Study to Determine Absorption, Metabolism, and Excretion of [14C]-SAR439859, and to Assess Absolute Oral Bioavailability of Amcenestrant (SAR439859), in Healthy Post-menopausal Women
Study Details
Study Description
Brief Summary
Primary Objectives:
-
To assess the excretion balance after oral and IV administration of [14C]-SAR439859
-
To assess PK of total radioactivity, [14C] -SAR439859 and its metabolite (M7) after IV administration of [14C]-SAR439859 and, PK of radioactivity, SAR439859 and M7 after oral administration of SAR439859 alone or with [14C]-SAR439859
-
To assess IV clearance and absolute bioavailability of SAR439859 using microdose of [14C]-SAR439859 tracer on top of a single tablet oral dose.
-
To assess relative bioavailability of SAR439859 given as tablet or solution
Secondary objectives:
-
To collect samples in order to assess metabolic profile in plasma and excreta of SAR439859 after oral administration of [14C]-SAR439859 as solution, contribution in plasma of SAR439859 and metabolite relative to total radioactivity and identify metabolites (samples will be analyzed according to metabolic analysis plan and results will be documented in a separate report).
-
To assess safety and tolerance of SAR439859
