Executive Summary
ARZERRA (ofatumumab), developed by Novartis, is a monoclonal antibody targeting CD20-positive B-cells, approved primarily for chronic lymphocytic leukemia (CLL) and, more recently, for multiple sclerosis (MS). Its market trajectory is shaped by factors including evolving clinical indications, competitive landscape, regulatory developments, and pricing strategies. This report examines ARZERRA's current market position, growth drivers, challenges, and future financial outlook, providing actionable insights for stakeholders.
What Is ARZERRA and How Does Its Mechanism of Action Influence Its Market?
ARZERRA (ofatumumab) is a fully human monoclonal antibody that binds to a unique, membrane-proximal epitope on CD20. Its mechanism involves complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC). This mode of action offers advantages in targeting malignant B-cells and has spurred development across hematologic and autoimmune indications.
