Phase 2 Study to Evaluate Reduced Dose Chemotherapy in Combination With Anti-PD-1 Therapy as First Line Treatment in Vulnerable or Older Adults (Vulnerable or Age ≥70) With Advanced PD-L1 TPS <50% Non-small Cell Lung Cancer
Evaluate frequency of adverse events that lead to chemotherapy discontinuation in vulnerable older adults with recurrent/metastatic PD-L1 TPS\<50% NSCLC patients who receive reduced dose chemotherapy in combination with immunotherapy.
