Technological Edge: Fibroblasts as the Future of Healing

At the core of FibroBiologics' investment thesis is its proprietary fibroblast platform, which differentiates it from traditional cell therapy approaches, particularly those centered on stem cells. Fibroblasts, the most common cell type in the human body, outnumber stem cells by a ratio of 5,000 to one and are inherently stable, accessible, and scalable. This contrasts with stem cells, which are often described as technically complex, unstable, and challenging to harvest, grow, and manufacture at scale.

FibroBiologics' technology leverages these inherent advantages to develop therapies with potentially faster development times, lower costs, and more reliable outcomes. For instance, in preclinical studies for CYWC628, a fibroblast-based spheroid product candidate for wound healing, the company observed a statistically significant acceleration in the rate of wound closure and a statistically significant improvement in the quality of healed wounds when compared to both a marketed wound care product and a control.

The company's research and development initiatives are broad, encompassing several key product candidates:

• CYWC628 (Wound Healing): This topically administered allogeneic fibroblast cell-based therapy is designed for diabetic foot ulcers. The manufacturing of its master and working cell banks is complete and certified.
• CYMS101 (Multiple Sclerosis): An intravenously administered allogeneic fibroblast single cell and spheroid therapy, which has completed a Phase 1 safety study in Mexico.
• CybroCell (Degenerative Disc Disease): An investigational intradiscal administered allogeneic fibroblast cell-based therapy. A significant technological advancement is the confirmation that CYWC628 spheroids can be directly differentiated into chondrocytes, enabling the use of the existing CYWC628 master cell bank for CybroCell manufacturing. This represents a major milestone in platform scalability and efficiency.
• CYPS317 (Psoriasis): An allogeneic intravenously administered fibroblast spheroid cell-based therapeutic.

Beyond these, FibroBiologics is also pursuing early-stage research programs in human longevity, certain cancers, and artificial pancreatic organoids, with plans to accelerate these as funding permits. The company's advancements in its Bone Marrow Organoid platform also show promise for new treatment options in hematopoietic cancers and age-related immune decline. This platform approach, allowing a single core technology to address multiple disease areas, is a critical "so what" for investors, suggesting diversified revenue streams and long-term optionality.

Clinical Pipeline and Strategic Milestones

FibroBiologics is actively translating its fibroblast platform into clinical realities. For CYWC628, the company expects to initiate its twelve-week Phase 1/2 clinical trial for diabetic foot ulcers in Australia in the first quarter of 2026, with completion anticipated in the third quarter of 2026. This timeline, however, has been extended due to process issues with manufacturing training runs and the need for additional aseptic process simulation runs to confirm sterility.

In the multiple sclerosis program, following a successful Phase 1 safety study in Mexico, FibroBiologics plans to file an IND application for a Phase 1/2 clinical trial in the United States in the fourth quarter of 2025. The company also intends to seek a strategic partner for CYMS101's development, either before or after the Phase 1/2 study, prior to a potential Phase 3 trial. For CybroCell, animal trials are underway to confirm the therapeutic equivalence of CYWC628 spheroids to single-cell fibroblasts, which could lead to an amendment of the existing FDA IND clearance to utilize the more scalable spheroid technology. The CYPS317 psoriasis program is also advancing, with IND-enabling animal model studies expected to conclude in the fourth quarter of 2025, paving the way for an IND filing if results are supportive.

Financial Performance and Liquidity: A High-Stakes Development Phase

FibroBiologics operates in a capital-intensive industry, and its financial performance reflects its early-stage development. The company has not generated any revenue from product sales to date and does not anticipate doing so in the foreseeable future. For the three months ended September 30, 2025, FibroBiologics reported a net loss of $5.78 million, a significant increase from $0.50 million in the same period of 2024. The net loss for the nine months ended September 30, 2025, widened to $15.40 million, compared to $8.06 million in the prior year.

This escalating loss is primarily driven by increased research and development (R&D) expenses, which rose by $1.60 million to $2.80 million for the three months ended September 30, 2025, and by $3.50 million to $6.60 million for the nine months ended September 30, 2025. These increases are attributable to higher contract research organization (CRO) costs for clinical trial preparation, cell manufacturing activities, lab facilities expenses, and personnel-related costs due to additional research scientists. General, administrative, and other expenses also saw increases, reaching $2.20 million for the third quarter and $7.40 million for the nine-month period in 2025, primarily due to added personnel and professional fees.

As of September 30, 2025, FibroBiologics held cash and cash equivalents of $4.90 million, a notable decrease from $13.98 million at December 31, 2024. The accumulated deficit stood at $50.90 million. Net cash used in operating activities for the nine months ended September 30, 2025, was $13.20 million, predominantly due to the net losses. Financing activities provided $4.40 million during the same period, mainly from the issuance of short-term convertible debt. The company also recognized net losses of approximately $0.40 million and $0.90 million on the conversion of convertible debt into common stock for the three and nine months ended September 30, 2025, respectively, reflecting the difference between market and conversion prices.

These financial figures underscore a critical liquidity challenge, leading management to conclude there is substantial doubt about the company's ability to continue as a going concern for the next year. While FibroBiologics has implemented measures to reduce operating expenses, including delaying certain R&D projects and limiting administrative costs, its ability to sustain operations and advance its pipeline is heavily dependent on securing additional capital through equity financings, debt, or strategic collaborations.
