Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hormone preparations like REKOVELLE and GONAL-F are used to make the body produce multiple egg sacs, allowing more eggs to be collected from women undergoing infertility treatment.

The main purpose of this trial is to see how many eggs are produced with a starting dose of 15 µg REKOVELLE compared to a starting dose of 225 IU GONAL-F. This research is intended to provide more knowledge about REKOVELLE, including the doses given in the trial.

REKOVELLE (Follitropin Delta)

Group Type EXPERIMENTAL

REKOVELLE (Follitropin Delta)

Intervention Type DRUG

REKOVELLE administered as single daily subcutaneous injections in the abdomen. The starting dose of REKOVELLE was 15 μg fixed for the first four stimulation days. Dose adjustments could be implemented on the day of starting the gonadotropin-releasing hormone (GnRH) antagonist (stimulation day 5 or day 6) or later, could occur no more frequently than every second day. At each dose adjustment, the daily REKOVELLE dose could be increased or decreased by 5 μg based on the participant's response. The minimum REKOVELLE dose was 5 μg and the maximum REKOVELLE was 20 μg. Participants could be treated for a maximum of 20 days.

GONAL-F (Follitropin Alfa)

Group Type ACTIVE_COMPARATOR

GONAL-F (Follitropin Alfa)

Intervention Type OTHER

GONAL-F administered as single daily subcutaneous injections in the abdomen. The starting dose of GONAL-F was 225 IU fixed for the first four stimulation days. Dose adjustments could be implemented on the day of starting the GnRH antagonist (stimulation day 5 or day 6) or later, could occur no more frequently than every second day. At each dose adjustment, the daily GONAL-F dose could be adjusted by 75 IU based on the participant's response. The minimum GONAL-F dose was 75 IU and the maximum GONAL-F dose was 300 IU. Participants could be treated for a maximum of 20 days.

Intervention Type DRUG

GONAL-F (Follitropin Alfa)

GONAL-F administered as single daily subcutaneous injections in the abdomen. The starting dose of GONAL-F was 225 IU fixed for the first four stimulation days. Dose adjustments could be implemented on the day of starting the GnRH antagonist (stimulation day 5 or day 6) or later, could occur no more frequently than every second day. At each dose adjustment, the daily GONAL-F dose could be adjusted by 75 IU based on the participant's response. The minimum GONAL-F dose was 75 IU and the maximum GONAL-F dose was 300 IU. Participants could be treated for a maximum of 20 days.
