Active clinical trials for "Colorectal Neoplasms"

In this study, participants with stage IV Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) colorectal carcinoma (CRC) will be randomly assigned to receive either pembrolizumab or the Investigator's choice of 1 of 6 standard of care (SOC) chemotherapy regimens for the treatment of advanced colorectal carcinoma. The primary study hypothesis is that pembrolizumab will prolong progression-free survival (PFS) or overall survival (OS) compared to current SOC chemotherapy.

This study will evaluate the efficacy, safety, and pharmacoeconomics of oral capecitabine in patients with metastatic colorectal cancer. The anticipated time on study treatment is 3-12 months, and the target sample size is 28 individuals.

This study will evaluate the safety and tolerability of capecitabine (Xeloda) in participants who have undergone surgery for colon cancer. Oral Xeloda will be administered twice daily in 3-week cycles for a total of up to 8 cycles. The anticipated time on study treatment is 24 weeks, and the target sample size is 70 individuals.

National multicentric phase II trial evaluating whether single agent cetuximab is effective as maintenance therapy after 8 cycles of first line FOLFIRI plus cetuximab in mCRC patients with KRAS and NRAS wild-type genes, assessed by progression-free survival at 6 months after start of maintenance therapy.

Background Hepatic metastases of colorectal cancer (MCC) is quite common and is a major source of morbidity and mortality. There has been evidence to show that hepatic arterial chemoembolisation using DC beads (drug eluting beads, 100-300μm) loaded with irinotecan (DEBIRI) showed improved overall survival when compared to systemic therapy (FOLFIRI), but being larger they have their limitations. New 70-150μm beads are recently available and currently there is limited data concerning its use. Safety of these beads have not been tested in local patients. Hypothesis / Aim To study the safety and pharmacokinetics of the smaller 70-150μm DEBIRI in a pilot study of 5 patients. The smaller 70-150μm beads will be able to deliver a more consistent and higher dose to tumoral tissue with a smaller systemic dose. Being smaller and less embolic, it will also be better tolerated. Patients will also be genotyped for their UGT1A1*28 and UGT1A1*6 polymorphism status as the latter genotypes are associated with decreased clearance of irinotecan and SN-38 in Asian patients. Methods Single centre, pilot study, prospectively recruiting 5 patients with unilobar disease, refractory to systemic chemotherapy The primary endpoints: establish safety and toxicity profile of the irinotecan loaded DEBIRI beads establish pharmacokinetics and systemic exposure of irinotecan and its active metabolite, SN-38. The secondary outcome measurements: the incidence and severity of adverse events, liver function parameters and laboratory abnormalities; response rate, progression free survival overall survival Clinical Significance This treatment modality has the advantage of directly delivering irinotecan to the liver metastases from colorectal cancer. This local mode of drug delivery may result in a higher intratumoral drug concentration and rapid tumour shrinkage leading to downstaging of the hepatic metastatic lesions. These therapeutic outcomes may also downstage patients to hepatic resection.

This randomized phase II trial studies how well irinotecan and cetuximab with or without bevacizumab work in treating patients with RAS wild-type colorectal cancer that has spread to other places in the body (locally advanced/metastatic) and cannot be removed by surgery. Irinotecan may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as cetuximab and bevacizumab, may help the body?s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving irinotecan and cetuximab with or without bevacizumab may work betting in treating patients with colorectal cancer.

This randomized phase II trial studies how well lower-dose compared to standard dose regorafenib works in treating patients with colorectal cancer that has spread from the primary site (place where it started) to other places in the body and does not respond to treatment. Regorafenib may stop the growth of colorectal cancer by blocking the growth of new blood vessels necessary for tumor growth and by blocking some of the enzymes needed for cell growth. It is not yet known whether lower-dose or standard dose regorafenib is more effective in treating patients with colorectal cancer. Clobetasol propionate is a steroid cream that is commonly used to treat a variety of skin conditions and may help prevent hand-foot skin reactions in patients receiving regorafenib.

Open-label, randomized, multicenter, Phase II trial designed to estimate the efficacy of CAPTEM versus FOLFIRI as second line treatment in MGMT methylated, RAS mutated advanced CRC patients who have progressed on or after first-line oxaliplatin containing chemotherapy for metastatic disease. MGMT will be assessed centrally at Pathology Department of Fondazione IRCCS Istituto Nazionale dei Tumori prior to enrollment. A minimum of ten 3-micron unstained sections on charged slides of tumor will be required and methylation status will be provided within a maximum of seven days to the Study Centers. Presence of RAS mutation will be assessed at each local participating center. Eligible patients will be randomized in a 1:1 ratio to one of two treatment arms: Arm A (experimental arm): CAPTEM Arm B (control arm): FOLFIRI Study treatment will be given in cycles repeated every 28 days for Arm A and every 14 days for Arm B. Patients in Arm A will receive capecitabine at the oral dose of 1500 mg/mq/die bid from day 1 to day 14 every 28 days plus temozolomide 150 mg/mq/die bid starting on day 9 to 14 every 28 days. Patients in Arm B will receive FOLFIRI chemotherapy starting Day 1 q2w (every cycle) starting on Day 1 of Cycle 1. FOLFIRI consists of irinotecan (starting dose of 180 mg/m2) on day one only; 5-FU 7 (starting bolus and 22-hour infusional doses of 400 mg/m2 and 600 mg/m2, respectively), and leucovorin (racemic, starting dose of 200 mg/m2 or L-form, starting dose of 100 mg/m2) for two consecutive days. Treatment will continue for up to 6 cycles in Arm A and up to 12 cycles in Arm B or up to disease progression, unacceptable toxicity or informed consent withdrawal. Randomization will be stratified across the treatment arms by the following predefined stratification variables: disease progression within 9 months from the start of first-line oxaliplatin-containing chemotherapy (< vs. ≥9 months); prior bevacizumab in combination with oxaliplatin-based chemotherapy (yes vs. no). Efficacy assessments will be performed every 2 cycles in Arm A and every 4 cycles in Arm B until progression. The study is expected to enrol approximately 82 patients who meet the eligibility criteria.

To determine the efficacy (as measured by progression-free survival [PFS] rate at 8 weeks) of regorafenib in subjects with metastatic colorectal cancer (CRC) whose disease is refractory to standard therapies and who were never exposed to antiangiogenic therapy.

The purpose of the study is to measure high grade (3-5) toxicity of regorafenib and to monitor the impact of treatment with regorafenib on the quality of life in older adults with metastatic colorectal cancer.
