Chemoradiation and Pembrolizumab Followed by Pembrolizumab and Lenvatinib Before Surgery for the Treatment of Non-metastatic Esophageal or Esophageal/Gastroesophageal Junction Cancer

• Status: Recruiting
• Trial end date: 2023-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies the effect of chemoradiation and pembrolizumab followed by pembrolizumab and lenvatinib before surgery in treating patients with esophageal or esophageal/gastroesophageal junction cancer that has not spread to other places in the body (non-metastatic). Pembrolizumab is an immunotherapy drug that works by harnessing the immune system to attack cancer. Lenvatinib is an anti-cancer drug that works by stopping or slowing down the growth of cancer cells. Chemotherapy drugs, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving chemoradiation and pembrolizumab followed by pembrolizumab and lenvatinib before surgery may kill more tumor cells.
