Open Label, Single Arm, Phase 1b/2 Study to Evaluate the Safety and Efficacy of Grapiprant (ARY-007) in Combination With Pembrolizumab in Patients With Advanced or Metastatic Post-PD-1/L1 Non-Small Cell Lung Cancer (NSCLC) Adenocarcinoma

简要总结
This study will be conducted in adult participants diagnosed with NSCLC who have been previously treated for a minimum of 12 weeks with any PD-1 or PD-L1 checkpoint inhibitor. This is a phase 1b/2, multi-center, open label study designed to assess safety and tolerability of grapiprant in combination with pembrolizumab, to determine the recommended phase 2 dose (RP2D) with pembrolizumab, and to evaluate disease response with grapiprant based on investigator assessments. Pharmacokinetics, pharmacodynamics and response biomarkers will also be assessed.
