The rival gets the same clock

Human phase 3 · REDEFINE 4; sponsor results February 23, 2026

What happened when the comparator was tirzepatide?

Fictional scene

Subject One brings two stopwatches and proposes starting them on different days. Doctide puts both on the same desk. The visitor begins a victory speech, sees the result sheet, and crosses out the first sentence. The sheet stays.

What changes here

CagriSema did not meet the prespecified primary goal of demonstrating non-inferior weight loss to tirzepatide. [1]

REDEFINE 4 · NCT06131437 · Sponsor topline

Novo reported an open-label phase 3 study of 809 people with obesity and comorbidities. Weekly subcutaneous CagriSema 2.4/2.4 mg was compared directly with tirzepatide 15 mg. Efficacy-estimand weight loss, assuming adherence, was 23.0% versus 25.5%; treatment-regimen estimates were 20.2% versus 23.6%. The primary non-inferiority endpoint was not met. [1]

What this does not establish

Open-label assignment was known to participants and investigators. These are sponsor headline results, not a fully reviewed head-to-head paper. Failure to show non-inferiority is not itself a reported superiority test. The announcement does not supply detailed death or serious-event counts; none are invented.
