MRI Guided Prostate Cancer Focal Laser Ablation

Status Terminated

Clinical Trial Summary

The study is a prospective, single-arm, non-randomized, unblinded trial to determine the safety and efficacy of MRI guided focal laser ablation of localized low and intermediate risk prostate cancer. All subjects meeting the inclusion exclusion criteria and are enrolled will undergo a MRI guided focal laser ablation procedure. The primary aim of the study is to study the safety and efficacy of the procedure.

Clinical Trial Description

Prostate cancer should be viewed as a spectrum of diseases ranging from a very indolent low-risk process to an aggressive high-risk potentially fatal disease. Active surveillance has been introduced as an alternative treatment to patients with low- risk prostate cancers.Focal therapy techniques have been introduced in prostate cancer to destroy the tumor itself with adequate safety margin with the advantage of preserving the surrounding non-cancerous tissue. Thus maintaining disease control at acceptable levels, while minimizing complications.

With the advent of multiparametric MRI (Mp-MRI), it is now possible to identify suspicious prostate gland focal lesions, determining their extent and targeting them for biopsy and focal ablation. Laser interstitial thermal therapy (LITT) is well suited for MRI environment. Laser fibers are flexible so they can fit into the MRI gantry. Laser has been shown to produce homogenous tissue necrosis that can be monitored by real time temperature maps, a feature that facilitates effective and safe ablation.

20 subjects with localized low and intermediate risk prostate cancer that meet the inclusion and exclusion criteria will be enrolled. During baseline evaluation, subjects will undergo lab tests, MR imaging, and will complete QOL questionnaires. Subsequently, subjects will undergo the Magnetic Resonance Imaging (MRI) Guided Focal Laser Interstitial Thermal Ablation procedure. Subjects will be followed immediately after the procedure, at 3 weeks, 3 months, 6 months, one year and two years after procedure for adverse events and recurrence of prostate cancer ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
