Neoadjuvant QL1706 Therapy for ESCC

A Single-Arm Study of Iparomlimab and Tuvonralimab (QL1706) in Combination With Chemotherapy as Neoadjuvant Therapy for Locally Advanced Resectable Esophageal Squamous Cell Carcinoma

This study plans to enroll 32 patients with resectable esophageal squamous cell carcinoma. The treatment regimen consists of Iparomlimab and Tuvonralimab(QL1706) combined with chemotherapy: intravenous infusion of QL1706 (5 mg/kg, q3w) in combination with albumin-bound paclitaxel (260 mg/m² on day 1, q3w) plus cisplatin (75 mg/m² on day 1, q3w) or carboplatin (AUC 5 on day 1, q3w) for 3 cycles. Surgical resection will be performed 3-6 weeks after treatment completion. Pre-treatment and surgical tissue specimens will be collected for analysis of tumor immune microenvironment changes using digital gene quantification technology. Peripheral blood samples will be obtained for dynamic ctDNA monitoring at four time points: within 7 days pre-treatment, 7 days pre-surgery, 7-30 days post-surgery, and 6 months post-surgery. The primary endpoint is the pathological complete response (pCR) rate, and secondary endpoints include major pathological response (MPR) and adverse reactions.

2. The subjects are using immunosuppressive agents or systemic or absorbable local hormones to achieve the purpose of immunosuppression (dose>10mg/day prednisone or other effective hormones), and continue to use them within 2 weeks before enrollment;
3. Severe allergic reaction to other monoclonal antibodies;
4. There are cardiac clinical symptoms or diseases that are not well controlled, such as: (1) heart failure above NYHA grade 2 (2) unstable angina pectoris (3) myocardial infarction within one year (4) clinically significant supraventricular or ventricular arrhythmias requiring treatment or intervention (5) qtc>450ms (male); Qtc>470ms (female);

7. Genetic or known to exist Acquired hemorrhage and thrombotic tendency (such as hemophilia, coagulation dysfunction, thrombocytopenia, hypersplenism, etc.) or arteriovenous thrombosis events in recent 6 months (until the first use of shr-1210);
8. Subjects with active infection or fever of unknown origin>38.5 degrees during screening and before the first administration;
9. Patients with previous and current objective evidence of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-related pneumonia, and severe impairment of lung function;
10. Subjects with congenital or acquired immune deficiency (such as HIV infected), or active hepatitis (hepatitis B reference: HBV DNA detection value exceeds the upper limit of normal value; Hepatitis C reference: HCV virus titer or RNA detection value exceeds the upper limit of normal value);

15. Live vaccines were administered less than 4 weeks before the study or during the study period;
16. According to the judgment of the investigator, the subject has other factors that may lead to the forced termination of this study, such as other serious diseases (including mental diseases) requiring combined treatment, serious laboratory abnormalities, accompanied by family or social factors, which will affect the safety of the subject, or the collection of data and samples.
