Keywords: Monofollicular Development Gonal-f® Recombinant Follicle Stimulating Hormone Ovarian hyperstimulation syndrome (OHSS)
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 24
Healthy volunteers: no

Brief summary:
This is a prospective, multicenter, open-label, comparative and parallel-group study of ovulation induction evaluating tailoring of Recombinant follicle stimulating hormone (FSH) treatment using the Gonal-f® prefilled pen in World Health Organization (WHO) Type 2 anovulatory subjects who have previously failed to conceive with clomifene treatment.

Detailed description:
Subjects will enter a screening period of up to one month before being randomized at the Baseline Visit, which will occur on Day 1 of the subject's menstrual cycle. Each subject will then receive up to 4 weeks treatment with Gonal-f®. If adequate follicular development (assessed by transvaginal ultrasound) is achieved, the subject will proceed to administration of human chorionic gonadotropin (hCG) within 24-48hrs of last Gonal-f® injection (or according to standard site practice).

Following administration of hCG, subjects will attempt to become pregnant via intercourse or intrauterine insemination. The method of conception will be determined by the subject's requirements and standard practice at the clinic site.

All subjects will be followed up appropriately until confirmation of biochemical pregnancy (hCG + minimum 14 days) and clinical pregnancy (hCG + minimum 42 days, for subjects with positive biochemical pregnancy test).

Arms:
arm 1: Gonal-f was administered subcutaneously daily at a starting dose of 50 International unit (IU) for Week 1, then dose was gradually increased by 12.5 IU for two weeks, with a final increase of 25 IU, up to maximum dose of 100 IU, until Week 4 for subjects with minimal response. After adequate follicular development was achieved, the subject was administration human chorionic gonadotropin (hCG) within 24-48 hours of last Gonal-f injection as per investigator discretion. arm 2: Gonal-f was administered subcutaneously daily at a starting dose of 50 International Units (IU) for Week 1, then dose was gradually increased by 12.5 IU for two weeks, up to maximum dose of 125 IU, until Week 4 for subjects with minimal response. After adequate follicular development was achieved, the subject was administration human chorionic gonadotropin (hCG) within 24-48 hours of last Gonal-f injection as per investigator discretion.
