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, an autoimmune blistering skin condition. It is designed to target and eliminate the specific immune cells that produce antibodies against desmoglein 3, a protein involved in skin cell adhesion, potentially reducing disease activity.

What does DSG3-CAART target?

DSG3-CAART targets DSG3, which is desmoglein 3, a protein found on the surface of skin cells. The therapy is engineered to recognize and attack the B cells that produce autoantibodies against DSG3, which are responsible for the blistering seen in Pemphigus Vulgaris.

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 is focused on developing targeted cellular therapies for autoimmune diseases.

What phase is DSG3-CAART in?

DSG3-CAART is currently in Phase 1 clinical development. It is an investigational therapy and has not been approved by the FDA. The drug has received Orphan Drug and Fast Track designations from the FDA, which are intended to expedite its development and review.

What clinical trials is DSG3-CAART in?

DSG3-CAART is being evaluated in a Phase 1/2 clinical trial with the identifier NCT04422912, known as the RESET-PV study. This open-label, controlled trial is recruiting approximately 40 participants with active Pemphigus Vulgaris in the United States. The study is not randomized or double-blinded.

Is DSG3-CAART the same as CABA-201?

DSG3-CAART is not the same as CABA-201. The RESET-PV trial is studying two separate investigational cell therapies: DSG3-CAART, which targets desmoglein 3, and CABA-201, which targets CD19. Both are being tested in patients with Pemphigus Vulgaris, but they have different molecular targets.
