EU CTIS ID: 2023-509748-89-00
What this study is testing
To evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of ARO-DUX4 using escalating single and multiple doses in subjects with facioscapulohumeral muscular dystrophy Type 1 (FSHD1).
- Phase I and Phase II (Integrated)- First administration to humans
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
- Genetically confirmed FSHD1 (based on Screening evaluation or source verifiable medical record). If available, the number of repeats (1 to 10) via assessment of the size of the D4Z4 array on chromosome 4 should be provided. Confirmation must be obtained prior to the baseline muscle biopsy.
- Clinical severity score (CSS) between 3 and 8 (scale, 0 to 10)
- Must have an eligible lower extremity muscle for biopsy as determined from MRI by a central reader, with MFF ≥10% and less than approximately 40%.
- Males or nonpregnant, nonlactating females ≥18 years of age who do not plan to become pregnant during the study, with an upper age limit of ≤70 years.
- Able and willing to provide written informed consent prior to the performance of any study specific procedures.
- Subjects with a body mass index (BMI) between 18.0 and 35.0 kg/m2, inclusive. A subject with FSHD1 and a BMI outside this range may be allowed into the study at the discretion of the PI.
You likely can't join if
- Is unable to comply with the study requirements, including the number of required visits to the clinical site.
- Use of an investigational agent or device within 30 days (or longer as per local regulations) prior to dosing or current participation in an investigational study.
- Blood donation (500 mL) within 7 days prior to study treatment administration. Donation or loss of whole blood (excluding the volume of blood that will be drawn during the Screening procedures of this study) prior to administration of the study treatment as follows: 50 mL to 499 mL of whole blood within 30 days, or more than 499 mL of whole blood within 56 days prior to study treatment administration.
- Any concomitant medical or psychiatric condition or social situation that would make it difficult to comply with protocol requirements or put the subject at additional safety risk.
- Estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 calculated by using the Chronic Kidney Disease Epidemiology Collaboration creatinine equation (CKD-EPI).
- Current concomitant use of theophylline (including duration of study).
