Cabaletta Bio Receives FDA Fast Track Designation for DSG3-CAART for the Treatment of Mucosal Pemphigus Vulgaris

Cabaletta Bio, Inc. (Nasdaq: CABA), a clinical-stage biotechnology company focused on the discovery and development of engineered T cell therapies for patients with B cell-mediated autoimmune diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for DSG3-CAART (Desmoglein 3 Chimeric AutoAntibody Receptor T cells), the Company’s lead product candidate for treatment of mucosal pemphigus vulgaris (mPV), for improving healing of mucosal blisters in patients with mPV.

“We believe that this Fast Track Designation, coming shortly after the Orphan Drug Designation for DSG3-CAART, further demonstrates that mPV is a devastating, rare disease for which patients have limited treatment options resulting in a large unmet need. The Fast Track Designation represents an important next step in our clinical development plans,” said David J. Chang, MD, Chief Medical Officer of Cabaletta in a press release. “We appreciate the benefits provided by this designation, including the opportunity for increased access to the FDA and potential acceleration of our clinical development path and regulatory review process.”

DSG3-CAART is designed to specifically target the cause of mPV, B cells that express pathogenic autoantibodies directed against the DSG3 protein, while preserving normal B cell immune function. The Company plans to initiate its Phase 1 DesCAARTes™ trial to evaluate the safety and tolerability of DSG3-CAART in relapsed and/or refractory patients in 2020. DSG3-CAART is based on technology licensed from and has been developed in collaboration with the University of Pennsylvania.
