"Reaching full enrollment in this trial is a critical step toward our goal of establishing OJEMDA as standard of care across all lines of therapy for individuals with BRAF-altered pLGG. By moving earlier in the treatment journey, we aim to intervene when we can have the greatest impact on the burden of this challenging cancer," said Elly Barry, M.D., Chief Medical Officer at Day One, now part of Servier Group. "Success in this study would not only further validate the efficacy and safety profile of OJEMDA, but also fundamentally evolve the pLGG treatment paradigm, and potentially establish a new standard of care for patients newly diagnosed with pLGG, the most common brain tumor afflicting children."

FIREFLY-2 is a Phase 3, global, randomized, multicenter, open-label study to evaluate the efficacy, safety, and tolerability of monotherapy tovorafenib, an oral, Type II RAF inhibitor, in patients ages 6 months to 25 years with RAF-altered pLGG requiring first-line systemic therapy. It is being conducted at approximately 140 sites across the U.S., Canada, Europe, Australia, South America, Middle East and Asia, and in just over three years has enrolled approximately 400 participants who are receiving either tovorafenib once weekly or one of four standard of care (SoC) chemotherapy regimens.

"Completing enrollment in FIREFLY-2 is a powerful early signal of momentum. It reflects what’s possible when we bring together deep scientific expertise, a patient-first culture, and the scale to execute globally," said David K. Lee, CEO of Servier Pharmaceuticals. "So soon after Servier’s acquisition of Day One, this milestone reinforces our conviction that joining forces was the right decision for patients and for our oncology strategy. As we aim to accelerate the development of targeted medicines and advance them with the rigor, speed and reach needed to make a meaningful difference, we hope this study helps unlock the potential to improve outcomes for children living with pediatric low-grade glioma."

The primary endpoint of the trial is overall response rate (ORR), including duration of response (DOR), based upon Response Assessment in Pediatric Neuro-Oncology Low-Grade Glioma (RAPNO-LGG) criteria, with key secondary endpoints including progression-free survival (PFS) and event-free survival (EFS) per RAPNO-LGG, time to next treatment (TTNT), overall survival (OS) and other measures, including patient-reported outcomes. The primary analysis is expected to occur approximately 12 months after the last patient is enrolled; preliminary insights are expected to be available in 2027.

About tovorafenib
Tovorafenib (known as OJEMDATM in the U.S.) is a Type II RAF kinase inhibitor of mutant BRAF V600, wild-type BRAF, and wild-type CRAF kinases. Tovorafenib is indicated for the treatment of patients 6 months of age and older with relapsed or refractory pediatric low-grade glioma (LGG) harboring a BRAF fusion or rearrangement, or BRAF V600 mutation. This indication is approved under accelerated approval based, in part, on response rate and duration of response according to multiple response assessment criteria: Response Assessment in Neuro-Oncology High-Grade Glioma (RANO-HGG) criteria, Response Assessment in Pediatric Neuro-Oncology Low-Grade Glioma (RAPNO LGG) criteria, and Response Assessment for Neuro-Oncology Low-Grade Glioma (RANO LGG) criteria. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

Tovorafenib was granted Breakthrough Therapy and Rare Pediatric Disease designations by the FDA for the treatment of patients with pLGG harboring an activating RAF alteration, and it was evaluated by the FDA under priority review. Tovorafenib has also received Orphan Drug designation from the FDA for the treatment of malignant glioma and from the European Commission for the treatment of glioma.

About Pediatric Low-Grade Glioma
Pediatric low-grade gliomas (pLGG) are the most common brain tumor with an estimated US incidence of 1,100 and Europe incidence of 700 children per year who are eligible for front-line systemic therapy.i, ii BRAF is the gene most commonly altered in pLGG, which includes two primary types of BRAF alterations – a BRAF gene fusion and BRAF point mutation. These BRAF alterations account for >50% of pLGG cases worldwide and prior to the introduction of OJEMDA, there were no approved treatments for people with pLGG driven by BRAF fusions.i, iii

Pediatric low-grade gliomas can be chronic and relentless, with patients suffering profound side effects from both the tumor and the treatment, which may include chemotherapy and radiation. These side effects can impact their life over the long term, and may include motor deficiencies, vision loss, hormone deficiency and alterations in growth and development. Most children with pLGG will survive their cancer, but for the majority of those in whom a complete surgical resection is not possible, these tumors tend to recur frequently throughout childhood, necessitating multiple treatments. The cumulative toxicity of numerous therapies, along with the damage caused by multiple episodes of tumor progression, take a significant toll on the children and their families.

NUT carcinoma is a rare, poorly differentiated carcinoma characterized by NUTM1 gene rearrangement. The disease progresses rapidly, with a median survival of only approximately 6.5 months. It commonly occurs in the lungs, head, and neck regions, and the median age of onset is only 23.6 years. Due to the lack of specificity in clinical manifestations and insufficient awareness among the public, the rates of misdiagnosis and missed diagnosis are extremely high, and most patients are already at an advanced stage at the time of diagnosis. Currently, no effective targeted drug for NUT carcinoma has been approved globally, and the treatment landscape is extremely dire.

The granting of Breakthrough Therapy Designation to NHWD-870 HCI is primarily based on the significant efficacy and survival benefits demonstrated in its Phase II clinical study. As of December 27, 2025, a total of 40 evaluable subjects with advanced NUT carcinoma were enrolled in the study. The data showed that the drug exhibited positive anti-tumor activity across different lesion sites: the objective response rate (ORR) in 20 patients with advanced thoracic NUT carcinoma reached as high as 45.00%; the median overall survival (mOS) for advanced thoracic NUT carcinoma patients and for all subjects both reached 9.33 months, representing a significant extension compared with standard chemotherapy regimens. Currently, some patients are still receiving ongoing treatment and close follow-up. In addition, preliminary safety data showed that the drug was generally well tolerated and held high potential for clinical application.

This Breakthrough Therapy Designation is of great significance for NUT carcinoma patients and represents a leapfrog advance in the field. For patients, it means that the regulatory review process for NHWD-870 HCI will be accelerated and the drug will reach the market sooner, enabling patients with advanced NUT carcinoma to receive targeted therapy earlier and escape the dilemma of having no effective drug, thereby significantly prolonging survival and improving quality of life. On the clinical level, the development and designation of this drug fill the gap in targeted treatment for NUT carcinoma and provide clinicians with a completely new treatment option. This not only drives the transformation of NUT carcinoma treatment from "symptomatic treatment" to "precision targeted therapy" but also provides valuable clinical experience for the future development of similar drugs.

Mr. Nenghui Wang, Founder of Wenda Pharma, stated: "We are delighted that our product has received Breakthrough Therapy Designation. This progress highlights China’s growing capabilities in innovative drug development for rare cancers. NHWD-870 not only brings hope to NUT carcinoma patients but also offers new avenues for exploring treatments for other rare malignancies."

Professor YIN Mingzhu, Director of the Midline (NUT) Carcinoma Specialty at the Affiliated Three Gorges Hospital of Chongqing University, noted, "NUT carcinoma once plunged countless patients and doctors into despair. The Breakthrough Therapy Designation for NHWD-870 is an important achievement integrating medical research and clinical practice. In the future, with the accelerated market entry of this drug, the treatment landscape of NUT carcinoma is expected to be completely transformed, injecting new momentum into the cause of rare disease diagnosis and treatment in our country."

Presentation Details:

Event: Precision Medicine Forum Europe 2026
Presentation Title: Dual Inhibition of PARP and WNT: A Novel Drug-Biomarker Combination in Clinical Trials
Track: Oncology
Date: Monday, May 11, 2026
Time: 10:20–10:40 CEST

Mr. Jensen will discuss stenoparib’s dual mechanism of action and Allarity’s predictive biomarker, the Stenoparib DRP, based on a 414-mRNA gene expression signature, which is designed to identify patients who may be more likely to benefit from stenoparib, as well as the Company’s ongoing Phase 2 trials.

Mr. Jensen will be available for individual meetings during the conference to discuss Allarity’s clinical development strategy and potential business development opportunities.

About Stenoparib/2X-121
Stenoparib is an orally available, small-molecule dual-targeted inhibitor of PARP1/2 and tankyrase 1/2. At present, tankyrases are attracting significant attention as emerging therapeutic targets for cancer, principally due to their role in regulating the WNT signaling pathway. Aberrant WNT/β-catenin signaling has been implicated in the development and progression of numerous cancers. By inhibiting PARP and blocking WNT pathway activation, stenoparib’s unique therapeutic action shows potential as a promising therapeutic for many cancer types, including ovarian cancer, Small Cell Lung Cancer and colorectal cancer. Allarity has secured exclusive global rights for the development and commercialization of stenoparib, which was originally developed by Eisai Co. Ltd. and was formerly known under the names E7449 and 2X-121. Allarity has two ongoing Phase 2 trial protocols for stenoparib in Ovarian Cancer patients. In the first, patients who had had 2+ lines of therapy were enrolled on stenoparib and given drug twice daily. This protocol has been closed to further enrollment but continues for the enrolled patients who are still receiving benefit from stenoparib administration. The updated data from this study were presented at the AACR (Free AACR Whitepaper) special conference on advances in Ovarian Cancer in September 2025. Note that, as these data are from an ongoing trial, analyses may change as the study fully matures. An amended protocol designed expressly to capitalize on the emerging clinical experience with stenoparib in platinum resistant patients began enrolling patients in the summer of 2025. This amended protocol enrolls only platinum resistant or platinum-ineligible patients and is intended to support future pivotal development and eventual regulatory review. In parallel, a separate Phase 2 trial evaluating stenoparib in combination with temozolomide for relapsed small cell lung cancer (SCLC) began enrolling patients in early 2026 and is currently enrolling patients across multiple U.S. Veterans Administration (VA) sites.

About the Drug Response Predictor – DRP Companion Diagnostic
Allarity uses its drug-specific DRP to select those patients who, by the gene expression signature of their cancer, may have a high likelihood of benefiting from a specific drug. By screening patients before treatment, and only treating those patients with a sufficiently high, drug-specific DRP score, the therapeutic benefit rate may be enhanced. The DRP method builds on the comparison of sensitive vs. resistant human cancer cell lines, including transcriptomic information from cell lines, combined with clinical tumor biology filters and prior clinical trial outcomes. DRP is based on messenger RNA expression profiles from patient biopsies. The DRP platform has shown an ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients across dozens of clinical studies (both retrospective and prospective). The DRP platform, which may be useful in all cancer types and is patented for dozens of anti-cancer drugs, has been extensively published in the peer-reviewed literature.

"This oral plenary session, which reviewed data collected to date, and included an overview of the ReSPECT-LM single dose escalation study, is an important validation of the clinical and translational evidence supporting REYOBIQ as a differentiated therapeutic approach for patients with leptomeningeal metastases, a devastating condition with no FDA-approved therapies. AANS is an important congress, and we are encouraged by these data being featured in such a prominent part of the conference," said Eric J. Daniels, M.D., M.B.A., Plus Therapeutics Chief Development Officer. "We continue to believe strongly in the potential of REYOBIQ in the clinical setting as we continue the ongoing multiple dose trial."

The oral presentation, titled, "¹⁸⁶Rhenium-Nanoliposomes (¹⁸⁶RNL) for the Treatment of Leptomeningeal Metastases: Translational Insights from Clinical and Preclinical Models," was delivered by Henriette U. Balinda, PhD, of UT Health San Antonio in a Plenary Session on Saturday, May 2, 2026.

Key Data Highlights

The Presentation highlighted the completed Phase 1 ReSPECT-LM study demonstrating:

Encouraging survival outcomes, with median overall survival of approximately 9 months in patients treated at the recommended Phase 2 dose, compared to historical survival of approximately 2–6 months
Robust anti-tumor activity, including high rates of circulating tumor cell (CTC) reduction and clinical benefit across evaluable patients
Favorable safety and tolerability profile, supporting advancement into later-stage clinical development
Highly targeted radiation delivery, with a target-to-off-target absorbed dose ratio exceeding 100:1, minimizing exposure to healthy tissue
In addition, translational analyses presented in the session demonstrate that REYOBIQ may induce immune remodeling within the tumor microenvironment, including activation of CD8+ T cells and enhancement of anti-tumor immune response, supporting potential future combination strategies with immunotherapies.

Currently, the ReSPECT-LM Phase 1 Multiple Dose trial is underway and enrolling patients at the University of Texas Health San Antonio. The primary objectives include characterizing safety and tolerability of multiple doses at defined intervals of REYOBIQ for patients of any primary solid tumor cancer with LM.

About REYOBIQ (rhenium Re186 obisbemeda)

REYOBIQ (rhenium Re186 obisbemeda) is a novel injectable radiotherapy specifically formulated to deliver direct targeted high dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. REYOBIQ has the potential to reduce off-target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. REYOBIQ is being evaluated for the treatment of recurrent glioblastoma, leptomeningeal metastases, and pediatric brain cancer in the ReSPECT-GBM, ReSPECT-LM, and ReSPECT-PBC clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6M grant by the Cancer Prevention & Research Institute of Texas (CPRIT). The Company’s ReSPECT-PBC clinical trial for pediatric brain cancer is supported by a $3 million grant from the U.S. Department of Defense’s Peer Reviewed Cancer Research Program.
