KIYATEC, Inc. today announces that results from its prospective, multi-center pilot study, to investigate their assay’s predictive accuracy and correlation to outcome among newly diagnosed ovarian cancer patients, have been published in Scientific Reports. Study findings represent both a preliminary clinical validation for the company’s ovarian cancer assay and a significant developmental milestone for the assay’s technology platform, known as Ex Vivo 3D Cell Culture (EV3D).
“For ovarian cancer patients and their physicians, this study represents an important step in demonstrating our ability to deliver a robust predictive assay with the potential to positively support therapeutic decision-making and improve patient outcomes,” said Matthew Gevaert, CEO of KIYATEC. “Our mission is to optimize and leverage our EV3D cell culture technology to develop response-predictive clinical assays across a range of solid tumor types and make a difference in the future of cancer care.”
In the study, primary tissue from 92 newly diagnosed ovarian cancer patients were prospectively collected and tested for response to National Comprehensive Cancer Network (NCCN)-recommended frontline chemotherapy drugs at KIYATEC’s central laboratory. Assay results were successfully generated for 83 (90%) patient samples. All 92 patients received standard of care chemotherapy (80% adjuvant, 20% neoadjuvant) independent of the KIYATEC drug response prediction test result.
A total of 44 patients (of the 83 patients tested) met minimum follow-up time of 6 months post-chemotherapy for inclusion in this publication. The KIYATEC assay successfully predicted responders (i.e. platinum sensitive) and non-responders (i.e. platinum resistant) with an accuracy of 89% (39/44, p<0.0001).
Investigators also assessed assay accuracy and correlation to outcome among the 35 of 44 (80%) patients who received adjuvant chemotherapy. In this cohort, the KIYATEC assay correctly predicted responders and non-responders with 89% accuracy (31/35, p=0.0004). From date of surgical debulk, progression free survival (PFS) among test subjects predicted to respond to the first line chemotherapy they received was over 20 months v. 9 months for patients predicted not to respond (p=0.01).
“At present, clinicians have no way of knowing, prior to treatment, which of our newly diagnosed or relapsed ovarian cancer patients will respond or not to approved drug therapies,” said Larry Maxwell, MD, Chairman of Obstetrics and Gynecology and co-director of Inova’s Women’s Health Integrated Research Center (WHIRC), and an author of the study. “To predict a complex future result with very high accuracy is a meaningful achievement, especially given that sometimes these outcomes take months to define. Similar test performance in larger, follow-on studies would establish this as a go-to tool in cancer drug selection that should help improve patient outcomes in ovarian cancer.”
Based on these promising findings, KIYATEC has opened a prospective, pivotal clinical study, 3D-PREDICT (NCT03561207), in 500 patients to further validate EV3D-enabled clinical assays for newly diagnosed and recurrent ovarian cancer (8-drug panel) and glioblastoma (12-drug panel). The study is currently open to enrollment.

GREENVILLE, S.C.-- KIYATEC, Inc., today announced that Oregon Health & Science University (OHSU) Knight Cancer Institute has initiated patient enrollment into KIYATEC’s clinical study, 3D-PREDICT, to validate the company’s test as a patient-specific predictor of response to cancer therapies for solid tumors.
In this clinical study, the test analyzes a patient’s live cancer cells, grown in KIYATEC’s laboratory within a biologically-relevant 3D microenvironment, to determine whether or not those cells respond to guideline-recommended cancer drugs. Evidence from the company’s earlier pilot study established a correlation between patient-specific predicted tumor response and actual patient clinical response to cancer therapy. The 3D-PREDICT study is a fully prospective, multi-institutional effort to validate the predictive accuracy of the test and correlate response predictions to clinical outcomes among patients with newly diagnosed and relapsed ovarian cancer, glioblastoma and certain rare tumors.
At present, the OHSU Knight Cancer Institute is enrolling newly diagnosed and relapsed ovarian cancer patients into the 3D-PREDICT Study.
“As a pioneer in personalized cancer care, the OHSU Knight Cancer Institute is deeply committed to optimizing appropriate therapy for our patients as early as possible following diagnosis, when the disease is most treatable,” said Dr. Koen De Geest, lead investigator of the clinical trial at OHSU. “Five-year survival among high-grade ovarian cancer patients is 30%, and we believe this test has the potential to help improve outcomes in the clinic.”
“With cancer treatment, and especially ovarian cancer, time is of the essence and being able to measure patient-specific evidence of response and non-response before treatment begins can truly change the future of cancer care,” said Matthew Gevaert, CEO of KIYATEC. “We welcome OHSU to our clinical study and their participation will be integral as we work to deliver accurate predictions of patient response to cancer therapies, reducing the need for patients to undergo treatments that may not work.”
The 3D-PREDICT study is anticipated to continue through 2022. Details on the trial can be found on https://clinicaltrials.gov/ct2/show/NCT03561207.
About KIYATEC, Inc.
KIYATEC is changing the future of cancer care by accurately predicting patient-specific response and non-response to therapies before treatment begins. Wasted time is the enemy of cancer patients and there is currently no way to accurately predict which cancer patients will respond to standard oncology treatments. KIYATEC has developed a validated process to use a cancer patient’s own live cells to accurately predict treatment response prior to beginning treatment.
