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
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.
