Grapiprant (ARY-007) and Pembrolizumab in Patients With Advanced or Metastatic Post-PD-1/L1 NSCLC Adenocarcinoma

Phase 1
Terminated
Conditions
Non-small Cell Lung Cancer Adenocarcinoma
Interventions
Registration Number
NCT03696212
Lead Sponsor
Arrys Therapeutics
Brief Summary

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.
