Active clinical trials for "Colorectal Neoplasms"

Based on the results from preclinical study, the investigators suggest that the addition of simvastatin at a dose of cardiovascular use (40 ~ 80 mg qd daily) may overcome cetuximab resistance in KRAS mutant colorectal cancer via B-Raf protein degradation and inducing Bim and Bad. Given the result of a phase II FOLFIRI plus cardiovascular dose of simvastatin (80mg qd daily) and this study, phase II study of conventional cetuximab treatment with 40 mg simvastatin is planned in metastatic colorectal cancer patients with KRAS mutation.

The purpose of this study is to evaluate if giving bevacizumab prior to chemotherapy compared to giving bevacizumab at the same time as chemotherapy improves patient overall response to treatment.

116 eligible patients with confirmed non-metastatic colorectal adenocarcinoma and anemia will be randomized to receive either oral ferrous sulphate (control) or intravenous ferric carboxymaltose (intervention). It is hypothesized that intravenous iron supplementation is more efficacious than oral iron therapy.

This pilot study is being mounted to assess whether treatment assignment by ERCC-1 gene expression status suggests better clinical results from historical experience in metastatic colorectal cancer (mCRC). In wild type KRAS mCRC patients treated with either FOLFOX or FOLFIRI in combination with cetuximab the median response rate is approximately 60-65%. Biomarker directed treatment in this study may demonstrate that patients with low ERCC-1 treated with FOLFOX and cetuximab, and those with high ERCC-1 treated with FOLFIRI and cetuximab, will improve response rate to 70-75%. KRAS wild type patients will be treated with 6 cycles of one of the following regimens chosen for optimization based on patient characteristics (primary treatment phase). Patients with ERCC-1 < 1.7 relative gene expression of ERCC-1 over ß-actin (ERCC-1 low) will be assigned to treatment with mFOLFOX6 in combination with Cetuximab. Patients with ERCC-1 gene expression > 1.7 relative gene expression of ERCC-1 over over ß-actin (ERCC-1 high) will be assigned to treatment with FOLFIRI in combination with Cetuximab.

Primary Objective: To evaluate the improvement in progression-free survival (PFS) of aflibercept versus placebo in participants with metastatic colorectal cancer treated with FOLFIRI as second-line treatment for metastatic disease. Secondary Objectives: To compare the overall survival (OS) in the 2 treatment arms. To compare the overall response rate (ORR) in the 2 treatment arms. To assess the safety profile of the 2 treatment arms. To assess immunogenicity of intravenous (IV) aflibercept in selected centers.

Bevacizumab in combination with chemotherapy represents a standard of care for first-line treatment in patients with advanced colorectal cancer. Molecular predictive factors for bevacizumab efficacy have not yet been identified therefore selection of patients more likely to benefit from such a treatment approach is not possible. Retrospective analyses suggested that LDH serum levels may influence the clinical activity of anti-angiogenetic drugs. Primary aim of our clinical trial will be to prospectively ascertain whether bevacizumab in combination with chemotherapy has an improved clinical activity in patients with high LDH serum levels compared to patients with normal LDH serum levels

This is an open-label phase III study of regorafenib in patients with metastatic colorectal cancer (mCRC) who have progressed after all approved standard therapy. The purpose of this study is to provide additional information about the safety profile of Regorafenib.

The study is designed to analyze the pathological tumor response on resected colorectal cancer metastases after preoperative treatment with bevacizumab combined with FOLFOX or FOLFIRI regimen in a prospective cohort and to correlate this response with patient's outcome.

Study Design: Multicenter, non randomized, open label phase II study designed to evaluate the efficacy and safety of Gemcitabine/Pemetrexed combination. Enrollment period: 18 months. Treatment period: maximum for 24 weeks for each patient (12 cycles lasting 2 weeks). Total duration of the study: 24 months. Number of Subjects: Approximately 38 subjects will be enrolled on study: - First stage:12 patients enrolled If 1 or 0 responses were observed, the trial had to be terminated: - Second stage: an additional of 23 patients were to be enrolled. If 5 or less responses were observed in 35 patients, the combination would not be considered worthy of further study, while if 6 or more responses were observed, the combination would be considered sufficiently active to warrant further testing. Taking into account an invalidity rate of 5%, 38 patients will be needed for this step.

Prospective non randomized, non-comparative, dose escalation, two arms open phase I trial to assess the safety and tolerability of capecitabine given in combination with aflibercept in patients with measurable or evaluable, chemorefractory digestive tumors or breast tumors in terms of the Maximum Tolerated Dose (MTD) and the Dose-Limiting Toxicities (DLTs), To establish the Recommended Phase II Dose (RP2D) of capecitabine in combination with Aflibercept.
