Cover Story: We compared different methods, including thermodynamic models, conventional experimental screening methods, and a novel atomization screening device, in their ability to predict drug–polymer miscibility and the solid-state properties of specific drugs during the development of spray-dried amorphous solid dispersions (SDASDs). The phase behavior and solid-state properties of each sample were characterized by modulated DSC and X-ray powder diffraction. Principal component analysis was performed to assess the prediction accuracy of various screening approaches. Our novel atomization device displayed superior ability compared to conventional screening approaches in predicting the phase behavior of SDASDs, providing insights into the final properties and performance of SDASDs in early drug development.
