简要总结
This phase I trial studies how well atezolizumab before and/or with standard of care chemoradiotherapy works in immune system activation in patients with stage IB2, II, IIIB, or IVA cervical cancer that has spread to the lymph nodes. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving atezolizumab before and/or with chemoradiotherapy may lower the chance of tumors growing or spreading.
详细描述
PRIMARY OBJECTIVES:
I. To determine whether differences in sequencing of atezolizumab and chemoradiation result in differential immune activation, as determined by clonal expansion of T cell receptor beta (TCRB) repertoires in peripheral blood on day 21.
SECONDARY OBJECTIVES:
I. To investigate the feasibility of administration of the anti PD-L1 antibody (atezolizumab) as an immune primer and concurrent with chemoradiation (CRT) therapy in patients with locally advanced cervical cancer.
II. To determine the nature and degree of toxicity of the anti PD-L1 antibody (atezolizumab) administered as an immune primer and concurrent with chemoradiation (CRT) therapy in patients with locally advanced cervical cancer.

结局指标
主要结局
Immune Response
时间窗: Arm A: 42 days from the first dose of Atezolizumab Arm B: 21 days from the first dose of Atezolizumab
The immune response is measured by total T cell receptor beta (TCRB) clonal expansion in peripheral blood at day 21 from baseline using Adaptive Biotechnologies' immunoSEQ platform from Day -21 to Day 21 for group 1 (i.e., Arm A), and from Day 0 to Day 21 for group 2 (i.e., Arm B). The higher number of total TCR clonal expansion indicates better immune response.
