Detailed Description
This study is a first-in-class open-label phase I human clinical study to evaluate the safety and tolerability of HLX26 with escalated doses in the treatment of patients with advanced/metastatic solid tumors or lymphomas. In this study, accelerated titration is combined with a 3 + 3 dose escalation method, and the patients will be given different doses(60mg, 150mg, 300mg, 500mg, 800mg Q3W) of HLX26 intravenously. Observation period of DLT lasts for 3 weeks after the first administration of HLX26.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: HLX26 Group The initial dose of HLX26 is 60 mg, and 5 dose levels are designed: 60 mg, 150 mg, 300 mg, 500 mg, and 800 mg (Q3W). Patients will receive the treatment until they have been in therapy for 2 years, develop progressive disease (PD) without any clinical benefit, death, intolerable toxicity, or withdraw the informed consent (whichever occurs first). |
