What to Expect as a Participant
You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.
In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.
This trial targets 15 participants in total. It began in 2025-10-01 with a primary completion date of 2026-04-01.

Brief Summary
This is a phase II, multicenter, prospective, non-comparative clinical trial to assess the efficacy and safety of the treatment of pyruvate dehydrogenase deficiency (PDH) patients with glycerol phenylbutyrate (Ravicti®). The trial will be conducted with three visits: 3 day hospitalizations including clinical consultations and paramedical procedures at Month 0 (M0), Month 3 (M3), Month 6 (M6). During all the research, AE/SAE and treatment compliance will be recorded. Patients will keep their usual treatment during the study time: vitamin B1, ketogenic diet, possible anti-epileptic and/or dystonic treatment(s). The efficacy on fatigue, polyhandicap, neurodevelopmental functioning, quality of life and seizure amount for epileptic patients will be evaluated at 0, 3 and 6 months. Biological balance will be assed with regular quantification of PDH deficiency markers, lactate concentration and amino acid plasma quantification.
