Active clinical trials for "Colorectal Neoplasms"

STRATEGIC-1 is a study designed to determine the best sequence of therapy in patients with metastatic colorectal cancer.

MetIri seeks to identify if metformin combined to irinotecan can improve tumor control.

This is a phase I/II multi-center open-label proof of concept study, consisting of two parts. Part A of this study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of dacomitinib plus PD-0325901 in patients with advanced KRAS mutant (KRASm) non-small cell lung cancer (NSCLC). Part B is designed to perform a randomized comparison of the combination of dacomitinib and PD-0325901 versus standard of care therapy in patients with advanced KRASm NSCLC. It is hypothesized that with this combination strategy the progression free survival of patients with KRASm NSCLC will be doubled.

Colorectal cancer is one of the most common malignant tumors, with the morbidity of approximate 100 million cases per year. About 40% of patients present with metastatic (stage IV) colorectal cancer at the time of diagnosis, and about 25% of patients with local lesion will ultimately develop metastatic disease. 5-Fluorouracil（5-FU) was the only efficacious treatment for metastatic colorectal cancer before the nineties of the 20th century, and afterwards as the discovery of chemotherapy such as oxaliplatin, irinotecan and capecitabine, response rate as well as survival had been improved greatly. Most of advanced colorectal cancer will progress after first-line treatment; therefore, seeking an efficient and low toxic maintaining regimen to prolong PFS becomes a hot topic in oncologic field. Some clinical researches demonstrated that maintaining treatment followed first-line treating advanced NSCLC could extend PFS and OS. In metastatic colorectal cancer, patients receiving 5-FU/leucovorin(LV) maintaining therapy experienced significantly longer PFS than that stopped chemotherapy after six cycles of FOLFOX4 in OPTIMOX2 study. One phase II study shown that median PFS was 13.9 months, and median OS was 31 months in 30 patients receiving first-line treatment of six- month FOLFOX4 followed by UFT as maintaining treatment . A non-randomized small sample study conducted in department of medical oncology of Sun Yat-Sen University Cancer Center indicated that patients receiving first-line treatment of XELOX followed by capecitabine as maintaining therapy has significantly prolonged median TTP, comparing with the non-maintaining treatment patients,(14months vs. 9 month, respectively). Above all, so far, there is no data to demonstrate that regular 4-6 month chemotherapy followed by maintaining treatment could prolong TTP and OS for advanced colorectal cancer. Capecitabine is effective for colorectal cancer, and was approved as palliative treatment for advanced colorectal cancer and adjuvant chemotherapy; in addition, with its relative less frequency of side effects and convenient oral administration, capecitabine as maintaining regimen could be prone to be accepted by patients. Therefore, our study is designed to investigate that capecitabine as maintaining treatment after first-line palliative chemotherapy could improve TTP and OS for patients with advanced colorectal cancer through a perspective randomized clinical study.

The purpose of this study is to evaluate the efficacy and safety of recombinant anti-tumor and anti-virus protein for injection plus capecitabine in treating patients with metastatic colorectal cancer who have progressed after standard therapy.

The purpose of this this trial is to prove the efficacy and safety of MGN1703 as a maintenance therapy after first-line chemotherapeutic treatment of metastatic colorectal cancer.

Approximately half of colorectal cancer (CRC) patients were first diagnosed after 70 years old. However, compared with younger patients, elderly patients were often undertreated in chemotherapy due to their impaired tolerance. Recently, there have been great controversy on adjuvant chemotherapy strategy for stage II/III CRC patients. As an oral fluoropyrimidine, capecitabine has been demonstrated to be equivalent to i.v. 5-Fu/leucovorin regimen in stage III CRC patients. In light of fewer adverse effects and better flexibility, capecitabine was regarded as an ideal alternative for elderly CRC patients, but the optimal dosage for stage II/III elderly CRC patients still remains inconclusive. Our trial expected to prospectively randomized 710 postoperative stage II/III elderly CRC patients (between 70 and 90 years of age) to adjuvant mono-chemotherapy with a standard dose of capecitabine (2500 mg/m2/day) or a reduced dose (2000 mg/m2/day). This is a non-inferiority phase 3 trial with a primary endpoint of 3-year disease free survival (DFS), and other outcomes include 3-year overall survival(OS), completion rate, toxic and adverse effects and quality of life(Qol). By this trial, we aimed to achieve more precise evidence on the individualized adjuvant chemotherapy strategy for stage II/III elderly CRC patients.

As an approach to improve efficacy and provide clinical benefit to cancer patients undergoing chemotherapeutic treatment regimens, Alchemia Oncology has developed a novel means for delivering anti-cancer agents to tumours. The drug delivery platform is based on the use of hyaluronic acid (HA), a novel excipient, in which, formulation with HA results in optimisation of cytotoxic drug uptake and retention within solid tumours. In the specific example of HA-Irinotecan, this new formulation of irinotecan has demonstrated enhanced efficacy in both nonclinical and early clinical studies. The current study is an investigation into the use of HA-Irinotecan in a Phase II single arm trial of FOLF(HA)iri plus cetuximab in irinotecan-naïve second line patients with KRAS wild type metastatic colorectal cancer. The study objectives are to confirm the safety and efficacy of FOLF(HA)iri plus cetuximab as second-line therapy in irinotecan-naïve metastatic colorectal cancer patients. It is expected that the study recruit approximately 40-50 patients in 1 year with subsequent treatment and follow up; thus the trial will run for approximately 2-3 years.

The primary objective of the two phase PERMAD trial is the evaluation of the impact of a personalized marker-driven treatment approach with early detection of progression and modification of treatment on cytokines and angiogenic factors (CAF) and efficacy. In regard of the two parts, the primary objective of the run-in phase (n=50 patients) with conventional switch of chemotherapy together with the anti-angiogenic agent is the determination of a distinct cytokines and angiogenic factor (CAF) profile during treatment with FOLFOX and bevacizumab, which allows early detection/prediction of progressive disease. The primary objective of the marker-driven randomized part (n=150 patients) with marker-driven switch of antiangiogenic agent and maintenance of chemotherapy is the evaluation of the efficacy of an early marker-driven switch of anti-angiogenic treatment (bevacizumab to aflibercept) This is a multicentre, multinational, open labeled, prospective, randomized, controlled phase II study designed to assess the clinical utility of an early marker driven change of anti-angiogenic treatment (bevacizumab to aflibercept) maintaining the chemotherapy backbone until definite radiological progression in first line treatment of patients with metastatic colorectal cancer. After completing the run in phase of the study, with at least 30 patients completing their first line treatment (due to progression, secondary resection or toxicity) and being evaluable for CAF analyses, the results will be reviewed by an Independent Data Monitoring Committee (IDMC). Based on that review the decision to continue with, modify or cancel the randomized part will be made. The primary endpoint of the run-in phase with conventional switch of chemotherapy together with the anti-angiogenic agent is: • Progression free survival (PFS1) of first line treatment The primary endpoint of the randomized part with marker-driven switch of antiangiogenic agent and maintenance of chemotherapy is: • Progression free survival rate at 6 months (PFSR@6) after first cycle after randomization.

The purpose of this study is to evaluate the efficacy of dendritic and cytokine-induced killer cells (DC-CIK) for colorectal cancer (CRC).
