Relapse is defined as disease progression after last regimen; refractory is defined as intolerable or progressing disease (PD), or stable disease (SD) to the last regimen.
For phase IIa part, subjects with histologically confirmed diagnosis of unresectable local advanced or metastatic TNBC, NSCLC, CRC or GBM with expression of both PD-L1 and HLA-G positive, and are relapsed/refractory to at least two lines of standard-of-care therapy, or unwilling to undergo standard therapies. Relapse is defined as disease progression after last regimen; refractory is defined as intolerable or progressing disease (PD) to the last regimen.

For subject with non-squamous cell carcinoma using Immune checkpoint inhibitor, subjects should be with EGFR/ALK/ROS-1 wild type; for subject with squamous cell carcinoma using Immune checkpoint inhibitor, subjects should be with EGFR/ALK wild type.
CRC: Subject failed to chemotherapies (i.e. Folinicacid/ 5-fluorouracil/oxaliplatin (FOLFOX) and Folinicacid/ 5-fluorouracil/irinotecan (FOLFIRI)) and/or target therapies, including anti-EGFR (K-RAS and N-RAS wild type) (such as Cetuximab and Panitumumab) or anti-VEGF (such as Bevacizumab), Regorafenib and Lonsurf, according to the genetic testing results)
