Theriva Biologics Inc's stock price increased by 17.80% in pre-market trading as it crossed above the 20-day SMA, indicating strong investor interest.
Despite the overall market decline, with the Nasdaq-100 down 0.92% and the S&P 500 down 0.16%, Theriva's stock movement suggests a sector rotation, possibly driven by positive developments in its pipeline or investor sentiment towards biotech stocks.
This significant price increase may attract further attention from investors and analysts, potentially leading to increased trading volume and interest in the company's future prospects.

About TOVX
Theriva Biologics, Inc. is a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need. The Company is advancing a new oncolytic adenovirus platform. The Company’s candidates are VCN-01, SYN-004 (ribaxamase) and SYN-020. VCN-01, an oncolytic adenovirus designed to replicate selectively and aggressively within tumor cells, and to degrade the tumor stroma barrier that serves as a physical and immunosuppressive barrier to cancer treatment; SYN-004 (ribaxamase) which is designed to degrade certain commonly used IV beta-lactam antibiotics within the gastrointestinal (GI) tract to prevent microbiome damage, thereby limiting overgrowth of pathogenic organisms such as VRE (vancomycin resistant Enterococci), and SYN-020, a recombinant oral formulation of the enzyme intestinal alkaline phosphatase (IAP) produced under cGMP conditions and intended to treat both local GI and systemic diseases.
