About this study

Official title: An Evaluation of Lesion Control Using Focal Ablation With High Intensity Focused Ultrasound in the Treatment of Non-Metastatic Progressive Prostate Cancer

RATIONALE: High-intensity focused ultrasound ablation uses high-energy sound waves to kill tumor cells.

PURPOSE: This phase II trial is studying the side effects of high-intensity focused ultrasound ablation and to see how well it works in treating patients with progressive prostate cancer.

Read the detailed description

OBJECTIVES:

Primary

  • To evaluate the side effects and patient-reported quality of life outcomes of the index (largest) lesion treatment with high-intensity focused ultrasound ablation in patients with progressive ≤ T3b, N0, M0 prostate cancer.

Secondary

  • To determine the success of this treatment by demonstrating the absence of cancer in the treated or ablated area on the 6 month post-treatment transrectal ultrasound biopsy.
  • To evaluate the prostate-specific antigen (PSA) kinetics after index lesion ablation treatment in these patients.
  • To evaluate the proportion of these patients who, after undergoing index lesion control treatment, require androgen blockade at the 12-month follow-up.

OUTLINE: Patients undergo transrectal high-intensity focused ultrasound ablation (HIFU) to the index lesion and other identifiable secondary lesions. Patients are evaluated at 6 months and may repeat HIFU treatment.

Patients undergo MRI and ultrasound at baseline and periodically thereafter, and blood samples are collected periodically for PSA, renal function, full blood count, and testosterone levels. Patients also complete questionnaires (IPSS, IPSS-QOL, ICS, FACT-P, and IIEF-5) at baseline; at 6 weeks; and at 3, 6, 9 and 12 months.

After completion of study treatment, patients are followed at 2 and 6 weeks and at 3, 6, 9, and 12 months.

What is being measured

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

  1. Side effects and patient-reported quality of life after treatment as measured by IPSS, IPSS-QOL, ICS, FACT-P, and IIEF-5 questionnaires at baseline, 6 weeks, and 3, 6, 9 and 12 months

Secondary outcomes (3)
  1. Success of treatment as demonstrated by the absence of cancer at 6 months

  2. PSA kinetics after completion of treatment

  3. Proportion of patients requiring androgen blockade at 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing pharmacological study, questionnaire administration and assessment of therapy complications in people with Prostate Cancer, run by University College London Hospitals at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 26 Aug 2013. 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 Kingdom. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Side effects and patient-reported quality of life after treatment as measured by IPSS, IPSS-QOL, ICS, FACT-P, and IIEF-5 questionnaires at baseline, 6 weeks, and 3, 6, 9 and 12 months. 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 26 Aug 2013.
