研究概览
简要总结
The purpose of this study is to investigate the effect of CK-2127107 versus placebo on skeletal muscle fatigue assessed as change from baseline versus 14 days of treatment in sum of peak torque during isokinetic knee extensions.
This study will also assess the effects of CK-2127107 on physical performance via a short physical performance battery (SPPB), stair-climb test and 6 minute walk test.
详细描述
Enrolled participants will be randomized to receive either CK-2127107 or Placebo first and then will be crossed over to receive the opposite intervention. The study will consist of two treatment periods of 14 days separated by a washout period of 14 days.
