The Big 3

1
CMS unveils new Medicare coverage model for weight loss drugs
  • The Centers for Medicare & Medicaid Services (CMS) has introduced a new payment model that expands Medicare coverage for GLP-1s, potentially increasing access to popular weight loss medications.
  • Why it matters: If this model sticks, it’s a real wedge for Medicare reimbursement of obesity GLP-1s — expanding the reimbursed patient pool, shifting leverage in price/rebate negotiations, and forcing manufacturers to prove value under tighter utilization controls.

Biohaven's ion channel drug fails in major depressive disorder trial
  • Biohaven's experimental ion channel drug did not meet its endpoints in a Phase 2 clinical trial for major depressive disorder, marking a setback for the company.
  • Why it matters: Another Phase 2 miss raises the bar for Biohaven’s near-term catalyst stack — and increases pressure to re-prioritize the pipeline (and spending) toward programs with cleaner efficacy signals.

J&J removes eczema drug from $1.25B acquisition deal
  • Johnson & Johnson has decided to exclude an eczema drug from its $1.25 billion acquisition, reportedly due to concerns over the drug's efficacy.
  • Why it matters: This is big pharma underwriting discipline in real time: when the clinical signal looks shaky, valuation gets reset fast — and it’s a reminder that “platform” excitement doesn’t survive weak dermatology efficacy.
