Efficacy of Corifollitropin Alfa in Obese Women in Terms of Clinical and Molecular Parameters of IVF Success

May 2, 2018 updated by: Tanja Burnik Papler, University Medical Centre Ljubljana
The aim of the present study is to determine, whether clinical efficacy of 150 mcg of Corifollitropin alfa is the same in normal weighing and obese women. Furthermore, investigators want to determine whether oocytes retrieved from normal weighing and obese women, after COH using 150 mcg of Corifollitropin alfa, are of same quality on the molecular level.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The dosage of Corifollitropin alfa used for controlled ovarian hyperstimulation (COH) is adjusted according to the patient's body weight. Meaning, in women with a body weight ≤ 60 kg, a single dose of 100 mcg of Corifollitropin alfa is administered for COH and in women with a body weight > 60 kg, a single dose of 150 micrograms of Corifollitropin alfa is administered for COH. These two protocols are comparable in safety and efficacy of follicular stimulation.

On the other hand, knowledge about the clinical efficacy of 150 mcg of Corifollitropin alfa in obese women (BMI>30 kg/m2) is lacking.

Cumulus cells (CC) surround the oocyte and bi-directional communication between oocyte and CC is necessary for the development of mature and quality oocytes. It has been proposed, that analysis of genes, expressed in CC, can serve as an objective indicator of the oocyte's maturity and developmental potential. Expression of genes in CC as hyaluronan synthase 2 (HAS2), follicle-stimulating hormone receptor (FSHR), versican (VCAN), progesterone receptor (PR), vascular endothelial growth factor C (VEGFC), serine protease inhibitor E2 (SERPINE2), glutathione peroxidase (GPX3), pentraxin 3(PTX3) was reported to correlate with oocyte maturity and developmental potential.

The effect of Corifollitropin alfa on expression of these genes however, is unknown.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Elonva 150 mcg
Elonva 150 mcg intramuscular daily obese
Drug: Elonva

20 obese women will be the study group and 20 normal weighing women will be the control group. Both groups will receive 150 mcg of Elonva for controlled ovarian hyperstimulation (COH). Gonadotropin-releasing hormone (GnRH) antagonist will be used to prevent premature luteinizing hormone (LH) surge. Additional daily doses of 200 IU of recombinant follicle stimulating hormone (rFSH) will be used if necessary. Human chorionic gonadotropin (hCG) will be used for oocyte maturation. 2 mature follicles will be aspirated separately in each patient. Cumulus cell (CC) samples will be collected and stored on -80 oC for subsequent analysis. Clinical and molecular parameters of IVF success will be assessed and compared between the groups.

The exclusion criteria will be: polycystic ovary syndrome, severely abnormal sperm parameters, and age > 38 years.
