Clinical trial NCT02706470: Use of Cyclosporin A for the Treatment of Recurrent Miscarriage
Official title: A Randomized, Controlled Trial of Cyclosporin A for Women With Unexplained Recurrent Miscarriage
Study type: INTERVENTIONAL
Overall status: UNKNOWN
Phase: PHASE2
PHASE3
Conditions: Miscarriage, Recurrent
Keywords: recurrent miscarriage; immunology
Lead sponsor: Fudan University
Sponsor class: OTHER
First posted: 2016-03-11
Enrollment: 384
Sex: FEMALE
Minimum age (years): 20
Maximum age (years): 40
Standard ages: ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: TREATMENT

Brief summary: The purpose of this study is to determine whether Cyclosporin A (CsA) - an immunosuppressant drug - in early pregnancy will reduce the risk of miscarriage in women who had a history of unexplained recurrent miscarriages, as compared with that treated with Dydrogesterone-an active comparator. The hypothesis is based on the evidence found in vitro and in vivo experiments that CsA can induce maternal-fetal tolerance so that it may reduce the risk of miscarriage.


Eligibility criteria: Inclusion Criteria:

* Both the woman and her husband agree to participate and sign the informed consent form.
* Have a history of two or more unexplained recurrent miscarriages.
* Spontaneous conception.
* Gestational age less than 5 weeks.
* Have a normal menstrual cycle (\>=23 and \<=35 days) and biphasic pattern of basal body temperature before pregnancy.
* No significant chromosomal aberrations in the couple.
* Semen quality tests show not apparent abnormalities in husband

Exclusion Criteria:

* Age below 18 or above 41 years at conception.
* Present pregnancy is a result of donor insemination or egg donation.
* Significant uterine anomalies detected by ultrasonography, hysterosalpingography, or hysteroscopy.
* Contraindications of CsA (e.g. severe infectious diseases, tumor or immunodeficiency) or Dydrogesterone.
* Smoking more than 20 daily.
