Burlington, Massachusetts--(Newsfile Corp. - November 9, 2026) - Lifordi Immunotherapeutics, Inc., a clinical-stage biotechnology company developing antibody-drug conjugates (ADCs) for the treatment of autoimmune and inflammatory disorders, presented Phase 1 clinical data for LFD-200, the Company's novel subcutaneously (SC) administered ADC delivering a potent glucocorticoid (GC) directly to immune cells, at the American College of Rheumatology (ACR) Convergence 2026 conference. Phase 1 data from healthy participants (HPs) demonstrated LFD-200 was well tolerated with dose-responsive anti-inflammatory effects and did not affect serum cortisol, a sensitive marker for systemic GC toxicity. Data from patients with moderate to severe rheumatoid arthritis (RA) treated with LFD-200 in the ongoing Phase 1b study are anticipated by the end of 2026.
