FDA Approves Tykerb for Her-2 Positive Advanced Stage Breast Cancer Patients

Last week, the FDA approved Tykerb, a targeted therapy for the treatment of women with advanced Her-2 positive breast cancer.   While similar Herceptin, Genentech's Her-2 blockbuster, Tykerb differs from Herceptin in a meaningful way.    "Unlike, for example, trastuzumab [Herceptin]--a monoclonal antibody, which is a large protein molecule that targets the part of the HER2 protein on the outside of the cell--Tykerb is a small molecule that enters the cell and blocks the function of this and other proteins."  Tykerb will be distributed by GlaxoSmithKline.

Commenting on the new drug, Steven Galson, Director of FDA's Center for Drug Evaluation and Research, stated, "New targeted therapies such as Tykerb are helping expand options for patients."
