Details and patient eligibility

About

The objective of follow-up study P05713 is to evaluate whether corifollitropin alfa (Org 36286) treatment for the induction of monofollicular growth in women who underwent ovulation induction (OI) in base study P05693 (NCT00697255) is safe for pregnant participants and their offspring.

Full description

Base study P05693 (NCT00697255) was planned to include two separate stages (Ia+Ib and II).

Stage Ia was 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 recombinant Follicle Stimulating Hormone (recFSH) would provide an appropriate response in eligible participants meeting all inclusion and none of the exclusion criteria.

Stage Ib was open-label and uncontrolled in a small cohort of women (n=3) to explore whether the intended dosing regimen of corifollitropin alfa followed by daily low dose Human Chorion Gonadotropin (hCG) would provide an appropriate response in eligible participants meeting all inclusion and none of the exclusion criteria.

Stage II was planned to be open-label and randomized (n=40) to evaluate whether the intended dosing regimen of corifollitropin alfa followed by low dose recFSH (n=20) or hCG (n=20) would provide an appropriate response in eligible participants meeting all inclusion and none of the exclusion criteria.

P05713 is a follow-up (FU) study to prospectively monitor pregnancy, delivery, and neonatal outcome of women who became ongoing pregnant during base study P05693 (NCT00697255). For this trial, no study specific assessments will be required and no treatment will be administered, but information as obtained in standard practice will be used. Enrollment will begin when the first ongoing pregnancy resulting from the base study has been established (ultrasound ≥ 10 weeks after bolus injection of hCG).

Enrollment: 1 patient

Trial design

1 participants in 2 patient groups

corifollitropin alfa + recFSH Mothers

Description:

Eligible participants in Stage 1a of base study P05693 (NCT00697255) were administered injection(s) with subcutaneous (SC) corifollitropin alfa (15mcg) and daily SC injections with recFSH (50 IU) when the largest follicle reached a size of ≥12 mm. A bolus injection of hCG (5000 IU) was then administered if at least one follicle was ≥18 mm and in total no more than two follicles ≥15 mm were observed. Eligible mothers in this group with an ongoing pregnancy established in the base study (confirmed at ≥10 weeks after hCG bolus injection) were then to be followed for safety and efficacy on the current follow-up (FU) study (P05713) according to standard practice (no treatment administered).

Treatment:

Biological: recombinant Follicle Stimulating Hormone (recFSH)

Drug: corifollitropin alfa

Biological: hCG Bolus injection

corifollitropin alfa + hCG Mothers

Description:

Eligible participants in Stage 1b of base study P05693 (NCT00697255) were administered injection(s) with SC corifollitropin alfa (30 mcg) and daily SC injections with hCG (200 IU) when the largest follicle reached a size of ≥12 mm. A bolus injection of hCG (5000 IU) was then administered if at least one follicle was ≥18 mm and in total no more than two follicles ≥15 mm were observed. Eligible mothers in this group with an ongoing pregnancy established in the base study (confirmed at ≥10 weeks after hCG bolus injection) were then followed for safety and efficacy on the current FU study (P05713) according to standard practice (no treatment administered).
