PD-L1 Inhibitor Rechallenge After PD-1 Immunotherapy for Patients With Solid Tumor Beyond Lung Cancer

NCT05325684 | Unknown Phase 1

• 1 other identifier: PDL1-BEY-LUNG
• Study Type: interventional
• Target: 30
• Locations: 0 countries
• Sites: N/A

Brief 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.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• 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.

You may not qualify if:

• 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
