FOLLOW the MONEY, Part II
Recently we looked at some financial aspects of the boundary between Stanford University and Corcept Therapeutics. Dr. Alan Schatzberg, the chair of Stanford’s psychiatry department, received at least $510,000 from Corcept between 2000 and 2007. Senator Grassley asked why NIH received no disclosure from Stanford of Dr. Schatzberg’s realized gain from selling Corcept stock while he was Principal Investigator on a related NIH grant. The Senator also remarked on Stanford’s lowball estimate to him of Dr. Schatzberg’s equity in Corcept, currently between $5 million and $6 million.
Dr. Schatzberg is not the only academic to benefit from Corcept. Dr. Charles Nemeroff, a member of Corcept’s scientific advisory board, also did well. He exercised options to buy 60,000 shares on joining the board in 1998. Dr. Nemeroff diligently promoted Corcept’s drug. Following the style documented for Dr. Schatzberg, Dr. Nemeroff emphasized weak positive trends in the data while suppressing inconvenient negative analyses. In the fall of 2002, Dr. Nemeroff referred to the Stanford-NIH trials as “impressive studies indicating that ... (mifepristone)...is very effective in the treatment of psychotic depression.” The claims “impressive” and “very effective” are indefensible, and may even be fraudulent. Dr. Nemeroff’s exaggerated promotion occurred while the company prepared for its IPO, but he did not disclose his financial stake. Right after the 6-month SEC-mandated lockup period expired, Dr. Nemeroff sold 20,000 shares for $137,500. His cost was $6.60. Help me, what is the right term for this behavior?
A second member of the team who did well is Dr. Joseph Belanoff, Corcept’s co-founder and CEO. Like Dr. Schatzberg, he received around 3 million shares in 1998. Dr. Belanoff began selling as soon as the lock-up period ended. Between November 2004 and November 2006, Dr. Belanoff sold approximately 10,000 Corcept shares each month, realizing over $1 million. His cost for all those shares was around $80. An on-line financial service listed 6 additional quarterly sales, each of 30,000 shares, which netted over $900,000. Dr. Belanoff also received an ample corporate salary. His documented salary increased from $310,500 plus a 10% bonus in 2003 to $1,643,760 in salary ($411,008), bonus ($102,752), and stock options ($1,130,000) in 2007. Not bad, for someone with modest academic credentials.
Stanford University itself has a financial stake. Following a licensing fee of $47,000 that was paid to Stanford in 1999 along with 30,000 shares of stock, Corcept has been obligated to make non-refundable royalty payments of $50,000 a year. That adds up to $497,000 through 2008. Additional payments up to $250,000 are due to Stanford when certain drug development milestones are reached. Stanford has stated that it long ago divested itself of the Corcept stock. However, an on-line information service lists Stanford as a major shareholder as recently as 31 March 2008, with over 47,000 shares in the name of the Board of Trustees. In a second agreement, Stanford receives a $20,000 licensing fee, 1000 shares of Corcept stock, $10,000 a year in non-refundable royalties, and potential milestone payments of $350,000. All of this is in advance of any marketing of products by Corcept. So, Stanford is not exactly a disinterested administrator of the academic-corporate boundary between Dr. Schatzberg, NIH, and Corcept.
We should also note some unusual events involving Corcept stock movements. On 15 August 2005 Corcept stock received a research broker upgrade. Heavy selling followed the upgrade (volume was 613,000 shares, 31 standard deviations above the mean for the previous 10 trading days). For non-statistician readers, 3 standard deviations would tell us that the spike is almost certainly not consistent with the historical fluctuations in volume. So, a spike of 31 standard deviations means any such probability is astronomically small. The stock price moved up 34% from the previous day but quickly sank again. That same day, Dr. Schatzberg sold 15,597 shares for $109,179, at an intra-day high of $7 per share. The cost basis of those shares to him was $5.15.
On Friday 23 September 2005, heavy selling of Corcept stock occurred (871,700 shares). This volume was 35 standard deviations above the mean of the previous 10 trading days. On the following Monday, Corcept announced that a widely publicized study of mifepristone for Alzheimer disease was being halted prematurely for lack of progress. The company also announced slower than expected enrollment in a Phase III study of psychotic depression, for which they projected delayed announcement of results. Over the next month the stock price declined 16%.
These episodes of concentrated stock movement represent coincidences that remain to be explained. Was the August 2005 upgrade and selling spike in which Dr. Schatzberg participated a case of “pump and dump”? Was the September 2005 selling spike ahead of bad news a case of insider trading? Who did all that selling, and how did they know?
The questions just keep coming.

MANAGING CONFLICTS of INTEREST at STANFORD
MANAGING CONFLICTS OF INTEREST AT STANFORD
The case of Stanford University and Dr. Alan Schatzberg, chairman of Stanford’s department of psychiatry, continues to raise questions. You can see previous discussions here. The questions concern transparency at the academic-corporate boundary, reporting conflicts of interest to NIH, and Stanford’s “management” of a faculty member known to have a significant conflict. The conflict involves a company Dr. Schatzberg founded (Corcept Therapeutics), a drug called mifepristone that Corcept has in clinical trials for depression, and NIH-supported studies of the same drug at Stanford.
Stanford’s position is that Dr. Schatzberg “has not been involved in managing or conducting any human subjects research involving Mifepristone …” Dr. Schatzberg’s 2006 published disclaimer stated “…Dr Schatzberg played no direct role in the recruitment, assessment, or follow-up of subjects enrolled in this study. Dr Schatzberg was not directly involved in the analysis of data stemming from this research.” Stanford represented that this disclaimer applies also to earlier publications with Dr. Schatzberg as co-author.
This disclaimer is hardly credible, considering the responsibilities of NIH-funded Principal Investigators. I pointed out many of the inconsistencies before. Now there is new evidence that Dr. Schatzberg failed to maintain an arm’s-length relationship to the projects at Stanford.
In a 2008 review article, Dr. Schatzberg discussed the Stanford projects in ways that contradict the claim of an arm’s-length relationship. This article acknowledged Dr. Schatzberg’s NIH grant support at Stanford. Corcept Therapeutics was not acknowledged as a source of funding. The first concern is that, if Dr. Schatzberg’s relationship to the Stanford studies is as Stanford claimed, then he has no business publishing a NIH-supported review article that portrays his drug’s prospects in a favorable light. Hello! Is there a conflict of interest here? Review articles that assess a field and synthesize data form a crucial part of science that has to be off-limits to Dr. Schatzberg just as much as assessing patients in one of his clinical trials would be. His many favorable, even exaggerated, articles, reviews and commentaries since he founded Corcept should have come under this proscription. So much for Stanford’s “management” of the conflict. Dr. Schatzberg certainly had a role in managing the research supported by NIH at Stanford – he managed the climate of scientific opinion for his drug and he managed the tone of the NIH-supported publications from Stanford.
Second, Dr. Schatzberg made a claim of efficacy for his drug that differed from what was originally reported in an NIH-supported Stanford study. He claimed a 31% decrease of symptom ratings with a scale called the BPRS. The original report does not confirm that claim. From the published data tabulated in the report, the reduction of symptom severity was 20%. Readers can easily check that for themselves. So, in a current scientific review article Dr. Schatzberg deviated from the published record. He also inflated by half the efficacy estimate for his drug. Hello! Is there a conflict of interest here?
Third, this false claim indicates that Dr. Schatzberg performed and published his own reanalysis of the primary data from an NIH-funded Stanford study. He didn’t get the number 31% from the published article. Yet Stanford says he had no part in managing or conducting the research or in analyzing any data. So here we have an NIH-funded Principal Investigator, with a clear conflict of interest, who supposedly remains at arm’s length from the project, accessing the primary data files, running a new analysis himself, and publishing an exaggerated new efficacy result for his drug that does not match what he published previously as a co-author. That is inconsistent with Stanford’s defense of Dr. Schatzberg. Hello! Is there a conflict of interest here?
Fourth, in this review article Dr. Schatzberg presented the first data on mifepristone blood levels in a peer reviewed journal, along with an elaborate scientific argument for the importance of the blood level as a moderator of response. These blood level data came from Corcept’s clinical trials, but the target blood level stated by Dr. Schatzberg did not correspond to SEC filings and press releases from Corcept. The administrative issue here is how Stanford justifies the presentation and discussion of original scientific data by a Principal Investigator who is supposedly insulated from the scientific work of the project in order to avoid bias. Dr. Schatzberg’s discussion of the new data and his scientific arguments about blood levels form a crucial part of the scientific platform for his drug’s current prospects, and as such must be off limits, just as assessing patients in one of his clinical trials would be off limits under Stanford’s policy. Hello! Is there a conflict of interest here?
This current example undercuts the assertions by Stanford and Dr. Schatzberg that his conflicts of interest have been “managed” by the University. Dr. Schatzberg may not have assessed any patients in Stanford’s trials of mifepristone, but he has had the lead role in responding to scientific critiques, where he clearly was the manager. He also has had the lead role in selling the mifepristone story to the scientific community and in shaping the tone of the NIH-supported Stanford publications that Corcept relied on to raise capital. Hello! Is there a conflict of interest here? How does Stanford justify these academic-commercial boundary violations, and why does NIH not act on the known conflicts of interest? That was Senator Grassley’s question to Dr. Zerhouni today.

STANFORD, SCHATZBERG and CORCEPT THERAPEUTICS: RECOGNIZING and MANAGING CONFLICTS
STANFORD, SCHATZBERG and CORCEPT THERAPEUTICS: RECOGNIZING and MANAGING CONFLICTS
The case of Stanford University and Dr. Alan Schatzberg, chairman of Stanford’s department of psychiatry, has been in the news for a week. Senator Grassley raised concerns about conflicts of interest, reporting of same, and Stanford’s policies. In play are a company called Corcept Therapeutics that Dr. Schatzberg founded, and a drug called Mifepristone or RU 486 that is in clinical trials for a severe form of depression. Interest in this case is especially high because Dr. Schatzberg is the president-elect of the American Psychiatric Association. Daniel Carlat, Clin Psych, and University Diaries have had cogent commentaries on the wider implications of this breaking issue.
The University issued a statement in response to Sen. Grassley. This statement asserted that Dr. Schatzberg has fully complied with the University’s rigorous conflict of interest policy and that Dr. Schatzberg “has not been involved in managing or conducting any human subjects research involving Mifepristone, a pharmaceutical that Corcept licenses for the treatment of psychotic major depression.”
Stanford’s account of Dr. Schatzberg’s arm’s-length role in Stanford’s NIH-supported studies of RU 486 (mifepristone) for depression is questionable, if not disingenuous. Dr. Schatzberg’s patent application filing for use of RU 486 in depression occurred in 1997, and he founded the corporation Corcept Therapeutics in 1998. He was a member of the board of directors from 1998 to 2007. He has chaired the corporation’s scientific advisory board since 1998.
There is reason to believe that Dr. Schatzberg had a key role in Stanford’s clinical trials of Corcept’s drug reported in 2001, 2002, and 2006. He was a co-author on all three publications, and there was no disclaimer about his role until 2006. This disclaimer is hardly credible. As Principal Investigator on the NIH grants, Dr. Schatzberg was expected to supervise the junior faculty and research staff at Stanford who recruited, assessed, and treated patients in the studies of RU 486. He was responsible for the choice of outcome measures, about which questions have been raised. He was responsible for the quality of the reported data analyses, which were, frankly, inexpert, when they were provided at all. Above all, he was responsible for the tone of the NIH-supported Stanford publications that claimed Corcept’s drug is effective.
If there were any doubt that Dr. Schatzberg’s hands were all over these Stanford studies, one only has to see the record of his leading role in responding to scientific critiques of their design, execution, analysis, and interpretation. He was clearly the manager.
Moreover, the record is clear that Corcept relied on the NIH-supported Stanford publications for positive claims to enable the corporation to raise capital (well over $100 million by now, with nothing to show for it). Corcept’s own Phase III clinical trials have been uniformly negative. For this strategy to succeed, the Stanford trials had to be portrayed as positive. As Paul Jacobs detailed in the San Jose Mercury News in 2006, using independent statistical experts, Dr. Schatzberg and his Stanford/Corcept colleagues made seriously exaggerated claims for the drug’s efficacy in their 2001 and 2002 publications. These exaggerated claims have been assiduously repeated by Dr. Schatzberg, by Stanford faculty members answerable to him, and by academic members of Corcept’s scientific advisory board in many scientific journals and textbooks. All these testimonials are compromised. The effect of these repeated, unjustified, claims is to raise the profile of the corporation and of the drug. It amounts to public relations and branding through academic outlets. Roy Poses on this site has dissected the scientific credibility of claims for the utility of RU 486 in depression.
Far from being removed from the scientific debate about Corcept’s drug, Dr. Schatzberg has had the leading role in “selling” the story to the scientific community, in “defending the brand” against scientific criticisms, and in providing his corporation a plausible story line to attract new capital. It was Dr. Schatzberg who talked about how the drug “may be the equivalent of shock treatments in a pill” in a 2002 Stanford press release. There is no clear boundary between Dr. Schatzberg’s NIH-supported academic roles and his service to the corporation he founded. As for not being involved in the management of the Stanford projects, Dr. Schatzberg acknowledged to Paul Jacobs of the San Jose Mercury News “that he has considerable influence over the junior faculty members doing the studies. As chairman of psychiatry, he helps set their salaries and can affect their career advancement. And he continues as a co-author of the resulting papers.”
I have already commented on Dr. Schatzberg’s efforts to sell large parcels of Corcept stock during the company’s IPO attempts. Had these efforts been successful, Dr. Schatzberg would have benefited by $7-11 million, while still retaining over 2 million shares of Corcept stock. This aspect of the issue troubles many people. In our capitalist system, considered so necessary for developing innovative drugs, nobody complains when an entrepreneur makes a fortune inventing a useful product. Dr. Schatzberg’s apparent intent, however, was to reach for the reward before contributing any product of redeeming social value. The prospects of RU 486 succeeding as a useful treatment of psychotic depression are close to zero. People view such behavior as gaming the system. Moreover, under Stanford’s existing rules, these projected stock sales might never have been reported.
Are these significant conflicts of interest? Yes. Have they “influence(d) the conduct of medical research” at Stanford (quoting now from Stanford’s June 24 statement)? Yes. Dr. Schatzberg’s NIH grants dovetail with the efforts of his corporation, and the corporation used data from the NIH-grant-supported projects for commercial promotion. Had the corporation not existed, these particular grants likely would not have been initiated or would have had different scientific emphases. Has Dr. Schatzberg’s research “been compromised by his financial stake”? Yes. His academic publications on depression and RU 486 are compromised by exaggerated and self-serving claims for his corporation’s drug. Senator Grassley is right: it is time for Stanford to get real about corporate-academic boundaries.

IS THERE A BASIC SCIENTIST ON THE BENCH?
One of the innovations in stealth infomercials that pharma has developed is the basic science play. Here’s how it works, illustrated in masterly style by the good people at Corcept Therapeutics.
Since 2001, Corcept has been touting a drug called mifepristone (that’s right, RU486) for treatment of patients with psychotic major depression (PMD). The drug blocks cortisol receptors, and high cortisol was theorized to be a cause of the delusions and hallucinations experienced by patients with PMD.
Corcept got fast track approval for their drug from the FDA on the somewhat specious ground that there are no FDA-approved treatments for PMD. They have published a series of small clinical trials that had negative outcomes. One tiny study (N = 5) had no statistically significant result. A second study of 30 patients had no statistical analyses whatsoever. In another study of 30 patients, the statistical analysis was incorrect. These failures did not stop the Corcept team from talking up the drug’s potential in review articles, book chapters, Continuing Medical Education programs, news reports, and press releases. In quite a few of these promotional “product placements,” the financial ties of the authors with the company were not disclosed.
All that is pretty much par for the course in the academic-industrial complex: clinical key opinion leaders were bought and paid for long ago. Now comes the basic science play. In the August 2006 issue of Journal of Neuroendocrinology, a report describes how Corcept’s drug can reverse the deleterious effect of high glucocorticoid levels on neurogenesis in the hippocampus of rats (1). This finding ties in with some inconclusive evidence that some patients with depression may have reduced hippocampal volume. So, this new basic finding is potentially a big deal for Corcept. Indeed, Corcept provided funding for the study. One fully expects that the company will highlight this new information in future statements.
Looking at the new report, one sees in the Acknowledgements that the first author was supported by Corcept. One also sees that a co-author, E. Ronald de Kloet, failed to disclose his relationship to the company: he is a member of Corcept’s scientific advisory board and, unless he has sold any, the owner of 60,000 shares of Corcept stock. One also sees that this basic science article is careful to follow the company’s marketing message and branding language on the putative efficacy of mifepristone for PMD. For instance, it states, “The glucocorticoid receptor antagonist mifepristone has been shown to rapidly and effectively ameliorate symptoms of psychotic major depression.” These basic scientists also stated, “recent clinical studies have shown that the glucocorticoid-receptor (GR) antagonist mifepristone relieves symptoms of psychotic depression after a remarkably brief treatment period of 4 or 8 days.” None of the cited studies shows anything of the sort. We then read, “… similarly to its clinical efficacy, mifepristone’s effects on adult neurogenesis are rapid and positive, and may therefore be important for its mechanism of action.”
What’s going on here? Could it be that one of Corcept’s basic science consultants has been pulled off the bench to pinch hit for the company? The usual readership of Journal of Neuroendocrinology will know nothing about the clinical trials of the drug and will accept at face value the exaggerated statements of mifepristone’s efficacy in PMD. And now the clinical spokespeople for Corcept can point to a new piece of basic science “validation” of their product. Look for it to be highlighted in the next round of book chapters, review articles in clinical journals, CME events, and press releases.
The company needs pinch hitters right now because they have recently had to announce that two large Phase III trials failed. The house of cards is collapsing: they have been informed by NASDAQ that the company is in danger of being delisted because the share price has gone from $12 at issue in April 2004 to around 80 cents today. All in all, Corcept is a case study in bad outcomes for academic entrepreneurs and their backers. Many investors have been burned. Worse, after going through around $95 million of venture capital and IPO proceeds, not to mention several million dollars of NIMH funding, they have failed to answer the original question: does mifepristone help seriously ill patients with PMD accompanied by elevated cortisol production? Now, as the company enters what may be its final spasm of activity, comes this new corruption of the basic medical science literature.
We have long known that citations of the medical literature are not holy writ, but now they are becoming advertising copy. As George Winokur, former chair of psychiatry at the University of Iowa, liked to joke, the medical literature is like the Bible: people can find in it whatever they are looking for. Some of us learned in our training that when we cite an article in one of our manuscripts, we need to actually read that article, understand its methods, and agree with its conclusions. Had the authors of this stealth infomercial in Journal of Neuroendocrinology scrutinized the clinical trials reports that they cited, even as basic scientists they would have recognized the weakness of the evidence. Thus does the corporate mandate to put lipstick on the pig vitiate even the basic medical science literature.

Since 2001, Corcept has been touting a drug called mifepristone (that’s right, RU486) for treatment of patients with psychotic major depression (PMD). The drug blocks cortisol receptors, and high cortisol was theorized to be a cause of the delusions and hallucinations experienced by patients with PMD.
Corcept got fast track approval for their drug from the FDA on the somewhat specious ground that there are no FDA-approved treatments for PMD. They have published a series of small clinical trials that had negative outcomes. One tiny study (N = 5) had no statistically significant result. A second study of 30 patients had no statistical analyses whatsoever. In another study of 30 patients, the statistical analysis was incorrect. These failures did not stop the Corcept team from talking up the drug’s potential in review articles, book chapters, Continuing Medical Education programs, news reports, and press releases. In quite a few of these promotional “product placements,” the financial ties of the authors with the company were not disclosed.
All that is pretty much par for the course in the academic-industrial complex: clinical key opinion leaders were bought and paid for long ago. Now comes the basic science play. In the August 2006 issue of Journal of Neuroendocrinology, a report describes how Corcept’s drug can reverse the deleterious effect of high glucocorticoid levels on neurogenesis in the hippocampus of rats (1). This finding ties in with some inconclusive evidence that some patients with depression may have reduced hippocampal volume. So, this new basic finding is potentially a big deal for Corcept. Indeed, Corcept provided funding for the study. One fully expects that the company will highlight this new information in future statements.
Looking at the new report, one sees in the Acknowledgements that the first author was supported by Corcept. One also sees that a co-author, E. Ronald de Kloet, failed to disclose his relationship to the company: he is a member of Corcept’s scientific advisory board and, unless he has sold any, the owner of 60,000 shares of Corcept stock. One also sees that this basic science article is careful to follow the company’s marketing message and branding language on the putative efficacy of mifepristone for PMD. For instance, it states, “The glucocorticoid receptor antagonist mifepristone has been shown to rapidly and effectively ameliorate symptoms of psychotic major depression.” These basic scientists also stated, “recent clinical studies have shown that the glucocorticoid-receptor (GR) antagonist mifepristone relieves symptoms of psychotic depression after a remarkably brief treatment period of 4 or 8 days.” None of the cited studies shows anything of the sort. We then read, “… similarly to its clinical efficacy, mifepristone’s effects on adult neurogenesis are rapid and positive, and may therefore be important for its mechanism of action.”
What’s going on here? Could it be that one of Corcept’s basic science consultants has been pulled off the bench to pinch hit for the company? The usual readership of Journal of Neuroendocrinology will know nothing about the clinical trials of the drug and will accept at face value the exaggerated statements of mifepristone’s efficacy in PMD. And now the clinical spokespeople for Corcept can point to a new piece of basic science “validation” of their product. Look for it to be highlighted in the next round of book chapters, review articles in clinical journals, CME events, and press releases.
The company needs pinch hitters right now because they have recently had to announce that two large Phase III trials failed. The house of cards is collapsing: they have been informed by NASDAQ that the company is in danger of being delisted because the share price has gone from $12 at issue in April 2004 to around 80 cents today. All in all, Corcept is a case study in bad outcomes for academic entrepreneurs and their backers. Many investors have been burned. Worse, after going through around $95 million of venture capital and IPO proceeds, not to mention several million dollars of NIMH funding, they have failed to answer the original question: does mifepristone help seriously ill patients with PMD accompanied by elevated cortisol production? Now, as the company enters what may be its final spasm of activity, comes this new corruption of the basic medical science literature.
We have long known that citations of the medical literature are not holy writ, but now they are becoming advertising copy. As George Winokur, former chair of psychiatry at the University of Iowa, liked to joke, the medical literature is like the Bible: people can find in it whatever they are looking for. Some of us learned in our training that when we cite an article in one of our manuscripts, we need to actually read that article, understand its methods, and agree with its conclusions. Had the authors of this stealth infomercial in Journal of Neuroendocrinology scrutinized the clinical trials reports that they cited, even as basic scientists they would have recognized the weakness of the evidence. Thus does the corporate mandate to put lipstick on the pig vitiate even the basic medical science literature.
