In the recent years, process analytical technology (PAT) has been widely used on the pharmaceutical development and manufacturing for better process understanding and control. For example, the information of the in-situ particle size distribution by Particle Track (Lasentec ® FBRM) is invaluable on the crystallization development and scale-up. This paper discussed a case of solid state development of a drug candidate that has high tendency to form solvates in most process solvent systems. The only feasible pathway to produce the desired non-solvated form was through a slurry conversion after adjusting the solvent composition through solvent swap distillation. Multiple PAT tools have been evaluated for process understanding and in-line monitoring of a form conversion process, for example, 1) the use of PVM to monitor the conversion of morphology, 2) the use of the FTIR to monitor the progress of de-solvation 3) the use of the combination of Particle Track and Raman for solid form control.
