Trial summary

Recurrent implantation failure (RIF) occurs after women undergo in vitro fertilization and have multiple embryos transferred but no resulting pregnancies. RIF is a very challenging clinical entity for the reproductive physician and the patient. Read more about this study

About this study

Official title: Assessing the Optimal Duration of Progesterone Supplementation Prior to Transfer of Frozen Embryos in the Recurrent Implantation Failure Population

Recurrent implantation failure (RIF) occurs after women undergo in vitro fertilization and have multiple embryos transferred but no resulting pregnancies. RIF is a very challenging clinical entity for the reproductive physician and the patient. In fact, there is not even an agreed upon definition in the medical community. Many potential causes have been investigated over the past several years but no clear answer has emerged. Interest has recently turned to the endometrium, or the lining of the uterus. Studies have shown that the genes that are turned on in the endometrium vary based on how long this tissue has been exposed to progesterone, an important hormone that prepares the uterine lining for implantation of the growing embryo. In some women, it seems that they require longer periods of progesterone exposure to reach the same state of readiness. We hypothesize that an even larger proportion of women in RIF population will require longer treatments with progesterone.

In this study, we will randomize women with RIF who are about to undergo a frozen embryo transfer to one of two groups. The first group will have their embryo transfer done on the standard sixth day of progesterone treatment. The other group will have their transfer done on the seventh day of progesterone. We will be comparing the clinical pregnancy rate of the two groups as well as the live birth rate and miscarriage rate. We expect that extending the progesterone treatment by one day will increase the pregnancy rate of women with RIF.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PrometriumDrug

    The intervention will involve delaying the transfer of a frozen-thawed embryo into the uterus to increase the duration of progesterone exposure.

Study groups in NCT03504345
Study groupRoleWhat they receive
Control GroupActive comparatorThis arm of the study will have their frozen-thawed embryo transfer take place on the sixth day of progesterone supplementation (Prometrium), which is the standard protocol in our clinic.

What is being measured

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

  1. clinical pregnancy rate

    Rate of pregnancy, evidenced by clinical (fetal heartbeat) or ultrasound parameters (ultrasound visualization of a gestational sac, embryonic pole with heartbeat). It includes ectopic pregnancy.

    Measured: 6 to 8 weeks after embryo transfer

Secondary outcomes (2)
  1. Live birth rate

    Rate of birth in which a fetus is delivered with signs of life after complete expulsion or extraction from its mother, beyond 20 completed weeks of gestational age

    Measured: Approximately 9 months after embryo transfer

  2. Miscarriage rate

    Rate of natural death of embryo or fetus, after reaching clinical pregnancy stage and at or before 10 weeks gestation.

    Measured: Approximately 3 months after embryo transfer

Questions about this trial

What is this clinical trial studying?

A study testing Prometrium in people with Infertility Due to Nonimplantation and Infertility, run by Mount Sinai Hospital, Canada.

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 2 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: status not confirmed, as of the sponsor's last update on 20 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Crystal Chan, MD, MSc, FRCSC (416-586-4800 ext. 6024, crystal.chan@sinaihealthsystem.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

clinical pregnancy rate (time frame: 6 to 8 weeks after embryo transfer). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Apr 2018.
