Arthritis Clinical Trials in Phoenix, AZ

The COVID-19 VaccinE Response in Rheumatology patients (COVER) study is a multicenter randomized controlled trial designed to evaluate the efficacy and safety of a mRNA COVID-19 vaccine supplemental dose (booster) in patients with autoimmune conditions and to evaluate the impact of different immunomodulatory therapies on vaccine response. The investigators propose to recruit up to 1000- patients with autoimmune conditions who have a completed 2-dose regime of mRNA COVID-19 vaccine (>28 days prior) and who are planning to receive an additional dose of mRNA COVID-19 vaccine (i.e., booster). Participants in this study will be men and women 18 years and older with confirmed rheumatic disease, including psoriatic arthritis (PsA), axial spondyloarthritis (SpA) and rheumatoid arthritis (RA) who express a decision to receive the mRNA vaccination booster within 30 days post enrollment. A primary objective of this study is to test the hypothesis that holding certain medications for a brief period of time around the time of COVID-19 vaccination might improve the response to the vaccine while not unduly having safety concerns with respect to the effects of their disease. During the study, participants using the immunomodulatory therapies described outlined in protocol will be randomized to temporarily hold (for 2 weeks) versus continue after they receive the COVID-19 vaccine supplemental dose. Patients who temporarily stop one of their medications for their autoimmune inflammatory disease may be at increased risk of flares of their autoimmune condition. If these occur, they are expected to occur within 2 - 4 weeks of treatment interruption. Detailed protocol outlines the hold schedules for the therapies to be randomized in this study. Read Less

Previous motion analysis studies have demonstrated excellent ability to distinguish subtle differences in gait between normal subjects and those suffering from arthritis. With proper techniques and analysis differences between osteoarthritis patient groups can be distinguished. Previous research has indicated that subjects who received a single-radius design total knee replacement have superior gait performance that those who received a multi-radius design total knee replacement. The DJO Global Empowr PS Knee System is a single-radius lateral pivot design. This design should achieve reproducible more natural knee function and improved patient outcomes and satisfaction. A motion analysis laboratory will be used to collect gait data from patients who are going to receive a Empowr PS knee device and also from age-matched control subjects. These data will be compared with data previously collected from patients who received Stryker Triathlon devices, Biomet Vanguard devices and age-matched healthy control subjects. Read Less
