NCT03038568
The purpose of the study is to see how measurements of tumor differences vary with slight changes in CT scan parameters. Reproducible radiomic features can be extracted for abdominal tumors, and specifically colorectal liver metastases, imaged with clinical CT scanners even in the setting of variable scan parameters and variable contrast timing. Participants will be consented to undergo an additional CT of their abdomen.
NCT04245865
This double blind, randomized phase II trial will investigate whether the addition of tocotrienol will improve the effect and lower the toxicity of standard chemotherapy and bevacizumab. Half of the patients will receive tocotrienol and the other half placebo. Treatment is planned for a period of maximum six months and will be discontinued earlier in case of progression or unacceptable toxicity.
NCT06634875
This study will enroll patients with colorectal cancer that is locally advanced or metastatic. The tumor must be microsatellite stable (MSS), have a tumor mutational burden that is high (TMB-H) and be kras mutated. Patients must have been treated with available approved treatments already. In this study the investigators are testing a new type of immunotherapy, the potent IL-1 inhibitor isunakinra to be added to already approved immunotherapy (PD-1/PD-L1 inhibitor) in an attempt to get this treatment to work in this treatment resistant type of tumor.
NCT07486492
This research protocol outlines an exploratory study on the combination of early-life fecal microbiota transplantation (yFMT) with immunotherapy and chemotherapy in patients with microsatellite stable metastatic colorectal cancer (MSS mCRC). The single-center, single-arm study aims to assess the safety of yFMT in conjunction with immunotherapy and chemotherapy, with a secondary focus on exploring its efficacy and impact on the patients' immune microenvironment. The study will enroll 10 patients aged 18-75 who have progressed after first-line chemotherapy and targeted therapy. The intervention involves six sessions of yFMT every two weeks, alongside PD-1 inhibitor immunotherapy and FOLFIRI chemotherapy. The primary endpoints are the incidence of serious adverse events (SAEs), treatment-related adverse events (TRAEs), and intervention adjustments due to adverse events, while secondary endpoints include progression-free survival (PFS), objective response rate (ORR), and overall survival (OS). The study is expected to last two years from initiation to data analysis completion, and it will be conducted at the Gastrointestinal Tumor Surgery Department of the First Affiliated Hospital of Xiamen University.
NCT05759728
This study aims to determine the safety and best response of treatment with CNA3103 (Leucine-rich repeat-containing G protein-coupled receptor 5 \[LGR5\]-targeted, Autologous Chimeric Antigen Receptor (CAR) -T Cells), for participants with Metastatic Colorectal Cancer. Participants may undergo a pre-screening biopsy procedure to determine expression of LGR5. Participants will undergo screening procedures, including leukapheresis (collection of T cells) and lymphodepletion (chemotherapy), up to 47 days prior to CNA3103 dosing. Participants will receive a single Intravenous dose of CNA3103. Expansion cohorts will open after determination of the maximum tolerated dose and recommended phase 2 dose in the dose escalation stage. Participants will be followed up, monitored and will attend study visits for safety and research related tests and procedures for 2 years until disease progression, unacceptable toxicity or intolerable adverse event/s, death or withdrawal of consent.
NCT07328087
This is an early phase I, single-arm, open-label clinical study designed to evaluate the safety, tolerability, and feasibility of COLONYVAQ-CRC, a physics-aware, quantum-classical AI-guided personalized neoantigen peptide vaccine, administered in combination with standard adjuvant oxaliplatin-based chemotherapy (mFOLFOX6 or CAPOX) and nivolumab 3 mg/kg in patients with completely resected stage III microsatellite-stable (MSS) / proficient mismatch repair (pMMR) colorectal cancer. An initial safety cohort of 12 patients will be enrolled and closely monitored for toxicity attributable to the experimental vaccine preparation. If, among these 12 patients, fewer than 3 develop experimental-preparation-related toxicity greater than grade 2 and no patient develops experimental-preparation-related grade 4 toxicity, the study will expand to enroll a total of 50 patients. Primary objectives focus on safety and tolerability of the combination regimen. Secondary and exploratory objectives characterize neoantigen-specific immune responses, ctDNA dynamics, T-cell receptor (TCR) clonotype evolution, tumor immune microenvironment features, and preliminary disease control (disease-free survival and overall survival) to inform subsequent phase II design.
NCT06283134
This is a phase I, open-label clinical study of BioTTT001 in combination with Toraplizumab and Regorafenib in patients with liver metastases from colorectal cancer.
NCT06332079
The aim of this study is to assess the efficacy of 166Ho-TARE followed by maintenance therapy with fluoropyrimidine and anti-EGFR or bevacizumab in liver-limited unresectable colorectal cancer patients, in terms of progression free rate 9- and 8-months for cohort A and B, respectively.
NCT07213570
The investigators hypothesize that patients with mCRC RAS-mutant eligible for a second line treatment with good prognostic features, identified as single metastatic site, long progression free survival (PFS) in first line treatment, might benefit from a personalized approach, with less intensive treatment with regorafenib as part of a continuum-of-care strategy aimed at ensuring quality of life and extending survival.
NCT04684862
This is a single-site, open-label continued access study/treatment protocol under a treatment IDE. In addition to treating patients, the primary objective of this study is to assess the safety of using the Medtronic SynchroMed II programmable pump combined with the Intera tapered catheter for hepatic artery infusion (HAI) of a standard chemotherapy (FUDR) drug for adults with a clinical or biopsy-proven diagnosis of colorectal cancer metastatic to the liver or intrahepatic cholangiocarcinoma. After successful implantation, the combined pump and catheter system will be evaluated using a nuclear scan in the postoperative period, which is standard procedure to confirm that the pump is functioning prior to HAI of FUDR. Monitoring for safety will include a record of residual pump volume when it is emptied (every 2-12 weeks depending on whether the pump is being used for chemotherapy infusion) to determine if the pump is still working and surveillance of routine cross-sectional imaging (usually every 2-6 months) for any sign of a pump or catheter problem. Patients will be monitored for the safety of the pump/catheter combination for up to 5 years or pump removal/study withdrawal.
NCT06889610
This study focuses on the treatment of liver metastases from three common cancers: colorectal cancer, triple-negative breast cancer and melanoma. Currently, there are limitations in the treatment of liver metastases of these cancers. Multimodal thermophysical ablation therapy can reshape the tumor microenvironment, release neoantigens, and act as an in-situ vaccine. On this basis, the combination of multimodal ablation with immunotherapeutic drugs such as pucotenlimab will be explored. The efficacy and safety of this combination therapy in patients with liver metastases of solid tumors will be investigated, with the expectation of breaking through the existing treatment limitations.
NCT05200442
Doctors leading this study hope to learn about the safety of combining the study drug VS-6766 with another drug called cetuximab in colorectal cancer. This study is for individuals who have advanced colorectal cancer and their cancer has progressed while getting previous treatment or individuals who cannot take/tolerate previous treatments. If you choose to participate, your time in this research will last up to 24 months.
NCT04031872
Part I of this study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of LY3200882/capecitabine as second line treatment in patients with 5-FU or capecitabine resistant CRC. Part II is designed to obtain proof of principle of the LY3200882 plus capecitabine combination in patients with chemo-resistant CRC. The combination of LY3200882 plus capecitabine will be given as second line therapy in the phase II part of this study. Patients with chemotherapy resistant activated TGF-β signature-like tumors will have received a fluoropyrimidine (5FU or capecitabine) in the first line of chemotherapy, usually combined with oxaliplatin and, depending upon local hospital preferences or national guidelines, also bevacizumab, or cetuximab/panitumumab if the tumor is KRAS wild type. Addition of LY3200882 to capecitabine should thus result in reversal of unresponsiveness, which is the first step in exploring this concept in the clinic. Capecitabine can be used as single agent in advanced CRC and is thus attractive for this study concept. If proof of principle is achieved also other tumor types can be explored with this genetic makeup, such as non-small cell lung cancer (NSCLC) in second line of treatment after platinum doublet therapy in first line, usually cisplatin/carboplatin-pemetrexed in non-squamous and cisplatin/carboplatin-gemcitabine or cisplatin/carboplatin-paclitaxel in squamous type NSCLC.
NCT04874207
Regorafenib has demonstrated a significant benefit in overall survival in metastatic colorectal cancer (mCRC) patients. However, more than 50% of patients had severe adverse events (grade 3-4), leading to temporary or definitive discontinuation of treatment. The RePERSO study proposes to adapt the regorafenib dose regimen taking into account firstly the measurement of sum of metabolites M-2 and M-5 and secondly the occurrence of toxicity during treatment. This treatment personalization through therapeutic drug monitoring pharmacological dosing optimization strategy aims at validating the proof of concept of regorafenib therapeutic drug monitoring and at improving the benefit in OS in patients, using the previously defined Csum therapeutic range.
NCT07061210
To evaluate the safety and efficacy of HRS-2189 combined with Adebrelimab and BP102 in the treatment of metastatic colorectal cancer
NCT03657641
This phase I/II studies the side effects and best dose of regorafenib when given together with pembrolizumab in treating participants with colorectal cancer that has spread to other places in the body. Drugs used in chemotherapy, such as regorafenib, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Giving regorafenib and pembrolizumab may work better at treating colorectal cancer.
NCT07050394
This study is a single-arm, open-label, exploratory clinical trial. Building on the previous dose-escalation trial, this dose-expansion trial aims to evaluate the safety and tolerability of intravenous monotherapy with CD-GA-102 or its combination with immunotherapy and other systemic treatments in patients with unresectable locally advanced or metastatic colorectal cancer, and to preliminarily explore its efficacy in treating colorectal cancer.
NCT03364621
This is a prospective study investigating the disease course of patients with colorectal cancer that have had their cancer spread to their liver. The aim of this study is find potential biomarkers for disease recurrence and therapeutic targets for prognostic information.
NCT06414304
Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Microsatellite instability or mismatch repair deficiency occurs in 20% of CRC, and is predominantly found in non-metastatic tumors. The success of the CheckMate 142 and KEYNOTE-177 clinical trials has shifted the treatment paradigm of the MSI/dMMR CRC, which has led to the adoption of immune checkpoint inhibitors (ICI) by international treatment standards. However, despite the encouraging effects of ICI, up to 30% of patients are resistant to treatment and exhibit rapid disease progression shortly after starting ICI. On the other hand, around 30% of patients treated with ICI demonstrate prolonged responses to the treatment with a duration of response of over 40 months. Furthermore, for \~10% of patients, treatment with ICI results in pseudo-progression - a phenomenon of a short-term increase followed by the decrease of the tumor volume. Currently, the mechanisms and biomarkers associated with the response or resistance to ICI in MSI-positive CRC are largely unknown. Select studies suggest that BRAF mutations (specifically, BRAF p.V600E) might negatively affect the patients' progression-free survival following ICI, however, these data are premature. The primary hypothesis is that the clonal heterogeneity and the evolution of MSI status of MSI-positive CRC will play a role in the development of ICI treatment resistance. The primary objective of the study is to investigate the dynamics of MSI status in serial liquid biopsy samples from patients with MSI-positive tumors receiving ICI.
NCT07012954
The objective of this randomized controlled clinical trial is to evaluate the efficacy of ctDNA-guided rechallenge with cetuximab plus trifluridine/tipiracil compared with bevacizumab plus trifluridine/tipiracil in patients with treatment-refractory, RAS/BRAF wild-type metastatic colorectal cancer.
