At present, two biosimilars with an oncology supportive care indication are currently approved in the U.S. and both are myeloid growth factors. In the next few years, manufacturer patents for multiple cancer biologics will expire, paving the way for more oncology biosimilars to be approved.
The potential impact of generic competition for oncology biologics could be dramatic; however, a myriad of factors are creating barriers to adoption and uptake in the U.S., including patient and physician education on the financial impact, safety and equivalency of biosimilars. Still, in a value-based care environment, the potential cost savings make biosimilars a very attractive option. It will be critical for oncologists to understand how these drugs are regulated, approved and paid for going forward.
This article from JAMA Oncology analyzes the hurdles facing biosimilar use in oncology in the U.S. and proposes solutions to perceived barriers in adoption.
