QbD starts with an understanding of the quality target product profile. This allows potential critical quality attributes (CQAs) to be established and a risk assessment performed.
The reality is that several manufacturability problems could be brewing that will rain down during Phase III and cause costly delays, no matter how skilled the product and process may be.
Real-time release testing can be defined as a set of in-process controls that may provide greater assurance of product quality than end-product testing.
As the pharmaceutical industry implements PAT and QbD, their symbiotic nature becomes increasingly obvious. Both are catalysts towards the longer term goals of continuous operation and real-time release — the realization of a transformed way of working. This article reviews changing practice within the pharmaceutical industry using the example of real-time particle size analysis to explore the analytical solutions needed and the benefits they deliver.

Setting meaningful and realistic specifications is an essential element of Quality by Design (QbD). Well-defined specifications control product performance since they derive from correlations between clinical behaviour and the variables measured routinely during processing and for QC. This paper examines the process of setting specifications, taking as an example particle size, a critically important parameter for many pharmaceutical formulations. By Malvern Instruments
QbD is increasingly required in our industry, but there are still gaps in understanding how QbD applies to the biomanufacturing process.
Competition in the generics market has never been greater. At a time when many of the most successful drugs are reaching the patent cliff, opening the floodgates for generic substitutes, generic companies are rushing to target the best candidates and enter the market first.
