Merck Provides Update on Next Steps for TREDAPTIVE™ (extended-release niacin/laropiprant)

  Merck Provides Update on Next Steps for TREDAPTIVE™ (extended-release

Business Wire

WHITEHOUSE STATION, N.J. -- January 11, 2013

Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today
announced the company is taking steps to suspend the availability of
TREDAPTIVE^™ (extended-release niacin/laropiprant) tablets worldwide.
TREDAPTIVE is not approved for use in the United States.

Merck is taking these steps based on the current understanding of the
preliminary data from the HPS2-THRIVE (Heart Protection Study 2-Treatment of
HDL to Reduce the Incidence of Vascular Events) study, and in consultation
with regulatory authorities. As previously reported by Merck (Dec. 20, 2012
news release), HPS2-THRIVE did not achieve its primary endpoint of reduction
of major vascular events, and there was a statistically significant increase
in the incidence of some types of non-fatal serious adverse events in the
group that received TREDAPTIVE compared to statin therapy. The decision to
suspend availability of the medicine is aligned with the recommendation of the
European Medicine Agency’s Pharmacovigilance Risk Assessment Committee (PRAC)
based on the trial’s results.

In countries where the medicine is currently available, Merck has begun
informing regulatory agencies of the company’s decision. Merck is working with
these agencies to develop communications for health care providers and to
suspend the availability of TREDAPTIVE, with the timing to be based on
individual country regulations and processes.

Merck is recommending that physicians stop prescribing TREDAPTIVE. Merck is
also recommending that physicians review treatment plans for patients taking
TREDAPTIVE in a timely manner to discontinue TREDAPTIVE and consider other
changes in therapy to achieve their dyslipidemia management goals. In the
meantime, Merck encourages patients with questions to speak with their health
care provider, and to not discontinue therapy without first speaking with
their physician.

“Patients currently taking TREDAPTIVE are our priority, and we are committed
to continue to work with regulatory agencies around the world to ensure that
physicians have appropriate information as we take steps to suspend the
availability of TREDAPTIVE,” said Michael Rosenblatt, M.D., Chief Medical
Officer, Merck.

About the HPS 2-THRIVE Study

HPS2-THRIVE was independently conducted by the Clinical Trial Service Unit at
Oxford University and funded by Merck. With the agreement of the independent
research team at Oxford University, Merck is sharing results from the study
with regulatory agencies. The investigators are conducting additional analyses
to further understand the results. They anticipate reporting the detailed
study results in the first quarter of 2013.

The study enrolled 25,673 patients considered to be at high risk for
cardiovascular events. Of those enrolled, 14,741 were from Europe (the United
Kingdom and Scandinavia) and 10,932 were from China. Patients in the study
were followed for a median of 3.9 years. HPS2-THRIVE compared extended release
niacin and laropiprant plus statin therapy versus statin therapy. It was not
designed to assess directly the separate effects of either extended-release
niacin or laropiprant.

In the study, adding the combination of extended-release niacin and
laropiprant to statin therapy did not significantly further reduce the risk of
the combination of coronary deaths, nonfatal heart attacks, strokes or
revascularizations compared to statin therapy. In addition, there was a
statistically significant increase in the incidence of some types of non-fatal
serious adverse events in the group that received extended-release

Preliminary analyses suggest that the adverse events fall within the following
broad categories: blood and lymphatic, gastrointestinal, infections,
metabolism, musculoskeletal, respiratory and skin. Additional analyses are
ongoing to understand the adverse events within these categories.

TREDAPTIVE has been approved in approximately 70 countries, including in
Europe, and is sold in approximately 40 countries. TREDAPTIVE is also sold
under the brand names PELZONT in Italy and TREVACLYN in Italy and Portugal and
CORDAPTIVE in other markets around the world. Sales through the first three
quarters of 2012 were approximately $13 million.
