ROCKVILLE, Md., April 08, 2024 (GLOBE NEWSWIRE) -- Theriva™ Biologics (NYSE American: TOVX), a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need, today announced the presentation of preclinical data demonstrating the potential synergy between lead product candidate, VCN-01 and liposomal irinotecan in a human pancreatic mouse xenograft. Data will be featured in a poster presentation at the American Society for Cell and Gene Therapy (ASGCT) 27^th Annual Meeting, being held both virtually and in Baltimore from May 7-11, 2024.

“We look forward to presenting data at the upcoming ASGCT meeting that further highlight the potential of our systemically administered oncolytic adenovirus, VCN-01, to synergistically combine with an expanding range of standard-of-care chemotherapies for difficult-to-treat cancers,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “ Our on-going VIRAGE Phase 2b trial is evaluating VCN-01 in combination with gemcitabine/nab-paclitaxel to treat metastatic pancreatic ductal adenocarcinoma (PDAC). The enhanced anti-tumor effects observed in the human pancreatic mouse xenograft model with VCN-01 and liposomal irinotecan provides compelling support for evaluating the combination of VCN-01 with the additional first-line pancreatic cancer chemotherapy regimens NALIRIFOX and FOLFIRINOX to provide a portfolio of improved therapeutic combinations for patients with this deadly disease.”

About Theriva™ Biologics, Inc.

Theriva™ Biologics (NYSE American: TOVX), 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 designed for intravenous (IV), intravitreal and antitumoral delivery to trigger tumor cell death, improve access of co-administered cancer therapies to the tumor, and promote a robust and sustained anti-tumor response by the patient’s immune system. The Company’s lead candidates are: (1) 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 significant physical and immunosuppressive barrier to cancer treatment; (2) 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 reducing the incidence and severity of acute graft-versus-host-disease (aGVHD) in allogeneic hematopoietic cell transplant (HCT) recipients; and (3) 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.

In some cases forward-looking statements can be identified by terminology such as “may,” “should,” “potential,” “continue,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” and similar expressions, and include statements regarding the potential synergy between lead product candidate, VCN-01 and liposomal irinotecan in a human pancreatic mouse xenograft and the potential of the Company’s systemically administered oncolytic adenovirus, VCN-01, to synergistically combine with an expanding range of standard-of-care chemotherapies for difficult-to-treat cancers. Important factors that could cause actual results to differ materially from current expectations include, among others, the ability to generate clinical data that establishes VCN-01 may expand the range of standard-of-care chemotherapies for difficult-to-treat cancers; the Company’s and VCN’s product candidates demonstrating safety and effectiveness, as well as results that are consistent with prior results; the ability to complete clinical trials on time and achieve the desired results and benefits; the ability to obtain regulatory approval for commercialization of product candidates or to comply with ongoing regulatory requirements, regulatory limitations relating to the Company’s and VCN’s ability to promote or commercialize their product candidates for the specific indications, acceptance of product candidates in the marketplace and the successful development, marketing or sale of the Company’s and VCN’s products, developments by competitors that render such products obsolete or non-competitive, the Company’s and VCN’s ability to maintain license agreements, the continued maintenance and growth of the Company’s and VCN’s patent estate, the cash runway, and other factors described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 and its other filings with the SEC, including subsequent periodic reports on Forms 10-Q and current reports on Form 8-K.
