Summary:Compositions including solid forms of polypeptides such as crystalline antibodies, and related methods, are generally described. The compositions may include carriers such as hydrogels that at least partially encapsulate the solid form of the polypeptides (e.g., crystals, amorphous solids). Encapsulation with certain of the materials described may result in compositions containing relatively high loadings of polypeptides while in some instances retaining structural and functional properties of the polypeptides useful for certain types of administration to subjects (e.g., for prophylactic or therapeutic applications). In some instances, compositions having relatively low dynamic viscosities while having relatively high polypeptide loadings are provided. L'invention concerne globalement des compositions comprenant des formes solides de polypeptides tels que des anticorps cristallins, et des méthodes associées. Les compositions peuvent comprendre des véhicules tels que des hydrogels qui encapsulent au moins partiellement la forme solide des polypeptides (par exemple, des cristaux, des solides amorphes). L'encapsulation avec certains des matériaux décrits peut avoir pour conséquence des compositions contenant des charges relativement élevées de polypeptides tout en maintenant, dans certains cas, les propriétés structurales et fonctionnelles des polypeptides utiles pour certains types d'administration à des sujets (par exemple, pour des applications prophylactiques ou thérapeutiques). Dans certains cas, on obtient des compositions ayant des viscosités dynamiques relativement faibles tout en ayant des charges de polypeptides relativement élevées.
