  • Publication number: 20220363770
    Abstract: The present invention relates to antagonist antibodies of the human calcitonin gene-related peptide (CGRP) receptor as well as bispecific antigen binding proteins derived from the anti-CGRP antibodies that bind to and inhibit both the human CGRP receptor and another target, such as the human pituitary adenylate cyclase activating polypeptide type I receptor (PAC1) receptor. Pharmaceutical compositions comprising the anti-CGRP receptor antibodies and bispecific antigen binding proteins as well as methods for producing them are also disclosed. Methods of using the anti-CGRP receptor antibodies and bispecific antigen binding proteins to ameliorate, treat, or prevent conditions associated with the CGRP and PAC1 receptors, such as chronic pain, migraine, and cluster headache, are also described.

  • Publication number: 20220204611
    Abstract: The present invention relates to antigen binding proteins, such as monoclonal antibodies, that specifically bind to and activate human triggering receptor expressed on myeloid cells-2 (TREM2) and pharmaceutical compositions comprising such antigen binding proteins. The agonist antigen binding proteins (e.g. antibodies) of the invention are capable of activating TREM2/DAP12 signaling in myeloid cells in the absence of Fc-mediated cross-linking of the antigen binding proteins. Methods of treating or preventing conditions associated with TREM2 loss of function, such as Alzheimer's disease and multiple sclerosis, using the antigen binding proteins are also described.
