简要总结
This is a pilot study of patients who previously received platinum chemotherapy with recurrent SCLC to evaluate the change in the ratio of intratumoral Teff/Treg cells and clinical benefit of treatment with nivolumab and ipilimumab.
详细描述
The primary objective of this study is t assess whether the change in the ratio of effector T cells (Teff) to regulatory T cells (Treg), i.e. CD8 positive/FoxP3 expressing CD4 T cells, between pre- and on- treatment biopsies, will predict clinical response in patients with recurrent SCLC treated with combination therapy with nivolumab and ipilimumab.
Secondary objectives of the study include: to determine the objective response rate per RECIST 1.1 and immune-related response criteria, duration of response, progression free survival, and overall survival with nivolumab and ipilimumab in patients with recurrent SCLC; to evaluate changes in the tumor immune microenvironment and blood after treatment with ipilimumab and nivolumab; and to evaluate circulating tumor DNA (ctDNA) as a marker for response to therapy.

研究组 & 干预措施
Nivolumab and Ipilimumab
Patients will be treated with nivolumab 1 mg/kg and ipilimumab 3 mg/kg, starting on Day 1. Patients will receive 4 doses of each nivolumab and ipilimumab and then will receive nivolumab 240 mg starting week 13 (day 85) every 2 weeks until progression, unacceptable toxicity, withdrawal of consent, or the study ends, whichever occurs first.
干预措施: Combination immunotherapy with Ipilimumab and Nivolumab (Drug)
结局指标
主要结局
Change in the ratio of Teff/Treg cells
时间窗: Up to 24 months
The primary analysis will use the nonparametric Mann-Whitney sign test to compare the change in the ratio of Teff/Treg cells in those patients who respond or not to treatment. This test compares the rate of response in those with above and below Teff/Treg ratio.
次要结局
- Response rate(Up to 24 months)
- Duration of response(Up to 24 months)
- Progression-free survival(Up to 24 months)
