Pembrolizumab Plus Neoadjuvant Chemotherapy vs. Neoadjuvant Chemoradiotherapy for Locally Advanced ESCC (KEYSTONE-002)
- Conditions
- Esophageal Squamous Cell Carcinoma
- Interventions
- Registration Number
- NCT04807673
- Brief Summary
The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus paclitaxel, cisplatin as neoadjuvant therapy followed by surgery, and pembrolizumab as adjuvant therapy, compared with neoadjuvant chemoradiotherapy and surgery for locally advanced ESCC in multicenter.
- Detailed Description
Preoperative chemoradiotherapy with radical surgery is the recommended treatment for locally advanced esophageal squamous cell carcinoma (ESCC) in the NCCN guidelines. But many patients refused or abandon radiotherapy because of the intolerable adverse effects. The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus paclitaxel, cisplatin as neoadjuvant therapy followed by surgery, and pembrolizumab as adjuvant therapy, compared with neoadjuvant chemoradiotherapy and surgery for locally advanced ESCC in multicenter. The primary study hypothesis is that Event Free Survival (EFS) is superior with pembrolizumab plus neoadjuvant chemotherapy compared with neoadjuvant chemoradiotherapy in participants with ESCC.

- Have not received systemic or local treatment for esophageal cancer in the past.
- Ineligibility or contraindication for esophagectomy;
- Prior therapy (operation, radiotherapy, immunotherapy, or chemotherapy) for esophageal cancer
- Active autoimmune disease or history of autoimmune disease;
- Requiring systemic treatment with either corticosteroids or other immunosuppressive medications;
- Subjects with a history of symptomatic interstitial lung disease;
- History of allergy to study drug components;
- Women must not be pregnant or breast-feeding;
- Patient has received prior chemotherapy, radiotherapy, target therapy ，and immune therapy for this malignancy or any other past malignancy;
- Underlying medical conditions that, in the Investigator's opinion, will make the administration of study drug hazardous or obscure the interpretation of toxicity or adverse events.

Group Intervention Description Pembrolizumab+ Paclitaxel+Cisplatin+ Surgery+Pembrolizumab (228) Pembrolizumab Participants receive pembrolizumab 200 mg intravenously (IV) on Day 1 every 3 weeks (Q3W), paclitaxel 135mg/m\^2 IV on Day 2 Q3W, and cisplatin 80 mg/m\^2 IV on Day 2 Q3W, a total of three cycles. All treatments will be beginning on Day 1 of each 3-week dosing cycle. Surgery should be done within 4-6 weeks after the last neoadjuvant treatment. After surgery, pembrolizumab 200 mg IV on Day 1 Q3W lasting one year.

- Primary Outcome Measures
Name Time Method Event Free Survival (EFS) Up to approximately 2.5 years EFS is defined as the time from randomization to the first documented disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by investigator, or recurrence, or metastasis, or death due to any cause, whichever occurs first. For this analysis, EFS will be assessed in participants with ESCC.
- Secondary Outcome Measures
Name Time Method Overall Survival (OS) 3 and 5 years OS is defined as the time from randomization to death due to any cause.
Disease Free Survival (DFS) 3 and 5 years Percentage of Participants With DFS, as Assessed by RECIST 1.1. DFS is defined as the time from randomization to the first documented disease progression of local recurrence or distant metastasis or death due to any cause.
Major pathologic response (MPR) 1 month after resection MPR is defined as viable tumor comprised ≤ 10% of resected tumor specimens.
Objective response rate (ORR) 1 month after resection ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by investigator. For this analysis, ORR will be assessed in all participants.
Pathologic Complete Response (PCR) 1 month after resection PCR is defined as pT0N0M0
assessment in perioperation perioperative period R0 resection rate， Time of operation， Quantity of bleeding， Thoracic Drainage， Days of Hospitalization， Rate of Operative Complication， Mortality of perioperation
