HATFIELD, England, November 8, 2013 /PRNewswire/ --

Eisai announces today that it has expanded the marketing and supply agreement
between its U.S. subsidiary Eisai Inc. and U.S-based Arena Pharmaceuticals
Inc.'s Swiss subsidiary, Arena Pharmaceuticals GmbH, for the anti-obesity
agent lorcaserin hydrochloride (lorcaserin) (U.S. brand name: BELVIQ ^® ).
Whilst the existing agreement granted Eisai Inc. exclusive rights to market
and distribute lorcaserin in 21 countries throughout the Americas, the
expanded agreement now includes most countries and territories worldwide, most
notably, the member states of the European Union, Japan and China (but
excludes South Korea, Taiwan, Australia, New Zealand and Israel).

Under this agreement, Eisai will be working in collaboration with Arena to
develop and seek marketing authorisation of lorcaserin as an anti-obesity
treatment in its territories. In addition to pursuing regulatory approval for
weight management in the expanded territories, Eisai and Arena plan to
investigate the potential of lorcaserin in new areas, such as: smoking
cessation, a once-daily formulation, a fixed-dose combination with
phentermine, as well as explore lorcaserin's impact on diabetes and
cardiovascular outcomes.

Lorcaserin is marketed in the U.S. by Eisai Inc., and is approved by the U.S.
Food and Drug Administration (FDA) as an adjunct to a reduced-calorie diet and
increased physical activity for chronic weight management in adult patients
with an initial body mass index (BMI) of 30 kg/m ^2 or greater, or 27 kg/m ^2
or greater in the presence of at least one weight-related co-morbid condition.
Marketing authorization has also been applied for in Mexico and Canada.

In recent years, obesity has become a major global health problem, with more
than 1.4 billion adults worldwide believed to be overweight and approximately
500 million of that number qualifying as obese. ^[1] By region, around 170
million people in the United States ^[2] and 150 million people in Europe are
reported to be obese or overweight. ^[3] In Europe, it is estimated that
10-30% of adults are obese. ^[4]

therapies that can make a difference and impact the lives of patients and
their families. This passion for people is part of Eisai's human health care
(hhc) mission, which strives for better understanding of the needs of patients
