Scale-up of spray dried amorphous solid dispersions

European Industrial Pharmacy, December 2013

With an increasing number of relatively insoluble drugs in development today, there is a need to develop and use platform technologies capable of addressing solubility issues. Among the different alternatives, the use of stabilised amorphous solid dispersions is becoming increasingly popular, with pharmaceutical spray drying being one of the key technologies used in their preparation. In spray dried dispersions (SDD), the active pharmaceutical ingredient (API) is molecularly dispersed in a polymeric matrix. The polymer is used to stabilise the amorphous, metastable form of the drug and sustain supersaturation of the API in solution/biological fluids, thereby increasing bioavailability.

Hovione is bringing momentum to the intranasal field after announcing that its lead single-use nasal dry powder device, developed in collaboration with Industrial Design Consultancy Ltd (IDC), is now available for commercial partnerships. The milestone marks the transition from prototype to a fully integrated intranasal drug delivery platform that spans Hovione’s end-to-end partnership capabilities–from API synthesis through advanced formulation and particle engineering to drug product manufacturing, including device supply and advanced analytical tools for nasal performance characterization. The platform’s single-use device is designed to be manufacturable at scale and to leverage existing advanced particle engineering and drug product manufacturing capabilities, a practical advantage that can shorten timelines to clinic and commercialization while reducing development risk and cost. The device’s patented mechanism supports targeted nasal deposition, including access to the upper olfactory region. This enables rapid systemic absorption and potential nose-to-brain delivery pathways that are increasingly important for CNS and emergency-use indications. Beyond the single-use format, Hovione and IDC are advancing a multi-dose variant to broaden applicability across dosing regimens and therapeutic areas. The collaboration is backed by an intellectual property portfolio and initial patent grants, positioning the platform as a turnkey option for pharma partners seeking a single integrated supplier for both drug substance and device. This development arrives as intranasal delivery gains traction for systemic, CNS and rapid-onset therapies. This is precisely the focus of the upcoming 4th Nasal Formulation & Delivery Summit, for which Hovione is a key sponsor. The annual summit unites formulation, delivery and product development leaders to tackle drug-device compatibility, translational preclinical models, and strategies for scalable, regulatory-ready intranasal programs. Hovione’s recent progress will be highly relevant to attendees looking to de-risk nose-to-brain and systemic intranasal programs. Read the full article at News-Medical.net
