Massive 98-Page Consolidated Amended Complaint Filed Today in Polk, et al. v. Schering Plough, et al.

In much the same vein that the ENHANCE Securities Fraud Amended Complaint broke new legal ground, so too, does today’s In Re Vytorin/Zetia Marketing, Sales Practices and Products Liability Litigation (MDL 1938) complaint. Significantly, it recites information clearly obtained from the very same “confidential witnesses” in the ENHANCE securities fraud suit — but, again, refrains from specifically identifying them. I am certain these various camps are paying close attention to, and cribbing from, one anothers’ filings — and quite wisely so.

The other new wrinkle here, is the newly-added detail, and fine-patina, on the various mechanisms Schering’s upper management used to (allegedly) supress the ENHANCE results for almost 24 months. And again, Mr. Hassan’s, and Ms. Cox’s names are prominently associated with these efforts — efforts to negate, or delay, the ENHANCE results. All allegedly. Ahem.

I will have more on this tomorrow, but let’s dive right in — at pages 30 to 35, Paragraphs 72 through 97 (and 110) of the newly-filed complaint. I’ll likely put up a link to the full PDF file, tomorrow.

. . . .Defendants Initiate a Scheme To Suppress the ENHANCE Study Results

72. In response to these results, Defendants immediately delayed public release of the information. In June 2006, a Schering-Plough executive told investors that the ENHANCE data would be ready by the end of 2006, meaning that the results of the study would not be announced, as originally planned, at the American College of Cardiology meeting that fall. At the time, this postponement received little notice in the medical community, since drug studies
frequently are not released on schedule.

73. However, Defendants did not withhold announcement of the ENHANCE results because of ordinary delays in producing a drug study. They delayed because upper management at Schering-Plough already knew that “they were not going to get any good news” from ENHANCE. A former Senior Medical Director in Schering-Plough’s Cardiovascular group, who worked with Schering-Plough’s “Brand Team” during the time that the ENHANCE data was being gathered and finalized, has advised that Schering-P lough performed quality control assessments of the ENHANCE data in late 2005 and 2006. Updates on the progress of the ENHANCE study were shared at the quarterly Brand Review Meetings led by Carrie Cox, Schering-Plough’s Executive Vice President and President of Global Pharmaceuticals.

74. Dr. Kastelein, ENHANCE’s primary investigator, was prepared to publish ENHANCE’s results in early 2007 and present them at the meeting of the American College of Cardiologists in the Spring. However, Defendants sought to further delay publishing the results, in order to find a way to either negate or mitigate the findings of the ENHANCE study.

75. As part of their scheme, in January 2007, Merck and Schering-Plough, through MSP, hired Dr. Michiel L. Bots, M.D., Ph.D., Associate Professor of Epidemiology at the Julius Center for Health Services and Primary Care of the University Medical Center of Utrecht in the Netherlands, as an “independent consultant.” Defendants asked Dr. Bots to advise them about, and to write a report detailing, purported problems with ENHANCE’s CA IMT measurements.

76. Dr. Bots provided Merck and Schering-Plough his report on or about January 26, 2007. The plan to use Dr. Bots to undermine the ENHANCE study results had backfired. He found no problems with ENHANCE data that justified any delay in releasing the study’s results.

77. According to the Bots Report, Merck and Schering-Plough set up three meetings in Amsterdam at the Core Echo Laboratory, where the image database was housed, to address the companies’ purported concerns – one meeting on January 16, 2007 and two on January 18, 2007. The Bots Report defined Dr. Bots’s objectives as:

(i) determining if the reading of the ultrasound images had been done according to the pre-established protocols for the study; and

(ii) determining how to address “outliers,” which were large differences in CA IMT
measurements between visits one week apart, which “were beyond what was to be expected from normal progression.”

78. Dr. Bots wrote in his report that at the January 16, 2007 meeting, “the core lab showed how the measurements were done.” Based upon this presentation and his discussions with the ENHANCE study team, Dr. Bots concluded that the CA IMT measurements “were indeed done in a manner that was described in the protocol.” Twice more, Dr. Bots’s report stated that the “CIMT measurements seem to be done according to the procedures outlined in the protocol.” On this issue, Dr. Bots concluded that the “CIMT measurements in ENHANCE have been done in a consistent manner, leading to reproducibility findings that compare well with that of published studies from other multi-centre randomized trials.”

79. On the purported “outliers” issue, Dr. Bots again found no problems with the ENHANCE data. Dr. Bots stated that the “core lab has re-evaluated all the images of the visits 3-4 [the first two measurement visits] that had a CIMT value that was 50% or more different” and re-evaluated similar images from visits 13-14 (the last two measurement visits). However, with respect to the “mean absolute CIMT difference and the standard deviations,” Dr. Bots concluded that “data are well in line with the studies that have been published in the literature. Based on those findings there seems to be little concern regarding the validity and precision of the data.”

80. Analyzing “how the reproducibility based on the original data changed when the ‘corrected’ outlier data were used,” Dr. Bots found that “[t]his improved . . . the standard deviation of the mean differences” but “the improvement was very modest.” Dr. Bots concluded that the “variability due to imaging and reading” was “excellent” and that the statistician’s concerns about results were “beyond biological variation.” In short, Dr. Bots found no reason to question the ENHANCE trial’s data.

81. The Bots Report addressed the issue of missing data: “Of the common carotid segment CIMT was missing for 4% of the participants, for the bifurcation segment 12% and for the internal segment 12%.” While “[m]issingness may affect the CIMT value,” Dr. Bots concluded that these figures were “in line with observational studies” and that “the current statistical models that were used in the analysis of CIMT trial data do appear to take care of that in an adequate manner.” Dr. Bots further rejected any concerns, saying:

Since the study was blinded, and the sonographer can not identify which participants were “progressors” and which participants are “regressers,” the effect of missing imaging information is likely to be a random phenomenon.

82. Dr. Bots concluded that all of the supposed issues with ENHANCE’s data that Defendants raised after the fact amounted to nothing.

83. The “Conclusions” section of Dr. Bots’s Report summarizes that “the evidence to me is sufficient to indicate that the data are fine.” In the Report’s “Summary” Dr. Bots likewise stated that “the evidence shown to me is sufficient to indicate that the CIMT data in ENHANCE are fine: i.e., no better, no worse than what has been reported in the literature.”

84. With Dr. Bots’s categorical confirmation of the validity and reliability of the ENHANCE data, Defendants then sought another way to negate the unfavorable study results and to further delay disclosure of the study results.

85. Defendants now suggested changing the way CA IMT was measured through selection of images, or changing the parameters used to define outliers. Dr. Bots refuted these suggestions also, saying they would change nothing:

[It is] [i]mportant . . . to realize that the above mentioned activities might reduce measurement variability to some extent. Since this is expected to involve only a small number of the measurements, the expected effects on variability are likely to be modest. Again, randomization protects against bias in the estimate of the difference between treatment arms.

86. Dr. Bots did not serve Defendants’ purpose, because his Report found no material issues or problems in following the protocols for the ENHANCE trial, taking and recording the CA IMT measurements, dealing with outliers, or addressing missing data. Dr. Bots’s Report supported immediate release of the ENHANCE results, not the delay for which Defendants had hoped Dr. Bots would provide a scientifically plausible pretext.

87. Defendants were aware of the concern surrounding the delay in the release of the ENHANCE study and were already attempting to downplay the importance of the study. For example, at Schering-Plough’s earnings report conference call on April 19, 2007, Tim Anderson, a Prudential Equity analyst, asked Schering-Plough’s new CEO, Fred Hassan, if he was “worried about the outcome of the [ENHANCE] trial,” Mr. Hassan responded by saying, among other things, that “the data analysis is ongoing for the ENHANCE trial,” and that the study “is a surrogate market trial in a very special population with very special doses. There is a much larger trial called the IMPROVE-IT trial which is more of an outcomes trial . . . . [W]e are pretty confident about the overall pattern of data for VYTORIN.”

88. Mr. Hassan did not mention that ENHANCE had demonstrated that Zetia plus simvastatin was no better than simvastatin alone. Mr. Hassan’s qualification that ENHANCE studied only “a very special population with very special doses” and his quick, subject changing jump to discussing other studies and “the overall mix of the data” strongly imply his knowledge of ENHANCE’s bad results and Defendants’ continued scheme to obfuscate and conceal the negative results.

Defendants Further Delay The Release Of The ENHANCE Results

89. After the ENHANCE study was not presented at the American College of Cardiologists meeting in the fall of 2006, the ENHANCE study was rescheduled to be presented at the meeting of the American Heart Association in the fall of 2007. But Defendants also caused that presentation to be cancelled, apparently to Dr. Kastelein’s frustration. On July 6, 2007, in an e-mail5 to Dr. Enrico Veltri, Group Vice President of Global Clinical Development at SPRI, Dr. Kastelein wrote:

Is it correct that SP has decided not to present at AHA, but to await the two other, completely unvalidated endpoints, which analysis is going to take us straight into 2008??!?? If this is true, SP must have taken this decision without even the semblance of decency to consult me as PI of the study. I can tell you if this is the case, our collaboration is over . . . this starts smelling like extending the study for no other then (sic) political reasons and I cannot live with that.

90. Dr. Kastelein communicated with other senior SPRI researchers, asserting no good reason existed to delay disclosing ENHANCE’s results. On July 6, 2007, Dr. Kastelein sent the following email to Schering-Plough’s Dr. John Strony:

Dear John

[I]s it correct that SP has decided not to present at AHA [the American Heart Association conference from November 4-7, 2007], but to await the two other, completely unvalidated, endpoints, which analysis is going to take us straight into 2008 ??!!?? If this is true, SP must have taken this decision without even the semblance of decency to consult me as PI [principal investigator] of the study. I can tell you that if this is the case, our collaboration is over and I will take the appropriate steps to get in touch with the editors of major Journals as well as with the FDA. This starts smelling like extending the publication for no other then [sic] political reasons and I cannot live with that. This is the second day of a long overdue holiday after a terrible year, thank you very much for yet another terrible chapter of this trial.

91. Dr. Strony responded and explained away the delay as follows:

The timeline for the reading of the femorals alone has been a movingtarget [sic]. First it was 8 weeks, then 12, and then 16. This is under the assumption of having 4 readers. However, one of the four has failed qualification and now we are down to three. If all runs smoothly (whichhas [sic] never happened in ENHANCE) we are told it will take 17 weeks for the primary readings. Don’t forget the querying process and clean-up which is still not factored. . .

92. Dr. Kastelein replied to Dr. Strony on July 7, 2007, copying the message to Dr. Enrico Veltri, SPRI’s Group Vice President of Global Clinical Development, Cardiovascular & Metabolic Diseases:

I have been travelling half the globe in the last 6 months to a number of large and important meetings at the strong wish of Merck to chair them or to present ezetimibe data. At every single one of them I was cleared to say that ENHANCE would be presented by me at AHA. There is no reason whatsoever to include femorals; you will be seen as a company that tries to hide something and I will be perceived as being in bed with you

93. Dr. Veltri responded to the July 7, 2007 email. Dr. Veltri tendered still another excuse for delaying disclosure of ENHANCE’s results.

94. Still not satisfied, Dr. Kastelein sent the following e-mail on July 13, 2007:

Dear Rick,

I am glad you took the trouble of providing me with such a long answer. The raging part of my former emails comes from an enormous amount of frustration and a feeling that I have no control whatsoever on anything that relates to ENHANCE. As you know, in my normal state of mind, I am a controlled individual and I am not hard to work with. However, in all my previous experiences as a member of a Steering Committee or as a PI [primary investigator], I felt I was in control. With ENHANCE, that is totally the opposite.

The database is at SP, consultants like Gene Bond are in my opinion impossible to work with and never agree with me, Bo Yang has made several crucial mistakes on the way that cost us 9 months, Eric is a nightmare to work with in terms of organization and I can go on and on. The last example of this “never working with me” is the fact that you have decided to withdraw the abstract. This is not necessary. You could have sent in an empty abstract that as my friends at AHA tell me can be filled with data one week before AHA itself and if you were too late, you simply withdraw it. One phone call to me would have cleared all of this. This is exactly what I have done with Pfizer for the Torcetrapib latebreakers at ACC this year. The data were ready 3 days before ACC.

Also, I am constantly under pressure from Merck to plan all sorts of activities, before, at and after AHA. Because I !! will be the one who have [sic] to stand up and present and defend the data, and I would deeply appreciate being involved again and not just simply at the end of a long decision line.

95. On August 20, 2007, seven months after issuance of Dr. Bots’s Report, and after Dr. Kastelein’s requests to publish the data had been rejected, Dr. Kastelein met with Merck and Schering-Plough executives to discuss releasing the ENHANCE results. Merck and Schering-Plough demanded that the test data be reviewed yet again. Under pressure, Dr. Kastelein agreed to their request to convene an expert panel to further analyze the issues Defendants had invented regarding the data’s reliability.

96. The panel’s members included John Robert Crouse, M.D. of Wake Forest University; James Stein, M.D., of the University of Wisconsin; David Orloff, M.D., of Med Pace, Inc., Cincinnati; Greg Evans, M.S., of Wake Forest University; and Dr. Bots, author of the aforementioned Bots Report.

97. Having extracted Dr. Kastelein’s agreement to the formation of the expert panel, Merck and Schering-Plough continued to stall. They did not convene the independent expert panel until mid-November 2007. . . .

110. Merck’s and Schering-Plough’s effort to manipulate the panel by showing them only the worst slides, and by using highly pejorative descriptions of those slides, creates a substantial inference that Defendants knew the content and ramifications of the ENHANCE results, and the negative impact such facts would have on Defendants’ marketing strategy and market share, long before they disclosed them. . . .

By then, Congress was already investigating the almost two year delay.
