Theriva Biologics Announces First Patient Dosed in VIRAGE, a Phase 2b Trial of Systemically Administered VCN-01 in Combination with Chemotherapy in Pancreatic Ductal Adenocarcinoma
Theriva Biologics (NYSE American: TOVX) announced the initiation of its Phase 2b trial, VIRAGE, for the treatment of newly-diagnosed metastatic pancreatic ductal adenocarcinoma (PDAC). The first patient has been dosed in Spain, with a total enrollment of 92 adults planned across the US, Spain, and Germany. The trial will evaluate the safety and efficacy of VCN-01 combined with standard chemotherapy (gemcitabine/nab-paclitaxel). Primary endpoints include overall survival and safety, with additional metrics assessing progression-free survival and immune response. This trial represents a vital step towards improving treatment for patients with high unmet needs in oncology.
- FDA and AEMPS clearance for the Phase 2b trial.
- First patient dosed in a trial addressing a significant medical need.
- Study design allows for rapid adaptation based on early data.
- None.
-Initiation of Phase 2b trial follows clearance from the US Food and Drug Administration (FDA) and Spanish Agency for Medicines and Health Products (AEMPS)-
-The first patient was dosed in Spain; trial expected to enroll 92 adults at sites across the US, Spain, and Germany-
ROCKVILLE, Md., Jan. 17, 2023 (GLOBE NEWSWIRE) -- 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 the first patient has been dosed in VIRAGE, the Phase 2b randomized, open-label, placebo-controlled, multicenter clinical trial of systemically administered VCN-01 in combination with standard-of-care (SoC) chemotherapy (gemcitabine/nab-paclitaxel) as a first line therapy for patients with newly-diagnosed metastatic pancreatic ductal adenocarcinoma (PDAC).
“The dosing of the first patient in our Phase 2b PDAC trial represents an important step in our pursuit to address unmet needs for patients with difficult-to-treat cancers,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “The incidence of PDAC continues to rise and while it continues to have one of the lowest survival rates among all cancer types, efforts to improve upon the standard of care treatment have largely stalled. In contrast, we are encouraged by the growing clinical data that underscore VCN-01’s differentiated mechanism of action, as well as the biological activity and synergistic clinical benefit observed in combination with SoC chemotherapy for patients with PDAC and other solid tumors. With regulatory clearance from the FDA and AEMPS, we look forward to the continued progress of this program and more broadly, the advancement of our novel OV platform.”
About VIRAGE
VIRAGE is a two-arm Phase 2b open-label, randomized, controlled, multicenter clinical trial in patients with histologically confirmed, newly-diagnosed metastatic PDAC. VIRAGE is expected to enroll up to 92 adult participants at up to 25 sites across the US, Spain, and Germany. In both the control and treatment arms, patients will receive gemcitabine/nab-paclitaxel standard of care chemotherapy over 28-day cycles. In the treatment arm only, patients will also receive systemically administered VCN-01 seven-days prior to the first and fourth cycles of gemcitabine/nab-paclitaxel treatment. Primary endpoints for the trial include overall survival and VCN-01 safety/tolerability. Additional endpoints include progression free survival, objective response rate, and measures of biodistribution, VCN-01 replication, and immune response. Since this is an open label trial, progress will be monitored very closely and steps to accelerate the clinical program may be implemented if supported by the emerging data. More information about the trial is available here and through the Spanish Clinical Trials Registry (EudraCT Number: 2022-000897-24).
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 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.
