Electrostatic spray drying for monoclonal antibody formulation.

ABSTRACT: This study explored the feasibility of electrostatic spray drying for producing a monoclonal antibody (mAb) powder formulation at lower drying temperatures than conventional spray drying and its effect on protein stability. A mAb formulation was dried by either conventional spray drying or electrostatic spray drying with charge (ESD). The protein powders were then characterized using solid-state Fourier transform infrared spectroscopy (ssFTIR), differential scanning calorimetry (DSC), size exclusion chromatography (SEC), and solid-state hydrogen/deuterium exchange with mass spectrometry (ssHDX-MS). Particle characterizations such as BET surface area, particle size distribution, and particle morphology were also performed. Conventional spray drying of the mAb formulation at the inlet temper
