An effective analysis of clinical trials data involves analyzing different types of data such as heterogeneous and high dimensional time series data.The current time series analysis methods generally assume that the series at hand have sufficient length to apply statistical techniques to them. Other ideal case assumptions are that data are collected in equal length intervals, and while comparing time series, the lengths are usually expected to be equal to each other. However, these assumptions are not valid for many real data sets, especially for the clinical trials data sets. An addition, the data sources are different from each other, the data are heterogeneous, and the sensitivity of the experiments varies by the source. Approaches for mining time series data need to be revisited, keeping the wide range of requirements inmind. In this paper, we propose a novel approach for information mining that involves two major steps: applying a data mining algorithm over homogeneous
