Neoadjuvant Therapy of Anlotinib Combined With Toripalimab and Chemotherapy for Resectable Esophageal Carcinoma

Anlotinib in Combination With Toripalimab and Chemotherapy for Neoadjuvant Treatment of Resectable Esophageal Squamous Cell Carcinoma: a Phase II Clinical Study

The purpose of this study is to explore the effectiveness and safety of the combination of Anlotinib, Toripalimab, and albumin-bound paclitaxel with cisplatin for neoadjuvant therapy in resectable esophageal squamous cell carcinoma. The study aims to improve the pathological complete response rate (pCR), R0 resection rate, and disease-free survival (DFS) in patients undergoing esophageal cancer surgery. The findings of this study will provide guidance and new options for the treatment of locally advanced esophageal cancer patients.

Study Overview

• Status: Not yet recruiting
• Conditions: Neoadjuvant Therapy; Esophageal Carcinoma
• Intervention / Treatment: Drug: Toripalimab; Drug: Anlotinib hydrochloride; Drug: Albumin paclitaxel; Drug: Cisplatin

Detailed Description

Both anti-angiogenic therapy and immune checkpoint inhibitors have shown preliminary efficacy and safety data in the field of neoadjuvant therapy for esophageal cancer. However, there is currently no available data on the combination of immune checkpoint inhibitors, anti-angiogenic therapy, and chemotherapy in neoadjuvant therapy for esophageal cancer. Based on the favorable survival benefits of this combination in first-line and second-line treatments for multiple tumors, we aim to explore another neoadjuvant treatment approach - adding anti-angiogenic agents to immune checkpoint inhibitor-based neoadjuvant therapy, providing a new perioperative treatment strategy for esophageal cancer.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
R0 resection rate	Residual tumor rate	Immediately after the surgery
Objective response rate (ORR)	ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1	Up to 36 month
Disease control rate (DCR)	DCR is defined as the percentage of participants in the analysis population who have a CR, PR or stable disease (SD) per RECIST 1.1.	Up to 36 month
Disease-free survival (DFS)	Survival without local or systemic recurrence	3(5) years after last patient enrolled
Overall survival (OS)	Overall survival is defined as the duration from date of enrollment to the date of death from any cause.	Up to 36 month

Change From Baseline in HRQoL Score Using EORTC Quality of Life Questionnaire-Oesophageal Module (QLQ-OES18)	The EORTC QLQ-OES18 is a disease-specific questionnaire to assess measurements specific to esophageal cancer. It contains 18 items and is based on four subscales-dysphagia, eating, reflux and pain. All items are scored using a four-point scale that offers these response choices: 1=not at all, 2=a little, 3=quite a bit, 4=very much. A higher score indicates worse level of symptoms. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in HRQoL QLQ-OES18 score in participants will be presented.	Up to 36 month
