Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 conducted to investigate if CABA-201, also called resecabtagene autoleucel, or "rese-cel", can be safely administered while achieving clinical responses without the need for preconditioning in mucosal-dominant PV (mPV) and mucocutaneous PV (mcPV) patients. This sub-study is open to enrollment.

DSG3-CAART or CABA-201 may potentially lead to complete and durable remission of disease.
