This is Phase 2, open label, multi-center study to assess safety and efficacy of vactosertib in combination with pembrolizumab as 1st line treatment for subjects with advanced or metastatic, PD-L1 positive, non-small cell lung cancer (NSCLC) who have not previously received systemic therapy for advanced disease and in whom EGFR, ALK, BRAF, ROS1-directed therapy is not indicated.

Phase 2
| Drug | Synonyms | Arms |
|---|---|---|
| Vactosertib 300 mg BID and pembrolizumab 200 mg IV | vactosertib+Pembrolizumab |
Approximately 55 NSCLC subjects with PD-L1 tumor proportion score (TPS) ≥ 1% are expected to
be enrolled in this study. Subjects' TPS will be determined by PD-L1 IHC 22C3 pharmDx assay
performed according to local laboratory regulations prior to study enrollment.
Subjects who received adjuvant or neoadjuvant therapy are permitted onto the study if the
therapy was completed at least 12 months prior to the development of metastatic disease.
Eligible subjects will receive:
• Vactosertib 300 mg orally (PO) BID for 5 days with 2 days off period (5 days on/2days off)
and pembrolizumab 200 mg IV on Day 1 of every 3-week cycle (Q3W).
