G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer Clinical Trials Facts presented on Clinical Trials Search isn't designed to be a substitute for proven healthcare advice, calls or treatment by using a genuine medical doctor. We aren't mDs. Always confer with your doctor on G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer Clinical research trials and G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer healthcare trials occur in a lot of of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectivity of new does drugs. The role of the studies / undertakings is to solve specific human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to find treatments for all kinds of conditions, including G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer. G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer Clinical Trials and other clinical trials allow for volunteers to access health treatment choices before they are available to the general public. Many times the test subjects get treatment for without cost, and sometimes they are compensated for their time. Occasionally there is a cost for a G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer clinical trial. Test subjects typically receive the most effective healthcare possible for their G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer condition. Risks are a reality, nonetheless, and could include extra or frequent dr. calls, health hazards (perhaps life-jeopardizing), and/or the treatment being ineffective. Trials are federally regulated with rigid guidelines to protect clinical trials subjects.

G3139 and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer
For Condition: recurrent colon cancer,Stage 4 rectal cancer,stage 4 colon cancer,adenocarcinoma of the colon,recurrent rectal cancer,adenocarcinoma of the rectum
Status: Completed
Sponsor(s): National Cancer Institute (NCI) , San Antonio Cancer Institute
Synopsis: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Gene therapy such as bcl-2 antisense oligodeoxynucleotide G3139 (G3139) may make tumor cells more sensitive to chemotherapy drugs. Combining irinotecan and G3139 may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combining G3139 and irinotecan in treating patients who have metastatic or recurrent colorectal cancer.
Details: OBJECTIVES: I. Determine the dose limiting toxicities and maximum tolerated dose of bcl-2 antisense oligodeoxynucleotide G3139 (G3139) administered in combination with irinotecan in patients with unresectable metastatic or recurrent colorectal cancer. II. Determine the quantitative and qualitative toxicity of this drug combination in this patient population. III. Assess the plasma pharmacokinetics of this combination in these patients. IV. Document the antitumor activity of this drug combination in these patients in a phase II study. V. Determine the relevant biologic endpoints of treatment in tumor biopsies prior to and following therapy with G3139 at two dose levels and assess the pharmacokinetic and pharmacodynamic correlations. PROTOCOL OUTLINE: This is a dose escalation, multicenter study. Patients receive bcl-2 antisense oligodeoxynucleotide G3139 (G3139) IV continuously on days 1-7 and irinotecan IV over 90 minutes on day 6. Treatment continues every 21 days in the absence of unacceptable toxicity or disease progression. Cohorts of 3-6 patients receive escalating doses of G3139 and irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicities. Once the MTD is determined, additional patients are accrued to receive treatment with G3139 and irinotecan at the recommended phase II dose. Patients are followed every 30 days until toxicity resolves. PROJECTED ACCRUAL: A maximum of 18 patients will be accrued for the phase I portion of this study. A maximum of 55 patients will be accrued for the phase II portion of this study.
