Olimersen and Irinotecan in Treating Patients With Metastatic or Recurrent Colorectal Cancer
A Phase 1/2 study testing oblimersen sodium and irinotecan hydrochloride in people with Colorectal Cancer, run by The University of Texas Health Science Center at San Antonio at 3 sites in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Gene therapy such as oblimersen may make tumor cells more sensitive to chemotherapy drugs. Combining irinotecan and oblimersen may kill more tumor cells. Read more about this study

About this study
Official title: A Phase I/II, Pharmacokinetic, and Biologic Correlative Study of G3139, NSC # 683428 (Phosphorothioate Antisense Oligonucleotide Directed to Bcl-2) and Irinotecan in Patients With Metastatic Colorectal Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Gene therapy such as oblimersen may make tumor cells more sensitive to chemotherapy drugs. Combining irinotecan and oblimersen may kill more tumor cells.
PURPOSE: Phase I/II trial to study the effectiveness of combining oblimersen and irinotecan in treating patients who have metastatic or recurrent colorectal cancer.
Read the detailed description
OBJECTIVES: I. Determine the dose-limiting toxic effects and maximum tolerated dose of augmerosen (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 after therapy with G3139 at two dose levels and assess the pharmacokinetic and pharmacodynamic correlations.
OUTLINE: This is a dose-escalation, multicenter study. Patients receive augmerosen (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 toxicity. 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing oblimersen sodium and irinotecan hydrochloride in people with Colorectal Cancer, run by The University of Texas Health Science Center at San Antonio at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2013.
