NEWS -- Theriva™ Biologics Announces Results from VCN-01 Phase 1 Clinical Trial in Head and Neck Cancer Published in Clinical Cancer Research



Prolonged overall survival (OS) was observed in heavily pre-treated refractory Head & Neck Squamous Cell Carcinoma (HNSCC) patients administered IV VCN-01 prior to the immune checkpoint inhibitor durvalumab

Pharmacokinetic, tissue biopsy, radiomic and transcriptomic results all support the proposed VCN-01 stroma-degrading and immune enhancing modes-of-action and resensitization of refractory tumors to durvalumab

Increased levels of PD-L1 positive T-cells and other biomarkers were found in patients after sequential administration of VCN-01 and durvalumab, consistent with reactivation of immune responsesROCKVILLE, Md., June 11, 2026 (GLOBE NEWSWIRE) -- Theriva™ Biologics, Inc. (NYSE American: TOVX), a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need, today announced that clinical and translational results from VCN-01’s Phase 1 clinical trial in Head & Neck Squamous Cell Carcinoma (HNSCC) were recently published on-line first in the journal Clinical Cancer Research. The article, titled “Phase I trial of intravenous VCN-01 oncolytic adenovirus and durvalumab in patients with head and neck metastatic squamous cell carcinoma refractory to immunotherapy”, can be read here.

“We are very excited to see Clinical Cancer Research share the VCN-01 results in immunotherapy-refractory metastatic HNSCC patients with the broad oncology community,” said Ricard Mesia (Catalan Institute of Oncology, ICO), expert on HNSCC and coordinating investigator in this study. “The trial demonstrates the ability of VCN-01 to resensitize tumors from these heavily pretreated patients to the immune checkpoint inhibitor durvalumab. Pharmacokinetic, tissue biopsy, radiomic and transcriptomic results from the study all support the VCN-01 stroma-degrading mode-of-action, being investigated to enhance tumor penetration by VCN-01 and coadministered therapies and enable/enhance an anti-tumor immune response. There are very few treatment options available to immunotherapy-refractory metastatic HNSCC patients, and the clinically impactful findings from this report encourage further clinical development of VCN-01 with immune checkpoint inhibitors or other immune modulating anticancer therapies.”

Data summary – VCN-01 Phase 1 clinical trial (NCT03799744) in metastatic, immunotherapy-refractory Head & Neck Squamous Cell Carcinoma (HNSCC)

The trial enrolled 20 adult patients with refractory or metastatic HNSCC, whose disease progressed despite previous therapies, including anti-PD-(L)1 immune checkpoint inhibitors. Six patients were enrolled into the concomitant Arm I LD of the study and were administered IV low dose VCN-01 (3.3E12 virus particles; LD) four hours prior to a fixed IV dose of durvalumab (1500 mg/q4w). Eight patients were enrolled into the sequential Arm II LD of the study, receiving low dose IV VCN-01 14 days prior to IV durvalumab administration. An additional six patients were entered into Arm II HD, receiving high dose IV VCN-01 (1.0E13 virus particles; HD) 14 days prior to IV durvalumab administration.

Median progression-free survival (PFS) was 1.6 months in Arm I LD, 3.7 months in Arm II LD, and 2.1 months in Arm II HD.

Median overall survival (OS) was 10.3 months in Arm I LD, 15.5 months in Arm II LD, and 17.3 months in Arm II HD.

Circulating levels of the stroma-degrading hyaluronidase enzyme PH20 (expressed during selective VCN-01 intratumoral replication) increased significantly after VCN-01 administration in all tested patients, peaking on day 3-8 for most patients and detectable until day 28 in 11 of 12 patients.

Similarly, VCN-01 viral genome levels detected in patient blood exhibited an initial peak immediately following administration and a secondary peak on day 3-8, consistent with continued viral replication in tumors followed by a return of virus to circulation.

Upregulation of CD8 and IDO was observed in tumor biopsy samples, consistent with increased tumor infiltration by activated cytotoxic T cells – historically associated with increased HNSCC patient survival. Diminished levels of FoxP3, CD25, and CTLA4 were also observed, consistent with a reduction in tumor Tregs and inhibition of tumor immunosuppression.

Tumor biopsies revealed upregulation of PD-1 and PD-L1 in most patients following VCN-01 administration that correlated with patient survival, suggesting that immune system activity and heightened PD-L1 expression in tumors contributed to the improved outcomes from VCN-01 and durvalumab combination.About Theriva™ Biologics, Inc.

Theriva Biologics (TOVX) Stock Soars 63% on Promising Pancreatic Cancer Trial Results

April 20, 2026

• Shares of Theriva Biologics (TOVX) surged 63% following the release of encouraging VIRAGE Phase 2b clinical trial results

• Combination therapy using VCN-01 with conventional chemotherapy demonstrated enhanced overall survival compared to chemotherapy alone in metastatic pancreatic cancer

• Positive outcomes were observed across various patient subgroups, notably those presenting with liver metastases

• The biotechnology firm has secured regulatory alignment with both FDA and EMA for its upcoming Phase 3 pivotal study

• With a modest market capitalization of $11.7M and share price at $0.25, TOVX reflects the inherent risks of early-stage biotechnology investments

During the American Association for Cancer Research (AACR) Annual Meeting held in San Diego on April 20, 2026, Theriva Biologics unveiled updated findings from its VIRAGE Phase 2b clinical study.

Dr. Manuel Hidalgo from NYU Langone Health’s Perlmutter Cancer Center presented the data during a poster session.

The clinical investigation evaluated VCN-01 administered alongside gemcitabine and nab-paclitaxel versus standard chemotherapy alone in individuals recently diagnosed with metastatic pancreatic cancer.

Findings revealed that participants who received the VCN-01 combination therapy experienced superior overall survival and progression-free survival metrics compared to the control group receiving only chemotherapy.

The therapeutic responses observed in the VCN-01 treatment arm were characterized as emerging later in the treatment course, demonstrating greater magnitude, and exhibiting enhanced durability — suggesting what researchers believe represents an immune-mediated therapeutic mechanism.

The survival advantages remained relatively consistent across diverse patient populations. This notably included individuals with liver metastases, a subgroup traditionally associated with more challenging treatment outcomes.

Participants who were administered a second VCN-01 dose demonstrated potentially superior therapeutic benefits, which company officials interpret as supporting evidence for prolonged dosing strategies.

Regulatory Agencies Align on Phase 3 Study Design
Theriva Biologics announced it has successfully achieved regulatory alignment with both the U.S. Food and Drug Administration and the European Medicines Agency regarding the framework for a definitive Phase 3 clinical trial.

The planned Phase 3 investigation would assess multiple VCN-01 dosing regimens combined with gemcitabine and nab-paclitaxel in treatment-naive metastatic pancreatic cancer patients.

Additionally, the organization indicated intentions to conduct a supplementary investigation examining whether increased frequency or extended duration of VCN-01 administration could further enhance patient outcomes.

VCN-01 represents a systemically delivered oncolytic adenovirus platform. The therapeutic agent is engineered to selectively replicate within malignant cells and degrade tumor stromal architecture, theoretically enhancing penetration and efficacy of concurrently administered treatments.

To this point, the investigational therapy has been administered to 142 individuals across multiple clinical trials encompassing various malignancy types.

Market Response and Corporate Overview
TOVX shares experienced a 63% price increase following the announcement, though the organization maintains a relatively small market capitalization of merely $11.7 million with shares trading at $0.25.

This valuation underscores the considerable risks inherent in investing in clinical-stage biotechnology companies without revenue generation and facing continued capital consumption.

Wall Street Perspective
The latest analyst assessment on TOVX carries a Buy recommendation, establishing a price objective of $1.00. Analyst price targets span a range between $1 and $4.

A notable complication: Theriva recently failed to convene a Special Meeting of Stockholders due to insufficient quorum attendance. The gathering was scheduled to vote on a warrant exercise proposition. Management intends to reconvene the meeting.

Pancreatic ductal adenocarcinoma represents over 90% of all pancreatic malignancies, with approximately 50–60% of patients presenting with distant metastatic disease at initial diagnosis.

The AACR data presentation occurred on April 20 between 2:00–5:00 PM PDT at the San Diego Convention Center.

Title: Analysis of tumor and biomarker responses in the VIRAGE Trial, a randomized Phase IIb, open-label, study of nab-paclitaxel and gemcitabine with/without intravenous VCN-01 in patients with metastatic pancreatic cancer (mPDAC)

Poster #: CT162

Date and time: Monday April 20, 2026, 2:00-5:00 PM US PDT

Session: PO.CT01.05 - Phase II and Phase III Clinical Trials

Location: San Diego Convention Center, Hall B, Section 52, Board 26.“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 https://Clinicaltrials.gov.

“The acquisition of Terns builds on our growing presence in hematology with TERN-701, a potential best-in-class candidate for the treatment of certain patients with chronic myeloid leukemia,” said Robert M. Davis, chairman and chief executive officer, Merck. “This transaction further diversifies and strengthens our position in oncology as we continue to look for opportunities to broaden our portfolio into other therapeutic areas.”

Terns’ lead candidate, TERN-701, is a novel investigational oral allosteric BCR::ABL1 tyrosine kinase inhibitor (TKI) currently being evaluated in the Phase 1/2 CARDINAL trial (NCT06163430) for patients with Philadelphia chromosome-positive (Ph+), chronic phase chronic myeloid leukemia (CML) previously treated with at least one prior TKI and who experienced treatment failure, suboptimal response or treatment intolerance. In March 2024, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for TERN-701 for the treatment of CML.

“This acquisition reflects our team’s deep commitment to innovation in oncology and developing high impact medicines,” said Amy Burroughs, chief executive officer, Terns. “By working together, we will advance TERN-701, leveraging the deep expertise and significant resources at Merck, a global biopharmaceutical leader with a proven track record of delivering cancer breakthroughs for patients who need them most. I am immensely proud of the Terns team and our work towards making a difference for people living with CML. Finally, we extend our heartfelt thanks to the investigators, patients, and community advocates whose dedication and support make the development of TERN-701 possible.”

In clinical trials to date, TERN-701 has shown promising activity, with encouraging rates of major molecular response and deep molecular response observed by week 24. Importantly, this includes responses in patients with high disease burden who previously received multiple lines of therapy, including many who were treated with an allosteric TKI. The majority of treatment-emergent adverse events were reported as low grade with a low incidence of severe adverse events and discontinuations. No clinically meaningful changes in blood pressure have been observed, and rates of lipase elevation have been low.

“The first approval of a BCR::ABL1 tyrosine kinase inhibitor 25 years ago transformed the prognosis for many patients with chronic myeloid leukemia. Despite new therapeutic options, there is significant need for innovative, well-tolerated therapies with faster time to onset of molecular response leading to deeper responses and better disease control,” said Dr. Dean Y. Li, president, Merck Research Laboratories. “Based on early clinical evidence, TERN-701, a novel allosteric BCR::ABL1 inhibitor, may have the potential to provide a meaningfully differentiated option for certain patients living with CML.”

The transaction has been approved by both Merck’s and Terns’ Boards of Directors. Under the terms of the merger agreement, Merck, through a subsidiary, will acquire all of the outstanding shares of Terns. The acquisition is subject to a majority of Terns’ stockholders tendering their shares in a tender offer that will be initiated by a subsidiary of Merck. The closing of the proposed transaction will be subject to certain conditions, including the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions. The transaction is expected to be accounted for as an asset acquisition and close in the second quarter of 2026, resulting in a charge of approximately $5.8 billion, or approximately $2.35 per share, included in both second quarter and full year 2026 GAAP and non-GAAP results.

A copy of the merger agreement for the transaction will be filed with the Securities and Exchange Commission (“SEC”) and will be publicly available free of charge at the SEC’s website at www.sec.gov. Copies of the documents filed with the SEC by Merck may be obtained at no charge from Merck’s website at www.merck.com or by contacting Merck at 126 East Lincoln Avenue, P.O. Box 2000, Rahway, NJ 07065 USA, or (908) 740-4000. Copies of the documents filed with the SEC by Terns may be obtained at no charge from Terns’ website at www.ternspharma.com or by contacting Terns at 1065 East Hillsdale Blvd., Suite 100, Foster City, CA 94404 or (650) 525-5535 Ext.101.

NEWS -- Theriva™ Biologics Announces Positive End-of-Phase 2 Meeting with U.S. FDA Regarding the Design of a Phase 3 Trial of VCN-01 in Metastatic Pancreatic Ductal Adenocarcinoma



– Successful meeting with FDA enables advancement into proposed Phase 3 clinical trial of VCN-01 in combination with gemcitabine/nab-paclitaxel for the first-line treatment of metastatic PDAC –

– Combined feedback from FDA and previously from EMA enables company to finalize protocol for pivotal Phase 3 clinical trial while pursuing strategic funding opportunities –

ROCKVILLE, Md., March 23, 2026 (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 announced the outcomes of a recent Type B End-of-Phase 2 (EOP2) meeting with the U.S. Food and Drug Administration (FDA) regarding the design of a Phase 3 clinical study of lead clinical candidate VCN-01 in combination with standard-of-care chemotherapy for the treatment of metastatic pancreatic adenocarcinoma (PDAC).

The FDA provided general agreement with Theriva’s proposed design for a Phase 3 clinical trial, which closely tracks the design of the successful VIRAGE Phase 2 trial. As announced in 2025, the VIRAGE trial met its primary endpoints, with metastatic PDAC patients receiving VCN-01 with SoC chemotherapy having improved overall survival (OS), progression free survival (PFS) and Duration of Response (DoR) compared to SoC chemotherapy alone. Greater improvements in OS and PFS were observed in patients who received two doses of VCN-01, leading Theriva to plan the Phase 3 trial to include repeat dosing and an adaptive design aimed to optimize the trial’s timelines and outcomes.

Consistent with scientific advice previously received from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA), the FDA advised that a potential biologics licensing application (BLA) for VCN-01 in metastatic PDAC could be supported by Theriva’s proposed Phase 3 clinical trial (if successful) comprising a single, high-quality, randomized, double-blinded, study comparing VCN-01 plus gemcitabine/nab-paclitaxel SoC to gemcitabine/nab-paclitaxel SoC plus placebo. The FDA further agreed on the proposed dosing of VCN-01 and gemcitabine/nab-paclitaxel in repeated “macrocycles” (enabling more than 2 doses of VCN-01 to be administered in the Phase 3 trial), the proposed inclusion/exclusion criteria, the primary endpoint (overall survival), key secondary endpoints (including progression free survival), and the use of an adaptive design. The FDA also clarified statistical expectations regarding the proposed interim analyses and the quality of data required for potential sample size re-estimation or a demonstration of early efficacy.

“We are very pleased to align with the FDA on the key elements of our proposed pivotal Phase 3 trial evaluating VCN-01 plus gemcitabine/nab-paclitaxel SoC in metastatic PDAC patients,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “Data from our VIRAGE Phase 2b study demonstrated improved outcomes in PDAC patients treated with 2 doses of VCN-01 and we believe that administering multiple macrocycles of VCN-01 and gemcitabine/nab-paclitaxel that may further improve patient outcomes. The combined feedback from the FDA and the EMA now enables us to finalize the protocol for a pivotal Phase 3 clinical trial and pursue development funding and/or partnerships, which, if successful, may deliver a novel and effective treatment option for patients with this difficult to treat solid tumor cancer.”

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 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 Company- and investigator-sponsored clinical trials of different cancers, including PDAC (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 https://Clinicaltrials.gov.

"We are very encouraged by the scientific advice we received from the EMA regarding our proposed pivotal Phase 3 trial of VCN-01 plus gemcitabine/nab-paclitaxel SoC in metastatic PDAC patients,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “We are particularly pleased with EMA agreement on the VCN-01 macrocycle dosing regimen. As we demonstrated in the VIRAGE Phase 2b study, patients who received 2 doses of VCN-01 had improved survival outcomes, therefore we anticipate 3 or more doses of VCN-01 should provide an even greater survival benefit. We plan to complete an End-of-Phase 2 meeting with the FDA in the first half of 2026 and finalize the protocol for a pivotal multinational Phase 3 trial, intended to deliver an innovative therapeutic option for patients diagnosed with this rapidy fatal disease. We recognize that regulatory clarity on development pathways is essential for the on-going partnering efforts for our VCN-01 clinical programs. In addition to regulatory advice on the proposed PDAC Phase 3 clinical trial, interactions with EMA and FDA are planned in 2026 to seek advice on a potential Phase 2/3 trial for VCN-01 in retinoblastoma, a challenging childhood cancer for which VCN-01 has been granted Rare Pediatric Disease designation

Potential buyout candidate here too!! Big fish out there can target tovx near future!!

We are very pleased to have completed the licensing of our versatile Phase 2-ready asset SYN-020 to Rasayana Therapeutics, executing on our plan to derive value from our GI portfolio while we remain focused on the advancement of our oncology pipeline,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “We continue to advance our lead oncolytic virus candidate VCN-01 towards pivotal clinical development in multiple indications of high unmet need.
