1. An isolated antibody, or an antigen-binding fragment thereof, comprising:
- a) a heavy chain CDR sequence selected from the group consisting of SEQ ID NOs;
7-9;
orb) a light chain CDR sequence selected from the group consisting of SEQ ID NOs;
10-12,wherein the isolated antibody, or an antigen-binding fragment thereof, binds to a PD-1 protein having the amino acid sequence of SEQ ID NO;
2, and the isolated antibody, or antigen-binding fragment thereof, is chimeric, humanized, composite, or human.

Abstract
The present invention is based, in part, on the identification of novel human anti-PD-1, PD-L1, and PD-L2 antibodies. Accordingly, the invention relates to compositions and methods for diagnosing, prognosing, and treating conditions that would benefit from modulating PD-1, PD-L1, and/or PD-L2 activity (e.g., persistent infectious diseases, autoimmune diseases, asthma, transplant rejection, inflammatory disorders and tumors) using the novel human anti-PD-1, PD-L1, and PD-L2 antibodies described herein.
