ZURICH (Reuters) - Roche said on Wednesday its drug Kadcyla, a treatment for an aggressive form of breast cancer, had been approved in Europe following U.S. approval in February.
Kadcyla treats patients with late-stage disease whose cancer cells contain increased amounts of a protein known as HER2.
It works by attaching Herceptin to a drug called DM1, developed by ImmunoGen, which interferes with cancer cell growth. ImmunoGen will receive a $5 million milestone payment from Roche following the approval.
