A phase 1/2, open-label, safety and dosing study of autologous CART cells (desmoglein 3 chimeric autoantibody receptor T cells \[DSG3-CAART\] or CD19-specific Chimeric Antigen Receptor T cells \[CABA-201\]) in subjects with active, pemphigus vulgaris
Pemphigus vulgaris (PV) is a B-cell mediated autoimmune disorder in which painful blisters are formed on the skin or mucosal membrane, including the mouth, nose, throat, eyelids, anus, and genitals. This phase 1/2 study is being conducted in two parts. The first part is the main study conducted to find the maximum tolerated dose and optimal fractionated infusion schedule of an investigational cell therapy, DSG3-CAART, that can be given to patients with mucosal PV who are inadequately managed by standard therapies. This study is closed to enrollment. The second part is a sub-study is being co…
Inclusion Criteria for DSG3-CAART: Closed to enrollment * Confirmed diagnosis of mPV by prior or screening biopsy and prior positive anti- DSG3 antibody ELISA * mPV inadequately managed by at least one standard immunosuppressive therapies * Active mPV at screening * Anti-DSG3 antibody ELISA positive at screening Inclusion Criteria for CABA-201 sub-study: Open to enrollment * Age ≥18 * Confirmed diagnosis of PV by prior or screening biopsy and prior positive DSG3 ELISA, IIF, and/or DIF * PV inadequately managed by at least one standard immunosuppressive therapy * Active PV at screening * DSG…
Intravenous infusions of DSG3-CAART alone at different doses and different fractionations, with or without intravenous immunoglobulin, cyclophosphamide, and/or fludarabine.
Single intravenous infusion of CABA-201 at escalating doses, with or without preconditioning.
