CLS Americas and URN Announce Clinical Study “Targeted MRI/ US Fusion Transperineal Laser Ablation of Low-to-Intermediate Risk Prostate Cancer”

Irvine, California, UNITED STATES

IRVINE, Calif. and MIAMI, March 29, 2022 (GLOBE NEWSWIRE) -- CLS Americas, a subsidiary of Clinical Laserthermia Systems AB, today announced the company’s TRANBERG® Thermal Therapy System will be used by Focalyx Technologies, developer of image-guided fusion target devices, to conduct a 20-patient, Phase I clinical study titled, “Targeted MRI/US Fusion Transperineal Laser Ablation of Low-to-Intermediate Risk Prostate Cancer.” The study will utilize the Focalyx® Fusion medical device for treatment planning, image fusion, real-time image guidance during treatment, and CLS’s TRANBERG® Thermal Therapy System for high-precision, focal laser ablation. Other instruments will be used during the procedure as well. The study will be conducted by Urological Research Network, LLC, a Florida-based, not-for-profit clinical research organization.

“CLS is extremely pleased to begin this important clinical study with Dr. Fernando J. Bianco, the Investigator In-Chief for the Urological Research Network,” stated Michael Magnani, president of CLS Americas. “Dr. Bianco is widely recognized as a pioneer of fusion target therapies in the office setting under local anesthesia and respected throughout the international medical community as an innovative urologic oncologist. We believe this upcoming study will provide strong results showing the safety, efficacy, and effectiveness of treating prostate cancer tumors in an outpatient urology clinic or office setting.” Dr. Bianco began his comprehensive MRI/US, Transperineal Fusion program in 2013 and has since performed over 2,500 biopsies and 1,000 fusion target cryoablations in the office setting.

In the US, over a million prostate biopsies are performed every year identifying almost 250,000 men with prostate cancer. These patients need emergent therapies as alternatives to the standard treatments that often carry long term harmful side effects. CLS is actively recruiting and working with clinical and commercial partners to enable high precision, minimally invasive targeted fusion laser ablation of prostate cancer tumors to be performed under local anesthesia in an office setting or clinic as well as hospitals.

“The role of practical and safe delivery of heat-based tissue ablation applied to malignancies is growing, it’s happening among kidney, lung, and hepatic tumors,” said Dr. Bianco. “We welcome the expansion of ablation energies that can be applied through the perineal skin in an office setting under local anesthesia as novel potential tools in our fight against prostate cancer. However, while I believe there is a tremendous opportunity for laser ablation, it first requires rigorous scientific scrutiny. This trial represents a first solid step in that direction.”

CLS History & Experience – Image-Guided, Focal Laser Ablation of Prostate Tumors
CLS’s TRANBERG® Thermal Therapy System with its accessories have been used to treat hundreds of prostate tumor patients in the US and EU using MRI guidance. The safety and diagnostic accuracy of fusion-guided prostate biopsies are well documented with strong global market growth. The treatment process and workflow for MR/US, fusion-guided focal laser ablation of prostate cancer tumors is very similar to the fusion-guided biopsy process with a similar recovery time for the patient.

High Precision Thermal Therapy System
The TRANBERG® Thermal Therapy System has been developed for image-guided, high-precision soft tissue thermal therapy and ablation procedures. The system can be configured for MR, CT-US, and MR/US, fusion-guided procedures using tissue temperature feedback for precise therapy and ablation control. It includes a desk-top mobile laser unit, innovative non-cooled laser applicators, external tissue temperature probe sensors, and procedure-specific accessories. Its non-cooled, laser fiber technology optimizes heat distribution, eliminates the need for external cooling, and helps reduce procedure times.

Focalyx® Fusion
Focalyx® Fusion is an innovative image fusion medical device. It originated at the University College of London Computational Biology program and has been further developed by Focalyx® Technologies, a Miami-based medical device manufacturing company. The Focalyx® Fusion allows the integration of an MRI diagnostic and treatment plan from magnetic resonance imaging with real-time ultrasound. The contour of the prostate is introduced, and the two silhouettes are superimposed. The result is a highly accurate 3D image of the patient's gland, in which it is possible to locate suspicious lesions with high precision using a GPS-like system. The diagnosed lesion is then ablated safely while preserving the prostate without jeopardizing sexual and urinary functions.

About CLS and the TRANBERG® product portfolio
