Trial summary

It has been reported that low-dose aspirin and Heparin would lead to an increased Pregnancy rate in patients undergoing IVF-ET. Low-dose aspirin may improve uterine and ovarian perfusion and that aspirin might enhance endometrial receptivity and ovarian responsiveness as well, which could result in better implantation… Read more about this study

About this study

Official title: To Evaluate the Effect of Low Dose Aspirin in Increasing the Chance of Pregnancy in Frozen Embryo Transfer Cycles

It has been reported that low-dose aspirin and Heparin would lead to an increased Pregnancy rate in patients undergoing IVF-ET. Low-dose aspirin may improve uterine and ovarian perfusion and that aspirin might enhance endometrial receptivity and ovarian responsiveness as well, which could result in better implantation and pregnancy rates after IVF or ICSI treatment. This study assesses potential effects of low-dose aspirin (100 mg daily) on pregnancy rate following frozen embryo transfer.

Read the detailed description

In the present randomized double-blind prospective study, the patients will be randomly assigned to the study and control groups. With the onset of endometrial preparation and estrogen treatment, the study group will receive 100 mg of oral aspirin and the control group will be given placebo. When endometrial thickness will be found between 8-14 mm, therapy with progesterone (100 mg IM daily) will be started and embryo transfer will be performed 48 to 72 hours later. Doppler ultrasonography also is done to calculate Resistive Index (RI) and Pulsatility Index (PI), the day after progesterone administration.

βHCG will be assessed 14 days after ET. If a pregnancy will be achieved, the patients in study and control groups will be instructed to continue the aspirin or placebo through 5 weeks and if the pregnancy test result will be negative, the treatment with aspirin or placebo will be stopped. The patients will be followed until 20 weeks of gestation and the results of treatment cycle will be compared in two groups.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Asprin in people with Infertility, run by Royan Institute at 1 site in Iran.

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 3 inclusion and 1 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 18 Jan 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 Iran. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Pregnancy rate (time frame: 6 weeks). 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 18 Jan 2017.
