ALPN-202 induces a more potent anti-tumor T cell response in MC38/hPD-L1 tumors than PD-L1 blockade alone
Ontology highlight
ABSTRACT: Purpose: Use RNA-seq to characterize the anti-tumor immune response induced by ALPN-202 and compare to that of anti-PD-L1 treatment alone. Methods: mRNA was isolated from MC38/hPD-L1 tumors 72 hours after a single dose of ALPN-202 (n=4), anti-PD-L1 mAb (durvalumab) (n=4), or Fc control (n=4). Results: ALPN-202 treatment resulted in elevated expression of multiple T cell, NK cell, myeloid cell genes. Additionally, there was a strong increase in genes commonly associated with a proinflammatory response including cytokines, chemokines and surface markers. Conclusions: ALPN-202 treatment resulted in a strong anti-tumor immune response that was more potent than that generated by blockade of PD-L1 alone.
