A Trial to Study the Absorption, Metabolism, and Excretion of [14C]-Olinciguat in Healthy Male Volunteers
- Conditions
- Healthy Volunteers
- Interventions
- Drug: [14C]-olinciguat
- Registration Number
- NCT03795519
- Lead Sponsor
- Cyclerion Therapeutics
- Brief Summary
The primary objective is to characterize the pharmacokinetics (PK) of olinciguat and total radioactivity and to assess the elimination of total radioactivity from a single oral dose of \[14C\]-olinciguat.
- Detailed Description
OLI-103 is a Phase 1 open-label, nonrandomized, single-dose study in up to 8 subjects that will be conducted at a single center in the US. Safety assessments will be performed throughout the clinic period and multiple PK samples will be collected. Subjects will be confined to the clinical research center for at least 8 days.
The purpose of the study is to determine the absorption, metabolism, and excretion of \[14C\]-olinciguat and to characterize and determine, where possible, the metabolites present in plasma, urine, and feces after a single oral dose. The study will help identify and characterize olinciguat metabolites, evaluate the likelihood of effects of liver or kidney impairment on the disposition of olinciguat, and assess the likelihood of drug-drug interactions with olinciguat.
