(A) Treatment timeline for patient with chemotherapy refractory PDAC prior to initiation of Trametinib, Ruxolitinib, and Nivolumab treatment. Pre-treatment (B) and post-treatment (C) PET/CT scan showing a significant reduction in size and FDG avidity of both locally recurrent tumor in pancreatic bed (white arrows) and in a segment VII liver metastasis (yellow arrows) on PET/CT imaging following 3 months of treatment with Trametinib, Ruxolitinib, and Nivolumab; (D) Design of Phase 1 clinical trial investigating Trametinib (MEKi), Ruxolitinib (STAT3i), and Retifanlimab (αPD-1) in advanced/metastatic pancreatic cancer patients. Proposed treatment schedules, as well as scheme for biopsies/blood collection for correlative endpoints, are shown.
