Primary

MeasureTime frame
Secondary Objective: • To explore the safety of Mifepristone tablet 150 mg • To explore the efficacy and safety of the dose of Mifepristone 75 mg in Part II of the study (if positive efficacy and safety outcomes are achieved in Part I) • To explore efficacy and safety of Mifepristone 300 mg in Part II of the study (if efficacy is not proven with a favourable safety profile in Part I) ;Primary end point(s): Gain in Bishop score 48 hours from baseline ;Timepoint(s) of evaluation of this end point: 48 hours after the drug administration;Main Objective: The primary objective of the study is to compare the efficacy of Mifepristone tablet 150 mg with placebo in cervix ripening in full-term pregnancy 48 hours after baseline
