A Study of the Absorption, Metabolism, and Excretion of [14C]-SKI-O-703 Following a Single Oral Dose in Healthy Male Subjects

Completed · Early Phase 1

Conditions studied: Healthy Volunteers

In brief

This will be a Phase I, open-label, nonrandomized, single dose study in healthy male subjects. Potential subjects will be screened to assess their eligibility to enter the study within 28 days prior to the dose administration. Subjects will be admitted into the study site on Day -1 and be confined to the study site until at least Day 8. On the morning of Day 1, all subjects will receive a single oral dose of \[14C\]-SKI-O-703. Subjects will be discharged if the following discharge criteria are met: plasma radioactivity levels below the limit of quantitation for 2 consecutive collections, ≥ 90% mass balance recovery, and ≤ 1% of the total radioactive dose is recovered in combined excreta (urine and feces) in 2 consecutive 24-hour periods. If discharge criteria are not met by Day 8, subjects will remain in the study site up to Day 15.

You may qualify if…

• Males, of any race, between 18 and 55 years of age, inclusive.
• Body mass index between 18.0 and 32.0 kg/m2, inclusive.
• In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [eg, suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at screening and/or check-in as assessed by the investigator (or designee).
• Subjects will agree to use contraception as detailed in the protocol
• Able to comprehend and willing to sign an ICF and to abide by the study restrictions.
• History of a minimum of 1 bowel movement per day.

You may not qualify if…

• Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the investigator (or designee).
• History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the investigator (or designee).
• History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed). Cholecystectomy is not allowed.
• History of alcoholism or drug/chemical abuse within 2 years prior to check-in.
• Alcohol consumption of > 21 units per week. One unit of alcohol equals 12 oz (360 mL) beer, 1½ oz (45 mL) liquor, or 5 oz (150 mL) wine.
• Positive urine drug screen at screening or positive alcohol urine test result or positive urine drug screen at check-in.
• Positive hepatitis panel and/or positive human immunodeficiency virus test (Appendix 2).
• Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 5 half-lives of the drug, if known, or 30 days, whichever is longer, prior to last dose of the previous study.
• Use or intend to use any medications/products known to alter drug absorption, metabolism, cytochrome P450 1A2 and UGT1A1 inhibitors/inducers, or elimination processes, including St. John's wort, within 30 days prior to check-in, unless deemed acceptable by the investigator (or designee).
• Use or intend to use any prescription medications/products within 14 days prior to check-in, unless deemed acceptable by the investigator (or designee).
• Use or intend to use slow-release medications/products considered to still be active within 14 days prior to check-in, unless deemed acceptable by the investigator (or designee).
• Use or intend to use any nonprescription medications/products including vitamins, minerals, and phytotherapeutic/herbal/plant-derived preparations within 7 days prior to check-in, unless deemed acceptable by the investigator (or designee).
• Use of tobacco- or nicotine-containing products within 3 months prior to check-in, or positive cotinine at screening or check-in.
• Receipt of blood products within 2 months prior to check-in.
• Donation of blood from 3 months prior to screening, plasma from 2 weeks prior to screening, or platelets from 6 weeks prior to screening.
• Poor peripheral venous access.
• Have previously completed or withdrawn from this study or any other study investigating SKI-O-703, and have previously received SKI-O-703.
• Subjects with exposure to significant diagnostic or therapeutic radiation (eg, serial X-ray, computed tomography scan, barium meal) or current employment in a job requiring radiation exposure monitoring within 12 months prior to check-in.
• Subjects who have participated in more than 3 radiolabeled drug studies in the last 12 months (previous study to be at least 4 months prior to check-in to the study site where exposures are known to the investigator or 6 months prior to check-in to the study site for a radiolabeled drug study where exposures are not known to the investigator). The total 12-month exposure from this study and a maximum of 2 other previous radiolabeled studies within 4 to 12 months prior to this study will be within the Code of Federal Regulations (CFR) recommended levels considered safe, per United States Title 21 CFR 361.1.5
• Subjects who, in the opinion of the investigator (or designee), should not participate in this study.
