About Perifosine
Perifosine is a novel, oral anticancer treatment that inhibits Akt activation in the phosphoinositide 3-kinase (PI3K) pathway. The product works by interfering with membranes of cancer cells thereby inhibiting Akt signaling which then affects cell death, growth, differentiation and survival. Perifosine, in combination with chemotherapeutic agents, is currently being studied for the treatment of multiple myeloma, colorectal cancer and other cancers, and is the most advanced anticancer agent of its class. Perifosine, as monotherapy, is being explored in other indications. The US Food & Drug Administration (“FDA”) has granted perifosine orphan-drug designation in multiple myeloma and neuroblastoma, and Fast Track designations in both multiple myeloma and refractory advanced colorectal cancer. Additionally, an agreement was reached with the FDA to conduct the Phase 3 trials in both of these indications under a Special Protocol Assessment. Perifosine has also been granted orphan medicinal product designation from the European Medicines Agency (“EMA”) in multiple myeloma. Furthermore, perifosine has received positive Scientific Advice from the EMA for both the multiple myeloma and advanced colorectal cancer programs, with ongoing Phase 3 trials for these indications expected to be sufficient for registration in Europe. Perifosine rights have been licensed to Keryx Biopharmaceuticals for North America, Yakult Honsha for Japan and to Handok for Korea.
