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.

"We remain disappointed with the unanticipated outcome of the FLASH2 (Fluorescent Light Activated Synthetic Hypericin 2) study," stated Christopher J. Schaber, PhD, President and Chief Executive Officer of Soligenix. "Despite the fact that HyBryte (synthetic hypericin) demonstrated statistically significant reductions in cutaneous T-cell lymphoma (CTCL) lesions after 6 weeks treatment in the first FLASH study, a similar signal was not observed with 18 weeks of treatment in this study. Over the coming weeks, we will analyze the data to better determine why the study did not meet expectations. If there is any clarity gained from further analysis of the dataset, especially with respect to specific subsets of patients that may benefit from HyBryte therapy, then we intend to communicate our findings and explore follow-up discussions with the European Medicines Agency (EMA) and the Food and Drug Administration (FDA)."

With approximately $6.0 million in cash at March 31, 2026, and cash runway into the 2nd quarter of 2027, we will evaluate all strategic options moving forward, including but not limited to merger and acquisition opportunities, and the potential of advancing SGX945 (dusquetide) for the treatment of Behçet’s Disease, which demonstrated promising biological efficacy in a Phase 2 study last year while most recently receiving orphan drug designation from EMA and Promising Innovative Medicine (PIM) designation from the United Kingdom Medicines and Healthcare Products Regulatory Agency (MHRA). In December, we announced the extended results of the Phase 2a trial of SGX302 (synthetic hypericin) for the treatment of mild-to-moderate psoriasis where SGX302 gel therapy was well tolerated by all patients with no drug related adverse events identified. With the completion of the pilot study, we have laid the groundwork for a more detailed evaluation in this large underserved market.

Financial Results – Quarter Ended March 30, 2026

Soligenix had no revenue or related costs for the quarter ended March 31, 2026 and 2025, respectively.

Soligenix’s net loss was $2.8 million, or ($0.28) per share, for the quarter ended March 31, 2026, compared to $3.0 million, or ($0.97) per share, for the same prior year period. This decrease in net loss was primarily due to a decrease in operating expenses.

Research and development expenses were $1.8 million as compared to $1.9 million for the quarter ended March 31, 2026 and 2025, respectively. The decrease was primarily due to decreases in costs associated with third-party manufacturing, the completed Phase 2 study in BD and site initiation fees for the second confirmatory Phase 3 CTCL trial, partially offset by an increase in patient fees for the second confirmatory Phase 3 CTCL trial.

General and administrative expenses were $1.1 million for the quarter ended March 31, 2026 as compared to $1.1 million for the same period in 2025, relatively flat with a de minimis increase.

As of March 31, 2026, the Company’s cash position was approximately $6.0 million.
