Extension Study to Evaluate the Long-Term Effects of ACE-083 in Patients With Facioscapulohumeral Muscular Dystrophy (FSHD) and Charcot-Marie Tooth (CMT) Disease Types 1 and X (CMT1 and CMTX)
Stopped: Investigation of ACE-083 for use in patients with CMT and FSHD is being discontinued in this extension study as functional secondary endpoints were not achieved in the A083-023 or A083-03 trial (the parent trials).

Plain-language summary
This is an open-label, multicenter, phase 2 extension study to evaluate the safety, tolerability, PK, PD, and efficacy of ACE-083 in subjects with FSHD previously enrolled in Study A083-02 and subjects with CMT1 and CMTX previously enrolled in Study A083-03. This study will be conducted in two Parts: Part 1, which is a loading phase of 6 months' duration, and Part 2, the maintenance phase, which will last up to 24 months.

Inclusion criteria
. Completion of treatment with study drug per protocol and completion of the end of treatment (ET) visit in Study A083-02 or Study A083-03.
. Females of childbearing potential (defined as sexually mature women who have not undergone hysterectomy or bilateral oophorectomy or are not naturally postmenopausal ≥ 24 consecutive months) must have negative urine pregnancy test prior to enrollment and use highly effective birth control methods (abstinence, oral contraceptives, barrier method with spermicide, or surgical sterilization) during study participation and for 8 weeks following the last dose of ACE-083. Hormonal birth control use must be stable for at least 14 days prior to Day 1. Males must agree to use a condom during any sexual contact with females of childbearing potential while participating in the study and for 8 weeks following the last dose of ACE-083, even if they have undergone a vasectomy. Subjects must be counseled about contraception prior to the first dose of ACE-083 and every three months thereafter during the study.
. Ability to adhere to the study visit schedule/procedures and to understand and comply with protocol requirements
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
