Active clinical trials for "Colorectal Neoplasms"

This is a Phase II multi-center 2-sequential cohorts trial, designed to assess the objective response rate of two anti HER2 combination in advanced disease CRC patients harbouring an amplified HER2 tumor assessed according to HERACLES Diagnostic Criteria by FISH/SISH. Cohort A: monoclonal antibody trastuzumab, used in combination with the small molecule tyrosine kinase inhibitor lapatinib. Cohort B, monoclonal antibody pertuzumab, used in combination with the antibody drug conjugate trastuzumab-emtansine. Please note that cohort A accrual has been closed and endpoint already reached.

This project intends to make a study of personalized medicine evaluation system establishment for liver cancer, gastric cancer and nasopharynx cancer to provide strong support for the development of Precision Medicine and personalized medicine for the patients of high-incidence-rates cancer in China.

To evaluate the efficacy and safety of neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) in the patients with resectable liver metastasis of colorectal cancer

Familial adenomatous polyposis (FAP) leads to adenomas and eventual adenocarcinomas in colon and less frequently, duodenum. Chemopreventive strategies have been studied in FAP patients to delay the development of adenomas and cancers. The non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase-2 inhibitor have shown the regression of colorectal and duodenal adenomas in FAP patients. However, these drugs showed gastrointestinal damage and cardiovascular risks, and new preventive strategies are needed. Niclosamide, an anti-helminthic drug, has recently been suggested to have a suppressive effect on tumorigenesis via inhibition of Wnt pathway, and have no significant safety issues. The investigators devised a double-blind randomized controlled trial to evaluate the effect of niclosamide on polyps of colorectum and duodenum in FAP patients.

This study proposed by increasing dosage and expand the "3 + 3" queue, main component is divided into two phases, phase 1 for dose escalation, according to preliminary data recommended doses starting dose of climbing, the purpose is to evaluate the safety of combination therapy, tolerance, and explore the maximum tolerated dose (MTD) and right dose recommended development stage;Phase 2 was the expansion phase. Patients were included in the expansion study according to the appropriate dose recommended in phase 1, to further evaluate the safety and tolerability of combination therapy, recommend appropriate dose for phase II clinical trial, and preliminarily explore the efficacy of combination therapy.

The objective is to investigate the efficacy and safety of two-weekly alternative regimen of Bevacizumab plus XELOX/XELIRI for First-line Treatment in Unresectable Advanced Colorectal Cancer.

In 2018, colorectal cancer is the third most common malignant tumor in terms of morbidity and second mortality in the world. Surgical resection is still the main treatment for colorectal cancer.With the introduction of the ERAS, the latest international and domestic guidelines for fasting before surgery all advocate shortening the fasting time. For example, 2 hours before surgery, oral take cleared fluids, including water, sugar water, fruit juice, tea and black coffee (without milk) is allowed.Solid food can be consumed 4 hours before surgery, and oral diet should be resumed as soon as possible after surgery. Changes in diet, nutritional status, and physical activity are closely related to the incidence of colorectal cancer. Therefore, we believe that the intestine may be very sensitive to different fasting times during the perioperative period. Prolonging the fasting time may improve the prognosis by improving postoperative insulin resistance, reducing inflammation and protecting anti-tumor immune function in patients with colorectal cancer.Prolonged fasting time seems to be contrary to the results of some studies, and whether it is applicable to patients with tumor surgery is unclear. Therefore, there is an urgent need to conduct large-scale, prospective, randomized controlled clinical studies to clarify the most suitable perioperative fasting strategy (including composition, interval, and amount) for cancer patients, which can not only reduce surgical stress and speed up postoperative rehabilitation,reduce postoperative metastasis and recurrence and improve mid- and long-term prognosis.

The phase I/II study was designed to evaluate if the regimen of Irinotecan, Oxaliplatin, Capecitabine (XELOXIRI) and Bevacizumab is a superior first-line option for patients with metastatic colorectal cancer(mCRC) in terms of safety and efficacy.

This is a prospective randomized study to evaluate the difference in the rate of surgical site infection between the patients who used Sodium Picosulfate solution(PicosolutionⓇ) and tablet Oral Sulphate Solution(ORA·FANGⓇ) for bowel preparation before colorectal cancer surgery .

The primary endpoint is to evaluate the progression-free survival (PFS).
