(Nasdaq: FBLG) (“FibroBiologics”), a clinical-stage biotechnology company with 270+ patents issued and pending with a focus on the development of therapeutics and potential cures for chronic diseases using fibroblasts and fibroblast-derived materials, today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for the Company’s patent application entitled “Therapeutic Use of Fibroblasts in Wound Healing.” The allowed application, U.S. Patent Application No. 18/184,726, contains 19 allowed claims directed to methods of treating and accelerating the healing of wounds by topically administering a composition comprising three-dimensional (3D) spheroid fibroblasts together or with one or more fibroblast-derived materials. A Notice of Allowance indicates that the USPTO has completed its examination and intends to grant the patent. Some of the allowed claims include: <ul type="disc"><li style="text-align:justify;">Methods of topically administering 3D spheroid fibroblasts and fibroblast-derived materials into, adjacent to, or on the surface of a wound.</li><li style="text-align:justify;">Treatment of chronic wounds, and of individuals who have diabetes or cancer, or who are immunologically compromised.</li><li style="text-align:justify;">Treatment of wounds including cuts, abrasions, bedsores, and burns.</li><li style="text-align:justify;">Use of activated or manipulated 3D spheroid fibroblasts, including myofibroblasts.</li><li style="text-align:justify;">Methods of accelerating the healing of one or more wounds using the same compositions. </li></ul> The patent aligns closely with FibroBiologics’ lead wound healing program. CYWC628, the Company’s investigational topically administered allogeneic fibroblast-spheroid cell-based therapy, is currently being evaluated in a Phase 1/2 clinical trial in patients with diabetic foot ulcers, among the most common and difficult-to-treat chronic wounds. The newly allowed claims specifically encompass the topical treatment of chronic wounds and of individuals with diabetes, the precise patient population and clinical setting addressed by the CYWC628 program. “This Notice of Allowance is a meaningful recognition of the science underpinning our complete wound care platform,” said Pete O’Heeron, Founder and Chief Executive Officer of FibroBiologics. “It protects the very approach we are now advancing in the clinic with CYWC628 for patients living with diabetic foot ulcers. Securing intellectual property that maps directly onto our lead clinical program strengthens our competitive position and reinforces our belief that fibroblasts, and the materials they produce, can fundamentally change how chronic wounds are treated.” “The allowed claims capture a distinctive feature of our technology, which is the combination of 3D spheroid fibroblasts with or without fibroblast-derived materials such as exosomes and extracellular vesicles,” said Hamid Khoja, Ph.D., Chief Scientific Officer of FibroBiologics. “The examiner specifically recognized that this combination is not taught by the prior art. That distinction is the core belief that our topical fibroblast-spheroid therapy can actively support the biology of wound repair rather than simply manage symptoms, and it provides a strong intellectual property foundation as we generate clinical data.” For more information, please visit FibroBiologics' <a href="https://www.globenewswire.com/Tracker?data=00x_sOo_tn87dkiRjMosWsBpHRoBfe4pzDY2RtKK7LLu3Ppt2ZAriU6kIz1rfMc3HLQ9QM-EKUV8cUD77Nq-SA==" rel="nofollow" target="_blank" title="website">website</a>, email FibroBiologics at <a href="https://www.globenewswire.com/Tracker?data=gThI0-G8ef9RVeLxECIB07bcB_6KCzsPAgOPLhrKpVtenteNUWyMpOnnrCiUeuk2q6TETtapgXkI6vTr3A56Nx84xUiGL4AGBudWRsg49suyr50zq0y_gmYEgaCVQ7Jdpbt-7VvpiXYaVwp0u4P8Xe67DDYF_T2unQdm2XusxcF8-rJvLLnXD4eCaIqzFygbSqE587axTWsxtUzaJw7II_lFCP4ysAkXQ2eQYlZHVmmQAUkmje8lqK6CweW5ddnlaTylxYAj4T47MHNJIUJomg==" rel="nofollow" target="_blank" title="info@fibrobiologics.com">info@fibrobiologics.com</a> or follow FibroBiologics on <a href="https://www.globenewswire.com/Tracker?data=7gfu_zyam9fcQ0zP95QOMMBL-XR_CWbfRePE5hF5ry1JgBm1mQQ7s7VScC0YGPyc0YVrk58qVNZwGAnWI_7pb9Lah2Pxk7kRlt_u3zZ4GLp3KpjWG_rx-_U6KkohxOg3" rel="nofollow" target="_blank" title="LinkedIn">LinkedIn</a>, <a href="https://www.globenewswire.com/Tracker?data=yKXr-wKk39rgoYJ2-57ZVyvsTa8Qye7bjmkguFPiaf95tmgKTDccU0w-Zve6cB6x4X6zgWQrEC9b36dmZ5YT3QrZupgoUTi1ebbr7fHy5x4=" rel="nofollow" target="_blank" title="YouTube">YouTube</a>, <a href="https://www.globenewswire.com/Tracker?data=DC_EV3-j1AaF8kwf8cKx9QWMgXrUCjqZJqYrT4uJF8m8FlMI-Ctmyyx3y6di5iCNU8QJJrap_FW9sngPecNeEUHDkUV_mzP6DRqLpi1TPl8=" rel="nofollow" target="_blank" title="Facebook">Facebook</a> or <a href="https://www.globenewswire.com/Tracker?data=8DgXCuLWgq8uwLV_y4cJobBHbU6Z4ZSJ6dZ3svUMBL0bysUaMCORFj67ogQCC6fbyZKT48g0ZudeEeOYWuyZNQ==" rel="nofollow" target="_blank" title="X">X</a>.
