Active clinical trials for "Colorectal Neoplasms"

This study is being done to determine the maximum dose of a certain chemotherapy drug (irinotecan) that can be tolerated as part of a combination of drugs. There is a combination of chemotherapy drugs typically used to treat cancer of the colon and rectum: 5-Flurouracil (5-FU), leucovorin, and irinotecan; the combination is known as FOLFIRI. At the present time, the Food and Drug Administration (FDA) has approved this drug combination for the treatment of cancers of the colon and rectum. The FDA has also approved the use of a drug called bevacizumab (or Avastin) in combination with FOLFIRI, and this is considered one of the standards of care for all patients with colon and rectal cancer which has spread. The best dose of irinotecan to use in the combination of FOLFIRI and bevacizumab is not known. Earlier studies have shown that higher doses of irinotecan can be used safely as part of the FOLFIRI combination, but it is unclear whether these same doses will be safe when bevacizumab is added to this combination.

The primary purpose of this study is to find the highest tolerated dose of the study drugs: capecitabine, oxaliplatin, bevacizumab, and dasatinib given in combination to subjects with advanced solid tumors. This will occur in the first part of the study (Phase I). Once this dose has been determined, it will be given to subjects with advanced metastatic colorectal cancer in the second part of the study (Phase II). By giving these drugs in combination, researchers hope to evaluate the side effects of the study drugs in both groups, and to determine if this combination could possibly decrease or stabilize the cancer being treated. Subjects will be enrolled at Duke University Medical Center (DUMC) and Rocky Mountain Cancer Center. After satisfying eligibility and screening criteria, patients will be treated on 21 day cycles. ABOUT THE STUDY DRUGS Capecitabine (Xeloda™) is an oral (taken by mouth) chemotherapy drug in tablet form made by Roche Laboratories Inc. Capecitabine has been approved for use by the Food and Drug Administration (FDA) for first line treatment (treatment that should be used for cancer that has not been treated yet) of metastatic colorectal cancer and also for metastatic breast cancer. Oxaliplatin (Eloxatin™) is an intravenous (given by injection into a vein) chemotherapy drug made by Sanofi-Synthélabo. This drug is also approved by the FDA for use in metastatic colorectal cancer. Bevacizumab (Avastin™) is a type of intravenous cancer treatment called anti-angiogenic therapy (a type of therapy to treat cancer that interferes with blood flow to the tumor, thereby stopping tumor growth, and possibly leading to tumor shrinkage) made by Genentech Inc. Bevacizumab is approved by the FDA for first line treatment of metastatic colorectal cancer in combination with other chemotherapy. Dasatinib (Sprycel™) is an oral drug made by Bristol Myers Squib, Inc (BMS). Dasatinib is approved by the FDA for the treatment of chronic myeloid leukemia (CML), acute lymphoblastic leukemia or for patients that are resistant to a medicine called imatinib mesylate (Gleevec™ ).

The purpose of the study is to evaluate the efficacy and safety of the capecitabine or 5-fluorouracil selection, according to polymorphisms in TS-3'UTR and ERCC1-118, to be combined with oxaliplatin or irinotecan as first-line chemotherapy in advanced colorectal cancer

The primary objective of this study is to evaluate the efficacy of Irinotecan in combination with FOLFOX+Bevacizumab versus FOLFOX+Bevacizumab alone in the first-line treatment of patients with metastatic colorectal cancer.

The objectives of this study are to evaluate the efficacy and tolerability of single-week regimen of irinotecan plus capecitabine in the first-line or second-line treatment of advanced colorectal cancer.

The purpose of this study is to determine the treatment effect of panitumumab in combination with FOLFOX compared to FOLFOX alone as first line therapy for metastatic colorectal cancer

This single arm study will investigate possible pharmacokinetic interactions between Xeloda and oxaliplatin, and assess whether the pharmacokinetics of Xeloda and/or oxaliplatin is influenced by the addition of Avastin. All subjects will provide samples for pharmacokinetic analysis during the first 3 cycles of treatment. In cycles 1 and 2 patients will receive a treatment regimen containing Xeloda (1000mg/m2 bid) and oxaliplatin (130mg/m2 iv) and in cycle 3 Avastin (7.5mg/kg iv) will be added to the regimen. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

This 2 arm study will compare the pharmacokinetics and safety of Avastin at steady state under 2 different dosing regimens, in combination with XELOX (oxaliplatin + Xeloda) or FOLFOX-4 (oxaliplatin, leucovorin and 5-fluorouracil). Patients randomized to the XELOX arm will receive Avastin (7.5mg/kg iv) on Day 1 of each 3 week cycle; patients randomized to the FOLFOX-4 arm will receive Avastin (5mg/kg iv) on Day 1 of each 2 week cycle. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

This study is for patients with metastatic adenocarcinoma arising from the colon or rectum who have received treatment(s) for metastatic disease with subsequent disease progression. Patients who are intolerant to treatment(s) are also included. This is a study for good performance status colorectal cancer patients who have exhausted standard therapy options.

The purpose of this study is to determine whether CPX-1 is effective in patients with advanced colorectal cancer who have already received chemotherapy that included the drug oxaliplatin or irinotecan. All patients will receive CPX-1 at a dose of 210 units/m2 over 90 minutes every two weeks.
