NCT06143748 | RECRUITING | Esophagus Cancer

Combination of Cadonilimab and Chemoradiotherapy in Esophageal Cancer (EC-CRT-006)
Sponsor:

Sun Yat-sen University

Information provided by (Responsible Party):

Brief Summary:

Definitive chemoradiotherapy (CRT) is the standard treatment option for unresectable locally advanced esophageal cancer. However, as high as more than 40% of patients with esophageal cancer experienced locoregional recurrence after definitive CRT. Immune checkpoint inhibitors targeting PD-1/PD-L1 and/or CTLA-4 have shown substantial clinical benefits in advanced esophageal cancer. Recently, the combination of immunotherapy with CRT has emerged as a promising strategy to improve clinical outcomes in esophageal cancer. The aim of this study was to evaluate the efficacy and safety of cadonilimab (a bispecific PD-1/CTLA-4 antibody) combined with induction chemotherapy followed by definitive radiotherapy in patients with locally advanced esophageal squamous cell carcinoma.

Condition or disease

Esophagus Cancer

Intervention/treatment

Cadonilimab

Paclitaxel and cisplatin

intensity-modulated radiotherapy

Phase

PHASE2

Detailed Description:

A total of 46 patients with unresectable, locally advanced ESCC will be enrolled to receive cadonilimab plus induction chemotherapy followed by definitive radiotherapy and then 12 additional cycles of maintenance therapy with cadonilimab. Patients will receive 2 cycles of 3-weekly schedule of induction chemotherapy, consisting of paclitaxel 135 mg/m2, cisplatin 75 mg/m2, and cadonilimab 10 mg/kg on day 1 prior to CRT. Then all patients will receive standard fractionation radiation therapy scheme: 50.4 Gy in 28 fractions, concurrently with 2 cycles of cadonilimab. After the completion of radiotherapy, patients will then receive 12 additional cycles of cadonilimab.
