QL1706: Dose: 5 mg/kg ; intravenous infusion (ivgtt), administered on Day 1 of each cycle and every 3 weeks (21 days).

Treatment will continue until loss of clinical benefit, occurrence of intolerable toxicity, patient or physician decision to discontinue treatment, death of the patient receiving the experimental treatment, or completion of 2 years of dosing (35 dosing cycles), withdrawal of informed consent by the subject, pregnancy of the subject, noncompliance with protocol or procedural requirements, or for administrative reasons.

3. have at least one measurable lesion as assessed by the investigator according to RECIST 1.1.

   Note: Measurable target lesions cannot be selected from previous radiotherapy sites. If the target lesion at the site of prior radiotherapy is the only optional target lesion, the investigator is required to provide anterior and posterior imaging data showing significant progression of this lesion.
