Effect of LH Supplementation on the Endometrial Gene Expression Profile in Poor Ovarian Responders

February 26, 2024 updated by: Liese Boudry, CRG UZ Brussel

Endometrial Gene Expression Profiles During Ovarian Stimulation With Recombinant FSH With or Without the Addition of Recombinant LH in Genuine Poor Responders

This is a prospective randomized open-label cross-over study. Poor responder patients will undergo two ovarian stimulation cycles. One with recombinant follicle stimulation hormone (FSH), and an other stimulation with recombinant FSH and recombinant luteinizing hormone (LH). In both groups, a freeze-all strategy will be applied and an endometrial biopsy will be taken 7 days after final oocyte maturation trigger. Endometrial gene expression analysis will be performed on both biopsies. After completion of both treatment cycles, a frozen embryo transfer of a single embryo will be performed.

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

This is a prospective randomized open-label cross-over study, in which patients will be randomized to either start in the control group or in the study group. Participants will undergo both treatments with an interval of minimum 1 and maximum 6 months. In both treatment arms, ovarian stimulation will be started at day 2/3 of the menstrual cycle. In the control group, 225 IU of recombinant FSH will be administered in a fixed antagonist protocol. In the study group, 225 IU of recombinant FSH plus 112,5 IU of recombinant LH will be administered. Cycle monitoring will be performed through serum estradiol (E2), progesterone (P), and luteinizing hormone (LH) assessments, combined with serial ultrasound examinations. Both groups will undergo dual triggering with gonadotropin releasing hormone agonist (GnRHa) 0,2ml and human chorionic gonadotrophin (hCG) 6500IU if one or more follicles of ≥ 17 mm are observed. The oocyte retrieval (OR) will be performed between 34 and 36 hours after final oocyte maturation trigger. At each OR, follicles will be individually meas-ured, aspirated and searched for the presence of cumulus oocyte complexes (COC). Metaphase II (MII) oocytes will then be injected to standard intra-cytoplasmatic sperm injection (ICSI) procedures. In both groups, a freeze-all strategy will be applied. An endometrial biopsy (Pipelle de Cornier ®) will be taken 7 days after final oocyte maturation trigger. After completion of both treatment cycles, a frozen embryo transfer of a single embryo will be performed.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.
