Johnson & Johnson Pharmaceutical Research & Development, L.L.C. Receives Not Approvable Letter From FDA for Tipifarnib Based on Phase II Data

RARITAN, N.J., June 30, 2005, 2005 -- Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) announced it has received a not approvable letter from the U.S. Food and Drug Administration (FDA) for the tipifarnib new drug application (NDA), which was based on data from a single Phase II study. Tipifarnib is an oral medication studied to treat acute myeloid leukemia (AML) in elderly patients who are not candidates for standard chemotherapy. The not approvable letter explains why the NDA cannot be approved based on currently submitted data.

The company remains committed to the development of tipifarnib. Recognizing the unmet medical need in this area, the company is reviewing the FDA's letter and will determine appropriate next steps.

J&JPRD completed the submission of the tipifarnib NDA to the FDA under the Continuous Marketing Application Pilot-1 Program in December 2004, and the application was discussed at a May 5, 2005 Oncology Drugs Advisory Committee meeting. As a drug intended to treat a life-threatening disease for which there is an unmet medical need, tipifarnib was granted "Fast Track" status by the FDA in June 2004. Tipifarnib also was granted Orphan Drug status, a designation given to medications used to treat a rare disease or condition.

AML is a rare but often fatal cancer that will impact nearly 12,000 Americans in 2005.
