Theriva™ Biologics Reports First Quarter 2024 Operational Highlights and Financial Results
Theriva™ Biologics, a clinical-stage company, reported positive results from a Phase 1 trial for VCN-01 in pediatric patients with retinoblastoma and presented preclinical data on VCN-01's potential in pancreatic cancer treatment. The Phase 2b trial for VCN-01 in metastatic Pancreatic Ductal Adenocarcinoma (PDAC) is expected to complete enrollment soon. The company has $18.3 million in cash as of March 31, 2024, providing runway into Q1 2025.
Positive results from Phase 1 trial for VCN-01 in pediatric patients with refractory retinoblastoma, showing therapeutic potential and synergy with chemotherapy.
Preclinical data presented at ASGCT Annual Meeting highlighting VCN-01's potential in diverse chemotherapy combinations for improved efficacy in pancreatic cancer.
Phase 2b clinical trial of VCN-01 in combination with chemotherapy for metastatic PDAC on track for completion of enrollment in Q3 2024.
$18.3 million in cash as of March 31, 2024, providing financial runway into the first quarter of 2025.
Research and development expenses increased to $3.5 million for the three months ended March 31, 2024, primarily due to higher clinical trial expenses, potentially impacting profitability.
General and administrative expenses decreased to $1.9 million for the same period, reflecting cost-saving measures but also a decrease in fair value of contingent consideration adjustment.

ROCKVILLE, Md., May 07, 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 reported financial results for the first quarter ended March 31, 2024, and provided a corporate update.
“In the first quarter we reported positive topline data from the investigator sponsored Phase 1 trial in patients with refractory retinoblastoma, further validating VCN-01’s unique mechanism of action and therapeutic potential to improve treatment outcomes as an adjunct to chemotherapy in this area of high unmet need,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “In parallel, we continue to build a portfolio of potentially improved therapeutic combinations for PDAC patients. VIRAGE, our Phase 2b trial evaluating VCN-01 in metastatic PDAC is progressing and enrolling patients across sites in the U.S. and Spain. Further, the recently presented preclinical data at ASGCT support the potential antitumor synergy of VCN-01 with topoisomerase 1 inhibitors, an important class of chemotherapeutic agents used in a number of different cancers. We look forward to identifying opportunities to evaluate the combination of VCN-01 with additional first-line pancreatic cancer chemotherapy regimens (FOLFIRINOX or NALIRIFOX) that incorporate the topoisomerase 1 inhibitor irinotecan. Building on this momentum, we are well positioned to achieve several important milestones that will continue to drive forward our clinical development program.”
Recent Program Highlights and Anticipated Milestones:
VCN-01:
- Pancreatic Ductal Adenocarcinoma (PDAC):
- 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. The trial is expected to enroll 92 evaluable patients and is expected to complete enrollment in the third quarter of 2024.
- The ongoing Phase 2b trial continues to enroll patients across seven sites in the U.S. and ten sites in Spain. No safety concerns were raised based on the evaluation of data presented at the IDMC meeting. Intravenous VCN-01 has been well tolerated and demonstrated a safety profile consistent with prior clinical trials. Importantly, no additional toxicities were observed in patients receiving a second dose of VCN-01.
- Presented preclinical data demonstrating enhanced anti-tumor effects in human pancreatic cancer xenograft-bearing mice treated with lead product candidate VCN-01 and liposomal irinotecan. These data support the potential synergy of VCN-01 and additional first-line pancreatic cancer chemotherapy regimens and were presented at the American Society for Cell and Gene Therapy (ASGCT) 27th Annual Meeting in Baltimore from May 7-11, 2024.
- 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. The trial is expected to enroll 92 evaluable patients and is expected to complete enrollment in the third quarter of 2024.
- Retinoblastoma:
- The investigator sponsored Phase 1 trial evaluating the safety and activity of intravitreal VCN-01 in pediatric patients with refractory retinoblastoma completed patient treatment and the trial results were determined to be positive by the study Monitoring Committee.
- In the Phase 1 trial in collaboration with Sant Joan de Déu-Barcelona Children’s Hospital (SJD), patients received two intravitreal injections of VCN-01, 14 days apart, at a dose of either 2 x 109 vp/eye (n=1) or 2 x 1010 vp/eye (n=8). The safety and clinical outcomes support the therapeutic potential of VCN-01 in retinoblastoma and emphasize VCN-01’s potential for use in diverse cancer indications. Results will help inform the planned Phase 2 trial design.
- The investigator sponsored Phase 1 trial evaluating the safety and activity of intravitreal VCN-01 in pediatric patients with refractory retinoblastoma completed patient treatment and the trial results were determined to be positive by the study Monitoring Committee.
- Additional Updates:
- The trial design for VIRAGE will be discussed at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, being held in Chicago, IL, from May 31-June 4.
- Based on the strength of the science and its relevance, VIRAGE has been accepted for presentation as a trial-in-progress poster (abstract: TPS4210).
- The trial design for VIRAGE will be discussed at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, being held in Chicago, IL, from May 31-June 4.
SYN-004 (ribaxamase):
- 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 has completed enrollment into the second cohort and a data readout are expected in the third quarter of 2024. If the Data Safety and Monitoring Committee recommends continuation of the trial , enrollment into the third cohort could commence in the second half of 2024.
Business Updates
- Theriva is actively pursuing licensing discussions for our SYN-020 intestinal alkaline phosphatase asset.

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.
