Karlsson (control exposed to IFN) 2014 |
Worldwide Until 2011 retrospective cohort |
9 clinical studies in the fingolimod clinical development program. | Fingolimod treatment at the time of conception or within 6 weeks prior to conception. |
exposed to other treatment, sick
Interferon beta-1a treatment at the time of conception or within 6 weeks prior to conception. |
1st trimester | 66 / 4 | Malformations: Numeratos: addition of anomalies in newborn and ETOP; Denominators: newborn and fetus with available information. The duration of in utero fingolimod exposure in the majority of live births was estimated to be >8 weeks to <=12 weeks. | |
Patients received treatment provided by the investigator in clinical trial. | ||||||||

International 2005 - 2016 prospective cohort |
The Multiple Sclerosis (MS) Base Registry is a large, international observational cohort study, with long-term prospectively collected data. | Pregnancies occurring during Fingolimod therapy. (This is a subgroup of exposure among the exposed group considered in the study). |
exposed to other treatment, sick
Pregnancies occurring during Interferon beta (all) therapy. (This is a subgroup of exposure among the exposed group considered in the study). |
during pregnancy (anytime or not specified) | 21 / 350 | ||
Data in the MSBase registry, including prospective pregnancy data, is entered in real time or near real time, as part of routine clinical visits. Information collected included: disease-modifying therapies exposure before and during pregnancy. | ||||||||

Pauliat 2020 |
Germany, Switzerland, Israel, France, Spain, Turkey, Australia 2000 - 2017 prospective cohort |
Eight participating Teratology Information Services (TIS) and nine pharmacovigilance centers. | Pregnant women having used fingolimod during the first trimester. |
exposed to other treatment, sick
Pregnant women having used IFN-beta during the first trimester. |
1st trimester | 63 / 62 | Fingolimod was discontinued at a median gestational age of 6 weeks (IQR 5-7, min 3, max 19). Exclusion criteria for both groups included exposure during pregnancy to any known major teratogen or fetotoxicant and to any treatment for malignancy. | |
Maternal information on medication exposure (indication, timing in pregnancy, duration, dose and concomitant medication) were collected at initial contact. |
