NCT ID NCT07426419

First seen Jun 26, 2026 · Last updated Jul 01, 2026 · Updated 3 times

Summary

This early-stage trial tests a single intravenous dose of AFTX-201, a gene therapy designed to deliver a working copy of the BAG3 gene to heart cells. It enrolls 22 adults aged 18–55 with dilated cardiomyopathy and a BAG3 mutation. The study primarily checks safety and tolerability over 12 months, while also measuring changes in heart function and biomarkers.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

AFTX-201 (gene therapy)

What this could lead to

If successful, this could point toward a one-time gene therapy treatment to improve heart function in people with BAG3-related dilated cardiomyopathy.

What could go wrong

This is an early Phase 1/2 trial with only 22 participants, so safety and effectiveness are not yet proven. Gene therapies can have unexpected side effects, and long-term benefits are uncertain.
