A Study to Assess the Safety and Effectiveness of FLX-787 in Subjects With Charcot-Marie-Tooth Disease Experiencing Muscle Cramps
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study
The COMMIT Study will assess the safety and effectiveness of FLX-787 in men and women with Charcot-Marie-Tooth disease (CMT) experiencing muscle cramps. Participants will be asked to take two study products during the course of the study. One of these study products will be a placebo. Approximately 120 participants in 20 study centers across the United States are expected to take part. Participants will be in the study for approximately 3 months and visit the study clinic 3 times.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.See eligibility criteria
- Presence of symptoms of CMT since at least 6 months prior to Screening, and confirmed diagnosis of CMT as defined by:
- Genetic confirmation of a mutation known to cause CMT, or
- Clinical and electrophysiological evidence of CMT and a genetic confirmation in a family member. Clinical features include length dependent sensory and motor loss, with sensorimotor axonal or demyelinating changes on a nerve conduction study.
- Weekly muscle cramping (defined as: a sustained muscle contraction that's most often painful and lasts seconds to minutes)
- Presence of major gastrointestinal disorders, such as inflammatory bowel disease, diverticulitis, active peptic ulcer disease, or significant gastroesophageal reflux disease (i.e., not well-controlled on antacids or proton pump inhibitors), or oral or esophageal lesions/ulcers
- Presence of significant swallowing problems
- Unable or unwilling to discontinue medications for cramps and/or opiates
- Inability to tolerate a spicy sensation in the mouth or stomach
- Actively using illicit drugs or history of chronic substance abuse within the past year prior to screening, including abuse of alcohol
- Intention to change the current level of tobacco use or use of nicotine-containing products (i.e., new smokers or those actively trying to quit may not enrolled)
- Participated in a clinical study (except natural history studies without administration of an investigational product) within 30 days prior to screening
