Full Description

A screening period of up to 29 days will be used to assess participants' eligibility. This study will consist of 2 cohorts. Cohort 1 will include participants on stable therapies of ACEi/ARB and beta-blockers, in addition to other standard of care medications. Cohort 2 will consist of participants treated with sacubitril/valsartan and beta-blockers, in addition to other standard of care medications.

For Cohort 1 participants will be randomized in a 2:1 ratio to receive a single dose of subcutaneous (s.c) XXB750 or placebo. For Cohort 2, participants will be randomized in a 3:1 ratio to receive three doses of either s.c. XXB750 or placebo.

Cohort 1: After an initial domiciling period following study drug administration, participants will be followed for 13 weeks post-dosing for safety, tolerability and PK until the End of Study visit on Day 91.

Cohort 2: After a domiciling period following first study drug administration of XXB750 or placebo, participants will be followed for 27 days post dosing for safety, tolerability and PK. On Day 28, participants will be re domiciled and receive a second dose of either XXB750 or placebo. Participants will be followed for another 27 days post-dosing for safety and tolerability. On Day 56, participants will be re-domiciled and receive a third dose of either XXB750 or placebo. After the third domiciling period, participants will be followed for 13 weeks post-dosing for safety, tolerability and PK until the End of Study visit on Day 146.
