded that children with ear infections --in this case, acute otitis media, or painful and inflamed ears --"should routinely be treated with amoxicillin (or an equivalent antimicrobial drug)." A close reading of the data showed that children who hadn't received medication had a cure rate of 92.5%, compared with 96% of those who were treated.

Published in the journal of the American Academy of Pediatrics, the study became one piece of evidence for a federal panel then drawing up recommendations for the treatment of otitis media. The panel's Clinical Practice Guideline for parents stated that antibiotics "may increase chance (by about 14%) and speed of middle ear fluid going away. " The panel cited the Bluestone group's study in six of eight footnotes to a chart illustrating the efficacy of antibiotic treatment. "If a government agency advises you that antibiotics are good for children's ear infections, you don't think, 'Drug companies are behind that.' But in this case, they were," says Danielle Brian, executive director of the Project on Government Oversight in Washington, D.C.

The second big event of April 1991 was that Dr. Cantekin filed a lawsuit against Dr. Bluestone and Pittsburgh in U.S. District Court in Pittsburgh. Until then, Dr. Cantekin had avoided the legal system or any consideration of a financial settlement with the university. "The first thing Pittsburgh did when they found out [Dr. Cantekin] had retained me was to dispatch a lawyer to my office with a checkbook," says Robert Potter, a partner in the Pittsburgh law finn of Strassburger, McKenna, Gutnick & Potter in Pittsburgh. "The lawyer closed the door and asked, 'What does he want?' But for [Dr. Cantekin], it wasn't a question of money. You couldn't settle with him because you couldn't settle the scientific issue."

As his cause began to fade from public view, and antibiotic prescriptions continued to rise, Dr . Cantekin invoked the federal False Claims Act, which allows an individual to sue on the government's behalf for damages caused by another person's false claims. Enacted in 1863, the law has been used almost exclusively against defense contractors. But recently, it has also become an appeals court for academicians alleging scientific fraud against universities and scientists. If the whistle-blower's case is proved, he or she may collect as much as three times the amount of research grants that involved fraudulent claims. In his suit, Dr. Cantekin charged that Dr. Bluestone had fraudulently not disclosed his private financing in grant applications to the NIH. If the NIH had known of this drug company money, Dr. Cantekin asserted, Dr. Bluestone wouldn't have received his federal funding.

Dr. Bluestone and the university won the first legal round in 1998, when the district court issued a summary judgment in their favor. The judge, Donald E. Ziegler, noted that in June 1987, Dr. Bluestone had sent a letter to the NIH disclosing his private funding --"a cost-sharing arrangement was implemented," Dr. Bluestone had written, adding, "but it was not explained fully," That letter nullified the claim that Dr. Bluestone hadn't told the government about his private funding, the court said. Even if Dr. Bluestone had notified the NIH on his grant applications, as he was supposed to do, there was no evidence that his NIH funding would have been jeopardized, the judge decided.

Dr. Cantekin appealed to the United States Court of Appeals for the Third Circuit, and in September 1999, he won his first major victory in the long war. "One can easily infer," the appeals court said, that Dr. Bluestone's letter, which was sent after Dr. Cantekin had lodged his complaint to the NIH, "was not an expression of an honest oversight, but an attempt to cover up prior misconduct and limit its damage."

Material and Negative

Furthernore, two of the five members of the NIH panel that had approved Dr. Bluestone's grants said in affidavits that they hadn't known about his private funding. That infonnation would have had a "material and negative" impact on their funding decisions, both said. Finally, the appellate court found it unlikely that Dr. Bluestone may simply have misread the instructions on the application, which asked for a list of "all research support." The court noted that for a scientist, the best of both worlds is to enjoy the munificence of pri vate industry and a government imprimatur on their studies. "In investigating treatments that have a disputed efficacy and a high aggregate cost," the court said, "[Dr.] Bluestone can be reasonably expected to know of the government's heightened interest in avoiding bias." The appellate sent the suit back to the district court for trial, which hasn't been scheduled yet.

Conflicts of interest remain a contentious issue in biomedical research, particularly after the 1999 death of a young man undergoing gene therapy at an academic center whose director had a financial stake in the outcome of the procedure. But no one suggests that private industry , academia and the government should, or even could, disentangle themselves. As the saying goes, the only people without conflicts of interest are those who know nothing at all about the subject.

Erdem Cantekin wouldn't agree. But 15 years after having blown the whistle on what he believed was biased medical Iesearch, he has the whistle-blower's greatest regret. "If I had known the consequences would be so abrupt and severe," he says, "I wouldn't have done it."

Pneumococcal Vaccine and Otitis Media

by Dr. Erdem Cantekin

Transcibed by and made available by Families for Natural Living, www.FamiliesforNaturalLiving.org or FNLemail@aol.com. From the National Vaccine Information Center's Second International Public Conferene, "Science for Hope and Healing: Challenging the Status Quo" on September 8 - 10, 2000 in Arlington, Va. For more information on the NVIC see www.909shot.com

Erdem Cantekin, Ph.D., is Professor of Otolaryngology, University of Pittsburgh. An internationally recognized authority on otitis media and has studied causes and treatments for ear infection and sinusitis in his 25 year career. An early, outspoken critic of the overuse of antibiotics to treat ear infections, Dr. Cantekin has published more than 150 articles and abstracts in the medical literature on eustachian tube function, ear tube surgery, antibiotic resistance and conflicts of interest in biomedical research and manufacturer sponsored medicine.

Cantekin discussed the new Prevnar vaccine for pneumococcal, as endorsed by the American Academy of Pediatrics. "The alleged benefits for this new vaccine are greatly exaggerated and the risks are significant," said Cantekin. "The bacteria pneumococcus, with more than 90 serotypes, is a common pathogen. Though pneumococcus causes various diseases the carriage rate and serotype distribution rates in different groups are not know. Also, it is not known how pneumococcus transmutes itself into a pathogen. The role of pneumococcus in the microbiological balance is not known. It does contribute to 3,000 cases a year of meningitis, 50,000 a year of bacteremia, 500,000 cases of pneumonia, and seven million cases of otitis media or ear infections?

"With all of these unknowns, the vaccination of newborns with seven pneumococcal serotypes and possible eradication of those serotypes, is an uninformed experiment at best," said Cantekin.

"Unfortunately, our public health officials have no good estimates of these carriage rates in common populations. The rates of healthy newborns contracting these diseases are not well documented and yet to be determined. Yet in February 2000 Prevnar, a seven-valent, conjugate vaccine was approved for infants and toddlers. The FDA did not approve pneumococcal for pneumonia or otitis media. This approval was limited and paradoxical because three years earlier the New England Journal of Medicine the scientists had concluded that 'bacterial meningitis in the US is now a disease predominately of adults rather than infants and young children.'"

Cantekin pointed out that the study on Prevnar violated rules of internationally accepted methods of reporting clinical trials by publishing the results when they were incomplete. For example, regarding pneumonia there was no information at all. All the results were presented in a "confusing nonstandard format." Also, the control group for the study did not receive a placebo, but another meningitis vaccine.

Other questions remained unanswered: "If this HMO trial was going to be the only foundation to vaccinate every newborn in the United States, why were those findings, involving 38,000 captive HMO children, not published in a leading medical journal? The results were instead published in a journal well known to be the mouthpiece of drug manufacturers. It is also troubling that, prior to the publication of primary results, the medical economic analysis was rushed to publication in the Journal of the American Medical Association. Then a string of publications appeared in print - this was a well-organized effort to capture the newborn population as quickly as possible? Prevnar is not effective for otitis media or pneumonia and the prevention of meningitis data are inconclusive. Why does the American Academy of Pediatrics want our children to be immunized using Prevnar? Why are all those experts excited about this new vaccine? I'm afraid the answer does not lie in the scientific realm.

Endorsements by experts become more puzzling if we examine the adverse or peculiar effects of the vaccine in the HMO trial. As shown here, Prevnar had four times more seizures, four times more gastritis than the control group, significantly more developed asthma, one death in the Prevnar group. Strangely, there were twice as many SIDS in the control group, but remember the control group was receiving another experimental vaccine.

"The big push for Prevnar came from its supposed prevention of otitis media, even though it had not been approved for this use. The promise of saving children from this common, self-limiting disease now turned into persistent childhood pest, is an excellent strategy, for marketing. Every parent knows and abhors otitis media.

"Simple facts about otitis media is that 60 percent of the cases are viral, less than 40 percent are bacterial, and perhaps 25 percent of all otitis media is due to pneumococcus. In two days, 90 percent of the otitis cases resolve by itself without treatment. Regardless of these facts our experts for two decades have been recommending aggressive interventions, such as long duration antibiotic therapy and designer drugs, antibiotic prophylaxis and then followed by aggressive surgery. This clinical practice, not supported by existing scientific based evidence, fuels our $5 billion a year otitis media medical economics. So if Prevnar could stop the cycle of drug and slash, it would have been a great public benefit. But that is not the case. The FDA data both from Finland and the HMO trial show that the prevention benefit is less than four percent. Despite this, the economic spin goes on."

When the JAMA rushed to publish the economic analysis deployment of Prevnar in the US prior to the publication of the HMO trial results, Cantekin wrote a letter to the editor. In this letter he pointed out that all of the money the vaccine was supposed to save health care consumers would be saved without the vaccine if health care providers would stick to the clinical guidelines for the treatment of otitis media. His letter to the editor was rejected. "Prevnar will have the same effect that antibiotic abuse currently has because, by changing serotype, it will exert selective pressure on the microbial ecology. This vaccine is the perfect example of a profit driven health care with no checks and balances. In our $1 trillion health care system the public health for people's interest are supposedly in the hands of three government agencies: the FDA, the CDC, and the NIH. These three pillars of our public health system are more and more in the hand of expert panels and advisory committees with ad hoc appointed outsiders. Such experts dictate policies, control the complex biomedical information system, and directly influence the taxpayers' health and wealth. Those experts are frequently in the state of conflict of interest because they also serve those special interest groups who profit from their expert decisions. Most experts are in financial relationships with these special interest groups and are usually registered with the speaker offices of various manufacturers. In other words, they are paid lobbyist. The perils of such interlocking conflicts are dangerous to public health. With increasing frequency we witness the media exposures of these white coat crimes. I think it is time that a reform act was in order and the people demand better controls from the government to protect their health and their pocket books."

Honolulu/03/15/01 UNITED STATES OF AMERICA, ex rel.

ERDEM I. CANTEKIN, an individual v. UNIVERSITY OF PITTSBURGH, a nonprofit Pennsylvania corporation;

CHILDREN'S HOSPITAL OF PITTSBURGH, a non-profit Pennsylvania corporation; CHARLES D. BLUESTONE, an individual; United States of America, ex rel. Erdem I. Cantekin, Appellant (Amended pursuant to Clerk's order dated 1/7/99) No. 98-3552 UNITED STATES COURT OF APPEALS FOR THE THIRD CIRCUIT June 17, 1999, Argued September 29, 1999, Filed JUDGES: BEFORE: NYGAARD, STAPLETON and COWEN, Circuit Judges. STAPLETON, Circuit Judge, concurring. COWEN, Circuit Judge.

This case concerns a medical researcher's failure to disclose his industry funding on a number of grant applications that he submitted to the National Institutes of Health (NIH). The undisclosed funding included several million dollars from pharmaceutical companies making the drugs that the NIH paid the researcher to evaluate. On this appeal we must determine when a private party can properly bring a suit under the False Claims Act's qui tam provision, 31 U.S.C. 3730(b), which allows an individual to sue on the government's behalf for damages caused by another party's false claims. Congress has changed several times the rules limiting when a private party can bring a qui tam suit under the False Claims Act. We must resolve which of two versions of the Act apply to the various grant applications that the researcher submitted to the NIH and what effect each version has on the claims it controls.

A recent Supreme Court decision, Hughes Aircraft Co. v. United States ex rel. Schumer, 520 U.S. 939, 117 S. Ct. 1871, 138 L. Ed. 2d 135 (1997), discussed the retroactivity of the 1986 Grassley Amendments, Congress's latest change to the Act's qui tam rules. Applying Hughes, the District Court concluded that Erdem Cantekin, the appellant, could not pursue qui tam claims based on grant applications that Charles Bluestone, the researcher and appellee, submitted before October 27, 1986. Although our reasoning differs from the District Court's, we will affirm its ruling on these applications submitted in 1986 or earlier. For Cantekin's remaining qui tam claim, which was based on an application submitted after the effective date of the 1986 amendments, the District Court granted summary judgment in favor of Bluestone and the other defendants because the Court concluded that Bluestone did not knowingly omit his industry funding from the application. Contrary to the District Court, we conclude that genuine factual disputes preclude summary judgment on whether Bluestone knowingly submitted a false claim.


Both the appellant, Erdem Cantekin, and the appellee, Charles Bluestone, are professors of otolaryngology at the University of 1 The University of Pittsburgh and Children's Hospital of Pittsburgh joined Bluestone in applying for various grants and were also named as defendants. For convenience, we have referred throughout our opinion to the claims against Bluestone, but our analysis applies equally to the other named defendants.

Pittsburgh's medical school and have worked together on research since the early 1970s. As part of their collaboration, they created the Otitis Media Research Center to investigate acute otitis media and otitis media with effusion, two ear diseases common in children. Much of the research they conducted together focused on testing the effectiveness of various antibiotics, such as amoxicillin, in treating the different types of otitis media. This research was particularly significant because while the drugs are widely used, controversy continues about the desirability and effectiveness of using antibiotics for these conditions. Not only are there medical reasons for worrying about unwarranted use of antibiotics, but also according to Cantekin's brief, the public spends over half a billion dollars annually buying antibiotics to treat the various forms of otitis media.

To pursue the research on antibiotics, Bluestone submitted numerous grant applications to the NIH throughout the 1970s and 1980s and ultimately was awarded approximately $ 17.4 million. At the same time, Bluestone began receiving funding from various pharmaceutical companies to test the effectiveness of their antibiotics in treating otitis media. Collectively, this industry funding totaled approximately $ 3.4 million.

Cantekin claims that as early as 1976, he raised with Bluestone his failure to list his industry funding on his NIH grant applications, but Bluestone allegedly brushed him off, saying that he was not going to tell the "federal feather merchants" because it was "none of their business" and would "muddy up the waters." App. at 523. Cantekin also disputed Bluestone's interpretation of research results, in particular the results of several industry-funded studies.

In May of 1987, Cantekin wrote to the NIH complaining about Bluestone's conduct, but the NIH chose to take no action, instead deferring to an investigation conducted by the University of Pittsburgh. When the university announced on June 22, 1987 that it had cleared Bluestone of any wrongdoing, the NIH dropped the matter. Dissatisfied with the university's investigation and with the NIH's reliance on it, Cantekin later testified before the United States House of Representatives at hearings investigating scientific fraud in federally funded research. While the congressional report from the hearings was pending, the NIH decided to conduct its own inquiry into Bluestone's conduct. The resulting report by Howard Hyatt, then director of the NIH's Division of Management Survey and Review, concluded that Bluestone and the Otitis Media Research Center had "not generally disclosed to NIH the extent of its industry-sponsored research." App. at 508. But Hyatt continued that since the grant instructions were ambiguous, Bluestone's conduct was excusable. Hyatt also rejected Cantekin's claim that Bluestone's research results were biased.

On September 10, 1990, the House released its report, which discussed ten cases where grant recipients had engaged in misconduct. See H.R. Rep. No. 101- 688, Are Scientific Misconduct and Conflict of Interest Hazardous to Our Health?, 19th Report, Committee on Government Operations, 101st Cong., 2d Sess. (Sept. 10, 1990). Bluestone's case was included among the ten. The House report excoriated both the University of Pittsburgh's investigation as well as Hyatt's report and challenged many of their findings. Several months later, in December of 1990, the NIH issued a new report by the agency's recently created Office of Scientific Integrity (OSI), which had reopened the agency's inquiry into Bluestone's conduct. Dr. Suzanne Hadley, then Acting Deputy Director of OSI, was in charge of this second NIH investigation. Her affidavit explained that the OSI report recommended that the Director of NIH require that Dr. Bluestone be place on a period of five years of administrative oversight for having failed to disclose his private pharmaceutical company research to NIH and having analyzed the data from NIH-funded research in a manner biased towards the effectiveness of the antibiotics he had evaluated with public monies.

App. at 481. To illuminate how Bluestone's failure to disclose his industry funding could have affected the NIH's approval of his grants, Cantekin provided the following overview of the application process. Applications are first assigned to one of several institutes within the NIH. In Bluestone's case, his applications were sent to the National Institute for Neurological, Communication Disorders, and Stroke, which then forwarded them to the Communication Disorders Review Committee (CDRC), one of the review committees within the institute. A review committee is the body primarily responsible for evaluating the merits of applications like Bluestone's. Each review committee is composed of experts who are not NIH employees and are paid per diem for evaluating the applications. Frequently, the review committee members have themselves received NIH grants in conducting their own research.

The review committee takes two votes on an application. The first vote is to "approve" or "disapprove" the requested grant; receiving approval at this stage, however, does not assure that the application will be funded. The application may still be rejected based on the second vote, which establishes a "priority score." To determine the priority score, each member of the review committee gives the proposal a score between 1, for the highest priority, and 5 for the lowest. Each member's score is then added together, the total is divided by the number of members, and the resulting average is multiplied by 100, yielding the final priority score. Thus, the highest priority score possible is 100 and the lowest 500.

In 1984, Bluestone and Children's Hospital of Pittsburgh submitted an application to extend an earlier grant by five years. Their first request for an extension received a priority score of 154 and was not funded, but later Bluestone and the Otitis Media Research Center submitted a revised application that received a priority score of 131, which was good enough to receive funding.

If we combine the NIH's method of calculating the priority score and the rough guideline that an application with a score of 154 or higher would not receive funding, at least around the time that Bluestone's application was considered, we can see that one or two members can easily raise an applicant's priority score above the cut-off for funding. For example, votes of 1, 1, 1, 1, and 5 yield a priority score of 180; and votes of 1, 2, 1, 1, and 3 yield a score of 160. Even votes of 1, 1, 1, 1, and 3 could place an applicant on the edge of rejection with a priority score of 140. After the priority vote, an executive secretary, who functions as a staff member for the committee, writes a report describing the review committee's deliberations and submits the report to the Council of the Institute. The council receives applications from the various review committees within the institute and makes the final determination of which applications will be funded. Council members, like the review committee members, are not NIH employees and are chosen for their expertise in their field. Unlike the review committee members, however, council members are appointed to serve for four year terms.

Once a multi-year grant has been approved for funding, NIH assigns the grant to a "program administrator," who is in charge of administering the grant. Each year the grant's principal investigator, Bluestone in our case, and the grantee institution must submit a special continuing application, or progress report. These progress reports are "noncompetitive" in that funding during the allotted time has already been approved. The purpose of the progress reports is to informed the NIH of how the research is advancing, identify the amount of the budget for the next year, and provide information about key personnel engaged in the research.

Two of the five members of an NIH review committee that voted to approve one of Bluestone's grants stated in affidavits that if they had known about his industry funding, it would have affected their decision. Dr. Perkell, one of the review committee members, said that Bluestone's undisclosed industry funds were not "common knowledge." He continued: It is my opinion that had Dr. Bluestone disclosed his relationships with the private pharmaceutical industry, the competing renewal application of NS 16337 which came before the Review Committee of which I was a member would have been evaluated more critically with regards to: demands on investigator time, possible conflicts of interest, the effects of bias on the value of the proposed studies, safeguards in the study design to ensure unbiased interpretation and evaluation of the results of the proposed studies. The more critical evaluation would have had an impact on the recommendation for approval and on the priority score. The impact on the priority score I gave would have been material and negative. In my opinion, based on my knowledge of past behavior of my fellow members of the Review Committee in evaluating and assigning priority scores to several hundred other applications the impact on the overall priority funding score would have been material and negative.

App. at 473-74. Dr. Schwartz, the chair of the review committee, also stated in an affidavit that she was unaware of Bluestone's industry funding and that had she known, it would have had a "material and negative" effect on her evaluation of the application. She explained that a researcher who receives substantial funding from a pharmaceutical company can be subtly biased in favor of finding that the company's drugs are effective. Disclosure of this potential source of bias is important to reviewers even if the grant might be ultimately approved since the review committee might not approve the application until certain additional safeguards are implemented. "When bias, or potential bias, are revealed by disclosure of a funding source with a vested interest in the outcome of the research, reviewers are alerted to look for defects in the experimental design which could compromise the work proposed." App. at 1125. Elsewhere, she explained: A bias experimenter can still perform valid work, but the experiments must be carefully designed so that enrolled patients are randomly assigned to different test groups, objective criteria for measuring function are used, and both subject and observer are blinded as to which experimental condition (i.e. new drug, current standard drug, or other control substance) applied to a particular subject. Appropriate statistical tests must be applied to the data to assure that interpretations of efficacy of the test drugs are valid.


The three other members of the review committee, Drs. Miller, Meyerhoff, and Goode, all submitted affidavits saying that they were aware of Bluestone's industry funding. Dr. Miller, for example, stated that "I was fully aware that Dr. Bluestone was receiving very substantial support from private pharmaceutical companies to do drug efficacy studies. . . . I was not at all troubled by the fact that Dr. Bluestone was receiving such funding." App. 1104-05. None of the three, however, informed Drs. Perkell or Schwartz of this outside funding. Dr. Schwartz's affidavit notes that the other committee members did not mention Bluestone's undisclosed funding at the review committee meetings, nor did they "raise the issue of possible conflicts of interest or of the adequacy of safeguards to control against bias in the interpretation of study results..." App. at 1125.


We have jurisdiction pursuant to 28 U.S.C. 1291, and we exercise plenary review of a district court's grant of summary judgment. Barnes v. American Tobacco Co., 161 F.3d 127, 138 (3d Cir. 1998). On a motion for summary judgment, a court must determine whether the evidence shows that "there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(c). Factual disputes invoked to resist summary judgment must be both material in the sense of bearing on an essential element of the plaintiff's claim and genuine in the sense that a reasonable jury could find in favor of the nonmoving party. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248-251, 106 S. Ct. 2505, 2510-12, 91 L. Ed. 2d 202 (1986). A court should not prevent a case from being presented to the jury simply because the court favors one of several reasonable views of the evidence, for "the judge's function is not himself to weigh the evidence and determine the truth of the matter but to determine whether there is a genuine issue for trial." Anderson, 477 U.S. at 249, 106 S. Ct. at 2511.


We begin with the threshold issue of which grant applications can be subject to a qui tam suit. Prior to the 1986 amendments to the False Claims Act, a private party was barred from bringing a qui tam suit if the action was "based on evidence or information the Government had when the action was brought." 31 U.S.C. 3730(b)(4) (1982 ed.). The government itself, of course, could still bring suit for such a violation; only private parties were barred from seeking recovery. The implicit logic of the pre-1986 law was that if the government had the relevant information before the plaintiff initiated suit, then the government must be aware of the false claims and didn't need the assistance of private parties to ferret them out. And if the government knew about the information yet did nothing, then the government probably thought the suit meritless, and any private action was apt to be spurious, driven only by the lure of the Act's sizable damages. Despite the pre-1986 law's legitimate aim of preventing spurious suits, its bar for qui tam suits imperfectly achieved its purposes for a variety of reasons: 1) the government lacks the resources to investigate and prosecute all false claims even when the government has information revealing fraud; 2) a government official who is deemed to "have" the information may not recognize the connection between the information and a particular false claim; 3) the official may have an interest in not bringing the fraud to light for a number of reasons, such as an interest in protecting the official's or the agency's reputation; and 4) other mechanisms, more directly focused on the merits of a suit, are available for filtering out spurious claims. Congress was also concerned that under the old law, whistleblowers who came forward and exposed fraud to government officials before filing suit were later being barred from bringing a qui tam suit. Indeed, as our discussion below makes clear, Cantekin's case itself illustrates this consequence of the pre-1986 law.

With the enactment of the Grassley Amendments, Congress generally gave greater scope to qui tam suits. Among other changes, such as increasing the damages from double to treble the harm caused, and increasing the percentage that a qui tam plaintiff received of those damages, compare 31 U.S.C. 3730(a) and (c) (1982 ed.) with 31 U.S.C. 3730(d)(1) and (2), the amendments also eliminated the old law's bar to qui tam suits. Instead of prohibiting all qui tam suits that are based on information the government "has" when the suit is brought, the Grassley Amendments introduced a new standard: a qui tam suit will be barred only if it is based on information that was "publicly disclosed" at various hearings, in certain types of reports, or by the media. 31 U.S.C. 3730(e)(4)(A). Information that the government "has," but that was never publicly disclosed, does not bar a qui tam suit. Even if there is "public disclosure" within the meaning of the Grassley Amendments, a qui tam suit can still go forward if the plaintiff is an original source of that publicly disclosed information. 31 U.S.C. 3730(e)(4)(B). An original source is defined as someone who has "direct and independent knowledge" of the information and who has "voluntarily provided" the government with the information before the suit was initiated. Id. Groundless suits are addressed in part by provisions requiring that all qui tam plaintiffs submit sealed information to the government before the suit proceeds. After reviewing this information, the government can decide whether to join the suit, allow the private party to continue alone, or, most significantly, dismiss the suit. See 31 U.S.C. 3730(b)(2) and (c)(2)(A). In Hughes Aircraft Co. v. United States ex rel. Schumer, 520 U.S. 939, 117 S. Ct. 1871, 138 L. Ed. 2d 135 (1997), the Supreme Court held that the 1986 amendments did not apply retroactively to conduct occurring prior to the amendment's effective date. The Court stated in a footnote, however, that since in Hughes both the "false claim submission" and the "disclosure to the government" of the fraud occurred before the effective date of the 1986 amendments, the Court did not have to address which of the two events should be used for determining retroactivity. 520 U.S. at 946, n. 4, 117 S. Ct. at 1876, n.4.

In applying Hughes, the District Court concluded that for all of Bluestone's grant applications submitted prior to the 1986 effective date, the date of "disclosure to the government" also occurred before October 27, 1986. Thus, the District Court decided that, as in Hughes, it did not have to resolve whether the disclosure date or the date of submission controls.

Although the parties sharply dispute whether there was "disclosure to the government" prior to the 1986 effective date, we need not resolve the issue. We conclude that even though the Supreme Court did not expressly reach in Hughes whether retroactivity is determined based on the submission date or the disclosure date, the Court's analysis strongly supports using the former, i.e., the date the allegedly false claim was submitted. And once we use the submission date and apply the pre- 1986 law to all grant applications submitted prior to the October 27, 1986 effective date, there can be no doubt that before Cantekin began his qui tam suit, the government "had" the information upon which it was based.

By the time Cantekin filed his complaint in the District Court on April 29, 1991, the House had conducted its hearings and issued its report, and the NIH had issued both Hyatt's memo and the later report by the Office of Scientific Integrity. These events unquestionably establish that the government had the information on which Cantekin's suit was based.2 Thus, the only live issue is why we should use the submission date for determining retroactivity. When the Supreme Court concluded in Hughes that the Grassley Amendments should not be applied retroactively, the Court recognized that knowingly submitting a false claim is illegal under both versions of the statute. The Court also noted that under both the amended statute and the previous statute, the total amount of a defendant's liability does not depend on who sued; the defendant must pay the same amount regardless of whether the government or a qui tam relator brought the action. Nonetheless, the Supreme Court reasoned that the amendment's change in when qui tam suits can be brought does impose new penalties on defendants.

While we acknowledge that the monetary liability faced by 2 Cantekin objects that when the District Court granted summary judgment against his pre-1986 claims, the Court erred by converting a 12(b)(6) motion into a motion for summary judgment without first giving adequate notice and an opportunity to respond. See, e.g., Rose v. Bartle, 871 F.2d 331, 342 (3d Cir. 1989). Cantekin raised this point in a motion for reconsideration, but the District Court rejected the argument, noting that under Rose a failure to give notice can be excused if "harmless." Id. Since we evaluate retroactivity based on the submission date, and since it is undisputed that Cantekin's suit was filed after the NIH and Congressional investigations, we conclude that any error stemming from the conversion of the motion was indeed harmless.

2 an FCA defendant is the same whether the action is brought by the Government or by a qui tam relator, the 1986 amendment eliminates a defense to a qui tam suit -- prior disclosure to the Government -- and therefore changes the substance of the existing cause of action for qui tam defendants by "attaching a new disability, in respect to transactions or considerations already past." 520 U.S. at 948, 117 S. Ct. at 1877 (citations omitted). After noting that the 1986 amendments eliminate a defense, the Court commented that the amendments also in effect create a new cause of action because the courts are open to an expanded class of plaintiffs. We think this reasoning would be in deep tension, if not outright conflict, with using the date of disclosure instead of the date of submission for determining retroactivity. Our primary rationale is very simple. If we invoked the disclosure date to apply the amendments to a false claim submitted before the amendment's effective date, then the new penalties listed by the Court, i.e., the loss of a defense and the creation of a new cause of action, would be imposed after the defendant acted. The reason that using the disclosure date would have this effect is that the defendant's conduct ends with submitting the false claims; the defendant is not the one, or at least not usually, who makes the disclosure to the government. Since the Court rejected in Hughes an application of the Grassley Amendments that would allow the law to "attach new disabilities" to conduct committed prior to the amendment's passage, we think the Court implicitly foreclosed using the disclosure date. Another problem with using the date of "disclosure to the government" to determine retroactivity is that it is not clear what test should be applied to determine that date. The Supreme Court's phrase "disclosure to the government," straddles the 1986 amendment's "public disclosure" language and the pre- 1986 standard of "information the government had." By speaking of disclosure "to" the government, rather than disclosure "by" the government, the Supreme Court's language may suggest that the Court was referring to the pre-1986 "government knowledge" test. The "government knowledge" test is primarily focused on what other people release to the government while the amendment's "public disclosure" test has a substantial emphasis on information released by government . On the other hand, the Supreme Court's phrase, "disclosure to the government," does not accurately capture the pre-1986 law since the government could "have" the information within the meaning of the pre-1986 test based on what the government learned from its own investigative efforts. And by speaking of "disclosure," and not information the government "has," the Supreme Court's language is suggestive of the "public disclosure" test.

Regardless of how one parses the language, however, the real problem is that choosing between the pre- and post-1986 standards injects a kind of circularity into the retroactivity analysis. To determine the date of "disclosure to the government," we must apply either the pre-or post-1986 test in order to decide whether we will apply the pre- or post-1986 test to the alleged false claim. This awkward need to stipulate at the outset what our analysis is supposed to decide reinforces our conclusion that the date the claim was submitted should determine the retroactivity of the Grassley Amendments.3

The District Court noted in passing that a Ninth Circuit opinion, decided before the Supreme Court's opinion in Hughes, relied on the disclosure date for determining the 3 It is true that a court could apply pre-1986 law to assign a date to the "disclosure to the government" and yet still find that post-1986 law should ultimately control the claim. For example, suppose that after the defendant submitted a false claim in 1985, the plaintiff informed the government of the fraud in 1987, filed a qui tam suit in 1988, and qualified as an original source. Even if we applied the pre-1986 law to date "disclosure to the government," we would not bar the plaintiff's suit. This follows because the date that the government learned of the fraud, i.e., sometime in 1987, was after the effective date of the 1986 amendments. And once we applied the amended law, we would see that the plaintiff could go forward with the suit since the plaintiff is an original source, and no public disclosure occurred aside from the plaintiff's suit.

The circularity of our presupposing pre-1986 law isn't really eliminated, however, just because in a certain class of cases using the pre-1986 law to assign a date to disclosure leads us to apply post-1986 law. We still need a justification for applying the pre- 1986 law at the outset when it may foreclose many claims that the post-1986 disclosure test would not. We could, of course, appeal to the considerations cited in Hughes for using the pre-1986 law. But once we adopt those arguments, we have reason to abandon the "date of disclosure" altogether as a way of determining retroactivity. retroactivity of the Grassley Amendments. See United States ex rel. Anderson v. Northern Telecom., Inc., 52 F.3d 810, 814 (9th Cir. 1995). The main problem with Anderson is that its reasoning rested heavily on the point that "the 1986 amendment did not change the legal consequences of [defendant] Northern Telecom's conduct." 52 F.3d at 814. Since Hughes rejected that position and emphasized that the Grassley Amendments do "attach new disabilities" to a defendant's past conduct, we think that Anderson's authority has been undermined. In short, we conclude that we should use the date the claim was submitted for determining the retroactivity of the Grassley Amendment's "public disclosure" bar to qui tam suits.

Did Bluestone knowingly submit false claims? Not all of Cantekin's claims were based on grant applications submitted prior to October 27, 1986. On January 28, 1987, Bluestone submitted a new grant application without listing his industry funding, and he again failed to disclose when he revised the application on May 1, 1987. The District Court dismissed Cantekin's qui tam claim based on this revised application because the Court concluded on summary judgment that the evidence "does not permit a finding that Dr. Bluestone 'knowingly' submitted false or fraudulent claims to the government." App. at 1627. The False Claims Act defines "knowing" and "knowingly" as including a defendant's "actual knowledge," "deliberate ignorance," or "reckless disregard" of the truth or falsity of information in the defendant's claim to the government. 31 U.S.C. 3729(b). The statute adds that "no proof of specific intent to defraud is required." Id. In applying these 1standards to the record before us, we must heed the basic rule that a defendant's state of mind typically should not be decided on summary judgment. See, e.g., Hunt v. Cromartie, 526 U.S. 541, 119 S. Ct. 1545, 1552, 143 L. Ed. 2d 731 (1999).

The District Court's primary rationale for granting summary judgment was that the grant application and instructions were unclear. Before we address whether the instructions are ambiguous, or more properly whether there is no genuine dispute that they are, we note that Cantekin stated in his affidavit that he specifically informed Bluestone that he should disclose his private funding. In 1976, when Dr. Bluestone and I were applying for various NIH grants, I raised with Dr. Bluestone the question whether he, as principal investigator, should not be disclosing to NIH his other research support, especially from pharmaceutical companies. Dr. Bluestone replied that it was "none of their business," and that he was not going to tell the "federal feather merchants" because it would "muddy up the waters." Dr. Bluestone added that "idiots like Buckminster Ranney would not understand." Dr. Buckminster Ranney was an NIH-employee working with the National Institute of Neurological, Communicative Disorders, and Stroke ("NINCDS") with whom Dr. Bluestone had dealt.

App. at 523. This affidavit not only creates a genuine dispute that Bluestone "knowingly" omitted his industry funding, but it also provides evidence that Bluestone had the specific intent to defraud, proof of which is not required for a violation of the False Claims Act.

Even apart from the evidence that Bluestone was specifically informed that he should disclose his industry funding, we conclude that there is ample evidence that the instructions are clear. Other members of Bluestone's Otitis Media Research Center correctly followed the instructions and disclosed their outside research funding, including private sources. App. at 38. Similarly, one of the NIH review committee members, Schwartz, stated in her affidavit that: I have written or helped to write numerous NIH grant applications for fellowships, research grants, program projects and training grants. As principal investigator I have held an R01 grant from NIH which has been continuously funded since 1972 involving seven competing renewals and several revised resubmissions . . . I have always found directions for completing the "other support" pages of NIH grant applications to be unambiguous. App. at 439-40. Another member of the review committee, Perkell, submitted a similar affidavit saying that he had applied for and received a number of NIH grants and found the "other support" section to be unambiguous.

A review of the instructions themselves suggests that they clearly indicate that industry funding should be disclosed. On the page that instructs applicants to list their "other support," the form provides: For each of the professionals named on page 2, list, in three separate groups: (1) 11 active support; (2) applications pending review and/or funding; (3) applications planned or being prepared for submission. Include all Federal, non-Federal, and institutional grant and contract support. If none, state "NONE." For each item give the source of support, identifying number, project title, name of principal investigator / program director, time or percent of effort on the project by professional named, annual direct costs, and entire period of support. (If part of a larger project, provide the titles of both the parent grant and the subproject and give the annual direct costs for each.) Briefly describe the contents of each item listed. If any of these overlap, duplicate, or are being replaced or supplemented by the present application, justify and delineate the nature and extent of the scientific and budgetary overlaps and boundaries.

App. at 1196 (emphasis in original). The instructions specifically request that the applicant list "all... non- Federal... support" and give detailed information about each grant.

In concluding that the instructions were ambiguous, the District Court relied on Hyatt's report, which cited an earlier version of the instructions and said that "many institutions were found to interpret those instructions improperly." App. at 509. Hyatt explained that the NIH changed the instructions to avoid ambiguities. The District Court's reliance on Hyatt's memo is problematic for a number of reasons. First, Bluestone's post-1986 grant applications used the improved instructions. Second, even if potential confusion from the earlier applications was relevant, perhaps because the earlier instructions gave Bluestone erroneous expectations, we seriously question whether the earlier instructions were ambiguous. The instructions that Hyatt claimed were ambiguous read in part: List all research support for each individual including requests now being considered, as well as any proposals being planned, regardless of relevance to this application. Include also current awards, research career program awards, training grants, regardless of the source of support. App. at 509. Hyatt apparently believed that these instructions were ambiguous because, unlike the improved instructions, they did not specifically refer to "non-Federal" sources. The instructions did, however, direct applicants to list "all" research support "regardless of source" and "regardless of relevance." Hyatt claimed that "many" institutions had incorrectly interpreted the earlier instructions, but the drafter of the NIH forms testified that he could not recall any specific case, except Bluestone's of course, where a researcher misunderstood what was required by the "other support" question.

Third, the House report sharply criticized Hyatt's conclusions and explained that: NIH officials were incorrect in describing the content of the NIH forms; the section regarding "Other Support" was revised in late 1979 and revised forms, containing the more explicit language were 1available to applicants in 1980 or 1981, depending on the type of application. App. at 38.

Fourth, Dr. Hadley, the Acting Deputy Director of the NIH's Office of Scientific Integrity, asserted in her affidavit that she had not encountered any evidence that applicants found the instructions to be ambiguous. In my opinion and based on my [prior] experience as an Executive Secretary [who works with review committees in evaluating grant applications,]... there was never any problem with ambiguity in PHS instructions on how to complete the "Other Support" section of a PHS Grant Application or Continuation Application. From Fall, 1979 on, the instructions explicitly required the disclosure of all sources of support, both federal and non-federal. App. at 482.

Finally, one can infer that Bluestone, a highly-educated professional, would have been aware that the NIH might be interested in his industry ties when the agency decided whether to award him substantial funding to test a key drug in a half-billion dollar industry. As Cantekin points out, people are likely to give much greater weight to NIH research than to the findings of companies making the drugs at issue. Given this greater public trust in the results of government-funded research, and the undeniable risks of bias, the government clearly has a strong interest in ensuring that it acts as an impartial investigator, especially when investigating treatments that have a disputed efficacy and a high aggregate cost. Bluestone can be reasonably expected to know of the government's heightened interest in avoiding bias. As a scientist, he must be fully aware that rooting out potential sources of bias in our interpretations of empirical data is central to scientific inquiry.

The District Court and the appellees' next argument is that in the materials accompanying some of Bluestone's applications, there were references to his industry funding. These references were by no means complete disclosures of the grants he was receiving from pharmaceutical companies, nor did the references include the full information, such as the amount of the funding, that was requested in the "Other Support" section of the grant application. Furthermore, many of the references that the appellees rely upon were included with "progress reports," which were submitted after a grant was approved. But the most important point is that scattered references buried in voluminous accompanying materials do not comply with the application's disclosure requirements.

When a reviewer is faced with complex proposals that include large masses of accompanying information, it makes sense to insist that the applicants must disclose in one place the applicant's other grants that may raise conflicts of interests or impose competing demands on the applicant's time. A reviewer who is reading an applicant's accompanying journal article may not notice, while engrossed in the details of a specialized scientific issue, a fleeting reference to private funding and think of its significance for potential conflicts of interest. Applications distill and organize information for a reason.

Evidence in the record bears out this point. One of the review committee members, Perkell, stated in his affidavit that: As a grant reviewer and evaluator I have always looked to the "Other Support" pages to form an estimate of the percentage of effort the Principal Investigator and other investigators have available to do the proposed work, to look for possible overlap between proposed projects and others already funded or pending, and to identify possible conflicts of interest or possible sources of bias in the experiments. These factors are important to me in evaluating an application as a whole and in assigning it a priority score.

App. at 472. Schwartz, another review committee member, likewise stated in her affidavit that she relies on the "Other Support" section to gauge how much time the applicant has to spend on the research, whether the proposal is duplicative, and what conflicts of interest the applicant might have. Despite the references Bluestone cites in the accompanying materials, neither Schwartz nor Perkell was aware of Bluestone's industry funding, and both said it would have affected their evaluation of his application. The District Court's last reason for concluding that Bluestone did not knowingly submit a false claim is that he sent a letter on June 23, 1987 to Elkins, his program administrator, listing his industry funding. We find the District Court's reliance on this letter unconvincing. Not only was it written months after Bluestone submitted his application in January and May of 1987, but more important, the letter was only sent after he was under investigation. Given that Bluestone only sent the letter after Cantekin made his allegations to the NIH and the university, the timing of the letter tends to reinforce, not undermine, Cantekin's allegations that Bluestone knew that he was supposed to disclose his industry funding. One can easily infer that the letter was not an expression of an honest oversight, but an attempt to cover up prior misconduct and limit its damage.

Cantekin alleges that program administrators' interests are more closely allied with grant applicants' than any other NIH official, so it is noteworthy that Bluestone chose to notify Elkins, and Elkins alone, at the NIH. Reading the evidence in the light most favorable to the nonmoving party, we note that if Bluestone calculated that disclosure to Elkins would be the least damaging step he could take, his judgment apparently proved correct since the letter he sent to Elkins was never forwarded beyond the programadministration offices.

Another problem with relying on Bluestone's letter to Elkins as a way of exonerating him for submitting a false claim is that the False Claims Act has a specific provision dealing with someone who comes forward and discloses his or her false claims. The statute provides that: If the court finds that -- (A) the person committing the violation of this subsection furnished officials of the United States responsible for investigating false claims violations with all information known to such person about the violation within 30 days after the date on which the defendant first obtained the information; (B) such person fully cooperated with any Government investigation of such violation; and (C) at the time such person furnished the United States with the information about the violation, no criminal prosecution, civil action, or administrative action had commenced under this title with respect to such violation, and the person did not have actual knowledge of the existence of an investigation into such violation; the court may assess not less than 2 times the amount of damages which the Government sustains because of the act of the person. A person violating this subsection shall also be liable to the United States Government for the costs of a civil action brought to recover any such penalty or damages.

31 U.S.C. 3729(a)(7). The first point worth noting is that this provision merely reduces the defendant's liability from treble to double damages; it does not exonerate a defendant for a violation. Second, Bluestone's letter of June 23 was more than 30 days after the date he made his false statements. Third, Bluestone's letter was sent after he was under investigation, and thus he arguably cannot satisfy subsection (C). It also may be open to dispute whether he has "fully cooperated" or provided "all information" that he knew about the violation.

Taking up a different issue, the District Court cited United States ex rel. Hopper v. Anton, 91 F.3d 1261, 1266-67 (9th Cir. 1996) for the proposition that a "technical violation of rules and regulations of an agency is not actionable under the FCA." App. at 1627. What the Ninth Circuit held in Hopper, however, was that not every regulatory violation is tantamount to making a knowingly false statement to the government. Since the regulatory violation in Hopper did not involve making a knowingly false statement in a claim submitted to the government, the court held there was no violation of the False Claims Act. Thus, Hopper does not stand for the proposition that before a court allows a suit to proceed under the False Claims Act, it must weigh how serious it thinks a particular knowing falsehood was in a claim submitted to the government. Although we reject the District Court's reading of Hopper, the Court's remark about "technical violations" suggests two slightly different objections: Bluestone's omissions were not material, and even if they were, they did not cause any damages to the government. We will consider first the materiality objection. Courts have held that claims under the False Claims Act are subject to a judicially imposed materiality requirement. See, e.g., Harrison v. Westinghouse Savannah River Co., 176 F.3d 776, 784 (4th Cir. 1999). And the Supreme Court recently held in Neder v. United States, 527 U.S. 1, 119 S. Ct. 1827, 144 L. Ed. 2d 35 (1999) that there is a materiality requirement under the federal mail-fraud, wire-fraud, and bank-fraud statutes. In a footnote, the Supreme Court indicated, however, that the term "false statement," unlike "fraudulent statement," does not imply a materiality requirement. Neder, 119 S. Ct. at 1840 n.7. Given that the False Claims Act prohibits merely making a knowingly false claim and does not require a specific intent to defraud, perhaps Neder argues against a materiality requirement. In any event, we need not decide whether there is a materiality requirement under the False Claims Act, because even if there is, we think it is clear that Bluestone's failure to disclose his industry funding would readily qualify as material. In Neder, the Supreme Court quoted from the Restatement (Second) of Torts, which provides two alternatives for showing that a matter is material: (a) a reasonable man would attach importance to its existence or nonexistence in determining his choice of action in the transaction in question: or (b) the maker of the representation knows or has reason to know that its recipient regards or is likely to regard the matter as important in determining his choice of action, although a reasonable man would not so regard it. Neder, 119 S. Ct. at 1840 n.5 (quoting Restatement (Second) of Torts 538 (1976)). As recounted above, industry funding is relevant for assessing conflicts of interest, how much time an applicant has to devote to the requested NIH grant, and how the research fits within a broader research program. Because the NIH specifically requests the information on its form, and because the value of this information is readily apparent, we think that the information is material: a reasonable NIH grant applicant would know that the NIH regards the information as important.

We turn now to the issue of damages. Even if the letter to Elkins does little to undermine Cantekin's claim that Bluestone knowingly submit false claims, the appellees argue that the letter still shows that his earlier failure to disclose caused no harm. Bluestone sent the letter to Elkins on June 23, 1987, but his pending post-1986 application was not finally approved until February 4, 1988, when he was awarded $ 321,137. The appellees argue, therefore, that no harm could have been caused because Bluestone disclosed his industry funding before any grant money was dispensed for his post-1986 grant application.

The first problem with this argument is that, as noted above, the letter to Elkins never left the program-administration offices, so the information about Bluestone's industry funding never reached the review committee or any other decisionmaker involved in approving Bluestone's grant. Thus, we do not know whether the review committee or the council of the institute would have approved the grant if they had known about the information included in the letter. Given that two committee members who reviewed Bluestone's application in 1984 and 1985 would have assigned lower priority scores to his application, and given that one member's vote can effectively deny funding, we think whether the grant would have been approved and what damages were incurred raise genuine factual disputes. We also want to point out that even if the review committee and council would have approved the application once they knew about the industry funding, they still might have imposed additional safeguards or requirements. Having not been informed, they did not have an opportunity to consider these other intermediate steps.

It may seem unfair to hold Bluestone accountable for the decision made in the program administration offices not to pass along Bluestone's letter. As noted above, however, the statute expressly provides a mechanism for dealing with a defendant who reveals his false claim. Since this provision merely reduces the defendant's liability for the damages actually caused, and since, in any event, Bluestone may not satisfy the prerequisites, Bluestone remains liable for the harm that in fact was caused to the government as a result of his false statements.

It is a basic principle of tort law that once a defendant sets in motion a tort, the defendant is generally liable for the damages ultimately caused, unless there are intervening causes. See, e.g., W. Keeton, D. Dobbs, R. Keeton, & D. Owen, Prosser and Keeton on Law of Torts 44 (5th ed. 1984). Analysis of intervening causes is often used as a way of evaluating and assigning responsibility for harm caused. Id. Given that Bluestone only sent his letter after he was under the pressure of investigation, his letter does little to lessen his culpability, and therefore, the fact that the letter was not forwarded is not plausibly treated as an intervening cause. To the extent that analysis of intervening causes focuses on the foreseeability of a putative intervening cause, we think it is significant that Bluestone chose to send the letter to Elkins, his program administrator, who did not decide whether he would receive funding for his application. Bluestone did not, for instance, submit another revised application as he did earlier in the spring. In short, the fact that the letter was not forwarded was a risk that Bluestone assumed when he submitted the claims.

The appellees have directed our attention to several cases discussing causation requirements under the False Claims Act. In United States v. First Nat'l Bank of Cicero, 957 F.2d 1362 (7th Cir. 1992) the court held that the government only needed to show that it would not have made a payment "but for" the false statement. In reaching that holding, the Seventh Circuit expressly disagreed with United States v. Hibbs, 568 F.2d 347 (3d Cir. 1977), which, according to Cicero, imposed a more stringent causation requirement. Specifically, Cicero said that in addition to requiring that the government would not have paid the claim but for the false statement, Hibbs effectively held that the "subject matter of the false statement . . . be the source of the government's loss." 957 F.2d at 1373 (citing Hibbs, 568 F.2d at 349, 351). We need not decide either whether Hibbs should be read as imposing such a requirement, or whether Hibbs is consistent with the changes made in the False Claims Act since that decision. We think it suffices to point out that both standards can be satisfied: as we concluded in our discussion of damages, Cantekin has presented evidence that Bluestone's grant might not have been approved but for his false statements about his industry funding (or that the grant would have been approved with additional restrictions or requirements). And the content of Bluestone's omissions about his industry funding could have made the difference in whether his grant was approved or not, so even under the Seventh Circuit's reading of Hibbs, the "subject matter of the false statement" could have been the source of the government's loss.

For the foregoing reasons, we will affirm the order of the District Court dated February 9, 1998 and reverse the order dated September 4, 1998. Each party to bear its own costs. CONCUR: STAPLETON, Circuit Judge, concurring: Because, in my view, (1) the uncontradicted evidence establishes that responsible government employees knew of the private funding and alleged conflict of interest prior to the effective date of the Grassley Amendments; (2) the instructions to applicants are clear and unambiguous on their face; and (3) Dr. Cantekin's affidavit alone establishes a dispute of fact as to whether Dr. Bluestone knowingly submitted false claims, I join the judgment of the Court.
