A strategy for physical property control of a drug substance has been developed that utilizes a science-based approach to define key drivers for particle control. These drivers are based on in vivo performance (or expected performance), content uniformity of the drug substance in drug product, and manufacturability of drug product. Quality by design principles have been used in developing the strategy. The strategy has been designed to provide expectations in terms of particle control at each state of development, translating to early-phase projects and carrying through until launch and beyond.
