Wayne Winegarden, PhD, Evaluates Possible Impact of Adalimumab, Etanercept Biosimilars

Between congressional hearings and executive orders, experts had plenty to draw on when dissecting the barriers to biosimilar access at Festival of Biologics USA to close out April 2025.

Despite saving billions, biosimilars still account for only a small share of the biologics market—what's standing in the way of broader adoption and how can artificial intelligence (AI) help change that?

Sandoz's antitrust suit against Amgen, the FDA’s interchangeability designation for Celltrion’s adalimumab biosimilar, and the inclusion of an ustekinumab biosimilar in Costco’s prescription program highlight growing momentum to expand biosimilar access and affordability for patients with chronic inflammatory diseases.

On this episode of Not So Different, we explore the Federal Trade Commission’s (FTC) second interim report on pharmacy benefit managers (PBMs) with Joe Wisniewski from Turquoise Health, discussing key issues like preferential reimbursement, drug pricing transparency, biosimilars, shifting regulations, and how a second Trump administration could reshape PBM practices.

To help bring down sky-high drug prices, President Donald Trump signed an executive order pushing for faster biosimilar development, more transparency, and tougher rules on pharmacy benefit managers—aiming to save billions and make meds more affordable for everyone.

States with fewer restrictions on biosimilar substitution tend to see higher uptake of interchangeable insulin glargine, showing how even small policy details can significantly influence biosimilar adoption and expand access to more affordable insulin.
