A Study of Adebrelimab Combined With Famitinib and Chemotherapy in the Treatment of ES-SCLC.

This study plans to recruit 40 patients with extensive-stage small cell lung disease who have not received treatment, observe and evaluate the effectiveness and safety of adebrelimab combined with famitinib and chemotherapy.

• adebrelimab (Drug), also known as SHR-1316: adebrelimab IV
• famitinib (Drug), also known as SHR1020: famitinib PO
• chemotherapy (Drug), also known as cisplatin/carboplatin and etoposide: chemotherapy IV

Primary outcomes

• 6-month progression-free survival [up to 6 months]: Proportion of disease progression or death from randomization to 6 months of treatment.

Secondary outcomes

• 12-month progression-free survival [up to 12 months]: Proportion of disease progression or death from randomization to 12 months of treatment.
• Objective Response Rate [up to 24 months]: Determined using RECIST v1.1 criteria, defined as best overall response (CR or PR) across all assessment time points during the period from enrolment to termination of trial treatment.
• Disease control rate [up to 24 months]: Disease Control Rate, determined using RECIST v1.1 criteria.
• Overall Survival [up to 24 months]: Defined as the time from randomization to death from any cause.
• AEs [up to 24 months]: Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0.
• QoL [up to 24 months]: Defined as time from randomization to deterioration on each of the EORTC QLQ-C30 symptom subscales
• Progression-Free-Survival [up to 24 months]: Defined as the time from randomization to the first occurrence of disease progression with use of RECIST v1.1 or death from any cause, whichever occurs first.
