Inclusion criteria
. Male subject aged 18 to 45 years at screening visit.
. Subject has FXS with a molecular genetic confirmation of the full fragile X mental retardation-1 (FMR1)mutation (≥200 CGG repetitions).
. Subject is able to swallow capsules.
. Current treatment with ≤3 prescribed psychotropic medications. Anti-epileptic medications are permitted and are not counted as psychotropic medications if they are used for the treatment of seizures. Anti-epileptics for other indications, such as the treatment of mood disorders, count towards the limit of permitted medications.
. Permitted concomitant psychotropic medications must be at a stable dose and dosing regimen for at least 4 weeks prior to screening and must remain stable during the period between screening and the commencement of the study treatment.
. Anti-epileptic medications must be at a stable dose and dosing regimen for 12 weeks prior to screening and must remain stable during the period between screening and commencement of the study treatment.
. Subjects with a history of seizure disorder who are currently receiving treatment with anti-epileptics must have been seizure free for 3 months preceding screening or must be seizure free for 2 years if not currently receiving anti-epileptics.
Exclusion criteria
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.
What they're measuring
1
National Institutes of Health Toolbox Cognitive Battery cognition crystallized composite score (NIH-TCB CCC)
. Subject must be willing to practice barrier methods of contraception while on the study if sexually active. Abstinence is also considered a reasonable form of birth control in this study population.
0. Subject has a parent, legal authorized guardian, or consistent caregiver.
1. Subject and caregiver are able to attend the clinic regularly and reliably.
2. If subject is his own legal guardian, he is able to understand and sign informed consent to participate in the study.
3. For subjects who are not their own legal guardian, subject's parent/legally authorized guardian is able to understand and sign an informed consent form for their child to participate in the study.
4. If subject is not his own legal guardian, subject must provide assent for participation in the study if he has the cognitive ability to do so.
. Inability to successfully complete the NIH-TCB picture vocabulary and oral reading assessments at screening and baseline. The ability to complete the NIH-TBC oral reading and picture vocabulary subtest at baseline is defined as the ability to complete both subtests, with (1) confirmation from the clinician administering that the test administrations are valid (noted on the administration form) and (2) generation of valid test scores for each test.
. History of or current cardiovascular, renal, hepatic, respiratory, gastrointestinal, psychiatric, neurologic, cerebrovascular, or other systemic disease that would place the subject at risk or potentially interfere with the interpretation of the safety, tolerability, or efficacy of the study treatment.
