Study TitleSimultaneous targeting of PD-1 and IL2Rβγ with radiation therapy to inhibit pancreatic cancer growth and metastasis - mouse blood T-cell metabolomics
Study SummaryMice were orthotopically implanted with PK5L1940 cells then radiation therapy (8 Gy) administered 7 days post-implantation. PD1-IL2v and aCD25 dosed once per week beginning day 7 post-implantation. Blood was collected at time of sacrifice and sorted for CD8+ T-cells. The obtained T-cells were profiled by mass spectrometry-based metabolomics.

Project Title:Simultaneous targeting of PD-1 and IL2Rβγ with radiation therapy to inhibit pancreatic cancer growth and metastasis
Project Summary:In pancreatic ductal adenocarcinoma (PDAC) patients, we show that response to radiation therapy (RT) is characterized by increased IL2Rβ and IL2Rγ and decreased ILR2α expression. The bispecific aPD1-IL2v is a PD-1-targeted IL-2 variant (IL2v) immunocytokine with engineered IL-2 cis-targeted to PD-1 and abolished IL2Rα binding, which enhances tumor-antigen specific T cell activation while reducing regulatory T cell (Treg) suppression. Using aPD1-IL2v in orthotopic PDAC KPC-driven tumor models, we show marked improvement in local and metastatic survival along with profound increase in tumor-infiltrating polyfunctional CD8+ T cell subsets with a transcriptionally and metabolically active phenotype, and preferential activation of antigen-specific CD8+ T cells. In combination with single dose RT, aPD1-IL2v treatment results in a robust, durable expansion of polyfunctional CD8+ T cells, T cell stemness, tumor-specific memory immune response, natural killer (NK) cell activation, and decreased Tregs. These data show that aPD1-IL2v leads to profound local and distant response in PDAC.
