(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, announced that the first patients have been dosed in the Company’s Phase 1/2 clinical trial evaluating CYWC628 for the treatment of diabetic foot ulcers (DFUs). Initial dosing took place during the week of June 1, 2026. In parallel with clinical progress, FibroBiologics continues to advance manufacturing of CYWC628 to support ongoing trial activity. Drug product from the Company's second good manufacturing practice (GMP) manufacturing run has been released and is scheduled to ship to Australia during the week of June 15, 2026. FibroBiologics has also completed the manufacturing of the first two batches of its third GMP manufacturing run. “Initiating treatment in our first patients marks the moment our science transitions from the laboratory into the lives of the people in need,” said Pete O'Heeron, Founder and Chief Executive Officer of FibroBiologics. “Fibroblasts are the body's own architects of repair, and CYWC628 is designed to restore the underlying biology that chronic wounds have lost rather than managing symptoms. Successfully advancing our clinical and manufacturing operations in parallel reflects the disciplined execution we set out to deliver.” “Producing consecutive GMP runs of CYWC628 demonstrates that our fibroblast manufacturing platform is reproducible and ready to supply the ongoing clinical trial and beyond,” said Hamid Khoja, Ph.D., Chief Scientific Officer of FibroBiologics. “This consistency is foundational. It provides us confidence both in the integrity of the product reaching patients and our ability to scale for clinical use.” For more information, please visit FibroBiologics' <a href="https://www.globenewswire.com/Tracker?data=Fo_bTivHQJ8RGyUJ9YWL3hRRiqMaGD3WMVGBJzrjAJmH-I_XwvQimLEQXG5BrniCVfSsrTEz6feyH8wXvEEpkA==" rel="nofollow" target="_blank" title="website">website</a>, email FibroBiologics at <a href="https://www.globenewswire.com/Tracker?data=QVntwdyrbihqV7beGre4kgSwSbZOifI3B32Y2EyW0sdgxGa3I-h5Ms5RlKvf8Bxmn-qi0As-jr080VxDVI2pBSK7h8_AeE7GBXv7q_KeaZPj6Sreg_8Hi9CvIcV0MSVnHjcU2C8sY-nZfuCsUEqr9FKTm_CEdDR5PR8fevJqrlq4_24kPjWj5mut-0HilA9egWOTH5nujUts75GeJm1KW_qfoy1oQBZflqMu8r6O4LK9HH4IF-ItI8g4jAz-Jz5GaGnZik8X8i4_kp49vAaBCA==" rel="nofollow" target="_blank" title="info@fibrobiologics.com">info@fibrobiologics.com</a> or follow FibroBiologics on <a href="https://www.globenewswire.com/Tracker?data=gtz6L5zGY18ILpMiHa6C4uP3tYkRwkVBTSqTQcS6QKcYEzF1QomNRnh5JW_dpFAhmOFQMeYMqcpIlHGWQOJg2pJ_rGH0o4egkNhpDDnl7jC0D_06UeM4s9R4M88Om3xk" rel="nofollow" target="_blank" title="LinkedIn">LinkedIn</a>, <a href="https://www.globenewswire.com/Tracker?data=euR38n4VTXypgxTs9YfmWGdkDg3-EE9J89h8f9oHMMVTNV7_zjahuVX-WlZwGCGSed-GKhfJyXnN2PS9BzDqIQsMZVhnmDW2I3PLUx0hWQk=" rel="nofollow" target="_blank" title="YouTube">YouTube</a>, <a href="https://www.globenewswire.com/Tracker?data=RAg-l2o5mLByzXDiTQj7hE4gJ1njFjZPSHrFckEwbA2eDQv32vqFdcgzOBIymdr7KmeNAqWGrPYEQmXjd9kgNQajxSfp_onC2VUU3F9b0nk=" rel="nofollow" target="_blank" title="Facebook">Facebook</a> or <a href="https://www.globenewswire.com/Tracker?data=1SXdcc1B6pkLlZxFZ_wGdUUbezKjsKFp7gnCoSwf_-RkGXgPstGlDlxQzLo_1X-MJiyi_RYFtWBVAP-nY_WFew==" rel="nofollow" target="_blank" title="X">X</a>.
