The MAMA Study

09/09/2026

Find out what’s in a MAMA Welcome Pack! Each participant in MAMA will be sent a Welcome Pack stuffed with items to help you during your time in the study.

The MAMA Study is designed to find out whether it is better for women who have inflammatory arthritis and are pregnant to temporarily stop or to continue taking biologic medications.

Both continuing and stopping using biologics beyond 28 weeks of pregnancy are routine practice in the UK; this varies between hospitals. The MAMA Study is looking to provide an answer on which is the better approach.

We are hugely grateful for the support of some wonderful networks and charities, including Arthur's Place, a digital magazine and social network for young adults with arthritis. Thank you for your support Arthur's Place!

I wanted to start a family straight after getting married, so it was important that I find out how to do that safely on my arthritis medication.
