Study of Sintlimab Maintenance Therapy in Patients With Extensive Small Cell Lung Cancer

Overview

Small cell lung cancer is a highly aggressive malignancy. Currently, there is no effective regimen for patients after the progression offirst-line chemotherapy. The prognosis of patients with extensive disease is very poor, and the improved therapeutic efficacy is urgently needed. Most patients with small cell lung cancer have a long history of smoking, and the tumor mutation burden is relatively high, which provides potential for immunological checkpoint inhibitors represented by PD-1 antibodies. A number of studies have shown that chemotherapy combined with adoptive cellular immunotherapy could prolong the survival of patients. This study is a clinical study to explore the efficacy and safety of maintenance therapy with sintilimab after 4-6 cycles of first-line chemotherapy combined with adoptive cellular immunotherapy in patients with advanced small cell lung cancer.

Full Title of Study: “Clinical Study of Sequential Sequential Sintilimab Maintenance Therapy in Patients With Extensive Small Cell Lung Cancer After Chemotherapy Combined With Adoptive Cellular Immunotherapy”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: N/A
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: May 31, 2021

Interventions

  • Drug: sintilimab maintenance
    • the patients with CR, PR or SD after the chemotherapy plus R-CIK will receive sintilimab maintenance therapy. The dose of sintilimab is fixed at 200mg every three weeks.

Arms, Groups and Cohorts

  • Experimental: treatment group
    • phlebotomation 50ml 1-7 days before chemotherapy for culture of R-CIK cells chemotherapeutic regimen EP or EC as follows: VP-16 100mg/m2 D1-3 plus cisplatin 75mg/m2 D1 or VP-16 100mg/m2 D1-3 plus carboplatin AUC=5 D1 R-CIK cells were transfused back to the patients 2-7 days after the end of chemotherapy, and the amount of R-CIK cells returned each time was about 5×109 three weeks each cycle efficacy evaluated every two cycles patients with the efficay is CR, PR or SD after 4-6 cycles enter the sintilimab maintenance therapy for one year or until the progression of disease, or occurrence of intolerable adverse events. the dose of sintilimab is fixed dose of 200mg every three weeks

Clinical Trial Outcome Measures

Primary Measures

  • median survival time
    • Time Frame: two years.
    • the period from the day of enrollment to the date of death

Secondary Measures

  • progression-free survival
    • Time Frame: six months
    • the period from the day of enrollment to the date of confirmed progression or death depending on which one occurs first.
  • objective response rate of sintilimab
    • Time Frame: six month
    • from the date of first dose of sintilimab to the date of confirmed progression following
  • adverse events rate of sintilimab
    • Time Frame: one year
    • the rate of adverse events during the maintenance therapy of sintilimab
