Theriva™ Biologics Announces First Patient Dosed in VIRAGE2 Phase 2a Clinical Trial to Evaluate More Frequent Dosing of VCN-01 (zabilugene almadenorepvec) in First-Line Patients with Metastatic Pancreatic Ductal Adenocarcinoma

On August 6, 2026 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, reported the dosing of the first patient in the VIRAGE2 Phase 2a clinical trial, a small proof-of-concept study evaluating more frequent repeated dosing of VCN-01 (zabilugene almadenorepvec) in first-line metastatic PDAC patients treated with standard-of-care gemcitabine/nab-paclitaxel chemotherapy (SoC; see About VIRAGE2 below). Enrollment into the VIRAGE2 trial is expected to be completed in H2 2026 and initial pharmacodynamic and safety/tolerability data are anticipated by Q3 2027. Results from this trial will inform the VCN-01 dosing regimen for potential evaluation in a future pivotal Phase 3 clinical trial.

The VIRAGE2 clinical trial is based on observations from the VIRAGE Phase 2b clinical trial in metastatic PDAC patients where patients administered 2 doses of VCN-01 in combination with gemcitabine/nab-paclitaxel SoC chemotherapy exhibited improved overall survival, progression-free survival, and duration of response compared to patients treated with SoC chemotherapy alone. As previously reported, both EMA scientific advice and FDA meeting feedback recognized the improved survival in the group treated with 2 doses of VCN-01, and raised the possibility of more frequent, repeated dosing of VCN-01 in combination with SoC chemotherapy to potentially improve clinical outcomes.

"The first patient dosed in VIRAGE2 marks an important clinical development milestone as the evaluation of more frequent, repeated dosing is a critical step in the advancement of VCN-01 towards a potential pivotal Phase 3 clinical trial in metastatic PDAC patients," said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. "Our current clinical data indicate that repeated administration of VCN-01 to metastatic PDAC patients may significantly increase its tumor stroma-degrading effects and further enhance the antitumor immune response. A positive outcome from the VIRAGE2 trial will enable us to refine the design and dosing regimen of our proposed pivotal Phase 3 clinical trial in metastatic PDAC patients treated with SoC chemotherapy. Since the tumor stroma is a challenge for multiple classes of cancer therapies, a repeated VCN-01 dosing regimen may also improve outcomes when combined with other interventions such as immunotherapies, antibody-drug conjugates, KRAS inhibitors, and emerging targeted cancer treatments."

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 VIRAGE2

VIRAGE2 is a Phase 2a, single-arm, open-label, clinical trial in 6 evaluable patients with histologically confirmed, newly diagnosed metastatic PDAC enrolled at a single site in Spain. Patients are intended to receive at least three "macrocycles" of VCN-01 (zabilugene almadenorepvec) and gemcitabine/nab-paclitaxel standard-of-care (SoC) chemotherapy, followed by SoC gemcitabine/nab-paclitaxel cycles until disease progression. In each VCN-01 macrocycle, intravenous VCN-01 is administered on day 1 followed by gemcitabine/nab-paclitaxel SoC chemotherapy on days 8, 15, 22, 36, 43, and 50. Macrocycles are repeated on days 57 and 113. The primary objective of the VIRAGE2 trial is to evaluate whether administration of at least 3 doses of VCN-01, with approximately 2 months between doses, is well tolerated by patients without adversely impacting VCN-01 pharmacodynamics. Primary endpoints for the trial are the adverse event profile and levels of VCN-01 viral genomes in blood. Secondary endpoints include objective response rate, duration of response, progression free survival, overall survival, and circulating levels of anti-VCN-01 neutralizing antibodies. Exploratory endpoints include estimates of potential VCN-01 shedding by measuring VCN-01 viral genomes in sputum and stool. The study is designed with 80% power to detect a difference in VCN-01 viral genome levels between the second and first VCN-01 doses with a 2-sided alpha of 0.05. The study is not formally powered for evaluation of clinical efficacy endpoints and is intended to support evaluation of the potential efficacy of the more frequent repeated dosing regimen in subsequent clinical trials (EUCT: 2026-525566-21-00; NCT07701486).

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. With the first patient dosed in VIRAGE2, VCN-01 has been administered to 143 patients in Company- and investigator-sponsored clinical trials in 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). VCN-01 has also been made available for compassionate use in retinoblastoma patients, and 2 patients have been treated in this program. More information on VCN-01 clinical trials is available at Clinicaltrials.gov.

CancerVax Achieves Major Milestone in Activating Human Killer T-Cells Against Cancer

On August 6, 2026 CancerVax, Inc., the developer of a breakthrough universal cancer treatment platform that "tricks" the body’s immune system into fighting cancer, reported that it has successfully activated human antiviral memory CD8+ T-cells. Before T-cells can kill cancer cells, they must be first activated. The latest studies validated this important part of the platform.

The CancerVax platform is designed to harness the body’s existing immunity to detect, mark, and kill cancer cells with precision. At the core of the platform is a Smart mRNA that selectively activates in cancer cells. When activated, this Smart mRNA instructs cancer cells to produce proteins associated with viruses that are highly prevalent in the human population. This effectively disguises cancer cells as familiar viral infections and "tricks" the immune system into recognizing and killing them.

On July 14, 2026, the Company announced that it developed a novel Polyepitope Smart mRNA that can disguise cancer as multiple viral infections. This takes a shot gun approach to immune activation and was confirmed through computational analysis that it can activate pre-existing viral immunity in 99% of the world population. This Polyepitope Smart mRNA was encapsulated into the Company’s novel cell-targeting lipid nanoparticles ("LNP") and tested against a known liver cancer cell line along with human Peripheral Blood Mononuclear Cells ("PBMC").

PBMCs are white blood cells primarily comprising lymphocytes (T-cells, B-cells, and Natural Killer cells) and monocytes. A specific type of T-cells, memory CD8+ Killer T-cells, are created by the body after vaccination or natural infection to protect against reinfection. These T-cells circulate in the body from months to years after vaccination or infection. In the case of measles, memory T-cells are expected to persist for decades or even for life. The Polyepitope Smart mRNA was specifically designed to activate Killer CD8+ T-cells against common diseases such as measles, influenza, and more.

The study used an ELISpot assay, which counts individual T-cells releasing interferon-gamma, the signal a Killer T-cell sends when it recognizes its target. Human PBMCs were introduced in vitro to liver cancer cells treated with the full CancerVax therapeutic nanoparticles. The data below shows that CD8+ Killer T-cells were strongly activated in a statistically significant manner.

Dr. Adam Grant, Principal Scientist of CancerVax, commented, "This is a watershed moment for CancerVax and our novel approach to cancer immunotherapy. I’ll never forget seeing this data for the first time. These are human immune cells from real donors, not a mouse model, and they woke up to signals emanating from liver cancer cells that had been disguised to look like common diseases and are ready to attack. We took the experiment through multiple steps to make sure the results were what we hypothesized. We stripped out the CD4 T-cells and the response held. We stripped out the CD8+ T-cells and it didn’t show activation. That tells us exactly which cells were doing the work. Our next experiments are designed to test how effectively these activated memory CD8+ T-cells kill cancer cells."

"This study is an important validation of our platform’s mechanism," said Dr. George Katibah, Chief Scientific Officer of CancerVax. "By showing that our Polyepitope Smart mRNA can cause cancer cells to display familiar viral targets and activate pre-existing human antiviral CD8+ T-cells, we have demonstrated a key biological step in our strategy to redirect immune memory against cancer. Without knowing which specific immunity that the donor PBMCs have, our Polyepitope Smart mRNA made the cancer cells look like many diseases. All we need is one or more matches. These in-vitro findings confirmed that we had a strong epitope hit and support advancing the program into tumor-killing and additional preclinical studies."

"Our FHD-909 trial in collaboration with Lilly continues to advance through dose escalation, with an initial focus on SMARCA4-mutant NSCLC, a setting where effective treatment options remain limited and outcomes poor," said Adrian Gottschalk, President and Chief Executive Officer of Foghorn Therapeutics.

Mr. Gottschalk continued, "We are excited to advance our wholly-owned pipeline toward the clinic. Beyond oncology, we are now extending the reach of our platform with an undisclosed program in immunology and inflammation. We are targeting an IND in 2027 for this asset, underscoring the breadth of our platform and demonstrating its potential across multiple therapeutic areas. In oncology, our Selective EP300 degrader program in multiple myeloma has shown improved safety and efficacy versus clinical benchmarks, while our Selective CBP degrader, FHT-171, has demonstrated strong anti-tumor activity and tolerability in heavily pretreated ER+ breast cancer models. Together, these programs reflect the significant opportunity we see to expand our pipeline and create value across multiple therapeutic areas."

Program Overview and Upcoming Milestones

FHD-909 (LY4050784). FHD-909 is a first-in-class oral SMARCA2 selective inhibitor that has demonstrated in preclinical studies to have high selectivity over its closely-related paralog SMARCA4, two proteins that are the catalytic engines across all forms of the BAF complex. Selectively blocking SMARCA2 activity is a promising synthetic lethal strategy intended to induce tumor death while sparing healthy cells. SMARCA4 is mutated in up to 10% of NSCLC and implicated in a significant number of solid tumors. Across lines of therapy, significant unmet needs remain for patients with SMARCA4 (BRG1)-mutant cancers with both poor response rates and short progression-free survival.

Phase 1 trial on track. Enrollment in the first-in-human Phase 1 multi-center trial of FHD-909 is progressing well. The trial in patients with NSCLC as the primary target population is on track, following the dosing of the first patient in October 2024.

Robust and durable preclinical data for FHD-909 plus anti-PD-1 antibody. Preclinical data have demonstrated complete tumor regression in syngeneic efficacy models of FHD-909 in combination with an anti-PD-1 antibody, with no tumor regrowth observed after dosing was halted. An immune memory effect was further supported by tumor rejection upon rechallenge in treated animals.
Pending successful Phase 1 dose escalation results, Foghorn and Lilly anticipate evaluating FHD-909 in combination studies in NSCLC with pembrolizumab.

Ongoing strategic collaboration with Lilly. Foghorn is collaborating with Lilly to develop novel oncology medicines, including a 50/50 U.S. co-development and co-commercialization agreement for its selective SMARCA2 oncology program that includes both a selective inhibitor and a selective degrader, as well as an additional undisclosed oncology target. The collaboration, the research term of which will expire in December 2026, also includes three discovery programs from Foghorn’s proprietary Gene Traffic Control platform.

I&I Novel Oral Small Molecule. Foghorn is advancing a novel oral small molecule in immunology and inflammation (I&I).

IND targeted in 2027.

Selective EP300 degrader program. These degraders are being developed for the treatment of hematological malignancies and prostate cancer. Attempts to selectively drug EP300 have been challenging due to the high level of similarity between EP300 and CBP, while dual inhibition of CBP/EP300 has been associated with dose limiting toxicities. EP300 lineage dependencies are established in multiple myeloma (MM) and diffuse large b-cell lymphoma (DLBCL).

EP300 degrader program outperforms clinical benchmark. Preclinical data highlight the therapeutic potential in multiple myeloma, including superior anti-tumor activity with complete responses, compared to clinical benchmark dual CBP/EP300 inhibitor inobrodib, superior safety by body weight loss and platelet counts over dual degradation, and tumor regression in a multiple myeloma xenograft model of acquired pomalidomide resistance.
IND targeted in 2027, with a focus in MM and DLBCL.

Selective CBP degrader program. These degraders selectively target CBP, an acetyltransferase closely related to EP300. CBP lineage dependencies are established in several cancers, including breast cancer, and there is also a synthetic relationship in EP300-mutated cancers, which include endometrial, cervical, ovarian, bladder, and colorectal cancer. Attempts to selectively drug CBP have been challenging due to the high level of similarity between the two proteins, while dual inhibition of CBP/EP300 has been associated with dose-limiting toxicities.

CBPd-171 shows strong therapeutic potential in ER+ breast cancer. Preclinical data for our lead Selective CBP degrader, CBPd-171, highlighted strong anti-tumor activity as a monotherapy in PDX models of heavily pretreated ER+ breast cancer, favorable preclinical in vivo tolerability profile, and high selectivity and potent CBP degradation with clear on-target transcriptional effects. We have developed a long-acting injectable (LAI) formulation for weekly subcutaneous administration to support convenient and patient-friendly dosing.
The CBPd-171 timeline has been delayed due to an unexpected operational issue at a third-party contract research organization supporting the in vivo animal models. The Company will provide updated guidance once available.

Selective ARID1B degrader program. These degraders selectively target and degrade ARID1B and are being positioned as synthetic lethal opportunities for ARID1A-mutated cancers. ARID1A is the most mutated subunit in the BAF complex and amongst the most mutated proteins in cancer. These mutations lead to a dependency on ARID1B in several types of cancer, including endometrial, gastric, bladder and NSCLC. Attempts to selectively drug ARID1B have been challenging because of the high degree of similarity between ARID1A and ARID1B and the fact that ARID1B has no enzymatic activity to target. ARID1B is a major synthetic lethal target implicated in up to 5% of all solid tumors.

First-in-class Selective ARID1B degrader program. Robust degradation with potential for oral bioavailability demonstrated preclinically across our cereblon-based Selective ARID1B degraders. Foghorn is developing cereblon-based bifunctional degraders achieving selective degradation of ARID1B and modulation of downstream target genes consistent with ARID1B pathway disruption.

Platform. Foghorn continues to advance its chromatin biology and degrader platform with investments in molecular glues, RIPTACs and induced proximity.

Second Quarter 2026 Financial Highlights

Collaboration Revenue. Collaboration revenue was $16.1 million for the three months ended June 30, 2026, compared to $7.6 million for the three months ended June 30, 2025. The $8.5 million increase was driven by a $14.2 million cumulative catch-up adjustment to reflect updated future costs primarily due to the scheduled expiration of the research term in December 2026 partially offset by the timing of work performed under the Lilly Collaboration Agreement.

Research and Development Expenses. Research and development expenses were $18.5 million for the three months ended June 30, 2026, compared to $21.8 million for the three months ended June 30, 2025. The $3.3 million decrease is attributed to a decrease in Lilly-partnered program costs, decreases in facilities and IT-related expenses, a decrease in FHD-286 costs, and decreases in personnel-related costs partially offset by an increase in early development and other external costs.

General and Administrative Expenses. General and administrative expenses were $6.4 million for the three months ended June 30, 2026, compared to $6.9 million for the three months ended June 30, 2025. This $0.5 million decrease was primarily due to lower facilities and IT-related expenses.

Net Loss. Net loss was $7.2 million for the three months ended June 30, 2026, compared to a net loss of $17.9 million for the three months ended June 30, 2025.

Cash, Cash Equivalents, and Marketable Securities. As of June 30, 2026, the Company had $167.6 million in cash, cash equivalents, and marketable securities, providing cash runway into the first half of 2028.

About FHD-909

FHD-909 (LY4050784) is a potent, first-in-class, allosteric, and orally available small molecule that selectively inhibits the ATPase activity of SMARCA2 (BRM) over its closely related paralog SMARCA4 (BRG1), two proteins that are the catalytic engines across all forms of the BAF complex, one of the key regulators of the chromatin regulatory system. In preclinical studies, tumors with mutations in SMARCA4 rely on SMARCA2 for their survival. FHD-909 has shown significant anti-tumor activity across multiple SMARCA4-mutant lung tumor models.

"We are increasingly encouraged by the strength and consistency of the tovecimig data as we deepen our analyses ahead of engaging FDA later this month, and we are pleased the full dataset has been selected for an oral presentation at ESMO (Free ESMO Whitepaper) in October. This enthusiasm is echoed in feedback we’ve received from leading BTC clinicians, which reinforces our belief that tovecimig will be an important treatment option for so many patients with BTC. In the coming weeks, we will be focused on engaging constructively with the FDA and incorporating any feedback as we advance towards a potential BLA filing," said Thomas Schuetz, MD, PhD, Chief Executive Officer and Vice Chairman of the Board of Directors.

"Building on our progress with tovecimig, we continued to advance our broader clinical pipeline this quarter. CTX-8371, our novel PD-1 x PD-L1 checkpoint inhibitor, continues to generate strong and durable clinical activity, some of which was presented at ASCO (Free ASCO Whitepaper), and we are well underway with cohort expansions. We also continue to enroll patients in the Phase 1 study of CTX-10726, our differentiated PD-1 x VEGF-A bispecific antibody. We look forward to sharing a series of meaningful updates in the remainder of 2026, including FDA feedback shortly, that demonstrate our continued execution across the portfolio and our ability to translate novel science into differentiated clinical products."

Pipeline Updates:

Tovecimig (DLL4 x VEGF-A bispecific antibody)

In April 2026, the Company announced positive data from its Phase 2/3 study of tovecimig, which it plans to include in a BLA submission later this year. The company expects to receive feedback from the FDA on these data in Q3 2026.
In the final data analysis, the overall response rate (ORR), the primary endpoint in the study, improved to 18.0% (20/111 patients) in the tovecimig combination arm from a previously reported 17.1%. One patient initially characterized as "Non-CR / Non-PD" due to target lesion characteristics was ultimately adjudicated by blinded independent central review (BICR) to be a partial response. With this change, the p-value improved to 0.0228 compared to paclitaxel alone (ORR of 5.3% in the paclitaxel arm).
The investigator sponsored trial (IST) of tovecimig in combination with the current first-line, standard-of-care regimen of gemcitabine, cisplatin, and durvalumab in patients with BTC (NCT06548412) is ongoing with expansion to additional sites expected.
Additional ISTs of tovecimig have been initiated, including a study of tovecimig plus FOLFIRI in patients with colorectal cancer in the second line setting (NCT07662031); and a novel-novel combination study of tovecimig plus CTX-471 in patients with glioblastoma in the second line setting (NCT07392957). The Company is evaluating additional studies for tovecimig in other indications, including both ISTs and Company-sponsored studies.

CTX-8371 (PD-1 x PD-L1 bispecific antibody)

Cohort expansions for CTX-8371 are actively enrolling patients with triple-negative breast cancer (n=28), non-small cell lung cancer (n=28), and Hodgkin lymphoma (n=12) in the post-checkpoint inhibitor setting. These indications were selected based on the deep and durable responses observed in these indications in the dose escalation portion of the study. Half of the patients with each tumor type will be dosed at 3.0 mg/kg and half will be dosed at 10.0 mg/kg.
Phase 1 data from the dose-escalation portion of the study was presented at ASCO (Free ASCO Whitepaper) 2026. Additional data from the cohort expansions are expected in Q4 2026.

CTX-10726 (PD-1 x VEGF-A bispecific antibody)

The first patients have been dosed in the Phase 1 study, and the study is actively enrolling, with initial clinical data expected in Q4 2026.
The Phase 1 multiple ascending dose-escalation study will include four doses (0.3, 1.0, 3.0, and 10.0 mg/kg) in a 3+3 dose-escalation design. The multi-center study will enroll patients with a prioritized set of solid tumor indications, including patients with locally advanced, unresectable or metastatic renal cell carcinoma, gastroesophageal cancer, hepatocellular carcinoma, and endometrial cancer, in whom standard of care therapies have failed.
CTX-10726 is a tetravalent PD-1 x VEGF-A bispecific antibody discovered and engineered by the Company. CTX-10726 exhibits more potent PD-1 blockade compared with data reported for other drugs in the class.

CTX-471 (CD137 or 4-1BB agonist antibody)

The Phase 2 trial of CTX-471 in patients with tumors expressing NCAM (CD56) will be initiated in Q3 2026.

Financial Results

Net loss for the quarter ended June 30, 2026, was $25.2 million or $0.13 per common share, compared to $19.9 million or $0.14 per common share for the same period in 2025. Net loss for the six months ended June 30, 2026, was $43.5 million or $0.23 per common share, compared to $36.5 million or $0.26 per common share for the same period in 2025.

Research and Development (R&D) Expenses

R&D expenses were $19.6 million for the quarter ended June 30, 2026, as compared to $16.4 million for the same period in 2025, an increase of $3.2 million or 19%. This was primarily driven by an increase of $2.6 million of expenses related to tovecimig. R&D expenses were $33.0 million for the six months ended June 30, 2026, as compared to $29.5 million for the same period in 2025, an increase of $3.5 million or 12%. This was primarily driven by an increase of $2.5M of stock compensation expense and $1.3M of manufacturing expense.

General and Administrative (G&A) Expenses

G&A expenses were $7.4 million for the quarter ended June 30, 2026, as compared to $4.7 million for the same period in 2025, an increase of $2.7 million or 59%. This was primarily driven by an increase of $1.4 million of pre-commercialization expenses and $0.8 million of higher stock compensation expense. G&A expenses were $14.3 million for the six months ended June 30, 2026, as compared to $9.6 million for the same period in 2025, an increase of $4.7 million or 50%.
