Brief Summary
The objective of the CAPACITY-HFpEF study is to evaluate the safety and efficacy of IW-1973 compared with placebo when administered daily for approximately 12 weeks to patients with HFpEF. The study will evaluate the effect of oral IW-1973 on peak exercise capacity in patients with HFpEF, with or without permanent or persistent atrial fibrillation.

Outcome Measures
Primary Outcomes (2)
Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Study Drug-related TEAEs
An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. TEAEs are defined as those adverse events (AEs) that started or worsened in severity after the administration of study drug. Causality relationship to study drug was per Investigator assessment. Number of participants with TEAEs and study drug-related TEAEs is presented.
Day 1 up to Day 113
Change From Baseline in Peak Oxygen Consumption (VO2) at Week 12
Peak VO2 was obtained from Cardiopulmonary Exercise Test (CPET), which was used to evaluate the effect of praliciguat on peak exercise capacity. Baseline is defined as the last non-missing measurement prior to the first dose of study drug. Change from Baseline was calculated by subtracting Baseline value from the Week 12 value. Data were analyzed using an analysis of covariance (ANCOVA) model with treatment group and atrial fibrillation stratification factors as categorical variable terms and Baseline peak VO2 value as a covariate. Milliliter O2 per kilogram per minute = mL O2/kg/min

Limitations and Caveats
Due to changes in study objectives and design (protocol amendment 3), all efficacy analyses was performed using only the praliciguat 40 mg and placebo groups; the praliciguat 10 mg and 20 mg groups were excluded from all efficacy analysis. For completeness, participants treated with both 10 mg and 20 mg praliciguat are included in the AE summaries for safety analyses, as well as for Participant Flow and Baseline Characteristics.
