Pembrolizumab Plus Neoadjuvant Chemotherapy vs. Neoadjuvant Chemoradiotherapy for Locally Advanced ESCC (KEYSTONE-002)

Phase 3
Recruiting
Conditions
Esophageal Squamous Cell Carcinoma
Interventions
Biological: Pembrolizumab
Radiation: neoadjuvant chemoradiotherapy
Registration Number
NCT04807673
Lead Sponsor
Tianjin Medical University Cancer Institute and Hospital
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.

Inclusion Criteria

  7. Demonstrate adequate organ function ;
  8. Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours before receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required;
  9. Be willing to provide tissue, blood, and urine samples. Tissue should be from a newly obtained core or excisional biopsy of a tumor lesion through repeated biopsies. Newly-obtained is defined as a specimen obtained up to 4 weeks (28 days) before initiation of treatment on Day 1.
  10. Have not received systemic or local treatment for esophageal cancer in the past.
Exclusion Criteria
  1. Ineligibility or contraindication for esophagectomy;
  2. Prior therapy (operation, radiotherapy, immunotherapy, or chemotherapy) for esophageal cancer
  3. Active autoimmune disease or history of autoimmune disease;
  4. Requiring systemic treatment with either corticosteroids or other immunosuppressive medications;
  5. Subjects with a history of symptomatic interstitial lung disease;
  6. History of allergy to study drug components;
  7. Women must not be pregnant or breast-feeding;
  8. Patient has received prior chemotherapy, radiotherapy, target therapy ,and immune therapy for this malignancy or any other past malignancy;
  9. 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.

Primary Outcome Measures
NameTimeMethod
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
NameTimeMethod
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

The quality of life will be assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer patients (EORTC QLQ-C30) questionnaire. Patients will be invited to finish the questionnaire at the first day of randomization, before surgery and after surgery (3m, 6m, 12m and 24 months).

Quality of life differences (EORTC QLQ-OES18)2.5 years
