Efficacy and Safety of Tazbentetol in ALS Participants
brief summary
The objectives of this study are to examine the effects of tazbentetol on clinical measures of ALS, patient reported outcomes (PROs), long-term safety and tolerability.
detailed description
This is a Phase 2B/3 adaptive design randomized, double-blind, placebo-controlled (DBPC) study to evaluate the efficacy, safety and tolerability of tazbentetol administered orally in participants with ALS.
The study consists of 2 parts, as follows
Phase 2 double-blind, placebo controlled (DBPC): Randomized, double-blind, placebo-controlled study. Participants will be randomized to receive tazbentetol or placebo for 36 weeks.
Phase 3 double blind, placebo controlled (DBPC): Randomized, double-blind, placebo-controlled study. Participants will be randomized to receive the dose determined from Phase 2 or placebo for 36 weeks.
Open-label extension: Eligible participants who complete 36 weeks in the DBPC of either Phase 2 or Phase 3 will be offered to enroll into the OLE, starting at the corresponding DBPC Week 36 visit, and receive tazbentetol for 36 weeks. The dose for this extension will be based on data from DBPC phases.
