A Trial to Study the Absorption, Metabolism, and Excretion of [14C]-Praliciguat in Healthy Male Volunteers

Cyclerion Therapeutics8 enrolled

Overview

The primary objective is to characterize the pharmacokinetics (PK) of praliciguat and total radioactivity and to assess the elimination of total radioactivity from a single oral dose of \[14C\]-praliciguat.
