About FBLG
FibroBiologics, Inc. is a clinical-stage biotechnology company. The Company is focused on developing and commercializing fibroblast-based therapies for patients suffering from chronic diseases with significant unmet medical needs, including wound healing, multiple sclerosis, degenerative disc disease, psoriasis and certain cancers, and potential human longevity applications including thymic involution reversal. Its product candidates include CybroCell, CYMS101 and CYWC628. CybroCell is an allogeneic fibroblast cell-based therapy for degenerative disc disease. This technology is being designed as an alternative method for repairing the cartilage of the intervertebral disc (or any other articular cartilage). It is developing CYMS101 as an allogeneic fibroblast cell-based therapy to treat multiple sclerosis (MS) and has completed the Phase I study. It is developing CYWC628 as an allogeneic fibroblast cell-based therapy for wound healing. Its CYPS317 is used for the treatment of Psoriasis.

FibroBiologics Files New Patent for Oral Therapeutics Delivery System
- New Patent Filing: FibroBiologics has filed a new provisional patent application aimed at developing oral fibroblast and fibroblast-derived therapeutics, which could transform the treatment landscape for chronic diseases by enabling targeted delivery through the gastrointestinal tract.
- Multilayer Delivery Architecture: The patent describes a multilayer delivery platform utilizing hydrogels, nanoparticles, and pH-sensitive coatings to ensure therapeutic agents maintain viability against gastric acid and digestive enzymes, thereby enhancing therapeutic efficacy upon release in specific intestinal regions.
- Broad Indications: This platform is applicable to various chronic gastrointestinal disorders, including inflammatory bowel disease, irritable bowel syndrome, and gastrointestinal cancers, indicating its extensive potential in the treatment landscape and the possibility of significantly improving patient quality of life.
- Strategic Implications: The CEO of FibroBiologics noted that a successful oral therapeutic approach would provide a more accessible, non-invasive treatment option, potentially opening a new frontier in fibroblast-based medicine and reinforcing the company's leadership position in the biotechnology sector.

FibroBiologics Reports Positive Results for Burn Treatment
- Preclinical Study Results: FibroBiologics' preclinical study using human dermal fibroblast spheroids for burn treatment demonstrated a significant reduction in inflammation, indicating the therapy's potential in improving burn healing.
- Gene Expression Changes: The study revealed a marked decrease in the expression of collagen synthesis-related genes (Col1a1 and Col3a1) and ECM turnover genes (Mmp1a and Mmp8) in the treatment group, suggesting the therapy may effectively inhibit excessive scarring.
- Immune Response Modulation: Post-treatment, a three-fold decrease in the pro-inflammatory marker interleukin IL-1B and a four-fold increase in the anti-inflammatory cytokine IL-10 were observed, showcasing the therapy's effectiveness in modulating immune responses.
- Market Reaction: Despite FibroBiologics' stock closing down 5.48% at $1.38 on Monday, these positive preclinical results may provide support for future market performance.
