Trial summary

This phase II trial studies how well internal radiation therapy works in treating patients with low-risk prostate cancer. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. Read more about this study

About this study

Official title: A Phase II Study of Targeted Brachytherapy for Low Risk Prostate Cancer Patients

This phase II trial studies how well internal radiation therapy works in treating patients with low-risk prostate cancer. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine long term 5 year prostate specific cancer (PSA) biochemical control using the Phoenix definition of PSA nadir + 2 of targeted hemi-gland brachytherapy.

SECONDARY OBJECTIVES:

  1. To assess acute and late toxicity outcomes following targeted brachytherapy according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0.

II. To determine changes from baseline in health-related quality of life indicators using the validated Expanded Prostate Cancer Index Composite (EPIC) questionnaire, International Index of Erectile Function (IIEF) questionnaire, and International Prostate Symptom Score (IPSS) questionnaire.

III. To assess the potential value of multiparametric magnetic resonance imaging, including dynamic contrast enhancement perfusion imaging and diffusion tensor neurovascular tactographic imaging in predicting the development of equivocal disease (ED) following radiation treatment.

OUTLINE:

Patients undergo 3 fractions of image-guided high-dose rate (HDR) brachytherapy over 2 days.

After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Biochemical PSA control using the Phoenix definition of PSA nadir + 2

    Measured: 5 years

Secondary outcomes (5)
  1. Grade 3-5 acute toxicity genitourinary (GU) and gastrointestinal (GI) toxicity, graded based on NCI CTCAE v4.0

    Measured: 3 months

  2. Grade 3-5 late toxicity GU and GI toxicity, graded based on NCI CTCAE v4.0

    Measured: 6 months

  3. Changes in health related quality of life (HR-QOL) as determined by EPIC scores

    Measured: Up to 24 months

  4. Changes in HR-QOL as determined by IIEF scores

    Measured: Up to 24 months

  5. Changes in HR-QOL as determined by IPSS scores

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing brachytherapy, image-guided radiation therapy and laboratory biomarker analysis in people with Adenocarcinoma of the Prostate and Recurrent Prostate Cancer, run by Jonsson Comprehensive Cancer Center.

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 10 inclusion and 3 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: withdrawn, as of the sponsor's last update on 27 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

Biochemical PSA control using the Phoenix definition of PSA nadir + 2 (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 27 Jul 2020; AzTrials last refreshed its copy on 6 Nov 2026.
