Job Description
The Sterile Product Development (SPD) group is responsible for developing non-oral dosage forms, including injections, implants, inhaled and ocular products, for small, intermediate and large molecules from preclinical toxicology studies through commercialization. Our development teams ensure robust formulation, primary packaging/device, process and manufacturing strategies through deep scientific understanding and characterization, enabling scalable development plans without compromising stability, safety, efficacy or delivery. During development, we leverage smart experimental design, cutting-edge analytical tools and predictive approaches to inform molecule, formulation and process selection. In summary, our team enables the translation of preclinical candidates into non-oral drug products.
