Phase 2
Recruiting
Conditions
Left Ventricular Systolic Dysfunction
Heart Failure
Interventions
Drug: Placebo tablet
Drug: Placebo suspension
Registration Number
NCT05714085
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study aims to compare the efficacy of vericiguat versus placebo on change in n-terminal pro-brain natriuretic peptide (NTproBNP) from baseline to Week 16 of the Base Period. The primary hypothesis is that vericiguat is superior to placebo in reducing NT-proBNP at Week 16 of the Base Period.

Detailed Description

As of Protocol Amendment 2, the separate open-label extension arm of study MK-1242-043 (NCT06428383) will be incorporated into the present MK-1242-036 study as an extension period. Participants from the Base Period will be provided the opportunity to participate in the optional open-label Extension Period if eligible. After all ongoing participants are transferred into the extension period of MK-1242-036, MK-1242-043 (NCT06428383) will be formally closed.
