Harvard Reseachers Ask: Why No Generics?

Harvard Medical School researchers say policymakers should examine 25 high-cost drugs they studied to determine why generic or biosimilar versions are not yet on the market and how to take steps to facilitate entry for the benefit of patients and to reduce unnecessary Medicare spending. Writing online in the Journal of General Internal Medicine, the researchers say they looked at the novelty of active ingredients in the 25 branded drugs with the highest Medicare Part D spending in 2017.

Among the 27 active ingredients identified, 11 (41%) had previously been approved by FDA in other formulations or products. “Many active ingredients in the 25 brand-name drugs with the highest Medicare spending were discovered decades ago, with a substantial minority having been previously marketed in alternative formulations or products,” the researchers say. “Repurposing already approved drugs in new formulations, drug/device combinations, or for new indications is a less costly form of drug innovation, because preclinical work and early-phase clinical trials may be streamlined, and is also less risky for sponsors. High Medicare spending on such older products is facilitated by patents on new delivery devices or formulations, which can protect against entry of low-cost generic versions.”
