Shares of Medarex slipped seven percent this morning as investors digested Friday's announcement that its application for a new cancer drug will be delayed into 2009. The developer says that the FDA wants more data on ipilimumab, which is in late-stage trials. Bristol-Myers Squibb is partnered on the therapy, which is being investigated as a new treatment for metastatic melanoma. The agency is looking for more data on overall survival rates. That left the analysts scrambling to calculate the revenue the company will lose as a result of the delay. Medarex shares have lost more than half of their value since last summer.
