FORTITUDE Trial Summary

This trial tests a new drug for FSHD to see if it's safe, works well, and is effective. It's a double-blind study, meaning neither the patient nor doctor knows who's getting the drug.

Who is the study for?
Adults with confirmed FSHD1 or FSHD2 who can walk at least 10 meters and have at least one muscle region suitable for biopsy. They should not be pregnant, breastfeeding, or planning pregnancy soon, must follow contraceptive guidelines, and have a BMI under 35.0 kg/m^2. Those with recent biopsies, bleeding disorders, severe muscle wasting, or conditions that could affect study participation are excluded.Check my eligibility
What is being tested?
The trial is testing AOC 1020 against a placebo in adults with Facioscapulohumeral Muscular Dystrophy (FSHD). It's randomized and double-blind meaning neither the participants nor the researchers know who gets the real treatment versus placebo. The study will assess safety, tolerability of doses given intravenously and any potential benefits on muscle function.See study design
What are the potential side effects?
While specific side effects of AOC 1020 aren't listed as it's likely being tested for the first time in humans (Phase 1/2), common side effects may include reactions at injection site, fatigue, headache or flu-like symptoms; more serious risks might involve allergic reactions or impacts on liver/kidney functions.
