About this study

Official title: GnRHa Trigger in Asian Oocyte Donors Co-treated With a GnRH Antagonist - a Dose Finding Study

The aim of this randomized single center study is to explore the most optimal dose of GnRHa used for triggering of final oocyte maturation in IVF. The study group will consist of oocyte donors who have GnRHa trigger as a standard trigger concept.

Hypothesis: In an Asian oocyte donor population, the use of 0.2 mg, 0.3mg or 0.4 mg of GnRHa will lead to the retrieval of comparable numbers of mature oocytes (MII) and good quality embryos. Moreover, the reproductive outcome in the recipients will be similar regardless of the dose of GnRHa used for trigger.

Methods

A randomized controlled single center study. All oocyte donors, fulfilling the inclusion criteria, will be eligible for inclusion after randomization.

Stimulation, monitoring, oocyte pick-up in donors and embryo transfer in recipients On day two of the cycle, - i.e. prior to commencing stimulation with long acting FSH (Elonva) - donors will be randomized to one of three groups, using different doses of GnRHa (Triptorelin) for trigger. Stimulation will be performed according to the standard stimulation protocol of the clinic, using Elonva followed by co-treatment with a GnRH antagonist from day 5 of stimulation . The dose of Elonva used for stimulation will be either 100 or 150 µg according to the weight of the patient. The first transvaginal ultrasound scan (TVUS) will be performed after seven or eight days after the Elonva depot injection. As soon as two follicles have reached a size of ≥ 17mm, triggering of final oocyte maturation will be performed with one single bolus of Triptorelin, 0.2 mg, 0.3mg or 0.4 mg. The timing of the trigger will be 6 AM for all groups and the oocyte pick-up (OPU) will be performed after 34 hours, according to the usual practice of the clinic. Importantly, each patient will be asked to check the presence of an LH surge via a urine LH detection kit at 4 hours after the trigger bolus has been administered. Embryo transfer will be performed on day two in all recipients.

Study group I Stimulation according to the abovementioned and ovulation trigger with 0.2mg Triptorelin. All other procedures will be performed according to the practice of the clinic.

Study group II Stimulation according to the abovementioned and ovulation trigger with 0.3mg Triptorelin. All other procedures will be performed according to the practice of the clinic.

Study group III Stimulation according to the abovementioned and ovulation trigger with 0.4mg Triptorelin. All other procedures will be performed according to the practice of the clinic.

Randomization Randomization will be performed using sealed envelopes developed via a computer generated list with blocks of twelve. The randomization will be performed on day two of the cycle. Doctors will be blinded to the randomization, but not patients and nurses.

Follicular fluid (FF) collection FF from the first punctured follicle on each side will be collected and cryo-preserved at -20 degrees for subsequent analysis of steroids.

Granulosa cell gene-expression analysis Cumulus and mural granulosa cells will be preserved and snap-frozen from a sub-group of 10 patients in each group. The primary subsequent analysis will focus on possible differences in LHR gene expression according to GnRHa trigger dose.

Questions about this trial

What is this clinical trial studying?

A study testing Triptorelin in people with Normal Oocyte Donors, run by Vietnam National University at 1 site in Vietnam.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Vietnam. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of mature oocytes (time frame: 30 minutes after oocyte retrieval completed). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02208986, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2017.
