Breaking Down Synthetic Biologics, Inc. (SYN) Financial Health: Key Insights for Investors

At the heart of Synthetic Biologics, now operating as Theriva Biologics, is a bold shift toward addressing cancers with high unmet needs through engineered viral therapies and microbiome-protective approaches, marked by the October 2022 rebrand that crystallized a strategic focus on oncolytic adenovirus therapies; the company's lead clinical program, VCN-01, is designed to selectively replicate in tumor cells and degrade tumor stroma to potentiate chemotherapies and immuno-oncology agents, while its earlier program, SYN-004 (ribaxamase), was developed to degrade certain beta-lactam antibiotics in the gut to prevent microbiome damage and downstream infections-tangible examples of a mission to advance intravenous oncolytic viruses and a vision to transform cancer treatment through innovation, guided by core values of integrity, collaboration, and performance-driven quality and compliance that steer the company's clinical and preclinical efforts including the follow-on program VCN-11.

Synthetic Biologics, Inc. (SYN) - Intro

• Mission: Develop targeted biologic therapies that directly modulate tumor microenvironments and protect host microbiomes to improve therapeutic windows and clinical outcomes.
• Vision: Be a leader in next-generation biologics for oncology and microbiome protection, delivering durable value through milestone-driven clinical advancement and partnerships.
• Core values: scientific rigor, patient-centricity, strategic focus, translational innovation, and disciplined capital stewardship.

• Lead program - VCN-01: an oncolytic adenovirus engineered to selectively replicate in tumor cells and express matrix-degrading activities to break down tumor stroma, with the goal of improving distribution and potency of co-administered therapies (chemotherapy, immunotherapy, or targeted agents).
• SYN-004 (ribaxamase): developed to degrade certain IV-administered beta-lactam antibiotics within the gastrointestinal tract to prevent antibiotic-induced microbiome disruption and reduce downstream complications such as Clostridioides difficile infection.
• Strategic emphasis: advancing oncolytic biology while leveraging past microbiome-protective work to inform translational and regulatory strategy.

• Oncology market scale: global oncology therapeutics market exceeds $200 billion annually, with continued double‑digit growth in targeted and biologic segments - a high-value environment for differentiated oncolytic approaches.
• Unmet needs addressed: treatment-refractory solid tumors with dense stroma that limit drug penetration; prevention of antibiotic-driven dysbiosis and downstream infections in hospitalized patients.
• Value-driving milestones: dose-escalation and combination safety data for VCN-01, demonstration of stromal remodeling and enhanced delivery in human tumors, and strategic partnerships or licensing to scale clinical development and commercialization.

• Rebrand (Oct 2022): name change to Theriva Biologics, Inc. formalized a transition from a broader pipeline to a focused oncology-first strategy.
• Capital and execution focus: renewed corporate strategy emphasizes efficient, milestone-driven development to align limited public-company resources with high-impact clinical readouts and potential partner interest.
• Prior program leverage: clinical and translational experience from SYN-004 (ribaxamase) informs regulatory strategy, biomarker development, and patient-safety frameworks for oncolytic programs.
