GTI-2040, Docetaxel, and Prednisone in Treating Patients With Prostate Cancer
A Phase 2 study testing GTI-2040, docetaxel and prednisone in people with Prostate Cancer, run by University Health Network, Toronto at 5 sites in Canada.
Trial summary
RATIONALE: GTI-2040 may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Read more about this study

About this study
Official title: A Phase II Study of GTI-2040 in Combination With Docetaxel and Prednisone in Hormone-Refractory Prostate Cancer
RATIONALE: GTI-2040 may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. GTI-2040 may help docetaxel kill more tumor cells by making them more sensitive to the drug.
PURPOSE: This phase II trial is studying how well giving GTI-2040 together with docetaxel and prednisone works in treating patients with prostate cancer that has not responded to hormone therapy.
Read the detailed description
OBJECTIVES:
Primary
- Determine the efficacy of GTI-2040, docetaxel, and prednisone, in terms of prostate-specific antigen (PSA) response rate, in patients with hormone-refractory prostate cancer.
Secondary
- Determine objective tumor response in patients treated with this regimen.
- Determine the median time to progression in patients treated with this regimen.
- Determine the safety and tolerability of this regimen in these patients.
- Determine the median duration of PSA response in patients treated with this regimen.
- Correlate baseline and post-treatment levels of ribonucleotide reductase activity in tumor biopsies and peripheral blood mononuclear cells and tumoral expression of c-myc, R2 subunit protein, and markers of cellular proliferation and apoptosis with clinical outcomes in patients treated with this regimen.
OUTLINE: This is an open-label, multicenter study.
Patients receive GTI-2040 IV continuously on days 1-14, docetaxel IV on day 3 of course 1 and on day 1 of subsequent courses, and oral prednisone twice daily on days 1-21. Treatment repeats every 21 days for up to 10 courses in the absence of disease progression or unacceptable toxicity.
Patients are followed for survival.
PROJECTED ACCRUAL: A total of 18-46 patients will be accrued for this study within 3.6-9.5 months.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing GTI-2040, docetaxel and prednisone in people with Prostate Cancer, run by University Health Network, Toronto at 5 sites in Canada.
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 28 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Canada. 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 phase mean?
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.
What does the primary outcome measure?
PSA response rate. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00087165, which also lists 1 linked publication.
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 28 Apr 2021.
