Summary

This is a phase II study evaluating a new combination therapy for untreated extensive-stage small cell lung cancer. The treatment involves an initial phase with the drug Bemotuzumab plus standard chemotherapy and anlotinib, followed by a phase combining Bemotuzumab, anlotinib, and chest radiation. The primary objectives are to assess the efficacy of this approach in delaying cancer growth (progression-free survival) and to evaluate its safety in approximately 25 patients.

Detailed description

This is an exploratory Phase II clinical trial for previously untreated extensive-stage small cell lung cancer (ES-SCLC). The study evaluates a novel three-phase sequential treatment strategy: patients first receive induction therapy with Bemotuzumab combined with standard chemotherapy and Anlotinib; those achieving disease control then proceed to consolidation therapy with Bemotuzumab, Anlotinib, and concurrent thoracic radiotherapy; followed by a maintenance phase with Bemotuzumab plus Anlotinib. The primary objectives are to assess the regimen's efficacy in prolonging progression-free survival (PFS) and to observe its safety profile. The study plans to enroll approximately 25 patients.

Conditions

• Small Cell Lung Cancer (SCLC)
• SCLC, Extensive Stage

Interventions

Type	Name	Description
COMBINATION_PRODUCT	Bemotuzumab + Anlotinib + Chemotherapy + Radiotherapy	This is a multi-phase combined modality regimen. Induction Phase (4 cycles): Bemotuzumab (1200mg IV, Day1 q3w) + Platinum/Etoposide chemotherapy (Carboplatin \[AUC5\] or Cisplatin \[75-80 mg/m²\] on Day1, plus Etoposide \[100 mg/m² IV, Days1-3\]) + oral Anlotinib (12mg, Days1-14, then 7 days off). Consolidation Phase (2 cycles): Bemotuzumab (same dose) + Anlotinib (same schedule) + concurrent Thoracic Radiotherapy (5 Gy per fraction for 5 fractions). Maintenance Phase: Bemotuzumab (q3w) + Anlotinib until disease progression or unacceptable toxicity. Anlotinib Dose Modification: The dose may be increased to 12mg if well tolerated. For toxicity, it can be reduced sequentially (12mg→10mg→8mg). Treatment is discontinued if 8mg is not tolerated. For subjects at 8mg, one dose re-escalation is permitted if, in the investigator's judgement, clinical benefit is possible and safety is stable.
