Now, the company is betting on cancer drugs to help it regain its footing after a rocky year marked by the rapid decline of its Covid business. That $43 billion Seagen acquisition doubled Pfizer's oncology drug pipeline to 60 different experimental programs. Some analysts noted that it might take a few years for some of Pfizer's cancer drugs in mid-stage development to show pivotal clinical trial data and become less risky. Revenue from the blockbuster breast cancer drug Ibrance and prostate cancer treatment Xtandi, which Pfizer shares with Astellas Pharma, has declined over the past year. They are among the most expensive prescription drugs in the U.S. Before the Seagen deal, 94% of Pfizer's cancer products were small-molecule drugs.
