A single-arm exploratory clinical study to observe and evaluate the first-line treatment of elderly and treatment-intolerant patients with small cell lung cancer using benmelstobart in combination with anlotinib and etoposide.
Eligible patients are those with histologically or pathologically confirmed small cell lung cancer (SCLC) (AJCC 9th edition), who are treatment-naïve and considered elderly or intolerant to intensive therapy. Eligible subjects receive 4-6 cycles of benmelstobart injection combined with anlotinib hydrochloride and etoposide, followed by maintenance therapy with benmelstobart injection plus anlotinib hydrochloride, continued until disease progression or intolerable toxicity.
The study aims to evaluate the efficacy and safety of first-line treatment with benmelstobart injection in combination with anlotinib hydrochloride and etoposide in patients with advanced SCLC.
