NCT00298025	A Study to Compare the Safety and Efficacy of Cetrotide® 3 Milligram (mg) Versus Antagon™ in Women Undergoing Ovarian Stimulation	Completed	EMD Serono	Phase 4	2003-09-01	To demonstrate the comparative safety and efficacy of Cetrotide® 3 milligram (mg) and Antagon™ in the inhibition of a premature luteinizing hormone (LH) surge in women undergoing ovarian stimulation with recombinant human follicle stimulating hormone/human menopausal gonadotropin (r-hFSH/hMG) prior to assisted reproductive technology (ART) and utilizing oral contraceptives pill (OCP) for cycle programming.
NCT00439829	Synchronization of Follicle Wave Emergence and Ovarian Stimulation	Completed	Royal University Hospital Foundation	Phase 4	2007-02-01	The objective of the study is to elucidate the effect of synchronizing initiation of ovarian stimulation treatment with follicular wave emergence in poor responder patients undergoing IVF/ICSI and ET. We hypothesize that initiating treatment on day 1 versus day 4 of the cycle will increase the number of follicles recruited and oocytes retrieved.
NCT00439829	Synchronization of Follicle Wave Emergence and Ovarian Stimulation	Completed	University of Saskatchewan	Phase 4	2007-02-01	The objective of the study is to elucidate the effect of synchronizing initiation of ovarian stimulation treatment with follicular wave emergence in poor responder patients undergoing IVF/ICSI and ET. We hypothesize that initiating treatment on day 1 versus day 4 of the cycle will increase the number of follicles recruited and oocytes retrieved.
NCT00460642	GnRH Antagonist to Prepare Recipients for Embryo Transfer	Completed	Institute for Human Reproduction (IHR)	N/A	2007-01-01	26% of all ART cycles performed in the USA in 2003 (CDC data) are frozen embryo transfers (FET) and transfer of embryos resulting from egg donation (ED) to recipients. The typical protocol used to prepare a recipient for ET involves GnRH agonist (Lupron, Tap Pharmaceuticals) to down regulate the patient. A GnRH antagonist, such as Cetrotide (EMD Serono), is comparable to GnRH agonist and FDA approved to prevent spontaneous ovulation with ART treatment, and its usage decreases significantly the number of injections that the patient receives with treatment. The working hypothesis for this study is that the GnRH antagonist (Cetrotide) can be used instead of an agonist to achieve effective down regulation in FET and ED cycles. Presumably, patients will prefer Cetrotide over Lupron because of the markedly fewer injections required.
NCT00507780	Effect of Cetrorelex Acetate on Ovarian Function in Women Undergoing Chemotherapy	Withdrawn	Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)	Phase 4	2007-07-01	This study will examine whether the drug cetrorelex acetate (Cetrotide[Registed Trademark]) can protect ovarian function in women undergoing chemotherapy. Some cancer treatments are known to cause a change in women's periods or to cause menstruation to stop completely, so that they cannot become pregnant. Cetrorelex acetate has been used for many years to lower hormone levels and stop periods in patients undergoing in vitro fertilization treatments. This study will see if making the ovaries inactive may protect them from being affected by certain cancer drugs, and thus preserve fertility. Women up to age 21who have begun menstruating, who have their uterus and at least one functioning ovary, and who are undergoing chemotherapy with cyclophosphamide, busulfan, nitrogen mustard or L-phenalanin mustard may be eligible for this study. Participants undergo the following procedures during this 24-month study: Baseline evaluation - Medical history, physical examination and blood and urine tests - Questionnaire about quality of life, menstrual periods, vaginal bleeding and desire for future fertility - 3D ultrasound of abdomen - DEXA scan to evaluate bone density Assignment to treatment with: - Lo ovral (contraceptive pill to prevent pregnancy and control menstrual periods) alone, or - Lo ovral and the study drug cetrorelex acetate, given as an injection under the skin once a day for six menstrual cycles Evaluations - Transvaginal 3D ultrasound to monitor changes in the ovary - after 6 months of cetrorelex acetate injections - DEXA scan - after 6 months of cetrorelex acetate injections - Blood tests for safety monitoring, pregnancy testing, endocrine tests and research uses - every 3 months during first year, every 6 months during second year - Questionnaire to monitor changes and quality of life - every 3 months during first year, every 6 months during second year.
NCT00633347	Use of Antagonist Versus Agonist GnRH in Oocyte Recipient Endometrium Preparation	Completed	Instituto Valenciano de Infertilidad, IVI VALENCIA	Phase 4	2007-01-01	Oocyte donation is a well established procedure in assisted reproduction treatments (ART). It is demonstrated that the use of hormonal substitution therapy, for the synchronization of the cycles between the recipients and the donors, provides good results, similar to the ones obtained with the natural cycle. In the patients - recipients with preserved ovarian function, the recipient's natural cycle is annulled, thus preventing the spontaneous Luteinizing Hormone surge. Simultaneously and while waiting for the suitable donor, her endometrium is prepared. When the donation occurs and fertilization with the husband sperm takes place, her cycle is stimulated again in order to synchronize her window of implantation with the donor's ovulation. Two different medications are commonly used to inhibit spontaneous ovulation: either GnRHa agonist or GnRH antagonists. The present study consists of the comparison between the single dose GnRH agonist (Decapeptyl 3,75 IM) and the 7 day dosage of GnRH antagonist (Cetrotide 0,25 mg). The administration of GnRHa is used fundamentally as a long liberation formulation, administered in a single intramuscular injection (IM), which is more practical in terms of use. Nevertheless, the unnecessary persistence and the potentially unfavorable action of GnRHa during the luteal phase and early gestation have questioned its use. The recovery of the Hypophysarian function begins only 8 weeks after the single injection of long liberation of triptorelina 3.75 mg. The GnRH antagonist (Cetrotide 0,25 mg) makes the hypofisary inhibition shorter than with the analogues and can prepare similar endometrium characteristics as a natural cycle. The recipients will be assigned randomly to a group of treatment or another.
NCT00746031	Novel MRI Strategies as a Non-invasive Biomarker in Women With Uterine Fibroids	Completed	NHS Lothian	Phase 4	2008-12-01	Fibroids are present in up to 80% of women of reproductive age. Associated heavy menstrual bleeding is often an indication for surgery. At present there are no long-term medical treatments for fibroids. There is an unmet need for a pharmacologic agent able to reduce excessive bleeding and other symptoms associated with increased uterine volume, which could prevent or significantly delay surgery without causing significant unwanted hypoestrogenic side effects and allow preservation of fertility. The purpose of this study is to investigate and validate novel MR imaging as a non-invasive biomarker for monitoring responses to medical interventions aimed at reduction of excessive menstrual bleeding and decrease in uterine/ fibroid volume. MR imaging is non-invasive, does not involve ionizing radiation and new techniques have the potential to resolve tissue detail to near cellular level. The investigators are aiming to establish the feasibility and reproducibility of novel MR imaging techniques in the evaluation of treatment response in women with fibroids and to provide mechanistic information on whether the reduction in blood flow of uterine/fibroid vasculature in the shrinkage of fibroids is dependent upon subjects being hypoestrogenic.
