Fablyn Approved in Europe for the Treatment of Osteoporosis

Ligand Pharmaceuticals Incorporated today announced that its partner, Pfizer, Inc. has received approval from the European Commission(EC) for FABLYN® (lasofoxifene) Tablets, a selective estrogen receptor modulator (SERM) for the treatment of osteoporosis in post-menopausal women at increased risk of fracture. FABLYN was submitted for approval in Europe in January 2008. This is the first regulatory approval for FABLYN, a product that stems from a 1991 research collaboration with Ligand.

As a result of the first approval of FABLYN in a major market, Ligand has earned a $3 million milestone payment. Pursuant to the 1991 research agreement and 1996 settlement agreement with Pfizer, Pfizer has elected to pay the milestone payment by returning 323,338 shares of stock it owns in Ligand. The shares are valued as of the date of the settlement agreement adjusted for Ligand's 2007 return of capital paid to Ligand shareholders. After the payment of this milestone, Pfizer owns a remaining 674,230 shares in Ligand.

Pfizer is responsible for the registration and worldwide marketing of FABLYN. Ligand is entitled to receive royalty payments on net sales of the product. In January 2009, Pfizer received a complete response letter from the FDA requesting additional information for FABLYN. On September 8, 2008, the FDA's Advisory Committee for Reproductive Health Drugs voted 9-3 (with one abstention) that there is a population of postmenopausal women with osteoporosis in which the benefits of lasofoxifene likely outweigh the risks. FDA is not required to follow the advice of the panel.

“Today's announcement is an exciting development for Ligand as the European approval of FABLYN marks the fourth drug associated with Ligand's research platform that has been approved and the second to be approved in just the past six months. This milestone payment reduces Ligand's outstanding shares and paves the way for potential future royalty payments and cash flow following the launch of the product,” said John L. Higgins, President and Chief Executive Officer of Ligand Pharmaceuticals. “We applaud Pfizer for its commitment and diligence in advancing the product to approval and developing an alternative treatment option for patients in Europe with osteoporosis.”

Osteoporosis Prevalence

The International Osteoporosis Foundation (IOF) reports that more than 75 million people suffer from osteoporosis in Europe, Japan and the U.S. About 30% of all post-menopausal women have osteoporosis in Europe and in the U.S., and at least 40% of them will suffer osteoporotic fractures in their lifetime. In Europe alone, 3.78 million osteoporosis-related fractures were reported in 2000, with an estimated cost of 32 billion euros. In the U.S., the National Osteoporosis Foundation projects an estimated 10 million American women to have osteoporosis in 2010 and almost 26 million to have osteopenia (low-bone mass), placing them at increased risk of osteoporosis.
