Abstract

Provided herein are compositions and related methods for delivering an IgG-decoy receptor to the CNS. The methods include systemic administration of a bifunctional decoy receptor-BBB receptor antibody fusion antibody comprising a receptor extracellular domain (ECD) covalently linked to an antibody to a receptor expressed on the surface of the blood-brain barrier (BBB receptor). In some embodiments, the compositions described herein are administered to treat a subject suffering from a CNS condition.

Claims

1. A HIRMAb-TNFR bifunctional decoy receptor fusion antibody comprising two fusion heavy chains of SEQ ID NO:

4, and two light chains of SEQ ID NO;

6.
