About this study
Official title: Prospective, Randomized Open Trial to Evaluate the Efficacy of an Ovarian Stimulation Protocol Based on FSH Receptor Genotype
Available data from in vitro studies and clinical trials indicate that genetic factors play a significant role in the success of controlled ovarian stimulation (COS) prior to in vitro fertilization - embryo trandfer (IVF-ET). Women with the FSHR Ser680Asn Ser/Ser genotype make up between 13% and 26% of women undergoing IVF-ET and are characterised by higher basal FSH serum concentrations, the need for a higher amount of FSH for COS, and a higher risk of poor response to COS and cycle cancellation.
The investigators therefore intend to perform a study to investigate whether a dose-intensified COS protocol based on FSHR genotype status in women with the FSHR Ser680Asn Ser/Ser genotype is more effective than routine management in terms of

Eligible women will be randomized to a stimulation protocol characterised by a longer duration and increased dosage of FSH stimulation (group A) or a standard stimulation protocol (group B).
Read the detailed description
Women in group A will undergo controlled ovarian stimulation according to the following protocol:
Pituitary down-regulation will be achieved using buserelin (Suprefact®, Hoechst, Frankfurt, Germany) at a fixed daily dose of 200 mg s.c., according to a long agonist protocol, starting on day 2 of the normal menstrual cycle. Treatment with r-hFSH (Gonal-F®, Serono Austria GmbH, Vienna, Austria) will be started in women with serum E2 concentrations <200 pmol/l and no follicles >15 mm in diameter or ovarian cysts on ultrasonographic examination. The initial r-hFSH dose will be 250 IU s.c. daily for 5 days, after which the dose will be increased to a maximum of 450 IU per day using a step-up protocol with steps of 50 IU/day.
Once the leading follicle has reached a diameter of 14 mm, patients will receive r-hLH (lutropin alfa; Luveris®, Serono Austria GmbH, Vienna, Austria) at a dose of 75 IU s.c. for a maximum of 10 days. A dose of 75 IU LH per day was chosen based on findings from a controlled, prospective, dose-finding study in gonadotrophin-deficient women (WHO I classification) (7). Ovulation will be induced by administration of HCG (Profasi®, Serono Austria GmbH, Vienna, Austria), 10 000 IU i.m. or s.c., when at least two follicles have reached a diameter of >17 mm.
Oocyte retrieval will be performed by ultrasound-guided follicular aspiration techniques 34-38 h after administration of HCG. IVF will be performed according to standard practices at our institution. A maximum of three embryos will be transferred 48 h after oocyte retrieval (ESHRE Committee on Good Clinical and Laboratory Practice, 1995 ). Patients will receive micronized progesterone, 600 mg/day, by vaginal administration for at least the first 3 weeks of pregnancy, beginning on the day of embryo transfer.
Women in group B will undergo ovarian hyperstimulation according to the following protocol:
No pituitary down-regulation will be performed. Treatment with r-hFSH (Gonal-F®, Serono Austria GmbH, Vienna, Austria) will be started in women with serum E2 concentrations <200 pmol/l and no follicles >15 mm in diameter or ovarian cysts on ultrasonographic examination. The r-hFSH dose will be 150 IU s.c. daily for 11 consecutive days.
Once the leading follicle has reached a diameter of 14 mm, patients will receive r-hLH (lutropin alfa; Luveris®, Serono Austria GmbH, Vienna, Austria) at a dose of 75 IU s.c. for a maximum of 10 days. A dose of 75 IU LH per day was chosen based on findings from a controlled, prospective, dose-finding study in gonadotrophin-deficient women (WHO I classification) (European Recombinant Human LH Study Group, 1998 ). Ovulation will be induced by administration of HCG (Profasi®, Serono Austria GmbH, Vienna, Austria), 10 000 IU i.m. or s.c., when at least two follicles have reached a diameter of >17 mm.
Oocyte retrieval will be performed by ultrasound-guided follicular aspiration techniques 34-38 h after administration of HCG. IVF will be performed according to standard practices at our institution. A maximum of three embryos will be transferred 48 h after oocyte retrieval (ESHRE Committee on Good Clinical and Laboratory Practice, 1995 ).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing follicle stimulating hormone in people with Sterility, run by Medical University of Vienna at 1 site in Austria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: paused, as of the sponsor's last update on 5 May 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
clinical pregnancy rate (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 May 2015.
