Weight loss

First-in-human phase 1, Part C/D

13.1% reported weight loss · 1.2% loss with placebo · 12 weeks

2 × 50 mg tablets once daily (100 mg total), escalated

Adults with overweight or obesity, without diabetes

Prespecified exploratory pharmacodynamic endpoint; full analysis set Investigational; oral formulation included in AMAZE phase 3 programme

Safety context

Reported adverse events were mild/moderate, mostly gastrointestinal; frequency increased with dose.

Limitations: Only 60 participants were in 12-week cohorts; 144 is all parts. Small exploratory trial, not pivotal efficacy.

Weight loss

Phase 1b/2a, Part B dose escalation

24.3% reported weight loss · 1.1% loss with placebo · 36 weeks

Escalation up to 60 mg once weekly

Adults aged 18–55 with BMI 27.0–39.9, without diabetes

Early-phase estimated mean from dose-escalation cohort; not verified as a treatment-policy estimand Investigational; AMAZE phase 3 obesity programme initiated in Q1 2026

Safety context

Frequent GI effects; substantial withdrawals, many unrelated to treatment-emergent adverse events.

Limitations: 125 is whole multipart trial, not top-dose cohort. Small early-phase safety study; no phase 3 obesity outcome yet.

Glucose control

Zenagamtide phase 2 T2D

1.71 percentage-point HbA1c decrease · 0.14 pp decrease with Placebo · 36 weeks

40 mg weekly

Adults with type 2 diabetes

Primary efficacy estimand, using on-treatment data without rescue medication.

Safety context

Most adverse events were gastrointestinal and mild or moderate.

Limitations: Only four weeks at 40 mg maintenance dose; fixed escalation required discontinuation for intolerance. Trial-wide baseline.

Glucose control

Oral zenagamtide phase 2 T2D

1.4 percentage-point HbA1c decrease · comparator result not extracted · 36 weeks

50 mg daily

Adults aged 18–75 with type 2 diabetes; BMI 23 to under 50 kg/m²; HbA1c 7–10%

Primary efficacy estimand, using on-treatment data without rescue medication.

Safety context

GI adverse events in 24/51 (47%) at 50 mg; serious adverse events in 3/51; no deaths.

Limitations: Small dose-finding trial. Absolute placebo reduction and exact arm baseline were not extracted; reported baseline means span 7.9–8.1%.

Selected milestones only. Earlier studies may be missing; the first listed date should not be interpreted as the start of development.

  1. Oral phase 1 findings presented

    Novo Nordisk's Capital Markets Day introduced early oral amycretin data; this was an exploratory early-phase result, not an approval.

    Source
  2. Subcutaneous phase 1b/2a topline announced

    Novo Nordisk disclosed results from the multipart study of weekly injections. The announcement date is not a precise trial-completion date.

    Source
  3. Subcutaneous study published

    The phase 1b/2a paper described dose-escalation and dose-response cohorts, including the up-to-60 mg cohort used in the endpoint map.

    Source
  4. AMAZE phase 3 progress confirmed

    The Q2 2026 presentation reports that the obesity program began in Q1 2026 and describes oral AMAZE 9 separately. This is a dated sponsor status disclosure; individual formulation timelines differ.

  5. Announcement

    AMBIENCE cardiovascular-outcomes trial registered

    Registry first posting, not actual initiation: 8,500 planned adults with established ASCVD and overweight/obesity, with or without stable type 2 diabetes. Phase 3 placebo comparison on four-point cardiovascular events; not yet recruiting. October 26 start and September 16, 2030 completion are estimates; no event benefit established.

  6. Announcement

    New trial studies tolerability when switching from tirzepatide to zenagamtide

    A 60-person phase 1 switching study from maintenance tirzepatide to zenagamtide is registered, not yet recruiting after an estimated October 8 start. Primary endpoint is adverse-event count through day 57; no combination dosing, randomized continuing-tirzepatide comparison or efficacy superiority is established.

    Source
  7. Announcement

    Zenagamtide switching study now records recruitment and an actual start

    The tirzepatide-to-zenagamtide study resolves its elapsed October start estimate, while remaining a small uncontrolled tolerability study. September 7, 2028 estimated primary/final completion; no public-result date. The registry reports actual October 8 study start; October 16 is the posted update date.
