Low-dose Gonal-f® in Ovulation Induction — LoGo  

Infertility Clinical Trial

Official title: A Multi-Centre, Two-Arm, Interventional, Phase IV Study to Evaluate Tailoring of Recombinant FSH Treatment in Subjects With Chronic Anovulation Using the Gonal-f® Prefilled Pen in Women Undergoing Ovulation Induction

Status Completed

Clinical Trial 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.

Clinical Trial 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). ;
