Plans for Pediatric Clinical Trials

NanOlogy is completing Investigational New Drug (IND) enabling studies required by the U.S. Food and Drug Administration (FDA). Upon completion of these studies, the company plans to submit an IND application for LSAM-Cisplatin to treat malignant neoplasms of the brain including DIPG. Subject to FDA allowance to proceed, NanOlogy aims to initiate a clinical trial in late 2026 to evaluate the safety and response of stereotactic IT administration of LSAM-Cisplatin in children diagnosed with DIPG. According to DIPG.org, DIPG afflicts 150 – 300 children annually in the United States, with median survival of less than one year. Current treatments, like radiation therapy, may delay progression but almost always fail to deliver long term survival. NanOlogy is also assessing future opportunities to extend the use of LSAM-Cisplatin to treat other brain and solid tumors.

The Promise of LSAM-Cisplatin in DIPG

In laboratory research studies, cisplatin has been shown to kill DIPG tumors by binding to DNA and disrupting cell replication, leading to cell death. Unfortunately, current systemically administered cisplatin formulations are associated with numerous severe side effects throughout the body. In addition, cisplatin does not cross the blood brain barrier well, limiting its efficacy in brain tumors, making systemically administered cisplatin a suboptimal treatment for DIPG.

"We believe NanOlogy’s innovative LSAM-Cisplatin investigational drug designed for intratumoral administration can overcome the limitations of current treatment options with highly targeted delivery of drug into the tumor, continuous drug release, and minimal systemic toxicity," said H. Paul Dorman, founder and chairman of NanOlogy. "Advancements in minimally invasive surgical procedures and imaging now allow local delivery of LSAMs to solid tumors virtually anywhere in the body, including the brain. We are excited to advance IT LSAM-Cisplatin for DIPG and explore the promise it may hold for children and families facing this devastating disease."

Abstract ID: 242MO
Title: HCB101, a Differentiated SIRPα Fusion Protein, Demonstrates Favorable Safety and Early Antitumor Activity Across Solid Tumors and Lymphoma
First Author: Dr. Fangling Ning, Affiliated Hospital of Binzhou Medical University
Date / Time: 11 December 2025 / 11:45 – 12:45 GMT

"For nearly a decade, CD47 therapies were held back not by flawed biology but by flawed molecules, which struggled to balance safety and efficacy at the same time, especially in immunologically cold tumors," said Scott Liu, PhD, Founder, Chairman, and CEO of HanchorBio. "HCB101 was engineered from the ground up to solve that problem. Using AI-guided structural modeling, we identified three core mutations that reshape SIRPα’s interaction with CD47, allowing us to combine the strengths of first- and second-generation approaches into a single, differentiated molecule. Being selected as one of only 26 mini-oral presentations at ESMO (Free ESMO Whitepaper) Immuno-Oncology reinforces the field’s recognition of this effort and redefines the CD47 therapies. With its clean safety profile, strong target engagement, and early activity in cold tumors, HCB101 is emerging as a true macrophage-checkpoint backbone – much like the transformative PD-1/PD-L1 therapies that were based on T-cell checkpoint inhibition."

Key Findings Highlighted in the Mini-Oral

Monotherapy (HCB101-101; NCT05892718)

Clean, cytopenia-sparing safety across 12 cohorts up to 36 mg/kg QW
No bleeding events or immune-related toxicities, with the majority of treatment-related adverse events being Grade 1-2
Linear PK (T1/2 ~3 days) with receptor occupancy (RO) >99% at ≥8 mg/kg
Durable antitumor activity, including confirmed PRs in:
HNSCC -Head and neck squamous cell carcinoma (~42% tumor regression, ≥32 weeks)
MZL – Marginal zone lymphoma (~89% tumor regression, ≥16 weeks)
Stable disease ≥4-9 months across colorectal cancer (CRC), ovarian cancer, non-small cell lung cancer (NSCLC), and sarcoma
Combination Therapy (HCB101-201; NCT06771622)
Well-tolerated across gastric cancer (GC), triple-negative breast cancer (TNBC), CRC, and HNSCC
No new safety signals across all evaluated combinations
Cytopenias fully attributable to chemotherapy, not HCB101
2L GC:
58.3% ORR (7/12) for all cohorts evaluated, 77.8% ORR (7/9) for mid-dose cohorts, and 100% DCR
Tumor shrinkage up to -78.2%
1L HER2+ GC: 33% ORR (1/3)
1L TNBC: 50% ORR (3/6) and 100% DCR
Alvin Luk, PhD, MBA, CCRA, President & Chief Medical Officer (Group) and Chief Executive Officer (U.S.A.) of HanchorBio, added, "The early efficacy signals from HCB101 are unusually compelling for this stage of development. In second-line GC, where standard therapy achieves an ORR of about 27%, HCB101 combinations exceed 78% ORR, achieve 100% disease control, and result in tumor reduction approaching -78%. These results are not incremental; they meaningfully exceed expectations and reflect robust macrophage checkpoint engagement. With clean safety and sustained receptor occupancy, the data give us confidence to anchor development in second-line disease and expand into first-line and perioperative settings where depth and durability of response matter most."

About HCB101: A Next-Generation SIRPα Fc-Fusion Protein

HCB101 is a 3.5th-generation engineered SIRPα-Fc fusion protein with an intact IgG4 Fc backbone, developed using HanchorBio’s FBDB platform to selectively target tumor CD47 while minimizing binding to red blood cells. This design avoids the anemia and thrombocytopenia that limited early anti-CD47 programs, while preserving potent macrophage activation and downstream T-cell engagement. Key differentiators include:

Cytopenia-sparing safety up to 30-36 mg/kg
Receptor occupancy (RO) >99% at clinically active exposures
Strong macrophage and downstream T-cell activation
Broad antitumor activity across >80 PDX/CDX models and multiple clinical tumor types
Robust early combination efficacy in tumors that historically respond poorly to immunotherapy
Unlike earlier approaches, HCB101’s safety, target selectivity, and RO profile support its use as a macrophage-checkpoint backbone – analogous to how PD-1/PD-L1 inhibitors function as foundational T-cell backbones in oncology. HCB101 is designed for broad combinability across established and emerging treatment modalities, including:

Chemotherapy
Antibody-drug conjugates (ADCs)
Anti-PD-1/anti-PD-L1 checkpoint inhibitors
Anti-VEGF inhibitors
Anti-EGFR therapies
Anti-HER2 regimens
This versatility positions HCB101 as a modular, next-generational immuno-oncology component capable of enhancing the efficacy of multiple therapeutic backbones across solid tumors and hematologic malignancies.

"2025 was a transformational year for us, having initiated our accelerated approval Phase 3 trial of IFx-2.0 as an adjunctive therapy to Keytruda in front-line MCC, having completed the merger with Kineta bringing a Phase 2 ready VISTA inhibiting antibody to our pipeline and having presented data positioning the DOR as a promising new target in overcoming resistance to checkpoint inhibitors. We were pleased to raise $15 million in our June 2025 PIPE financing and warrant exercise earlier this year and the recently announced $15.6 million equity financing transaction providing us with a cash runway to accomplish multiple key milestones across all three development programs" said Dr. James Bianco, President and Chief Executive Officer of TuHURA Biosciences.

"We look forward in 2026 to the expected completion of enrollment for our Phase 3 study of IFx-2.0 in MCC, and anticipate receiving FDA clearance to initiate our randomized Phase 2 trial of physician’s choice of menin inhibitor vs a menin inhibitor+TBS-2025, our VISTA inhibiting antibody, in NPM1 mutated r/r AML. We also expect to present preliminary data from our IFx-2.0 basket trial; data on inhibiting DOR on MDSCs, TAMs and T regs at a scientific conference in 2Q; and proof-of-concept data in animal models for our lead ADC at a scientific conference in Q4 2026."

"In an encouraging development in our VISTA inhibiting antibody (TBS-2025) clinical program, at a mini symposium on December 5, 2025 prior to the ASH (Free ASH Whitepaper) meeting, several key opinion leaders, provided valuable insights and recommendations on our Phase 2 clinical trial plans for TBS-2025, in AML. There was clear enthusiasm for the potential of combining TBS-2025 with a menin inhibitor both in NPM1 r/r/ AML, in high-risk AML and in patients with AML who are unfit for intensive therapies. The KOLs noted that while menin inhibitors have become standard of care in NPM1 mutated AML, there still exists a significant unmet medical need, citing the relatively low CR rate and short duration of response as the two obstacles to improving clinical benefit in these patients."

Dr. Bianco continued, "The VISTA gene is the only checkpoint upregulated in patients with AML, notably among high-risk AML. It has been shown that VISTA expression on leukemic blasts is the primary culprit in the low response rate and short duration of response in AML. Targeting VISTA represents the first potential for immunotherapy to improve the treatment outcomes in AML, not just NPM1 mutated AML was the consensus opinion from the group," concluded Dr. Bianco.

Participants at the mini symposium included: Geoffrey Uy, MD, Co-chair of the Leukemia Committee for the ALLIANCE for Clinical Trials in Oncology, and Professor of Medicine, Division of Oncology, Section of Bone Marrow Transplantation at Washington University School of Medicine in St. Louis; Kevin Lin, MD, PhD Student, Developmental, Regenerative, and Stem Cell Biology Program at the Washington University in St. Louis; and Tae Kon Kim, MD, PhD, Assistant Professor of Medicine, Division of Hematology and Oncology at Vanderbilt University Medical Center.

Highlights from the Company’s mini-symposium on TBS-2025. The Company’s studies and data have shown the following:

VISTA was shown to be the only checkpoint highly upregulated in patients with AML with the highest expression in poor-risk subtypes. Its expression is seen in AML with or without common mutations like DNMT3A, NPM1, FLT-3.

VISTA expression on AML contributes to low response rate and short duration of response among patients with NPM1 mutated AML treated with menin inhibitors.

TBS-2025 provided survival advantage comparable to standard front line combination chemotherapy while significantly improving survival when used in combination with front line chemotherapy in murine model of VISTA expressing AML

Inhibition of VISTA, either through gene silencing or an inhibiting antibody, and inhibition of menin signaling pathway significantly improves survival in murine models of AML

"We are very pleased to announce that we have achieved the target enrollment to enable potential full approval filing in our Phase 2/3 registration-enabling trial of darovasertib in combination with crizotinib in first-line HLA*A2-negative metastatic uveal melanoma. This milestone reflects both the clear unmet need in metastatic uveal melanoma, as well as the strong clinical interest in our darovasertib program. Moreover, the promising overall survival data and broader clinical efficacy demonstrated in the recently reported median overall survival results from the Phase 1/2 clinical trial (OptimUM-01) of this combination in metastatic uveal melanoma are indicative of the clinical potential of darovasertib to meaningfully impact patients with this devastating disease. With target full enrollment now complete, we look forward to the availability of median PFS data we project from OptimUM-02 in the first quarter of next year, and, if approved, making darovasertib in combination with crizotinib available to patients with HLA*A2-negative metastatic uveal melanoma as a first-line treatment as expeditiously as possible," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.

OptimUM-02 is a multi-arm, multi-stage, open-label Phase 2/3 trial with patients randomized to receive either the darovasertib and crizotinib combination or investigator’s choice of treatment (pembrolizumab, ipilimumab + nivolumab, or dacarbazine). The primary endpoints are median PFS and median OS, which will be used to support a potential accelerated approval and full approval in the United States, respectively. In October 2025, IDEAYA presented data from its single-arm, Phase 2 trial (OptimUM-01) of the darovasertib and crizotinib combination at the Society for Melanoma Research (SMR) Congress that demonstrated a 21.1 month median OS and 7.0 months median PFS in 1L mUM, including both HLA*A2-negative and HLA*A2-positive patients.

Darovasertib has received U.S. Food and Drug Administration (FDA) Breakthrough Therapy Designation as neoadjuvant therapy in enucleation recommended primary uveal melanoma (UM) and Fast Track designation for darovasertib in combination with crizotinib in adult patients with metastatic UM. Darovasertib has also been designated as an Orphan Drug by the U.S. FDA in UM, including in metastatic UM. IDEAYA is currently enrolling patients in a pivotal Phase 3 trial of single-agent darovasertib in the neoadjuvant setting of primary UM (OptimUM-10).
