Statistical methods / analysis
The sample size minimum of 6 and up to 8 participants for each cohort is based on clinical considerations.
Results of each cohort (HFpEF and HFrEF) will be analysed descriptively. No formal statistical hypothesis will be tested in this study. In general, data will be summarised by cohort and/or pooled when appropriate, using descriptive statistics (mean, median, standard deviation, minimum and maximum) or frequency counts and percentages.
Baseline is defined as the last available, valid, non-missing assessment on or prior to the first dose of KER-012.
Statistical methodology will be included in the Statistical Analysis Plan, which will be finalised prior to any database lock.

Summary
Brief summary
This study is designed to evaluate the tolerability, safety, and pharmacodynamics of KER-012 in combination with current background therapy at a stable dose in participants with heart failure. Background therapy will be defined by the investigator as appropriate. HF background therapy treatments will be provided by the treating physician based on local treatment guidelines and must remain stable throughout the study. If a participant is observed to show disease progression requiring additional therapy, the participant should receive standard HF treatment following locally relevant guidelines.

This study will enroll a total of 12-16 heart failure patients with either preserved or reduced ejection fractions for subcutaneous injections with KER-012 every 4 weeks.

Heart Failure is associated with increased activin receptor type II signalling. KER-012 is designed to bind to activins and thereby, potentially reduce activin receptor type II signalling. Therefore, it is anticipated that KER-012 could potentially improve the underlying pathology of heart failure.
