Dose escalation study is to evaluate the safety and tolerability of KN035 in advanced and metastatic solid tumor. Six dose levels are planned and include: 0.1, 0.3, 1.0, 2.5, 5, 10 mg/kg/dose. Subjects will be assigned to a dose level in the order of study entry. The first cohort of 1 subject will receive KN035 at 0.1 mg/kg/dose as a subcutaneous (sc) injection every week for a total of 4 injections (Days 1, 8, 15 and 22) in the first 28-day cycle. For the first 2 cohorts (0.1 and 0.3 mg/kg/dose), only one subject will be enrolled in each cohort until 1 subject experiences a ? Grade 2 drug-related adverse event in the first cycle, then 2 additional subjects will be enrolled at this cohort. Thereafter, the study will become the traditional 3+3 design with 3 or 6 subjects treated at this dose level and all subsequent dose levels depending upon the incidence of DLTs. However, if no ? Grade 2 drug-related adverse event occurs in the first 2 cohorts, starting with cohort 3, the study will become the traditional 3+3 design with 3 or 6 subjects enrolled. Dose expansion study is planned to conduct in advanced hepatocellular cancer patients at 2.5 mg/kg and 5 mg/kg dose level, respectively.
