Predictive Oncology Develops Novel Approach to Identifying Clinically Viable Abandoned Drugs

New indications discovered by applying active machine learning and using samples from the company's vast biobank of live-cell tumors specimens

Builds upon Predictive's biomarker discovery platform to select targeted patient cohorts to significantly de-risk clinical trials

PITTSBURGH, April 15, 2025 (GLOBE NEWSWIRE) -- Predictive Oncology Inc. (NASDAQ:POAI), a leader in AI-driven drug discovery, announced today that it has made significant progress along the continuum of biomarker discovery, drug discovery and drug repurposing. These latest developments build upon Predictive's ongoing initiative to combine its in-house biomarker identification platform with its AI screening capabilities.

Identifying new indications using active machine learning and a biobank of patient derived dissociated tumor cells (DTCs) represents a novel and commercially sustainable approach to repurposing abandoned oncology drugs.

"This efficient screening approach on a small, curated cohort of abandoned drugs identified three compounds that warrant further exploration in tumor indications that have never been examined in this way," said Dr. Arlette Uihlein, SVP of Translational Medicine and Drug Discovery and Medical Director at Predictive Oncology. "The work that we have done successfully demonstrates our ability to utilize our active machine learning and biobank of tumor samples to capture patient response heterogeneity in less than 12 weeks."

The results of Predictive's novel approach to identifying clinically viable abandoned drugs are compelling.

Three drugs gave strong results for both ovarian and colon tumors. Specifically, Afuresertib, Alisertib and Entinosta demonstrated the highest proportion of hits within those two tumor types. Notably, Alisertib and Entinostat outperformed Oxaliplatin, a standard of care drug in the colon tumor type, while Alisertib also outperformed Ribociclib, a standard of care in breast cancer.

Afuresertib, is an Akt inhibitor that was previously studied in esophageal cancer, multiple myeloma, and more recently, attempted in combination with paclitaxel in platinum resistant ovarian cancer.

Alisertib, a selective Aurora A Inhibitor previously studied for use in both EGFR-mutated non-small cell lung cancer (NSCLC) and metastatic breast cancer, showed strong tumor drug response in ovarian and colon tumors based on both Predictive's wet lab testing and AI models. This drug is currently being evaluated in clinical trials for recurrent/metastatic breast cancer and lung cancer.

Entinostat, an HDAC1/3 inhibitor which was previously studied in solid tumor types, including breast and pancreatic, had a strong tumor drug response in the company's colon sample models. This drug is currently in clinical trials for use as a combination therapy in patients with NSCLC and for the purpose of biomarker development.

Of particular significance to Predictive Oncology, this drug class was previously shown to induce mitochondrial dysfunction in colorectal cancer, which is a possible target for further exploration combining the company's high content imaging (HCI) assay and its proprietary and internally derived HCI analysis pipeline.

"Applying this approach to other sets of publicly available abandoned drugs is a next logical step," said Raymond Vennare, CEO of Predictive Oncology. "But, more importantly, from the perspective of partnering opportunities with pharmaceutical companies to retain or repurpose their own abandoned drugs, our methodology would be advantageous in terms of efficiently transitioning their abandoned drugs back to clinical trial readiness."

About Predictive Oncology

Predictive Oncology is on the cutting edge of the rapidly growing use of artificial intelligence and machine learning to expedite early drug discovery and enable drug development for the benefit of cancer patients worldwide. The company's scientifically validated AI platform, PEDAL, is able to predict with 92% accuracy if a tumor sample will respond to a certain drug compound, allowing for a more informed selection of drug/tumor type combinations for subsequent in-vitro testing. Together with the company's vast biobank of more than 150,000 assay-capable heterogenous human tumor samples, Predictive Oncology offers its academic and industry partners one of the industry's broadest AI-based drug discovery solutions, further complimented by its wholly owned CLIA laboratory facility. Predictive Oncology is headquartered in Pittsburgh, PA.
