(NASDAQ: CELZ) ("Creative Medical" or the "Company"), a clinical-stage biotechnology company advancing regenerative medicine solutions, today announced the filing of a new U.S. provisional patent application designed to expand intellectual property protection surrounding Ultrasome™, the Company’s proprietary cell-free regenerative medicine platform. The newly filed application builds upon Creative Medical’s existing regenerative medicine intellectual property and seeks protection across multiple aspects of the Ultrasome platform, including proprietary product composition, biological potency, manufacturing and quality-control methodologies, stability characteristics, delivery approaches and therapeutic applications. The filing is intended to strengthen the Company’s long-term intellectual property position as Creative Medical advances Ultrasome beyond its initial osteoarthritis program and evaluates the platform’s potential across additional areas of regenerative medicine. “As our understanding of the Ultrasome platform continues to advance, we believe it is important to protect not only its therapeutic applications, but also the underlying product characteristics, biological activity and manufacturing framework that distinguish the platform,” said Timothy Warbington, President and Chief Executive Officer of Creative Medical Technology Holdings. “This filing represents another step in building a broad intellectual property estate around what we believe can become a highly scalable cell-free regenerative medicine platform.” Building Intellectual Property Around Product Function, Not Simply Particle Identity Creative Medical’s development strategy for Ultrasome incorporates both physical product characterization and biologically relevant functional testing designed to evaluate activity associated with tissue protection and regenerative signaling. The newly filed provisional patent application seeks intellectual property protection around multiple aspects of this approach, including methods intended to characterize the biological activity and consistency of manufactured product. Management believes that integrating product composition, functional potency and manufacturing control may provide important differentiation as the field of extracellular-vesicle and secretome-based therapeutics continues to evolve. The patent application also includes intellectual property directed toward methods for evaluating changes in product biological activity that may not be reflected by particle measurements alone. “A central component of our development strategy is establishing reproducible biological activity across manufactured product,” Warbington added. “We believe that connecting manufacturing, product characterization and functional performance is important both scientifically and strategically as we advance this platform.” Builds on Previously Announced Ultrasome™ Knee Osteoarthritis Program The new patent filing follows Creative Medical’s previously announced pilot study evaluating Ultrasome in patients with knee osteoarthritis. As announced in April 2026, the study reported that approximately 93% of participants demonstrated clinically meaningful improvements in mobility and pain, and no serious adverse events were reported. The Company continues to view osteoarthritis as an important initial application for Ultrasome while exploring the broader potential of the platform across regenerative medicine. The new provisional filing includes intellectual property intended to preserve development flexibility for musculoskeletal and cartilage disorders as well as selected clinical applications. These additional applications remain in various stages of research and development and should not be interpreted as evidence of clinical efficacy or regulatory approval in those indications. Extending a GMP-Based Regenerative Medicine Platform Ultrasome is being developed from Creative Medical’s proprietary Olastrocel™ regenerative medicine platform. The underlying cellular source is derived from an independently validated Good Manufacturing Practice master cell bank, with manufacturing and quality information maintained within a U.S. Food and Drug Administration Drug Master File. A Drug Master File is a confidential regulatory submission containing manufacturing and quality information and does not itself constitute FDA approval, clearance or authorization of a therapeutic product. Creative Medical believes the ability to leverage a controlled cellular starting material across both cell-based and cell-free programs may support future manufacturing scalability, product consistency and expansion of its regenerative medicine pipeline. Expanding Creative Medical’s Intellectual Property Portfolio The new application is part of Creative Medical’s strategy of building intellectual property protection around multiple layers of its regenerative medicine technologies, including: <ul><li>proprietary cell-free compositions;</li><li>functional biological characteristics;</li><li>manufacturing and quality-control methodologies;</li><li>stability and product-release approaches;</li><li>targeted delivery methods; and</li><li>therapeutic applications across selected regenerative medicine indications. </li></ul> As a provisional patent application, the filing establishes an initial U.S. priority date for the disclosed subject matter and provides the Company with the opportunity to pursue U.S. and international patent protection through subsequent filings. The provisional application has not been examined by the U.S. Patent and Trademark Office, and there can be no assurance regarding the scope or issuance of any future patent claims. Strategic Focus Creative Medical intends to continue advancing its intellectual property portfolio in parallel with its clinical and translational development programs. Management believes a combination of clinical development, proprietary manufacturing, functional product characterization and intellectual property protection may create multiple opportunities for future platform development, strategic collaboration and value creation. “Our goal is to build durable value around the science,” Warbington concluded. “We believe the combination of our clinical-stage regenerative platform, expanding cell-free programs and growing intellectual property portfolio positions Creative Medical to pursue multiple high-value opportunities while maintaining disciplined development of our core programs.” About Ultrasome™ Ultrasome™ is Creative Medical Technology Holdings’ proprietary cell-free regenerative medicine platform derived from the Company’s umbilical cord tissue technology. The platform is being developed to deliver biologically active regenerative signals through scalable, off-the-shelf formulations for potential use across selected degenerative and regenerative medicine applications. Ultrasome’s initial clinical development has focused on osteoarthritis of the knee. About Creative Medical Technology Holdings, Inc. Creative Medical Technology Holdings, Inc.
