Trial summary

Currently all patients that have freeze-all ICSI treatment cycles have the start of their FET cycle scheduled with the use of OCP. While an excellent pregnancy rate (75%) for the patients that have a blastocyst transfer has been maintained over time, 15% of started FET cycles are being cancelled because of premature… Read more about this study

About this study

Official title: Down-regulated Hormonally Controlled Cycles for Vitrification-warmed Blastocyst Transfers: Reduces Time to Transfer and Cycle Cancellation

Currently all patients that have freeze-all ICSI treatment cycles have the start of their FET cycle scheduled with the use of OCP. While an excellent pregnancy rate (75%) for the patients that have a blastocyst transfer has been maintained over time, 15% of started FET cycles are being cancelled because of premature luteinization, and the treatment (to transfer) takes approximately 89 days. The use of a Lucrin depot may reduce the number of cycles cancelled and reduce the treatment time to approximately 69 days. The use of no drugs and allowing the normal menstrual cycle to determine the time to start the FET cycle may suit some patients. Whether these benefits can be obtained while still maintaining the current FET pregnancy rate will be the main focus of the trial.

Read the detailed description

The patients will undergo standard assisted conception procedures; controlled ovarian stimulation (COS), oocyte pickup procedure (OPU), ICSI, embryo culture, blastocyst vitrification and frozen embryo transfer. If sufficient (>2) viable blastocyst develop from the in vitro culture of their embryos, all viable blastocysts will be cryopreserved using a routine vitrification procedure. This is the eligible patient population. On the day the last blastocyst(s) are frozen the patients will be given a further opportunity to ask questions and if satisfied they will be asked to complete a trial consent. At this point patients will be randomized by numeric code and given a schedule and drug prescription for scheduling the start of their hormone supplemented frozen embryo transfer cycle. During the scheduling period the patients will follow the drug prescription provided . After the completion of their treatment - the transfer of one or two vitrified-warmed blastocyst - the patients from both groups will receive identical luteal support drug schedules and prescriptions. A blood test will be performed on the 15th day of progesterone supplementation, to determine the βhCG blood concentration. Currently at Antalya IVF, approximately 75% of patients who have blastocysts transferred in a frozen embryo transfer cycle have a positive biochemical pregnancy test, >29 international units per litre (IU/L) of human chorionic gonadotropin (βhCG). If pregnant, patients will continue using estrogen and progesterone supplementation for a further 8 weeks. At 7 weeks of gestation (5 weeks after embryo transfer ) the patients will receive a transvaginal ultrasound scan (TVUS) to check for pregnancy viability (fetal sac with cardiac activity). Thereafter the patients will have regular TVUS to follow fetal development. At 20 weeks of gestation a TVUS will be performed to confirm an ongoing pregnancy (normal fetal development).

All drug packs are delivered to the clinic by the pharmacy after receiving the prescription. A staff member will verify the code on the prescription with randomization code allocated to the patient. The pack will then be given to the patient after verbally confirming patient identity. The packs will also contain a drug use instruction sheet and a trial information sheet.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cycle cancellation

    blood progesterone concentration (>2nmol/L) as a measure of premature luteinization

    Measured: On day 14 of estrogen supplementation

Secondary outcomes (1)
  1. Ongoing pregnancy rate

    TVUS normal fetal development >20 weeks of gestation, in case of a pregnancy

    Measured: 20 weeks of gestation

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 1 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: withdrawn, as of the sponsor's last update on 26 May 2016. 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 Turkey (Türkiye). 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 was withdrawn before enrolling participants, so there are no results.

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?

Cycle cancellation (time frame: On day 14 of estrogen supplementation). 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 NCT02238431, which also lists 3 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 26 May 2016.
