 This is a first-in-human, open-label, sequential dose escalation study to evaluate AB0024 in patients with advanced solid tumors. The study will consist of two parts: Part A will be a dose escalation, and Part B will be a dose expansion.The primary objective of this study is to characterize the safety, tolerability, and PK of AB0024 after multiple IV administrations in patients with advanced solid tumors. The secondary objectives are to measure the tumor response by modified RECIST and to evaluate the formation of anti-AB0024 antibodies.
