Brief Summary:

The purpose of this study is to assess the safety, tolerability, and clinical activity of KYV 101 (a fully-human anti-CD19 CAR T-cell therapy) in adult subjects with B cell-driven autoimmune diseases. The trial anticipates enrolling participants to reach a maximum of 24 participants who will receive 1 dose of KYV-101 and will be followed for 2 years.

PHASE1

Detailed Description:

The purpose of this study is to assess the safety, tolerability, and clinical activity of KYV 101 (a fully-human anti-CD19 CAR T-cell therapy) in 24 adult subjects with B cell-driven autoimmune diseases. The diseases under study include: idiopathic necrotizing myopathy (INM) consisting of dermatomyositis (DM), necrotizing myopathy, anti-HMGCoA-associated myopathy, and polymyositis (PM), diffuse cutaneous systemic sclerosis (dcSSc), systemic lupus erythematosus (SLE) with nephritis, and ANCA-associated vasculitis (AAV). Six participants in each autoimmune disease group for a total of 24 participants will receive a single dose of 1.0×10\[8\] CAR+ T cells. Participants will be followed under this protocol for 2 years. Lymphodepleting chemotherapy of cyclophosphamide (CYC) 300 mg/m2 and fludarabine (FLU) 30 mg/m2 intravenously (IV) daily for 3 days will be administered 5 to 7 days prior to administration of KYV-101.
