Summary

This study looked at how a single dose of a drug called INCB123667 moves through and leaves the bodies of 9 healthy men. The drug was tagged with a tiny amount of radioactivity to track it in blood, urine, and stool. The goal was to understand how the drug is processed and eliminated, not 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: * Ability to comprehend and willingness to sign a written ICF for the study. * Healthy males age 18 to 55 years, inclusive, at the time of signing the ICF. * Body mass index between 18.0 and 32.0 kg/m2, inclusive, at the time of screening. * No clinically significant findings in screening evaluations (eg, clinical, laboratory, vital signs, ECG). Tests with results that fail eligibility requirements may be repeated once during screening if the investigator believes the results to be in error. * Ability to swallow and retain oral medication. Exclusion Criteria: * History of clinically significant respiratory, renal, GI, endocrine, hematopoietic, psychiatric, and/or neurological disease. * History of cardiovascular, cerebrovascular, peripheral vascular, or thrombotic disease or uncontrolled hypertension (systolic blood pressure \> 140 mmHg or diastolic blood pressure \> 90 mmHg at screening, confirmed by repeat testing). * Presence of a malabsorption syndrome (eg, Crohn's disease or chronic pancreatitis) that could possibly affect drug absorption. * Current or recent (≤ 6 months of screening), clinically significant gastrointestinal disease or surgery or any history of GI surgery (including cholecystectomy, excluding appendectomy and uncomplicated hernia repair) that is anticipated to affect the absorption of the study drug. * Any major surgery within 6 months (≤ 6 months) of screening. * Donation of blood to a blood bank or participation in a clinical study (except a screening visit) within 4 weeks of screening (within 2 weeks for donation of plasma only). * Positive test for HBV, HCV, or HIV. Participants whose HBV results are compatible with prior immunization or immunity due to infection may be included at the discretion of the investigator. * History of significant alcohol use within 3 months of screening, defined as regular alcohol consumption \> 21 units per week for males (1 unit = 0.5 pint of beer or a 25-mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine, depending on type). * Positive urine or breath test result for ethanol or positive urine or serum screen for drugs of abuse that are not otherwise explained by permitted concomitant medications or diet. * Current treatment or treatments within 30 days or 5 half-lives (whichever is longer) before the first dose of study drug on Day 1 with another investigational medication, or current enrollment in another investigational drug study. * Participation in more than 3 radiolabeled drug studies in the last 12 months (previous study in which exposures are known to the investigator to be at least 4 months prior to check-in \[Day -1\]; previous studies in which exposures are not known to the investigator to be at least 6 months prior to check-in \[Day -1\]). * Exposure to significant diagnostic or therapeutic radiation (eg, serial x-ray, computed tomography scan, barium meal) or employment in a job requiring radiation exposure monitoring within 12 months prior to check-in. * Current treatment or treatment within 15 days or 5 half-lives (whichever is longer) before the first dose of study drug with any medications known to be an inducer or potent inhibitor of CYP3A4, BCRP, or P-gp (refer to the Certara Drug Interaction Database Program for prohibited medications). * History of tobacco- or nicotine-containing product use within 1 month of screening. However, use of nicotine-containing products that is equivalent to ≤ 2 cigarettes per week may be permitted at the discretion of the investigator. Other protocol-defined Inclusion/Exclusion Criteria may apply.
