Solid Form Services


The selection of a lead solid form of an API is a critical step in early pharmaceutical development. Determining the most suitable chemical and physical form impacts a range of critical parameters including manufacturability, stability and bioavailability. The selection of a lead solid involves the screening and characterization of chemical forms (free form, salts, hydrates, solvates and cocrystals) and polymorphs and/or amophous forms  Every molecule is different with varying propensity for polymorphism and the formation of hydrates and solvates. Additionally, the physicochemical properties of the molecule and the target product profile will determine the need for screening salts, cocrystals or bioavailability-enhanced formulations. These properties will also determine solubility, dissolution rate and/or manufacturability of any solid form.

Our solid form services are designed for flexibility, and can be readily accessed alone or part of an integrated drug substance and/or drug product development program. These services can be rapidly advanced into crystallization development studies, leveraging Lonza’s extensive infrastructure and expertise in advanced chemical synthesis. Solid form screening and identification are also a core component of our SimpliFiH® Solutions first-in-human services, consisting of integrated and phase-appropriate development of API and drug product and designed for accelerated timelines.

Selection of a solid drug form is a key decision, since an estimated 90% of organic molecules have multiple forms.
