Based on ctDNA-MRD Guided Adjuvant Treatment Escalation After Definitive Chemoradiotherapy for Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma: a Study on Safety and Efficacy

Numerous studies have confirmed that ctDNA-MRD detection technology based on peripheral blood can identify minimal residual disease (MRD) following surgery and other curative treatments, indicating a higher risk of recurrence. Multiple exploratory studies in esophageal cancer have demonstrated that patients who are ctDNA-MRD positive after definitive chemoradiotherapy (dCRT) exhibit poorer progression-free survival (PFS) and a higher risk of recurrence. Furthermore, the recent NEXUS-1 translational study confirmed that 66.7% of unresectable patients achieved the goal of conversion surgery after receiving definitive chemoradiotherapy combined with immunotherapy. Notably, patients who were ctDNA-MRD positive after chemoradiotherapy had a significantly worse prognosis. These findings suggest that ctDNA-MRD status after chemoradiotherapy has prognostic stratification value and that consolidative immunotherapy is effective. Based on these previous discoveries, this study aims to investigate the safety and efficacy of an escalated treatment strategy involving immunotherapy combined with chemotherapy for high-risk populations after definitive chemoradiotherapy for esophageal cancer, guided by personalized MRD detection results.

Minimal Residual Disease Used in Predicting Therapeutic Efficacy in Metastatic Hormone-sensitive Prostate Cancer

This study is a prospective, single-center, observational study of patients with newly diagnosed metastatic hormone-sensitive prostate cancer (mHSPC). Minimal residual disease (MRD) detection is used to investigate the actual efficacy responses of mHSPC patients with different gene mutation characteristics to treatment regimens. Factors influencing efficacy are further analyzed to provide a basis for the precise clinical diagnosis and treatment of mHSPC patients.

Adaptive Adjuvant Sintilimab Therapy Guided by MRD (ADAPT Lung)

This is a multicenter, prospective, open-label Phase II study designed to evaluate the safety and efficacy of adjuvant sintilimab therapy guided by minimal residual disease (MRD) in patients with Stage II-IIIB non-small cell lung cancer (NSCLC) who have not achieved a pathological complete response (non-pCR) after neoadjuvant immunotherapy combined with chemotherapy. The study is being conducted at the Third People's Hospital of Chengdu and the Guangdong Provincial People's Hospital.

A Study of Tumor-Agnostic MRD Detection in Stage III Colorectal Cancer

This observational study aims to evaluate the predictive performance of various omics-based methods for detecting minimal residual disease (MRD) in stage III colorectal cancer. The study involves the collection of blood samples from patients who have accepted surgery for colorectal cancer. Blood samples will be analyzed using both tumor-informed and tumor-agnostic approaches to detect circulating tumor DNA (ctDNA). The study will compare the sensitivity of these methods and assess their correlation with recurrence risk. The findings aim to inform the development of optimal MRD detection strategies, ultimately providing a robust molecular basis for personalized treatment decisions.

A Clinical Study on Minimal Residual Disease in Patients With Systemic Light Chain Amyloidosis

Before effective treatment, the prognosis of patients with AL amyloidosis is very poor, with a median survival of approximately 12 months. In recent decades, with the development of new drugs, the treatment paradigm for AL amyloidosis has undergone significant changes, and the prognosis has improved dramatically. Achieving very good partial response (VGPR) or even complete response (CR) can lead to higher organ response and longer survival. However, not all patients who achieve ≥VGPR reach organ response, which may be related to the presence of small residual plasma cell clones in these patients. The ongoing production of monoclonal light chains deposits into tissues and organs, causing continuous damage, making organ response difficult. With the development of new drugs, the rate of hematologic CR has continuously increased, and the advancement of minimal residual disease (MRD) detection technologies in recent years has led to increasing attention to MRD in AL amyloidosis research. Therefore, in this era of advancing new drugs, MRD negativity may become a higher clinical treatment goal for AL amyloidosis, further improving long-term prognosis for patients. Our department plans to conduct a single-center, prospective clinical study aimed at exploring the MRD status in patients who achieve hematologic CR after first-line induction chemotherapy (Dara-CyBorD), and further investigating whether autologous stem cell transplantation in MRD-positive CR patients who meet transplant criteria can further improve organ response, progression-free survival, and overall survival.

Treatment of High-risk Newly Diagnosed Multiple Myeloma With Minimal Residual Disease Detection

The goal of this study is to evaluate sustained MRD negativity for one year in DKRD induction \& consolidation therapy +/- ASCT in newly diagnosed high-risk multiple myeloma patients. It aims to evaluate the efficacy and safety of the combination regimen of Daratumumab in combination with carfilzomib, lenalidomide, and dexamethasone (DKRD) +/- ASCT for the treatment of patients with newly diagnosed high-risk multiple myeloma. Participants will receive bortezomib based induction therapy for one cycle, and then DKRD induction for 3 cycles(+ASCT), DKRD consolidation for 2-4 cycles, and DKR maintenance treatment(adjusted according to MRD negativity after consolidation therapy)

Observational Clinical Study on Role of MRD in Predicting Local Therapy in Oligometastatic Breast Cancer

This is an observational clinical study of MRD as a predictor of local treatment in patients with oligometastatic breast cancer. The aim of the study is to assess the correlation between MRD levels and prognosis in patients with oligometastatic breast cancer who have undergone local treatment in order to identify the population that would benefit from local treatment and to develop an individualised treatment plan. Subjects will agree to participate in this study and will be asked to collect as much medical history and demographic information as possible prior to enrolment to confirm that they meet the inclusion/exclusion criteria, and that they will undergo imaging and MRD testing prior to their first study treatment. Furthermore, subjects will undergo tumour imaging and MRD testing every 3 months (±7 days) after MRD treatment for the duration of the study, with additional investigations or more frequent tumour imaging evaluations as clinically indicated during the study.

Adaptive Treatment for Acute Myeloid Leukemia Based on D14 MRD Results

This is a prospective, single-arm, multi-center clinical trial to evaluate the efficacy and safety of selinexor in combination with azacitidine and venetoclax for untreated acute myeloid leukemia based on MRD results on day 14 of the first cycle.

Adjuvant Treatment Based on MRD for EGFR Mutant NSCLC

A prospective, multicenter clinical study designed to explore the efficacy of postoperative adjuvant EGFR-TKIs therapy based on MRD status in patients with stage IB-IIIB EGFR-mutant non-squamous non-small cell lung cancer (non-squamous NSCLC). Primary endpoints include 3-year Disease-Free Survival rate (3y-DFS) and median disease-free survival (mDFS).
