Collins Presses for Faster Generic Competition at Hearing

U.S. Sen. Susan Collins (R-ME) used a Senate hearing 4/16 to spotlight barriers to lower-cost drugs, pressing an expert witness on delays in bringing generics and biosimilars to market and promoting her own legislative proposals aimed at reducing prices.

During a Senate Health, Education, Labor, and Pensions Committee hearing, Collins questioned Brian Miller, an associate professor at Johns Hopkins University, about regulatory and competitive hurdles that can slow the availability of cheaper alternatives to brand-name medicines.

Collins pointed to bipartisan bills she has introduced, including the INSULIN Act and the Ensuring Timely Access to Generics Act, which she said are designed to streamline approvals and curb practices that delay competition.

The insulin-focused legislation would cap monthly costs at $35 for insured patients and establish a pilot program for uninsured individuals, while also creating an expedited regulatory pathway for biosimilar insulin products.

Miller told lawmakers that biosimilars can take roughly nine years and cost about $300 million to develop, compared with significantly lower costs and shorter timelines for traditional generic drugs. He argued that simplifying evidentiary requirements, such as focusing on pharmacokinetic data, could reduce development costs and boost competition.

“Old drugs should be cheap,” Miller said, emphasizing that longstanding therapies like insulin should not pose financial barriers to patients.

Collins also raised concerns about misuse of FDA’s citizen petition process, which allows stakeholders to request regulatory review but has been criticized as a tactic used by some manufacturers to delay approvals of competing products.

Miller agreed the process can be exploited, citing cases where companies filed numerous petitions to stall market entry of generics or biosimilars. He suggested FDA should have greater authority to dismiss such petitions and coordinate with antitrust regulators, including the Federal Trade Commission and the U.S. Department of Justice, to address anti-competitive behavior.

The hearing reflects ongoing bipartisan interest in tackling prescription drug affordability, particularly by increasing competition in markets for older therapies where high prices persist despite long-standing availability.
