A Phase II Single-arm Clinical Study in the Treatment of Locally Advanced Esophageal Cancer After Failed Neoadjuvant Chemoimmunotherapy

NCT07530549 | Not Yet Recruiting Phase 2 DMC

• 1 other identifier: NCC5675
• Study Type: interventional
• Target: 40
• Locations: 0 countries
• Sites: N/A

Brief Summary

The goal of this clinical trial is Iparomlimab and tuvonralimab (QL1706) combined with chemoradiotherapy in the treatment of locally advanced esophageal cancer after failed neoadjuvant chemoimmunotherapy. The main question it aims to answer is： Can it bring survival benefits and safet to patients？Subsequent evaluation will determine whether the patient undergoes surgical treatment. Follow-up will be conducted to assess the efficacy and safety of the treatment。

Study Arms (1)

Group1

EXPERIMENTAL

QL1706 and radical CCRT

Drug: QL1706

Interventions

QL1706 DRUG

QL1706(Iparomlimab and Tuvonralimab Injection): 5.0 mg/kg Q3W for 2 cycles; Radiotherapy Prescription Dose: 95% PGTV 40-50 Gy/20-25 fractions; Tegafur: 40-60 mg/m² twice daily (d1-14) every 3 weeks for 2 cycles; Evaluation for surgery: Patients will be divided into surgical and non-surgical groups. Participants who are not candidates for surgery may receive sequential boost radiotherapy to PGTV at a about dose of 60 Gy. Following radiotherapy, maintenance treatment with immunotherapy combined with chemotherapy will be administered for up to one year, until disease progression, death, or the occurrence of intolerable toxicity.

Also known as: radical CCRT

• Concurrent primary malignant tumors other than esophageal cancer (excluding cured basal cell carcinoma of the skin and carcinoma in situ of the cervix);
• Presence of brainstem, leptomeningeal metastasis, spinal cord metastasis, or compression;
• Complicated with severe cardiovascular diseases, such as uncontrolled heart failure, coronary heart disease, cardiomyopathy, uncontrolled arrhythmia, uncontrolled hypertension, or history of myocardial infarction within the past 5 years; and complicated with other uncontrolled acute or chronic diseases;
