A team at Charit\u00e9 \u2013 Universit\u00e4tsmedizin Berlin treated six patients with a CD19-directed CAR-T cell therapy. Disease activity fell in all of them, and three patients reached sustained, medication-free remission. The results appeared in late August 2026 in the journal Nature Medicine.<\/strong><\/p>\n<h3 class=\"wp-block-heading\">Rebooting a misfiring immune system<\/h3>\n<p class=\"wp-block-paragraph\">In CAR-T cell therapy, a patient&#8217;s own immune cells are engineered in the lab to recognise and destroy the B cells that drive disease. In the trial, known as COMPARE, the six patients \u2013 three women and three men aged 31 to 69 \u2013 received a single infusion of the product mivocabtagene autoleucel after conventional antirheumatic drugs had failed.<\/p>\n<p class=\"wp-block-paragraph\">After treatment, autoantibody levels dropped sharply and inflammatory foci in the joints were no longer detectable. Lead investigators David Simon and Gerhard Kr\u00f6nke describe the effect as a targeted &#8220;reset&#8221; of the part of the immune system that fuels the inflammation.<\/p>\n<h3 class=\"wp-block-heading\">Small sample, early stage<\/h3>\n<p class=\"wp-block-paragraph\">Despite the encouraging data, the researchers urge caution. This is the world&#8217;s first trial of its kind, involving just six patients. Responses varied, and in one person the disease returned after an initial remission. At this early stage, no claim of a cure can be made. A larger comparative study with ten more patients is planned.<\/p>\n<p class=\"wp-block-paragraph\">Sources: <a href=\"https:\/\/www.nature.com\/articles\/s41591-026-04603-3\" target=\"_blank\" rel=\"noopener\">Nature Medicine<\/a>, <a href=\"https:\/\/www.sciencedaily.com\/releases\/2026\/08\/260828082330.htm\" target=\"_blank\" rel=\"noopener\">ScienceDaily<\/a>, <a href=\"https:\/\/www.genengnews.com\/topics\/translational-medicine\/car-t-cell-therapy-puts-severe-rheumatoid-arthritis-into-remission-in-first-clinical-trial\/\" target=\"_blank\" rel=\"noopener\">GEN<\/a><\/p><div id=\"netgu-3526600312\" class=\"netgu-after-content netgu-entity-placement\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-6258556257245998\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-6258556257245998\" \ndata-ad-slot=\"4559785002\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({});
