"Vir Bio delivered incredible momentum during the first quarter with positive, new VIR-5500 Phase 1 data and execution of a global agreement with Astellas in prostate cancer. The closing of our collaboration with Astellas in April has ignited the next stage of development work, bolstering our ability to move faster and think bigger together," said Marianne De Backer, Chief Executive Officer of Vir Biotechnology. "We also announced promising updated Phase 2 data on our combination regimen in CHD and will be presenting complete Week 96 data at the EASL Congress later this month. CHD is the most severe form of hepatitis. We believe our well-tolerated combination regimen is uniquely positioned to change the standard of care, bringing together robust efficacy with the potential for self-administration at home with once monthly subcutaneous dosing."

Pipeline Programs

Chronic Hepatitis Delta (CHD)

The Company will present additional data from the Phase 2 SOLSTICE trial evaluating the combination of tobevibart and elebsiran for CHD at the EASL Congress taking place May 27-30, 2026.
Earlier this year, the Company reported Phase 2 SOLSTICE data showing that the monthly combination of tobevibart and elebsiran was highly efficacious and well-tolerated. Undetectable hepatitis delta virus RNA (HDV RNA Target Not Detected, TND) was achieved and maintained by 77% (24/31) of participants receiving the combination regimen at Week 72. This rate increased to 88% (21/24) in the subset of participants evaluated through Week 96.
Topline data from the Phase 3 ECLIPSE 1 trial are expected in the fourth quarter of 2026.
Topline data from the ECLIPSE 2 and ECLIPSE 3 trials are expected in the first quarter of 2027.
Solid Tumors

VIR-5500

The Company closed its global strategic collaboration with Astellas to advance PSMA-targeted, PRO-XTEN dual-masked TCE VIR-5500 for the treatment of prostate cancer.
The first patient was dosed in the Phase 1 dose-expansion cohorts evaluating the safety, pharmacokinetics and preliminary efficacy of VIR-5500 in prostate cancer. The first expansion cohort will evaluate VIR-5500 monotherapy in Q3W 800/2000/3500 µg/kg step-up dosing in late-line metastatic castration-resistant prostate cancer (mCRPC). The Company anticipates initiating pivotal Phase 3 trials in 2027.
Positive updated Phase 1 data for VIR-5500 monotherapy showed dose-dependent anti-tumor activity and a well-tolerated safety profile in patients with mCRPC. The data were presented in an oral presentation at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Genitourinary Cancers Symposium.
VIR-5818

Phase 1 dose-escalation of VIR-5818, a HER2-targeted PRO-XTEN dual-masked TCE, in combination with pembrolizumab continues, with response data expected in the second half of 2026.
VIR-5525

The Phase 1 study of VIR-5525, an EGFR-targeted PRO-XTEN dual-masked TCE, continues enrollment as expected.
Preclinical Pipeline Candidates

The Company is currently progressing a number of PRO-XTEN masked TCEs in preclinical studies directed at clinically validated targets with potential applications across a variety of solid tumors, including lung, colorectal and bladder.
Corporate Update

The Company completed a follow-on public offering of common stock with gross proceeds of $172.5 million, before deducting underwriting discounts and commissions and offering expenses.
First Quarter 2026 Financial Results

Cash, Cash Equivalents and Investments: As of March 31, 2026, the Company had $809.3 million in cash, cash equivalents and investments, representing an increase of approximately $27.7 million during the first quarter of 2026. During the first quarter of 2026, the Company completed a public offering of its common stock with gross proceeds of $172.5 million, before deducting underwriting discounts and commissions and offering expenses.

Research and Development (R&D) Expenses: R&D expenses for the first quarter of 2026 were $108.9 million, which included $6.0 million of non-cash stock-based compensation expense, compared to $118.6 million for the same period in 2025, which included $7.0 million of non-cash stock-based compensation expense. The decrease was primarily driven by a $30.0 million expense in the first quarter of 2025 in connection with signing the restated Alnylam agreement, partially offset by higher CHD contract manufacturing costs associated with process performance qualification batches in preparation for commercialization, and to a lesser extent, higher clinical expenses from the progression of both our CHD and oncology programs in the first quarter of 2026.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses for the first quarter of 2026 were $23.3 million, which included $6.1 million of non-cash stock-based compensation expense, compared to $23.9 million for the same period in 2025, which included $7.1 million of non-cash stock-based compensation expense.

Net Loss: Net loss for the first quarter of 2026 was $125.7 million, or $0.85 per share, basic and diluted, compared to a net loss of $121.0 million, or $0.88 per share, basic and diluted for the same period in 2025.

2026 Financial Guidance

Based on our current operating plans, including the net effects of the Astellas global collaboration, the Astellas equity investment and the completion of the recent equity financing, the Company expects its cash, cash equivalents and investments to fund operations into the second half of 2028.

Conference Call

Vir Biotechnology will host its first quarter 2026 financial results conference call at 4:30 p.m. ET / 1:30 p.m. PT today. A live webcast will be available at View Source and will be archived for 30 days.

About the ECLIPSE Registrational Program

ECLIPSE is a registrational program to evaluate the safety and efficacy of tobevibart in combination with elebsiran in patients with chronic hepatitis delta (CHD). ECLIPSE includes three randomized, controlled trials designed to evaluate the combination therapy in comparison to deferred treatment or bulevirtide. ECLIPSE 1 (NCT06903338) is a Phase 3 trial evaluating the safety and efficacy of tobevibart in combination with elebsiran compared to deferred treatment in the U.S. or other regions where bulevirtide use is limited. ECLIPSE 2 (NCT07128550) is a Phase 3 trial evaluating the efficacy and safety of switching to tobevibart and elebsiran in people with CHD who have not achieved viral suppression with bulevirtide therapy. ECLIPSE 1 and 2 are designed to provide the registrational efficacy and safety data needed for potential submission to global regulatory agencies. ECLIPSE 3 (NCT07142811) is a Phase 2b head-to-head trial evaluating combination tobevibart and elebsiran compared with bulevirtide in bulevirtide-naïve patients, and it is designed to provide important supportive data to help establish access and reimbursement in key markets.

About Tobevibart and Elebsiran

Tobevibart is an investigational broadly neutralizing monoclonal antibody (mAb) targeting the hepatitis B surface antigen (HBsAg). It is designed to inhibit the entry of hepatitis B and hepatitis delta viruses into hepatocytes and to reduce the level of circulating viral and subviral particles in the blood. Tobevibart was identified using Vir Biotechnology’s proprietary mAb discovery platform. The Fc domain has been engineered to increase immune engagement and clearance of HBsAg immune complexes and incorporates Xencor’s Xtend technology to extend half-life. Tobevibart is administered subcutaneously, and it is currently in clinical development for the treatment of patients with chronic hepatitis delta.

Elebsiran is an investigational hepatitis B virus-targeting small interfering ribonucleic acid (siRNA) licensed from Alnylam Pharmaceuticals, Inc. It is designed to degrade hepatitis B virus RNA transcripts and limit the production of HBsAg. Current data indicate that it has the potential to have direct antiviral activity against hepatitis B virus and hepatitis delta virus. Elebsiran is administered subcutaneously, and it is currently in clinical development for the treatment of patients with chronic hepatitis delta.

About Chronic Hepatitis Delta (CHD)

CHD is the most severe form of chronic viral hepatitis2 and was recently classified as carcinogenic by the International Agency for Research on Cancer.3 People living with the disease rapidly progress to cirrhosis, liver failure4 and liver-related death.2 There are currently no approved treatments in the U.S., and options are limited in the European Union and globally.

About VIR-5500, VIR-5818 and VIR-5525

VIR-5500, VIR-5818 and VIR-5525 are investigational, clinical candidates currently being evaluated for the treatment of solid tumors. These assets leverage the universal PRO-XTEN masking technology and target PSMA, HER2 and EGFR, respectively.

TCEs are powerful anti-tumor agents that can direct the immune system, specifically T-cells, to destroy cancer cells. The universal PRO-XTEN masking technology is designed to keep the TCEs inactive (or masked) until they reach the tumor microenvironment, where tumor-specific proteases cleave off the mask and activate the TCEs, leading to killing of cancer cells by T-cells. By confining the activity to the tumor microenvironment, we aim to circumvent the traditionally high toxicity associated with TCEs and increase their efficacy and tolerability. Additionally, the mask is designed to help drug candidates stay in the bloodstream longer in their inactive form, allowing them to better reach the site of action and potentially allowing less frequent dosing regimens for patients and clinicians.

About Advanced Prostate Cancer

Prostate cancer remains a significant global health burden, representing the second leading cause of cancer-related mortality in men behind lung cancer.5 While diagnostic and therapeutic advances like androgen-directed therapy can improve outcomes in earlier settings, most patients ultimately relapse and develop metastatic hormone sensitive prostate cancer (mHSPC).6 mHSPC is characterized by its responsiveness to intensified hormonal interventions designed to reduce androgen levels or block their action. The majority of these patients eventually progress to metastatic castration-resistant prostate cancer (mCRPC).7 This stage is associated with poor clinical outcomes, including limited durability of existing therapies, with a 5-year survival rate of approximately 30%.8 There is a critical need for safer, more effective, and precisely targeted therapies capable of improving long term disease control and quality of life across the prostate cancer continuum.

(E,E)-bisantrene Discovered to Function via Silencing of c-MYC Expression

On May 6, 2026 Racura Oncology, an Australian Phase 3 stage clinical biopharmaceutical company, reported the discovery of the primary mechanism of action (MOA) of its lead oncology asset, (E,E)-bisantrene. Bisantrene has a long clinical history of activity across a range of cancer indications, but its mechanism of action has been unknown.

Preclinical studies undertaken by Racura and collaborators identified that (E,E)-bisantrene exerts its anticancer activity by binding to and stabilizing G-quadruplex (G4) DNA and RNA structures, key regulatory elements involved in controlling oncogene expression.

At the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2026, Racura presented new preclinical data demonstrating that (E,E)-bisantrene directly binds and stabilizes G4 DNA structures within the c-MYC gene promoter region, resulting in potent suppression of c-MYC expression and broad cytotoxic activity in a wide range of cancer models.[1][2]

The MYC protein functions as a master regulator of gene expression, governing thousands of genes involved in cell growth, differentiation, survival, metabolic reprogramming, chemotherapy resistance, and immune surveillance.[3] Crucially, MYC is the most commonly deregulated oncogene across human cancers, and has often been referred to as the ‘holy grail’ of targets due to its prevalence across many cancer indications. The promoter region of the c-MYC gene contains G4 DNA structures, which can suppress MYC expression when stabilized by drug binding.[4]

Race Oncology CEO and Managing Director, Dr Daniel Tillett said, "The discovery that (E,E)-bisantrene acts primarily by binding to G4-DNA structures leading to the inhibition of c-MYC expression fundamentally changes our thinking on how to best use this drug in the clinic.

This body of work significantly advances our understanding of (E,E)-bisantrene and highlights its potential as a best-in-class therapy targeting a central driver of cancer, MYC dysregulation."

"2026 is off to a strong start, with expanding usage of ZUSDURI (mitomycin) for intravesical solution and clear acceleration across key commercial indicators, including prescriber trial and adoption," said Liz Barrett, President and Chief Executive Officer of UroGen. "These trends reflect growing clinical confidence in ZUSDURI as a primary, non-surgical therapy for adults with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). The early launch momentum is now translating into meaningful revenue growth, providing early validation of our commercial model and reinforcing the blockbuster potential for ZUSDURI. In parallel, we continue to advance our broader pipeline, including next generation products UGN-103 in LG-IR-NMIBC and UGN-104 in low-grade upper tract urothelial carcinoma (LG-UTUC), as well as UGN-501, our investigational, potentially best-in-class, next-generation oncolytic virus. With this momentum, we are well positioned to execute our long-term growth strategy and continue to expand our leadership position in uro-oncology."

Q1 2026 and Recent Business Highlights:

ZUSDURI (mitomycin) for intravesical solution:

Commercial launch of ZUSDURI continues to accelerate, following its U.S. FDA-approval as the first and only FDA-approved medicine for adults with recurrent LG-IR-NMIBC.
The permanent Healthcare Common Procedure Coding System Level II J Code (J9282) became effective on January 1, 2026 and has enabled broader adoption by improving reimbursement clarity and confidence across both hospital and community settings.
ZUSDURI achieved net product revenue of $29.2 million in the first quarter of 2026, representing 109% quarter-over-quarter growth. The accelerating growth trend in prescribers, particularly repeat prescribers, reflects increasing health care provider confidence and successful integration of ZUSDURI into routine urology practice. As of March 31, 2026, UroGen reported:
972 activated sites of care
256 unique ZUSDURI prescribers
103 repeat ZUSDURI prescribers
Updated results from the Phase 3 ENVISION trial evaluating ZUSDURI were published online ahead of print in the Journal of Urology. The publication reported that patients who achieved a complete response (CR) three months after the first instillation of ZUSDURI had a 72.2% probability of remaining event-free 24 months after CR (95% CI: 64.1%, 78.8%) as determined by Kaplan-Meier analysis.
JELMYTO (mitomycin) for pyelocalyceal solution in LG-UTUC:

Generated net product revenue of $21.7 million in the quarter ended March 31, 2026, an increase of approximately 7% over the $20.3 million reported for first quarter of 2025.
Next-generation novel mitomycin-based formulations for urothelial cancer

UroGen plans to submit a New Drug Application (NDA) for UGN-103 (mitomycin) for recurrent LG-IR-NMIBC in the second half of 2026 with potential FDA approval in 2027. The FDA has agreed with the Company’s regulatory plan to submit the NDA based on the data from the Phase 3 UTOPIA trial. Top line results from UTOPIA were reported in November 2025, demonstrating a 77.8% three-month CR rate (95% CI, 68.3%, 85.5%). For more information on the UTOPIA trial, refer to clinicaltrials.gov/NCT06331299.
UGN-103 is a next-generation mitomycin product designed to offer improvements over ZUSDURI, including a shorter manufacturing process and simplified reconstitution procedure. It combines UroGen’s RTGel technology with a novel mitomycin formulation licensed from medac. UroGen continues to evaluate lifecycle management and pipeline expansion opportunities, including potential applications in high-grade NMIBC settings and adjuvant use of UGN-103 in IR-NMIBC patients.
The Phase 3 clinical trial to explore the safety and efficacy of UGN-104 is ongoing and is expected to be fully enrolled by the end of 2026. UGN-104 is a next-generation mitomycin product for LG-UTUC. For more information on the UGN-104 Phase 3 trial (UT002), refer to View Source
UGN-501 (investigational next-gen oncolytic virus) for use in high-grade non-muscle invasive bladder cancer

UGN-501 is a potent and fast-replicating investigational next-generation oncolytic virus being developed as a locally administered cancer treatment. Investigational New Drug (IND)-enabling studies are nearing completion, and UroGen plans to submit an IND in the second quarter of 2026 and initiate a Phase 1 clinical trial in NMIBC by year end. Nonclinical data to date demonstrate cytotoxic activity across a panel of bladder cancer cell lines representing a broad range of tumor stages and grades. The Phase 1 trial will initially evaluate aqueous intravesical administration of UGN-501, and UroGen plans to evaluate delivery using its proprietary RTGel technology, which may enable prolonged dwell time and enhanced local activity. The initial focus is bladder cancer with the potential to expand into additional tumor types beyond the genitourinary system.
Expanded Debt Facility with Pharmakon Advisors

In February 2026, UroGen entered into an amended and restated loan agreement with Pharmakon Advisors for two additional tranches of senior secured term loans. The first tranche of $200 million was funded at closing to refinance the existing $125 million loan facility and provide additional non-dilutive capital. A second tranche of $50 million may be drawn at the Company’s option no later than June 30, 2027, subject to customary conditions. All outstanding loans with Pharmakon Advisors will accrue interest at a fixed rate of 8.25% and be repaid in four equal quarterly payments commencing in the second quarter of 2030. All outstanding loans with Pharmakon Advisors can be prepaid in whole at UroGen’s discretion at any time, subject to prepayment premiums, make-whole amounts, as applicable, and fees.
American Urological Association Key Opinion Leader Panel to Showcase Real-World Experience with ZUSDURI

UroGen will host a KOL panel at the upcoming AUA Annual Meeting focused on real-world experience with ZUSDURI, including patient selection, workflow integration, treatment patterns, and patient outcomes. The event will feature leading urologists highlighting the role of ZUSDURI as a primary, non-surgical treatment option in recurrent low-grade intermediate-risk NMIBC and will be webcast and accessible through the Company’s website. To register click here.
First quarter 2026 Financial Results

Revenue: Total revenue was $51.0 million in the first quarter ended March 31, 2026, compared with $20.3 million in the first quarter of 2025. Year-over-year revenue growth of 152% was primarily driven by the commercial launch of ZUSDURI and JELMYTO revenue growth.

Research and Development (R&D) Expenses: R&D expenses were $15.6 million in the first quarter of 2026, including non-cash share-based compensation expense of $0.8 million. This compares to $19.9 million, including non-cash share-based compensation expense of $0.6 million, for the same period in 2025. The decrease in R&D expenses was primarily attributable to the acquisition of UGN-501 in the first quarter of 2025 and ZUSDURI manufacturing costs, which were recognized as R&D expense in the first quarter of 2025 prior to receiving FDA approval.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $51.5 million in the first quarter of 2026, including non-cash share-based compensation expense of $3.9 million. This compares to $35.0 million, including non-cash share-based compensation expense of $2.5 million, for the same period in 2025. The increase in SG&A expenses was primarily attributable to ZUSDURI commercial activities, including the sales force expansion following ZUSDURI approval and higher brand marketing expenses, an increase in overall commercial operation costs, and higher advisory costs, including fees associated with the Pharmakon Advisors debt refinancing in the first quarter of 2026.

Financing on Prepaid Forward Obligation: UroGen reported non-cash financing expense related to the prepaid forward obligation to RTW Investments of $4.5 million in the first quarter of 2026 compared with $4.6 million in the same period in 2025.

Interest Expense on Long-term Debt: Interest expense related to long-term debt was $4.2 million in the first quarter of 2026, compared to $4.1 million in the same period in 2025. The increase in interest expense was primarily attributable to the additional borrowings of $75.0 million in the first quarter of 2026 in connection with the Pharmakon refinancing of long-term debt, offset by the lower interest rate.

Net Loss: UroGen reported a net loss of $23.6 million or ($0.47) per basic and diluted share in the quarter ended March 31, 2026, compared with a net loss of $43.8 million or ($0.92) per basic and diluted share in the first quarter of 2025.

Cash, Cash Equivalents and Marketable Securities: As of March 31, 2026, cash, cash equivalents and marketable securities totaled $140.3 million.

2026 JELMYTO Revenue and Company Operating Expense Guidance: The Company continues to expect 2026 net product revenue for JELMYTO to be in the range of $97 million to $101 million. This implies a year-over-year growth rate of approximately 3% to 7% over the $94 million of JELMYTO revenue reported in 2025. The Company is not providing full-year 2026 revenue guidance for ZUSDURI at this time, as the product remains in the early stages of its commercial launch. The Company continues to expect full-year 2026 operating expenses to be in the range of $240 million to $250 million, including non-cash share-based compensation expense of $20 million to $24 million.

Conference Call & Webcast Information: Members of UroGen’s management team will host a live conference call and webcast today at 10:00 AM Eastern Time to review UroGen’s financial results and provide a general business update.

About ZUSDURI

ZUSDURI (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, approved for the treatment of adults with recurrent LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel technology, a sustained release, hydrogel-based formulation, ZUSDURI is delivered directly into the bladder in an out-patient procedure by a trained healthcare professional using a urinary catheter to enable the treatment of tumors by non-surgical means.

APPROVED USE FOR ZUSDURI

ZUSDURI (mitomycin) for intravesical solution is a prescription medicine used to treat adults with a type of cancer of the lining of the bladder called low-grade intermediate risk non-muscle invasive bladder cancer (LG-IR-NMIBC) after previously receiving bladder surgery to remove a tumor that did not work or is no longer working.

IMPORTANT SAFETY INFORMATION

You should not receive ZUSDURI if you have a hole or tear (perforation) of your bladder or if you have had an allergic reaction to mitomycin or to any of the ingredients in ZUSDURI.

Before receiving ZUSDURI, tell your healthcare provider about all of your medical conditions, including if you:

have kidney problems.
are pregnant or plan to become pregnant. ZUSDURI can harm your unborn baby. You should not become pregnant during treatment with ZUSDURI. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with ZUSDURI.

Females who are able to become pregnant: You should use effective birth control (contraception) during treatment with ZUSDURI and for 6 months after the last dose.

Males being treated with ZUSDURI: You should use effective birth control (contraception) during treatment with ZUSDURI and for 3 months after the last dose.
are breastfeeding or plan to breastfeed. It is not known if ZUSDURI passes into your breast milk. Do not breastfeed during treatment with ZUSDURI and for 1 week after the last dose.
How will I receive ZUSDURI?

You will receive your ZUSDURI dose from your healthcare provider 1 time a week for 6 weeks into your bladder through a tube called a urinary catheter. It is important that you receive all 6 doses of ZUSDURI according to your healthcare provider’s instructions.
If you miss any appointments, call your healthcare provider as soon as possible to reschedule your appointment.
During treatment with ZUSDURI, your healthcare provider may tell you to take additional medicines or change how you take your current medicines.
After receiving ZUSDURI:

About JELMYTO

JELMYTO (mitomycin) for pyelocalyceal solution is a mitomycin-containing reverse thermal gel containing 4 mg mitomycin per mL gel indicated for the treatment of adult patients with LG-UTUC. It is recommended for primary treatment of biopsy-proven LG-UTUC in patients deemed appropriate candidates for renal-sparing therapy. JELMYTO is a viscous liquid when cooled and becomes a semi-solid gel at body temperature. The drug slowly dissolves over four to six hours after instillation and is removed from the urinary tract by normal urine flow and voiding. It is approved for administration in a retrograde manner via ureteral catheter or antegrade through nephrostomy tube. The delivery system allows the initial liquid to coat and conform to the upper urinary tract anatomy. The eventual semisolid gel allows for chemoablative therapy to remain in the collecting system for four to six hours without immediately being diluted or washed away by urine flow.

APPROVED USE FOR JELMYTO

JELMYTO is a prescription medicine used to treat adults with a type of cancer of the lining of the upper urinary tract including the kidney called low-grade Upper Tract Urothelial Cancer (LG-UTUC).
