This phase II trial tests whether CXCR1/2 inhibitor SX-682 (SX-682) with pembrolizumab works to treat patients with stage IIIC or IV non-small cell lung cancer that has spread to other parts of the body (metastatic) or that has come back (recurrent). SX-682 is a drug that binds to receptors on some types of immune and cancer cells, inhibiting signaling pathways, reducing inflammation, and allowing other types of immune cells to kill and eliminate cancer cells. Pembrolizumab is a monoclonal antibody that binds to a receptor called PD-1 that is found on the surface of T-cells (a type of immune cell), activating an immune response against tumor cells. Giving SX-682 in combination with pembrolizumab may be more effective at treating patients with metastatic or recurrent non-small cell lung cancer than giving these treatments alone.
Subjects aged 18 years and older
Pathologically or cytologically confirmed non-small cell lung cancer with no known oncogenic EGFR mutation, ALK rearrangement, ROS1 rearrangement or RET rearrangement
Tumoral PD-L1 expression >=1% by any Clinical Laboratory Improvement Act (CLIA)-certified assay
Metastatic or recurrent non-small cell lung cancer (NSCLC). Stage IIIC per 8th edition TNM stage classification is allowed if not amenable to curative surgery or radiation per investigator judgment
Participants may have received prior chemotherapy, immune checkpoint inhibitor, and/or immune modulatory therapy in the curative setting if the last dose of treatment was more than (>) 24 weeks prior to consenting
For patients with NSCLC harboring an oncogenic alteration other than listed may have received prior small molecule inhibitor therapy (e.g. MET inhibitor for MET exon 14 mutated NSCLC). A wash-out period of at least 5 half-lives is required prior to start of study treatment
Presence of other active cancers within the last 2 years. Patients with any prior early stage cancer who have received definitive local treatment at least 2 years previously and no evidence of recurrence are eligible. All patients with previously treated in situ carcinoma are eligible, as patients with history of non-melanoma skin cancer
Symptomatic central nervous system (CNS) metastases; participants with known brain metastasis must be asymptomatic with no steroids or escalating doses of antiepileptics within 7 days prior to start of study treatment
