Single Dose Study With Unlabeled Dose and 14C-labeled Microdose of PF-06700841 in Healthy Male Subjects

Registration Number
NCT03770039
Lead Sponsor
Pfizer
Brief Summary

An open-label, fixed sequence, 2-period including a single oral dose 60 mg PF-06700841 with 14C-labeled microtracer in 1st period, and a single oral dose of 60 mg unlabeled PF-06700841 followed by intravenous administration of 14C-labeled microdose of PF-06700841 1 hour after oral dose in period 2 to characterize the absorption, disposition, metabolism and excretion of PF-06700841 and evaluate the absolute bioavailability and fraction absorbed in the GI tract
