FDA PCAC 2026: committee backs six peptides for compounding, rejects Emideltide
On July 23–24, 2026, the FDA's Pharmacy Compounding Advisory Committee recommended adding six of seven reviewed peptides (BPC-157, KPV, TB-500, MOTS-c, Epitalon, Semax) to the Section 503A Bulks List and rejected Emideltide/DSIP. The vote is advisory only — not a final FDA decision and not legal authorization to compound. FDA must still complete formal notice-and-comment rulemaking (typically 12–24 months) before any change in legal status.

Semaglutide’s heart benefits may partly involve reduced inflammation
New research suggests that semaglutide reduces the risk of major adverse cardiovascular events (MACE) not only through weight loss but also by lowering systemic inflammation. A study of over 17,000 patients found that reductions in the inflammatory biomarker hs-CRP accounted for roughly 28% of the drug's cardiovascular benefit. This indicates that semaglutide's mechanism for heart protection involves direct anti-inflammatory effects independent of glycemic control or body weight reduction.
Bristol Myers Squibb Protein Degrader Wins First-in-Class FDA Nod in Multiple Myeloma - MedCity News
The FDA has granted accelerated approval to Bristol Myers Squibb's iberdomide, marketed as Zenbexus, for relapsed or refractory multiple myeloma in combination with dexamethasone and daratumumab. As a first-in-class CELMoD agent, iberdomide is a cereblon-modulating peptide-like molecule that induces targeted protein degradation to eliminate cancer-driving proteins. The approval was supported by Phase 3 data showing a statistically significant improvement in minimal residual disease-negative complete response rates compared to standard care.
Small Businesses Could Face Double-Digit Premium Hikes in 2027 - MedCity News
An analysis of rate filings from small group insurers indicates that small businesses may face a median premium increase of 14% in 2027. The filings identify rising healthcare costs and increased utilization as primary factors, specifically highlighting the financial impact of specialty drugs. Insurers explicitly cite GLP-1 medications as a significant driver behind these escalating costs and subsequent premium hikes.
