Exhibit 99.1

Allarity Therapeutics Announces that

the Stenoparib DRP® Test Has Received a Notice of Allowance from the US Patent and Trademark Office

- Patent expected to

be formally granted within three months, subject to standard administrative procedures

- Patent would provide exclusivity at least

into 2039 for stenoparib when used in concert with the stenoparib DRP test

TARPON SPRINGS, Fla., April 27, 2026 – 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 announced that the United States

Patent and Trademark Office (USPTO) has issued a Notice of Allowance for its patent application covering the Company’s DRP®

companion diagnostic specific to stenoparib.

Importantly, this Notice of Allowance covers multiple claims and represents

a major step in Allarity’s global strategy to expand and protect the commercial potential of stenoparib when selecting patients

using its proprietary stenoparib DRP® test. The patent is expected to be formally granted within three months, subject

to standard administrative procedures and would provide exclusivity at least into 2039 for stenoparib when used in concert with the DRP®

as a companion diagnostic.

Thomas Jensen, CEO of Allarity Therapeutics, commented: “This

Notice of Allowance from the USPTO represents another successful milestone in our efforts to secure intellectual property protection for

our DRP® technology in the US, the world’s most important pharmaceutical market. Critically, this patent maximizes the marketing

exclusivity in the US for stenoparib in patients selected using the stenoparib DRP test, which is especially important as we seek to accelerate

stenoparib toward approval for Ovarian and other cancers.”

The allowed claims include methods for predicting clinical benefit

based on gene expression profiles derived from tumor samples and for selecting those patients most likely to benefit from stenoparib treatment.

Allarity previously secured a European and Australian patent for the

Stenoparib DRP® and holds 18 granted patents for other drug-specific DRPs, including eight in the United States. Patent

applications for the Stenoparib DRP® remain pending in Canada, Japan, China, and India.

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 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.

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.

About Allarity Therapeutics

Allarity Therapeutics, Inc. (NASDAQ: ALLR) is a clinical-stage biopharmaceutical

company dedicated to developing personalized cancer treatments. The Company is focused on development of stenoparib, a novel PARP/tankyrase

inhibitor for advanced ovarian cancer patients, using its DRP® technology to develop a companion diagnostic that can

be used to select those patients expected to derive the greatest clinical benefit from stenoparib. Allarity is headquartered in the U.S.,

with a research facility in Denmark, and is committed to addressing significant unmet medical needs in cancer treatment. For more information,
