Filter by:The purpose of the Phase 1/2a study is to evaluate the safety and tolerability of SNK01 in combination with trastuzumab or cetuximab in order to determine the maximum tolerated dose (MTD)/recommended Phase 2 dose (RP2D), and the preliminary efficacy for each combination regimen.
This study is to assess the impact of the CARES-REACH intervention on colorectal cancer screening rates.
Rationale: Throughout the years, there has been a rapid change in the perioperative protocols and procedures surrounding colorectal surgery. Upon the introduction of the Enhanced Recovery After Surgery (ERAS) program in Western countries, an improvement in postoperative outcomes was seen. Nowadays, researchers focus on further improving the current standard ERAS programs enabling an accelerated version hereof. Objective: The aim of this study is to investigate the feasibility and safety of a 23-hour accelerated ERAS protocol (ERAS 2.0) for patients undergoing colorectal surgery compared to a retrospective cohort of patients who followed ERAS 1.0 for colorectal surgery. In this ERAS 2.0 protocol, patients undergoing colorectal surgery will be discharged within 23 hours after surgery. Study design: This study is an investigator-initiated, single-center prospective study. Study population: Patients aged ≥ 18 years ≤ 80 undergoing surgical resection for colorectal pathology that meet the eligibility criteria will be invited to participate in this study. Intervention: Adhering to a strict multidisciplinary and multifaceted ERAS 2.0 protocol, patients receiving elective colorectal surgery will be discharged 23-hours after surgery. Main study parameters/endpoints: Rate of the successful and safe application of the 23-hour accelerated ERAS 2.0 protocol for patients undergoing elective colorectal surgery. Success rate will be measured in readmission rate and safety will be measured with rate of serious adverse events (Clavien Dindo ≥3b). Success rate (feasibility) will also be measured in percentage of patients who were not able to be discharged 23 hours after surgery.
Real world study was used to evaluate the therapeutic effect of Fuzheng anti-tumor therapy on colorectal cancer patients in stage II and III after surgery and standard chemotherapy, and the prediction model of dominant population of Fuzheng anti-tumor therapy was constructed by using real-world data and gene expression profile data.
Given a context where patients autonomy respect is important, it is necessary to pay a sustained attention to the patients care and life experiences, as well as the families and relatives of patients with colorectal cancer or patients in remission of colorectal cancer. Thanks to families and relatives data, it will allow to improve the analyses carried out by the "Societal Cancer Observatory" in 2016.
This trial is a randomized, double-blind, multinational Phase III study to evaluate the efficacy and safety of preemptive treatment with FTD/TPI compared with administration of placebo as follow-up, which is the standard of care, in patients who underwent curative resection of colorectal cancer and then tested positive for ctDNA.
This study will test whether the combination of cisplatin, nivolumab, and temozolomide is an effective treatment for in people with advanced and/or metastatic colorectal cancer that is mismatch repair-proficient (MMR-proficient). The researchers will also look at how safe the study drug combination is in participants.
This is an efficacy and safety study of olaparib alone or in combination with bevacizumab being compared to bevacizumab with a fluoropyrimidine in participants with unresectable or metastatic colorectal cancer who have not progressed following first-line induction. The primary hypotheses are: Olaparib + Bevacizumab is superior to a fluoropyrimidine + Bevacizumab with respect to progression-free survival (PFS) using Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR); Olaparib is superior to a fluoropyrimidine + Bevacizumab with respect to PFS using RECIST 1.1 as assessed by BICR. As of amendment 5 study enrollment is being discontinued and study participants randomized to one of the two experimental arms (olaparib plus bevacizumab or olaparib monotherapy) must discontinue study intervention. Participants who are still on study treatment will no longer have tumor response assessments by BICR.
Colorectal cancer (CRC) is a leading cause for cancer related mortality in the western world with a lifetime risk of 6%. Etiology is complex, while genetic background significantly affects the risk. Around one third of all genetic disorders as well as most cases of Familial Adenomatous Polyposis (FAP) and a large proportion of all sporadic CRC cases occur as a result of premature nonsense mutations (creating a stop codon) in an individual's adenomatous polyposis coli (APC) gene. Nonsense mutations are single-point alterations in the DNA that prematurely halt the protein translation process, producing a shortened, nonfunctional protein. In many of these cases, if the cell can be 'persuaded' to ignore the premature stop codon signal, the resulting protein may be able to ameliorate or stop the disease. Recently, members of the aminoglycoside family of antibiotics have been found to induce ribosomal read-through of nonsense mutations, leading to expression of a full length, functional protein. Investigators have recently shown that members of the aminoglycoside and macrolide antibiotic families can induce read-through of the nonsense mutations in the APC gene and lead to reduced oncogenic phenotypes in CRC cells and in different mice models. The aim of this project is to determine the ability of the macrolide antibiotic-Azithromycin to induce read-through of the nonsense mutations in the APC gene and to induce expression of a full length, functional APC protein in patients suffering from FAP and to tests its effect on adenoma number and size and on desmoid tumors in these patients. The future goal is to maximize the effect of stop-codon suppressors on APC while minimizing side effects. In this study the investigators will select FAP patients which carry APC nonsense mutations, treat them with Azithromycin PO for 4-6 months and examine colonic and duodenal adenomas as well as abdominal desmoid tumors, that will be documented before during and after treatment. In parallel, investigators will test polyp, adenoma and desmoid tissue samples as well as blood samples from these patients for changes in expression levels of the APC protein and related oncogenic markers. Suppression of nonsense mutations within the APC gene should be of benefit for patients suffering from FAP, attenuated FAP or multiple adenomas and for patients with advanced or diffuse CRC. Furthermore, given the rapid progress being made in the identification of different nonsense mutations in human genes that lead to mostly non-curable disease, the identification of clinically approved compounds that suppress nonsense mutations and that can be administered long-term without significant side effects would open new venues in the treatment of genetic human diseases that arise from pre-mature stop codons in important coding sequences. Immediate goal: establish the ability of Azithromycin to read-through APC nonsense mutation in FAP patients. The read-through effect of Azithromycin will be clinically tested by counting and measuring the number and size of both colonic and duodenal adenomas before and over treatment and by measuring the size of known desmoid tumors. Samples of the adenomas and desmoid tumors will be tested by western blot, immunofluorescence and immunohistochemistry for restoration of APC expression and changes in oncogenic markers. These experiments should be conducted within 6 month. Long term objective: 1. Determine the lowest dose of Azithromycin that can inhibit growth of colonic neoplasia and CRC in patients expressing a truncated APC protein due to nonsense mutations. 2. Examine the ability of a panel of additional macrolide antibiotics to induce APC nonsense mutation suppression using in-vitro methods. Investigators will focus on macrolide antibiotics that are currently in clinical use and are administrated for long terms. These objectives should take around 4 month and will be conducted in parallel.
Colorectal cancer is a leading cause of cancer-related morbidity and mortality. CRC-related death can be prevented through fecal occult blood test screening. Because of economic and high sensitivity, fecal immunochemical test is recommended for screening population of CRC. The purpose of this study is to compare the accuracy of 4 different fecal occult blood testing in medium and high risk screening population in Chinese.
