RESCUE PROTOCOL AND FRESH EMBRYO TRANSFER

February 8, 2019 updated by: Istituto Clinico Humanitas

RESCUE PROTOCOL AND FRESH EMBRYO TRANSFER AFTER TRIGGER WITH ANALOGS OF GNRH: THE HUMANITAS PROTOCOL

Ovarian Hyperstimulation Syndrome (OHSS) is one of the most dangerous complications of Assisted Reproductive Technologies (ART) cycles. The use in clinical practice of the GnRH antagonist has made it possible to perform the trigger with GnRH analogues reducing the risk of OHSS. The trigger with analogue increases the Abortion Rate (AR) and reduces the Ongoing Pregnancy Rate (OPR), because the luteal phase in these cycles is particularly deficient. To reduce this occurrence several studies have focused on the importance of support of the luteal phase. The aims of study is to evaluate OPR and AR in patients at intermediate risk of OHSS (<18 recovered oocytes) which performed GnRH trigger and rescue protocol.

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.
Observational

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.

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 38 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

In HR patients (AMH> 3.5 ng / ml, AFC> 15 follicles and if more than 18 follicles with diam. 12mm to induction) the trigger was obtained with triptorelin 0.2 mg / sc. In patients considered to be at intermediate risk of OHSS a rescue protocol has been implemented (HCG 1500 IU / sc the day of the pick up + estradiol 4 mg + vaginal progesterone 400 mg daily) and fresh embryo transfer.

Description

Inclusion Criteria:

AMH ( antimullerian hormone) > 3.5 ng / ml, AFC (antral follicles count) > 15 follicles and if more than 18 follicles with diam. 12mm to induction

Exclusion Criteria:

high risk of OHSS ( ovarian hyperstimulation syndrome)

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
patients underwent "rescue protocols" and fresh embryotransfer
they were patients with good prognosis with a mean age of 34.13 ± 4.42 years, with a good ovarian reserve
Drug: GnRH agonist
In High Responder patients (HR) (more than 18 follicles with diameter ≥ 12mm at ovulation induction), the trigger was obtained with triptorelin 0.2 mg sc. In this cohort if less of 18 oocytes were retrieved, patients were considered at intermediate risk of OHSS and fresh transfer was performed. An adequate support of the luteal phase was initiated: HCG 1500 IU / sc the day of the pick up + estradiol 4 mg + vaginal progesterone 400 mg daily (Rescue protocol).
Other Names:
  • GnRH trigger

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 (OPR)
Time Frame: 2013-2018
presence of gestational sac and fetal hearts beats showed on unltrasonography 7/8 weeks after embryo transfer
2013-2018

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2013

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
