Efficacy, Safety, and Pharmacokinetics of Vericiguat in Pediatric Participants With Heart Failure Due to Left Ventricular Systolic Dysfunction (MK-1242-036)

Официальное название

A Phase 2/3 Randomized, Placebo-Controlled, Double-blind, Clinical Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of Vericiguat in Pediatric Participants With Heart Failure Due to Systemic Left Ventricular Systolic Dysfunction (VALOR)

Обзор

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.

Подробное описание

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.
