Filter by:Dose escalation clinical trial: To explore the dose limiting toxicity (DLT) of irinotecan liposome injection combined with oxaliplatin +5-FU/LV+ bevacizumab in first-line treatment of patients with advanced metastatic colorectal cancer, and to estimate the maximum tolerated dose (MTD) of combined administration. Expansion clinical trial: To evaluate the safety and efficacy of irinotecan liposome injection combined with oxaliplatin +5-FU/LV+ bevacizumab or cetuximab in first-line treatment of patients with advanced metastatic colorectal cancer. Exploratory analysis of ctDNA changes and genetic mutations in patients at baseline.
Fruquintinib, as a standard treatment for refractory metastatic colorectal cancer (mCRC), has attracted increasing research efforts to explore its innovative strategies in combination with immunotherapy and chemotherapy because of its multi-target mechanism which enhances the sensitivity of the immune system and chemotherapy, aiming to further improve the survival benefits for mCRC patients. Trifluridine/tipiracil (TAS-102) is also a standard treatment for mCRC. This study aims to investigate the safety and effectiveness of the combined use of these two drugs in mCRC.
The dual immunotherapy regimen significantly outperformed previous chemotherapy or immunomonotherapy for MSS type advanced CRC in two key efficacy indicators, ORR and PFS. Researchers have also conducted in-depth analysis of patient transcriptomics, immune microenvironment characteristics, and other related information, which is expected to guide more accurate immune combination therapy for CRC in the future. Our team plans to conduct a multicenter, prospective, single arm clinical trial in patients with RAS mutant MSS unresectable metastatic colorectal cancer, with a focus on observing the 1-year progression free survival rate of the combination of two chemotherapy drugs, bevacizumab and Cadonilimab, as well as ORR, perioperative safety, and long-term survival.
The goal of this study is to investigate the value of MR elastography-based SII as a means of detecting HGP noninvasively in patients with pathology-proven CRLM. MRE will provide a direct measure of tumor-liver adhesion to investigate the relationship between imaging findings and pathophysiological changes in the Liver.
Fruquintinib is an oral tyrosine kinase inhibitor (TKI), which improves progression-free survival (PFS) and overall survival (OS) in patients with refractory metastatic colorectal cancer (mCRC). Here, we explore the real-world treatment patterns of fruquintinib in the third- or late-line setting for mCRC in six centers in China.
This research study is a randomized controlled trial that will observe changes in microbiome activity, changes in chemotherapy toxicity, and any changes in treatment outcomes between two groups of participants undergoing chemotherapy with either early-stage or metastatic colorectal cancer. The names of the study groups involved in this study are: - Exercise - Waitlist Control
In mCRC, response to second-line chemotherapy is limited, and few treatment options are available. It is urgent to design an optimal second-line treatment regimen to improve the response rate and prolong the survival of patients with mCRC. Several studies preliminarily demonstrated that irinotecan, TAS-102 plus bevacizumab regimen could bring promising efficacy with a tolerable safety profile for patients with mCRC as a second-line treatment. This phase I/II study was aimed to determine the recommended phase II dose (RP2D) of the combination of TAS-102, irinotecan, and bevacizumab for future clinical trials in patients with mCRC refractory to both fluoropyrimidine and oxaliplatin and to evaluate its safety and preliminary efficacy.
The aim of this study is to evaluate the efficacy and safety of short course radiotherapy followed by fruquintinib combined with Sintilimab as the first-line treatment of advanced mCRC compared to bevacizumab combined with capecitabine in patients unfit for intensive therapy.
A real-world study of trifluridine/tipiracil containing regimen for the treatment of patients with metastatic colorectal cancer. A total of 200 patients planned to be enrolled.
Colorectal cancer (CRC) is the 3rd most common cancer worldwide and accounts for ~14,000 new diagnoses and ~5,000 deaths in the Netherlands yearly (1.9 million and 935 thousand on a global level). Large scale transcriptional profiling of primary CRC tumors has revealed the presence of four distinct consensus molecular subtypes (CMSs). The CMS4 subtype is associated with a poor prognosis, especially in early CRC, and may benefit less from several standard systemic treatments (e.g. oxaliplatin, 5-fluorouracil, cetuximab), while being relatively sensitive to irinotecan. This is relevant as in the metastatic setting often the first choice first-line systemic therapy regimen is oxaliplatin and not irinotecan-based. Furthermore, tumor cells can acquire a CMS4 phenotype following exposure to chemotherapy, which may contribute to therapy resistance. CMS4 accounts for ~25% of all early-stage CRC patients and is more prevalent in advanced disease stages (~40% in stage IV CRC). Currently available CMS4 diagnostic tests require tumor tissue samples. The interpretation of biopsy-based CMS4 diagnosis is however complicated by large intra- and inter-lesion heterogeneity of CMS4 status. Extensive biopsy protocols could address the problem of CMS4 heterogeneity but are challenging in routine clinical practice. The development of CMS4-targeted therapy strategies therefore requires a more robust and clinically applicable diagnostic test for comprehensive quantitative assessment of CMS4 status of all lesions - primary and metastatic - in individual cancer patients. A promising solution for such a diagnostic test is to use a radiotracer that enables the quantitative assessment of CMS4 in vivo by whole body molecular imaging. This technique is particularly suited to assess biomarkers with heterogeneous expression: for diagnostic purposes, as a companion diagnostic for (targeted) therapies, or as part of a 'theranostic' strategy where patient selection using the diagnostic radiotracer is followed by treatment with the same tracer labeled to a therapeutic compound. Radiolabeled fibroblast activating protein inhibitor (FAPI) is an emerging diagnostic radiotracer that allows the comprehensive whole-body, whole-tumor assessment of fibroblast activation protein (FAP) expression in humans with a very low background uptake also at frequent CRC metastatic sites including the liver. FAP is an excellent candidate molecular imaging target for CMS4, as it is highly expressed on cancer-associated fibroblasts (CAF) that are abundantly present in this CRC subtype. Indeed, the investigators found that FAP gene-expression measured in tumor biopsies - as a single marker - accurately discriminates CMS4 from other CRC subtypes (area under the receiver operating characteristic curve (AUROC): 0.91; 95% confidence interval (CI): 0.90-0.93). The FoCus study will aim to take a next step by relating in vivo assessed FAP protein-expression by [18F]-ALF-FAPI-74 positron emission tomography (PET) / computed tomography (CT) to CMS4 status in patients eligible for colorectal liver metastatectomy as a first proof of concept. Ultimately this will contribute to the development of a diagnostic tool for the comprehensive assessment of CMS4 load in patients with (metastatic) CRC by using [18F]-ALF-FAPI-74 PET/CT molecular imaging, to guide CMS4 subtype-directed therapy decisions.
