ITEM 8.01   OTHER EVENTS.

On December 13, 2006, Celgene Corporation, or the Company, announced that it has
been notified of an Abbreviated New Drug Application (ANDA) filed with the U.S.
Food and Drug Administration (FDA), with a Paragraph IV certification, by Barr
Pharmaceuticals, Inc. This applicant is seeking authorization to market a
generic version of thalidomide 200 mg tablets in the United States for the acute
treatment of cutaneous manifestations of moderate to severe erythema nodosum
leprosum (ENL).

The Company intends to file a complaint alleging infringement of Celgene
patents, within the required forty-five day response period. By bringing suit,
Celgene is entitled to up to a 30-month injunction against the applicant's
marketing of generic thalidomide. The Company has seven issued patents which
cover methods of more safely administering thalidomide through S.T.E.P.S.(R),
an integral part of the FDA approved THALOMID(R) labeling and additional broad
patents protecting methods of using thalidomide in the treatment of
hematological and solid tumor cancers.

Attached hereto as Exhibit 99.1 is the Press Release announcing this event.
