About Cabaletta Bio

Cabaletta Bio (NASDAQ: CABA) is focused on the discovery and development of T cell therapies for B cell-mediated autoimmune diseases. Our proprietary technology utilizes Chimeric AutoAntibody Receptor (CAAR) T cells that are designed to precisely bind and destroy only specific autoantibody-expressing B cells while sparing normal antibody-expressing B cells, which are essential for human health. Cabaletta’s Approach for selective B cell Ablation platform, called our CABA™ platform, has applicability across more than two dozen B cell-mediated autoimmune diseases that we have identified, reviewed and prioritized. CAAR T technology is based on the revolutionary Chimeric Antigen Receptor (CAR) T cell technology developed at the University of Pennsylvania that resulted in one of the first commercially-available CAR T cell products for the treatment of B cell malignancies. Cabaletta has an exclusive global licensing agreement and multiple sponsored research agreements with the University of Pennsylvania to develop CAAR T technology to treat B cell-mediated autoimmune diseases.

The Company’s lead product candidate, DSG3-CAART, received IND clearance from the FDA in September 2019, and initial safety data in clinical trials has been reported. DSG3-CAART is designed to be a potential treatment for patients with mucosal pemphigus vulgaris (mPV), which is a rare autoimmune blistering disorder that causes painful blisters and sores on mucous membranes leading to severe and sometimes debilitating and life-altering effects. Cabaletta Bio is also pursuing additional pipeline candidates for other B cell mediated disorders including MuSK Myasthenia Gravis (MG) with an IND planned for 2H 2021, mucocutaneous PV, PLA2R positive membranous nephropathy (PMN), and Factor VIII inhibitors.

Uniquely Differentiated. Rapid. Elegant.

At Cabaletta, we are driven by the shared mission of developing a new type of therapy, where patients’ own cells are used to fight disease. We are building a culture grounded in the knowledge that success in the Cabaletta mission lies in the hands of individuals across every aspect of the company. To nurture this, we make an active commitment to the well-being and continuous growth of each person who joins our team. In this way, we are not only working to improve the lives of patients, but of everyone involved. #CabalettaCrew
