Brief Summary:
This dose escalation and dose expansion study is to evaluate and characterize the tolerability and safety profile of single agent KN035 in Chinese adult subjects with unresectable advanced carcinoma.

Condition or disease Intervention/treatment Phase
Solid Tumors Hepatocellular Carcinoma Drug: KN035 Phase 1

Detailed Description:

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.
