Current Primary Outcome Measures (submitted: October 18, 2021)

Time to First Occurrence of Composite Endpoint of Cardiovascular (CV) Death or Heart Failure (HF) Hospitalization [ Time Frame: From date of randomization until the date of first occurrence of a CV death or HF hospitalization, assessed up to approximately 40 months ]

The first event of CV death or HF hospitalization as confirmed by a clinical events committee (CEC).

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: October 18, 2021)

• Time to First Occurrence of CV Death [ Time Frame: From date of randomization until the date of first occurrence of a CV death, assessed up to approximately 40 months ]
  The first event of CV death as confirmed by a CEC.
• Time to First Occurrence of HF Hospitalization [ Time Frame: From date of randomization until the date of first occurrence of a HF hospitalization, assessed up to approximately 40 months ]
  The first event of HF hospitalization as confirmed by a CEC.
• Time to Total HF Hospitalizations (Including First and Recurrent Events) [ Time Frame: Up to approximately 40 months ]
  All events of HF hospitalization as confirmed by a CEC.
• Time to First Occurrence of Composite Endpoint of All-Cause Mortality or HF Hospitalization [ Time Frame: From date of randomization until the date of first occurrence of death or HF hospitalization, assessed up to approximately 40 months ]
  The first event of death due to any cause or HF hospitalization as confirmed by a CEC.
• Time to All-Cause Mortality [ Time Frame: From date of randomization until the date of death, assessed up to approximately 40 months ]
  The first event of death due to any cause as confirmed by a CEC.
• Percentage of Participants who Experienced One or More Selected Nonserious Adverse Events (NSAEs) [ Time Frame: Up to approximately 40 months ]
  An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Selected NSAEs are nonserious AEs that meet any of the following criteria: AEs that lead to study intervention dose modification or discontinuation, AEs that lead to withdrawal from the study, or coronavirus disease (COVID-19) disease-related AEs.
• Percentage of Participants Who Experienced One or More Serious Adverse Events (SAEs) [ Time Frame: Up to approximately 40 months ]
  An SAE is defined as any untoward medical occurrence that, at any dose: Results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is another important medical event, as judged medically or scientifically, that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed above.
• Percentage of Participants Who Experienced One or More Events of Clinical Interest (ECIs) [ Time Frame: Up to approximately 40 months ]
  Events of clinical interest will include: 1) Potential drug-induced liver injury (DILI) events defined as: elevated aspartate aminotransferase (AST) or alanine aminotransferase (ALT) laboratory value that is greater than or equal to 3X the upper limit of normal (ULN) and an elevated total bilirubin laboratory value that is greater than or equal to 2X the ULN and, at the same time, an alkaline phosphatase laboratory value that is less than 2X the ULN, as determined by way of protocol specified laboratory testing or unscheduled laboratory testing, 2) Symptomatic hypotension 3) Anemia.

Descriptive Information

• Brief Title: A Study of Vericiguat (MK-1242) in Participants With Chronic Heart Failure With Reduced Ejection Fraction (HFrEF) (MK-1242-035)
• Official Title: A Pivotal Phase 3 Randomized, Placebo-controlled Clinical Study to Evaluate the Efficacy and Safety of the sGC Stimulator Vericiguat/MK-1242 in Adults With Chronic Heart Failure With Reduced Ejection Fraction
• Brief Summary: The purpose of this study is to evaluate the efficacy and safety of vericiguat in participants with chronic heart failure with reduced ejection fraction (HFrEF), specifically those with symptomatic chronic HFrEF who have not had a recent hospitalization for heart failure or need for outpatient intravenous (IV) diuretics. The primary hypothesis is that vericiguat is superior to placebo in reducing the risk of cardiovascular death or heart failure hospitalization.
