The recent FDA clearance of Profound Medical Corp.'s Contouring Assistant AI module for the TULSA-PRO system is a notable advancement in prostate treatment technology. By utilizing a deep learning convolutional neural network with over 24 million parameters, this module aids urologists in creating more accurate treatment designs, thereby improving patient outcomes.

The AI-driven Contouring Assistant not only enhances segmentation accuracy but also significantly speeds up the process, making it 29% faster on average. This is particularly beneficial in clinical settings where time efficiency is crucial. The validation studies, involving multiple renowned radiologists and urologists, show that the tool is on par with expert radiologist performance, a remarkable achievement in medical AI applications.

For the retail investor, this development signifies Profound Medical's commitment to innovation and its potential to capture a significant market share in the prostate treatment landscape. However, it's essential to monitor how swiftly and widely this technology gets adopted in clinical practice.

Financial Analyst

From a financial perspective, the FDA's 510(k) clearance for the Contouring Assistant module is a positive development for Profound Medical Corp. This regulatory milestone could accelerate the adoption of TULSA-PRO systems, potentially increasing the company's revenue streams. The fact that the module has demonstrated significant improvements in efficiency and accuracy could be a strong selling point for healthcare providers.

Moreover, the successful clinical validation and the involvement of esteemed medical professionals lend credibility to the product, which may bolster investor confidence. The emphasis on non-inferior performance compared to expert radiologists and the significant time savings could translate into higher demand and more frequent use, positively impacting Profound Medical’s financial performance in both the short and long term.

However, investors should consider the competitive landscape and the time it takes for new medical technologies to become mainstream. Regulatory clearance is a important step, but market penetration and the resultant financial impact will be the true test.

Market Research Analyst

The introduction of the Contouring Assistant AI module aligns well with current market trends favoring AI-driven medical technologies. The increasing focus on precision medicine and treatment customization is expected to drive demand for such innovative solutions. The TULSA-PRO system’s capability to treat a wide range of prostate conditions with high precision and efficiency positions it strongly within the market.

The FDA clearance acts as a catalyst for market acceptance, potentially increasing Profound Medical's competitive edge. The module's proven effectiveness in independent clinical studies should reassure potential users about its reliability and efficacy. As AI technology continues to evolve, the anticipated improvements in treatment designs could further enhance the system's market appeal.

However, market dynamics such as the availability of competing technologies and reimbursement policies will play a significant role in determining the pace of adoption. Investors should keep an eye on these factors to gauge the long-term impact.

TORONTO, May 14, 2024 (GLOBE NEWSWIRE) -- Profound Medical Corp. (NASDAQ:PROF; TSX:PRN) (“Profound” or the “Company”), a commercial-stage medical device company that develops and markets customizable, incision-free therapies for the ablation of diseased tissue, today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (“FDA”) for the Company’s second TULSA-AI module, Contouring Assistant, for use in conjunction with its TULSA-PRO^® system.

The Transurethral Ultrasound Ablation (“TULSA”) procedure has the potential of becoming a mainstream treatment modality across the entire prostate disease spectrum; ranging from low-, intermediate-, or high-risk prostate cancer; to hybrid patients suffering from both prostate cancer and benign prostatic hyperplasia (“BPH”); to men with BPH only; and also, to patients requiring salvage therapy for radio-recurrent localized prostate cancer. TULSA employs real-time MR guidance for pixel-by-pixel precision to preserve prostate disease patients’ urinary continence and sexual function while killing the targeted prostate tissue via a precise sound absorption technology that gently heats it to kill temperature (55-57°C). TULSA is an incision- and radiation-free “one-and-done” procedure performed in a single session that takes a few hours. Virtually all prostate shapes and sizes can be safely, effectively, and efficiently treated with TULSA. There is no bleeding associated with the procedure; no hospital stay is required; and most TULSA patients report quick recovery to their normal routine.

Recognizing TULSA is being used by urologists to treat an unrivalled variety of prostate cancer and/or BPH patients, Profound is developing a novel set of software modules under the ‘TULSA-AI’ brand to work in conjunction with TULSA-PRO^® to provide further customizability, ease of use, speed of treatment and higher confidence in clinical outcomes.

Contouring Assistant, Profound’s second FDA-cleared TULSA-AI module, is a machine learning-based prostate segmentation tool designed to assist in efficiently delineating the prostate and target ablation volume. This module uses a large database of successful physician-created TULSA treatment designs and recommends a design in a new procedure based upon that knowledge. Moving forward, as the TULSA treatment and outcomes database continues to grow via real-world adoption, and as AI technology evolves, the proposed treatment designs are expected to continue to improve.

In support of the FDA 510(k) application, Contouring Assistant went through rigorous clinical analysis.

First, a Reference Standard was created by combining contours from three expert prostate radiologists: Edward Steiner, MD (WellSpan York Hospital); Steven Raman, MD (UCLA Health); and Robert Princenthal, MD (Rolling Oaks Radiology/RadNet).

Then, Contouring Assistant was validated in two clinical studies:

1. A standalone study in 100 prostate cancer cases, comparing Contouring Assistant to the Reference Standard. This study demonstrated:
   
   
   • Contouring Assistant was non-inferior to the Reference Standard, similar to expert radiologist inter-reader variability; and
   • Contouring Assistant contoured the 100 prostate cases with an average Sørensen–Dice coefficient of 0.910 +/- 0.031.
2. A multi-reader, multi-case (“MRMC”) study was conducted by five prominent radiologists: Pejman Ghanouni, MD, PhD (Stanford Medicine); Aytekin Oto, MD (University of Chicago); Adnaan Moin, MD (WellSpan York Hospital), Sandeep Arora, MBBS (Yale School of Medicine); and Ara Karamanian, MD (HALO Precision Diagnostics). In addition, the same study design was used to assess performance by three renowned urologists: Laurence Klotz, MD (Sunnybrook Health Sciences Centre); Christian Pavlovich, MD (Johns Hopkins University); and Preston Sprenkle, MD (Yale School of Medicine). This MRMC study demonstrated that:
   
   
   • The MRMC readers using Contouring Assistant were non-inferior in terms of contouring accuracy, but also 29% faster on average; and
   • The three urologists who tested this feature showed statistically significant improvement in their segmentation accuracy using Contouring Assistant, and were 32% faster on average.

“Profound is to be commended for supporting this rigorous clinical analysis of the Contouring Assistant feature, which was on par with that normally associated with testing diagnostic-level AI software,” said Dr. Sprenkle. “Importantly, Contour Assistant not only allowed my esteemed urologist colleagues and I to approach the accuracy of an expert radiologist reader in our TULSA treatment designs, but also enabled us to reduce overall procedure times by one-third.”

Arun Menawat, PhD, Profound’s CEO and Chairman, commented, “The addition of a second, FDA-cleared TULSA-AI module is an important milestone as we continue to deliver on our promise to continuously improve the TULSA treatment experience for urologists and their patients. To that end, we believe that Contouring Assistant should not only increase urologists’ confidence in their treatment designs, but also significantly increase their procedural efficiency.”

Profound is continuing development work on the next planned TULSA-AI module, TULSA BPH, and expects to provide more details on that later in 2024.
