Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford

The Coordination of Rare Diseases at Sanford (CoRDS) is an international patient registry that serves as a centralized resource for rare disease research. Individuals affected by rare diseases, undiagnosed conditions, and disorders of unknown prevalence may voluntarily contribute health information to support natural history studies, participant recruitment, and other research efforts. Through partnerships with patient advocacy organizations and researchers worldwide, CoRDS helps connect rare disease communities with research opportunities while advancing knowledge across more than 7,000 rare diseases. Participation is free of charge.

Natural History and Advanced Genetic Study of Pyruvate Dehydrogenase Complex Deficiencies

Children and adults with pyruvate dehydrogenase complex deficiency (PDCD) are participating in a research study seeking to better understand the genetic causes, symptoms, usefulness of current treatments, and outcomes for these disorders. The research project involves completing a questionnaire about the individual or family's medical history and experiences with PDCD, review of medical records by the researchers, and in some cases, advanced genetic testing.

Efficacy and Safety of the Treatment of Pyruvate Dehydrogenase Deficiency Patients With Glycerol Phenylbutyrate (RAVICTI)

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.
