Brief Summary

Based on the preclinical rationale for combining surufatinib with immunotherapy, and the clinical efficacy observed with surufatinib in extensive-stage small cell lung cancer (ES-SCLC), the investigators hypothesize that incorporating surufatinib into the ADRIATIC regimen could further enhance survival in LS-SCLC. To evaluate this approach, the investigators plan to conduct a single-arm Phase II study to explore the safety and efficacy of concurrent chemoradiotherapy combined with toripalimab and surufatinib in treating LS-SCLC.

Study Arms (1)

The study group

EXPERIMENTAL

In this single-arm, patients are planned to receive four cycles of etoposide combined with either cisplatin or carboplatin, along with toripalimab and surufatinib. During chemotherapy, patients will undergo concurrent radiotherapy. Following chemoradiotherapy, consolidation treatment with toripalimab and surufatinib will be administered. Prophylactic cranial irradiation (PCI) is recommended prior to the initiation of immunotherapy consolidation.

Interventions

Chemotherapy DRUG

Etoposide combined with cisplatin or carboplatin, administered every three weeks for a total of four cycles.

Immunotherapy DRUG

Toripalimab was administered concurrently with chemotherapy, every three weeks for four cycles.

The study group

Angio-immuno kinase inhibitor DRUG

The study group

Prophylactic Cranial Irradiation RADIATION

PCI is recommended after the completion of chemoradiotherapy.

The study group

Consolidation Therapy with Toripalimab and Surufatinib DRUG

Patients achieving complete response (CR), partial response (PR), or stable disease (SD) following chemoradiotherapy will receive consolidation therapy. Toripalimab: 240 mg intravenously on day 1, every three weeks. Surufatinib: 200 mg orally on days 1-14, every three weeks.

• Males with azoospermia do not need to follow contraception requirements.
• WOCBP who are not sexually active do not need to follow contraception requirements but must still undergo pregnancy testing as outlined.

• Serum bilirubin ≤1.5 × upper limit of normal (ULN). AST and ALT ≤2.5 × ULN.

You may not qualify if:

• Participation in Another Clinical Trial: Simultaneous participation in another clinical trial, unless it is an observational (non-interventional) study.
