Spots Global Cancer Trial Database for Combination of Tislelizumab and Chemoradiotherapy in Esophageal Cancer (EC-CRT-002)

Study Description

Brief Summary: Definitive chemoradiotherapy (CRT) is the standard treatment option for unresectable locally advanced esophageal cancer (EC). However, as high as more than 40% of EC patients experienced locoregional recurrence after concurrent CRT. Immunotherapy targeting the PD-1/PD-L1 checkpoints has demonstrated promising activity in advanced EC. Recently, the combination of immunotherapy with CRT has emerged as a promising strategy to improve clinical outcomes in EC. The aim of this study was to evaluate whether the efficacy of tislelizumab (an anti-PD-1 antibody) plus induction chemotherapy followed by concurrent chemoradiotherapy would achieve a ≥71% 1-year progression-free survival rate, surpassing the historical 56% rate (NCT02403531) in patients with locally advanced esophageal squamous cell carcinoma (ESCC).

Detailed Description: A total of 114 patients with unresectable, locally advanced ESCC will be randomized to receive either tislelizumab plus induction chemotherapy followed by concurrent CRT and then 12 additional cycles of tislelizumab (Arm A) or tislelizumab plus the same induction and concurrent regimen without the maintenance of tislelizumab (Arm B). Patients will receive 2 cycles of 3-weekly schedule of induction chemotherapy, consisting of paclitaxel 135-175 mg/m2, cisplatin 75 mg/m2, and tislelizumab 200mg on day 1 prior to CRT. Then all patients will receive standard fractionation radiation therapy scheme: 50.4 Gy in 28 fractions, concurrently with paclitaxel 45mg/m2 and cisplatin 25 mg/m2 once weekly for 5 weeks and 2 cycles of tislelizumab. Patients in Arm A will receive 12 additional cycles of tislelizumab after the completion of CRT.
