简要总结
This study to evaluate the preliminary efficacy, safety and pharmacokinetics of PM8002 combined with PM1009 in Patients with first-line Hepatocellular Carcinoma.
详细描述
The study is divided into two parts. The first part is a phase Ib, single-arm study, which is planned to enroll 3-28 subjects.
The second part is a phase II randomized, parallel-controlled, four-arm, open-label study, which is planned to enroll approximately 120 subjects.
