Pipeline Updates / August 2004

Phase II
Pure Anti-Estrogen

In light of changing research and development priorities, a decision was made to seek outside partners for the future development of a pure anti-estrogen. Post-menopausal studies in Phase II had been on hold pending the outcome of FDA guidance on hormone replacement therapy products. This agent will no longer appear on the company’s Product Pipeline.

CCR5 Receptor Antagonist for HIV infection has advanced to Phase II on the Product Pipeline.

Phase III
ASMANEX (MDI)

Development of the ASMANEX MDI formulation in Phase III has been discontinued. This formulation will no longer appear on the company’s Product Pipeline.

Garenoxacin

In June, Schering-Plough signed a definitive license agreement with Toyama Chemical Co. Ltd. for garenoxacin, Toyama’s proprietary quinolone antibacterial agent in late-stage development. As previously disclosed, the company is proceeding with its review of the product dossier and implementation of technology transfer steps, and expects to be in a position to file a U.S. NDA by late 2005.

The following compounds or indications have advanced to Phase III on the Product Pipeline: INTEGRILIN for early acute coronary syndrome, Posaconazole for prophylactic treatment of serious fungal infections and TEMODAR for first-line glioblastoma multiforme.

NDA/HRD Filed

U.S. regulatory submissions have been accepted as filed for the following compounds: CLARINEX-D 24 Hour for seasonal allergic rhinitis, NASONEX for polyposis and Posaconazole for serious fungal infections.

International regulatory submissions have been accepted as filed for the following compounds: REMICADE for psoriatic arthritis, ASMANEX DPI for COPD and Posaconazole for serious fungal infections.

Note:

As part of the current Phase II program for the Adenosine 2a Receptor Antagonist in Parkinson’s disease, the company is reviewing several back up compounds to determine whether they offer a better profile than the original compound.

CLARINEX-D 12 Hour is listed in Phase III on the Product Pipeline. As previously reported, based on an analysis of an October 2001 “approvable” letter, SGP has determined that it intends to reformulate the product and seek approval for a new version with improved stability.
