Arena Pharmaceuticals Announces Achievement of Phase 2 Clinical Milestone Under Cardiovascular Disease Collaboration With Merck
SAN DIEGO, May 18, 2006 /PRNewswire-FirstCall via COMTEX News Network/ -- Arena Pharmaceuticals, Inc.
(Nasdaq: ARNA) announced today the initiation of a Phase 2 clinical trial of
MK-0354, an Arena discovered orally administered drug candidate under
development by Merck for the treatment of atherosclerosis and related
disorders. The Phase 2 clinical trial triggers a $4 million milestone payment
to Arena under the research collaboration and license agreement for compounds
targeting a G protein-coupled receptor, or GPCR, that have the potential to
regulate plasma lipid profiles, including HDL, or the "good" cholesterol,
similar to the therapeutic action of niacin.
The Phase 2 clinical trial is a randomized, double-blind,
placebo-controlled study that will further evaluate safety, tolerability and
pharmacokinetics, as well as potential efficacy, of MK-0354 in patients with
The Phase 1 clinical trial program of MK-0354 included two randomized,
double-blind, placebo-controlled studies evaluating the safety, tolerability
and pharmacokinetics of MK-0354 in healthy volunteers. In both studies
MK-0354 was generally well-tolerated at all doses studied.
"We are pleased with Merck's decision to advance MK-0354," said Jack Lief,
President and CEO of Arena. "We look forward to the Phase 2 results and to
the continued advancement of this program."
"Merck is pleased with the progress of this program to date," said
Kathleen Metters, Ph.D., Senior Vice President, Basic Research, Merck Research
Laboratories. "This is another example of Merck's commitment to rapidly
develop novel therapies for the treatment of atherosclerosis."
Atherosclerosis is characterized by the collection of fatty material
deposits, such as cholesterol, along artery walls. This fatty material
thickens, hardens, and may eventually block the arteries, adversely affecting
blood flow and increasing the risk of heart attack and stroke over time.
Atherosclerosis accounts for nearly three out of every four deaths from
cardiovascular disease. In 1999, U.S. community hospitals billed
$26.2 billion for coronary atherosclerosis care. HDL cholesterol, commonly
known as the "good" cholesterol, can help clear the fatty deposits from the
walls of blood vessels and transport cholesterol to the liver for processing
and removal from the body. Drugs that can influence the levels of HDL
cholesterol may potentially provide clinical benefits to patients by reducing
the risk of heart attack and stroke.
About Arena Pharmaceuticals
Arena is a clinical-stage biopharmaceutical company focusing on the
discovery, development and commercialization of small molecule drugs in four
major therapeutic areas: metabolic, central nervous system, cardiovascular and
inflammatory diseases. Arena is developing a broad pipeline of compounds
targeting an important class of drug targets called G protein-coupled
receptors, or GPCRs, using its knowledge of GPCRs and its technologies,
including CART (Constitutively Activated Receptor Technology) and
Melanophore. Arena has four internally discovered, clinical-stage drug
candidates for major diseases. The most advanced is lorcaserin hydrochloride,
a selective 5-HT2C serotonin receptor agonist that is under investigation for
the treatment of obesity and is expected to enter Phase 3 clinical development
in the second half of 2006. Arena's lead drug candidate for the treatment of
insomnia, APD125, is a compound with a novel mechanism of action (a selective
5-HT2A receptor inverse agonist) with an IND pending before the FDA for the
initiation of a Phase 2 trial in patients with chronic insomnia. Arena also
has two clinical-stage collaborations with major pharmaceutical companies:
Merck & Co., Inc., began a Phase 2 clinical trial of MK-0354, an Arena
discovered drug candidate for the treatment of atherosclerosis and related
disorders, in the second quarter of 2006; and Ortho-McNeil, Inc., a Johnson &
Johnson company, began a Phase 1 clinical trial of APD668, an Arena discovered
drug candidate for the treatment of type 2 diabetes, in the first quarter of
Arena Pharmaceuticals® and Arena® are registered service marks of the
company. CART is an unregistered service mark of the company. "APD" is
an abbreviation for Arena Pharmaceuticals Development.
