About

This study is an open-label first-in-human phase I clinical study to evaluate the safety and tolerability of HLX42.

Full description

This study is an open-label first-in-human phase I clinical study to evaluate the safety and tolerability of HLX42 with escalated doses in the treatment of patients with advanced/metastatic solid tumors. In this study, a 3 + 3 dose escalation method will be adopted, and the patients will be administered with HLX42 at different doses via intravenous infusion. The DLT observation period lasts for 3 weeks after the first administration of HLX42.

  6. Any poorly-controlled cardiovascular and cerebrovascular clinical symptoms or diseases;
  7. Patients who have been assessed as unsuitable for inclusion by the investigator, due to brain metastases, spinal cord compression, or cancerous meningitis with clinical symptoms, or uncontrolled brain or spinal cord metastases that have been evidenced;
  8. Patients who have received long-term systemic steroids treatment (equivalent to prednisone > 10 mg/day) or immunosuppressive agents of any other forms, which should be discontinued at least 2 weeks prior to the first infusion of the investigational product;
