Trial Outcomes & Findings for Preoperative Chemoradiotherapy and MK-3475 for Esophageal Squamous Cell Carcinoma (ACTS-29) (NCT NCT02844075)

NCT ID: NCT02844075

Last Updated: 2024-11-15

Results Overview

The primary endpoint of phase II study is to assess complete pathologic response rate. Definition of complete pathologic response is "no cancer cell, including lympho nodes" which corresponds with tumor regression score 0. Definition of pathologic response is as follows. Tumor regression score Grade 0 and 1 will be defined as "responder" and 2 and 3 will be considered as "non-responders"

Measure
Pembrolizumab
MK-3475(pembrolizumab): Neo-adjuvant chemoradiation period:The treatment consisted of taxol, carboplatin, pembrolizumab and radiation. The radiation treatment comprises 44.1Gy (2.1Gy/Fr, total 21Fr) and that will be about 5 weeks. Intensity modulated RT (IMRT) or 3D CRT (three-dimensional conformal radiotherapy) will be allowed. Surgery:Before surgery, abdomen/chest CT scan, endoscopic ultrasound (EUS), and gastroscopy with biopsy will be done. Surgery should be done within 12 weeks after last neo-adjuvant treatment. Adjuvant period:Adjuvant treatment with pembrolizumab 200mg every 2week (maximum 2 years) should be performed within 8 weeks after surgery (recommended period : 3-6 weeks after surgery). Gastroscopy and abdomen/chest CT scan will be performed at 6 month after surgery.

SECONDARY outcome

Timeframe: Up to 3 years

Population: Underwent surgery

Pathologic response rate is defined as tumor regression score. A score of '0' means 'No cancer cell, including lymph nodes'. A score of '1' means 'Single cells or small groups of cancer cells'. A score of '2' means 'Residual cancer cells outgrown by fibrosis'. A score of '3' means 'Minimum or no treatment effect'.
