Arthritis drug Vioxx pulled from market

TRENTON, N.J. -- Pharmaceutical giant Merck & Co. is halting worldwide sales of 
its blockbuster arthritis drug Vioxx, once viewed as possibly being able to 
prevent some cancers, because new data from a clinical trial found an increased 
risk of heart attack and stroke. Its stock price plunged more than 26 percent 
as the company said the recall will hurt its earnings. 

Merck said Thursday that data from the trial showed the increased risk of heart 
attack and other cardiovascular complications began 18 months after patients 
started taking Vioxx. About 2 million people worldwide are currently taking 
Vioxx, according to Merck, and a total of 84 million have taken it since it 
came on the market with great fanfare in 1999.

The data comes from a three-year study aimed at showing that Vioxx at a 25 
milligram dose prevents recurrence of polyps in the colon and rectum. Such 
polyps can turn cancerous. The trial was stopped after Merck discovered study 
participants had double the risk of a heart attack, compared to other 
participants taking dummy pills.

Medical experts advised patients to stop taking Vioxx and consult their doctor 
about alternatives, but said patients should not panic because the risk of a 
heart attack was still relatively low.

``It's a disaster for Merck, coming at the worst time,'' said independent 
health care analyst Hemant Shah of HKS & Co. in Warren, N.J.

Vioxx is one of Merck's most important drugs, with $2.5 billion in sales in 
2003 - about 11 percent of the company's $22.49 billion in revenue that year. 
But sales dipped 18 percent in the second quarter of this year to $653 million, 
partly due to increasing concerns about the drug's safety.

``We're taking this action because we believe it best serves the interest of 
patients,'' Ray V. Gilmartin, Merck's chairman, president and chief executive, 
said in a statement.

``Although we believe it would have been possible to continue to market Vioxx 
with labeling that would incorporate these new data, given the availability of 
alternative therapies and the questions raised by the data, we concluded that a 
voluntary withdrawal is the responsible course to take,'' he said.

Merck, the world's third-biggest drug maker, announced the news before the 
stock market opened. In morning trading on the New York Stock Exchange, Merck 
shares plunged $11.98, or more than 26 percent, to $33.09.

Shah said the withdrawal of Vioxx comes ``at a time when they really need to 
get ready for expiration'' of its patent for Zocor, a drug for high cholesterol 
that is Merck's top-selling drug. Zocor loses patent protection early in 2006 
and sales are expected to plunge when generic competition begins. In an effort 
to replace those revenues, Merck recently launched a drug with partner 
Schering-Plough Corp., Vytorin, that combines Zocor and Schering-Plough's Zetia 
to attack cholesterol levels in two complementary ways.

``This makes it almost inevitable for the company to find a merger partner for 
them to continue to grow,'' Shah said.

Merck's announcement stands to benefit rival Pfizer Inc., the world's biggest 
drug maker. The two companies have been battling for market share, with 
Pfizer's Celebrex arthritis drug dominating the market with about $5 billion in 
U.S. sales alone last year. Pfizer shares were up 17 cents to $30.35 in early 
trading on the NYSE.

``I think Celebrex sales are going to significantly increase,'' Shah said.

Vioxx and a successor drug called Arcoxia, approved in some other countries and 
awaiting Food and Drug Administration approval here, are part of a class of 
anti-inflammatory drugs heavily touted by the pharmaceutical industry as being 
more effective and having less side effects, particularly on the 
gastrointestinal system, than older drugs.

Pfizer's Celebrex and its successor drug, Bextra, which already is on the 
market in the United States, also are in that class, called cox-2 inhibitors.

``This has never been the massive innovation which was promoted to be,'' Shah 
said of the drug class. ``In terms of pain relief, these drugs are no better 
than ibuprofen and they cost 10, 15 times more.''

He said it is possible the news, along with some prior reports about heart risk 
and gastrointestinal bleeding linked to the drugs, could push some patients to 
go back to older, cheaper drugs.

Shah also said physicians prefer ibuprofen more than Celebrex and Vioxx 
combined.

The company said the Vioxx recall will slash about 50 cents to 60 cents a share 
from its earnings for the rest of this year. That includes foregone sales, 
writeoffs of inventory held by Merck, customer returns of product previously 
sold and other costs of the pullback. Merck expects foregone fourth quarter 
sales of Vioxx of $700 million to $750 million alone.

Merck, which is based in Whitehouse Station, N.J., had previously been 
expecting 2004 earnings per share of $3.11 to $3.17.

Merck is scheduled to release financial results for the third quarter, which 
ends today, on Oct. 21.
