GREENVILLE, S.C.--(BUSINESS WIRE)--KIYATEC, Inc. today announced the first clinical use of its response-prediction test to improve outcomes in relapsed brain cancer patients. Test results that measure the effect of cancer drugs on a patient’s live cancer cells are available in just seven days, thereby enabling oncologists to select drugs informed by patient-specific evidence of response before treatment begins.
Lindsay Lipinski, MD, Assistant Professor of Oncology and a neurosurgeon at Roswell Park Comprehensive Cancer Center (Buffalo, NY), presented her and her colleagues’ findings at the 2020 Society of Neuro-Oncology meeting in November. A case series of seven patients with recurrent high-grade gliomas – six with glioblastoma multiforme (GBM) and one with anaplastic astrocytoma – was detailed.
“In this early experience, tools that can predict a tumor cell’s responsivity to a variety of chemotherapy or other therapeutic agents have already been extremely valuable in guiding treatment decision-making for patients with recurrent high-grade gliomas at our center,” said Dr. Lipinski. “Our results show that we are far along in the paradigm shift toward individualized medicine.”
Today, when these cancers return following a patient’s initial treatment, oncologists do not have evidence-based guidelines to choose which drug therapy to use next. Across several drug options, the typical expectation for the time in which these recurrent patients will remain cancer-free (i.e., median progression free survival or PFS) is only 4 months. The use of KIYATEC’s test results to inform drug selection approximately doubled the typical expectation, achieving a group median PFS of 7.9 months, a significant improvement over expected PFS in these patients.
KIYATEC’s test results informed two of the seven patients’ successful treatment with dabrafenib, a targeted agent. Notably, neither had a typically associated genetic mutation, demonstrating that the test can uncover effective drug options that would have normally been missed.
“Our vision is to successfully translate these study findings into the GBM population at large, including newly diagnosed patients – a population that we’re also actively enrolling and testing in our study,” said Matthew Gevaert, PhD, CEO of KIYATEC. “Today’s positive results in relapsed patients, with a median age of 60 and some having had two or even three relapses, paves the way to do this.”
This first release of data from KIYATEC’s active 3D-PREDICT (ClinicalTrials.gov ID NCT03561207) clinical study coincides with the continued addition of new sites at which high-grade glioma patients can enroll, bringing this study to nine institutions across the United States.
