Publication number: 20220363770Abstract: 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.Type: ApplicationFiled: June 26, 2020Publication date: November 17, 2022Applicant: AMGEN INC.Inventors: Irwin CHEN, Su CHONG, Fernando GARCES, Mark Leo MICHAELS, Christopher MOHR, Kenneth William WALKER, Zhulun WANG, Neeraj Jagdish AGRAWAL, Bryna FUCHSLOCHER, Kevin GRAHAM, Agnes Eva HAMBURGER, Derek E.

Publication number: 20220204611Abstract: 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.Type: ApplicationFiled: September 28, 2021Publication date: June 30, 2022Inventors: Ian N. FOLTZ, Shilpa SAMBASHIVAN, Irwin CHEN, Susie Miki HARRIS, Dora TOLEDO WARSHAVIAK, Ian DRIVER, Daniel LU
