This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

tislelizumab-jsgr. A monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed cell death 1 (PD-1), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, tislelizumab-jsgr binds to PD-1 and inhibits the binding of PD-1 to the PD-1 ligands programmed cell death-1 ligand 1 (PD-L1), and PD-1 ligand 2 (PD-L2). This prevents the activation of PD-1 and its downstream signaling pathways. This may restore immune function through the activation of both T cells and T-cell-mediated immune responses against tumor cells. PD-1, a transmembrane protein in the immunoglobulin (Ig) superfamily expressed on activated T cells, negatively regulates T-cell activation and effector function when activated by its ligands; it plays an important role in tumor evasion from host immunity.

Cxcr1/2 inhibitor SX-682. An orally bioavailable, selective and reversible antagonist of C-X-C motif chemokine receptors 1 (CXCR1) and 2 (CXCR2), with potential anti-inflammatory and antineoplastic activities. Upon administration CXCR1/2 inhibitor SX-682 selectively and allosterically binds to CXCR 1 and 2 and inhibits their activation by tumor-secreted chemokines. This inhibits CXCR1/2-mediated signaling, reduces both recruitment and migration of immunosuppressive myeloid-derived suppressor cells (MDSCs) and neutrophils in the tumor microenvironment (TME), inhibits inflammatory processes and abrogates the immunosuppressive-induced nature of the TME. This allows effector cells, such as natural killer (NK) cells and cytotoxic T lymphocytes (CTLs), to kill and eliminate cancer cells. This inhibits tumor cell migration, metastasis, angiogenesis and tumor cell proliferation. CXCR1 and 2, G protein-coupled receptor proteins located on myeloid cells and certain tumor cells, play key roles in the immunosuppressive nature of the TME, tumor metastasis, therapy-resistance and myeloid cell suppression. They play a key role in inflammation and their expression is elevated in several inflammatory-driven diseases. NCI Drug Dictionary

Treatments listed in the registry

• Tislelizumab (Drug): Patients will receive Tislelizumab (200 mg intravenous) on Day 1 of Cycles 1-6. Cycle 1 will be 14 days long and occur prior to surgery. Cycle 2 will be 14 days long and occur prior to standard of care chemotherapy. Cycles 3-6 will each be 21 days long and will be given after completion of standard of care chemotherapy.
• SX-682 (Drug): Patients will receive SX-682 (200 mg twice daily by mouth) on Days 1-14 of Cycles 1-2 and Days 1-21 of Cycles 3-6. Cycle 1 will be 14 days long and occur prior to surgery. Cycle 2 will be 14 days long and occur prior to standard of care chemotherapy. Cycles 3-6 will each be 21 days long and will be given after completion of standard of care chemotherapy.
