Breakthrough Drugs See Shorter Development Times: Analysis

Share
Cancer therapies are reaping rewards under FDA’s breakthrough therapy program. According to a new analysis released by Friends of Cancer Research (FOCR), drugs with breakthrough designations gained approval more quickly than those without the designation and they experienced faster pre-market development and review times. “We also found that considerably more breakthrough-designated drugs were approved via the accelerated approval pathway than non-designated drugs, and that breakthrough-designated drugs were more often approved on the basis of Phase 1 or Phase 2 trials,” FOCR says. “We also conclude that, owing to the large number of accelerated approvals among breakthrough-designated drugs, the FDA is more willing to take measured risks in approving drugs that show early evidence of substantial improvement over available therapy.”

Breakthrough drugs typically were approved about three months before their user fee goal dates compared with those without the designation,” the group says. “Pre-market development time, calculated as the number of years from submission of an investigational new drug application (IND) to submission of a new drug application (NDA) or biologics license application (BLA), was considerably shorter among approved breakthrough-designated drugs (median 5.2 years) than non-designated drugs (median 7.4 years), a difference of 2.2 years,” it says.
