"This quarter we continued to make strong progress across our clinical pipeline," said Paul Peter Tak, M.D., Ph.D., FMedSci, President and CEO of Candel. "We continue to work toward a planned BLA submission in Q4 2026. We presented additional supportive data from our positive phase 3 trial of CAN-2409 in newly diagnosed, localized prostate cancer during an oral presentation at the Association of Radiation Oncology (ASTRO) Annual Meeting, demonstrating that CAN-2409 improved prostate cancer-specific DFS, independent of the type of external beam radiation therapy used, extending the results presented during an oral presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. We also presented data during an invited lecture at the Annual Meeting of the Prostate Cancer Foundation. We continue to follow the patients enrolled in the phase 3 study for prostate cancer-specific outcomes and expect the first results after extended follow-up in Q2 2026. In addition, in collaboration with the U.S. Food and Drug Administration, we designed a supportive, mechanistic clinical trial of CAN-2409 in localized prostate cancer. We plan to release immunologic biomarker data from this study in Q3 2026. Furthermore, we reported encouraging survival data from our phase 1b clinical trial of CAN-3110 in patients with rHGG, most of whom had recurrent glioblastoma, supported by sophisticated brain biopsy analyses. Mature overall survival data for Arm C are expected in Q4 2026. Together, the data supports the design of a randomized controlled phase 2 clinical trial of CAN-3110 in recurrent glioblastoma. Finally, we strengthened our Research Advisory Board with the appointments of Dr. Carl H. June and Dr. Bali Pulendran, underscoring our continuous commitment to scientific excellence and to advancing immunotherapies that may meaningfully improve the lives of patients with devastating cancers."

Dr. Tak continued, "On the financial front, we were pleased to secure strategic, non-dilutive funding through a five-year, $130 million term loan facility with Trinity Capital, Inc., which strengthens our balance sheet and positions us to advance our key priorities, including the initiation of a pivotal phase 3 clinical trial of CAN-2409 in NSCLC and the potential commercial launch of CAN-2409 in localized prostate cancer. We expect updated data on long-term survivors from our phase 2 study in NSCLC in Q1 2026 and anticipate initiation of the phase 3 study in Q2 2026. We look forward to sharing more details on our progress and strategic vision at our virtual Research and Development event in Q4 2025."

Third Quarter 2025 & Recent Highlights

•
CAN-2409 (aglatimagene besadenovec) – Prostate Cancer
•
In an oral presentation at the 2025 ASTRO Annual Meeting, the Company presented subgroup analyses focused on the radiation regimen used during its positive phase 3 clinical trial of CAN-2409 in patients with intermediate-to-high-risk localized prostate cancer. Data were presented by Glen Gejerman, M.D., M.B.A., Co-Director of Urologic Oncology at Hackensack Meridian Health and one of the principal investigators of the study.

•
CAN-2409 demonstrated statistically significant improvement in prostate cancer-specific DFS (Hazard Ratio (HR) 0.62; p=0.0046). Effects were observed with both moderate hypo-fractionated external beam radiation therapy (EBRT) (HR 0.52, CI 0.30 – 0.93, p=0.0236) and conventional EBRT (HR 0.76, CI 0.53 – 1.07, p=0.1131).
•
CAN-2409 administration was safe across radiation therapy modalities, with both conventional radiation therapy (~78 Gy in 2 Gy fractions, ~72% of patients) and moderate hypofractionated radiation therapy (60 Gy in 3 Gy fractions, ~25% of patients), showing similar tolerability profiles. Grade ≥ 3 treatment related adverse events were similar in the CAN-2409 plus valacyclovir and placebo arms with both hypofractionated (1.6% vs. 1.9%) and standard EBRT (1.8% vs. 1.1%), respectively.
•
The U.S. Food and Drug Administration (FDA) previously granted Fast Track Designation and Regenerative Medicine Advanced Therapy Designation to CAN-2409 for the treatment of prostate cancer; the phase 3 clinical trial of CAN-2409 in localized prostate cancer was conducted under a Special Protocol Assessment agreed to with the FDA.
•
The Company is advancing its pre-BLA readiness, including through its Chemistry, Manufacturing, and Controls (CMC) activities, and preparation of clinical study reports and BLA modules.
•
CAN-2409 – Non-Small Cell Lung Cancer (NSCLC)
•
Following a positive end-of-phase 2 meeting with the FDA in July 2025, the Company is preparing to initiate a pivotal phase 3 clinical trial of CAN-2409 in NSCLC in Q2 2026.
•
The FDA previously granted Fast Track Designation to CAN-2409 for the treatment of NSCLC.
•
CAN-2409 – Pancreatic Cancer
•
The Company previously generated encouraging data based on a randomized controlled phase 2a clinical trial of CAN-2409 in borderline resectable pancreatic cancer (PDAC). The FDA previously granted Fast Track Designation and Orphan Drug Designation to CAN-2409 for the treatment of PDAC and the European Medicines Agency granted Orphan Designation for CAN-2409 for the treatment of pancreatic cancer in July 2025.
•
With Candel’s top priorities focused on prostate cancer and NSCLC, the Company will pause the PDAC program, unless it is funded through external, non-dilutive funding.
•
CAN-3110 (linoserpaturev) – Recurrent High-Grade Glioma (rHGG)

•
In October 2025, the Company reported encouraging updated survival data for all patients enrolled in its phase 1b clinical trial of CAN-3110 in rHGG:
•
Updated median overall survival (mOS) was 11.8 months (CI: 8.3–14.9) for arm A (n = 41) and 12.0 months (CI: 10.0–NA) for arm B (n = 9) after a single injection of CAN-3110, consistent with previously reported data for arms A and B. At the time of data cutoff (August 15, 2025), one patient from arm A and one patient from arm B were still alive after prolonged follow-up (59.2 and 42.4 months, respectively, after CAN-3110 administration). The FDA previously granted Fast Track Designation and Orphan Drug Designation to CAN-3110 in recurrent high-grade glioma based on an earlier data cut.
•
At data cutoff as of August 15, 2025, 9 patients in arm C had received multiple administrations of CAN-3110. At the 1×10⁸ PFU dose, 3 patients received 4 injections, 1 patient received 5 injections, and 2 patients received 6 injections. At the 1×10⁷ PFU dose, 1 patient received 4 injections, and 2 patients received 5 injections. Median follow-up was 8.9 months. Four out of 9 patients were alive at time of data cutoff (range 3.1-28.2 months after initiation of CAN-3110 treatment). Five patients had died, of which 3 died more than one year after initiation of CAN-3110 treatment (range 5.5-21.8 months).
•
Candel also announced the scientific publication, "Serial Multiomics Uncovers Anti-Glioblastoma Responses Not Evident by Routine Clinical Analyses," in the journal Science Translational Medicine. Led by E. Antonio Chiocca, M.D., Ph.D., Executive Director of the Center for Tumors of the Nervous System at the Mass General Brigham Cancer Institute, as part of the multi-institutional Break Through Cancer Accelerating GBM Therapies Through Serial Biopsies TeamLab, the publication presents findings from the comprehensive analysis of 97 serial tumor biopsies collected from two patients treated with repeated administrations of CAN-3110 in arm C of the ongoing phase 1b clinical trial (NCT03152318).
•
Together, the encouraging data supports the Company’s plans to design a randomized controlled phase 2 clinical trial of CAN-3110 in recurrent glioblastoma.
•

Financial Results for the Third Quarter Ended September 30, 2025

Research and Development Expenses: Research and development expenses were $8.5 million for the third quarter of 2025 compared to $5.4 million for the third quarter of 2024. The increase was primarily due to an increase in manufacturing and regulatory costs, in support of the Company’s CAN-2409 programs, and an increase in employee-related expenses, as well as an increase in depreciation and loss on the disposal and sale of fixed assets. Research and development expenses included a non-cash stock compensation expense of $0.5 million for the third quarter of 2025 compared to a non-cash stock compensation expense of $0.6 million for the third quarter of 2024.

General and Administrative Expenses: General and administrative expenses were $4.7 million for the third quarter of 2025, compared to $3.3 million for the third quarter of 2024. The increase was primarily due to an increase in commercial readiness costs as well as an increase in employee-related expenses. General and administrative expenses included non-cash stock compensation expense of $0.6 million for the third quarter of 2025 compared to $0.5 million for the third quarter of 2024.

Net Loss: Net loss for the third quarter of 2025 was $11.3 million compared to a net loss of $10.6 million for the third quarter of 2024 and included net other income of $1.9 million and net other expense of $1.9 million, respectively. The change from net other expense in 2024 to net other income in 2025 was primarily related to the change in the fair value of the Company’s warrant liability and an increase in interest income.

Cash Position: Cash and cash equivalents, as of September 30, 2025, were $87.0 million compared to $102.7 million as of December 31, 2024. Based on current operating plans, including the initiation of a potentially registrational phase 3 trial in NSCLC, the Company expects that its existing cash and cash equivalents, as of September 30, 2025, together with proceeds from the upfront tranche of the Trinity debt facility, will be sufficient to fund operations into Q1 2027.

About CAN-2409

CAN-2409 (aglatimagene besadenovec), Candel’s most advanced multimodal biological immunotherapy candidate, is an investigational, off-the-shelf, replication-defective adenovirus designed to deliver the herpes simplex virus thymidine kinase (HSV-tk) gene to a patient’s tumor. After intratumoral administration, HSV-tk enzyme activity results in conversion of prodrug (valacyclovir) into deoxyribonucleic acid (DNA)-incorporating nucleotide analogs, leading to immunogenic cell death in cells exhibiting DNA damage and proliferating cells, with subsequent release of a variety of tumor (neo)antigens in the tumor microenvironment. At the same time, the adenoviral serotype 5 capsid protein promotes inflammation through the induction of expression of pro-inflammatory cytokines, chemokines, and adhesion molecules. Together, this regimen is designed to induce an individualized and specific CD8+ T cell-mediated response against the injected tumor and uninjected distant metastases for broad anti-tumor activity, based on in situ immunization against a variety of tumor antigens. CAN-2409 has the potential to treat a broad range of solid tumors. Encouraging monotherapy activity as well as combination activity with standard of care radiotherapy, surgery, chemotherapy, and immune checkpoint inhibitors have previously been shown in several preclinical and clinical settings. More than 1,000 patients have been dosed with CAN-2409 in clinical trials with a favorable tolerability profile to date, supporting the potential for combination with standard of care, when indicated.

About CAN-3110

CAN-3110 (linoserpaturev) is a first-in-class, replication-competent herpes simplex virus-1 (HSV-1) next-generation oncolytic viral immunotherapy candidate designed for dual activity for oncolysis and immune activation in a single therapeutic. In October 2023, the Company announced that Nature published results from the ongoing clinical trial where CAN-3110 was reported to be generally well tolerated with no dose-limiting toxicity. In the clinical trial, the investigators observed improved mOS compared to historical controls after a single CAN-3110 injection in this therapy-resistant condition.1 The Company and academic collaborators are currently supported by the Break Through Cancer foundation.

About the enLIGHTEN Discovery Platform

The enLIGHTEN Discovery Platform is a systematic, iterative HSV-based discovery platform leveraging human biology and advanced analytics to create new multimodal biological immunotherapies for solid tumors. The enLIGHTEN Discovery Platform has been designed to deconvolute the characteristics of the tumor microenvironment related to clinical outcomes. These characteristics are rapidly translated into optimized multi-gene payloads of tumor modulators that can be delivered to the tumor microenvironment for specific indications, disease stages, and rationally designed therapeutic combinations.

"In the third quarter, we remained focused on clinical execution in both our global Phase 3 CoMpass trial in early choroidal melanoma and our Phase 1b/2 trial in NMIBC," said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura Biosciences. "Enrollment has taken longer than we expected in early choroidal melanoma due to the requirement to document active tumor growth prior to patient enrollment and other unique enrollment challenges with the first Phase 3 trial in this rare indication. In 2025, we implemented measures to address these operational challenges and have experienced improved enrollment in recent months. We believe we are now in a position to provide guidance regarding the topline data readout for the study."

"Our NMIBC trial remains on track, with data expected in mid-2026. Recently presented Phase 1 trial immune profiling data reinforce bel-sar’s distinct dual mechanism, driving focal anti-tumor immune activation. We believe these findings highlight bel-sar’s potential as a differentiated frontline, organ-preserving treatment to deliver durable responses across the bladder cancer spectrum and in other solid tumors."

Recent Pipeline Developments

Early Choroidal Melanoma

Ongoing Phase 3 CoMpass Trial: CoMpass is the first registration-enabling trial in early choroidal melanoma. The trial is a global, Phase 3, randomized trial evaluating bel-sar treatment against a sham control arm utilizing an enrichment strategy to enroll approximately 100 patients with documented tumor growth. We believe the study enrollment has been slower than expected due to the operational challenges of implementing the first Phase 3 trial in this rare indication across global sites and the requirement of active growth in our inclusion criteria, which often requires sites to follow patients for variable periods of time until they demonstrate required growth.

Approximately 90% of targeted clinical sites are now activated, and we have implemented measures to address multiple operational challenges. Our patient identification tool has shown strong growth, with more than 400 patients having been entered since June 2024, and the current number of potentially eligible patients having increased to 280. We believe this highlights the enrollment opportunity and the significant unmet need.

Based on trial activity in recent months and the growing number of potentially eligible patients, the Company currently expects that it can complete CoMpass enrollment in 2026 and provide topline data readout for the 15-month primary endpoint in the fourth quarter of 2027. This estimate assumes enrollment rates that are generally consistent with the rates experienced in recent months.

Currently, there are no approved vision-preserving therapies for patients with early choroidal melanoma. The standard of care remains radiotherapy, which frequently results in irreversible vision loss. Bel-sar has the potential to become the first frontline vision-preserving therapy in this setting. The Company previously received Orphan Drug Designation from the FDA and the European Medicines Agency and Fast Track designation from the FDA for the treatment of early choroidal melanoma. The CoMpass trial is under a Special Protocol Assessment agreement with the FDA.

Bladder Cancer

Additional Phase 1 Biological Activity Data Presented at the 45th Congress of the Société Internationale d’Urologie (SIU): Multiplex immune fluorescence data from the Phase 1 trial of bel-sar demonstrating robust induction of adaptive immune memory in patients with non-muscle invasive bladder cancer (NMIBC) were presented by Seth P. Lerner, M.D., Professor of Urology at Baylor College of Medicine at SIU, held October 29–November 1, 2025, in Edinburgh, United Kingdom: link. These multiplex immune fluorescence data (n=5 patients from the Phase 1 trial) further characterize the previously announced results from the Company’s completed Phase 1 clinical trial of bel-sar in patients with NMIBC.

These data revealed that a single focal administration of bel-sar induced adaptive immune memory through generation of de novo mature tertiary lymphoid structures (TLS) in 3/5 participants evaluated. Bel-sar also generated innate and adaptive effectors regardless of immune environment and converted immune-cold or exhausted lesions into active, immune-hot microenvironments. In treated lesions, natural killer cell density increased up to 40x, CD4+ cytolytic T cell density increased up to 7x, and CD4+ and CD8+ memory T cells were observed after bel-sar treatment.

This biological activity profile reinforces bel-sar’s potential as a frontline therapy designed to treat the tumor, activate durable anti-tumor immunity, and reduce recurrence risk across the bladder cancer spectrum.

Ongoing Phase 1b/2 Trial: This trial will evaluate additional doses and cycles of bel-sar in approximately 26 intermediate and high-risk NMIBC patients. Patients will be monitored for response assessments and recurrence at 3, 6, 9, and 12 months. This trial is actively enrolling and remains on track, with initial three-month clinical data expected in mid-2026.

Metastases to the Choroid

The Company has dosed the first patient in an ongoing Phase 2 clinical trial in metastases to the choroid. A protocol amendment has now been implemented to expand the entry criteria to include all metastases arising from different solid tumors to facilitate enrollment into the study and broaden the proof of concept for bel-sar in this indication. This approach is supported by preclinical models that demonstrate robust efficacy across multiple primary solid tumors. The Company is evaluating further expansion of the inclusion criteria for this trial to address the high unmet medical need. With a four-week efficacy endpoint, the Company expects early proof of concept data from this trial in 2026.

Metastases to the choroid is an indication with high unmet medical need and no approved therapies with an incidence of 20,000 patients annually in the United States and Europe. Bel-sar has the potential to treat a wide variety of tumor types in the choroid that metastasize from various primary tumors. The Company previously received FDA Fast Track designation for bel-sar in this indication.

Cancers of the Ocular Surface

The Company is planning to initiate a Phase 1 proof-of-concept trial to assess safety, feasibility and tumor response through histopathologic evaluation at a 2–4-week time point. Development activities for this program remain on track, with early proof of concept data from Australian clinical sites expected in 2026.

Cancers of the ocular surface affect approximately 35,000 patients in the United States and Europe annually and are associated with a particularly high incidence in regions such as Australia. There are currently no approved therapies for these tumors.

Third Quarter 2025 Financial Results

•
As of September 30, 2025, the Company had cash and cash equivalents and marketable securities totaling $161.9 million. The Company believes its current cash and cash equivalents and marketable securities are sufficient to fund its operations into the first half of 2027. The Company remains focused on driving a cash-efficient operation to deliver data across its pipeline.

•
Research and development expenses increased to $22.2 million for the three months ended September 30, 2025 from $17.0 million for the three months ended September 30, 2024, primarily due to ongoing clinical and clinical research organization (CRO) costs associated with the progression of our global Phase 3 trial of bel-sar in early choroidal melanoma and higher personnel expenses related to growth of our Company.

•
General and administrative expenses decreased to $5.7 million for the three months ended September 30, 2025 from $6.2 million for the three months ended September 30, 2024. General and administrative expenses include $1.7 million and $1.6 million of stock-based compensation for the three months ended September 30, 2025 and 2024, respectively. The decrease was primarily driven by reduced professional fees.

•
Net loss for the three months ended September 30, 2025 was $26.1 million compared to $21.0 million for the three months ended September 30, 2024.

"The strength of our third quarter performance reflects our disciplined focus on executing strategic priorities," said Lindsay Androski, President and CEO of Arbutus. "We are also excited to share additional analysis of imdusiran clinical data being conducted as part of our ongoing strategic review. Notably, in addition to the eight patients who initially achieved functional cure with imdusiran at 60mg in our Phase 2a trials, forty more patients across all cohorts discontinued nucleos(t)ide analogue therapy after meeting study-defined criteria. In total, a combined 46% of all Phase 2a patients were able to discontinue all treatment. All but one patient who achieved functional cure or who we are following after discontinuing nucleos(t)ide analogue therapy remain off all treatment long-term, now exceeding two years for some patients. Across our Phase 1b and Phase 2a trials, imdusiran has demonstrated sustained benefits in chronic hepatitis B patients, regardless of baseline hepatitis B surface antigen levels, hepatitis B virus DNA presence or absence, and hepatitis B e-antigen positivity or negativity. We remain dedicated to accelerating the development and potential approval of imdusiran."

LNP Litigation

Arbutus continues to consult closely with and support its exclusive licensee, Genevant Sciences, to protect and defend Arbutus’s intellectual property, which is the subject of on-going lawsuits against Moderna and Pfizer/BioNTech. The Company, together with Genevant, is seeking fair compensation for Moderna’s and Pfizer/BioNTech’s use of Arbutus’s patented LNP technology that was developed with great effort and at a great expense, and without which Moderna’s and Pfizer/BioNTech’s COVID-19 vaccines would not have been successful.
In the Moderna U.S. litigation, fact discovery, expert discovery and summary judgment briefing have been completed. A jury trial is scheduled for March 2026. In March 2025, the Company, alongside Genevant Sciences, filed five international lawsuits against Moderna and its affiliates seeking to enforce patents protecting the Company’s patented LNP technology across 30 countries. Public oral hearings for two of the five cases which are before the Unified Patent Court are scheduled for May 2026, and a trial in the Canadian case is set to begin in September 2027.
The claim construction hearing for the lawsuit against Pfizer/BioNTech occurred in December 2024, and the court issued a claim construction ruling in September 2025, which construed the disputed claim terms in a manner the Company generally considers to be favorable.
Corporate Updates

The Company showcased four poster presentations featuring data from its hepatitis B virus (HBV) programs at AASLD 2025. One poster presented new analysis from the Company’s IM-PROVE I Phase 2a clinical trial showing beneficial clinical outcomes were observed across all evaluated HBV genotypes (A to E). The Company also had a Poster of Distinction highlighting AB-101’s maximal PD-L1 receptor occupancy between 68-100% at a 30mg daily dose.
Today, the Company published an updated Corporate Presentation on its website, which includes the results of its recently completed analysis of imdusiran clinical data.
In addition to the eight functional cures, an additional 40 patients across all cohorts in its Phase 2a trials met study-defined criteria for nucleos(t)ide analogue (NA) therapy discontinuation.
In total, 46% (48/105) of all Phase 2a patients either achieved functional cure or remained off NA therapy for at least 48 weeks after discontinuing NA therapy following treatment with imdusiran.
Eighteen patients consented to long-term follow-up, including all functionally cured patients and 10 patients who discontinued NA therapy. To date, 94% of those follow-up patients have remained off all treatment for between 58 to 109 weeks. One functionally cured patient seroreverted but remains virally suppressed and off all treatment.
Additionally, 56% (5/9) of Phase 1b patients (only received imdusiran and NA therapy) who elected to discontinue NA therapy, remained off all treatment for at least 3 years.
Imdusiran has also demonstrated steep and durable declines in HBV DNA, and, with NA therapy, achieved full HBV DNA suppression significantly faster than NA therapy alone. By week 18 of treatment with imdusiran and NA therapy, 100% of Phase 1b HBV DNA positive patients achieved HBV DNA levels below the level of quantification, The eight Phase 2a patients who achieved functional cure continue to have HBV DNA levels below the level of quantification.
In 30 hepatitis B e-antigen (HBeAg) positive patients in our Phase 1 and 2a trials, HBeAg decreased in all patients in a dose-dependent manner.
Financial Results

Cash, Cash Equivalents and Investments

As of September 30, 2025, the Company had cash, cash equivalents and investments in marketable securities of $93.7 million compared to $122.6 million as of December 31, 2024. During the nine months ended September 30, 2025, the Company used $35.0 million in operating activities, which included one-time payments related to its restructuring efforts. This was partially offset by $3.9 million of proceeds from the exercise of stock options.

Revenue

Total revenue was $0.5 million for the quarter ended September 30, 2025, compared to $1.3 million for the same period in 2024. The decrease of $0.8 million was due to a decrease in license royalty revenues, primarily due to a decline in Alnylam’s sales of ONPATTRO.

Operating Expenses

Research and development expenses were $5.8 million for the quarter ended September 30, 2025, compared to $14.3 million for the same period in 2024. The decrease of $8.5 million was due primarily to cost savings from the Company’s decisions to streamline the organization to focus its efforts on advancing the clinical development of imdusiran and AB-101, which included ceasing all discovery efforts, discontinuing its IM-PROVE III clinical trial, and reducing the Company’s workforce.

General and administrative expenses were $3.0 million for the quarter ended September 30, 2025, compared to $4.5 million for the same period in 2024. This decrease was due primarily to cost-cutting efforts by the Company, which drove reductions in employee compensation-related expenses and legal fees.

Restructuring costs in the quarter ended September 30, 2025 were $0.1 million, and all remaining restructuring-related payments are expected to be made by the first quarter of 2026.

Net Loss

For the quarter ended September 30, 2025, the Company’s net loss was $7.7 million, or a loss of $0.04 per basic and diluted common share, as compared to a net loss of $19.7 million, or a loss of $0.10 per basic and diluted common share, for the quarter ended September 30, 2024.

Outstanding Shares

As of September 30, 2025, the Company had 192.0 million common shares issued and outstanding, as well as 14.9 million stock options and unvested restricted stock units outstanding.

About Imdusiran (AB-729)

Imdusiran is an RNAi therapeutic specifically designed to reduce all hepatitis B viral proteins and antigens including HBsAg, which is thought to be a key prerequisite to enable reawakening of a patient’s immune system to control the virus. Imdusiran targets hepatocytes using Arbutus’ novel covalently conjugated N-Acetylgalactosamine ("GalNAc") delivery technology enabling subcutaneous delivery. To date, Arbutus has reported a total of eight patients with cHBV who have achieved a functional cure following treatment with imdusiran and NA therapy in combination with either IFN or low dose nivolumab plus an immunotherapeutic, with seven out of the eight patients continuing to sustain functional cure for over a year after treatment. An additional 40 patients across our Phase 2a clinical trials were able to remain off NA therapy for at least 48 weeks after discontinuing NA therapy following treatment with imdusiran. Clinical data generated thus far has shown imdusiran to be generally safe and well-tolerated, while also providing meaningful reductions in HBsAg and hepatitis B virus DNA.

About HBV

Hepatitis B is a potentially life-threatening liver infection caused by HBV. HBV can cause chronic infection which leads to a higher risk of death from cirrhosis and liver cancer. cHBV infection represents a significant unmet medical need. The World Health Organization estimates that over 250 million people worldwide suffer from cHBV infection, while other estimates indicate that approximately 2 million people in the United States suffer from cHBV infection. Approximately 1.1 million people die every year from complications related to cHBV infection despite the availability of effective vaccines and current treatment options.

"Tuspetinib in combination with VEN+AZA standard treatment (TUS+VEN+AZA) has been highly active and so well tolerated in newly diagnosed AML patients with 40 mg, 80 mg, and 120 mg TUS, we dose escalated to the 160 mg TUS dose level in the triplet," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer of Aptose. "Patients evaluated at the higher dose levels of 80 mg and 120 mg TUS have all (6/6; 100%) achieved CR/CRh responses, exceeding the 66% rate expected from VEN+AZA alone. We now are dosing at 160 mg TUS, and we look forward to providing further updates next month at ASH (Free ASH Whitepaper)."

Key Corporate Highlights

Tuspetinib Data Reported at European School of Haematology (ESH) 7th International Conference Data from the ongoing TUSCANY trial of tuspetinib in combination with venetoclax and azacitidine (TUS+VEN+AZA) were presented in a poster presentation, "TUSCANY Study of Safety and Efficacy of Tuspetinib plus Standard of Care Venetoclax and Azacitidine in Study Participants with Newly Diagnosed AML Ineligible for Induction Chemotherapy," at the European School of Haematology (ESH) 7th International Conference on Acute Myeloid Leukemia "Molecular and Translational": Advances in Biology and Treatment, held in October in Estoril, Portugal. Data from 10 patients in the TUSCANY trial across all three cohorts, 40 mg, 80 mg or 120 mg TUS dose in TUS+VEN+AZA, reveal promising clinical safety and antileukemic activity and support the use of TUS with standard of care treatment across a broad range of AML populations, including those carrying adverse mutations regardless of FLT3 mutation status.

As reported, the addition of TUS to VEN+AZA achieved CR/CRh responses in 6/6 (100%) patients treated at the higher dose levels of 80 mg and 120 mg TUS, exceeding the 66% rate expected from VEN+AZA alone. Overall, TUS+VEN+AZA has delivered CR/CRh responses in 9/10 (90%) patients. CR/CRh responses were achieved across diverse mutational subtypes including unmutated FLT3, FLT3-ITD, NPM1c, biallelic TP53 with complex karyotype, RAS, and myelodysplasia related mutations. MRD-negativity with TUS+VEN+AZA was observed in 7/9 (78%) of responding patients by central flow cytometry, and hematopoietic stem cell transplants (HSCT) have been completed in 2 patients to date.

Aptose Clinical Data Accepted for Poster Presentation at ASH (Free ASH Whitepaper) – Aptose was notified that its abstract, "TUSCANY Study demonstrates safety and efficacy of tuspetinib plus standard of care venetoclax and azacitidine in patients with newly diagnosed AML ineligible for induction chemotherapy," has been selected for poster presentation at the 67th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition. The meeting is scheduled to take place December 6-9, 2025, in Orlando, Florida. The abstract accepted for presentation can be viewed online at the ASH (Free ASH Whitepaper) conference website here, and will appear in the November supplemental issue of Blood. The actual presentation will include more recent updates and additional data not found in the abstract.

Research and development expenses decreased by $2.5 million to $2.2 million for the quarter ended September 30, 2025, as compared to $4.7 million for the comparable period in 2024. Changes to the components of our research and development expenses presented in the table above are primarily as a result of the following events:

Program costs for tuspetinib were $1.4 million for the quarter ended September 30, 2025, compared with $4.1 million for the comparable period in 2024. The lower program costs for tuspetinib in the current period are attributable to reduced activity in our APTIVATE clinical trial, reduced manufacturing activity, and related expenses.
Program costs for luxeptinib increased by approximately $0.3 million during the three months ended September 30, 2025 compared to the comparable period in 2024 due to a refund provided by one of our clinical vendors during the three months ended September 30, 2024.
The Company discontinued further development of APTO-253.
Personnel-related expenses decreased by $0.3 million due to lower headcount for research and development personnel in the current quarter.
Stock-based compensation increased by $0.1 million in the quarter ended September 30, 2025, compared to the comparable period in 2024, primarily due to forfeitures recognized during the three months ended September 30, 2024 in connection with employee terminations during the period.
Research and development expenses decreased by $7.7 million to $7.9 million for the nine months ended September 30, 2025, as compared to $15.6 million for the comparable period in 2024. Changes to the components of our research and development expenses presented in the table above are primarily as a result of the following events:

Program costs for tuspetinib were $5.1 million for the nine months ending September 30, 2025, compared to $10.7 million for the comparable period in 2024. The increased costs associated with the TUSCANY study were offset by a decrease in tuspetinib development expenses during the current period. This reduction is due to the conclusion of activities in our APTIVATE clinical trial during the current period, compared to higher APTIVATE activities during the nine months ended September 30, 2024, as well as lower manufacturing and related development costs.
Program costs for luxeptinib remained consistent during the nine months ended September 30, 2025 compared to the comparable period in 2024.
The Company discontinued further development of APTO-253.
Personnel-related expenses decreased by $2.0 million due to lower headcount for research and development personnel in the current quarter.
Stock-based compensation decreased by approximately $0.1 million in the nine months ended September 30, 2025, compared to the comparable period in 2024, primarily due to stock options forfeited and/or vested in prior periods that are no longer being expensed resulting in lower expense in the current period.
