Condition/Disease

Nonalcoholic Steatohepatitis

Objectives

This study will evaluate the effect of each dose of MK-3655 versus placebo on the percentage of individuals with NASH resolution without worsening of fibrosis after 52 weeks. The primary hypothesis of the study is that at least 1 dose of MK-3655 is superior to placebo with respect to the percentage of individuals with NASH resolution without worsening of fibrosis after 52 weeks.

Endpoints

Primary Outcome Measures :
Participants With Nonalcoholic Steatohepatitis (NASH) Resolution Without Worsening of Fibrosis After 52 Weeks [ Time Frame: Week 52 ]
The NASH CRN scoring system evaluated by Blinded Independent Central Review [BICR] is used to assess treatment response. The NASH CRN scoring scales are: lobular inflammation score (0-3); hepatocyte ballooning score (0-2); steatosis score (0-3); and fibrosis score (0-4). NASH resolution is defined as a score of 0-1 for inflammation, 0 for ballooning, and any grade of steatosis.

Participants Who Experienced an Adverse Event (AE) [ Time Frame: Up to 56 weeks ]
An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.

Participants Discontinuing Study Medication Due to an AE [ Time Frame: Up to 52 weeks ]
An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.
