Theriva Biologics Announces Appointment of Ramon Alemany, Ph.D., to Senior Vice President of Discovery

-Appointment expected to aid advancement of Theriva’s discovery program and strengthen collaboration with the Institut Catala d’Oncologia (ICO) and the Biomedical Research Institute of Bellvitge (IDIBELL)-

ROCKVILLE, Md., May 23, 2023 (GLOBE NEWSWIRE) — Theriva Biologics (NYSE American: TOVX), (“Theriva” or the “Company”), a clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need, today announced the appointment of Dr. Ramon Alemany as Senior Vice President of Discovery, effective immediately. Dr. Alemany will oversee Theriva’s discovery and development pipeline and will continue to serve as Chair of the Scientific Advisory Board.

Dr. Alemany is Head of the Immunotherapy and Virotherapy Group at the ProCURE Program of the Catalan Institute of Oncology (ICO) and the Oncobell Program of the Biomedical Research Institute of Bellvitge (IDIBELL). Dr. Alemany’s laboratory has developed unique oncolytic adenoviruses that are highly selective for replication in tumor cells, with modifications for tumor-targeting, tumor stroma degradation, evasion of neutralizing antibodies, and promotion of tumor immunogenicity.

“Ramon is an internationally recognized expert in oncolytic adenoviruses and as Co-Founder of VCN Biosciences, is uniquely suited to lead Theriva’s discovery program through its next critical phase of development,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “The acquisition of VCN transformed Theriva’s pipeline, bringing our lead clinical candidate, VCN-01, a systemically administered oncolytic adenovirus designed to selectively replicate within the tumor, remodel the tumor matrix, and increase tumor immunogenicity. As we continue to build on the growing data that underscores VCN-01’s differentiated mechanisms of action, a key priority will be to identify new candidates to leverage the novel Albumin Shield technology and exciting additional technologies from our oncolytic virus (OV) platform. We look forward to Ramon’s guidance and strategic leadership in this new role. Additionally, we are grateful for the opportunity to strengthen our relationship with ICO and IDIBELL, the leading research institutions and long-term collaborators where our current OV technologies and products were invented and incubated.”

Dr. Alemany commented, “It is a privilege to be given the opportunity to expand Theriva’s discovery program and drive forward this new phase of growth. Together with the impressive team at Theriva and ICO/IDIBELL, we will synergistically build upon the foundation of compelling clinical and proof of mechanism data to develop new OVs that may significantly expand the therapeutic indications for our products. Combining novel viral payloads with the proprietary Albumin Shield technology to protect systemically administered oncolytic viruses from the host immune system has tremendous potential for our pipeline.”

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’s wholly-owned Spanish subsidiary Theriva Biologics, S.L., has been developing 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 clinical-stage 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.
