Pregnancy and Medically Assisted Conception in Rare Diseases (EGR2)

March 23, 2026 updated by: Assistance Publique - Hôpitaux de Paris

Prospective Observational Study About Pregnancy and Medically Assisted Conception in Rare Diseases

Rare diseases frequently affect women of childbearing age. Pregnancy in these women has become less rare, but remains associated with high levels of complications. One obstacle to their optimal management during pregnancy is that there are no prospective studies of pregnancy during rare diseases and several connective tissue diseases. As a consequence, the management of these pregnancies is non-standardised in terms of treatment, monitoring (frequency of consultations, laboratory tests and ultrasound), and organisation of care.

Moreover, although these women (all diseases combined) are frequently exposed to medications potentially incompatible with pregnancy, little is known about the frequency of these exposures and especially their consequences to mother and child.

For these reasons, researchers and clinicians from different specialties created an interdisciplinary research group on pregnancy and rare diseases (GR2), intended to improve the management of these patients' pregnancies. Using a single computer server, the investigators plan to set up a large prospective study of pregnancies in patients with rare diseases: various forms of myositis, lupus, antiphospholipid syndrome, Sjogren syndrome, scleroderma, and inflammatory rheumatic diseases. The investigators objective is to analyse the complications of pregnancies in women with rare diseases and then to improve their management and their quality of life.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
"good" obstetric outcome
Time Frame: 35 week gestation until 1 year Post Partum
It's a composite outcome . A pregnancy with no severe maternal complication (by the Epimoms* definition), live birth after 35 weeks' gestation, a birth weight >10th percentile of the general population and no infections (maternal and infant) during pregnancy and first year of follow up, respectively
35 week gestation until 1 year Post Partum

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Define the best therapeutic management strategies
Time Frame: 2 years
About the organisation of care (analysis of the effect on outcome of the number of ultrasound examinations and clinician visits, and the systematic planning of delivery)
2 years
Conduct pharmacoepidemiologic studies
Time Frame: 2 years
Analyse the frequency of exposure to various medications (immunosuppressors, biological therapy, corticosteroids) and their maternal and fetal consequences (e.g., infectious complications).
2 years
Analyse the frequency of exposure to various medications (immunosuppressors, biological therapy, corticosteroids) and their maternal and fetal consequences (e.g., infectious complications).
Time Frame: 9 months
Within an existing collection with (1) samples taken during the first trimester of pregnancy to analyse markers that might predict subsequent obstetric complications (cytokines, growth factors, enzymes) (2) with cord blood samples (which will, in particular, enable immunological and pharmacological analyses).
9 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2015

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
June 1, 2025

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
