Extensive-Stage Small Cell Lung Cancer
Conditions
Brief summary
This is an open-label, multi-center Phase II study designed to evaluate the efficacy and safety of Surufatinib plus anti-PD-1/L1 as maintenance therapy after first-line standard of care in patients with ES-SCLC.
Detailed description
This study consists of two parts, i.e., a single-arm Phase IIa study and a randomized, controlled Phase IIb study. All the enrolled patients will be patients with ES-SCLC who did not have PD (determined as per the RECIST v1.1) after prior platinum-based chemotherapy in combination with an anti-PD-1/L1. Approximately 20 patients are planned to be enrolled in the single-arm Phase IIa study to preliminarily observe the efficacy and safety. Approximately 40 patients are planned to be enrolled in the randomized and controlled Phase IIb study with 20 patients per group.
Interventions
DRUGSurufatinib
The recommended dosage is 250 mg orally once daily (QD) within 1 hour after breakfast for continuous administration.
DRUGAnti-PD-1/L1
Anti-PD-1/L1 therapy, Q3W or Q4W, the same immune checkpoint inhibitor from patients' first-line therapy.

Intervention model description
The study consists of two parts, i.e., a single-arm Phase IIa study and a randomized (1:1), controlled Phase IIb study. Phase IIa: It is planned that 20 patients will be enrolled to receive treatment with Surufatinib plus anti-PD-1/L1, the same immune checkpoint inhibitor from patients' first-line therapy . Phase IIb: It is planned that 40 patients will be enrolled to receive the following treatments: Group A: Patients will receive treatment with Surufatinib plus anti-PD-1/L1, the same immune checkpoint inhibitor from patients' first-line therapy. Group B: Patients will receive treatment with anti-PD-1/L1, the same immune checkpoint inhibitor from patients' first-line therapy.
