This agreement represents a significant milestone for Senhwa as CX-5461 enters the immuno-oncology field, and it also underscores the company’s commitment to advancing strategic combination therapies that break through the limitations of immunotherapy —bringing new hope to cancer patients worldwide.

Senhwa Biosciences: Driving a New Era in Immuno-Oncology

"This agreement represents a major step forward for Senhwa as we expand into the heart of immuno-oncology," said Benny T. Hu, Chairman of Senhwa Biosciences. "By leveraging the unique mechanism of action of CX-5461 in modulating the tumor microenvironment, we hope to discover and confirm new treatment options for patients who do not currently benefit from existing treatment options, while increasing international recognition and building long-term strategic value for the company," added by Chairman Hu.

Under the terms of the agreement, BeOne Medicines will provide tislelizumab for the combination study, while Senhwa will supply CX-5461 and lead clinical and regulatory operations. The study will enroll patients at multiple sites in the United States and Taiwan, assessing safety, tolerability, and preliminary efficacy of the CX-5461 plus tislelizumab combination.

By modulating the tumor microenvironment, CX-5461 breaks through the barriers of immunotherapy, opening new possibilities for cancer treatment

Discovered and developed by Senhwa, CX-5461 is the world’s first G-quadruplex stabilizer with significant clinical data—a novel therapeutic class designed to selectively disrupt genomic stability in tumor cells through replication stress induction.

Recent preclinical and clinical findings suggest that CX-5461 not only exerts direct cytotoxic activity but also modulates the tumor microenvironment, enhancing immune recognition and response.

By converting immunologically "cold" tumors into "hot" ones, CX-5461 may sensitize previously resistant tumors to checkpoint blockade and broaden the clinical utility of immunotherapy.

The "cold-to-hot" tumor concept represents one of the most promising frontiers in cancer immunology. CX-5461’s differentiated mechanism positions Senhwa to play a leading role in improving the efficacy of the immune checkpoint inhibitors approved by FDA with only 20-30% response rates.

Global Immunotherapy Market: Expanding Horizons

According to Precedence Research, the global cancer immunotherapy market is expected to grow from USD 136.4 billion in 2025 to USD 338.4 billion by 2034, representing a compound annual growth rate (CAGR) of 10.65%. Similarly, Grand View Research projects that the broader immunotherapy market will exceed USD 486 billion by 2030.

As major pharmaceutical companies approach a looming patent cliff—most notably with the immune checkpoint inhibitor blockbuster KEYTRUDA, which is expected to lose its exclusivity in 2028—the industry is ramping up efforts to secure next-generation immuno-oncology assets through strategic partnerships, mergers, and acquisitions.

With its differentiated pipeline, established collaboration with the U.S. National Cancer Institute (NCI), and now entering the supply agreement with BeOne Medicines, Senhwa Biosciences is uniquely positioned at the intersection of scientific innovation and global capital markets. The company aims to play a pivotal role in the next wave of expansion and innovation in precision medicine and immuno-oncology by partnering with global pharmaceutical companies and to drive sustainable growth and long-term value creation for its stakeholders.

The research teams developed multimodal models to more precisely stratify recurrence risk in early-stage breast cancer. The models integrate histopathologic imaging, clinical, and molecular data generated from TAILORx, one of the world’s largest and most rigorously annotated breast cancer research repositories. This level of multimodal integration is unprecedented at this scale in early breast cancer prognostication.

Early-stage breast cancer represents a large and heterogeneous patient population in which treatment decisions frequently hinge on uncertain recurrence risk. Of the approximately 310,720 new cases diagnosed in the United States each year, an estimated 60% are early-stage (American Cancer Society), underscoring the broad application and clinical relevance of more accurate and individualized risk assessment.

"Realized through collaboration between ECOG-ACRIN, NCI, and Caris Life Sciences, this public-private partnership represents a methodological, logistical, and collaborative integration of datasets from the historically impactful TAILORx trial to further extend the benefits for breast cancer patients," said ECOG-ACRIN Group Co-Chair Peter J. O’Dwyer, MD. "The advance in personalized medicine afforded in this work, in turn, helps to advance the potential of AI to refine treatment and improve outcomes."

Across analytic evaluations, the multimodal AI models demonstrated enhanced prognostic performance compared to existing recurrence-risk assessment methods, highlighting their potential to support more personalized treatment decision-making in early-stage breast cancer.

"By integrating imaging, clinical data, and molecular profiling, we are advancing beyond single-dimension diagnostics to deliver a more precise and comprehensive understanding of recurrence risk in breast cancer," said Caris EVP and Chief Medical Officer George W. Sledge, Jr., MD. "The development of these models underscores the transformative power of multimodal AI and machine learning in precision oncology."

Both AI models-including development approaches, integrated biomarker features, and demonstrated prognostic improvements- were presented in today’s SABCS sessions.

Multimodal Artificial Intelligence (AI) Models Integrating Image, Clinical, and Molecular Data for Predicting Early and Late Breast Cancer Recurrence in TAILORx, presented by Joseph A. Sparano, MD (Mount Sinai Tisch Cancer Center). Late-Breaking Abstract GS1-08 was presented during SABCS General Session 1.

In this project, researchers developed and prospectively validated a multimodal model integrating pathomic imaging (I), clinical (C), and expanded molecular (M+) data from 4,462 TAILORx tumor specimens. The expanded M+ gene expression panel includes 42 tumor genes associated with breast cancer recurrence derived from five commercially available gene assays, including the Oncotype DX (ODX) 21-gene recurrence score and a set of highly variable genes. Based on the results of the TAILORx trial, ODX is widely used in clinical practice for its prognostic information on recurrence and predictive information on chemotherapy benefit; however, its ability to forecast recurrence beyond the 5-year mark is limited.

The findings from this study will ultimately provide crucial support for the development of a new diagnostic test for women with HR-positive, HER2-negative, node-negative breast cancer that more accurately estimates recurrence risk, especially late recurrence 5 or more years after diagnosis.

"Although the TAILORx trial was the first randomized trial to establish the role of the 21-gene recurrence score to guide chemotherapy use in early breast cancer, our goal was to take one step further in personalizing cancer therapy by developing a new diagnostic test using tumor specimens derived from the trial," said Dr. Sparano.

Dr. Sparano noted that the team developed an AI model that evaluates not only tumor gene expression but also uses deep learning of digitized H&E slides used for routine pathologic assessment to provide better prognostic information about cancer recurrence risk.

"We found that the expanded gene panel was a strong predictor of early recurrence within 5 years after diagnosis, the pathomic imaging was a strong predictor of late recurrence after 5 years, and when combined, a test which added both features to the prognostic information provided by clinicopathologic factors was the strongest predictor of distant recurrence out to 15 years," he said.

A Multimodal-Multitask Deep Learning Model Trained in NSABP B-42 and Validated in TAILORx for Late Distant Recurrence Risk in HR+ Early Breast Cancer, presented by Eleftherios (Terry) Mamounas, MD, MPH (NSABP Foundation, Inc. and AdventHealth Cancer Institute). Abstract RF3-07 was presented during SABCS Rapid Fire Session 3.

Patients with early-stage, hormone receptor–positive (HR+) breast cancer are at risk for distant recurrence several years after diagnosis and initial treatment, making long-term risk assessment critical. Assessment of clinical factors alone (tumor size, grade, node status) is insufficient for precise risk stratification. Furthermore, there is a lack of personalized tools to guide decisions about the use of extended endocrine therapy (EET) beyond the standard 5 years.

Dr. Mamounas presented a multimodal–multitask deep learning algorithm designed to estimate late distant recurrence (DR) risk and help identify patients most likely to benefit from EET. Originally developed and validated in the NSABP B-42 randomized phase 3 trial, the model demonstrated strong prognostic performance, identifying those with minimal recurrence risk after a standard 5-year course of adjuvant endocrine therapy who could be spared additional treatment.

The ECOG-ACRIN/Caris research team conducted a new external validation study of the model in 4,300 patients from the TAILORx trial. In TAILORx, the model demonstrated robust late distant recurrence prognostication independent of other known prognostic factors, supporting its potential clinical utility as a scalable, cost-effective alternative to genomic assays using routine H&E and clinical data.

On December 10, 2025 Diakonos Oncology Corp., a clinical-stage biotechnology company developing a new generation of immunotherapies to treat challenging and aggressive cancers, reported that the Company was selected for a Product Development Research Grant through The Cancer Prevention and Research Institute of Texas (CPRIT), an award valued at more than $7 million. The Company was selected for funding as one of nine awardees out of 164 applicants for its proposal titled ‘Advancing DOC1021: Phase 1/2 Refractory Melanoma Study,’ which aims to expand DOC1021 into early-stage clinical development in a third target indication.

"We are honored to have CPRIT’s support as we bring DOC1021 into a new and critically underserved indication," said Jay Hartenbach, President and COO of Diakonos Oncology. "Across more than two dozen preclinical tumor models and multiple clinical indications, our personalized dendritic cell vaccine platform has shown a consistent pattern of potent immune activation and efficacy. With CPRIT’s support, we are now able to evaluate whether these same immune mechanisms can also benefit patients with refractory melanoma, a population with significant unmet medical need."

Melanoma is a serious and often aggressive form of skin cancer that arises from melanocytes, the pigment-producing cells in the skin. While many cases can be treated effectively when detected early, some patients experience disease progression despite available therapies such as immune checkpoint inhibitors or targeted therapies. In the case of refractory melanoma, the disease no longer responds to immune checkpoint inhibitors, resulting in limited options and poor clinical outcomes. Diakonos’ planned Phase 1/2 study will evaluate the safety and preliminary efficacy of DOC1021, along with ctDNA and immune biomarker responses, in this particularly high-need patient population.

"Despite the remarkable progress made with targeted therapies and immune checkpoint inhibitors, patients with refractory melanoma still have very limited options," said Ryan J. Sullivan, MD, Director of the Cutaneous Medical Oncology Program at Massachusetts General Brigham Cancer Institute. "DOC1021’s personalized dendritic cell approach, which presents each patient’s own tumor antigens in a viral-mimicking context, offers a compelling new way to re-engage the immune system against tumors that have escaped standard therapies. This trial will allow us to rigorously evaluate whether that biology can translate into meaningful benefit for this high-risk patient population."

Enrollment in the Phase 1 clinical study of DOC1021 for patients with refractory melanoma is expected to begin in January 2026, representing an important step forward in the Company’s efforts to advance this investigational therapy into early-stage clinical development.

About DOC1021

DOC1021 is a first-in-class, patient-derived double-loaded dendritic cell therapy that uniquely combines tumor lysate and amplified tumor-derived mRNA. The immunotherapy is made with a patient’s dendritic cells combined with mRNA and proteins prepared from freshly obtained patient tumor specimens.

The unique double-loading approach, which mimics a viral infection, unlocks a synergistic and exponentially more powerful tumor killing TH1 response driven by dual protein and RNA antigen sourcing, and it allows targeting of the complete cancer antigen pool. Moreover, the approach does not require any molecular modification of the patient’s immune cells for manufacturing and does not require preconditioning chemotherapy or high dose IL-2 for administration. DOC1021 allows for simple administration in the outpatient setting and broad reach via community cancer centers.

Diakonos currently has two active clinical trials with DOC102, a Phase 1 pancreatic cancer study (NCT04157127) and a Phase 2 glioblastoma (GBM) study (NCT06805305). Diakonos has received Fast Track designations from the FDA for both the GBM and pancreatic cancer programs, in October 2023 and May 2024, respectively. The company also received Orphan Drug Designation for the GBM program in January 2024. The refractory melanoma Phase 1/2 study with DOC1021 will be initiated with the facilitation and support of the Cancer Prevention and Research Institute of Texas (CPRIT).

On December 9, 2025 Clarity Pharmaceuticals (ASX: CU6) ("Clarity" or "Company"), a clinical-stage radiopharmaceutical company with a mission to develop next-generation products that improve treatment outcomes for patients with cancer, reported the acceptance of an abstract and poster on the Phase II DISCO trial (NCT04438304)1 data exploring 64Cu-SARTATE in patients with known or suspected neuroendocrine tumours (NETs) to the prestigious American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Gastrointestinal (GI) Cancers Symposium 2026 held on the 8-10th January. The abstract is titled "Diagnostic performance of 64Cu-SARTATE compared to 68Ga-DOTATATE in patients with known or suspected neuroendocrine tumors with focus on liver findings".

The data to be presented builds on some of the previously announced results2 that 64Cu-SARTATE positron emission tomography (PET) / computed tomography (CT) lesion detection was substantially higher than that of the current standard-of-care (SOC), 68Ga-DOTATATE PET/CT. 64Cu-SARTATE was deemed safe and well tolerated. Out of 45 participants enrolled in the trial, only seven (15.6%) trial participants experienced a total of nine 64Cu-SARTATE-related adverse events: eight were Grade 1 and one was Grade 2, with most resolving within 2 days.

The mean number of lesions detected by 64Cu-SARTATE was approximately double that observed with 68Ga-DOTATATE (441 vs. 227 lesions, respectively; averages across readers and both PET/CT timepoints for 64Cu-SARTATE). Overall, a total of 238 discordant lesions (lesions that were only detected by one of the scans, either 64Cu-SARTATE or 68Ga-DOTATATE PET/CT) were identified in 34 subjects with scan pairs across all body regions, representing a large difference between detection abilities of the two agents. Of these discordant lesions, 223 were detected by 64Cu-SARTATE alone and only 15 by 68Ga-DOTATATE alone. Importantly, for the 122 discordant lesions with evaluable standard of truth ([SOT] biopsy and/or follow-up conventional imaging), the difference in sensitivity between the agents was highly significant, favouring 64Cu-SARTATE (the sensitivities of 64Cu-SARTATE vs. 68Ga-DOTATATE were 94.7% [95% CI 65.1, 99.5] and 5.4% [95% CI 0.5, 34.9], respectively; p<0.001). This clearly demonstrates the considerable difference in sensitivity between 64Cu-SARTATE and SOC imaging, based on lesions detected by either of the agents, showing that 64Cu-SARTATE detected significantly more additional true-positive lesions compared to 68Ga-DOTATATE in the same patients.

New data which is being presented at ASCO (Free ASCO Whitepaper) GI shows that the liver had the highest number of lesions detected by both tracers among all organs/regions assessed: 64Cu-SARTATE PET/CT scans showed 352 lesions while 68Ga-DOTATATE PET/CT only showed 180 lesions. The liver is the most common metastatic site for patients with gastroenteropancreatic (GEP)-NETs, and hepatic metastatic burden is clinically important as it is strongly associated with patient outcomes and significantly influences the clinical management of the disease3. Therefore, the enhanced diagnostic performance offered by 64Cu-SARTATE, especially in key organs such as the liver, may allow clinicians to make treatment decisions with a greater degree of accuracy and confidence, with direct impact on patient outcomes. A Phase III study of 64Cu-SARTATE is being planned.

Clarity’s Executive Chairperson, Dr Alan Taylor, commented, "We are thrilled to continue generating valuable data, building further evidence of the best-in-class potential of our pipeline of products in development. As we are moving SARTATE towards commercialisation, it highlights our commitment to developing products for cancer indications with high unmet needs.

"Patients with NETs are often misdiagnosed and experience delays in receiving the correct diagnosis, which may lead to the identification of their cancer at later stages4. Visualising NET lesions earlier and more accurately at various stages of disease, especially in a critical organ like the liver, may have a significant impact on patient outcomes as it equips clinicians with crucial information on disease burden, helping to determine an optimal treatment plan.

"There are currently two key approved agents in the NETs PET imaging space, 68Ga-DOTATATE and 64Cu-DOTATATE, and both have substantial limitations when it comes to providing accurate and timely disease identification. These two products utilise the same chelator (i.e. cage), called DOTA, to hold diagnostic radioisotopes, while binding somatostatin receptor 2 (SSTR2), which is highly expressed in NETs. The key difference between the two agents is the isotope used to image patients, gallium-68 or copper-64. As we have seen with 68Ga-DOTATATE in the DISCO trial, its sensitivity was very low among discordant lesions, meaning several lesions would go undetected until they grew larger in size, if at all. This limitation is primarily due to the short half-life of gallium-68 which underpins the requirement for imaging within 1 hour post-administration. We have seen first-hand that once radiopharmaceutical products are administered, they take time to find the lesion whilst also needing to clear from non-target organs, providing greater contrast, known as tumour-to-background ratio5. Having greater contrast is especially important to identify smaller or more difficult to find cancers. This is where the benefits of using copper-64 with its longer half-life play an important role. However, despite using copper-64, 64Cu-DOTATATE has an important disadvantage where the DOTA chelator leaks copper in vivo6. Free copper-64 isotopes then accumulate in the liver, creating substantial background noise on PET scans which renders identification of lesions in the liver challenging. This is a key drawback with important clinical implications, as the presence of liver metastatic lesions is a notable prognostic factor in survival of these NET patients3.

"64Cu-SARTATE offers considerable advantages compared to approved SSRT2-targeted imaging agents, addressing some of their fundamental limitations and potentially providing patients and clinicians a chance to more accurately identify disease. As with all our products, we continue to rely on strong scientific foundations to develop 64Cu-SARTATE, design its clinical trials and progress the agent towards commercialisation. While employing the same SSTR2 targeting molecule as the existing competitors, which have established safety and efficacy, we have circumvented the issue of copper leakage with the sarcophagine (SAR) cage, enabling optimal imaging timepoints. The proprietary SAR Technology, developed through outstanding Australian benchtop science from the Australian National University and the University of Melbourne, is able to securely hold copper, ensuring there is minimal background in the liver. The combination of optimal imaging timepoints, enabled by copper-64, and secure chelating of the isotopes, made possible by the SAR Technology, is what clearly differentiates 64Cu-SARTATE from the competition, with the benefit of earlier and/or more accurate identification of lesions in NETs.

"With the improved diagnostic performance of 64Cu-SARTATE, based on data generated to date, and the potential of improving treatment outcomes of patients with NETs through reliable and accurate disease identification, we are already planning a registrational Phase III trial of 64Cu-SARTATE in NETs, aiming to expedite this unique agent to market."

About DISCO trial
DISCO is a "Diagnostic Imaging Study of 64COpper-SARTATE Using PET on Patients with Known or Suspected Neuroendocrine Tumours". It assessed the performance of Clarity’s SARTATE imaging product as a potential new method to diagnose and manage NETs. The trial aimed to build on earlier clinical experience with 64Cu-SARTATE in patients with NETs, which demonstrated that the diagnostic has excellent imaging characteristics and suggested that 64Cu-SARTATE PET/CT provides comparable or superior lesion detection to 68Ga-DOTATATE PET/CT in all patients, especially in the liver5.

DISCO recruited 45 participants with Gastroenteropancreatic NETs (GEP-NETs) across 4 sites in Australia, comparing the diagnostic performance of 64Cu-SARTATE PET at an average of 4 hours (between 3 and 5 hours) and approximately 20 hours post-administration (same-day and next-day imaging, respectively) to the current SOC, 68Ga-DOTATATE PET. Out of the 45, there were 41 participants with known NETs and 4 cases of suspected NETs. Most subjects had stage 3 or 4 disease.

Participants were required to have undergone a pre-study 68Ga-DOTATATE PET/CT scan within 5 weeks, but not closer than 6 hours prior to the administration of 64Cu-SARTATE as part of their routine clinical care.

About SARTATE
SARTATE is a next generation, highly targeted theranostic radiopharmaceutical. It is being developed for diagnosing, staging and subsequently treating cancers that express SSTR2, such as NETs. Like all Clarity products, the SARTATE product can be used with copper-64 (64Cu) for imaging (64Cu-SARTATE) or copper-67 (67Cu) for therapy (67Cu-SARTATE).

Disclaimer
64Cu-SARTATE is an unregistered product. The safety and efficacy of 64Cu-SARTATE have not been assessed by health authorities such as the US Food and Drug Administration or the Therapeutic Goods Administration. There is no guarantee that this product will become commercially available.

About NETs
NETs, also known as well-differentiated neuroendocrine neoplasms or carcinoids, represent a heterogeneous group of malignant transformations of cells of the diffuse neuroendocrine system7. They most commonly occur in the gastrointestinal tract (48%), lung (25%), and pancreas (9%), but may also originate in other areas, including the breast, prostate, thymus and skin8. NETs can either be benign or malignant, as well as non-functional and functional9. NETs traditionally have been considered uncommon; however, the incidence has been increasing as a worldwide phenomenon10.

Overall, it is estimated that more than 20,000 people in the United States are diagnosed with a NET each year11, and approximately 190,000 people are living with this diagnosis12. Patients with NETs present with subtle clinical symptoms, which can lead to a delay in diagnosis of more than 4 years13. As such, about 30-75% of NETs patients have distant metastases at the time of diagnosis14. A 10-year relative survival rate for patients with metastatic GEP-NETs is 3–36%.
