Pfizer Inc., the world’s largest drugmaker, is weighing whether to ask U.S. regulators to expedite their review of a potential $5 billion-a-year treatment to slow a type of incurable breast cancer.

That trial was done in the second of three stages of research regularly required for Food and Drug administration approval.
