Predicting clinical trial terminations
WebResults : In this paper, we demonstrate the interpretive and predictive value of LDA as it relates to predicting clinical trial failure. The results also demonstrate that the combined modeling approach yields robust predictive probabilities in terms of both sensitivity and specificity, relative to a model that utilizes the structured data alone. Webreports. Using machine learning to model clinical trial terminations allows for a greater under-standing of the specific factors that may lead to terminated clinical trials. These models can also be applied to current or planned trials to understand their probability of completion vs termination.
