Cabaletta Bio, Inc.

Cabaletta Bio, Inc. is a biotechnology firm in the clinical development stage, specializing in the invention and advancement of sophisticated engineered T cell therapies.

Its core mission is to treat autoimmune diseases where B cells are implicated in producing harmful autoantibodies.

The company's unique chimeric autoantibody receptor (CAAR) T cell platform is engineered to precisely target and eradicate these specific disease-causing B cells. Leading its pipeline is DSG3-CAART, which is currently in Phase I clinical trials. This candidate is being assessed for efficacy in two distinct conditions: mucosal pemphigus vulgaris, an autoimmune blistering skin disorder, and Hemophilia A in patients exhibiting Factor VIII alloantibodies. Cabaletta's broader product candidate portfolio also includes MuSK-CAART, a preclinical asset aimed at a particular subset of myasthenia gravis patients; FVIII-CAART, in the discovery phase for another subgroup of Hemophilia A sufferers; and DSG3/1-CAART, also a discovery-stage program, designed for mucocutaneous pemphigus vulgaris.

The company maintains strategic alliances, including a collaboration with the University of Pennsylvania and a research pact with The Regents of the University of California. Founded in 2017 as Tycho Therapeutics, Inc., it adopted the name Cabaletta Bio, Inc. in August 2018 and is based in Philadelphia, Pennsylvania.
