Outcome results

Primary

Ongoing Pregnancy Rate at the End of the Study

Time frame: 10 weeks after treatment start

Population: ITT population was analysed (i.e. all the randomised patients)

ArmMeasureValue (NUMBER)
Progesterone SCOngoing Pregnancy Rate at the End of the Study27.4 percentage of randomized patient
Progesterone Vaginal GelOngoing Pregnancy Rate at the End of the Study30.5 percentage of randomized patient
Comparison: The non -inferiority hypothesis to be tested for the primary endpoint was that the ongoing pregnancy rate (oPR) in the test group (Pe)was lower than the oPR in the control group (Pc)against the alternative one that the oPR in the test group was equal to or higher than the oPR in the control group.~H0 : Pc\>= Pe + d(-10%) H1 : Pc\< Pe + d(-10%)p-value: 0.3795% CI: [-9.9, 3.7]Chi-squared
Secondary

Delivery Rate and Live Birth Rate

Time frame: nearly 9 month after treatment start
