Corifollitropin Alfa Versus Daily rFSH in the Controlled Ovarian Stimulation of Poor Responders (MANCOR)

January 15, 2016 updated by: IVI Sevilla

Comparative Study Between the Use of Corifollitropin Alfa and Daily Recombinant FSH in the Controlled Ovarian Stimulation of Poor Responders

A randomised, crossover, multicentre, national, clinical trial comparing the efficacy of corifollitropin alfa versus daily recombinant FSH and HMG in the controlled ovarian stimulation of women with a poor ovarian response undergoing IVF treatments. The main objective of this study is comparing the number of oocytes obtained after the follicle puncture when using each of these two stimulation protocols. Only poor responders according to the Bologna criteria will be recruited for this trial. All participants will undergo two stimulation cycles to obtain and accumulate oocytes by vitrification. One of the cycles will be done with the corifollitropin alfa protocol and the other with daily rFSH and HMG, the order of application of these protocols will be randomised (crossover clinical trial) in each patient.

Study Overview

Status

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.
Interventional

Enrollment (Actual)

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.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Advanced maternal age (≥40 years)
  • A previous poor ovarian response (≤3 oocytes with a conventional stimulation protocol)
  • An abnormal ovarian reserve test (i.e. antral follicle count <5-7 follicles or anti-mullerian hormone level <0.5-1.1 ng/ml)

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
Number of mature oocytes (metaphase II)
Time Frame: 1 year
Number of mature oocytes (metaphase II) obtained after the follicle puncture
1 year

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
Total number of oocytes
Time Frame: 1 year
Total number of oocytes obtained after the follicle puncture
1 year
Symptoms associated with the ovarian stimulation protocol
Time Frame: 1 year
Patients will evaluate their symptoms using a questionnaire. They will score the intensity (from 1 to 10) of each of the following symptoms: pelvic pain, headache, mood swings, nausea, tiredness, breast pain.
1 year
Patient perception of the stimulation treatment
Time Frame: 1 year
Patients will evaluate how they have perceived the stimulation treatment using a questionnaire. They will score their comfort (from 1 to 10) with the following aspects of the treatment: treatment administration, number of injections and treatment length.
