This article is for subscribers only.
Puma Biotechnology Inc. almost tripled in extended trading after the company said a clinical trial of its experimental drug blocked the return of breast cancer in women with a type of early-stage disease.
The drug, neratinib, improved disease-free survival by 33 percent compared with a placebo in a trial of 2,821 women with early-stage HER2-positive breast cancer, Los Angeles-based Puma said today in a statement. Disease-free survival refers to the interval a patient remains alive and free of signs of the illness. The company said it would apply for U.S. regulatory approval in the first half of 2015 based on the results.
