A Study Assessing the Mass Balance, Pharmacokinetics, and Metabolite Profiles of a Single Oral Dose of [14C]INCB099280 in Healthy Male Participants

An Open-Label Study Assessing the Mass Balance, Pharmacokinetics, and Metabolite Profiles of a Single Oral Dose of [14C]INCB099280 in Healthy Male Participants

This study is being conducted to assess the Mass Balance, Pharmacokinetics, and Metabolite Profiles of a Single Oral Dose of [14C]INCB099280 in Healthy Male Participants.

Inclusion Criteria:

• Ability to comprehend and willingness to sign a written ICF for the study.
• Healthy males, as determined by the investigator based upon physical examinations, ECGs, vital signs, and safety laboratory assessments, aged 35 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, and ECG) at screening and Day -1.
• Ability to swallow and retain oral medication.

Exclusion Criteria:

• History of clinically significant respiratory, renal, gastrointestinal, endocrine, hematopoietic, psychiatric, and/or neurological disease as judged by the investigator.
• History of cardiovascular, cerebrovascular, peripheral vascular, or thrombotic disease or uncontrolled hypertension (systolic blood pressure > 140 mm Hg 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 (within 6 months before screening), clinically significant, gastrointestinal disease or surgery (including cholecystectomy, excluding appendectomy) that could affect the absorption of study drug.
• Any major surgery within 6 months of screening.
• Donation of blood to a blood bank or in a clinical study (except a screening visit) within 3 months before screening (within 2 weeks for plasma donation).
• Positive test for HBV, HCV, or HIV at screening. Participants whose HBV results are compatible with prior immunization or immunity due to infection may be included at the discretion of the investigator.
• Regular alcohol consumption > 21 units per week (1 unit = 8 oz of beer or a 25-mL shot of a 40% spirit; 1.5 to 2 units = a 125-mL glass of wine, depending on type).
• Positive breath test for alcohol or positive urine screen for drugs of abuse (confirmed by repeat) at screening or admission (Day -1).
• Treatment with another investigational medication within 90 days or 5 half-lives (whichever is longer) before Day 1 or current enrollment in another investigational drug study.
• Participation in any clinical study involving a 14C-radiolabeled investigational product within 12 months prior to admission (Day -1).
• Radiation exposure, including that from the present study, excluding background radiation but including diagnostic x-rays and other medical exposures, exceeding 5 mSv in the last 12 months or 10 mSv in the last 5 years. No occupationally exposed worker, as defined in the Ionising Radiation Regulations 2017, shall participate in the study.
• History of tobacco- or nicotine-containing product use within 1 month before screening. Consumption of tobacco- or nicotine-containing products 72 hours before admission (Day -1) until CRU discharge is not permitted. Breath test for carbon monoxide > 10 ppm (confirmed by repeat) at screening or admission (Day -1).
• Use of prescription drugs within 14 days before Day 1 or nonprescription medications/products (including vitamins, minerals, and phytotherapeutic, herbal, or plant-derived preparations) within 7 days before Day 1 until CRU discharge. However, paracetamol up to 4000 mg Q24H and ibuprofen up to 600 mg Q24H are permitted.

Other protocol-defined Inclusion/Exclusion Criteria may apply.
