HOUSTON, May 05, 2026 (GLOBE NEWSWIRE) -- FibroBiologics, Inc. (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 issued the following letter to shareholders.

Dear Fellow Shareholders,

This year, FibroBiologics achieved a milestone we have been working toward over the past few years. We initiated our clinical trial for our lead program, CYWC628, an investigational fibroblast-based therapy for diabetic foot ulcers (DFUs).

After years of building the technology and infrastructure to support it, progressing into the clinic is a critical step for us. It demonstrates the dedicated work across the team and signifies an important transition from development into clinical execution.

DFUs remain an underserved condition in medicine. More than 33 million patients worldwide are affected, yet current treatment options continue to fall short, with amputation and recurrence rates that have seen little improvement over time. CYWC628 is designed to address this by harnessing the unique regenerative and immune-modulating properties of fibroblasts. We are now evaluating its clinical benefit potential in patients. This program represents not only a near-term opportunity, but also a first step in demonstrating the broader applicability of our platform and the potential to derisk for future indications and applications.

We have a clear set of imminent clinical milestones that will guide this program. We have completed initial site activation and will begin patient enrollment in Q2 of 2026. Our focus will be on generating data that validates the efficacy and safety as the trial progresses, resulting in a topline data readout that can inform the next phase of clinical development by the end of 2026. Each of these steps is designed to reduce risk and build a strong clinical foundation for CYWC628.

Our current capital plan provides us with the resources to operate through topline data from this trial. This allows our team to remain focused on disciplined execution by advancing the study, generating high-quality data, and reaching a meaningful clinical readout.

While CYWC628 is our priority, we continue to progress across the broader pipeline. Our programs in multiple sclerosis and psoriasis are advancing, supported by ongoing preclinical work, and our artificial thymus organoid platform continues to generate data that we believe may support an entirely new approach to restoring immune function. Each of these programs reflects our strategy of targeting diseases where cellular dysfunction plays a central role and where our technology may offer a differentiated approach.

Last year, I said we were building something enduring. This year, we are beginning to demonstrate it with a clear clinical pathway, a focused strategy, and the resources to execute.

Thank you for your continued support and confidence in what we are building.

Best regards,
