Filter by:This is a randomized, double-blind, placebo-controlled Phase 2 study evaluating oral administration of CAD-1883 in the treatment of adults with a genotypic diagnosis of Spinocerebellar Ataxia (SCA). This study offers the opportunity to understand the safety, tolerability, and efficacy of CAD-1883 in the SCA patient population.
DESIGN: Pilot, Phase II, double-blind, placebo-controlled study JUSTIFICATION: In the literature one does not find a pharmacological treatment that changes the natural history of Spinocerebellar ataxtia type 3 (SCA3). Patients with this disease invariably become dependent. OBJECTIVES I. To determine safety and tolerability of phenylbutyrate in patients with SCA3. II. To provide early subsidies on the efficacy of phenylbutyrate in SCA3. DURATION: 12 months of a double-blind study. PLACE OF REALIZATION: Hospital de Clínicas de Porto Alegre, Brazil. NUMBER OF PATIENTS: 20 patients. CONCOMITANT MEDICATIONS: There are no concomitant medications that are prohibited unless they affect safety parameters of this study (hemogram and platelets; fasting serum glucose, AST, ALT, Gamma-GT, Bilirubins, Prothrombin time, Creatinine, Urea, Na, K, chlorides and arterial gasometry; electrocardiogram and echocardiogram). MEDICATIONS UNDER INVESTIGATION: Powdered sodium phenylbutyrate in sachets containing each 3g. At the start of the study, the dose will be 15g/day (five sachets) and may be reduced in case of mild adverse events. OUTCOMES Primary safety outcome: The number of adverse events, interruptions and dose reductions in the two groups (cases and controls). Efficacy outcomes: Efficacy outcomes are the following scores in both groups: NESSCA, SARA, Barthel, BDI, and WHOQol.
