Glycogen Storage Disease Type III

– First Level 1 study comparing an emerging technology head-to-head with RP in men with prostate cancer – – TULSA had no blood loss and no overnight stay, along with reduced post-procedure pain, and more rapid recovery to baseline activities and overall health – TORONTO, April 29, 2025 (GLOBE NEWSWIRE) -- Profound Medical Corp. (NASDAQ:PROF; TSX:PRN) (“Profound” or the “Company”), a commercial-stage medical device company that develops and markets customizable, AI-powered, incision-free therapies for the ablation of diseased tissue, is pleased to announce initial perioperative data from the Level 1 post-market CAPTAIN trial comparing the safety and efficacy of the TULSA procedure with radical prostatectomy (“RP”) in men with organ-confined, intermediate-risk, Gleason Score 7 (Grade Group 2 and 3) prostate cancer. The positive perioperative results were presented yesterday by Xiaosong Meng, M.D., Ph.D., an Assistant Professor in the Department of Urology at UT Southwestern Medical Center, at the American Urological Association (“AUA”) Annual Meeting. Starting in 2022, CAPTAIN patients were recruited at 20 sites in the United States, two in Canada and one in Europe. As of January 2025, 201 patients were randomized and, to-date, 194 have been treated or scheduled for treatment (69% TULSA, 31% RP). Baseline patient characteristics are balanced for TULSA vs RP, with median (IQR) age 63 (58-68) vs. 64 (59-68) years, proportions with PSA ≤10ng/mL 77% vs. 74%, and 23% vs 26% with PSA>10ng/mL. Proportions of TULSA vs. RP patients with GG2/3 disease were 76%/24% vs. 74%/26%. All patients were EPIC pad-free at baseline. Dr. Meng’s AUA presentation highlighted that TULSA provided statistically significant improvement in all assessed perioperative measures: Blood loss: TULSA median 0 (IQR 0-0) mL vs. RP 100 (100-200) mL, p<0.001.Length of stay: TULSA median 0.29 (IQR 0.27-0.32) days vs. RP 1.24 (1.12-1.36) days, p<0.001.NRS (Numeric Rating Scale) pain: Significantly lower post-operative pain after TULSA procedure vs. RP through to post-treatment day 6, p<0.05.Patient-reported health-related QOL: Significantly higher overall health on the EQ-5D-5L 0-100 VAS (Visual Analog Scale) after TULSA vs. RP for all 30 days measured after treatment, p<0.05.During the first month post-treatment, significantly fewer TULSA patients reported experiencing extreme problems or inability with mobility (0% for TULSA vs. 12% for RP, p=0.001), self-care (3% for TULSA vs. 17% for RP, p=0.005), and usual activities (17% for TULSA vs. 40% for RP, p=0.008). Dr. Meng commented, “I commend the Sponsor and the Study Investigators for taking on this audacious study, as CAPTAIN is the fist randomized controlled trial comparing a new technology to the standard of robotic radical prostatectomy to successfully recruit to target enrollment. In addition to including some of the most talented and high volume surgeons from academic hospitals and private practice, I believe successful randomization was in large part due to TULSA’s proven safety and efficacy for whole-gland ablation in intermediate-risk prostate cancer patients, which fostered equipoise between both arms. While TULSA already has a well-established body of clinical evidence, it now has hard data that shows quantitatively in a head-to-head fashion significantly superior post-treatment patient experience compared to robotic prostatectomy.” “Zero blood loss and nearly a full 24 hours less at the hospital or clinic. Dramatic reduction in post procedure pain and significant improvement with patient mobility, self-care and ability to perform usual activities,” said Arun Menawat, Profound’s CEO and Chairman. “When we see the data that says that robotic prostatectomy patients take over two weeks of recovery, on average, to feel like a TULSA patient does the day after their procedure, we can understand how TULSA patients are often out at the restaurant with their families the night of their procedure rather than laying in a hospital bed. This superior patient experience leads to high patient satisfaction and patient demand, which interestingly is the same axis that drove adoption of the surgical robot in its early days.” Dr. Menawat added, “We believe the CAPTAIN perioperative outcomes are not only central to patient demand, but are also important for insurance companies who consider Level 1 randomized controlled trials the gold standard in evidence-based research for establishing the effectiveness of interventions and making their coverage policies. We look forward to continue reporting CAPTAIN follow-up data, adding to the growing body of clinical evidence that demonstrates the unrivaled precision and flexibility of TULSA with consistent safe and effective outcomes across the full spectrum of prostate disease states.” About CAPTAIN CAPTAIN (A Comparison of TULSA Procedure vs. Radical Prostatectomy in Participants with Localized Prostate Cancer) is a prospective, multi-center randomized controlled trial aimed at comparing the safety and efficacy of the TULSA procedure (performed with the TULSA-PRO® system) with RP in men with organ-confined, intermediate-risk, Gleason Score 7 (Grade Group 2 and 3) prostate cancer. The goal of CAPTAIN is to demonstrate that the efficacy of the TULSA procedure is not inferior to RP, while demonstrating superior quality of life outcomes. The primary safety endpoint is the proportion of patients who preserve both erectile potency and urinary continence at one year after treatment. The primary efficacy endpoint is the proportion of patients who are free from any additional treatment for prostate cancer, free of metastases or prostate cancer related death by three years after treatment. Secondary endpoints include comparison of rates of complications, cost effectiveness, as well as histologic and biochemical failure. About Profound Medical Corp. Profound is a commercial-stage medical device company that develops and markets customizable, incision-free therapies for the ablation of diseased tissue. Profound is commercializing TULSA-PRO®, a technology that combines real-time MRI, AI-enhanced planning, robotically-driven transurethral ultrasound, and closed-loop temperature feedback control. The TULSA procedure, performed using the TULSA-PRO® system, 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 precision to preserve patients’ urinary continence and sexual function, while killing the targeted prostate tissue via precise sound absorption technology that gently heats it to 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. TULSA-PRO® is CE marked, Health Canada approved, and 510(k) cleared by the U.S. Food and Drug Administration (“FDA”). Profound is also commercializing Sonalleve®, an innovative therapeutic platform that is CE marked for the treatment of uterine fibroids and palliative pain treatment of bone metastases.

As several well-funded companies race to make generative AI models that can design new protein therapies from scratch , one small startup has found a new use for existing AI systems: compressing large proteins to better package them in gene therapies or deliver them to hard-to-reach places like the back of the eye. The startup, called ZipBio, has raised $4 million in seed funding for the idea, it told Endpoints News exclusively. “The inspiration came from the compression of technology in the digital world,” CEO Roee Farber said in an interview. Of course, shrinking the structure of a protein and retaining its function isn’t as simple as compressing digital documents into a zip file. The startup is trying to isolate small parts of proteins that are most important for making a drug and shave off the rest. The problem is that the rest of the protein is there for a reason. Removing it can cause the entire thing to collapse. ZipBio’s solution is to use generative AI to create a new backbone that holds that key part of the protein in place. “In the past, nobody succeeded with that. Now it’s something we can do relatively trivially,” Farber said. The company hasn’t published details about how its approach works, but Farber said ZipBio is using and refining publicly available AI models for protein design, rather than creating its own. The startup was founded in 2023, began work on its lead drug just eight months ago, and is already testing it in animals, Farber said. That drug candidate builds on Regeneron’s antibody Eylea as a starting point — an eye therapy that made the company $5.89 billion last year. Eylea inhibits two forms of VEGF, a protein that can spur unwanted blood vessel growth in the eyes. But just blocking the A and B forms of the protein doesn’t fully treat everyone. ZipBio has created a compact inhibitor of VEGF-C and VEGF-D and meshed it with Eylea, using AI to create a hybrid molecule that Farber says is compact enough to travel to the back of the eye, something that a simple fusion of two full antibodies likely wouldn’t do. Clinical trials could begin as soon as 2026. The startup is also working with the French nonprofit Généthon to create a compact version of a protein that’s too big to fit into AAVs — the most common viral vectors used in gene therapy — to treat a rare disease called glycogen storage disorder III, a form of muscular dystrophy. ZipBio’s seed funding was led by NFX, a venture capital firm that invests in tech startups at a seed stage or earlier. MoreVC, which focuses on early-stage Israeli tech startups, also contributed. ZipBio’s team of 12 is currently split between Seattle and Tel Aviv, Israel.

HYOGO, Japan--( BUSINESS WIRE )-- JCR Pharmaceuticals Co., Ltd. (TSE 4552; Chairman and President: Shin Ashida; “JCR”) announced today the completion of the regulatory review by the Pharmaceuticals and Medical Devices Agency (PMDA) for the clinical trial notification for the Phase I study of JR-441 in individuals with mucopolysaccharidosis type IIIA (MPS IIIA; Sanfilippo syndrome type A). JR-441 is a recombinant form of heparan N-sulfatase that is developed using JCR’s proprietary J-Brain Cargo ® blood-brain barrier (BBB)-penetrating technology. JR-441 addresses a significant unmet medical need by crossing the BBB and targeting the neurological symptoms of MPS IIIA within the central nervous system. "MPS IIIA is a rare and life-threatening lysosomal storage disorder for which there are currently no approved treatment options for individuals living with this devastating disease, and there is a dire need to address the neurological signs and symptoms of MPS IIIA,” said Shin Ashida, Chairman and President of JCR Pharmaceuticals. “We are pleased that the PMDA’s review of the Phase I study plan is complete, and that clinical development program is progressing. We are committed to continuing to advance the JR-441 clinical development program with the goal of meeting the unmet medical needs of this patient community. We look forward to sharing updates on the program when they are available.” The European Commission (EC) and the U.S. Food and Drug Administration (FDA) granted JR-441 orphan drug designation (ODD) for the treatment of MPS IIIA. JR-441 is currently being studied in an ongoing Phase I/II clinical trial in Germany (JR-441-101, NCT06095388 ), apart from this Japanese Phase I study. The impact of this announcement on JCR's consolidated financial results for this fiscal year (ending March 2025) is expected to be minor. About Mucopolysaccharidosis Type IIIA (Sanfilippo Syndrome Type A) Mucopolysaccharidosis type IIIA, or Sanfilippo syndrome type A, is an autosomal recessive disease caused by pathogenic mutations in the SGSH gene, encoding a lysosomal enzyme involved in the degradation of heparan sulfate. The accumulation of heparan sulfate in several types of cells of the body, especially in the central nervous system in the brain, results in severe neurological deterioration, cognitive impairment, mild somatic involvement, and shortened lifespan.
