14P Anti-PDL1/IL-15 fusion protein increases rare effector cells in cynomolgus monkeys and mice

ConclusionKD033 administration increases CD8+ T and NK cells, consistent with IL-15 pharmacodynamics. In addition, analysis of peripheral blood from KD033 surrogate best and non-responder mice demonstrated increases in different immune populations, which can facilitate their use as in-treatment biomarkers of KD033 activity in tumors. Importantly, KD033 administration resulted in increases in rare cytotoxic cells such as NKT and gamma delta T cells in peripheral blood which may contribute to its anti-tumor activity and immunity.Legal entity responsible for the studyKadmon Corporation LLC.FundingKadmon Corporation LLC.DisclosureS.
