Predictive Oncology Study Demonstrates Long-Term Stability and Viability of Proprietary Biobank of Primary Tumor Specimens for Pharmaceutical Drug Discovery

Rhea-AI Summary

Predictive Oncology Inc. (NASDAQ: POAI) has announced successful study results demonstrating the long-term stability and viability of over 150,000 cryopreserved patient tumor samples in its proprietary biobank. The study showed 100% concordance in drug response results between original fresh patient sample testing and long-term cryogenically stored tumor material, some preserved for up to 16 years.

This validation is important for predicting patient outcomes, guiding personalized therapies, target validation, and in silico modeling of drug-tumor responses. The company's biobank, containing 150,000+ tumor specimens, 200,000+ pathology slides, and 20 years of actionable data, positions Predictive Oncology as a key player in AI-driven drug discovery. The global biospecimen market, valued at $4.4 billion in 2023, is expected to reach $11.7 billion by 2031, growing at a CAGR of over 13%.

Global biospecimen market valued at $4.4 billion in 2023, expected to grow at an annual CAGR of more than 13%, reaching $11.7 billion by 2031¹

PITTSBURGH, Aug. 27, 2024 (GLOBE NEWSWIRE) -- Predictive Oncology Inc. (NASDAQ: POAI), a leader in AI-driven drug discovery, today announced the results of a successful study that demonstrates the long-term stability and viability of the more than 150,000 cryopreserved patient tumor samples stored within the Company’s proprietary biobank.

Importantly, with more than 20 years of longitudinal patient and drug response data, the study demonstrated that the samples stored in the biobank continue to produce drug response data that is consistent with their original clinical testing results. This is critical for predicting outcomes, most notably overall survival (OS), for guiding personalized therapies, target validation, and in silico modeling of drug-tumor responses.

To successfully demonstrate the reproducibility of drug response results for these biobank samples, a comparative study was executed using previously generated drug responses across a subset of patient ovarian tumor samples maintained in the Company’s biobank. These samples had originally been tested and cryopreserved between 2008 and 2016.

Concordance of drug response results between the original fresh patient sample testing and long-term cryogenically stored tumor material from the same patient was 100%.

“We are extremely pleased with the results of this study, which demonstrates that even after an extended period of time – some as long as 16 years – the samples cryopreserved in our biobank remain viable and able to deliver the same drug response data as when originally tested,” said Dr. Arlette Uihlein, SVP of Translational Medicine and Drug Discovery at Predictive Oncology. “This not only validates the utility of our biobank, but also the strength and reliability of the drug response data that we compiled over those many years. We are uniquely positioned to enable drug developers to query patient responses to their drug candidates, accounting for real-world patient heterogeneity, and to validate targets and biomarkers long before human clinical trials commence.”

“Our biobank of more than 150,000 tumor specimens, 200,000 pathology slides, and 20 years of actionable drug and tumor response data represent key assets that are unique to Predictive Oncology,” stated Raymond Vennare, Chief Executive Officer of Predictive Oncology. “With these capabilities, we can build models capable of accurately predicting patient outcomes, allowing us to play a key role in guiding personalized therapies, and discovering novel biomarkers. The results of this study demonstrate the long-term viability of these tumor samples, underscoring its value not only to Predictive Oncology, but our drug developer partners as well.”

Predictive Oncology also announced today the release of a new white paper that discusses this study, and the importance of tumor sample viability, in greater detail. The white paper can be accessed at: https://predictive-oncology.com/blog/reproducible/
