Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in peak VO2 as measured by cardiopulmonary exercise test (CPET)	The primary analysis will assess the effect of LCZ696 on the change from baseline in peak VO2 (ml/kg/min) at week 50 compared to placebo, where baseline peak VO2 will come from the screening/baseline CPET.	Baseline to 50 weeks
