Separate GSK, AstraZeneca trial results may widen ovarian cancer drug use

GlaxoSmithKline and AstraZeneca both reported trial results that will likely make their competing drugs available to a wider group of ovarian cancer patients, possibly helping GSK catch its rival in a highly contested drug class.

The companies said separately on Saturday their respective drug candidates - in a class known as PARP inhibitors - staved off the return of metastasized ovarian cancer in women who had responded to initial standard treatment, reducing the risk of a relapse.
