Director/Sr. Director of Regulatory Affairs

Philadelphia, PA

Cabaletta Bio is focused on the discovery and development of T cell therapies for B cell-mediated autoimmune diseases. Cabaletta’s therapeutic platform produces highly selective autologous Chimeric AutoAntibody Receptor (CAAR) T cells that are designed to precisely bind and destroy only specific autoantibody-producing B cells while sparing normal antibody-producing B cells, which are essential for human health. The platform 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 the CAAR T technology to treat B cell-mediated autoimmune diseases. The Company’s lead therapeutic program is a potential treatment for a prototypical B cell-mediated autoimmune disease, mucosal pemphigus vulgaris (mPV), which is a rare skin disorder that causes painful blisters and sores on mucous membranes leading to severe and sometimes debilitating and life-altering effects.

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

Our name – Cabaletta – is derived from the operatic term for the second part of an aria that is designed to highlight the technical expertise of the lead singer. While our company is not the first to develop chimeric T cells as therapies, we are the first to develop them in a way that leverages T cells to specifically eliminate only B cells that cause disease, while sparing healthy B cells. Utilizing the backbone of this core technology, we expect to advance our portfolio with a rapid and repetitive rhythm, similar to the rhythm that is typical of a cabaletta.
