What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Clinically Significant Effects	Clinically significant effects are defined as treatment emergent adverse events (TEAEs) which in the opinion of the investigator are thought to be possibly related to study drug. A summary of serious and all other non-serious adverse events (whether or not related to study drug) is located in the Reported Adverse Events module.	Baseline to study completion (up to 135 days)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics, Maximum Concentration (Cmax)		Single Dose:Day 1:Predose,10 minutes before end,2,6,12,24,48,192,360,528,696,1032,1368and2040 hours(hrs)Postdose;Multiple Dose:Day 1:Predose,24,48,96,168,264,360,528,696,1032hrs Postdose; Day57:Predose,24,48,96,168,336,672and1680hrs Postdose
Pharmacokinetics, Area Under the Concentration Versus Time Curve (AUC)	Area under the concentration curve (AUC) time zero to infinity (0-inf) was calculated for single dose administration and AUCtau (AUCτ) at steady state was calculated for multiple dose administration.	Single Dose:Day 1:Predose,10 minutes before end,2,6,12,24,48,192,360,528,696,1032,1368and2040 hours(hrs)Postdose;Multiple Dose:Day 1:Predose,24,48,96,168,264,360,528,696,1032hrs Postdose; Day57:Predose,24,48,96,168,336,672and1680hrs Postdose
Pharmacokinetics, Time of Maximum Observed Drug Concentration (Tmax)		Single Dose:Day 1:Predose,10 minutes before end,2,6,12,24,48,192,360,528,696,1032,1368and2040 hours(hrs)Postdose;Multiple Dose:Day 1:Predose,24,48,96,168,264,360,528,696,1032hrs Postdose; Day57:Predose,24,48,96,168,336,672and1680hrs Postdose
Percentage Change in Thigh Muscle Volume	Thigh muscle volume was determined by Magnetic Resonance Imaging (MRI) scan of the right leg thigh muscle. Percentage change in thigh muscle volume=(time point value-baseline value)*100. Change from baseline for muscle volume was analyzed using mixed model repeated measures (MMRM) model with fixed effects of treatment, time and treatment*time interaction and a random effect of subject where baseline values were included as a covariate.	Baseline, Day 22 for a single dose arm/ baseline, Days 22 and 71 for multiple dose arms
