Cabaletta Bio announced new clinical and translational data from the first four patients in the lowest dose cohort in RESET-PV evaluating preconditioning-free rese-cel and initial manufacturing and translational data from the first two autoimmune patients treated with rese-cel manufactured using the automated Cellares Cell Shuttle platform in the RESET clinical development program. "Based on our view that a higher rese-cel dose would be required in the absence of preconditioning, it is encouraging that at the lowest PC-free dose, which is the same dose used across the RESET program with preconditioning, 50% of the patients demonstrated compelling and drug-free responses through 6 months of follow-up. PC-free rese-cel has the potential to substantially expand access for patients in current CAR T centers on an outpatient basis as well as in community-based infusion centers," said David Chang, chief medical officer.

About CABA
Cabaletta Bio, Inc. is a clinical-stage biotechnology company focused on the discovery and development of engineered T cell therapies that have the potential to provide deep and durable, perhaps curative, responses with one-time administration for patients with autoimmune diseases. Its Cabaletta Approach to B cell Ablation (CABA) platform encompasses two strategies: Chimeric Antigen Receptor T cells for Autoimmunity (CARTA) and Chimeric AutoAntibody Receptor T cells (CAART). Resecabtagene autoleucel, its lead product candidate from its CARTA platform, is a 4-1BB co-stimulatory domain-containing fully human CD19-CAR T construct designed to treat patients with a range of autoimmune diseases. Its DSG3-CAART product candidate is being evaluated for the treatment of mPV, a subtype of PV that affects the epithelium of the mucous membranes, in the Phase 1 DesCAARTes TM trial. Its MuSK-CAART product candidate is designed to treat a subset of patients with MG, targeting autoreactive B cells.

Cabaletta Bio Unveils New Clinical Data for Rese-cel in Autoimmune Diseases
- Clinical Trial Success: In the Phase 1/2 RESET-Myositis study, 83% of dermatomyositis patients met the registrational primary endpoint, with all patients maintaining their responses off immunomodulators during the latest follow-up, indicating the long-term efficacy of rese-cel and potentially laying the groundwork for future registration applications.
- Juvenile Patient Response: The first juvenile dermatomyositis patient demonstrated a moderate TIS response off immunomodulators, maintaining this response through the latest follow-up at 32 weeks, with expectations to include this in the 2H27 myositis BLA submission, potentially securing a priority review voucher.
- New Indication for Systemic Sclerosis: Systemic sclerosis has been announced as a second pivotal indication based on Phase 1/2 data, with a single-arm registrational study anticipated to initiate in 4Q26 involving approximately 25 patients, further validating the clinical application potential of rese-cel.
- Immune System Reset: The lowest dose of PC-free rese-cel achieved deep B cell depletion in one of the first two lupus patients treated, demonstrating that for most patients, a single dose of rese-cel can provide significant immune system reset effects that persist over time, potentially altering treatment strategies.
