Active clinical trials for "Colorectal Neoplasms"

This study will evaluate whether NKTR-102, an investigational drug has an anti-tumor effect in patients with colorectal cancer. This study will also evaluate how the safety and anti-tumor activity of NKTR-102 compares with irinotecan, a cancer drug that is approved for use in the US for treatment of patients with certain types of colorectal cancer.

Background: The drug R935788 (fostamatanib disodium) is a kinase inhibitor (i.e., it interferes with cell communication and growth and may prevent tumor growth). R935788 has shown promising activity in NCI-60 (a panel of 60 diverse human cancer cell lines) against colon cancer, non-small cell lung cancer, and renal cell carcinoma cell lines, as well as in two renal cell xenograft models. This is an open-label, Phase II study of R935788. Phase I studies in patients with immune thrombocytopenic purpura, rheumatoid arthritis, and lymphoma have demonstrated safety with a continuous dosing schedule, and a maximum tolerated dose has been established. Objectives: To test an experimental drug called R935788 (fostamatinib disodium) for its ability to stop cancer growth signals, thus slowing the growth of cancer cells in laboratory testing. To determine the clinical response of R935788 administered orally twice a day on a continuous schedule in patients with colorectal carcinoma, pheochromocytoma, follicular or papillary thyroid cancer, non-small cell lung cancer, hepatocellular, carcinoma of the head and neck, and renal cell carcinoma. To evaluate the effects, safety, and biochemical response of R935788 therapy. Eligibility: Patients with colorectal carcinoma, pheochromocytoma, follicular or papillary thyroid cancer, non-small cell lung cancer (excluding squamous cell histology), hepatocellular cancer, carcinoma of the head and neck, and renal cell carcinoma whose disease has progressed after any therapy or who have no acceptable standard treatment options. Patients must have recovered from toxicities of prior therapies to at least eligibility levels. Patients who have received radiation or chemotherapy within 4 weeks of study enrollment are not eligible. Women who are pregnant or breastfeeding are not eligible. Design: Researchers will conduct the following tests and procedures during the study: Clinic visits with a physical exam, including vital signs and blood pressure, every other week during cycle 1, and once a month starting with cycle 2. Blood will be drawn weekly during cycle 1, every other week during cycle 2, and once a month starting with cycle 3; urine tests will be conducted depending on results of blood tests. Imaging tests, such as computed tomography (CT) scans (a series of x-rays) or ultrasound (an examination using sound waves), will be done every 8 weeks while the patient is receiving R935788. R935788 will be administered orally twice a day for 28 days (one cycle). Imaging studies will be obtained every two cycles. Patients will fill in a diary to show when they took the medication and to note any side effects. The 28-day treatment cycle will be repeated as long as the patient is tolerating R935788 and the cancer is either stable or getting better. Researchers will conduct the following additional tests to see how the study is affecting the patient: Other research blood samples will be collected before treatment, at cycle 1 week 3, at the beginning of cycle 2, and at 8 weeks. Optional tumor biopsies will be requested before starting treatment, at cycle 1 day 28. Patients with specific lesions or tumors may be asked for an optional tumor biopsy on day 8.

The purpose of this study is to determine efficacy and safety of the biweekly scheme with Capecitabine and Irinotecan, plus bevacizumab in patients with metastatic colorectal cancer.

This 2 arm study will compare the resection rate of liver metastases and safety of surgery in patients with metastatic colorectal cancer and primarily unresectable liver metastases receiving treatment with Avastin in combination with 5-FU, leucovorin and oxaliplatin with irinotecan (FOLFOXIRI) or without irinotecan (mFOLFOX-6) as first line treatment. Patients will be randomized to receive Avastin (5mg/kg iv every 2 weeks) in combination with each of these two standard neoadjuvant chemotherapy regimens. The anticipated time on study treatment is until surgery, disease progression, unacceptable toxicity or patient refusal, and the target sample size is <100 individuals.

This is an open label single arm prospective multicenter Phase II study in around 20 patients. The primary objective of this study is to evaluate whether the addition of sunitinib to FOLFIRI results in a significant reduction of tumor vessel permeability (TVP) and blood flow (BF) measured by DCE-MRI and DCE-USI, measured on liver metastases. Secondary objectives are antitumor response, time to progression (TTP), effect on pharmacokinetics of sunitinib and biomarkers (VEGF und soluble VEGF-receptor) and drug/treatment safety.

The purpose of this study is to determine if IMC-11F8 in combination with chemotherapy is effective in treating colorectal cancer (CRC).

This 2 arm study assessed the efficacy and safety of maintenance treatment with Avastin (bevacizumab) + Xeloda (capecitabine), after initial treatment with Xeloda + oxaliplatin + Avastin, in patients with metastatic colorectal cancer. Patients were randomized into one of 2 groups to receive 1) Xeloda + oxaliplatin + Avastin until disease progression or 2) Xeloda + oxaliplatin + Avastin for 6 3-week cycles, followed by Xeloda + Avastin until disease progression. Xeloda was administered at a dose of 1000 mg/m^2 orally twice a day on days 1-14 of each cycle, oxaliplatin at a dose of 130 mg/m^2 intravenously (iv) on day 1 of each cycle, and Avastin at a dose of 7.5 mg/kg iv on day 1 of each cycle.

RATIONALE: Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving panitumumab together with irinotecan may kill more tumor cells. PURPOSE: This phase II clinical trial is studying giving panitumumab together with irinotecan to see how well it works as third-line therapy in treating patients with metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy, such as irinotecan, oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving combination chemotherapy together with bevacizumab may kill more tumor cells. PURPOSE: This randomized phase III trial is comparing two combination chemotherapy regimens given together with bevacizumab to see how well they work as first-line therapy in treating patients with metastatic colorectal cancer that cannot be removed by surgery.
