Juvenile Dermatomyositis clinical trials at UCLA

This is a randomized, multi-site, adaptive, open-label clinical trial comparing the immune response to different additional doses of COVID-19 vaccine in participants with autoimmune disease requiring IS medications. All study participants will have negative serologic or suboptimal responses (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result ≤200 U/mL) or a low immune response (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result >200 U/ml and ≤2500 U/mL) to their previous doses of COVID-19 vaccine. The study will focus on 5 autoimmune diseases in adults: - Systemic Lupus Erythematosus (SLE) - Rheumatoid Arthritis (RA) - Multiple Sclerosis (MS) - Systemic Sclerosis (SSc), and - Pemphigus. This study will focus on 4 autoimmune diseases in pediatric participants: - Systemic Lupus Erythematosus (SLE) - Juvenile Idiopathic Arthritis (JIA) - Pediatric-Onset Multiple Sclerosis (POMS) - Juvenile Dermatomyositis (JDM)
