Rhea-AI Filing Summary

Contineum Therapeutics, Inc. reported that on December 8, 2025 it submitted details of its global Phase 2 clinical trial of PIPE-791 for idiopathic pulmonary fibrosis to the ClinicalTrials.gov Protocol Registration and Results System, with posting to follow PRS approval.

The 26-week, international, randomized, dose-ranging, double-blind, placebo-controlled study will evaluate once-daily PIPE-791 in about 324 IPF patients, focusing on safety and tolerability and the change from baseline in absolute forced vital capacity at week 26.

The company’s trial design and launch strategy draw on prior regulatory engagement and completed Phase 1 studies, and it expects to begin the trial internationally and add countries as regulatory approvals are obtained, with completion anticipated in June 2028.

Insights

Biotech clinical development analyst

Contineum advances PIPE-791 into a global Phase 2 IPF trial, but outcome, timing and approvals remain subject to significant clinical and regulatory risks.

Contineum Therapeutics has submitted details for a global Phase 2 trial of PIPE-791 in idiopathic pulmonary fibrosis to the ClinicalTrials.gov PRS on December 8, 2025. The planned 26-week, international, randomized, dose-ranging, double-blind, placebo-controlled study will test once-daily dosing in about 324 patients, assessing safety and tolerability and change from baseline in absolute forced vital capacity at week 26.

The company states that the trial design and launch strategy were informed by regulatory engagement on an earlier draft protocol and by completed Phase 1 clinical trials. It expects to start the trial internationally and add countries as regulatory approvals become available, with trial completion anticipated in June 2028, indicating a multi-year clinical program before pivotal data could emerge.

The forward-looking discussion highlights substantial risks, including the uncertainty of clinical drug development, the lengthy and unpredictable process for obtaining protocol and product approvals, the possibility that Phase 1 results may not predict Phase 2 outcomes, and risks from adverse side effects, third-party reliance, manufacturing, competition and funding sufficiency. Actual results for PIPE-791 and the IPF program will depend on how these factors evolve over the course of the planned Phase 2 trial.
