PHILADELPHIA, Nov. 14, 2024 – Cabaletta Bio, Inc. (Nasdaq: CABA), a clinical-stage biotechnology company focused on developing and launching the first curative targeted cell therapies designed specifically for patients with autoimmune diseases, today reported financial results for the third quarter ended September 30, 2024, and provided a business update.

 

“Focused clinical execution has resulted in 40 U.S. clinical sites actively recruiting patients for the RESET clinical trial program for CABA-201. At the ACR Convergence conference this coming weekend, we are looking forward to sharing clinical safety and efficacy data from the first 8 myositis, lupus and scleroderma patients in the RESET clinical trial program evaluating whether a single dose of CABA-201 can provide compelling clinical responses without the need for immunosuppressants,” said Steven Nichtberger, M.D., Chief Executive Officer of Cabaletta. “We are encouraged by the accelerating pace of enrollment and, data permitting, anticipate meeting with the FDA next year regarding registrational program designs for CABA-201. As we expand our clinical trial network beyond the U.S., we are pleased to welcome Gerwin Winter as Head of International for Cabaletta. Gerwin was most recently head of Europe for Beigene from inception through commercialization leveraging his prior experiences at Portola, Celgene and BMS. His team is already well positioned to leverage the recent EMA CTA authorization for the RESET-SLE trial. We look forward to expanding the opportunity for CABA-201 globally as we seek to develop and launch the first targeted curative cell therapies for patients with autoimmune diseases.”

 

Recent Operational Highlights and Upcoming Anticipated Milestones

 

CABA-201: Autologous, engineered T cells designed with a chimeric antigen receptor containing a fully human CD19 binder and a 4-1BB co-stimulatory domain as a potential

treatment for a broad range of autoimmune diseases where B cells contribute to the initiation and/or maintenance of disease.

 

Rheumatology Portfolio

 

•
Myositis (idiopathic inflammatory myopathies, IIM)
o
Patient enrollment in the RESET-Myositis trial is ongoing and additional clinical and translational data from the trial will be presented at the American College of Rheumatology (ACR) Convergence 2024 conference this coming weekend.

 

•
Systemic lupus erythematosus (SLE)
o
In October 2024, the European Medicines Agency (EMA) allowed a Clinical Trial Application (CTA) submitted by Cabaletta for the RESET-SLE trial to proceed, enabling the Company to begin the process of activating clinical trial sites and pursuing patient enrollment for the RESET-SLE trial.
o
Patient enrollment in the RESET-SLE trial is ongoing and additional clinical and translational data from the trial will be presented at ACR Convergence 2024 this coming weekend.

 

•
Systemic sclerosis (SSc)
o
Patient enrollment in the RESET-SSc trial is ongoing and initial clinical data from the trial will be presented at ACR Convergence 2024 this coming weekend.

 

Neurology Portfolio

 

•
Generalized myasthenia gravis (gMG)
o
Patient enrollment in the RESET-MG™ trial is ongoing and initial clinical data from the trial are expected in the first half of 2025.

 

Dermatology Portfolio

 

•
Pemphigus vulgaris (PV)
o
Patient enrollment is ongoing in the RESET-PV™ trial, formerly referred to as the DesCAARTes™ trial. The trial is evaluating CABA-201 as a monotherapy without preconditioning in patients with mucosal PV (mPV) and mucocutaneous PV (mcPV).

 

External Scientific Presentations and Publications

 

•
In October 2024, Cabaletta presented multiple oral and poster presentations at the European Society of Gene and Cell Therapy (ESGCT) 31st Annual Congress, which was held at La Nuvola in Rome, Italy from October 22-25, 2024. Details of the presentations and their associated key findings are below:
o
Oral presentation (OR022): Correlative findings following DSG3-CAART infusion with and without preconditioning in patients with pemphigus vulgaris (DesCAARTes™ trial). The data showed that the use of preconditioning with DSG3-CAART did not provide serologic or clinical improvement and did not deeply deplete B-cell levels in patients with mPV.
o
Poster presentation (P0744): Clinical and translational findings following MuSK-CAART infusion without preconditioning in patients with MuSK-associated
myasthenia gravis (MuSCAARTes™ trial) in the first two cohorts. The data indicated MuSK-CAART cells demonstrated evidence of biologic and clinical activity in treated patients, suggesting it may be possible to achieve clinical activity with CAR T cells in patients with autoimmune disease without preconditioning. The MusCAARTes™ trial is not currently dosing patients as we evaluate clinical and translational data from the first two cohorts.
o
Poster presentation (P0824): At-scale autologous CD19-CAR T manufacturing from whole blood collection for the treatment of autoimmune disease: process and product quality assessment. The data demonstrated large scale runs using 200mL whole blood collections yielded similar amounts of CD19-CAR T cells as runs using leukapheresis material and demonstrated similar cytotoxicity across a

range of effector to target ratios.

 

•
In November 2024, Cabaletta plans to present new and updated clinical and translational data on CABA-201 in oral and poster presentations at the ACR Convergence 2024 conference, which is being held at the Walter E. Washington Convention Center in Washington, D.C. from November 14-19, 2024.

About CABA-201

CABA-201 is a 4-1BB-containing fully human CD19-CAR T cell investigational therapy for patients with autoimmune diseases where B cells contribute to the initiation and/or maintenance of disease. Following a one-time infusion, CABA-201 is designed to transiently and completely deplete all CD19-positive cells. We believe this approach has the potential to reset the immune system and result in compelling clinical responses without chronic therapy requirements in patients. Cabaletta is currently evaluating CABA-201 in the RESET™ (REstoring SElf-Tolerance) clinical development program which includes multiple disease-specific, company-sponsored clinical trials across growing portfolios of autoimmune diseases in a broad range of therapeutic areas, including rheumatology, neurology and dermatology.
