Focal Laser Ablation of Prostate Cancer

Status Active, not recruiting

Clinical Trial Summary

The primary objective of this study is to evaluate the safety and feasibility of Magnetic-Resonance(MR)-ultrasound image fusion-guided transrectal-based focal laser ablation (FLA) of prostate cancer using the Orion System, an investigational laser-based interstitial irradiation/thermal soft-tissue ablation system. Safety and feasibility will be determined by analyzing the number, type, and severity of adverse events.

Clinical Trial Description

The primary objective is to evaluate the safety and feasibility of MR-ultrasound image fusion-guided transrectal-based focal laser ablation (FLA) of prostate cancer using the Orion System, an investigational laser-based interstitial irradiation/thermal soft-tissue ablation system. Safety and feasibility will be determined by analyzing the number, type, and severity of adverse events. In addition, changes in health-related quality of life (HRQOL) will be evaluated using Expanded Prostate Index Composite for Clinical Practice (EPIC-CP), Memorial Anxiety Scale for Prostate Cancer (MAX-PC), and Decision Regret Scale. This is an open-label early feasibility/pilot study to evaluate the safety and feasibility of the Orion System. In this study, the investigators intend to use the investigational Orion system to deploy and monitor thermal energy in cancerous regions of the prostate, identified by MRI and confirmed by targeted biopsy. MRI guidance will be achieved by MRI/ultrasound fusion, overlaying stored MRI images upon real-time ultrasound images. Interstitial laser treatments would be achieved by inserting the fiber into the cancerous regions guided by the Artemis image-fusion device. Applications of laser energy up to 15 watts of power will be used to treat the target region. Subjects will return to clinic 1 week, 1 month, and every 3 months until one year post-FLA to be monitored for adverse events and complete Health Related Quality of Life (HRQOL) questionnaires. Biomarker (PSA) kinetics will also be monitored. ;

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.
