A Phase 2 study testing docetaxel, prednisone and Radical prostatectomy in people with Prostate Cancer, run by The University of Texas Health Science Center at San Antonio at 1 site in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Read more about this study

About this study
Official title: A Phase II Study to Assess the Feasibility and Activity of Concomitant Radiation and Docetaxel Chemotherapy Followed by Docetaxel Chemotherapy in Prostate Cancer Patients With a Persistent or Rising PSA After Radical Prostatectomy
RATIONALE: Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Docetaxel may make tumor cells more sensitive to radiation therapy. Giving docetaxel together with radiation therapy and prednisone after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This phase II trial is studying how well giving docetaxel together with radiation therapy and prednisone works in treating patients who have undergone surgery for prostate cancer.
Read the detailed description
OBJECTIVES:
Primary
- Determine the rate of prostate-specific antigen (PSA) decline and the number of patients reaching a PSA nadir of zero after treatment with chemoradiotherapy comprising docetaxel and external-beam radiotherapy followed by docetaxel and prednisone in patients with hormone-naive prostate cancer who have a persistent or rising PSA after radical prostatectomy.
Secondary
- Determine the tolerability of this regimen in these patients.
- Determine the progression-free survival, based on PSA progression, of these patients.
- Determine the overall survival of patients treated with chemoradiotherapy for rising PSA after radical prostatectomy.
- Determine if the velocity of subsequent PSA failure impacts survival of these patients.
Tertiary
- Document subsequent therapy for patients whose previous treatment has failed and if there is a response to that therapy.
Quaternary: To collect data on a contemporary cohort to those on study that received radiation alone. We will match cancer and patient characteristics to determine if the variable of chemotherapy has any impact on outcomes.
OUTLINE: Patients receive docetaxel IV over 1 hour on days 1, 8, 15, 22, 29, 36, and 43 and undergo external-beam radiotherapy on days 1-5, 8-12, 15-19, 22-26, 29-33, 36-40, and 43-47.
Beginning within 6 weeks after completion of chemoradiotherapy, patients receive docetaxel IV over 1 hour on day 1 and oral prednisone twice daily on days 1-21. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed at 1 month, every 4 months for 2 years, and then every 6 months for 3 years.
PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing docetaxel, prednisone and Radical prostatectomy in people with Prostate Cancer, run by The University of Texas Health Science Center at San Antonio at 1 site 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?
The sponsor lists 19 inclusion and 14 exclusion criteria. 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: stopped early, as of the sponsor's last update on 8 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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 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?
Yes. Results are posted in the registry (first posted 15 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Rate of Prostate-Specific Antigen (PSA) Decline Reported as the Number of Subjects Reaching a PSA Nadir of Zero Following the Intervention. (time frame: 5 years). It is what the study was designed to measure, not a finding.
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 8 Dec 2017; AzTrials last refreshed its copy on 8 Nov 2026.
