Pharmacoepidemiology

Within large clinical-epidemiological cohort studies, the Pharmacoepidemiology Working Group comparatively examines the long-term safety and effectiveness of new antiinflammatory rheumatic drugs. Our goal is to provide physicians and patients with reliable evidence of the safety profile under everyday conditions and thus to increase the safety of therapy for risk groups.

Since 2001, patients with rheumatoid arthritis have been included in the Biologics Register RABBIT. These patients start therapy with a biological, biosimilar, JAK inhibitor or, as a comparison group, a conventional synthetic DMARD after failure of a previous DMARD. They are monitored for at least 5 and up to 10 years. About 450 institutions throughout Germany have documented almost 20,000 patients so far.

Numerous new and clinically significant insights have been gained, e.g. on the risk of infection, mortality, rare adverse events and their risk factors, efficacy under everyday conditions or quality of life (see drug safety). RABBIT is one of the world’s largest biologics registries in rheumatology and cooperates closely with other European registries.

In 2017, RABBIT-SpA was launched as a further disease registry for patients with axial spondyloarthritis and psoriatic arthritis, whose disease progression is observed under conventional or new therapies similar to RABBIT. As of September 2020, 2,000 patients are included. For the analysis of biomarkers we cooperate with the Fraunhofer Institute for Molecular Biology in Frankfurt (IME).

Within the framework of the BMBF funding of musculoskeletal research networks, we have been coordinating the TARISMA (Targeted Risk Management in Musculoskeletal Diseases) network since May 2020, in which a total of 6 network partners from Berlin, Bremen and Greifswald are involved. Using data from RABBIT, we are investigating the significance of chronic comorbidities such as interstitial lung disease, heart failure or depression for disease progression and mortality. In RABBIT-SpA detailed data on medication, adherence and patient-reported outcomes are collected with the help of a medical app and linked to existing clinical data.

There is a large evidence gap regarding the drug therapy of pregnant women with rheumatic diseases. Since 2015, in cooperation with the Heinrich-Heine-University of Düsseldorf we have therefore been investigating the course of pregnancies from the time of the actual desire to have children in the Rhekiss Pregnancy Register. We collect prospective data on the course and outcome of the pregnancy and the development of the child until its second birthday. The results will help to improve the counselling and management of women suffering from rheumatic diseases during the desire for children and during pregnancy.

Together with the European network of pregnancy registers EuNeP, which is also led by our group and supported by the FOREUM Foundation, collaborative evaluations on the course and outcome of pregnancy will be carried out.

In view of the COVID-19 pandemic, the group has actively participated in the establishment of the German and European COVID-19 registry. Anja Strangfeld and Anne Regierer are members of the steering committee of the German and Anja Strangfeld is a member of the steering committee of the European registry. Due to the international cooperation, important insights into the special situation of patients with autoimmune diseases under immunosuppression could be gained very quickly.

The group is continuously developing both the technical prerequisites of data acquisition (online registry, patient apps, automated monitoring) and the methodological basis of data analysis.
