CASE 8.8 – MERCK AND VIOXX
Use PowerPoint Slide 306 as a backdrop (evolving regulatory cycle) for discussing the case.
In gaining perspective on this case, review the following memo offered from a consultant on the situation

RE What Went Wrong With Vioxx and Necessary Changes in Merck Culture
DATE September 4, 2006
Based on a review of company records, FDA interactions, and discovery documents in the ongoing Vioxx
litigation as well as interviews with management and Merck employees, we offer the following insights
and recommendations for Merck. Both cultural characteristics and process issues contributed to the loss
of this important drug as a Merck product.
Candor
Our review indicates that there were several critical points in the Vioxx approval and sales periods when
candor suffered. For example, during the Phase 3 FDA process, Dr. Reicin’s e-mail expresses concerns
about negative findings, but also reflects a fear of sharing that information with management. The failure
of this information to percolate to managers and others responsible for FDA interaction resulted in a
less-than-candid report to the FDA. The board is aware of the consequences of this omission in terms of
regulatory relationships as well as ongoing investigations by several federal agencies. This lack of
candor continued when the Cleveland studies were released. There was no public disclosure of warnings
regarding the studies. In fact, the studies were used to promote Vioxx as “heart friendly.” The disclosures
on both the product and to physicians were minimal and did not reflect the rising body of evidence
accumulating regarding Vioxx and CVE. The safety committee withheld its initial findings as well. Finally,
the withdrawal of Dr. Cannuscio’s name from the Circulation article was not just a misstep in terms of
candor. This withdrawal had implications in terms of public perception as well as for Merck employees
and the company’s desire to understand issues and the expectations regarding candid discussions.
Decision Analysis
Hindsight does carry the benefit of clear and global views. However, there are some flaws in the Merck
decision processes that require change. Scientists who were examining the studies and data for Merck
were not in error in their conclusions about past experience or statistical insignificance. However, the
lessons of Vioxx, as with the lessons of other companies such as Johns-Manville and asbestos,
Jack-in-the-Box and e-coli, and McNeil and Tylenol (cases that will be used as examples in our
presentation) are that there is an extremely low tolerance for risk where human life is at issue. Joan
Wainwright’s response to the press on the 2004 minutes of the scientists’ meeting was, “Those
percentages are based on very small numbers of events.” She is correct, but perception is critical,
particularly in pharmaceutical cases. Merck scientists believe (and rightly so) that no drug can be made
risk-free. However, the issue is not one of making the drug risk-free, but is rather a more complex two-art
decision of what to disclose in terms of potential risks and when to disclose it. The marking points in
candor were also critical decision points at which time scientists, along with managers, should have
evaluated the costs and benefits of continuing with the status quo.
The flaw in the decision process appears to have rested with limited views of costs and risks and
overemphasis on benefits. Vioxx sales were $2.5 billion (representing 18% of net income and 11% of
revenue) and significant pressures perhaps created a dependence on achieving those numbers. Analysts
were increasingly negative about Merck because of a lack of a pipeline of drugs and perceived lack of
innovation. The immediate success, low margins, and high returns served to increase the pressure to
keep what was called Merck’s “big hit” going. However, those who decided to continue selling the drug
without additional warnings and disclosures failed to assess the risk when the information surfaced.
