Clinical Trial Summary

The purpose of this study was to assess the effect of CK-2127107 (hereafter referred to as reldesemtiv) versus placebo on respiratory function and other measures of skeletal muscle function in patients with ALS.


Clinical Trial Description

This was a double-blind, randomized, placebo-controlled, dose ranging study of reldesemtiv in patients with ALS. Eligible patients were randomized (1:1:1:1) to receive placebo or one of three doses of reldesemtiv (150, 300, or 450 mg twice daily) for 12 weeks. Randomization was stratified by riluzole concomitant use/non-use and edaravone concomitant use/non-use. Concomitant riluzole and edaravone were allowed as long as the riluzole dose had been stable for at least 30 days prior to screening and edaravone had been taken for 2 cycles prior to screening; these drugs could not be initiated during the study.

A total of 7 study visits were planned: screening, Day 1 (first dosing day), Weeks 2, 4, 8, and 12, and follow-up (4 weeks after the last dose of study drug). Study drug (placebo or reldesemtiv) was to be taken twice daily, approximately 12 hours (± 2 hours) apart and within 2 hours following a meal. ;
