Perifosine (also KRX-0401) is a drug candidate being developed for a variety of cancer indications. It is an alkyl-phospholipid[1] structurally related to miltefosine. It acts as an Akt inhibitor and a PI3K inhibitor. It was being developed by Keryx Biopharmaceuticals who have licensed it from Æterna Zentaris Inc.[2]

In 2010 perifosine has reached phase II.[3] In one phase II trial for metastatic colon cancer perifosine doubled time to progression.[2]

It has orphan drug status in the U.S. for the treatment of multiple myeloma and neuroblastoma, and for multiple myeloma in the EU.[4]

In 2011 it was in a phase III trial for colorectal cancer,[5] and another for multiple myeloma.[4][6] On April 2, 2012, it was announced that perifosine failed its phase III clinical trial for treatment of colon cancer.[7] Detailed results were released in June 2012.[8] On March 11, 2013 Aeterna Zentaris announced the discontinuing of Phase 3 clinical trial of perifosine for the treatment of relapsed and refractory multiple myeloma http://www.aezsinc.com/en/page.php?p=60&q=550.
