EU CTIS ID: 2024-512736-29-00
What this study is testing

- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- 1. FSHD1 subjects age 18-65 years.
- 10. Subject must complete the main study through the Week 60 visit in order to participate in the extension.
- 2. Subject will sign and date an informed consent form (ICF).
- 3. Subjects will have a confirmed diagnosis of FSHD1 with 1 to 9 repeats via assessment of the size of the D4Z4 array on chromosome 4 using the calculator provided by the sponsor. Genetic confirmation must be obtained prior to the screening MRI and baseline muscle biopsy; genetic confirmation can come from previous testing if verified with appropriate documentation. Due to stable transmission of repeat sizes within families, subjects with a clinical diagnosis of FSHD who have a first degree relative with a genetically confirmed diagnosis of FSHD1 may be entered into the study for screening and MRI. During screening, a confirmatory genetic diagnosis is conducted. If genetic testing during screening is necessary, the 4-week screening window will not start until the results are obtained and verified by the principal investigator.
- 4. Subject will be willing and able to comply with scheduled visits, treatment plan, study restrictions, laboratory tests, contraceptive guidelines, scheduled needle muscle biopsies, and other study procedures.
- 5. Male or female subjects: a. A female subject is eligible to participate if she is of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhoea or if of childbearing potential is using a highly effective method for avoidance of pregnancy (refer to Section 5.5) for the duration of the clinical trial and until 90 days following the last dose. The decision to include or exclude women of childbearing potential may be made at the discretion of the investigator and in accordance with local practice in relation to adequate contraception. b. Male subjects must agree to use one of the contraception methods listed in Section 5.5. This criterion must be followed from the time of the first dose of study medication until 90 days after the last study drug dose.
You likely can't join if
- 1. Subject has a history of any illness or any clinical condition that might confound the results of the study or pose an additional risk in administering study drug to the subject.
- 10. Vaccination with a live attenuated vaccine within 6 weeks of randomisation.
- 11. Subject has a history of alcohol, analgesic/opioid, and/or illicit drug abuse.
- 12. Subject has participated in a clinical trial in which they have received an investigational product 30 days prior to enrolment in the current study.
- 13. For subjects that are on drug(s) or supplements that may affect muscle function must be on a stable dose of that drug(s) or supplement for at least 3 months prior to enrolment in the study and remain on that stable dose.
- 14. Subject has a history of sensitivity to any of the study medications or components thereof, or a history of drug or other allergy that contraindicated their participation.
