Polymyalgia rheumatica (PMR) is prevalent among elderly. Untreated, it leads to major reduction in quality of life. Glucocorticoids are the cornerstone of treatment, but have drawbacks, warranting glucocorticoid sparing treatment. A proof of concept study on Rituximab (RTX) vs placebo showed efficacy in 48 vs 21%(p=0.049) in glucocorticoid free remission after 21 weeks (Marsman et al. 2021). Though promising, the short study duration and small sample size require further confirmation. Therefore a larger randomised controlled trial with longer follow up will be performed on RTX efficacy on glucocorticoid free remission in newly diagnosed PMR patients during glucocorticoid taper.
