Durvalumab in A375 and HPAC human tumour xenografts with human CD4+/CD8+ T cells; HPAC max tumour growth inhibition 74%
“The Applicant used A375 (human melanoma) and HPAC (human pancreatic adenocarcinoma) cells enriched for CD4+ and CD8+ T cells. Treatment with durvalumab reduced the tumour volume in the HPAC xenograft model, resulting in a maximum tumour growth inhibition of 74%.”
Binds only human and cynomolgus monkey PD-L1; no rodent cross-reactivity for in vivo models with durvalumab
“Durvalumab was found to only bind to human and cynomolgus monkey PD-L1, and the cynomolgus monkey was found to be the only relevant nonclinical species for the safety and toxicity studies.”
