New drug shows promise for rare movement disorder
NCT ID NCT02255435
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 2 times
Summary
This study tested a drug called RTA 408 (omaveloxolone) in 172 people with Friedreich's ataxia, a rare genetic disease that affects movement and coordination. The goal was to see if the drug is safe and can improve exercise ability and daily function. Participants took the drug or a placebo for up to 48 weeks, and researchers measured changes in cycling tests and a rating scale for movement.

Inclusion Criteria: 1. Have genetically confirmed Friedreich's ataxia 2. Have a modified FARS score ≥20 and ≤80 3. Be male or female and ≥16 years of age and ≤40 years of age 4. Have no changes to exercise regimen within 30 days prior to Study Day 1 and be willing to remain on the same exercise regimen during the 16-week study period 5. Have the ability to complete maximal exercise testing 6. Be able to swallow capsules Exclusion Criteria: 1. Have uncontrolled diabetes (HbA1c \>11.0%) 2. Have B-type natriuretic peptide value \>200 pg/mL 3. Have a history of clinically significant left-sided heart disease and/or clinically significant cardiac disease 4. Have known active fungal, bacterial, and/or viral infection, including human immunodeficiency virus or hepatitis virus (B or C) 5. Have known or suspected active drug or alcohol abuse 6. Have clinically significant abnormalities of clinical hematology or biochemistry, including but not limited to elevations greater than 1.5 times the upper limit of normal of aspartate aminotransferase, or alanine aminotransferase 7. Have any abnormal laboratory test value or serious pre-existing medical condition that, in the opinion of the investigator, would put the patient at risk by study enrollment 8. Have taken any of the following drugs within 7 days prior to Study Day 1 or plan to take any of these drugs during the time of study participation: 1. Sensitive substrates for cytochrome P450 2C8 or 3A4 (e.g., repaglinide, midazolam, sildenafil) 2. Moderate or strong inhibitors or inducers of cytochrome P450 3A4 (e.g., carbamazepine, phenytoin, ciprofloxacin, grapefruit juice) 3. Substrates for p-glycoprotein transporter (e.g., ambrisentan, digoxin) 9. Have participated in any other interventional clinical study within 30 days prior to Study Day 1 10. Have a cognitive impairment that may preclude ability to comply with study procedures 11. Prior participation in a trial with omaveloxolone (RTA 408)
