US regulators have approved Pfizer’s PARP inhibitor Talzenna to treat patients with breast cancer carrying a certain mutation, identified by a companion diagnostic developed by Myriad.
Following weeks of speculation Pfizer has stepped forward with a $14-billion bid for Medivation, beating Sanofi and other suitors to the finish line in a move designed to boost its oncology portfolio.
Sanofi is gearing up to challenge Medivation’s Board of Directors on the grounds that it has thus far rebuffed any attempts to discuss its proposed takeover of the firm.
