ROCKVILLE, Md., Aug. 08, 2023 (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 reported financial results for the second quarter ended June 30, 2023, and provided a corporate update.
“We are pleased by the continued progress in the first half of 2023 and look forward to executing on key priorities for our a systemically administered oncolytic adenovirus and lead program, VCN-01, in key indications and therapeutic combinations,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “Notably, we have initiated dosing at U.S. sites for VIRAGE, the Phase 2b trial of VCN-01 in patients with newly-diagnosed metastatic pancreatic ductal adenocarcinoma (PDAC). Dosing in Spain initiated in January 2023 and the first patients have now received their second doses of intravenous VCN-01, which were well tolerated with safety profile consistent with prior clinical trials. VIRAGE remains on track to complete enrollment in the first quarter of 2024. Reaching this critical milestone adds to the strong momentum for the trial and we are further encouraged by the FDA’s decision to grant orphan drug designation to VCN-01 for patients with pancreatic cancer, for which there is an urgent need for new treatment options.”
Mr. Shallcross continued, “We are encouraged by the growing clinical data that underscores VCN-01’s multi-modal mechanism of action, alone or in combination with chemotherapy and immunotherapy products. At the upcoming annual ESMO Congress in Madrid, investigators will present survival data from the ongoing study of VCN-01 in combination with durvalumab in patients with recurrent/metastatic squamous cell carcinoma of the head and neck, which will provide the first clinical insights into the feasibility of combining VCN-01 with an immune checkpoint inhibitor. These results build on the impressive safety, biochemical and mechanistic data presented last year, demonstrating that VCN-01 improved tumor immunogenicity in previously immunotherapy refractory patients. In parallel, we look forward to upcoming discussions with regulatory agencies planned in the second half of 2023 to discuss the development pathway for VCN-01 as an adjunct to chemotherapy in pediatric patients with advanced retinoblastoma. Further, as we continue to explore the potentially broad synergistic clinical benefit of VCN-01, we remain committed to pursuing new oncolytic virus candidates to leverage our novel Albumin Shield technology, which has tremendous potential for our pipeline.”
Recent Program Highlights and Anticipated Milestones:
- Dosing is underway and enrollment continues to progress for VIRAGE, the randomized, controlled, multicenter, open-label Phase 2b trial of VCN-01 in combination with standard-of-care chemotherapy (gemcitabine/nab-paclitaxel) as a first line therapy in newly diagnosed metastatic PDAC patients. Initiated dosing at U.S sites following the initiation of dosing in Spain in January 2023. The first patients in Spain have now received their second doses of intravenous VCN-01, which were well tolerated with safety profile consistent with prior clinical trials. The trial is expected to enroll 92 patients and, remains on track to complete enrollment (Q1 2024).
- The U.S. Food and Drug Administration (FDA) has granted orphan drug designation to VCN-01 for the treatment of pancreatic cancer. Previously, the FDA granted orphan drug designation to VCN-01 for treatment of retinoblastoma.
- The University of Pennsylvania presented initial data from two ovarian cancer patients and one pancreatic cancer patient in their investigator sponsored study combining VCN-01 with huCART-meso cells. The presentation at the Cellicon Valley conference on Thursday 22 June 2023 demonstrated the feasibility of administering VCN-01 with huCART-meso cells and provided evidence of persistence for both VCN-01 and CAR T-cells, supporting the potential opportunity for VCN-01 in combination with immunotherapy products to treat solid tumors.
- Dosing is underway and screening is on-going for the investigator sponsored clinical trial of VCN-01 in patients with high-grade brain tumors who are scheduled for surgical resection. The first patient was dosed in January 2023 and the trial is being conducted at St. James’s University Hospital, United Kingdom, in collaboration with the University of Leeds. If the results show that intravenous VCN-01 gains entry to brain tumors that are otherwise only accessible through surgery, this could be transformative for patients by providing a potential systemic line of treatment.
- Additional anticipated milestones:
- Presentation of data from a Phase 1 investigator-sponsored study evaluating VCN-01 in combination with durvalumab for patients with recurrent/ metastatic squamous cell carcinoma of the head and neck (R/M HNSCC) at the ESMO Congress being held in Madrid, Spain from October 20-24, 2023.
- The Company intends to meet with the FDA (H2 2023) to discuss the clinical development and potential registration pathway for VCN-01 as an adjunct to chemotherapy in pediatric patients with advanced retinoblastoma.
- Dosing is underway for the ongoing Phase 1b/2a randomized, double-blinded, placebo-controlled clinical trial of SYN-004 (ribaxamase) in allogeneic hematopoietic cell transplant (HCT) recipients for the prevention of acute graft-versus-host-disease (aGVHD). SYN-004 appeared to be well tolerated in HCT patients treated with IV meropenem and SYN-004 was not detected in blood samples from the majority of the evaluable patients. The trial is on track to complete the second cohort (Q1 2024)
- In May 2023, appointed Ramon Alemany, Ph.D., to Senior Vice President of Discovery. In addition to overseeing Theriva’s discovery and development pipeline, Dr. Alemany continues 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 Insitute 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.
Second Quarter Ended June 30, 2023 Financial Results
General and administrative expenses increased to $2.7 million for the three months ended June 30, 2023, from $1.5 million for the three months ended June 30, 2022. This increase of 80% is primarily comprised of increased expense related to the fair value of the contingent consideration adjustment of $0.9 million, along with higher audit fees, consulting fees, travel, and VCN administrative expenses not included in the prior year, offset by a decrease in legal costs related to the VCN acquisition. The charge related to stock-based compensation expense was $106,000 for the three months ended June 30,2023, compared to $86,000 for the three months ended June 30, 2022.
Research and development expenses decreased to $3.1 million for the three months ended June 30, 2023, from approximately $3.5 million for the three months ended June 30, 2022. This decrease of 10% is primarily the result of lower expenses related to our Phase 1b/2a clinical trial of SYN-004 (ribaxamase) in allogeneic HCT recipients Phase 1a clinical trial of SYN-020, and decreased manufacturing expenses related to our Phase 1a clinical trial of SYN-020, offset by increased clinical trial expenses related to VCN-01. We anticipate research and development expense to increase as we continue enrollment in our VIRAGE Phase 2 clinical trial of VCN-01 in PDAC, and our ongoing Phase 1 clinical trial in retinoblastoma, expand GMP manufacturing activities for VCN-01, and continue supporting our VCN-11 and other preclinical and discovery initiatives. The charge related to stock-based compensation expense was $40,000 for the three months ended June 30, 2023, compared to $27,000 related to stock-based compensation expense for the three months ended June 30, 2022.
Other income was $377,000 for the three months ended June 30, 2023 compared to other expense of $17,000 for the three months ended June 30, 2022. Other income for the three months ended June 30, 2023 is primarily comprised of interest income of $381,000 and exchange loss of $4,000. Other income for the three months ended June 30, 2022 is primarily comprised of interest income of $26,000 offset by an exchange loss of $9,000.
Cash and cash equivalents totaled $34.2 million as of June 30, 2023, compared to $41.8 million as of December 31, 2022.

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.
