- Data to be presented in a poster session at the American Association of Cancer Research (AACR) Annual Meeting in San Diego, California on Monday April 20, 2026-
Rockville, MD, April 17, 2026 – Theriva™ Biologics (NYSE American: TOVX), (“Theriva” or the “Company”), a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need, today announced an upcoming poster presentation of new data and subgroup analyses from the VIRAGE Phase 2b clinical trial evaluating VCN-01 (zabilugene almadenorepvec) plus gemcitabine/nab-paclitaxel in newly-diagnosed metastatic pancreatic cancer patients.

“The new data and analyses to be presented at the AACR meeting further reinforce our confidence in the clinical potential of VCN-01 plus gemcitabine/nab-paclitaxel chemotherapy to help metastatic PDAC patients,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “Taken together, the tumor response and biomarker data support an immune-mediated mode of action for VCN-01, which is consistent with the previously reported clinical observations, showing that patients treated with VCN-01 plus gemcitabine/nab-paclitaxel experienced a significantly protracted duration of response concomitant with a later-stage prolongation of survival compared to patients treated with gemcitabine/nab-paclitaxel alone. We have achieved alignment with both the FDA and the EMA on a proposed pivotal Phase 3 clinical trial to evaluate multiple doses of VCN-01 plus gemcitabine/nab-paclitaxel in first-line metastatic PDAC patients, and we are planning a small study to assess whether more frequent and extended VCN-01 dosing could further improve outcomes.”
About Pancreatic Ductal Adenocarcinoma
Cancer of the pancreas consists of two main histological types: cancer that arises from the ductal (exocrine) cells of the pancreas or, much less often, cancers may arise from the endocrine compartment of the pancreas. Pancreatic ductal adenocarcinoma (“PDAC”) accounts for more than 90% of all pancreatic tumors. It can be located either in the head of the pancreas or in the body/tail. Pancreatic cancer usually metastasizes to the liver and peritoneum. Other less common metastatic sites are the lungs, brain, kidney, and bone. In its early stages, pancreatic cancer does not typically result in any characteristic symptoms. In many instances, progressive abdominal pain is the first symptom. Therefore, in most cases, pancreatic cancer is diagnosed in its late stages (locally advanced non-metastatic or metastatic stage of the disease) when surgical resection and possibly curative treatment is not possible. It is generally assumed that only 10% of cases are resectable at presentation, whereas 30-40% of patients are diagnosed at local advanced/unresectable stage and 50-60% present with distant metastases.
About VCN-01
VCN-01 (zabilugene almadenorepvec) is a systemically administered oncolytic adenovirus designed to selectively and aggressively replicate within tumor cells and degrade the tumor stroma that serves as a significant physical and immunosuppressive barrier to cancer treatment. This unique mode-of-action enables VCN-01 to exert multiple antitumor effects by (i) selectively infecting and lysing tumor cells; (ii) enhancing the access and perfusion of co-administered chemotherapy products; and (iii) increasing tumor immunogenicity and exposing the tumor to the patient’s immune system and co-administered immunotherapy products. Systemic administration enables VCN-01 to exert its actions on both the primary tumor and metastases. VCN-01 has been administered to 142 patients to date in clinical trials of different cancers, including pancreatic ductal adenocarcinoma (in combination with chemotherapy), head and neck squamous cell carcinoma (with an immune checkpoint inhibitor), ovarian cancer (with CAR-T cell therapy), colorectal cancer, and retinoblastoma (by intravitreal injection). More information on these clinical trials is available at Clinicaltrials.gov.
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 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 is VCN-01 (zabilugene almadenorepvec), 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. An exploratory clinical trial is also on-going with 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.

VCN-01 is a clinical-stage oncolytic adenovirus engineered to replicate selectively in cancer cells with an aberrant RB1-E2F pathway. The VCN-01 E1A promoter is modified by inclusion of eight E2F1 binding sites and a 24-bp deletion that promotes viral transcription in cells with elevated free E2F1 and renders the virus replication-deficient in RB1-functional, normal cells. Here, human pancreatic cancer cell lines were exposed to topoisomerase I (topo1) inhibiting chemotherapeutics, irinotecan (IRI), its active metabolite, SN-38, and topotecan (topo; see Figure A). Notably, in NP-18 cells, E2F1 mRNA was increased ~3-fold compared to untreated cells, and E1A mRNA was boosted ~5-fold in cells treated with VCN-01 + topo1 inhibitors compared to VCN-01 alone. These data suggest that topo1 inhibitor-mediated elevations in E2F1 increase VCN-01 transcription. Based on these promising in vitro results, the potential synergy of VCN-01 plus the liposomal formulation of IRI ( B A C K G R O U N D Zabilugene almadenorepvec (VCN-01) 1 is an oncolytic adenovirus engineered to replicate in cancer cells with a dysfunctional RB1 pathway. VCN-01 expresses PH20 hyaluronidase to improve intratumoral viral dissemination, enhance chemotherapy penetration, and facilitate immune cell infiltration. Previous phase I showed that intravenous administration of VCN-01 is feasible and has an acceptable safety profile2 . VCN-01 reached and replicated in tumors, induced an inflammatory tumor microenvironment, and showed encouraging biological and clinical activity when administered sequentially with GnP to patients with mPDAC. In this phase IIb VIRAGE trial, the primary endpoints of overall survival (OS) and safety were accomplished (previously presented at ESMO 2025) 3 . Figure 1. Mechanisms of action of VCN-01 Chemonaïve mPDAC patients were randomized 1:1 to receive GnP on days 1, 8 and 15 of repeated 28-day cycles (GnP group) or 2 separate IV doses of VCN-01 (1x1013 vp/dose) 1 week prior to cycles 1 and 4 of GnP (VCN-01 + GnP group). • Primary endpoints: • Overall survival (OS) • Safety and tolerability • Secondary objectives: • Progression free survival (PFS) • Objective response rates (ORR) • Disease control rate (DCR) • Duration of response (DoR) • Changes of CA 19-9 over time • Exploratory analyses: • Viral genomes (vg) in blood • Neutralizing antibodies (NAbs) in serum Figure 2.
