The study is focused on adult participants with heart failure that, in the opinion of the study doctor, have a clinical indication for right heart catheterization (RHC). The aim of the study is to evaluate the safety and tolerability of the study drug.\n\nThe study is looking at several other research questions, including:\n\n* What side effects may happen from taking the study drug\n* How much study drug is in the blood at different times\n* Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)', 'detailedDescription': 'Note: Group A has stopped enrolling and Group B will not enroll participants'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Key Inclusion Criteria:\n\n1.
