De-Risking Drug Development: Informatics-Supported Solid Form Selection

Selecting the right solid form is a foundational decision in solid dosage development, with far‑reaching impact on stability, bioavailability, manufacturability, and regulatory success. Experimental polymorph screening remains essential for mapping the solid‑state landscape and identifying candidate crystalline forms, including metastable polymorphs, solvates, and hydrates. However, experimental results alone may not always confirm whether the most stable form has truly been identified. Structural informatics adds a powerful layer of confidence by evaluating crystal structures against large crystallographic databases to assess packing efficiency, hydrogen‑bond networks, and molecular conformations associated with thermodynamic stability. By comparing observed crystal features with statistically favored motifs, informatics can help confirm whether a given form represents the energetic minimum or whether more stable alternatives may exist. Integrating experimental screening with data‑driven structural analysis enables more informed solid‑form selection, reduces the risk of late‑stage form changes, and supports robust, defensible decisions as compounds progress toward development and commercialization.
