Corifollitropin Alpha and Ovarian Response

June 1, 2020 updated by: Hospital de Clinicas de Porto Alegre

Ovarian Response to Controlled Ovarian Stimulation Measured Through the Follicular Output Rate (FORT)

Objective: To study whether an administration of corifollitropin alpha modifies the follicular cohort, measured by Follicular Output Rate (FORT), compared to human menopausal gonadotropin (HMG), in infertile patients undergoing in vitro fertilisation (IVF).

M/M: 306 infertile patients undergoing in vitro fertilisation (IVF). Ovarian stimulation protocol will be performed with a single dose of 100 μg (<60kg) or 150 μg (≥60kg) corifollitropin alpha in group 1 (n=147), and 150-300 IU/day human menopausal gonadotropin (HMG) according to age, antimullerian hormone (AMH) level and antral follicle count (AFC) in group 2 (n=150).

Moreover, FORT will be calculated as the ratio of pre-ovulatory follicle (16-22 mm in diameter) count on day of HCG×100/small antral follicle (3-8 mm) count at baseline.

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

Patients will be allocated for convenience into two groups: those who would receive corifollitropin alpha (Group 1) or HMG (Group 2).

Ovarian stimulation protocol will be performed with a single dose of 100 μg (<60 kg) or 150 μg (≥60 kg) of corifollitropin alpha (Elonva, Schering-Plough, Brazil) in group 1, which could be followed by daily administration of HMG beginning on day 8 if necessary; in group 2 150-300 IU/day HMG (menotropin, Menopur, Ferring, Brazil) will be administered, starting on cycle day 3, according to age, AMH level and AFC, plus gonadotropin-releasing hormone antagonist co-treatment (Ganirelix 25 mcg/day, Orgalutran, Schering-Plough, Brazil) in a flexible protocol (at least 1 follicle >14 mm or 3 or more follicles >12 mm). Doses will be adjusted as needed by the patient according to the ultrasound, which is performed with a 6 MHz multifrequency transvaginal probe (Toshiba, Japan). The criterion for HCG administration (5.000 IU Choriomon, Biopharma, Brazil) will be at least three follicles greater than 17 mm, and then, 36 hours later, transvaginal oocyte retrieval was performed. After 3 or 5 days, one or two good-quality embryos will be transferred. It will be performed intracytoplasmic sperm injection (ICSI) instead of conventional IVF when major male factor is presented.

Primary outcome measure is FORT. Secondary outcome measures include number of oocytes retrieved, MII, duration of stimulation, number of embryos, embryo quality and clinical pregnancy rate. Adverse events, such as ovarian hyperstimulation syndrome (OHSS) or drug-related complications are also monitored.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 42 years (ADULT)

Accepts Healthy Volunteers
