The Subcommittee on Health of the US House of Representatives Energy and Commerce Committee held hearings last week to discuss the findings of a report by the Federal Trade Commission (FTC) that examined the competitive effects for follow-on-biologics (FOBs).
The Subcommittee on Health of the US House of Representatives Energy and Commerce Committee held hearings last week to discuss the findings of a report by the Federal Trade Commission (FTC) that examined the competitive effects for follow-on-biologics (FOBs). The report comes as Congress considers various legislative proposals for establishing a regulatory approval pathway for FOBs.
In releasing the report, FTC Chairman Jon Leibowitz set the overarching position of the FTC. “If Congress creates an efficient pathway to follow-on biologic drugs and, at least as important, ends ‘pay-for-delay’ pharmaceutical settlements that delay entry of traditional generic drugs, it will be taking a major step forward for both healthcare reform and affordable drugs for all Americans,” he said in prepared statement.
FTC Commissioner Pamela Jones Harbour, who testified before the House subcommittee on June 11, highlighted key findings from the report:
Patent exclusivity a critical area of debate
Henry A. Waxman (D-CA), chairman of the House Energy and Commerce Committee, supported the report’s finding for reducing the length of time for exclusivity. "The report completely disposes of the drug industry's argument that they need 12 to 14 years of exclusive marketing, indeed that they need any additional exclusivity, to sustain innovation,” said Waxman in a prepared statement.
The Generic Pharmaceutical Association (GPhA) President and CEO Kathleen Jaeger also supported the report’s position regarding exclusivity. “It is important to remember that when Congress debated the Hatch-Waxman Act 25 years ago, the same arguments that we are hearing today about the need for excessive periods of exclusivity, product safety, and generic use by consumers have all been proven wrong,” she said in a prepared statement. “Beyond a shadow of a doubt, Hatch-Waxman has proved that competition from safe and effective generic medicines can truly foster brand innovation while also creating extraordinary savings.” GPhA estimates that there are more than 42 companies engaged in biogeneric development in the United States.
The Biotechnology Industry Organization (BIO), which represents biotechnology companies in the US, refuted the FTC report. Although BIO agreed with the FTC report that biosimilar competition would resemble brand-to-brand competition among biologics in terms of the number of entrants, price competition, and market-share erosion in the short term, it pointed to what it sees as a key difference between innovator and biosimilar manufacturers. “Biosimilar manufacturers will be given a scientific and regulatory shortcut that, while more demanding than small-molecule generic-drug entry, will be considerably shorter and cheaper than the process that the initial innovator would have to go through,” said BIO in its rebuttal.
BIO also asserted that the comparison of exclusivity of biologics with small molecules is faulty. For small molecules, the regulatory approval standard for generics and the patent system provide protection against premature generic competition for an average of 12-14 years. “The regulatory approval standard for biosimilars creates a ‘patent protection gap’ that may allow for abbreviated regulatory approval of a biosimilar [that] does not infringe an innovator’s patent,” said BIO. The association noted that proposed measures for a biosimilar pathway would require a biosimilar to be only “similar” to the corresponding innovator product. The association contends that certain proposed legislative measures (i.e., HR 1427) that although requiring a biosimilar to have the same mechanism of action, dosage form, and strength as the innovator drug, would also provide for discretionary authority to waive part or all of these requirements.
White House weighs in on debate
Although not endorsing a specific legislative proposal, President Barack Obama offered his support for developing a regulatory approval pathway for FOBs. “We need to introduce generic biologic drugs into the marketplace,” he said in a speech before the American Medical Association on June 15. “These are drugs used to treat illnesses like anemia. But right now, there is no pathway at the FDA for approving generic versions of these drugs.”
