Filter by:To describe the accuracy of FAPI PET/CT in the detection of regional lymph node metastases in patients with colorectal cancer in comparison with standard diagnostic imaging and (in operated patients) histopathology, aiming to provide early evidence of the diagnostic value of FAPI PET/CT.
This Phase Ib/IIa study has been designed according to a 3+3 dose escalation/dose expansion design. A dose expansion will be conducted at both the intermediate and high dose levels, if tolerated, with the purpose of generating additional and more robust safety and preliminary efficacy data. No control arm was included, as the target patient population of this study consists of patients in whom the overall survival is less than 6 months and treatment options are very limited and often poorly tolerated, making unlikely that the study results can be significantly biased.
In summary, our study demonstrated the methylation sites of SFRP1 gene promoter in patients with colorectal cancer and adenoma and found SFRP1_16_17_18 CpG site was good performance as a diagnostic marker of colorectal cancer.
Colonoscopy is an exam which can be responsible for pain and discomfort for the patient. Therefore colonoscopy is performed most of the time under general anaesthesia. Moreover, drug-induced sedation comes with adverse effects especially among fragile patients. Besides, monitoring patients during and after sedation is both logistically demanding and costly. Virtual reality offers immersive and three dimensional experiences that distract the attention and might improve patients comfort. The aim of the study is to investigate the use of virtual reality during colonoscopy versus general anaesthesia.
This study is a prospective single-arm phase II clinical study. Advanced gastric and colorectal tumor patients with FGFR 1-3 alterations who have failed standard therapy will be enrolled in this study once they have signed the informed consent form (ICF) and been identified as eligible in screening. The patients will receive 13.5 mg of pemigatinib once a day (QD) orally following a 2-week administration/1-week interruption regimen. They will be dosed until disease progression or intolerable toxicity. During treatment, clinical tumor imaging evaluation will be performed according to RECIST v1.1 every 6 weeks (± 7 days) and then every 9 weeks (± 7 days) after week 48. Safety will be assessed according to NCI-CTCAE 5.0.
Colorectal Cancer (CRC) is a leading cause of cancer-related death. Around 30% of patients present with advanced disease and 50% of those that attempt curative surgery will eventually relapse. The potential synergism of combining PARP inhibitor and PD-L1 is based on the hypothesis that pharmacological inhibition of PARP by olaparib will result in enhanced immunogenicity which can be further enhanced with an immune checkpoint inhibitor such as pembrolizumab. This may occur through a number of mechanisms, such as increased production of cytokines and chemokines that have the potential to promote antitumour immunity, upregulation of surface receptors which render tumour cells more visible to detection by cytotoxic T cells thereby leading to death of tumour cells and release of neoantigens, that help promote antigen presentation and immune priming. This hypothesis is supported by preclinical studies in mouse models of cancer, demonstrating that administration of a PARP inhibitor to sensitive tumour types resulted in increased T cell infiltration and immune activation within tumours. The primary hypothesis is that Olaparib and pembrolizumab combination will lead to an increase in objective response rate in patients with refractory metastatic colorectal cancer (mCRC) with DNA homologous-recombination-repair deficiency (HRD) from 1.5% in benchmark studies to up to >10%. The primary objective of the study is to determine the objective response rate (ORR) of pembrolizumab in combination with olaparib, assessed by the investigator per RECIST criteria version 1.1. Secondary objectives include efficacy in terms of disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and duration of response (DOR); safety and an exploratory study of biomarkers associated with treatment efficacy and disease prognosis.
Unresectable metastatic colorectal cancer (mCRC) remains an incurable disease. After failure of conventional treatments involving fluoropyrimidines, oxaliplatin and irinotecan in combination or not with biotherapies targeting EGFR and VEGF; regorafenib shows a modest improvement in overall survival. Recently, trifluridine/tipiracil has also shown efficacy in phase 3 with an overall survival of around 7 months. Trifluridine/tipiracil has become the standard of care for advanced mCRC in most western countries. However, the objective response rate remains very low and the survival gain remains moderate (+2 months). Therefore, new strategies are needed to ensure that mCRC patients who have received multiple lines of therapy can receive more effective treatments. Based on previous clinical trials on IL-1 inhibition and our preclinical data, IL-1 inhibition may increase the efficacy of trifluridine/tipiracil. The goal is to test whether the addition of XB2001 to trifluridine/tipiracil could be synergistic.
Early detecting and removing of colorectal advanced adenomas can reduce incidence of colorectal cancer. In order to reduce the incidence of colorectal cancer, improve the early diagnosis of colorectal cancer, the investigators conducted this study to explore diagnostic accuracy of fecal immunochemical test in colorectal cancer screening population.
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.
This study will focus on postoperative patients of stage IIIB or stage IIIC colorectal cancer. These patients will start to accept chemotherapy in 3-4 weeks after operation, these patients were randomly divided into two groups, one group will accept adjuvant chemotherapy of mFOLFOX6 or CapeOX; another group will use mFOLFOXIRI, they can change the regimen to mFOLFOX6 or CapeOx after accepting not less than two complete chemotherapy regimen, if can not tolerate the adverse reaction of mFOLFOXIRI. The efficacy and safety of adjuvant chemotherapy will be compared between the two groups. Disease-free survival, overall survival, incidence of adverse reaction of chemotherapy and postoperative quality of life will be recorded.
