Treatment for Acute Myeloid Leukemia

Johnson & Johnson Completes Submission of Tipifarnib NDA to FDA

RARITAN, N.J., January 24, 2005 -- Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) has completed the submission of a New Drug Application (NDA) for tipifarnib, an investigational cancer drug, to the U.S. Food and Drug Administration (FDA) Continuous Marketing Application (CMA) Pilot-1 Program. Tipifarnib, administered orally, is being investigated in patients 65 years of age and older with newly diagnosed acute myeloid leukemia (AML).

As a drug intended to treat a life-threatening disease for which there is an unmet medical need, tipifarnib (R115777) was granted "Fast Track" status by the FDA in June 2004. The Company has submitted the tipifarnib NDA based on Phase II clinical data, which use measurements of activity or responsiveness of a disease to the treatment rather than survival endpoints. In October 2004, J&JPRD initiated a Phase III study to fully demonstrate the clinical benefit of tipifarnib in this condition.

Under the CMA Pilot-1 Program, J&JPRD submitted reviewable units of the tipifarnib NDA as they were completed, receiving ongoing feedback from the FDA. The standard FDA review time for the CMA Pilot-1 Program is six months following submission of the final reviewable unit. Tipifarnib also was granted Orphan Drug status, a designation given to medications used to treat a rare disease or condition.

"The Fast Track status of tipifarnib reflects a significant unmet medical need, and this is particularly rewarding for our company because tipifarnib was discovered within the Johnson & Johnson research organization," said Garry Neil, M.D., president, Johnson & Johnson Pharmaceutical Research & Development.

In addition to funding global clinical studies for tipifarnib, J&JPRD collaborated with the National Cancer Institute's (NCI) Cancer Therapy Evaluation Program (CTEP), which sponsors clinical studies in many diseases, including those with unmet medical needs to accelerate access to new compounds. CTEP, under a Clinical Trials Agreement between J&JPRD and NCI, conducted the pivotal Phase II study that supports the tipifarnib NDA. In October 2004, J&JPRD initiated the Phase III international study. J&JPRD continues to investigate other potential uses of tipifarnib in solid and hematologic malignancies, including various stages of myeloid leukemia.

If approved, tipifarnib will be marketed in the United States by Tibotec Therapeutics, a division of Ortho Biotech Products, L.P. J&JPRD will seek approval from regulatory authorities around the world for tipifarnib.
