Cabaletta Bio Unveils Breakthrough Research on Rese-cel
Cabaletta Bio Highlights Rese-cel Progress at ACR Convergence 2025
Cabaletta Bio, Inc. (NASDAQ: CABA), a leading biotechnology company focused on innovative cell therapies for autoimmune diseases, has presented promising clinical data for its investigational treatment, rese-cel (resecabtagene autoleucel), at the ACR Convergence 2025 conference. With multiple oral and poster presentations, these updates underline the potential of rese-cel in addressing complicated autoimmune disorders.
Positive Outcomes in Myositis Trials
Key Developments
In the Phase 1/2 DM/ASyS cohort, every myositis patient who met significant registrational criteria saw major improvements without the use of immunomodulators. This marks a remarkable achievement for patients undergoing treatment for dermatomyositis and antisynthetase syndrome. Cabaletta aims to initiate a myositis registrational trial this quarter that seeks to enroll 14 patients and evaluate the effectiveness of rese-cel over a 16-week period.
Clinical Response Encouragement
Results have shown that in a cohort of systemic sclerosis patients, all participants exhibited significant improvements without the use of immunomodulators or steroids. This clinical response is crucial as it hints at rese-cel’s ability to reset the immune responses, providing hope for systemic sclerosis patients.
Enhancements in Lupus Treatment Strategies
RESET-SLE Trial Expansion
Cabaletta has expanded the RESET-SLE trial, responding to favorable clinical feedback. So far, seven out of eight lupus patients have exhibited significant clinical responses. With plans to integrate a no preconditioning cohort, the company anticipates the release of initial data in 2026. This expansion allows for inclusion of lupus patients who request therapies without preconditioning, especially important for women of child-bearing potential.
Trial Statistics and Inclusion
As of late October 2025, 76 patients had been enrolled across 77 trial sites worldwide. Cabaletta’s strategic approach to expanding its trials demonstrates a commitment to ensuring that more patients have access to promising therapeutic options.
