NCT05263388

Brief Summary

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.

Study Arms (2)

REKOVELLE (Follitropin Delta)

EXPERIMENTAL
Drug: REKOVELLE (Follitropin Delta)

GONAL-F (Follitropin Alfa)

ACTIVE COMPARATOR
Other: GONAL-F (Follitropin Alfa)

Interventions

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.

REKOVELLE (Follitropin Delta)

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.

GONAL-F (Follitropin Alfa)

Eligibility Criteria

Sexfemale(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Infertile women aged 18-40 years
