AZD8965 in IPF: see if three doses help IPF patients
Official title: A Phase IIb Study to Evaluate the Efficacy, Safety, and Tolerability of AZD8965 in Participants With Idiopathic Pulmonary Fibrosis (IPF) (ARGiNAUT)
Run by AstraZeneca · NCT07652658 · Data updated 2026-11-12
This Phase IIb study tests three doses of AZD8965 against placebo in people with idiopathic pulmonary fibrosis, including those who are and aren’t on antifibrotic therapy.

Is this trial a fit for you?
✓Likely a good fit
Adults 40 years and older with IPF, either on a stable antifibrotic regimen or not on antifibrotic therapy, and with sufficiently preserved lung function.
✕Probably not a fit
Patients with other interstitial lung diseases, significant acute IPF events, or severe cardiovascular conditions may not benefit from this trial.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a randomized, double-blind, placebo-controlled study designed to compare three doses of AZD8965 with placebo over 24 weeks in about 360 adults with IPF. Participants may be on stable antifibrotic therapy or not receiving antifibrotic treatment. The trial will assess efficacy, safety, and tolerability, with results informing optimal dosing and tolerability in a diverse IPF population across ~200 sites globally. Eligible participants must have a diagnosis of IPF, adequate lung function, and no recent acute IPF events or major cardiovascular issues. Lead sponsor is AstraZeneca, with sites in Birmingham, AL and Phoenix, AZ.
Why it matters
Potential benefit: If successful, AZD8965 could offer an additional treatment option that may slow disease progression or improve symptoms for people with IPF.
How similar studies have gone: Early-stage trials in related fibrotic diseases have shown potential signals with similar approaches, but this specific AZD8965 IPF program is novel in its dosing and combination with antifibrotics.
