Trial summary

Miscarriage occurs in about 1-2% of human pregnancies and is one of the common pregnancy problems before 12 weeks of pregnancy. Anatomical and chromosomal abnormalities, microbial factors and auto and alloimmune reactions have been speculated to attribute in recurrent miscarriage. Read more about this study

About this study

Official title: Effect of IVIg on Pregnancy Rate of Patient With Recurrent Pregnancy Loss With Immunological Causes

Miscarriage occurs in about 1-2% of human pregnancies and is one of the common pregnancy problems before 12 weeks of pregnancy. Anatomical and chromosomal abnormalities, microbial factors and auto and alloimmune reactions have been speculated to attribute in recurrent miscarriage. Unexplained recurrent miscarriage (URM) is defined as three or more repeated abortions, probably caused by maternal immunological rejection . Given that maternal immune system encounters semi-allogeneic fetus, pregnancy outcome is associated with the interaction between maternal immune system and immuno-regulatory capability of the fetus. Effectiveness of treatment approaches in RM patients has been controversial and remained to be discovered. Immunomodulatory agents such as corticosteroids and allogeneic lymphocyte immunization showed variable success rates in RM patients. Therapeutic effects of IVIG in unexplained RM is controversial and most positive results were obtained from the trials in RM women with cellular immune abnormalities, such as increased NK cell level and/or cytotoxicity, and T cell abnormalities. Previous studies have shown that the incidence of genetic abnormalities in children who have received immunosuppressive drugs such as IVIg like normal people and normal society. In this study we used IVIg at the time of positive pregnancy,400 mg/kg IVIG was administered intravenously. Following the first administration, IVIG well given every 4 weeks through 32 weeks of gestation to suppress the immune system in patients with immunological causes of RPL and the results will be compared with a control group that did not receive any type of drug.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 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 17 Sep 2018. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Changes in NK cells, T reg and Th17 cells frequency. (time frame: up to 8 month of pregnancy). 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 NCT03174951, which also lists 7 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 17 Sep 2018.
