Dr. Jason Yang, CEO, President of R&D, and Executive Director at CStone, stated, "Based on the latest clinical data for CS2009, we are confident in its potential to transform treatment paradigms across a broad spectrum of tumor types. Driven by its unique molecular design, CS2009 offers key mechanistic differentiation. To date, approximately 200 patients have been enrolled, demonstrating an outstanding safety profile with no observation of the severe toxicities commonly associated with combination regimens containing CTLA-4 and PD-(L)1 inhibitors.

In terms of efficacy, CS2009 has delivered compelling results across multiple indications: as a monotherapy in first-line NSCLC, it achieved an ORR of 90% in patients with PD-L1 TPS ≥ 50%. Significant benefits were also observed in historically difficult-to-treat ‘cold tumors’, including IO-pretreated advanced NSCLC, non-clear cell renal cell carcinoma (nccRCC), and soft tissue sarcoma (STS). Furthermore, Phase II studies evaluating CS2009 in combination with standard chemotherapy for first-line NSCLC, CRC, and other indications have yielded high objective response rates.

We look forward to presenting additional Phase I and Phase II data at this year’s ASCO (Free ASCO Whitepaper) and/or ESMO (Free ESMO Whitepaper) congresses. Currently, we are engaged in advanced partnership discussions with several global multinational pharmaceutical companies and aim to initiate multiple Phase III MRCT by the end of 2026."

Rapid Patient Enrollment with Phase I/II Data Supporting Favorable Safety and Efficacy

The global multi-center Phase I/II clinical trial for CS2009 is actively ongoing in Australia and China, and its Investigational New Drug (IND) application for Phase II has been approved by the U.S. Food and Drug Administration (FDA). As of mid-March 2026, a total of 113 patients with advanced solid tumors have been enrolled in Phase I, with a median follow-up of approximately six months. 85 patients have been enrolled in Phase II.

1. Phase I Data Reinforces an Excellent Safety Profile:

CS2009 demonstrates a favorable safety and tolerability profile across all six dose levels evaluated, with no dose-limiting toxicities (DLTs) observed and the maximum tolerated dose (MTD) not reached.
The incidence of Grade ≥3 TRAEs was 23%; Grade ≥3 immune-related adverse events (irAEs) was 12.4%; and Grade ≥3 VEGF-related TRAEs was 4.4%. No excessive toxicities that typically occurred in combination therapies containing CTLA-4 and PD-(L)1 were observed.
2. Broad Antitumor Activity Observed in Heavily-Pretreated NSCLC and "Cold Tumors":
Antitumor activity was observed across all dose levels, with robust efficacy signals in multiple tumor types.

At the 30 mg/kg, Q3W, CS2009 monotherapy achieved an ORR of 25% (6/24) and a DCR of 58.3% (14/24) in AGA-negative, later-line NSCLC patients.
Across dose levels, CS2009 monotherapy resulted in an ORR of 40% and a DCR of 100% in patients with nccRCC (n=5).
Across dose levels, CS2009 monotherapy resulted in an ORR of 33.3% and a DCR of 66.7% in patients with STS (n=9).
Phase II Data Reveal Transformative Potential of CS2009: 90% ORR with Monotherapy in First-Line NSCLC and Excellent Tolerability in Combination Regimens for First-Line NSCLC and CRC

The global multi-center Phase II clinical trial employs a multi-cohort parallel expansion design to evaluate the efficacy and safety of CS2009 monotherapy and combination therapy across 15 cohorts in 9 solid tumor types, including NSCLC, CRC, extensive-stage small cell lung cancer (ES-SCLC), cervical cancer (CC), gastric or gastroesophageal junction cancer (GC/GEJC), esophageal squamous cell carcinoma (ESCC), platinum-resistant ovarian cancer (PROC), triple-negative breast cancer (TNBC), and hepatocellular carcinoma (HCC).

1. Monotherapy Shows Striking Efficacy in First-line NSCLC:
CS2009 monotherapy (20 mg/30 mg, Q3W) achieved an ORR of 90% (9/10) and a DCR of 100% (10/10) in first-line NSCLC patients with PD-L1 TPS≥50% (n=10).

2. Combination Therapies Demonstrate Favorable Tolerability and Promising Efficacy
Safety data from multiple cohorts of CS2009 combined with standard chemotherapy showed that the combinations were well-tolerated across tumor types, with CS2009 without increasing the incidence or severity of chemotherapy-related adverse events. Initial potent antitumor activity was observed with combination treatment in first-line NSCLC and first-line CRC.

Efficient and Clearly-Defined Global Development Strategy

CStone plans to initiate the first set of Phase III global MRCTs for CS2009 by the end of 2026, focusing on indications including NSCLC, CRC, and SCLC.

Additional Phase I and Phase II clinical data for CS2009 are expected to be presented at the 2026 ASCO (Free ASCO Whitepaper) and/or ESMO (Free ESMO Whitepaper) Annual Meetings.

About CS2009 (PD-1/VEGF/CTLA-4 Trispecific Antibody)

CS2009, an innovative trispecific antibody designed and developed by CStone, with the potential to be first- or best-in-class. It combines three clinically validated targets—PD-1, VEGFA, and CTLA-4—and exerts multidimensional antitumor effects through synergistic actions. Specifically, anti-PD-1 activity reverses T cell exhaustion, anti-CTLA-4 activity promotes T cell activation and proliferation, while anti-VEGFA activity blocks tumor angiogenesis and improves the tumor micro-environment (TME). In the TME, anti-PD-1 and anti-CTLA-4 activities are significantly enhanced by crosslinking with VEGFA. Meanwhile, CS2009 preferentially blocks PD-1 and CTLA-4 on double-positive tumor-infiltrating T cells while minimizing interference with CTLA-4 regulation in peripheral T cells.

Commercial Operations Enter a New Phase of Growth

In 2025, Akeso achieved record commercial sales revenue of RMB3,033.1 million, a 51.48% year-on-year increase. All approved products and indications are now included in China’s National Reimbursement Drug List (NRDL). The strong commercial growth in 2025 was fueled by strong clinical validation and widespread adoption by both healthcare professionals and patients.

By the end of 2025, several high-impact indications were added to the latest NRDL, including:

Ivonescimab: 1L PD-L1(+) NSCLC
Cadonilimab: 1L gastric cancer and 1L cervical cancer
Other products: Multiple indications for penpulimab, ebdarokimab and ebronucimab
With stable pricing for core first-line (1L) indications and improved hospital access, Akeso’s commercial platform is positioned for a transformative 2026.

Advanced Clinical Development of IO 2.0 Bispecifics

Ivonescimab (PD-1/VEGF):

As the world’s first and only approved PD-1/VEGF bispecific antibody, ivonescimab solidified its global leadership in 2025 by iterating upon existing Standards of Care (SOC) to reshape the oncology landscape. Ivonescimab has benefited approximately 70,000 patients to date.

Ivonescimab’s IO 2.0 value is anchored by a series of landmark Phase III victories: in the HARMONi-2 study, ivonescimab achieved a head-to-head win against pembrolizumab in 1L PD-L1(+) NSCLC, establishing a new "chemo-free" standard. Additionally, the HARMONi-A study marked it as the first immunotherapy to reach dual PFS and OS positivity in EGFR-TKI resistant NSCLC, while HARMONi-6 demonstrated its superiority over tislelizumab (anti-PD-1 monoclonal antibody) in combination with chemotherapy in 1L squamous NSCLC, successfully overcoming traditional anti-VEGF contraindications for squamous histology.

Currently, the U.S. FDA has accepted the BLA from our partner Summit Therapeutics for ivonescimab plus chemotherapy in nsq-NSCLC following third-generation EGFR-TKI failure. As the only commercialized PD-1/VEGF bispecific globally, ivonescimab has secured two approved lung cancer indications in China (both NRDL-listed) with another sNDA under review for the first-line treatment of advanced squamous NSCLC. The Company’s expansive global development program now encompasses 15 Phase III trials, including 5 global studies and 7 head-to-head studies against PD-1/L1 therapies, targeting critical 1L indications, IO-resistant, and "cold" tumors.

Cadonilimab (PD-1/CTLA-4):

Cadonilimab (PD-1/CTLA-4) is the world’s first and only approved bispecific antibody of its class. With approximately 120,000 patients treated to date, it has demonstrated "all-comer" clinical benefits across multiple tumor types. Its exceptional efficacy in treating challenging cases, such as IO-resistant and "cold" tumors, has solidified its status as a cornerstone therapy in the IO 2.0 era.

Akeso is advancing 12 registrational or Phase III clinical trials for cadonilimab globally, covering more than 10 major cancer types and spanning the full treatment lifecycle and clinical scenarios. Furthermore, the Company is spearheading two international registrational studies: a head-to-head Phase III trial against nivolumab in first line gastric cancer, and a registrational trial for IO-resistant hepatocellular carcinoma (HCC). These high-efficiency global studies aim to address significant unmet medical needs, further unlocking cadonilimab’s global therapeutic value.

Oncology Therapy Matrix Continues to Expand

Akeso is pioneering the IO 2.0 + ADC 2.0 strategy, expanding its portfolio from bispecifics into trispecifics and TCE platforms. the Company is fast-tracking the global development of its next-gen ADCs, such as the bispecific Trop2/Nectin4 AK146D1, and the HER3 AK138D1. By combining these with its core IO assets (cadonilimab and ivonescimab), Akeso aims to address the narrow therapeutic windows associated with traditional ADCs. With AK150 (trispecific) now in the clinic and more trispecific/multispecific antibodies and TCE bispecific/multispecific antibodies approaching clinical entry, Akeso is rapidly building a formidable, next-generation oncology matrix.

Paradigm Shift in Bispecific Excellence: Continuous Expansion of the Oncology Portfolio

Akeso is methodically extending its IO 2.0 leadership into the emerging ADC 2.0 landscape, thereby operationalizing its integrated "IO 2.0 + ADC 2.0" platform thesis while systematically advancing bispecific antibody expertise into higher order trispecific/multispecific antibodies and TCE platforms. In the area of IO, Akeso remains the sole global player with two approved immuno-oncology bispecifics, a distinction that confers both first-mover clinical validation and a proprietary data moat in dual-check point/dual-pathway blockade. On the ADC front, the Company’s next-generation candidates, notably bispecific ADC AK146D1 and novel ADC AK138D1, are purpose-engineered to overcome the narrow therapeutic window that chronically plagues current ADCs, advancing the field into ADC 2.0.

Phase II trials combining these proprietary ADCs with cadonilimab and ivonescimab are now underway, with global expansion planned. Both IO bispecifics are also being explored broadly with external high-potential ADCs. Meanwhile, the Company’s first trispecific antibody, AK150, is in clinical development, with more trispecific/multispecific and TCE assets approaching the clinic.

Immune and CNS Diseases Enter the Dual-Target Era

Beyond building global competitiveness in oncology, Akeso has created a powerful new growth engine in immune-related diseases. Leveraging its bispecific and multispecific antibody platforms, the Company is advancing a pipeline of novel candidates in autoimmune, respiratory, allergy, and CNS indications, including AK139, AK152 (siRNA), KF111 (siRNA), and KF115 (siRNA), alongside commercial-stage products like ebdarokimab, gumokimab and manfidokimab. This layered portfolio is rapidly strengthening Akeso’s global presence beyond oncology.

AI-Powered R&D and Cutting-Edge Platforms

Building atop its globally competitive command in monoclonal and bispecific antibody development, Akeso has executed a deliberate expansion into frontier therapeutic modalities by embedding AI end-to-end across the entire R&D and manufacturing continuum – from discovery and cell-line/process development through to smart manufacturing. The outcome is a tightly orchestrated portfolio of differentiated platforms: the Tetrabody antibody technology platform, the AI-powered drug R&D platform, the Dual-Shield ADC technology platform, the Dual-Lock T-cell engager (TCE) technology platform, the Tissue-Smart siRNA/mRNA technology platform, and the cell therapy technology platform. These assets collectively solidifies Akeso’s global innovation edge, unlocking 0-to-N breakthroughs across multiple high-barrier domains where conventional therapeutic modalities have historically stalled.

Akeso continues to iterate and scale its AI-powered, integrated drug discovery platform, which now provides comprehensive coverage across the entire R&D lifecycle for both antibody and nucleic acid therapeutics, while extending into additional frontier modalities. At its core lies a proprietary AI technology matrix that fuses high-precision structure prediction, immunogenicity prediction, fully automated humanization, and one-step sequence optimization. This closed-loop, data-rich architecture enables end-to-end precise engineering from sequence design to clinical development, significantly accelerating the efficient and high throughput development of innovative therapies.

Dr. Michelle Xia, Founder, Chairwoman, President, and CEO of Akeso, commented:

"2025 marked a definitive strategic leap for Akeso across commercialization, global clinical expansion, and our broadening multi-platform innovation ecosystem. We achieved over 50% sales revenue growth. This success provides a powerful springboard for continued commercial and clinical execution in 2026.

We are now pioneering a shift in therapeutic paradigms. Leveraging our leadership in IO bispecifics, we are expanding into ‘IO 2.0 + ADC 2.0,’ including bispecific ADCs, trispecifics, and TCE platforms. Beyond oncology, we are bringing the immense therapeutic benefit of bispecific antibodies to immunology, respiratory, and CNS diseases, all powered by our integrated AI discovery engine.

Our vision to bring transformative and life saving medicine to every patient on Earth is coming to fruition. With over ten products in international trials, including studies that includes ivonescimab and cadonilimab, we are advancing our mission to deliver world-class medicines to patients worldwide.

GLIX1 is an oral small molecule with a novel mechanism of action applicable to a broad range of cancers. By restoring TET2 activity, GLIX1 selectively targets DNA damage repair in cancer cells only. GBM was selected as the first indication for GLIX1 due to the low level of TET2 activity in this aggressive brain cancer, for which there remains a high unmet medical need for novel and more effective treatments. In extensive preclinical studies, including in-vivo GBM models, GLIX1 demonstrated potent anti-tumor activity and excellent blood-brain-barrier penetration, combined with a favorable safety profile in toxicology studies.

Three renowned academic centers will ultimately participate in this clinical trial. The first center ready to start enrolling patients is NYU Langone Health, led by Dr. Alexandra Miller. This will be followed by Northwestern University, led by Dr. Roger Stupp and Dr. Ditte Primdahl, and by Moffit Cancer Center, led by Dr. Patrick Grogan.

"The initiation of this study represents the culmination of many months of tireless work on behalf of our team and the team of our collaboration partner, Hemispherian AS, as well as a pivotal moment in our mission to identify and advance innovative drugs to treat diseases with significant unmet needs," stated Philip Serlin, Chief Executive Officer of BioLineRx. "GLIX1 has a very compelling profile supporting this Phase 1/2a study and, to that end, we look forward to initial data in the first half of 2027."

Dr. Alexandra Miller, Chief of Neuro-Oncology and Co-Director of the Brain and Spine Tumor Center at the Perlmutter Cancer Center, NYU Langone Health, stated, "I am pleased to be the first investigator able to enroll patients into this critical study, which brings new hope to patients who are in desperate need of innovative and novel treatment options."

Dr. Roger Stupp, Medical Director of the Malnati Brain Tumor Institute at Northwestern University in Chicago, and lead investigator of the study, added, "GLIX1 is a promising innovative molecule with impressive pre-clinical data, and I could not be more excited to participate in this study. The protocol will rigorously assess the safety of an agent with an entirely novel mechanism of action, with the potential to ultimately integrate well and synergize with the current treatments. We urgently need breakthrough innovations for our patients suffering from glioblastoma, one of the most aggressive and difficult malignancies to treat."

Phase 1/2a clinical trial design (NCT07464925)

The Phase 1 part of the trial is expected to recruit up to 30 patients with recurrent and progressive GBM and other high-grade glioma. The objective is to establish a maximum tolerated dose (MTD) and/or a recommended dose based on safety, PK/PD and preliminary efficacy. Data from the Phase 1 part of the trial are anticipated in H1 2027.

The Phase 2a expansion part of the trial is planned to include various population cohorts, including GBM (newly diagnosed and/or recurrent), as well as additional cancers with/without standard of care (e.g., PARP inhibitors). These cohorts are expected to identify preliminary efficacy, PD assessments and dose optimization data, serving as the basis for a rapid and effective advanced clinical development plan.

"2025 was a year of meaningful progress across our clinical programs, pipeline strategy and capital position," said Marvin White, President and Chief Executive Officer of Aptevo Therapeutics. "Most importantly, recently reported mipletamig data continue to demonstrate encouraging remission outcomes together with a favorable safety profile, including no cytokine release syndrome observed in frontline patients treated to date. These results support the potential for mipletamig to enhance frontline AML treatment alongside existing standard-of-care therapy."

White continued, "During the year we also expanded our CD3 pipeline, introduced our first trispecific programs and strengthened our access to capital to support continued execution. As I transition into the role of Executive Chair and Jeff Lamothe assumes the responsibilities of President and Chief Executive Officer, I am confident in the Company’s ability to build on this momentum."

Highlights

Aptevo entered 2026 with momentum:

Mipletamig Clinical Performance: Mipletamig in triplet combination therapy continues to outperform standard of care ven/aza 1 in unfit frontline patients with acute myeloid leukemia (AML). This further validates a differentiated safety profile, including no cytokine release syndrome in frontline patients, suggesting it is additive to the current standard of care

Expanded CD3 portfolio: the addition of three new multispecific candidates, leveraging the Company’s proprietary application of its differentiated CRIS7-derived CD3 binding domain, including the introduction of its first two trispecific assets

These additions emphasize the breadth and modularity of the ADAPTIR and ADAPTIR-FLEX platforms and position the Company to address a wider range of tumor targets and combination strategies across immune-oncology

Strengthened Financial Capacity: In 2026, the Company established a $60 million equity line facility, providing additional access to capital, subject to market conditions and the Company’s capital deployment strategy. If fully utilized, this facility, together with current resources, is expected to support operations into 2029.

Encouraging Frontline AML Data

Updated interim results from 28 evaluable frontline AML patients 2 treated with mipletamig in combination with ven/aza demonstrate an emerging clinical profile that is additive in combination with standard of care. The triplet regimen delivered an 86% clinical benefit rate, including a 79% CR/CRi (vs. 66% ) 1 remission rate and a 61% complete remission rate (vs.37%) 1.

Among patients achieving remission, 55% reached measurable residual disease-negative status. Notably, 35% of remissions occurred in patients with TP53 mutations, a high-risk biomarker typically associated with poor prognosis.

Importantly, no cytokine release syndrome has been observed in frontline patients treated to date. Outcomes from the mipletamig triplet compare favorably with historical results reported for the ven/aza doublet and support the potential for mipletamig to enhance frontline AML therapy for older and/or unfit patients.

"Mipletamig continues to demonstrate encouraging remission outcomes together with a consistently favorable safety profile," said Dirk Huebner, M.D., Chief Medical Officer of Aptevo Therapeutics. "The absence of cytokine release syndrome in frontline patients underscores the potential advantage of our differentiated CD3 design in combination treatment settings."

Huebner added, "Four patients treated to date have proceeded to allogeneic stem cell transplant, representing the most favorable treatment outcome in AML and an uncommon achievement in the older and/or unfit frontline population."

A Differentiated CD3 Platform

During 2025 Aptevo expanded its CD3 portfolio with three new multispecific candidates, including the Company’s first two trispecific drug candidates designed to address complex solid tumor microenvironments.

All programs leverage Aptevo’s proprietary CRIS-7-derived CD3 binding domain, designed to promote targeted T-cell activation while reducing systemic immune overstimulation. Clinical experience with mipletamig, now evaluated in more than 120 patients across three trials, provides early validation of this design approach.

The Company now has a five-molecule CD3 portfolio spanning hematologic malignancies and solid tumors, including programs targeting AML, prostate cancer and Nectin-4-expressing tumors.

Capital Strategy and Financial Flexibility

Aptevo ended 2025 with $21.6 million in cash and cash equivalents, compared with $8.7 million at December 31, 2024, and expects current resources to support operations into the fourth quarter of 2026.

In 2026, the Company also established a $60 million equity line with Yorkville Advisors Global, LP. The equity line provides financing flexibility and allows Aptevo to access capital opportunistically based on its needs and market conditions. The Company is not required to utilize the full capacity of the facility and continues to evaluate additional strategic and non-dilutive funding opportunities.

2025 Summary Financial Results

Cash Position: Aptevo had cash and cash equivalents as of December 31, 2025, totaling $21.6 million.

Research and Development Expenses: Research and development expenses was $14.5 million and $14.4 million for the years ended December 31, 2025, and 2024, respectively. The increase was primarily due to increased mipletamig and employee costs and was offset by lower costs on ALG.APV- 527 as we concluded the dose escalation trial.

General and Administrative Expenses: General and administrative expenses increased by $1.6 million, to $11.8 million for the year ended December 31, 2025, from $10.2 million for the year ended December 31, 2024. The increase is primarily due to higher employee, consulting, and legal costs.

Other Income Net: Other Income, net was $0.3 million for the year ended December 31, 2025, and other income, net was $0.5 million for the year ended December 31, 2024. The change was primarily due to lower interest and rental income.

Net Loss Attributable to Common Shareholders: For the years ended December 31, 2025, and 2024, Aptevo had a net loss of $26.0 million and $24.1 million, respectively. The Company recorded a dividend deemed attributable to down round feature of common warrants of $1.6 million in 2025. The basic and diluted net loss per share for the year ended December 31, 2025, was $87.27 per share, compared to $31,460.23 per share for the corresponding period in 2024.

Dividend Attributable to Down Round Feature of Warrants: This non-cash amount reflects the impact of reducing the exercise price of the Company’s June 2025 warrants from the original $58.50 per share to $19.01 per share, the lowest price at which we sold common shares after issuance of such common warrants due to contractual requirements of the warrants. The exercise price was further adjusted to the floor price of $11.70 as a result of additional shares of common stock sold in January 2026. The $1.6 million recorded in the year ended December 31, 2025, reflects dividend deemed to common shareholders and it increases net loss attributable to common shareholders to $27.5 million for EPS purposes.
