Moreover, based on insights from our ongoing stenoparib clinical development, we believe our DRP\u00ae platform may play an important role in identifying those patients most likely to achieve the outcomes we ultimately seek in cancer therapy: enhanced and extended survival with a favorable tolerability profile. It is difficult to overstate the importance of this, as extended survival- especially from an easy-to-take oral therapy without the typical toxicities of chemotherapy- addresses the most critical considerations for both patients and oncologists when selecting a particular therapy.\u201d<\/p>\n<p>Both posters are available on the Company\u2019s website under the Scientific Publications section.<\/p>\n<p>\n        <b>About Stenoparib\/2X-121<\/b><br \/>\n        <br \/>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\/\u03b2-catenin signaling has been implicated in the development and progression of numerous cancers. By inhibiting PARP and blocking WNT pathway activation, stenoparib\u2019s 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 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 designed to accelerate the clinical development of stenoparib toward FDA approval. 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.<\/p>\n<p><b>About the Drug Response Predictor \u2013 DRP<\/b><sup><b>\u00ae<\/b><\/sup><b> Companion Diagnostic<\/b><br \/>Allarity uses its drug-specific DRP<sup>\u00ae<\/sup>\u00a0to 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<sup>\u00ae<\/sup>\u00a0platform 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.<\/p>\n<p><b>About Allarity Therapeutics<\/b><br \/>Allarity Therapeutics, Inc.
