A Single-Radiolabeled Dose Mass Balance Study To Investigate The Absorption, Metabolism, And Excretion Of [14C] Palbociclib (PD-0332991) In Healthy Male Volunteers

Completed · Phase 1

Conditions studied: Healthy

In brief

This will be an open-label, single-center study to evaluate the mass-balance and pharmacokinetics of PD-0332991 in approximately 6 healthy male subjects receiving a single oral 125 mg dose of PD-0332991 containing approximately 100 microcuries of \[14C\]-PD-0332991. Subjects will be checked in to the research unit from approximately 12 hours prior to dosing and remain in house until greater than 90% of the administered radioactivity is collected from bodily excreta or until less than 1% of the administered radioactivity is recovered from excreta on consecutive days. This study will investigate the extent of involvement of the renal and hepatic systems in the elimination of PD-0332991 and will seek to identify the compound's major metabolites.
