Press release

HĆørsholm, Denmark (26 October 2020) ā€“ Allarity Therapeutics A/S (ā€œAllarityā€ or the ā€œCompanyā€) today announced that the United States Patent and Trademark Office (USPTO) has issued Notices of Allowance to the Company for three new DRPĀ® biomarker patents in conjunction with use of several of its clinical pipeline drugs.

The USPTO has issued Notices of Allowance to the Company on the following three patent applications:

  • U.S. Patent Application No.: 16/444,881, ā€œMETHODS FOR PREDICTING DRUG RESPONSIVENESS IN CANCER PATIENTSā€ ā€“ Directed to a DRPĀ® biomarker for the Companyā€™s cancer drug Dovitinib, which biomarker is in development by Company as a companion diagnostic to select high likely responders for Dovitinib.

  • U.S. Patent Application No.: 15/858,703, ā€œMETHODS FOR PREDICTING DRUG RESPONSIVENESS IN CANCER PATIENTSā€ ā€“ Directed to a DRPĀ® biomarker for Cisplatin, including the Companyā€™s cancer drug LiPlaCisĀ®, which biomarker is in development by Company as a companion diagnostic to select high likely responders for LiPlaCisĀ®.

  • U.S. Patent Application No.: 15/978,655, ā€œMETHODS FOR PREDICTING DRUG RESPONSIVENESS IN CANCER PATIENTSā€ ā€“ Directed to DRPĀ® biomarkers for anthracyclines, including doxorubicin, epirubicin, and the Companyā€™s cancer drug 2X-111, which biomarker is in partnered development by Smerud Medical Research International as a companion diagnostic to select high likely responders for 2X-111.

The allowance and imminent issuance of these three new DRPĀ® biomarker patents further expands Allarityā€™s patent portfolio on unique, drug-specific DRPĀ® biomarkers developed with its best-in-class and highly validated DRPĀ® platform technology. The Company has now gained allowance and/or issuance of patents on more than 60 different DRPĀ® biomarkers.

Dovitinib, originally developed by Novartis, addresses a significant unmet need for improved therapies for the treatment of renal cell carcinoma and is a potential therapeutic alternative to sorafenib. Allarity is currently preparing to file its first new drug application (NDA) with the U.S. Food and Drug Administration (FDA) for approval of dovitinib as a treatment for renal cell carcinoma (RCC), using its Dovitinib DRPĀ® as a companion diagnostic to select and treat high likely responder patients. Dovitinib also has promising potential as a monotherapy in a number of other indications, including metastatic estrogen receptor (ER) positive breast cancer, hepatocellular cancer, endometrial cancer and gastrointestinal stromal tumors, as well as in combination therapy with other approved drugs, including immune checkpoint inhibitors.

LiPlaCisĀ® is an advanced, targeted liposomal formulation of cisplatin, one of the worldā€™s most widely used chemotherapies, being developed in partnership with Smerud Medical Research International AS for the treatment of metastatic breast cancer, using the Cisplatin DRPĀ® as a companion diagnostic to select and treat high likely responder patients. The specific LiPlaCisĀ® formulation allows delivery of the drug directly at tumor site, thereby increasing drug targeting at the tumor and reducing negative, off-target drug effects. LiPlaCisĀ® has previously shown promising results in a Phase 2 study in DRPĀ®-selected patients with late-stage metastatic breast cancer (mBC). In August 2019, the U.S. FDA approved an investigational device exemption (IDE) application for use of the Companyā€™s LiPlaCisĀ® DRPĀ® companion diagnostic in a planned pivotal Phase 3 study in mBC.

2X-111 is an advanced, targeted liposomal formulation of doxorubicin, one of the worldā€™s most widely used chemotherapies, being developed in partnership with Smerud Medical Research International AS for the treatment of glioblastoma multiforme (GBM), using the Doxorubicin DRPĀ® as a companion diagnostic to select and treat high likely responder patients. The specific 2X-111 formulation allows delivery of the drug across the blood-brain barrier (BBB) directly at the brain tumor site, thereby increasing drug targeting at the tumor and reducing negative, off-target drug effects. 2X-111 has previously shown promising results in a Phase 2 study in both GBM patients and patients with brain metastases of breast cancer.

Steve Carchedi, CEO of the Company, noted ā€œWe see the allowance of these patents from the USPTO as further validation of the inventive importance of our core DRPĀ® platform and its resulting, drug-specific companion diagnostics, which we believe will help bring the promise of personalized medicine to cancer patients. The issuance of these new patents on our dovitinib, LiPlaCisĀ®, and 2X-111 programs solidifies our competitive advantage as we advance these promising cancer therapeutics to the market and to patients, and underscores our global leadership in the development and use of best-in-class companion diagnostics that are designed to match the right cancer patient to the right drug.ā€

Steen Knudsen, Ph.D., CSO and Co-Founder of the Company, further stated, ā€œI am pleased to see the USPTOā€™s recognition of these three novel and valuable DRPĀ® biomarkers, through allowance of these patents, as Allarity continues to develop and utilize such DRPĀ® biomarkers as companion diagnostics to advance our therapeutic pipeline, including dovitinib, LiPlaCisĀ®, and 2X-111 towards approval and to improve treatment options for cancer patients.ā€

About the Drug Response Predictor ā€“ DRPĀ® Companion Diagnostic

Allarity uses its drug specific DRPĀ® to select those patients who, by the genetic signature of their cancer, are found to have a high likelihood of responding to the specific drug. By screening patients before treatment, the response rate can be significantly increased. The DRPĀ® method builds on the comparison of sensitive vs. resistant human cancer cell lines, including genomic information from cell lines combined with clinical tumor biology and prior clinical trial outcomes. DRPĀ® is based on messenger RNA from the patientā€™s biopsies. DRPĀ® has proven its ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients in nearly 40 clinical studies that were examined, including an ongoing, prospective Phase 2 trial. The DRPĀ® platform can be used in all cancer types and is patented for more than 70 anti-cancer drugs.

About Allarity Therapeutics
Allarity Therapeutics (Nasdaq First North Growth Market Stockholm: ALLR.ST) develops drugs for personalized treatment of cancer guided by its proprietary drug response predictor technology, the DRPĀ® platform.
