Clinical Trial Summary

Anti-PD-L1 immune checkpoint inhibitor, is approved for the treatment of patients with unresectable, Stage III NSCLC whose disease has not progressed following concurrent platinum-based chemotherapy and radiation therapy, or as first-line treatment of patients with ES-SCLC in combination with etoposide and either carboplatin or cisplatin in China. The clinical data regarding the PD-L1 inhibitor in other solid tumors are limited.Investigators would observe and analyze the effectiveness and safety of PD-L1 inhibitor for patients with advanced - solid tumors beyond lung cancer after muti-line therapy to explore the synergistic effect of PD-L1 inhibitor rechallenge after PD-1immunotherapy.

Recruitment information / eligibility

• Status: Not yet recruiting
• Enrollment: 30
• Est. completion date: December 2023
• Est. primary completion date: December 2023
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Signed Informed Consent Form

• Ability to comply with protocol

• Aged = 18 years

• Histologically documented advanced solid tumor beyond lung cancer

• Disease progression during or following at least one line treatment containing PD-1 immunotherapy.

• Measurable disease, as defined by RECIST v1.1

• ECOG performance status of 0 or 1

• Life expectancy = 12 weeks

• Adequate hematologic and end organ function, defined by the following laboratory results obtained within 14 days prior to the first study treatment:

ANC = 1.5 × 109/L (without granulocyte colony-stimulating factor support within 2 weeks of laboratory test used to determine eligibility) WBC counts > 2.5 × 109/L and < 15 × 109/L Lymphocyte count = 0.5 × 109/L Serum albumin = 2.5 g/dL Platelet count = 100 × 109/L (without transfusion within 2 weeks of laboratory test used to determine eligibility) Hemoglobin = 9.0 g/dL Patients may be transfused or receive erythropoietic treatment to meet this criterion.

Liver function tests meeting one of the following criteria:

AST or ALT = 2.5 × upper limit of normal (ULN), with alkaline phosphatase

= 2.5 × ULN or AST and ALT = 1.5 × ULN in conjunction with alkaline phosphatase > 2.5 × ULN Serum bilirubin = 1.5 × ULN Patients with known Gilbert's disease who have serum bilirubin level = 3 × ULN may be enrolled. INR and aPTT = 1.5 × ULN This applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose for at least 1 week prior to randomization. Creatinine clearance = 30 mL/min Cockcroft-Gault, Chronic Kidney Disease Epidemiology Collaboration, or Modification of Diet in Renal Disease formulas may be used for creatinine clearance calculation. Note that 24-hour urine collection is not required but is allowed.

Exclusion Criteria:

• Active or untreated CNS metastases as determined by computed tomography (CT) or magnetic resonance imaging (MRI) evaluation during screening and prior radiographic assessments

• Leptomeningeal disease

• Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures

• Uncontrolled hypertension

• Autoimmune disease

• Had undergone a serious anaphylactic reaction in previous immunotherapy
