First-in-Human Study of BAT4406F, an ADCC-Enhanced Fully Humanized Anti-CD20 Monoclonal Antibody in Patients With Neuromyelitis Optica Spectrum Disorders.

ABSTRACT:

Introduction

Neuromyelitis optica spectrum disorder (NMOSD) is a rare debilitating autoimmune disease of the central nervous system (CNS). This is the first-in-human dose-escalation Phase I clinical study of BAT4406F, an antibody-dependent cell-mediated cytotoxicity (ADCC)-enhanced fully humanized anti-CD20 monoclonal antibody, in Chinese NMOSD patients.

Patients and methods

Using a "3 + 3" design and based on the planned algorithm of dose escalation, the enrolled NMOSD patients were sequentially assigned to one of the five dose-escalation cohorts of BAT4406F with a single intravenous dose, and were then followed for a 6-month observation period. The maximum tolerated dose (MTD) and dose-limiting toxicity (DLT), safety, pharmacokinetics (PK), pharmacodynamics, and immunogeni
