ITEM 5. OTHER INFORMATION.

            Alkermes, Inc. announced that its partner, Johnson & Johnson
Pharmaceutical Research & Development (J&JPRD), has submitted additional data
and analyses to the U.S. Food and Drug Administration (FDA) to fulfill a
complete response to the "non-approvable" letter issued by the FDA regarding the
New Drug Application (NDA) for Risperdal Consta(TM) long-acting injection. The
specific data and analyses provided were generated following discussions with
the FDA, particularly related to the agency's questions pertaining to aspects of
the preclinical data presented in the NDA for the long-acting injection form of
the atypical antipsychotic, risperidone. It is anticipated, based on criteria
set forth in the Prescription Drug User Fee Act (PDUFA), that the FDA will issue
a formal response to the submission in the fourth quarter of calendar year 2003.
A copy of the press release issued by Alkermes on April 29, 2003, is attached
hereto as Exhibit 99.1 and is incorporated herein by reference.
