Evaluate The Safety, Tolerability and Pharmacokinetics Of Multiple Ascending Oral Doses Of WCK 4873 In Healthy Adult Volunteers

Double-Blind, Randomized, Placebo-Controlled Study To Evaluate The Safety, Tolerability And Pharmacokinetics Of Multiple Ascending Oral Doses Of WCK 4873 In Healthy Adult Volunteers

This is a Phase 1, randomized, double-blind, single center, placebo-controlled, sequential cohort study in a maximum of 3 cohorts of 10 healthy male and/or female subjects each. Subjects in Cohorts 1, 2 and 3 will receive ascending multiple oral doses of WCK 4873 or matching placebo once daily on Days 1 to 7. Dosing will be conducted under fed conditions on each dosing day. The dose levels to be administered will be based on the safety, tolerability and PK results of the single dose and food effect study (W 4873 01 study; PRA-code WOE384EC-123841).
