Safety and drug levels of BMS-986521 in healthy adults

A Phase 1, Randomized, Placebo-Controlled, Double-Blind, First-in-Human Study Evaluating Safety, Tolerability, and Pharmacokinetics of Single and Multiple Ascending Doses of Orally Administered BMS-986521 in Healthy Adult Participants

Phase 1 Interventional Bristol-Myers Squibb · NCT07283263

This trial will test how safe and tolerable BMS-986521 is in healthy adults, measure drug levels after single and multiple doses, and see if food affects those levels.

What this trial studies

This Phase 1 trial enrolls healthy adult volunteers to receive single and multiple ascending doses of BMS-986521 or placebo to determine safety, tolerability, and pharmacokinetics. Participants must pass screening including medical history, physical exam, ECG, and laboratory tests and meet BMI and weight requirements. Specific cohorts will examine potential food effects on drug exposure and one cohort may include participants with stable cardiovascular conditions if suitable. Dosing and monitoring occur at a single clinical research site in Anaheim, California.

Who should consider this trial

Good fit: Healthy adults who are not of childbearing potential, weigh at least 50 kg, have a BMI between 18 and 32 kg/m², and have no clinically significant medical abnormalities are ideal candidates, with limited inclusion of stable cardiovascular conditions in a specified cohort.

Not a fit: People with significant medical conditions, a history of rhabdomyolysis or certain cancers, those of childbearing potential, or anyone seeking direct therapeutic benefit should not expect clinical benefit from participating.

Why it matters

Potential benefit: If successful, this work could provide early safety and dosing information that helps guide later studies which may lead to effective treatments for patients.

How similar studies have performed: This is a standard healthy-volunteer Phase 1 safety and pharmacokinetic design that has been used successfully to establish dosing for many investigational drugs, although outcomes for BMS-986521 itself are not yet known.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Participants must be healthy males and females (assigned at birth) who are not of childbearing potential, with no clinically significant abnormalities in medical history, physical exam, ECG, or lab tests.
* Participants must have a body mass index (BMI) between 18 and 32 kg/m² (inclusive) and body weight of at least 50 kg.
* For Part B/Cohort 11 only: participants with stable cardiovascular conditions may be included if deemed suitable by the investigator.

Exclusion Criteria:

* Participants must not have any significant medical condition or history (renal, hepatic, hematologic, GI, endocrine, pulmonary, neurologic, or immunologic) that may affect drug absorption, distribution, metabolism, or excretion (ADME), or pose a risk to the participant.
* Participants must not have a history of rhabdomyolysis, cancer (except certain cured skin or cervical cancers), hematologic malignancy, or myelodysplastic syndrome.
* Participants must not have recent or current significant GI disease, major surgery, or medical interventions affecting ADME (except appendectomy or cholecystectomy).
* Participants must not have had a blood transfusion within 4 weeks or have an inability to tolerate oral medication or venous access.
* Other protocol defined inclusion/exclusion criteria apply.
