Boston (November 18, 2024)—Allarity Therapeutics, Inc. ("Allarity" or the "Company") (NASDAQ: ALLR), a Phase 2 clinical-stage pharmaceutical company dedicated to developing personalized cancer treatments using its proprietary, drug-specific patient selection technology, today provided a corporate update highlighting three significant developments: extended treatment duration for patients in its ongoing Phase 2 stenoparib trial, a strengthened cash position supporting initiation of a follow-up FDA registrational trial, and new revenue-generating activities from Allarity's laboratory services.

Key Progress in Phase 2 Stenoparib Trial
Two patients in Allarity's Phase 2 clinical trial of stenoparib for advanced, recurrent ovarian cancer have now been on treatment for over 14 months, a remarkable duration of benefit given the heavily pretreated status of these patients. This extended duration further reinforces the potential of stenoparib as a promising treatment option for advanced ovarian cancer patients who have already undergone multiple lines of therapy, including prior PARP inhibitors.

Strong Financial Position Supports Advancement of Stenoparib Program
With a cash balance of $18.5 million as of September 30, 2024, Allarity Therapeutics is well-positioned to advance its clinical development programs. This solid financial foundation enables the Company to confidently initiate the next trial to advance stenoparib toward FDA registration.

Allarity Expands into Revenue-Generating Services for External Clients
Allarity Therapeutics is also pleased to announce that its in-house Allarity Medical Laboratory has expanded from solely focusing on supporting internal drug development to securing external service agreements, with multiple biotech companies now leveraging the Company's advanced gene expression and diagnostic capabilities. This important expansion positions Allarity Medical Laboratory as a direct provider of revenue-generating, high-precision genomic services, establishing it as a valuable complementary asset for the Company.

These service agreements include contracts for both Drug Response Predictor (DRP) analysis and comprehensive gene expression services, reflecting Allarity's leading technology and ability to provide industry-leading insights to other innovators in the biotech field. The revenue generated from such agreements significantly reduce Allarity's overall laboratory cost base while advancing the position of Allarity's proprietary DRP platform within the industry and supporting broader scientific advancements in oncology.

Thomas Jensen, CEO of Allarity Therapeutics, commented, "Seeing patients continue to benefit from stenoparib beyond 14 months is very encouraging for us at Allarity, as it goes beyond our initial hopes when we began the trial. We are pleased to see the lasting clinical benefit in these very advanced patients and think this reflects stenoparib's unique therapeutic mechanism of action. We are excited that our strengthened cash position now provides the financial foundation to accelerate stenoparib's clinical development toward FDA approval"

He added, "I am also excited about our successful seamless expansion into the service provider space. Over the years, our lab team has developed deep expertise in advanced genetic analysis to support cancer drug development, and naturally leveraging this to build a revenue-generating analytics department is extremely satisfying. In addition to generating meaningful revenue, this expansion further establishes our company, our brand and the DRP platform within the oncology field."

Background Information about the Trial
The above-mentioned trial is a Phase 2, prospective open-label, single-arm study with multiple sites in both the US and the UK. Investigators prescreened women with advanced, recurrent ovarian cancer using Allarity's DRP companion diagnostic (CDx), which comprises a complex transcriptomic signature of 414 mRNA biomarkers indicative of drug response or resistance. Each participant was assigned a DRP score, and those with scores above 50 -suggesting a higher likelihood of benefiting from treatment – were selected to receive stenoparib. The selected patients were administered stenoparib under a revised protocol implemented in Q1 2023, which involved a twice-daily dosing regimen (200 mg in the morning and 400 mg in the evening) instead of the previous once-daily 600 mg dose. This change was made to optimize daily drug exposure and target inhibition.

The patients enrolled have advanced through multiple lines of therapy, including platinum, taxanes, anti-angiogenesis inhibitors, and even the recently approved Antibody Drug Conjugate, Elahere. Importantly, most of the enrolled patients to date have been previously treated with a PARP inhibitor. These patients have few, if any, effective treatment options and typically advance through available therapies after only a few months.
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. Allarity has 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, are found to 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 significantly increased. 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 proven its ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients dozens of clinical studies (both retrospective and prospective). The DRP platform, which can be used in all cancer types and is patented for more than 70 anti-cancer drugs, has been extensively published in the peer-reviewed literature.
