Multiple Sclerosis, Multiple Sclerosis, Relapsing-Remitting

The primary objective(s) of the study is to evaluate the impact of exposure to SC Peginterferon beta-1a or IM Interferon beta-1a before and during pregnancy on pregnancy outcome in female participants who had registered in the German Patient Support Program (PSP) and of whom a pregnancy report and pregnancy outcome report is available. The secondary objectives of this study are applicable for a subpopulation of the above-mentioned population, i.e. for participants of whom data on a standardized questionnaire collected during a telephone interview is available.

This is an observational study with focus on existing pregnancy reporting forms (retrospective part) and a patient's questionnaire which is completed at a single point of time (prospective part). Main data source for the retrospective data (from 2014 until December 2019) will be captured from multiple sclerosis service-center (MSSC) database, i.e. the entered pregnancy report (to be completed as soon as pregnancy becomes known) and pregnancy outcomes report (to be completed after completion of pregnancy). Prospective data (December 2020 to 31 March 2021) will be captured as standardized ePDF questionnaire completed during telephone interview. If the pregnancy report or the pregnancy outcome report is incomplete, i.e. the data above was not collected, the open questions will be addressed during a telephone interview performed by the MSSC and the new information will be entered into the MSCC database. The patient questionnaire will be completed at a single point of time during the telephone interview performed by the MSSC.
