Duke Scientist Bringing Millions from NIH and Pharma Suspended Over Rhodes Scholar Claims

The New York Times reports that a medical researcher faked claims to being a Rhodes Scholar, and that a major scandal that has erupted.

The scenario is very familiar to readers of Healthcare Renewal, with universities collecting millions from public sources and the pharmaceutical industry, turning a blind eye to credentials discrepancies of faculty "taxpayers", and the public possibly put at risk through faulty research and suspect "reviews":

Duke Scientist Suspended Over Rhodes Scholar Claims
New York Times
July 20, 2010

Duke University School of Medicine has suspended a researcher and stopped patient enrollment in three cancer studies upon learning of reports that the researcher had overstated his academic credentials.

One of the lead investigators on the cancer studies, Dr. Anil Potti, was placed on administrative leave, said Douglas J. Stokke, a spokesman for Duke, while the university investigates allegations that Dr. Potti had falsely claimed that he was a Rhodes scholar.

The controversy erupted late last week after an article published in The Cancer Letter (PDF), a weekly publication for cancer specialists, reported that Dr. Potti, an assistant professor of medicine, had on occasion exaggerated his credentials. (A spokeswoman at Rhodes House at Oxford confirmed on Tuesday that Dr. Potti had not received the scholarship.)

The scientist, Anil Potti, was engaged in cancer clinical trials using questionable and possbily erroneous analytical methods (prediction models).

In addition, several dozen biostatisticians and cancer researchers at Harvard, Princeton, Johns Hopkins and other academic institutions are now questioning the methodology behind the three clinical trials, urging a halt to the Duke studies � two on lung cancer and one on breast cancer � in a letter sent to the director of the National Cancer Institute.

He'd used the fake credentials to get American Cancer Society money:

When questions about Dr. Potti�s credentials became public, the American Cancer Society suspended payments of a five-year, $729,000 grant awarded to Dr. Potti to study the genetics of lung cancer. The society awarded the grant based in part on a r�sum� from the doctor that included the Rhodes honor, said Dr. Otis W. Brawley, the chief medical officer of the cancer society.

According to The Cancer Letter's expos� linked above:

A high-profile cancer genomics researcher at Duke University claimed in multiple grant applications that he had been a Rhodes scholar, when, in fact, the Rhodes Trust states flatly that he was not.

Documents obtained by The Cancer Letter show that in biographies submitted to NIH, Duke oncologist and genomics researcher Anil Potti claimed variously to have won the prestigious scholarship in 1995 or 1996, depending on the version of the biography.

Potti also made the Rhodes claim in an application that resulted in a $729,000 grant from the American Cancer Society. �We don�t have any record that Anil Potti was a Rhodes scholar,� spokesman for the Rhodes Trust said to The Cancer Letter.

Assuming the fabrications are proven, a number of questions arise:

• How can a Duke scientist have gotten away with exaggerated credentials on a CV used in a grant applicationa to NIH, the American Cancer Society, and perhaps other organizations, claiming to be a Rhodes Scholar?
• Did he make similar exaggerations in his application to Duke itself?
• Do the exaggerations made in NIH and/or other federal grant applications constitute a crime, e.g., under Title 18 of U.S. Code, Section 1001 which makes it a federal crime to make a false statement to the government, according to one contributor to The Cancer Letter article?
  
• Will Duke act on fabrications as criminal matters?
  
• What were the Duke grants office and/or credentials-checking staff doing during their working hours?
• Why did this exaggeration come out in The Cancer Letter?
  

Patients may be at risk:

[MD Anderson Cancer Center biostatisticians] Keith Baggerly and Kevin Coombes said they devoted about 1,500 hours to checking Potti�s and Nevins�s work. These efforts�dubbed �forensic bioinformatics��resulted in a paper in the November 2009, issue of the Annals of Applied Statistics.

�Unfortunately, poor documentation can shift from an inconvenience to an active danger when it obscures not just methods but errors,� the paper stated. �Patients in clinical trials are currently being allocated to treatment arms on the basis of these results.�

The two raised questions about Duke�s randomized phase II single-institution trials that used the Nevins and Potti technology to assign patients to treatment (NCT00545948, NCT00509366, and NCT00636441). Baggerly and Coombes argued that these trials �may be putting patients at risk.�

Duke initially suspended but then restarted the trials after an "investigation" by outside scientists. However:

Experts asked by The Cancer Letter to review these [investigation] documents [obtained under the FOIA] noted that Duke deans Cuffe and Kornbluth were inaccurate in their description of the document�s substance and conclusions when they announced completion of the investigation and resumption of the clinical trials earlier this year.

�Having read the committee�s report, we must disagree with Duke�s representation of the committee�s findings,� Baggerly and Coombes said in an email after reviewing the documents released under FOIA. The committee stated that �In our review of the methods � we were unable to identify a place where the statistical methods were described in sufficient detail to independently replicate the findings of the papers,� and further noted that the Duke investigators �really need� to work on �clearly explaining the specific statistical steps used in developing the predictors and the prospective sample assignments."

Duke has apparently now decided to stonewall:

... The Cancer Letter sent an email with questions to Potti, his collaborator Joseph Nevins, and Duke administration officials. The questions focused on the Rhodes claim, but also touched on other apparent discrepancies.

Responding to everyone on the email CC list, including this reporter, Potti wrote: �Sounds like I need to call him to clarify ...... and probably also talk with you all to clarify. I was a nominee..... and several of the others can also be explained. �Anil.�

After that email, Potti and Duke officials didn�t respond to questions seeking details that could substantiate this response. Multiple calls and emails from The Cancer Letter were not acknowledged.

One reason is that this escapade appears to have many twists and turns regarding credentials claimed by their researcher in the past. See the full article published in The Cancer Letter (PDF). The tale is stunning.

Another reason appears to be this:

Genomic research led by the two scientists [Potti and senior collaborator Joseph Nevins] has brought millions of public and private dollars to Duke. The duo�s connections with the industry are considerable. According to a recent disclosure, Potti is a member of the scientific advisory boards of Eli Lilly and Co., GlaxoSmith-Kline, and CancerGuideDx.

This also raises the questions:

• Did Potti misrepresent his credentials to these pharmas?

• Was Nevins aware of these exaggerations himself?
  

Of course this author is familiar with laxity in Duke's management and academics, and their not replying to pointed questions on their failures.

Perhaps at the time of this grant application, Duke personnel were busy checking the credentials of the Duke Lacrosse team, or of academics such as myself, maligned by Duke professors for having a strong sense of ethics. I then found myself "stonewalled" by Duke's President Richard H. Brodhead on the issues.

(See my Jan. 2008 post "A Truly Appalling Lawsuit Against Duke University" for more on that affair.)
