March 31, 2020 updated by: Drugs for Neglected Diseases
A Phase 1, Blinded, Randomized, Placebo Controlled, Parallel-Group, Single-Dose, Dose-Escalation Study to Investigate Safety, Tolerability, and Pharmacokinetics of Emodepside (BAY 44-4400) After Oral Dosing in Healthy Male Subjects
This study will investigate the safety, tolerability, and pharmacokinetics of single ascending doses of emodepside (BAY 44-4400) in healthy male volunteers.
This study will also conduct an exploratory investigation of the relative bioavailability of emodepside administered as tablets and determine the effect of food on the pharmacokinetics.
