Frequently asked questions about DSG3-CAART

What is DSG3-CAART used for in Pemphigus Vulgaris?

DSG3-CAART is an investigational cell therapy being studied for the treatment of Pemphigus Vulgaris, a rare autoimmune blistering skin disease. It is designed to target and eliminate the specific immune cells that produce antibodies against desmoglein 3, a protein essential for skin cell adhesion. The drug is currently in Phase 1 clinical development.

What does DSG3-CAART target?

DSG3-CAART targets desmoglein 3, a protein involved in cell-to-cell adhesion in the skin. The therapy is engineered to recognize and destroy the autoreactive B cells that produce antibodies against desmoglein 3, which are responsible for the blistering seen in Pemphigus Vulgaris. This targeted approach aims to halt the autoimmune attack while preserving normal immune function.

Who makes DSG3-CAART?

DSG3-CAART is being developed by Cabaletta Bio, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol CABA. The company specializes in developing engineered T cell therapies for autoimmune diseases. Cabaletta Bio is conducting the clinical trials for DSG3-CAART in patients with Pemphigus Vulgaris.

What phase is DSG3-CAART in?

DSG3-CAART is currently in Phase 1 clinical development. It is an investigational therapy, meaning it has not been approved by regulatory authorities and is still being evaluated for safety and efficacy in clinical trials. The drug has received Orphan Drug and Fast Track designations from the FDA, which may expedite its development and review process.

What clinical trials is DSG3-CAART in?

DSG3-CAART is being studied in a single clinical trial with the identifier NCT04422912, known as the RESET-PV study. This is a Phase 1/2, open-label, controlled trial enrolling approximately 40 participants with active Pemphigus Vulgaris in the United States. The study is currently recruiting patients aged 18 years and older.

Is DSG3-CAART the same as CABA-201?

DSG3-CAART and CABA-201 are distinct investigational therapies, though they are both being studied in the same clinical trial for Pemphigus Vulgaris. DSG3-CAART is a chimeric autoantibody receptor T cell therapy targeting desmoglein 3, while CABA-201 is a CD19-specific chimeric antigen receptor T cell therapy. Both are being evaluated in the RESET-PV study.
