As you might guess from the name, CP-870,893 is still in early stages of development; it doesn't even have a generic name, let alone a branded one. The trial didn't have a placebo control, so the 5.6 months of progression-free survival can only be compared with the historic figure of 2.3 months. About a quarter of the patients saw their tumors shrink by at least 30%; typically Gemzar alone would only cause about 5% of patients to achieve that.
