AI-Driven Digital Twin and Drug Simulation for Esophageal Cancer (ESCA-DT)

2026년 8월 10일 업데이트: YanZheng,MD, Henan Cancer Hospital

Construction of Artificial Intelligence Model for Esophageal Cancer Digital Twin Patients and Drug Efficacy Simulation Verification Based on Supercomputing Platform and Multi-Omics Data

This study aims to integrate multi-omics data (genomics, transcriptomics, proteomics) from esophageal cancer patients with artificial intelligence and digital twin technology to construct personalized virtual patient models that precisely simulate individual responses to targeted therapies. Through a drug simulation platform, this study will rapidly screen potential effective drug combinations and optimize dosage and treatment regimens. The project attempts to replace portions of traditional clinical trials with virtual clinical trial technology, substantially shortening the R&D cycle, reducing costs, and effectively addressing the complexity of individualized treatment. Specifically, this study will conduct a head-to-head virtual clinical trial parallel to a real-world investigator-initiated trial (IIT) in patients with locally advanced esophageal squamous cell carcinoma, comparing the efficacy predictions from the virtual model with actual clinical outcomes. The ultimate goal is to explore the application of large-scale AI models in esophageal cancer targeted therapy, provide personalized treatment recommendations, and advance the implementation of precision medicine in esophageal cancer.

상세 설명

This is a prospective, single-center, observational cohort study integrating virtual clinical trial technology. The study is designed to validate the feasibility and accuracy of AI-driven digital twin models for predicting treatment responses in esophageal cancer patients.

Background and Rationale:

China accounts for approximately half of the global esophageal cancer cases, with the highest incidence rates concentrated in the Taihang Mountain region, particularly Henan Province. Despite advances in early diagnosis and treatment, tumor heterogeneity and individual patient variability continue to limit therapeutic efficacy, especially in advanced-stage patients. Virtual clinical trial technology, which uses supercomputing to simulate drug efficacy and safety across virtual patient populations, offers a promising approach to accelerate drug screening while reducing costs and ethical constraints associated with conventional trials.

Study Population:

The study will enroll 400 patients with locally advanced (T1N1-3M0 or T2-3N0-3M0) thoracic esophageal squamous cell carcinoma (8th UICC-TNM staging), aged 18 to 75 years, with ECOG performance status 0-1 and adequate organ function. All patients must have received no prior antitumor therapy for esophageal cancer and be candidates for R0 resection.

Virtual Patient Modeling:

For each enrolled patient, peripheral blood samples will be collected prior to treatment initiation for whole-exome sequencing (WES). Multi-omics data will be integrated with clinical information to generate a personalized digital twin for each participant. These virtual patients will undergo simulated treatment and efficacy prediction using the drug efficacy prediction model.

Treatment Arms:

  • Experimental Group (n=200): Neoadjuvant immunochemotherapy consisting of toripalimab (JS001) 240 mg IV on day 3, paclitaxel 175 mg/m2 IV on day 1, and cisplatin 75 mg/m2 IV on day 1, administered in 21-day cycles for 2 cycles, followed by surgery and postoperative toripalimab maintenance therapy (240 mg Q3W for up to 8 cycles or 6 months).
  • Control Group (n=200): Neoadjuvant chemotherapy consisting of paclitaxel 175 mg/m2 IV on day 1 and cisplatin 75 mg/m2 IV on day 1, administered in 21-day cycles for 2 cycles, followed by surgery.

Surgery and Follow-up:

Surgery will be performed 4-8 weeks after the last neoadjuvant cycle using McKeown minimally invasive or open esophagectomy with two-field lymphadenectomy. Postoperative surveillance includes contrast-enhanced CT of the chest and upper abdomen and contrast-enhanced CT of the neck, performed every 3 months for 2 years, then every 6 months until year 5. Adverse events will be monitored throughout and graded according to CTCAE v5.0.

Outcomes:

The primary endpoint is Event-Free Survival (EFS), defined as the time from randomization to the first occurrence of inoperability, distant metastasis, local recurrence, or death from any cause, whichever occurs first. Secondary endpoints include pathological complete response (pCR) rate, overall survival (OS), disease-free survival (DFS), objective response rate (ORR), R0 resection rate, major pathological response (MPR) rate, quality of life (EORTC QLQ-C30 and QLQ-OES18), and safety (incidence of adverse events per CTCAE v5.0).

Virtual Clinical Trial Component:

Parallel to the real-world IIT, a virtual clinical trial will be conducted using the AI-powered drug simulation platform. The virtual predictions will be compared with actual clinical outcomes to evaluate the accuracy and reliability of the digital twin model. The study will assess the concordance between predicted and observed responses, including sensitivity, specificity, positive predictive value, and negative predictive value of the model.

Statistical Analysis:

Based on the primary endpoint EFS, a sample size of 400 patients (1:1 allocation) is planned, providing 90% power at a two-sided alpha level of 0.05 to detect a hazard ratio of 0.68, assuming a median EFS of 20 months in the control group. Efficacy analyses will be performed on the intention-to-treat (ITT) population using stratified log-rank tests and Cox proportional hazards models. Kaplan-Meier methods will estimate survival distributions. Safety analyses will be conducted on the safety set.

Study Duration:

The study is anticipated to enroll participants from January 2026 to June 2028, with final data collection completed by December 2028.
