Predictive Accuracy of Cell Death Assays

IN SELECT SOLID TUMOR TYPES

The following data compilation of 659 patients from 21 peer reviewed published articles in select solid tumor types establish the positive predictive accuracy of cell death assays at 77.0% and negative predictive accuracies of 87.9%. This breakdown reveals compelling evidence that assay directed therapies could improve response rates, time to progression and survival.
