Antigenics Asks European Regulators to Approve Oncophage for Kidney Cancer
Antigenics, the developer of a personalized treatment to stimulate the immune system to fight tumors, is asking European regulators for permission to sell its vitespen (Oncophage) treatment for kidney cancer. It’s a big step for the New York-based company—which has 90 of its 98 employees in Lexington, MA—on its quest to be the world’s first to bring such a product to a wide market of patients.
The move comes six months after Antigenics (NASDAQ: AGEN) won clearance to market the immune stimulator in Russia, the first market where the drug is approved for sale. The company is now asking European regulators to do the same, even though its main clinical trial supporting the product failed to reach its primary goal. Antigenics made a case in Russia that although the trial of 604 patients failed to lower the risk of relapse after kidney tumors were surgically removed, it did help 60 percent of people stay in remission longer if they had an intermediate risk of recurrence.
That sort of “subset analysis” of patients is generally considered a “fishing expedition” by the FDA, and isn’t good enough to win approval here in the States. Antigenics hopes to get its treatment cleared in Europe through what’s known as “conditional approval,” a European Union regulatory provision introduced in April 2006 that provides patients access to new drugs when no satisfactory treatment option is readily available, Antigenics says. More than 60,000 people were diagnosed with kidney cancer in EU member countries in 2004 and about half that many died, the company says. Antigenics had three meetings with European regulators to sort through the options before it decided to go ahead and ask for approval, says spokesman Sunny Uberoi.
“This application represents a major achievement in the development of Oncophage, and if approved, will be the first therapeutics cancer vaccine to receive a marketing license from the European agency,” said Garo Armen, Antigenics’ CEO, in a statement.
