ABBV-514 / AbbVie - LARVOL DELTA

CCR8-targeted Treg depletion and PD-1 blockade combine to divert CD8+ T cells from exhaustion associated transcriptional trajectories within the tumor microenvironment (SITC 2024) - P1 | "A human CCR8 specific afucosylated IgG1 antibody (ABBV-514) is currently being evaluated in a Phase I clinical trial both as monotherapy and in combination with budigalimab, a PD-1-blocking antibody (NCT05005403). All animal studies were reviewed and approved by AbbVie's Institutional Animal Care and Use Committee or Oversight Body (in accordance with national regulations). Animal studies were conducted under an AAALAC accredited program, where veterinary care and oversight was provided to ensure optimal animal care."
