"Our third quarter demonstrated exceptional execution across our clinical portfolio," said Marianne De Backer, Chief Executive Officer, Vir Biotechnology. "We completed ECLIPSE 1 enrollment approximately two months ahead of schedule and continue to see strong momentum across ECLIPSE 2 and 3, positioning us well for our hepatitis delta regulatory submissions. We are excited to provide guidance for a comprehensive VIR-5500 data update in the first quarter of 2026, and we recently expanded into first-line prostate cancer with our ARPI combination study. These achievements reflect our team’s commitment to delivering transformative therapies to patients with significant unmet medical needs."

Pipeline Programs

Chronic Hepatitis Delta (CHD)

The ECLIPSE 1 Phase 3 trial has completed enrollment approximately two months ahead of the Company’s internal projections. Primary completion is expected in the fourth quarter of 2026, with topline data expected in the first quarter of 2027. ECLIPSE 1 evaluates the combination of tobevibart and elebsiran compared to deferred treatment in regions such as the U.S. where bulevirtide is not available or in other regions where its use is limited.
The ECLIPSE 2 Phase 3 trial continues enrolling well, and topline data are expected in the first quarter of 2027. ECLIPSE 2 evaluates the switch to the combination of tobevibart and elebsiran in participants who have not achieved undetectable hepatitis delta virus RNA with bulevirtide treatment.
The ECLIPSE 3 Phase 2b trial is progressing ahead of schedule with strong enrollment momentum, and topline data are expected in the first quarter of 2027. ECLIPSE 3 evaluates the combination of tobevibart and elebsiran compared to bulevirtide monotherapy in bulevirtide treatment-naïve participants.
Following positive data presented at American Association for the Study of Liver Diseases (AASLD) The Liver Meeting 2024, the Company will present Week 48 endpoint results from its SOLSTICE Phase 2 clinical study, in patients with CHD at AASLD The Liver Meeting 2025. The oral presentation will take place on Sunday, November 9.
Solid Tumors

VIR-5500, a PRO-XTEN dual-masked T-cell engager (TCE) targeting prostate-specific membrane antigen (PSMA), continues to advance through Phase 1 dose escalation as a monotherapy in heavily pre-treated patients with metastatic castration-resistant prostate cancer (mCRPC) and has demonstrated promising early anti-tumor activity and a favorable safety profile.
First patient dosed in Phase 1 clinical study of VIR-5500 in combination with ARPIs in first-line mCRPC.
The Company plans to share a comprehensive VIR-5500 data update in late-line patients in the first quarter of 2026.
VIR-5818, a PRO-XTEN dual-masked TCE targeting HER2, continues in a Phase 1 dose escalation study in combination with pembrolizumab.
VIR-5818 is the only dual-masked HER2-targeting TCE in clinical development and is being evaluated in multiple tumor types, including metastatic colorectal cancer (CRC).
VIR-5525, a PRO-XTEN dual-masked TCE targeting EGFR, continues enrollment in the Phase 1 trial as expected.
VIR-5525 leverages learnings from VIR-5500 and VIR-5818 and is being evaluated in a variety of EGFR-expressing solid tumors in areas of high unmet need, such as non-small cell lung cancer, CRC, head and neck squamous cell carcinoma, and cutaneous squamous cell carcinoma.
Preclinical Pipeline Candidates

Harnessing the Company’s deep immune system expertise combined with its discovery and engineering platform and proprietary dAIsY (data AI structure and antibody) AI engine, the Company continues to advance multiple undisclosed PRO-XTEN masked TCEs directed toward validated targets with potential application across a number of solid tumors.
Third Quarter 2025 Financial Results

Cash, Cash Equivalents and Investments: As of September 30, 2025, the Company had $810.7 million in cash, cash equivalents and investments, representing a decrease of approximately $81.4 million during the third quarter of 2025.

Revenues: Total revenues for the third quarter of 2025 were $0.2 million compared to $2.4 million for the same period in 2024.

Cost of Revenue: The change in cost of revenue for the third quarter of 2025 compared to the same period in 2024 was nominal.

Research and Development Expenses (R&D): R&D expenses for the third quarter of 2025 were $151.5 million, which included $5.5 million of non-cash stock-based compensation expense, and $75.0 million of milestone payments paid from restricted cash, compared to $195.2 million for the same period in 2024, which included $8.9 million of non-cash stock-based compensation expense and $102.8 million of license expenses. The decrease was primarily driven by lower license expenses and cost savings from previously announced restructuring initiatives, partially offset by higher clinical expenses from our ECLIPSE registrational program for CHD and progression of our oncology programs.

The $75.0 million milestone payment to former shareholders of Amunix Pharmaceuticals, Inc. was triggered by VIR-5525 achieving first-in-human dosing and was paid from restricted cash held in escrow since the execution of the license agreement with Sanofi S.A. (Sanofi), therefore having no impact on our reported cash position or runway. The prior year license expenses were primarily due to the recognition of the $102.8 million Sanofi upfront payment as in-process research and development expense in the third quarter of 2024.

Selling, General and Administrative Expenses (SG&A): SG&A expenses for the third quarter of 2025 were $22.2 million, which included $5.8 million of non-cash stock-based compensation expense, compared to $25.7 million for the same period in 2024, which included $7.8 million of non-cash stock-based compensation expense. The decrease was largely due to efficiencies and cost savings from previously announced restructuring initiatives.

Restructuring, Long-Lived Assets Impairment and Related Charges, Net: The Company incurred no restructuring, long-lived assets impairment and related charges, net for the third quarter of 2025 compared to $12.7 million for the same period in 2024. The decrease was due to the fact that our restructuring initiatives implemented in prior years were substantially completed by the end of 2024.

Other Income: Other income for the third quarter of 2025 was $10.5 million compared to $17.8 million for the same period in 2024. The decrease was primarily driven by lower interest income.

Provision for Income Taxes: The provision for income taxes for the third quarter of 2025 was nominal.

Net Loss: Net loss for the third quarter of 2025 was $163.1 million, or $1.17 per share, basic and diluted, compared to a net loss of $213.7 million, or $1.56 per share, basic and diluted for the same period in 2024.

2025 Financial Guidance

Based on current operating plans, the Company expects its cash, cash equivalents and investments to fund operations into mid-2027.

Conference Call

Vir Biotechnology will host a conference call to discuss the third quarter results at 1:30 p.m. PT / 4:30 p.m. ET today. A live webcast will be available on View Source and will be archived for 30 days.

The study was published in a new Brief Report in Vaccines on November 2, 2025. The peer-reviewed Brief Report details the development of a second-generation, clinical-grade DC construct that achieved complete regression of both primary and metastatic pancreatic tumors in preclinical humanized models. Pancreatic cancer is one of the deadliest cancers, often diagnosed late and resistant to conventional treatments. Lunai’s therapy uses engineered dendritic cells — specialized immune cells created from stem cells — that are genetically enhanced to activate the body’s immune system against cancer. This publication details a second-generation, clinical-compliant version of this platform, with the provided evidence critical in advancing ongoing partnering conversations for the therapy.

This new publication builds on Lunai’s earlier study (Vaccines 2025 Jul 12;13(7):749; doi:10.3390/vaccines13070749), which first demonstrated potent anti-tumor activity of CD34+ hematopoietic stem cell (HSC)-derived DCs engineered to overexpress CD40L, CD93, and CXCL13 in humanized mouse models of pancreatic cancer. While the initial study utilized a research-grade lentiviral vector, the latest report describes an optimized, clinically compliant construct that preserves equivalent efficacy while improving design and manufacturing attributes to support future clinical translation.

The second-generation construct features a strong mammalian promoter and enhanced genetic elements to drive expression of key immune-modulating molecules. In preclinical humanized models, Lunai’s next-generation DC therapy triggered robust activation of cytotoxic T cells and NK cells and led to complete regression of both primary and metastatic pancreatic tumors. These findings mirrored the outcomes achieved with the original research-grade product. While the allogeneic DC product has been evaluated in pancreatic cancer models, its therapeutic potential extends to a broad range of solid tumors.

"These findings demonstrate that our vector optimization strategy maintains therapeutic potency while bringing our allogeneic DC platform to the threshold of IND-enabling studies," said David Weinstein, CEO of Lunai Bioworks. "This represents an important inflection point as we move from research innovation to clinical translation—positioning Lunai at the forefront of next-generation cell-based immunotherapies."

The full article, titled "Modified Hematopoietic Stem Cell-Derived Dendritic Cell Therapy Retained Tumor-Inhibitory Function and Led to Regression of Primary and Metastatic Pancreatic Tumors in Humanized Mouse Models," is available in Vaccines (View Source).

With enrollment completed and encouraging immune response data observed in the Phase 1 trial, Anixa plans to advance the vaccine into a Phase 2 clinical trial and will assume full sponsorship of the IND. The IND, currently sponsored by Cleveland Clinic, is in the process of being transferred to Anixa. The DTA will allow for the transfer of all relevant data and information, collected and generated from the Phase 1 clinical trial, to Anixa.

Anixa’s breast cancer vaccine, developed in collaboration with Cleveland Clinic, targets α-lactalbumin—a lactation-associated protein that is typically expressed only in breast tissue during lactation, but which re-emerges in many forms of breast cancer. By establising an immune response against α-lactalbumin-expressing cells, the vaccine may offer both therapeutic and preventive benefits for patients with tumors expressing this protein.

"Execution of the DTA represents a significant step in the transfer of IND sponsorship to Anixa. We look forward to completing the remaining steps with Cleveland Clinic, and eventually advancing to a Phase 2 trial under our sponsorship," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences. "We are pleased with the progress and preliminary findings from our Phase 1 clinical trial, and are excited about the presentation of the final Phase 1 data, by Cleveland Clinic, at the San Antonio Breast Cancer Symposium on December 11."

Presentation of the poster will be made in person on the following date and location:

Friday, November 7th,  12:15pm – 1:45pm ET; & 5:35pm – 7pm ET

Lower Level Atrium – Prince George’s ABC

Primary Category: Immuno-Conjugates and Chimeric Molecules

Abstract Number: 949

BACKGROUND:

Solid tumors remain largely unresponsive to immune checkpoint inhibitors, in part due to their ability to suppress the cytotoxic activity of immune cells infiltrating the tumor microenvironment. One of the disrupted pathways in these cancers is O-glycosylation, a feature particularly associated with cancer progression, metastasis, and poor prognosis.

One strategy to overcome resistance of solid tumor to immunotherapy is the employment of antibody-drug-conjugates (ADCs) selectively targeting cancer cells and not healthy tissues. We developed an ADC, designated PB-vcMMAE-5, composed of the following:

The monoclonal antibody (mAb): We used PB-223, an innovative mAb developed through affinity maturation of clinical stage mAb NEO-102 (Ensituximab), a chimeric human IgG1 mAb that targets truncated core 2 O-glycans, specifically expressed by cancer cells and not by healthy tissues. PB-223 does not bind to normal tissues and it internalizes into human cancer cell lines expressing its target.
The payload: Monomethyl auristatin E (MMAE) was used as payload. MMAE is a potent antimitotic agent that inhibits cell division by blocking the polymerization of tubulin and is the most common ADC payload used to be linked to antibodies in clinical development for oncologic applications.
The linker: mc-vc-PABc was used as a cleavable linker. PB-223 was conjugated to the linker-payload through a cysteine-based conjugation method.
The drug-to-antibody ratio (DAR) of PB-vcMMAE-5 is 3.92.

Study presented at SITC (Free SITC Whitepaper) Annual Meeting 2025 includes the following data:

PB-223 specific binding to human tumor tissues by immunohistochemistry (IHC): PB-223 binds selectively to human tumor tissues and not to human normal tissue. PB-223 strongly reacted with colorectal, pancreatic, lung, prostate, and ovarian tumor tissues.
In vitro  efficacy of PB-vcMMAE-5 against several human cancer cell lines: The in vitro cytotoxicity of PB-vc-MMAE-5 was evaluated in 9 human cancer cell lines, including prostate (PC-3, LnCAP), triple negative breast (HCC1937, MDA-MB-231), ER+,PR+,HER2+ breast (BT-474), squamous cell carcinoma of the lung (NCI-H226), ovarian (OV-90), colorectal (SW403), and pancreatic (CFPAC-1) cancer cell lines. This study shows that PB-vcMMAE-5 effectively killed all cell lines tested, with the highest percentage of killing observed against MDA-MB-231 (triple negative breast), LnCAP (prostate), OV-90 (ovarian), and NCI-H226 (lung) cancer cell lines.
In contrast, naked PB-223 mAb showed no killing in all cell lines tested.

In vivo safety of PB-vcMMAE-5 in mice: NOD-SCID mice bearing OV-90 (ovarian) xenografts were treated with weekly doses of PBS, MMAE alone, or PB-vc-MMAE-5 (1, 3, 6, or 9 mg/kg) for five weeks. Animal body weight was monitored regularly, twice a week, as an indirect measure of toxicity. The ADC PB-vcMMAE-5 was well tolerated in mice. No sign of distress and no loss of body weight were observed.
No significant changes in body weight, blood parameters including hematology and clinical chemistry, nor pathological changes in the liver, spleen, brain, or heart of mice treated with efficacious doses of the ADC were observed compared with control groups.
In vivo  efficacy of PB-vcMMAE-5 in mice: The efficacy of the ADC PB-vcMMAE-5 was assessed in OV-90 (ovarian) subcutaneous xenograft model established in NOD-SCID mice. The ADC PB-vcMMAE-5 was administered intravenously at doses 1, 3, 6 or 9 mg/kg, once per week for five weeks.
On day 31 from the first ADC infusion, most alive mice were sacrificed, and tumors were excised for histological analysis using Ki-67 staining to assess proliferating viable tumor cells. To further assess systemic toxicity and prolonged efficacy, three mice each from the 6 and 9 mg/kg groups were followed to day 45.

Data presented in this study show that PB-vcMMAE-5 induced significant tumor growth inhibition compared to controls in a dose-dependent manner.
The highest tumor growth inhibition was observed at 6 and 9 mg/kg doses.

In addition, analysis of tumors at day 45 showed absence of viable tumor cells and presence of tumor cells in necrosis, in mice treated with PB-vcMMAE-5 at 9 mg/kg.
Findings from this study showed that PB-vcMMAE-5 can kill human cancer cells expressing PB-223’s target, is not toxic in vivo in mice, and is highly effective in vivo at 9 mg/kg in NOD-SCID mice bearing human ovarian cancer. In addition, in a poster presented at AACR (Free AACR Whitepaper) Annual Meeting 2025 we reported that PB-vcMMAE-5 is stable in human plasma.

All these data suggest that PB-vcMMAE-5 has promising potential as a therapeutic option for a range of human malignancies expressing core 2 O-glycans.
