Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
20

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Histologically proven prostate cancer, Gleason Score </=7
  • An anterior visible lesion on mpMRI, that is accessible to IRE treatment
  • Transperineal prostate biopsies (template mapping and/or limited targeted) correlating with clinically significant lesion in the area of the MR-visible lesion (within 2 Barzell zones)
  • Absence of clinically significant disease outside of the planned treatment zone, from histopathology and/or mpMRI findings
  • Stage radiologicalT1-T2cN0M0 disease, as determined by local guidelines
  • Serum PSA </=15 ng/ml
  • Life expectancy of >/= 10 years
  • Signed informed consent by patient
  • An understanding of the English language sufficient to understand written and verbal information about the trial and consent process

Exclusion Criteria:

  • Men who have had previous radiation therapy
  • Men who have had androgen suppression/hormone treatment within the previous 12 months for their prostate cancer
  • Men with evidence of metastatic disease or nodal disease outside the prostate on bone scan or cross-sectional imaging
  • Men with a non-visible tumour on mpMRI
  • Men with an inability to tolerate a transrectal ultrasound
  • Men with latex allergies
  • Men who have undergone prior significant rectal surgery preventing insertion of the TRUS probe (decided on the type of surgery in individual cases)
  • Men who have had previous IRE, HIFU, cryosurgery, thermal or microwave therapy to the prostate.
  • Men who have undergone a Transurethral Resection of the Prostate (TURP) for symptomatic lower urinary tract symptoms within 6 months. These patients may be included within the trial if deferred from consenting and screening until at least 6 months following the TURP.
  • Men not fit for major surgery as assessed by a Consultant Anaesthetist
  • Men unable to have pelvic MRI scanning (severe claustrophobia, permanent cardiac pacemaker, metallic implant etc likely to contribute significant artefact to images)
  • Presence of metal implants/stents in the urethra
  • Men with renal impairment with a GFR of <35ml/min (unable to tolerate Gadolinium dynamic contrast enhanced MRI).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety Profile
Time Frame: Up to 1 year
Number of patients with adverse events using the National Cancer Institute Common Terminology Criteria (NCI CTC) classification system.
Up to 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sexual Side Effects
Time Frame: Up to 1 year
• Change in erectile function measured by the IIEF-15 questionnaire

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
