Clinical Trial Summary

The primary objective of this trial is to evaluate whether a corifollitropin alfa (Org 36286) regimen applying a single or repeated dose of corifollitropin alfa followed by a low daily dose of Human Chorion Gonadotropin (hCG) or recombinant Follicular Stimulating Hormone (recFSH) can induce monofollicular growth (one follicle ≥18 mm and no other follicle ≥15 mm at day of bolus injection of hCG) in women with WHO group II anovulatory infertility.

Description:

This trial will include two separate stages (Ia+Ib and II). Stage Ia will be open-label and uncontrolled in a small cohort of women (n=5) to explore whether the intended dosing regimen of corifollitropin alfa followed by daily low dose recFSH provide an appropriate response in eligible participants meeting all inclusion and none of the exclusion criteria. Stage Ib will be open-label and uncontrolled in a small cohort of women (n=5) to explore whether the intended dosing regimen of corifollitropin alfa followed by daily low dose hCG provide an appropriate response in eligible participants meeting all inclusion and none of the exclusion criteria. Stage II is open-label and randomized (n=40) to evaluate whether the intended dosing regimen of corifollitropin alfa followed by low dose FSH (n=20) or hCG (n=20) provide an appropriate response in eligible participants meeting all inclusion and none of the exclusion criteria.

Intervention

Drug:
• corifollitropin alfa
SC corifollitropin alfa on the 1st, 2nd or 3rd day after onset of a progestagen-induced withdrawal bleeding (Stage 1a: 15mcg, Stage Ib/II: 30 mcg).

Biological:
• recombinant Follicle Stimulating Hormone (recFSH)
Daily injections of SC recFSH (50 IU/75 IU) administered as soon as the largest follicle reaches a size =12 mm 4 days after a corifollitropin alfa injection on stimulation day 5, 9 or 13.
• human Chorion Gonadotropin (hCG)
Daily injections of SC hCG (200 IU) administered as soon as the largest follicle reaches a size =12 mm 4 days after a corifollitropin alfa injection on stimulation day 5, 9 or 13.
• hCG Bolus injection
Bolus injection of SC hCG was administered to induce final oocyte maturation if at least one follicle is =18 mm and no more than two follicles =15 mm are observed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Monofollicular Response (Monofollicular Rate)	The monofollicular rate was defined as the number of participants with monofollicular response (one follicle =18 mm and no other follicle =15 mm on the day of the bolus injection of hCG) divided by the number of the treated participants.	At day of bolus injection of hCG (up to 20 days)
Secondary	Percentage of Participants With Ovulation (Ovulation Rate)	Ovulation rate was defined as the number of participants with confirmed ovulation (=15 nmol/l serum progesterone eight days after the bolus injection of hCG) divided by the number of treated participants. Ovulation was also considered confirmed for participants who became pregnant, had an ectopic pregnancy or had a miscarriage.	8 days after bolus injection of hCG (up to 28 days)
Secondary	Percentage of Participants With Monofollicular Ovulation (Monofollicular Ovulation Rate)	Monofollicular ovulation rate was defined as the number of participants with monofollicular response (one follicle =18 mm and no other follicle =15 mm on the day of the bolus injection of hCG) and confirmed ovulation (=15 nmol/l serum progesterone eight days after the bolus injection of hCG) divided by the number of treated participants. Ovulation was also considered confirmed for participants who became pregnant, had an ectopic pregnancy or had a miscarriage.	8 days after bolus injection of hCG (up to 28 days)
Secondary	Percentage of Participants Who Cancelled Treatment (Cancellation Rate)	Treatment was considered cancelled if no bolus injection of hCG was administrated. Reasons of treatment failure included Adverse Event (AE)/ Serious Adverse Event (SAE), insufficient ovarian response on stimulation day 13 (no follicle =12 mm), insufficient ovarian response after 7 days of hCG/recFSH treatment (no follicle =18 mm), and multifollicular growth (=3 follicles =15 mm).	Up to 3 weeks after bolus injection of hCG (up to 41 days)
Secondary	Number of Participants With Pregnancy	A pregnancy test (serum or urinary hCG) was performed two to three weeks after bolus injection of hCG. In case of a positive pregnancy test vaginal and/or abdominal ultrasound scan was performed to confirm the pregnancy at 5 to 6 weeks after bolus injection of hCG and =10 weeks after bolus injection of hCG to confirm ongoing pregnancy.	At least 10 weeks after bolus injection of hCG (up to 13 weeks)
Secondary	Number of Participants With AEs of Ovarian Hyperstimulation Syndrome (OHSS)	OHSS was classified on study based on a slightly modified WHO Scientific Group (1973) classification: Grade I (mild) = characterized by excessive steroid secretion and ovarian enlargement (5-7 cm). Abdominal discomfort, including abdominal pain, is present. Grade II (moderate) = characterized by distinct ovarian cysts (ovary size 8-10 cm), accompanied by abdominal pain and tension, nausea, vomiting, diarrhea. Grade III (severe) = characterized by enlarged cystic ovaries (ovary size >10 cm), accompanied by ascites and occasionally hydrothorax. Abdominal tension and pain may be severe. Pronounced hydrothorax together with an abdominal cavity filled with cysts and fluid elevating the diaphragm may cause severe breathing difficulties. Large quantities of fluid inside the cysts and in the peritoneal and pleural cavities cause haemoconcentration and increased blood viscosity. In rare cases, the syndrome may further be complicated by the occurrence of thromboembolic phenomena.	During In-Treatment Period (up to 14 weeks after first corifollitropin injection)
