FDA Panel Backs 6 Peptides for Compounding

The FDA's Pharmacy Compounding Advisory Committee (PCAC) closed its July 23-24 meeting with a string of narrow votes recommending 6 of the 7 peptides under review—BPC-157, KPV, TB-500, MOTS-c, Semax, and Epitalon—for the agency's 503A Bulks List, overriding career scientists who had recommended against including any of the 7.^1,2 The panel's single rejection was emideltide (delta sleep-inducing peptide), voted down 7-6 with 1 abstention.¹

On July 23, the committee voted 8-6, with 1 abstention, to recommend BPC-157, KPV, and TB-500; MOTS-c passed 7-5 with 2 abstentions.³ Semax and Epitalon were cleared on July 24 by similarly tight margins before emideltide became the meeting's only rejection.¹ Observers in the room described an audible gasp when the first tally was announced, noting that a PCAC panel had rarely, if ever, voted against FDA staff's written recommendation. This follows FDA's decision to convene the reconstituted panel, whose July meeting materials disclosed that FDA scientists uniformly opposed adding any of the 7 substances.⁴

Panel's Recommendation Does Not Equal Legal Access

None of the peptides have been added to the 503A Bulks List, and none is an FDA-approved drug.¹ The FDA must still decide whether to accept the committee's nonbinding recommendations and, if so, proceed through notice-and-comment rulemaking—a proposed rule, a public comment period, and a final rule—before compounding pharmacies could legally prepare the substances for patients. ⁴

Scott Brunner, CEO of the Alliance for Pharmacy Compounding, noted that FDA still must formally adopt the advisers' recommendations before the peptides may be legally compounded.¹ HHS Secretary Robert F. Kennedy Jr, who has called himself “a big fan” of peptides, could seek to expedite that process, though experts say it remains unclear what happens next or on what timeline.

Evidence Gaps and Panel Makeup Drew Scrutiny

FDA scientists' briefing materials found that available studies, including 5 trials of BPC-157, were short in duration, small in sample size, and insufficient to establish safety or effectiveness for the indications under review, which spanned ulcerative colitis, wound healing, obesity, osteoporosis, and opioid withdrawal.⁵

The reconstituted PCAC roster released ahead of the meeting drew scrutiny for including more health professionals who prescribe, produce, or promote peptides than prior iterations of the panel, a shift from committees historically composed mainly of academics and researchers. BPC-157 and TB-500 are both classified as doping substances by international sports authorities and remain widely sold online under "research use only" disclaimers despite the FDA's 2023 restrictions.

Managed Care Implications

For payers and health systems, the panel's votes mark an early procedural step rather than an imminent expansion of covered treatment options.¹ Compounded drugs generally fall outside standard pharmacy benefit coverage, so patients would likely continue paying out of pocket even after any final rule takes effect.⁶

In the interim, managed care organizations should anticipate continued patient use of peptides sourced from unregulated online sellers and should prioritize medication reconciliation, safety counseling, and monitoring for adverse effects, particularly given the limited human safety data the FDA’s own reviewers cited during the review.¹
