Comparison of Treatment Modalities in Poor Responders Undergoing IVF

January 7, 2016 updated by: Ercan Bastu
The accurate identification and efficient management of poor responders remains one of the most enigmatic challenges in assisted reproductive technology (ART). The investigators study will compare the letrozole/antagonist protocol to the hMG/antagonist protocol in women who poor responders.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
80

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

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Patients will be considered eligible if they are poor ovarian responders according to the Bologna criteria (Ferraretti et al., 2011).

  • Two out of three of the following criteria are essential in order to classify a patient as poor ovarian responder:

    • advanced maternal age (≥40 years) or any other risk factor for poor ovarian response;
    • a poor ovarian response (≤3 oocytes with a conventional stimulation protocol); or
    • an abnormal ovarian reserve test (antral follicle count, <7 follicles or anti-Mullerian hormone, <1.1 ng/ml).

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.
Active Comparator: human menopausal gonadotropin (hMG)
hMG at a dose of 300 IU/day will be initiated on the second or third day of spontaneous menstruation and continued until the day of ovulation triggering. Ovulation triggering will be performed with the administration of 10000 IU of human chorionic gonadotropin (hCG) as soon as two-three follicles of 17 mm diameter will be observed by transvaginal ultrasound.
Drug: human menopausal gonadotropin (hMG)
Active Comparator: Letrozole
Letrozole (Femara; Novartis, East Hanover, NJ) at a dose of 5 mg/day will be initiated on the second or third day of spontaneous menstruation and continued for 5 days. Again on the second or third day of spontaneous menstruation, 150 IU of hMG will be started until the day of ovulation triggering. Ovulation triggering will be performed with the administration of 10000 IU of hCG as soon as two-three follicles of 17 mm diameter will be observed by transvaginal ultrasound.
Drug: Letrozole
Other Names:
  • Femara

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Ongoing pregnancy rate
Time Frame: up to 2 weeks
The primary outcome measure will be the ongoing pregnancy rate (>12 weeks' gestation) per started cycle.
up to 2 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cancellation Rate
Time Frame: up to one month
One of the secondary outcome measures will be cancellation rate.
up to one month
Number of oocytes retrieved
Time Frame: up to one month

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
