Active clinical trials for "Colorectal Neoplasms"

A single-central,open-label,safety,pharmacokinetics,phase I study. Biological:Recombinant Anti-EGFr Antibody Two dose levels: Low-dose level patients received initial dose 100 mg/m2 and 4 weeks later 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.High-dose level patients received cetuximab initial dose 400 mg/m2 and 4 weeks later loading 400 mg/m2 and 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.

Irinotecan and raltitrexed are active against advanced colorectal cancer (ACC), act through different mechanisms, and have only partially overlapping toxicity profiles. The purpose of this study is to evaluate efficacy and safety of irinotecan plus raltitrexed as second-line treatment in advanced colorectal cancer patients.

This study evaluates the safety, tolerability, preliminary efficacy and pharmacokinetics of Simmitecan in patients with advanced solid tumors and Simmitecan, 5-fluorouracil and Leucovorin Calcium,thalidomide in patients with advanced solid tumor or advanced/metastatic colorectal cancer.

This study is try to evaluate the effect of cetuximab monotherapy as maintenance treatment, versus continuation after 8 courses of induction therapy with cetuximab plus standard chemotherapy regimen (FOLFIRI or mFOLFOX6）in metastatic colorectal cancer (mCRC) patients. The maintenance treatments are continued until disease progression or untolerated toxicity. The aim of this study is to demonstrate that cetuximab monotherapy is non-inferior to continuation treatment, in those mCRC patients who responded to induction therapy(SD, PR, or CR), and carry biomarker-panels (KRAS, NRAS, BRAF, and PIK3CA) favor EGFR antibody.

The primary objective of this study is to evaluate the safety of autologous dendritic killer cell (DKC) in patients with metastatic solid tumor and to evaluate the maximum tolerated dose (MTD) of DKC. The primary endpoint of safety evaluation includes physical examination, assessment of vital sign, laboratory test, concomitant medication, and adverse event (AE). The secondary endpoints regarding efficacy includes the generation of tumor specific immune response by detecting CD3+ CD8+ CD69+ IFN-gamma+ T cells, and the improvement of quality of life

The purpose of this open-label, dose-escalation phase I trial is to evaluate the safety, tolerability and pharmacokinetic profiles and to assess the efficacy of CKD-516 Tablet in Combination with Irinotecan inj. in Patients with Previously Treated Advanced Colorectal Cancer

The optimum regimen of maintenance treatment after first-line chemotherapy in patients with metastatic colorectal cancer (mCRC) is unknown. This study was designed to determine the efficacy and safety of maintenance treatment with capecitabine metronomic chemotherapy versus conventional chemotherapy.

Colorectal cancer is an aggressive malignancy with a poor overall outcome. The purpose of this study is to evaluate the feasibility, safety and efficacy of neoadjuvant oxaliplatin, irinotecan combined with 5-fluorouraci/leucovorin or S-1 or capecitabine in patients with resectable colorectal cancer.

There is a paucity of data on the histopathological response of peritoneal tumor deposits from colorectal cancer to neoadjuvant chemotherapy. Particularly, no prospective assessment of chemotherapy-associated histopathological response within the peritoneum has been performed so far. Therefore, there is an urgent need to conduct a clinical trial aimed at prospectively assessing the histopathological response within the peritoneum in patients with peritoneal metastasis from colorectal cancer. Recently, Loupakis et al. reported that the triplet regimen of 5-fluorouracil, oxaliplatin and irinotecan (FOLFOXIRI) in combination with bevacizumab significantly improved median progression-free survival in metastatic colorectal cancer patients from 9.7 to 12.1 months as compared with fluorouracil, leucovorin, and irinotecan (FOLFIRI) + bevacizumab. In view of these data, it is likely that FOLFOXIRI + bevacizumab will also lead to a significant improvement of the histopathological response within the peritoneum of patients with peritoneal metastasis from colorectal cancer (pcCRC) as compared with previous standard chemotherapy. The investigators hypothesize that FOLFOXIRI + bevacizumab will induce a pCR or major response in peritoneal tumor deposits in >30% of patients (taking the response rate to FOLFOX- or FOLFIRI-based neoadjuvant chemotherapy from the published literature as a reference).

BACKGROUND: For patients with liver-limited metastatic colorectal cancer (mCRC), complete resection of liver metastases is the only potentially curative treatment. The current goal of medical treatment for colorectal cancer with initially unresectable liver metastases is to maximize the rate of secondary resection and prolong overall survival (OS). A strong correlation was found between response rate and secondary resection rate of metastases, and the triple drugs combination of infusional 5-fluorouracil/leucovorin (5-FU/LV), irinotecan, and oxaliplatin (FOLFOXIRI) was recommended can be used in selected patients with potentially resectable metastases in order to improve response rate and make resection more possible. The addition of a anti-VEGFs monoclonal antibody such as bevacizumab to chemotherapy has been shown to increase response rate, resection rate and improve OS in the first-line treatment of mCRC patients. The efficacy and safety of bevacizumab in addition to triplet drugs were previously tested in OLIVIA trial, the resection rate of liver metastases of 49% was reported, and the response rate was 81%; most common grade 3-4 adverse events was neutropenia. On the basis of such promising results, we conducted the present randomized study to explore whether FOLFOXIRI plus bevacizumab compared with FOLFOXIRI alone as first-line treatment could improve radical resectability in patients with RAS mutation-type, unresectable liver-only metastatic colorectal cancer. OBJECTIVE: The primary objective of the FOBULM study is to evaluate the efficacy of FOLFOXIRI plus bevacizumab compared to FOLFOXIRI alone in patients with initially unresectable liver-limited RAS mutation-type mCRC. Secondary objectives are safety and tolerability of the treatment, efficacy in terms of objective response rate (ORR), OS, progression free survival (PFS), quality of life and an assessment of biomarkers for predictive response and prognosis.
