A Study to Investigate the Safety, Tolerability, and Pharmacokinetics of BMS-986278 and the Effects of BMS-986278 on Cardiac Repolarization in Healthy Participants

October 1, 2025 updated by: Bristol-Myers Squibb

A Phase 1, Two-Part, Double-blind, Placebo-controlled, Randomized Study of the Safety, Tolerability, and Pharmacokinetics of BMS-986278 (Part A) and a Randomized, Double-blind, Positive-controlled, Placebo-controlled, 4-Period Crossover, Thorough QT/QTc Study to Evaluate the Effect of Multiple Doses of BMS-986278 on Cardiac Repolarization (Part B) in Healthy Participants

The purpose of this study is to determine the safety, tolerability, and pharmacokinetics (PK) of high dose of BMS-986278 in healthy participants and to assess the effect of BMS-986278 on the ECG intervals in healthy participants.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Female individuals not of childbearing potential (INOCBP) and males.
  • Healthy as determined by medical history, physical examination, vital signs, 12-lead ECG, and clinical laboratory assessments.
  • Body mass index (BMI) 18.0 to 32.0 kg/m2 , inclusive, for Parts A and B.

Exclusion Criteria:

  • Any significant acute or chronic medical illness as determined by the investigator.
  • History of clinically relevant cardiac disease as determined by the investigator, symptomatic or asymptomatic arrhythmias, presyncope or syncopal episodes, or additional risk factors for ventricular arrhythmias.
