How Science and Strategic Collaboration Led to a New, “Personalized” Cystic Fibrosis Treatment for Some Patients

written by Janet Woodcock, MD, Director for FDA’s Center for Drug Evaluation and Research

Targeting a drug for small subgroups of patients is a new way to find effective therapies. This is often called personalized medicine, and it’s one of today’s most promising areas of new drug development. Last year, FDA approved two important targeted medicines: Xalkori (crizotinib), a lung cancer drug that targets tumors with the abnormal ALK gene, and Zelboraf (vemurafenib), a drug to treat malignant melanomas that have a certain gene mutation. Both drugs were approved with companion diagnostic tests to identify if patients have a susceptible tumor.

Today, the FDA approved Kalydeco (ivacaftor) to treat a specific subgroup of patients with cystic fibrosis (CF). Cystic fibrosis is an inherited genetic disease that affects a person’s lungs and other organs and may lead to an early death. What makes the availability of Kalydeco even more unique is that the drug’s developer, Vertex Pharmaceuticals, teamed up with the Cystic Fibrosis Foundation to develop and study the drug.
