Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety and tolerability of IMB-1018972 as measured by incidence and severity of treatment emergent AEs (including AEs leading to study drug discontinuation and AEs leading to death), as well as incidence of treatment emergent SAEs		Baseline through Week 14 Safety Follow-up
Secondary	Change from baseline of peak oxygen consumption (VO2) and Oxygen uptake efficiency slope (OUES), measured by standardized cardiopulmonary exercise testing (CPET)		Baseline, Week 12
