  • Patent number: 12449198
    Abstract: Lyophilization methods for preparing protein formulations for long-term storage at room temperature or improved stability at refrigeration storage are provided. Specifically, the present application provides lyophilization methods to obtain a target percentage of residual moisture of a lyophilized product, such as 3-5% residual moisture. The secondary drying of the lyophilization can be conducted under controlling rate of desorption under a temperature which is similar to the shelf temperature of the primary drying. Alternatively, the lyophilization can be conducted without a distinguished secondary drying step.
