Active clinical trials for "Colorectal Neoplasms"

This is a Phase I, dose finding, multicentre study evaluating the maximal tolerated dose of Glivec® in combination with mFOLFOX-Avastin®. Patients will be enrolled into each dose level in 3 patient cohorts. Additional cohorts will be enrolled, or dose levels opened, subject to the toxicities observed. Once the MTD has been determined the dose level below will be re-opened and extra patients, to a total of 15, will be enrolled.

To evaluate and compare the efficacy and safety of regorafenib versus placebo in subjects with colorectal cancer (CRC) after curative resection of liver metastasis and completion of all planned chemotherapy.

The primary objective of this study is to compare the additive efficacy of SIM versus placebo in combination with leucovorin (folinic acid), irinotecan, and fluorouracil (FOLFIRI) as measured by improvement in progression-free survival (PFS) in participants with metastatic KRAS mutant colorectal adenocarcinoma who have progressed following a first-line oxaliplatin- and fluoropyrimidine-containing regimen.

A study to evaluate the efficacy and tolerability of ABT-165 plus FOLFIRI compared to bevacizumab plus FOLFIRI in participants with previously treated metastatic adenocarcinoma of the colon or rectum.

This study will test the ability of an immune modulator, anti-OX40 (MEDI6469) to alter the immune cell environment within colorectal cancer metastases. The drug will be administered to patients before surgical treatment.

A safety and efficacy study of first line therapy with Vectibix® in combination with FOLFIRI or FOLFOX to validate a prognostic score in adult patients with RAS wild-type metastatic colorectal cancer in a real world setting (VALIDATE)

Different subtypes of serrated lesions have been recently described. Among them, both sessile serrated polyp/adenoma (SSP/A) and traditional serrated adenoma (TSA) could have malignant potential through the serrated pathway or CIMP. These lesions, as a potential source of interval cancer, should also be considered in colorectal cancer (CRC) population-based screening programs. It is believed that this new described pathway could be responsible for up to 30% of all CRC. Unlike the traditional adenoma, serrated lesions are difficult to diagnose because of their particular endoscopic appearance and their still unclear histological criteria. Furthermore, they have specific molecular changes and, through them, they could evolve into CRC faster than the adenoma. The real prevalence of the serrated lesions and their specific risk for developing new synchronous/metachronous lesions, or even malignancy, remains unknown. For all these reasons, we don't know if these patients could constitute a different CRC-risk group and if specific recommendations are needed during their follow-up. This is a prospective longitudinal study developed within the framework of the CRC-screening program in the Valencian Community (Spain). We expect to include a total of 700 individuals who will be followed during 10 years. In our study, we will collect epidemiologic variables related to the patient, variables related to all the polyps, and mutational (BRAF, KRAS, MSI), and CpG-island methylation status of serrated lesions. Strict endoscopic and histological criteria will be applied for the diagnosis of serrated lesions. All lesions detected at the index colonoscopy and during follow-up will be evaluated. The purpose of this study is to correlate epidemiologic data, histological characteristics and the molecular profile of the serrated lesions with findings during follow-up, in order to define stratified groups according to their risk of developing new lesions or CRC in the future.

This study is a multicenter ,randomization, open control study to evaluate the efficacy and safety of Raltitrexed-based chemotherapy and 5-fluorouracil-based chemotherapy in the peri-operative treatment of patients with Liver Metastasis From colorectal cancer (CRC).

This study, for patients who have Stage IIIC colorectal cancer and who underwent 5-fluorouracil/leucovorin with oxaliplatin (FOLFOX) chemotherapy after surgery, will test to see if regorafenib given after the completion of FOLFOX improves treatment, compared to standard of care (SOC), which is no further treatment.

This study describes the survival outcomes of advanced stage breast, colorectal, ovarian and pancreatic cancer patients receiving advanced integrative oncology (AIO) treatment at participating North American integrative oncology clinics. This study also aims to describe the integrative treatments recommended by naturopathic doctors (NDs) for these participants alongside their conventional care treatments. Sub-studies will evaluate health-related quality of life, cost of cancer care, and qualitative experience of care in a subset of Canadian participants.
