First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed Phase 1 study gave six healthy men a single oral dose of varegacestat containing a tiny radioactive tracer. Researchers measured how much of the drug appeared in blood, urine, and feces to understand how the body absorbs, breaks down, and eliminates it. The study did not aim to treat any disease.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Be a male participant between 18 and 55 years of age, inclusive, at Screening. * Medically healthy based on the absence of clinically significant abnormal vital sign measurements, clinical laboratory test results (especially tests for renal and hepatic function), resting 12-lead Electrocardiogram (ECG) evaluation, and physical examination, as determined by the Investigator at Screening and the Check-In visit. Exclusion Criteria: * Have taken an investigational drug or participated in a clinical trial evaluating an investigational drug or device within 30 days (or 5 half-lives) prior to the study drug dose, whichever is longer. * Have participated in a radiolabeled drug study or have been otherwise exposed to significant diagnostic (excluding dental X-rays), therapeutic, or occupational radiation, where exposure is made known to the Investigator, within one year prior to admission to the clinic for this study. The total estimated 12-month exposure to radio material or ionizing radiation should be below the CFR recommended levels considered safe (per US Title 21 CFR 361.1) or below 3000 mrem. * Any condition which, in the opinion of the Investigator and/or Sponsor, would jeopardize participant safety or compliance with the Protocol.
