TARPON SPRINGS, Fla., November 14, 2025 – Allarity Therapeutics, Inc. (“Allarity” or the “Company”) (NASDAQ: ALLR), a Phase 2 clinical-stage pharmaceutical company dedicated to developing stenoparib (2X-121)—a differentiated, dual PARP and WNT pathway inhibitor—today reported financial results and provided an update on operational highlights for the third quarter ended September 30, 2025.

“The third quarter of 2025 was another milestone period for Allarity as we achieved FDA Fast Track designation for stenoparib in advanced ovarian cancer—an important acknowledgment of the potential of our lead program. We also reported new clinical data showing median overall survival now exceeding 25 months for patients in our Phase 2 trial—a remarkable finding in this difficult-to-treat population. Alongside these achievements, we continued to advance our DRP platform commercially through a new licensing and laboratory services agreement,” said Thomas Jensen, CEO of Allarity Therapeutics. “The consistency of our progress reflects our disciplined, focused strategy and execution. Stenoparib continues to show durable clinical benefit in women with advanced, platinum resistant ovarian cancer, and we continue to deepen our understanding of its unique dual mechanism of action through our collaboration with the Indiana Biosciences Research Institute. With both the ongoing ovarian cancer trial progressing under Fast Track designation and the forthcoming U.S. Veterans Administration–funded small cell lung cancer combination study advancing toward initiation, we see the potential to broaden stenoparib’s therapeutic reach—offering new hope for patients across multiple hard-to-treat cancer types.”

Clinical and Drug Development Progress

FDA Fast Track designation: In August 2025, the U.S. Food and Drug Administration granted Fast Track designation to stenoparib for the treatment of advanced ovarian cancer, recognizing the significant unmet medical need in this patient population. The designation enables more frequent interactions with the FDA and potential eligibility for accelerated and priority review pathways.

Landmark survival data: In September 2025, at the AACR 7th Biennial Special Conference on Ovarian Cancer, Allarity presented new Phase 2 data showing that median overall survival for patients receiving twice-daily stenoparib has not yet been reached and now exceeds 25 months.

Ongoing trial enrollment: Enrollment continued in the new Phase 2 trial protocol evaluating stenoparib in recurrent, platinum-resistant or platinum-ineligible advanced ovarian cancer. The study has maintained steady investigator engagement and is expected to generate critical data by end of 2026.

IBRI research collaboration: Work with the Indiana Biosciences Research Institute (IBRI) remains on track, with molecular and cellular studies underway to clarify the individual and combined contributions of PARP inhibition and WNT pathway modulation to stenoparib’s anticancer activity. This research aims to deepen the Company’s mechanistic understanding of the molecule and support future development opportunities in ovarian cancers as well as other cancers such as Small Cell Lung Cancer and potentially Colorectal Cancer.

Corporate and Strategic Developments

DRP^® platform expansion: Signed a new commercial agreement with an EU-based biotechnology company providing a non-exclusive global license to selected breast cancer DRP algorithms and securing laboratory service commitments through the Allarity Medical Laboratory in Denmark.

Scientific visibility and partnering: In October 2025, CEO Thomas Jensen presented at Biomarkers & Precision Medicine 2025 in London, highlighting the role of the stenoparib DRP® companion diagnostic in optimizing patient selection and advancing precision oncology. Earlier in the third quarter, new survival data from the ongoing ovarian cancer trial were also presented at the AACR 7th Biennial Special Conference on Ovarian Cancer—a premier scientific forum hosted by the American Association for Cancer Research.

Financial position: Ended the third quarter with a solid cash position, consistent with prior guidance, maintaining a financial runway through Q4 2026.

Anticipated Clinical Milestones in 2025–2026

Ovarian cancer trial progress: Continued extension of median Overall Survival in the first Ovarian cancer trial using twice daily dosing. Fast-paced enrollment in the new protocol in platinum resistant or ineligible ovarian cancer patients.

SCLC combination trial launch: U.S. Veterans Administration–funded Phase 2 trial of stenoparib plus temozolomide in recurrent small cell lung cancer expected to be open for enrollment by year-end 2025. This represents the first combination study for stenoparib and may demonstrate that the safety profile of stenoparib makes it an ideal drug for combination therapy.

Third Quarter 2025 Financial Highlights

Cash Position: As of September 30, 2025, Allarity finished the quarter with $16.9 million in cash, a decrease of $0.9 million since June 30, 2025. The Company continues to maintain a financial runway to December 2026.

R&D Expenses: Research and development expenses for the third quarter of 2025 were $1.2 million, compared to $1.0 million for the third quarter of 2024.

G&A Expenses: General and administrative expenses for the third quarter of 2025 were $1.3 million, compared to $1.6 million for the third quarter of 2024.

Net Loss: Net loss attributable to common stockholders for the third quarter of 2025 was $2.8 million, compared to a net loss of $12.2 million for the third quarter of 2024.

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 this AACR special conference on advances in Ovarian Cancer. 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 this summer. This amended protocol enrolls only platinum resistant or platinum-ineligible patients and is designed to accelerate the clinical development of stenoparib toward FDA approval.

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.
