Amycretin: Novo's Amylin + GLP-1 Fusion — 13% in 12 Weeks (2026)

Quick answer:

Amycretin is Novo's single-molecule GLP-1 + amylin agonist — ~13% weight loss in 12 weeks in early trials, injectable AND oral versions. Availability ~2028+. Meanwhile, tirzepatide delivers ~20% now — check eligibility free.

What makes amycretin different

Every current GLP-1 hits one satiety pathway — or two, if it's tirzepatide (GIP+GLP-1). Amycretin hits GLP-1 + amylin, like CagriSema — except it's engineered as a single molecule, not a co-administered combo. That simplification matters: one manufacturing process, one injection, and critically — an oral pill version in parallel development.

  • Injectable: ~13.1% weight loss in 12 weeks (early readout) — unprecedented speed
  • Oral: ~13.1% at 12 weeks in a small Phase 1 cohort — a pill matching early injectable curves would be category-changing

Context: how fast is 13% in 12 weeks?

Drug~12-week resultFull-trial result
Amycretin (injectable)~13%TBD — Phase 3 pending
Wegovy (semaglutide)~5-6%~15-17% at 68 wks
Zepbound (tirzepatide)~8%~20-21% at 72 wks
CagriSema~9-10%~23% at 68 wks

Caveat: early-phase data, small cohorts, no full-duration results yet. The curve will flatten — the question is where it lands relative to ~23%.

Amycretin vs CagriSema: Novo's internal race

  • CagriSema = two molecules (semaglutide + cagrilintide), injectable only, nearer approval (2026-27)
  • Amycretin = one fusion molecule, injectable AND oral, deeper pipeline (~2028)
  • If amycretin's oral version pans out, it could eventually cannibalize CagriSema — Novo is running both
