Study to Evaluate Monotherapy and Combination Immunotherapies in Participants With PD-L1 Positive Non-small Cell Lung Cancer

Official Title

A Phase 2 Study to Evaluate the Safety and Efficacy of AB122 Monotherapy, AB154 in Combination With AB122, and AB154 in Combination With AB122 and AB928 in Front-Line, Non-Small Cell Lung Cancer


This randomized phase 2 open-label study will evaluate the safety and efficacy of zimberelimab (AB122) monotherapy, domvanalimab (AB154) in combination with zimberelimab, and domvanalimab in combination with zimberelimab and etrumadenant (AB928) in front-line, PD-L1 positive, metastatic non-small cell lung cancer.

Trial Description

Primary Outcome:

  • Objective response rate (ORR)
  • Progression-free survival (PFS)
Secondary Outcome:
  • Duration of response (DoR)
  • Disease control rate (DCR)
  • Adverse Events
  • Pharmacodynamics of zimberelimab
  • Pharmacodynamics of domvanalimab
  • Pharmacodynamics of etrumadenant
  • Immunogenicity of zimberelimab
  • Immunogenicity of domvanalimab
This is an open-label phase 2 study in participants with non-small cell lung cancer which will assess the safety, efficacy and tolerability of zimberelimab as monotherapy and in combination with other immunotherapeutics across multiple treatment arms.

Approximately 150 participants will be randomized to 1 of 3 treatment arms: 1) zimberelimab, 2) zimberelimab + domvanalimab (anti-TIGIT antibody), 3) zimberelimab + domvanalimab + etrumadenant (dual adenosine receptor antagonist). Participants that progress on the zimberelimab monotherapy arm may cross-over to receive the third arm combination of zimberelimab + domvanalimab + etrumadenant.

The primary objective of this clinical study is to evaluate the efficacy of each combination therapy by assessing: 1) objective response rate (ORR) of participants with measurable disease by Response Evaluation Criteria in Solid Tumours (RECIST v1.1) and 2) progression free survival (PFS).
