简要总结
This phase III trial compares the addition of induction chemotherapy, with carboplatin, paclitaxel and pembrolizumab, to chemotherapy and radiation, with cisplatin and pembrolizumab followed by pembrolizumab maintenance for the treatment of patients with cervical cancer that has spread to nearby tissue or lymph nodes (locally advanced). Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Adding induction chemotherapy to the usual treatment of chemotherapy and radiation followed by maintenance may be more effective in treating patients with high risk, locally advanced cervical cancer.
详细描述
PRIMARY OBJECTIVE:
I. To determine whether induction immunotherapy (IO) and chemotherapy prior to concurrent chemoradiation therapy (CCRT) + IO improves progression-free survival (PFS) compared to CCRT+IO alone.
SECONDARY OBJECTIVES:
I. To assess whether induction IO and chemotherapy prior to CCRT+IO improves the overall survival (OS) compared to CCRT+IO alone.
II. To determine the nature and degree of toxicity of induction IO and chemotherapy prior to CCRT + IO as compared to concurrent CCRT+IO as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0.

结局指标
主要结局
Progression free survival (PFS)
时间窗: From randomization to time of progression or death from any cause, whichever occurs first, or date of last contact if neither progression nor death has occurred, up to 7 years
Analysis will be performed using a one-sided log-rank test stratified by factors declared at randomization when (at least) 190 PFS events are observed in both arms. Patients will be grouped by their randomized treatment for intention-to-treat (ITT) analyses, supported by patients in ITT population. Treatment hazard ratio and confidence will be estimated using Cox proportional hazard models specified with a main effect for the randomized treatment assignment and stratified by factors declared at randomization. PFS at 2 years will be estimated using Kaplan-Meier method for each arm.
