VIDEO: Interchangeability of biosimilars and parent compounds raise potential efficacy issues

WAILEA, Hawaii – Biosimilars are coming to dermatology, but their impact from a clinical and insurance standpoint has yet to be determined, according to Kenneth B. Gordon, MD, professor and chair of the department of dermatology at the Medical College of Wisconsin, Milwaukee.

Biosimilars seem to have reasonably good efficacy, and safety to date has been “pretty consistent” with safety associated with the parent compounds, but a key issue will be how they are used in patients on anti-TNF agents who have been doing well over time, Dr. Gordon said in a video interview. Because these medicines cross react in terms of immunogenicity and are not quite the same, “trying to use them interchangeably, as many insurance companies will ask us to do, is going to be difficult,” he noted.

His concern does not apply to a new patient starting on a biosimilar. “The problem I see is when insurance companies and pharmacies start mandating us going back and forth between medicines, and running into difficulty with loss of effect of those drugs,” he explained. “It’s not a safety issue, it’s more of an issue of losing efficacy of a formerly active drug,” he said at the meeting provided by Global Academy for Medical Education/Skin Disease Education Foundation.

Dr. Gordon disclosed financial relationships with AbbVie, Amgen, Boehringer Ingelheim, Janssen, Lilly, Celgene, Novartis, and Sun.
