Study of KYV-101 Anti-CD19 CAR T Therapy in Adult Dermatomyositis

Dermatomyositis Clinical Trial

Official title: Phase 1B, Open-Label Study of KYV-101, an Autologous Fully-Human Anti-CD19 Chimeric Antigen Receptor T-Cell (CD19 CAR T) Therapy, in Adult Patients With Treatment Refractory Dermatomyositis

Status Not yet recruiting

Clinical Trial Summary

The goal of this clinical trial is to characterize to understand the effects of a type of cell therapy called Chimeric Antigen Receptor T lymphocyte (CAR T) therapy in adult patients with the autoimmune disease dermatomyositis. This study will utilize a technology that modifies a type of white blood cell called the cytotoxic T lymphocyte-this T cell normally functions in the immune system to kill infected or potentially harmful cells in the body. In CAR T therapy, the patients' white blood cells are harvested and the cytotoxic T cells are isolated and modified such that they are programmed to kill any cell that has a protein structure called "CD19" on its outer surface (membrane). Since the CD19 protein is only present on a type of white blood cell called the B lymphocyte, when these "re-engineered" cytotoxic T lymphocytes are then given back to the patient (by an infusion), these cells will seek out and kill essentially all of the patient's B cells. B cells are an important part of a person's immune system and have many functions, including the production of antibodies. It is thought that, in dermatomyositis and other autoimmune diseases, a tiny subset of these B cells plays a large role in making autoantibodies (antibodies directed against the patient's own tissues) and causing disease. The idea is that the therapy will "wipe out" all/most of the B cells in the patient so that they can make an entirely new set of B cells to recreate a functional immune system without the autoimmune disease.

The main questions the study intends to answer are:

• Understanding how well patients tolerate undergoing this therapy in terms of side effects;

• Getting an early idea if this therapy can help certain aspects of the autoimmune disease, including inflammation in the skin, muscles, and lungs;
