Brief Summary:
This is a single arm, multi-center clinical trial. The goal of this clinical trial is to evaluate the efficacy, safety and biomarkers of Tafolecimab combined with Sintilimab and Chemotherapy as first-line treatment for patients with extensive-stage small cell lung cancer (ES-SCLC). Tafolecimab is a recombinant fully humanized monoclonal antibody against proprotein convertase subtilisin/kexin type 9 (PCSK-9), which can reduce low-density lipoprotein-C levels and increase the expression level of major histocompatibility complex class I (MHC-I) on tumor cells. Sintilimab is a fully humanized IgG4 monoclonal antibody targeting programmed cell death protein 1 (PD-1).
Detailed Description:
Eligible patients will receive 4 cycles of Tafolecimab (300mg, sc, d1, Q3W) in combination with Sintilimab (200mg, iv, d1, Q3W), along with etoposide and either carboplatin (AUC 5 mg/mL/min) or cisplatin (75 mg/m2) administered intravenously on days 1, 2, and 3 of each 3-week cycle for up to 4 to 6 cycles. Subsequently, patients will receive maintenance therapy with Sintilimab and Tafolecimab until disease progression, the occurrence of intolerable toxicities, or the treatment duration reaches 2 years. If the investigator assesses potential evidence of clinical benefit, continuing treatment after disease progression is permitted.
PRIMARY OBJECTIVES:
I. To evaluate the progression-free survival (PFS) of Tafolecimab combined with Sintilimab and chemotherapy as first-line treatment regimens for patients with extensive-stage small cell lung cancer (ES-SCLC).
SECONDARY OBJECTIVES:
I. To evaluate the safety of of Tafolecimab combined with Sintilimab and chemotherapy as first-line treatment regimens for patients with ES-SCLC.
II. To evaluate the PFS rate, objective response rate (ORR), disease control rate (DCR), duration of response (DOR), overall survival (OS) rate and OS of Tafolecimab combined with Sintilimab and chemotherapy as first-line treatment regimens for patients with ES-SCLC.
TERTIARY OBJECTIVES:
I. To evaluate whether Tafolecimab combined with Sintilimab and chemotherapy as first-line treatment for patients with ES-SCLC could upregulate the expression of MHC-I on SCLC tumor cells.
II. To explore tissue and liquid biopsy biomarkers that may be predictive of response or primary resistance to Tafolecimab combined with Sintilimab and chemotherapy.
