Investigational — not yet approved

This treatment is in clinical trials and has not been approved by the FDA or any regulatory authority. It is not available for prescription. Current stage: Phase 2 complete; Phase 3 starting Q1 2026 (obesity + T2D). Estimated approval: 2028+ (estimated — not confirmed) — subject to change.

Amycretin

Novo Nordisk

A single unimolecular drug that activates both GLP-1 and amylin receptors — hitting the same two targets as CagriSema but in a single molecule rather than two separate drugs combined. Both a weekly injection and a daily pill are being developed. Early data shows exceptional promise, with oral Phase 1 results exceeding oral semaglutide.

Quick read · 4 min

In simple terms:
  • Amycretin is an investigational drug — it has not yet been approved by any regulatory authority
  • Best trial result so far: up to 22% average weight loss
  • Current stage: Phase 2 complete; Phase 3 starting Q1 2026 (obesity + T2D)
  • Expected approval: 2028+ (estimated — not confirmed) — this is an estimate and not confirmed

Why this matters:

Early oral data shows promise, but this is still Phase 1 and 2 data only. Larger Phase 3 trials will be the real test. These treatments are still under investigation, and results in larger trials may differ from early data.

Development stage and timeline

Current stage:

Phase 2 complete (injection + oral + T2D). Phase 3 trials for obesity starting Q1 2026. Phase 3 for T2D also planned.

Next milestone:

Phase 3 obesity trials enrolling 2026. Phase 3 T2D trials planned. Estimated approval: 2028+ (very preliminary; not confirmed).

How it works

A single molecule designed to agonise both GLP-1 receptors (appetite reduction, gastric slowing) and amylin receptors (appetite reduction, gastric slowing via brainstem pathways). The single-molecule approach may simplify manufacturing compared to a fixed-dose combination like CagriSema.

Timeline note: Phase 1 oral data showed significant weight loss within 12 weeks; subcutaneous Phase 2 data over 36 weeks

Early-stage data

Phase 1 and Phase 2 data only. Phase 3 trials are planned but not yet complete. Early results should be interpreted with caution.

Subcutaneous injection20 mg once-weekly · 36 weeks

In trial data, 22% mean weight loss vs. 2% weight gain in placebo (Phase 1b/2a)

Oral tablet2 × 50 mg daily · 12 weeks

In trial data, 13.1% weight loss vs. 1.1% placebo (Phase 1). Compared to oral semaglutide (~6% at same timepoint).

Subcutaneous injection (T2D)Once-weekly (various doses) · 36 weeks

In trial data, 14.5% weight loss in Phase 2 T2D trial. 89.1% of patients reached HbA1c below 7%. Mean HbA1c reduction of 1.8%.

Side effects (early-stage data)

Frequencies from Phase 2 trial data. Final Phase 3 safety profile may differ.

Vomiting(20%)
Diarrhoea(18%)

Notable findings

  • Oral formulation showed 13.1% weight loss in 12 weeks — outperforming oral semaglutide at the same timepoint (6%)
  • Single molecule may be simpler to manufacture than CagriSema's two-drug combination
  • Both injection and pill formulations in development — offering choice

What this tends to offer vs. what it involves

What this tends to offer

  • Promising early data: 22% (injection) and 13.1% (pill) in small trials
  • Single-molecule design simpler than two-drug combinations
  • Both injection and oral pill in parallel development
  • Oral formulation showing early signs of outperforming oral semaglutide

What this involves

  • Very early stage — Phase 1 and 2 data only
  • Phase 3 not starting until Q1 2026
  • Approval likely 2028+ — years away
  • No cardiovascular or long-term safety data yet

Community insights

These are personal experiences shared in public online communities — not medical advice.

This is genuinely early — Phase 1 and small Phase 2 data only. The 22% and 13.1% numbers are exciting but from tiny, short studies.

r/antiobesitymedication·Cautious perspective shared when early data was discussed

The oral formulation with no food timing restrictions is frequently discussed as a key differentiator from oral semaglutide.
