A Study of NPX267 for Subjects With Solid Tumors Known to Express HHLA2/B7-H7
NPX267 is an antibody drug targeting the inhibitory receptor for B7-H7 (HHLA2) which may control evasion of the immune response in tumors. The goal of this clinical trial is to learn whether NPX267 is safe and tolerable in patients whose cancers are known to express HHLA2 including epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer. The main questions it aims to answer are: * what is an appropriate dose to be given to patients? * are the side effects of treatment manageable? Participants will be evaluated for participation in the study. Patients who are treated will receive an intravenous infusion of NPX267 every three weeks if their disease has not progressed. Patients will be closely monitored by the treating physician.

- Have any unresolved toxicity of Grade ≥ 2 from previous anti-cancer treatment, except for alopecia, chronic neuropathy \> 6 months, or changes in skin pigmentation
- Have known or suspected brain metastases, unless they are clinically stable
- Known autoimmune disease requiring immunosuppressive treatment requiring the equivalent of more than 10 mg prednisone daily
- History of grade 3 immune-related pneumonitis or colitis
