Neoadjuvant Ivonescimab（AK112） Combined With Chemotherapy in Patients With Resectable Esophageal Squamous Cell Carcinoma
Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University
Summary
In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma patients was not significantly decreased. It is recommended that a treatment strategy be employed that integrates surgery with radiotherapy, chemotherapy, or immunotherapy, in order to enhance overall survival by improving local-regional tumor control and addressing microscopic metastases. Clinical research indicates that combining anti-PD-1/L1 and anti-VEGF antibodies enhances anti-tumor effects in esophageal squamous cell carcinoma. Ivonescimab, a humanized bispecific monoclonal antibody targeting PD-1/VEGF. This single-arm, prospective, exploratory study is planned to evaluate the combination of ivonescimab and chemotherapy in neoadjuvant therapy for resectable esophageal squamous cell carcinoma, with the aim of providing new therapeutic options for this condition.

Interventions
Ivonescimab（AK112), Albumin paclitaxel, carboplatin AUC=5, neoadjuvant therapy
Ivonescimab（AK112) 20mg/kg, IV, Day 1; Albumin paclitaxel 260mg/m2, Day 1; carboplatin AUC=5, Day 1; Preoperative neoadjuvant therapy for 3 cycles, one cycle every 21 days.
Esophagectomy
Prior to each surgical procedure, the department engaged in comprehensive discussions and deliberations to ascertain and establish the most suitable course of action. Minimally invasive Ivor-Lewis (intrathoracic anastomosis) or McKeown (neck anastomosis) esophagectomy, including two field extensive lymphadenectomies, was performed according to the tumor location. The resection length should be at least 5cm from the tumor origin according to prechemotherapy by endoscopy. The surgeries will be performed by surgeons with rich experience. Minimally invasive esophagectomy, can be performed using the da Vinci surgical robot, thoracoscope, or laparoscope, or by using an open approach, as judged appropriate by the surgeon.
Sample
Blood, Tumour will be Collected from participant. Fate of sample is Destruction after use. 5 ml of peripheral blood was collected the day before each of the immunotherapy sessions and after surgery. Tumour sample will be collected before neoadjuvant therapy and during surgery.
