On Friday, Schering said that Pegintron, which stimulates the immune system, was able to extend the time it took for melanoma to return after the skin cancer was surgically removed from the lymph nodes.
The big question is whether slowing the return of cancer will be enough to get Pegintron approved as a treatment for melanoma, or whether the FDA will want to see data that proves that the added treatment extends patients' lives. The clinical trial didn't show that Pegintron helped with overall survival, but the study isn't entirely completed.
Schering's best hope for getting Pegintron approved to treat melanoma lies in the fact that melanoma has few treatment options. The cancer has been a wasteland for drugs like Pfizer's
Since Pegintron is an immunotherapy, it could be safe from competition from upcoming melanoma chemotherapy treatments like Array BioPharma's
Investors will have to wait and see what the FDA does, but I don't think they should count on much of a bump from cancer sales for this near-blockbuster drug.
