Brief summary

This trial investigates the effects of FE 999049 compared to placebo.

Interventions

FE 999049 was administered as single daily subcutaneous injections in the abdomen at a starting dose of 15 μg daily that was fixed for the first four stimulation days. Based on ovarian response, the dose could be adjusted by 3 μg, with dose increases implemented not more frequently than once every 2 days and dose decreases implemented per investigator's judgement. The minimum daily dose was 6 μg, and the maximum daily dose was 24 μg. Participants could be treated for a maximum of 20 days. Coasting, use of dopamine agonist or any other drug to prevent early ovarian hyperstimulation syndrome (OHSS) with the exception of gonadotropin-releasing hormone (GnRH) agonist for triggering of final follicular maturation, was not allowed

DRUGPlacebo

Placebo was administered as single daily subcutaneous injection dialed to the same value (dose) as FE 999049. Participants could be treated for a maximum of 20 days. Coasting, use of dopamine agonist or any other drug to prevent early OHSS with the exception of GnRH agonist for triggering of final follicular maturation, was not allowed.

Recruitment details

The trial was performed in 24 investigational sites in 18 states of the United States between Oct 2018 to Dec 2020.

Pre-assignment details

In total, 666 participants were screened of which 588 participants were randomized. Of the randomized participants, 587 participants were exposed to the investigational medicinal product (IMP): 533 to FE 999049 (Follitropin Delta) and 54 to Placebo. One participant was randomization failure and did not receive the IMP.

Participants by arm

ArmCount
FE 999049 (Follitropin Delta)
FE 999049 was administered as single daily subcutaneous injections in the abdomen at a starting dose of 15 μg daily that was fixed for the first four stimulation days. Based on ovarian response, the dose could be adjusted by 3 μg, with dose increases implemented not more frequently than once every 2 days and dose decreases implemented per investigator's judgement. The minimum daily dose was 6 μg, and the maximum daily dose was 24 μg. Participants could be treated for a maximum of 20 days. Coasting, use of dopamine agonist or any other drug to prevent early OHSS with the exception of GnRH agonist for triggering of final follicular maturation, was not allowed.
533
Placebo
Placebo was administered as single daily subcutaneous injection dialed to the same value (dose) as FE 999049. Participants could be treated for a maximum of 20 days. Coasting, use of dopamine agonist or any other drug to prevent early OHSS with the exception of GnRH agonist for triggering of final follicular maturation, was not allowed.

Primary

Cumulative Ongoing Pregnancy Rate After the Fresh Cycle and Cryopreserved Cycles Initiated Within 12 Months From the Start of Controlled Ovarian Stimulation (COS)

Defined as at least one intrauterine viable fetus 8-9 weeks after transfer. Data in this endpoint are presented for the fresh cycle and the cryopreserved cycles.

Time frame: 8-9 weeks after transfer (up to approximately 16 months after start of stimulation)

Population: The mITT analysis set comprised all randomized and exposed participants. Participants were analyzed according to planned treatment.
