On-target PD effects were consistent with PD-L1 inhibition and data reported by anti-PD-(L)1 mAbs. Preliminary anti-tumor activity was observed, and further studies are warranted to explore the efficacy in a larger number of patients.
Results ABSK043 demonstrated strong in vivo synergy with several therapeutic agents such as carboplatin, a key component of the widely used CRC standard-of care chemotherapy treatment regimen, as well as other target therapy or immune-oncology agents. Conclusions Taken together, these data for the first time demonstrated broad combination synergy of a small molecule PD-L1 antagonist with other agents and provided basis for potential clinical evaluation of these combination treatment for cancer patients.
