On June 22, 2020 KIYATEC, Inc. reported that it will present data at the 2020 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, June 22-24, revealing how its 3D cell culture models characterize ex vivo tumor response and immunoreactivity to immune checkpoint inhibitors (i.e. PD-1, PD-L1 inhibitors) in solid tumors (Press release, KIYATEC, JUN 22, 2020, View Source [SID1234561347]). These emerging capabilities address a significant unmet need in both preclinical drug development and clinical decision-making in oncology.

PD-1/L1 inhibitors have experienced meteoric growth over the last decade, offering hope to hundreds of thousands of cancer patients every year in the US alone. However, typically no more than 25-30% of eligible cancer patients who receive PD-1/L1 inhibitors actually respond to them. Given that the direct costs associated with PD-1/L1 therapy can run into the hundreds of thousands of dollars per patient, KIYATEC believes that pre-treatment, patient-specific PD-1/L1 response prediction could one day offer clinicians, patients and payers a more objective basis for determining PD-1/L1 inhibitor patient eligibility vs. today’s commonly used population-based biomarkers.
Evidence presented by KIYATEC at AACR (Free AACR Whitepaper) 2020 will highlight findings of the company’s ability to detect dose-dependent response to checkpoint blockade and corresponding correlation with immune cell activation in high-throughput ex vivo 3D tumor spheroid models. KIYATEC believes these recent advances may represent key building blocks toward the eventual development and validation of clinical assays capable of accurate pre-treatment, patient-specific prediction of response to immuno-oncology drugs.
"We’re constantly innovating and expanding the capabilities of our 3D cell culture technologies to reduce the cost and risk of preclinical drug development for our immuno-oncology customers," said Matthew Gevaert, CEO of KIYATEC. "As we continue to make these advances in immuno-oncology drug response on higher-throughput platforms, we can begin to envision a time when such capability would inform clinical decision-making for cancer patients as well."
