      Background

      Patients with mutant EGFR (EGFRm) non–small cell lung cancer (NSCLC) have a limited chance of benefiting from treatment with programmed death-1 inhibitors. EGFR activation leads to overexpression of CD73 and may provide a mechanism of immune evasion. CD73 overexpression has also led to worse outcomes in multiple tumor types, including NSCLC. Recent studies demonstrated that an orthogonal therapeutic approach to cancer, such as combining tyrosine kinase inhibitors (TKIs) with immunotherapy, may result in synergistic clinical activity. Oleclumab is a human monoclonal antibody (mAb) that selectively binds to CD73 and inhibits the enzymatic production of adenosine. Adenosine exerts its immunosuppressive effects on various immune cells via the adenosine 2A receptor (A2AR). AZD4635 is a potent, selective A2AR antagonist that inhibits this signaling pathway. Osimertinib is a potent and selective inhibitor of EGFRm, including the T790M resistance mutation. We hypothesize that novel combinations of targeted and immunotherapeutic agents targeting the adenosine pathway will be well tolerated and lead to increased antitumor activity in subjects with EGFRm NSCLC.

      This is a multi-arm, open-label, multicenter, phase 1b/2 study (NCT03381274) consisting of 2 parts. In Part 1, the safety and tolerability of oleclumab in combination with either osimertinib (Arm A) or AZD4635 (Arm B) will be evaluated, and a recommended phase 2 dose for each combination will be identified. In Part 2, the safety, tolerability, and preliminary antitumor activity will be evaluated. In both parts, patients will be allocated to treatment arms based upon their EGFRm status and their prior therapy. For Part 2, the primary objective of antitumor activity will be assessed by objective response according to RECIST v1.1. Key secondary objectives include additional evaluation of clinical activity, the pharmacokinetic profiles of oleclumab, osimertinib, and AZD4635, and the evaluation of oleclumab immunogenicity. Additional treatment arms may be added as the study progresses. The study is open for enrollment and recruitment is ongoing, with a planned enrollment of up to approximately 98 patients.
