Active clinical trials for "Colorectal Neoplasms"

The purpose of this study is to assess the safety and tolerability of different dose-escalation approaches of regorafenib in mCRC patients.

Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3, whose anti-tumor and anti-angiogenesis effects have been validated in preclinical tests. In PhaseⅡb study, a significantly improved Progression Free Survival (PFS) was found in patients with advanced colorectal cancer treated with Famitinib compared to placebo. On the other hand, the toxicity of Famitinib was manageable in both PhaseⅠand Ⅱb studies. The purpose of this study is to determine whether Famitinib can improve Overall Survival (OS) compared with placebo in total 540 patients with advanced colorectal cancer who have failed in previously received at least two lines of standard chemotherapy.

Fruquintinib administered at 5mg once daily(QD) in 4 weeks treatment cycle (three weeks on and one week off) was well tolerated and demonstrated encouraging preliminary clinical antitumor activity in patients with metastatic colorectal cancer (CRC) in phase Ib and phase 2 study. This study is aimed to evaluate the efficacy and safety of Fruquintinib in the treatment of patients with metastatic CRC who have progressed after second line or above standard chemotherapy

This is a single center, open label dose frequency escalation study of CryoVax®. personalized anti-tumor vaccine protocol combining the cryoablation of a selected metastatic lesion with intra-lesional immunotherapy with AlloStim®. The in-situ (in the body) cancer vaccine step combines killing a single metastatic tumor lesion by use of cryoablation in order to cause the release of tumor-specific markers to the immune system and then injecting bioengineered allogeneic immune cells (AlloStim®) into the lesion as an adjuvant in order to modulate the immune response and educate the immune system to kill other tumor cells where ever they reside in the body.

Metastatic diseases were found in 20-25% of patients with initial diagnosis of colorectal cancer and developed in up to 50% of patients. Owing to limited post-treatment response of 5-fluorouracil (5-FU) combined with leucovorin (LV) obtained in mCRC (metastatic colorectal cancer) patients, other therapeutic agents with different mechanisms were considered, such as irinotecan, a potent inhibitor of topoisomerase I, which is involved in the unwinding of DNA during replication. Bevacizumab is a humanized monoclonal antibody that inhibits tumor angiogenesis by blocking vascular endothelial growth factor (VEGF) and was the first antiangiogenic agent approved for the treatment of cancer. Infusional fluorouracil/leucovorin plus irinotecan-based regimen (FOLFIRI) with bevacizumab has been widely used as first-line treatment for patients with metastatic colorectal cancer (mCRC). Recently, the investigators have shown that prospective analysis of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) genotyping for irinotecan dose escalation (FOLFIRI regimen) with combination of bevacizumab biweekly as the first-line setting in mCRC patients (ASCO Abstract #491 - 2013 Gastrointestinal Cancers Symposium). In this study, the investigators will enroll approximately 320 mCRC patients (It was considered that an increase of response rate of 15% compared to conventional irinotecan dose of 180 mg/m2, and these were chosen as parameters with which to calculate the study power. Initial power calculation was suggested that a minimum of 140 patients in each group would be required to achieve statistical significance with a power of 80% at the 5% significance level. It is estimated that about 10% of 320 mCRC patients fail to complete the study). For these enrolled patients, the investigators will randomize and divide these patients into two groups: control group and study group. Control group includes mCRC patients who will receive the conventional regimen of FOLFIRI plus bevacizumab. Otherwise, patients in the study group will have genotyping of UGT1A1 before therapy, and dose escalating of irinotecan will depend on results of genotyping.

The primary goal of this Phase 1 study is to characterize the safety and tolerability of MGD007 and establish the maximum tolerated dose (MTD) and schedule of MGD007 administered to patients with metastatic colorectal carcinoma. Pharmacokinetics, pharmacodynamics, and the anti-tumor activity of MGD007 will also be assessed.

(TSB) is a botanical drug and applied patent in the United States (US patent No. 7,138,428 B2), Japan (Patent No. 5441947) and Taiwan (Patent No. I432191 and I282280). The R&D laboratory in TSB is ISO/IEC 17025 certified by Taiwan Accreditation Foundation (TAF) and the laboratory number is 2026.The trade name of TSB-9-W1 is "IDS" in English, the registration number is 01472800 at 2011 by Intellectual Property Office (IPO), Taiwan. A phase I and pk study to determine the Maximum Tolerated Dose (MTD) and to evaluate the safety and efficacy profiles of TSB-9-W1 in pre-treated patients with metastatic colorectal cancer (mCRC). there are 5 cohorts and a minimal 2 patients and up to 30 patients are required at phase I. This is a single arm study. All eligible patients with mCRC will receive TSB-9-W1 treatment. Each treatment cycle is composed by a contiguous 2-day oral administration and a contiguous 3-day rest. Patient should take the study drug once daily before meal with approximately 250 ml or appropriate amount of water.

The main objective of this study is to test the safety and effectiveness of DS-8201a for participants with HER2-expressing advanced colorectal cancer.
