“Patients diagnosed with systemic sclerosis, a rare and life-threatening chronic autoimmune disease characterized by progressive skin and internal organ fibrosis, face limited treatment options as current therapies provide only modest effects and focus on treating the complications associated with the disease. With an average patient survival of 12 years following diagnosis, there is a significant unmet need for new treatment options that focus on eliminating the root cause of the disease to prevent further organ damage for patients,” said
The FDA grants Orphan Drug Designation to drugs or biologics intended to treat or prevent rare diseases or conditions that affect fewer than 200,000 individuals in
About the RESET-SSc™ Trial
The RESET-SSc™ trial is a Phase 1/2 open-label study of CABA-201 in subjects with SSc across two parallel cohorts. The severe skin cohort will include six patients with severe skin involvement, and the organ cohort will include six patients who meet the pulmonary, cardiac, or renal involvement criteria regardless of skin involvement. Subjects will receive a one-time infusion of CABA-201 at a dose of 1 x 106 cells/kg, preceded by a standard preconditioning regimen of fludarabine and cyclophosphamide. Key inclusion criteria include patients between ages 18 and 70 (inclusive), evidence of significant skin, pulmonary, renal, or cardiac involvement, and significant organ involvement despite use of immunosuppressants. Key exclusion criteria include a primary diagnosis of another rheumatic autoimmune disease, treatment with a B cell depleting agent within six months or treatment with a biologic agent within three months. As part of Cabaletta’s CARTA (Chimeric Antigen Receptor T cells for Autoimmunity) strategy, this trial is intended to evaluate the potential ability of CABA-201 to transiently, but fully, eliminate B cells, potentially enabling durable remissions via a “reset” of the immune system.
About CABA-201
CABA-201 is designed to deeply and transiently deplete CD19-positive B cells following a one-time infusion, which may enable an “immune system reset” with the potential for durable remission off therapy in patients with autoimmune diseases. To date, Cabaletta has received clearance from the FDA for Investigational New Drug (IND) applications for CABA-201 in multiple autoimmune conditions including systemic lupus erythematosus (SLE), myositis, systemic sclerosis (SSc) and generalized myasthenia gravis (gMG). Cabaletta is conducting four RESET™ Phase 1/2 clinical trials with a total of nine cohorts that can advance simultaneously, employing a similar parallel cohort design and starting dose of 1 x 106 cells/kg without a dose escalation requirement.
About Systemic Sclerosis
Systemic sclerosis (SSc) is a rare and potentially fatal chronic autoimmune disease characterized by progressive skin and internal organ fibrosis that can be life-threatening, including interstitial lung disease, pulmonary hypertension, and scleroderma renal crisis. Although the etiology of SSc is not well understood, the pathogenic role of autoantibodies and B cells in SSc provides a rationale for studying CAR T therapy in this population. SSc affects approximately 88,000 patients in the

Forward-Looking Statements
This press release contains “forward-looking statements” of
Any forward-looking statements in this press release are based on management’s current expectations and beliefs of future events, and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: risks related to regulatory filings and potential clearance; the risk that signs of biologic activity or persistence may not inform long-term results; Cabaletta’s ability to demonstrate sufficient evidence of safety, efficacy and tolerability in its preclinical studies and clinical trials of CABA-201; the risk that the results observed with the similarly-designed construct employed in the recent academic publications, including due to the dosing regimen, are not indicative of the results we seek to achieve with CABA-201; risks related to clinical trial site activation or enrollment rates that are lower than expected; risks related to unexpected safety or efficacy data observed during clinical studies; risks related to volatile market and economic conditions and public health crises; Cabaletta’s ability to retain and recognize the intended incentives conferred by Orphan Drug Designation and Fast Track Designation for its product candidates, as applicable; risks related to Cabaletta’s ability to protect and maintain its intellectual property position; risks related to fostering and maintaining successful relationships with Cabaletta’s collaboration and manufacturing partners; uncertainties related to the initiation and conduct of studies and other development requirements for its product candidates; the risk that any one or more of Cabaletta’s product candidates will not be successfully developed and/or commercialized; and the risk that the initial or interim results of preclinical studies or clinical studies will not be predictive of future results in connection with future studies. For a discussion of these and other risks and uncertainties, and other important factors, any of which could cause Cabaletta’s actual results to differ from those contained in the forward-looking statements, see the section entitled “Risk Factors” in Cabaletta’s most recent annual report on Form 10-K as well as discussions of potential risks, uncertainties, and other important factors in Cabaletta’s other filings with the
