ctDNA-MRD Guided Escalation of Ivonescimab and Docetaxel in Advanced NSCLC With Long-Term Responses to First-line Immunotherapy (CR1STAL-Adaptive)

The CR1STAL-Adaptive study is a randomized, open-label, phase II multicenter interventional trial designed to evaluate the safety and efficacy of Ivonescimab (PD-1/VEGF bispecific antibody) combined with docetaxel versus standard treatment in patients with advanced NSCLC who have achieved long-term benefit from first-line immune checkpoint inhibitors (ICIs), but are ctDNA-MRD positive. Building upon insights from previous CR1STAL study (NCT05198154), the CR1STAL-Adaptive study supports the development of precision-guided, adaptive treatment strategies to delay progression and improve outcomes in NSCLC patients with a long-term response to immunotherapy. It represents a step forward in integrating dynamic molecular monitoring with individualized intervention strategies in the era of immunotherapy.

The Impact of Emotional Stress on Immunotherapy Outcomes in Liver Cancer Patients: A Multi-Cohort Study

The goal of this observational study is to learn if emotional distress affects how well liver cancer treatment works in people receiving immunotherapy. Emotional distress means feeling anxious or depressed. The study aims to answer whether having emotional distress before treatment or changes in emotional distress during treatment affect how well immunotherapy works to treat liver cancer. Researchers will compare participants with and without emotional distress to examine differences in how long the cancer stays under control, treatment response, and overall survival time. Study participants will complete mood and quality of life questionnaires, meet with mental health specialists for emotional assessments, undergo regular blood tests to measure stress hormones, have routine medical check-ups and scans to monitor their cancer status, and be followed for up to 3 years. The study includes three groups of people with liver cancer: those starting immunotherapy for cancer that cannot be removed by surgery, those receiving immunotherapy after surgery, and those receiving immunotherapy before surgery. To be eligible for participation, individuals must be 18 years or older, diagnosed with liver cancer, about to start immunotherapy treatment, and able to complete mood questionnaires.

Immune Checkpoint Inhibitors (ICIs) Retreatment in Second-line Treatment of Advanced Gastric Cancer: a Retrospective, Real-world Study

This is a single-center, retrospective, observational, real-world study. We collected general and clinical data of patients with advanced gastric cancer who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to July 2024.

Neoantigen Vaccines in Esophageal Squamous Cell Carcinoma

The aim of this clinical trial is to evaluate the efficacy and safety of consolidation therapy with a neoantigen-loaded dendritic cell vaccine (NeoDC-Vac) following radical chemoradiotherapy or chemoradiation-immunotherapy in patients with locally advanced, unresectable ESCC. The primary endpoint of the study is the OS rate. Secondary endpoints include OS, PFS, adverse events, CR rate, and quality of life (QoL) of patients. Exploratory endpoints involve the assessment of biomarkers such as TMB, PD-L1, and ctDNA. The key questions this study aims to answer are: -Can the combination of (ICIs and NeoDC-Vac as maintenance therapy improve OS and QoL in patients with locally advanced, unresectable ESCC following radical treatment? Can this novel approach provide an effective treatment option for these patients? Participant Procedures: 1. Endoscopic examination at West China Hospital. Baseline fresh tumor tissue collection for NGS in neoantigen vaccine group. 2. Screening assessments, informed consent, and random assignment to experimental or control group. Experimental Group\*\*: Neoantigen-loaded vaccine + standard ICIs as maintenance therapy. Control Group\*\*: Standard ICIs as maintenance. One cycle per month for one year. 3. Tumor tissue NGS, ctDNA analysis, TIME evaluation, T cell response profiling. All costs covered by research funding. 4. After completing the full treatment regimen, participants will be monitored with regular follow-up visits by healthcare professionals to assess ongoing health outcomes and safety.
