Amgen, Allergan biosimilar found as effective as Roche cancer drug

[Reuters] – Amgen Inc and Allergan Plc said their copycat version of Roche Holding AG’s blockbuster cancer treatment, Herceptin, was found as effective as the original in a late-stage study. There were no “clinically meaningful” differences in data gathered from patients given Herceptin and the copycat version, ABP 980, to treat a type of early breast cancer, said Sean Harper, Amgen’s executive vice president of research and development.
