NC318 Alone or in Combination with Pembrolizumab for the Treatment of Locally Advanced or Metastatic Non-small Cell Lung Cancer
This phase II trial tests how well NC318 works alone or in combination with pembrolizumab in treating patients with non-small cell lung cancer (NSCLC) that has spread to nearby tissue or lymph nodes (locally advanced) or has spread from where it first started (primary site) to other places in the body (metastatic). NC318 is an investigational drug that relieves immune suppression in tumors by blocking a protein called siglec15 expressed in the tumor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. NC318 may help restore anti-tumor immunity in patients whose lung cancer has progressed on prior immunotherapy with anti-PD-1 axis therapy, leading to tumor response and better outcomes. In patients who have yet to receive immunotherapy with anti-PD-1 axis therapy, the addition of NC318 to standard treatment with pembrolizumab could also help improve outcomes.
