The end for Cell Genesys came Thursday after an independent futility analysis found the company's GVAX prostate cancer vaccine had little chance of success. Cell Genesys was forced to halt the
GVAX prostate phase III study
, the second such late-stage
GVAX prostate cancer study
shuttered in recent months.
Cell Genesys has stopped all clinical development of its GVAX cancer vaccine program and is laying off a majority of its employees. With little else on its plate, the company's future is bleak. The stock is now valued at pennies per share and shareholders have lost everything.
is now the last company standing with a prostate cancer vaccine in clinical trials.
