Multivariate data analysis (MVDA) is a highly valuable and significantly underutilised resource in biomanufacturing. It offers the opportunity to enhance our understanding and leverage useful information from complex high-dimensional data sets, recorded throughout all stages of therapeutic drug manufacture. To help standardise the application and promote this resource within the biopharmaceutical industry, this paper outlines a novel MVDA methodology describing the necessary steps for efficient and effective data analysis. The MVDA methodology was followed to solve two case studies: a ‘small data’ and a ‘big data’ challenge. In the ‘small data’ example, a large-scale data set was compared to data from a scale-down model. This methodology enabled a new quantitative metric for equivalence to be established by combining a Two One-Sided Test (TOST) with principal component analysis. In the ‘big data’ example, this methodology enabled accurate predictions of critical missing data essential to a cloning study performed in the ambr15 TM system. These predictions were generated by exploiting the underlying relationship between the off-line missing values and the on-line measurements through the generation of a partial least squares model. In summary, the proposed MVDA methodology highlights the importance of data pre-processing, restructuring and visualisation during data analytics to solve complex biopharmaceutical challenges.
