Luteal Phase Support In IVF Women Using GnRH Agonist
An observational study of IVF and Luteal Phase Defect, run by National University of Malaysia at 1 site in Malaysia.
Trial summary
Lately, the role of GnRH agonist as luteal phase support has been recommended by various studies though the mechanism is still debatable. It has been postulated that GnRH agonist might support the corpus luteum by stimulating the secretion of luteinizing hormone by pituitary gonadotroph cells, or by acting directly on… Read more about this study

About this study
Official title: A Comparison Of Progestogens Plus GnRH Agonist Versus Progestogens Only In Luteal Phase Support In IVF Women: A Retrospective Single Centre Experience
Lately, the role of GnRH agonist as luteal phase support has been recommended by various studies though the mechanism is still debatable. It has been postulated that GnRH agonist might support the corpus luteum by stimulating the secretion of luteinizing hormone by pituitary gonadotroph cells, or by acting directly on the endometrium through the locally expressed receptors.
Therefore, this study was designed to evaluate effects of the additional of single-dose GnRH agonist to the routine progestogens use for luteal phase support on IVF outcome as compared to progestogens only. The biochemical pregnancy rates, clinical pregnancy rates, live birth rates and miscarriage rate between these regimes were compared. The hypothesis of this study was women with addition of GnRH agonist as luteal phase support have higher biochemical pregnancy rate, clinical pregnancy rate and live birth rate compare to patient with progestogens only luteal phase support.
Read the detailed description
This was a retrospective study on selected patients who underwent IVF treatment under MAC (Medically Assisted Conception) Unit, University Kebangsaan Malaysia Medical Centre for the period of June 2015-June 2018. Their medical records were reviewed, and data analysed.
The sample size was calculated using Power \& Sample Size Calculator by Dupont \& Plummer 1998 for dichotomous response version 3.1.2 [6]. Based on this formula, a is the type I error probability for a two-sided test allowable about 5% in this study. The power of certainty is the percentage of estimated power of this study. On the other hand, p0 is the probability of the outcome for GnRH agonist used as luteal phase support by Zafardoust et al. [7] which is 30% (0.30). The p1 is the probability of the outcome in an experimental subject which expected in this study based on similar objective of higher rate of implantation with GnRH agonist. The investigators set the p1 is 0.50 as overall literature suggest that at cumulative successful of implantation post GnRH is around 30-50%. The m is the ratio of control to experimental subjects which is 1 to 1 in this study. Generated sample size from this program is 93 for one arm which result in total sample size is 186. The investigators then added 10% of additional sample for any bias or loss of data during follow up which concluded total sample size to be at least 200 samples (100 patients each arm).
All women who underwent control-ovarian stimulation (COH) regime using either gonadotrophin combination with GnRH antagonist protocol or mild stimulation protocol using oral letrozole or clomiphene citrate were included in this study. All women underwent follicle tracking by transvaginal ultrasound until dominant follicle size reached (>18mm). IM Ovitrelle (6500 IU) was given and proceed with oocyte retrieval (OR) at least 35-36 hours under transvaginal ultrasonography guidance. The 17-gauge single -lumen needles used for oocyte retrieval under sedation.
ICSI were performed according to local protocol. Zygotes were cultured up to day 5 in G1 medium (Vitrolife). On day 5, embryos were graded according to previously described criteria. One or two embryos were transferred, depending on the morphological score and the developmental stage of the embryo, as well as the age of the patient.
Regardless the ovarian stimulation protocols, these women were assigned into two group; progestogens with additions of GnRH agonist and progestogen only for luteal phase support. Both groups were given routine progestogen support for two weeks duration started from the day of embryo transfer. This includes oral progestogen (Tablet Duphaston 10mg tds), vaginal progestogen (vaginal utrogestan 400mg bd) or intramuscular (IM Proluton 250 mg weekly) as prescribed by attending clinician .
In the first group, there were additional GnRH agonist administrated as a single dose of 0.2 mg decapeptyl given at day 3 after ICSI. The other group with no GnRH agonist given was the control group.

It has been postulated that GnRH agonist might support the corpus luteum by stimulating the secretion of luteinizing hormone by pituitary gonadotroph cells, or by acting directly on the endometrium through the locally expressed receptors.
Therefore, this study was designed to evaluate effects of the additional of single-dose GnRH agonist to the routine progestogens use for luteal phase support on IVF outcome as compared to progestogens only.

Questions about this trial
What is this clinical trial studying?
An observational study of IVF and Luteal Phase Defect, run by National University of Malaysia at 1 site in Malaysia.
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 2 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 25 Nov 2019. 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 Malaysia. 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?
Biochemical pregnancy rate (time frame: 14 days after embryo transfer). The study lists 3 primary outcomes in all. 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 NCT04174378, which also lists 24 linked publications.
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 25 Nov 2019.
