Application of the Personalized N-of-1 Trial Design in Patients With Rheumatoid Arthritis

Sponsor: Tufts Medical Center

View on ClinicalTrials.gov

Summary

The goal of this N-of-1 study is to learn about treatment for individual patients who have rheumatoid arthritis (RA,) for which many treatments are available. The treatments are different in how they work, the way they are given, side- effects, and cost. While treatment guidelines are available, finding the best treatment order of treatments is often based on physician choice. The main question this study aims to answer are: * What are the effects of different treatments on RA symptoms and condition for each individual patient * What is the effectiveness of different treatments across all patients enrolled in the N-of-1 study Participants will be enrolled and randomized to a sequence of three U.S. Food and Drug Administration (FDA) approved RA medications: 1. etanercept, 2. adalimumab, 3. upadacitinib 4. tocilizumab. Participants will be asked to complete questionnaires about their condition and quality of life fortnightly, monthly and/or quarterly (either in clinic or remotely) and report their level of pain on alternate days (remotely).
