Exhibit 99.1

Allarity Therapeutics Announces Changes to Board of Directors

TARPON SPRINGS, Fla., June 11, 2025 -- Allarity Therapeutics, Inc. (“Allarity” or the “Company”) (NASDAQ: ALLR), a Phase 2 clinical-stage pharmaceutical company dedicated to developing stenoparib—a differentiated, dual PARP and WNT pathway inhibitor—as a personalized cancer treatment using its proprietary, drug-specific Drug Response Predictor (DRP®) patient selection technology—today announced that Jesper Høiland has been appointed to join the Company’s Board of Directors. He will be replacing Joseph Vazzano, who will resign from the Board effective on June 30, 2025, following his valuable contributions to Allarity’s development over the past two years.

Mr. Høiland is already well-acquainted with Allarity’s mission and operations, having served as a strategic consultant to the Company since October 2024.

Jesper Høiland is a highly respected industry leader with more than 30 years of experience in global pharmaceutical commercialization and executive leadership. He previously served as President and EVP of Novo Nordisk’s U.S. operations, where he led major product launches, pricing strategies, and infrastructure expansion. In addition, he held senior executive roles as President and CEO of Radius Health and as Global Commercial Officer at Ascendis Pharma. Mr. Høiland currently serves as Chairman of SciBase Holding AB and is a board member of ALK-Abello A/S and Flen Health SA.

“We are pleased to welcome Jesper Høiland to the Allarity Board during a period of growing clinical momentum,” said Jerry McLaughlin, Chairman of the Board of Directors at Allarity Therapeutics. “On behalf of the entire Board, I would also like to thank Joseph Vazzano for his contributions to Allarity. His financial expertise and thoughtful guidance helped strengthen our governance and operational focus during a critical time. We are grateful for his service and wish him the very best in his ongoing endeavors.”

Thomas Jensen, CEO of Allarity Therapeutics, added: “Since Jesper started working with us in his consultancy capacity, I have several times benefited from his experience and strategic advice. His deep understanding of how to prepare for the commercialization phase of an investigational drug, his extensive global network—built over decades at Novo Nordisk—and his proven leadership during periods of strategic transition at Radius Health will certainly be valuable to Allarity. It is very positive that he will now be even more closely engaged with the Company, as we prepare for the next phases of clinical development and potential later commercialization of stenoparib.”

About Stenoparib
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. 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.

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.
