EPID Multiple Sclerosis Pregnancy Study

August 12, 2019 updated by: Bayer

Pregnancy Outcomes in Multiple Sclerosis Populations Exposed and Unexposed to Interferon β - a Register-based Study in the Nordic Countries

Multiple Sclerosis (MS) is the most common chronic neurologic disability in young adult females in their childbearing ages. Little evidence is available regarding the association between exposure to IFN-beta (β) products and adverse pregnancy outcomes. Therefore the four marketing holders of IFN-β are conducting a European-wide IFN-β pregnancy registry. Additionally, the Committee for Medicinal Products for Human Use (CHMP) has requested a study to enable identification of pregnancy outcomes in the MS population unexposed to IFN-β products for comparison with the ongoing European IFN-β Pregnancy Registry.

Study Overview

Detailed Description

Information will be obtained from the Drugs and Pregnancy Project database (DPP - FIN) and the Medical Birth Register (MBR - SWE, NOR). The Finnish DPP and Norwegian MBR include information on all stillbirths of foetuses with a birth weight of at least 500 g or with a gestational age of at least 22+0 Gestational Week (GW). The Swedish MBR includes data on stillbirths after 28 GW

The estimated number of pregnancies in MS patients needed is 1671, encompassing data from:

i) FIN: 1 January 1996 - 31 December 2014; ii) SWE: 1 July 2005 - 31 December 2014; iii) NOR: 1 January 2004 - 31 December 2014.

Study Population

The target study population consists of Finnish, Swedish and Norwegian women diagnosed with MS who have been pregnant during the study period from 1996 to 2014. The pregnancy may have resulted in an induced abortion, spontaneous abortion, ectopic pregnancy, stillbirth, or live birth during the study period.

Description

Inclusion Criteria:

  • Women who have had a pregnancy with a recorded outcome consisting of an induced abortion, spontaneous abortion, ectopic pregnancy, or birth during the study period in FIN, SWE or NOR with the event being documented in the relevant databases.
