ABSTRACT:
The present invention provides storage stable dry powder compositions of IL-4R. The powder compositions demonstrate superior chemical and physical stability over their solution counterparts, particularly upon storage under varying conditions of temperature and humidity. Moreover, the powders, as prepared, possess good aerosol properties, which are maintained upon storage.
