ALAMEDA, Calif., Jan. 30, 2019 (GLOBE NEWSWIRE) -- BioTime, Inc. (NYSE American: BTX), a clinical-stage biotechnology company focused on degenerative diseases, today announced that its affiliate company, OncoCyte Corporation (OncoCyte) (OCX), a developer of novel, non-invasive tests for the early detection of cancer, has reported positive results from an R&D validation study of DetermaVuTM, a non-invasive, liquid biopsy test intended to facilitate clinical decision making in lung cancer diagnosis. As outlined in OncoCyte's announcement, the R&D validation study demonstrated a sensitivity of 90% (95% CI 82%-95%) and specificity of 75% (95% CI 68%-81%) of DetermaVuTM on a prospectively collected cohort of 250 patient blood samples that were blinded to laboratory operators. A 95% confidence interval (CI) suggests that there is a 95% chance that test performance will be within the stated range.
According to OncoCyte, these results indicate that DetermaVuTM significantly exceeds the critical parameters necessary for use in lung cancer diagnosis and clearly outperforms reported results from competitors' tests and other clinical models. OncoCyte believes that the potential U.S. market opportunity for DetermaVuTM is $4.7 billion. OncoCyte intends to make DetermaVuTM commercially available in the second half of 2019.
