Title - 鈥淚ntegrated Development for Capsule-based DPIs - Solving New Challenges鈥
Presenters:听
- Susana Saldanha, M.Sc. - R&D Manager, Formulation Development, 四色AV
- Jo茫o Pereira, M.Sc. - R&D Analytical Development, 听Analytical Manager, 四色AV
- Mirjam Kobler Ph.D. - 听Global Business Development Manager, H&T Presspart听
Abstract:
This workshop will address the most relevant aspects of DPI development covering formulation to device development, as well as process optimization and analytical characterization. 听The most common challenges expected at each stage will also be highlighted. A data-based development approach will be applied using risk analysis and structured experimental design based on various case studies, for different development stages, including process optimization and scale-up activities. Starting with a review on the design and development of a highly efficient capsule-based device, the participants will further learn how to use tools to prepare and design development plans to achieve optimal performance from different formulation strategies to drug-device combinations. Case studies will be presented on the interplay of carrier-based and carrier-free formulations, with a newly designed device. The higher focus will be placed on the hurdles of composite particles formulation and process development as well as capsule filling of said challenging formulations. 听Unit operations such as spray drying and capsule filling will be covered during this workshop.

Title - Benchmarking of Particle Engineering Strategies for Nasal Powder Delivery: Characterization of Nasal Deposition using the Alberta Idealized Nasal Inlet
听
Abstract:
Powder formulations of a drug and mucoadhesive polymer have increased residence time in the nasal cavity and can be manufactured by blending, spray-drying or agglomeration of primary particles into chimeral agglomerates (CA). While spray-drying allows particle size control and generation of amorphous solid dispersions, blending is simpler and CA should allow faster dissolution after breakup into smaller particles. The objective of this study was to characterize nasal deposition and benchmark nasal powders manufactured by different particle engineering strategies, namely spray dried microparticles (SDM), CA and blends, using the Alberta Idealized Nasal Inlet (AINI). The AINI method conditions were firstly optimized by selecting appropriate angle of actuation and flow rate. Then, six different formulations prepared with distinct polymers and particle engineering strategies were evaluated.

Title - 鈥淎ddressing challenges in high dose dry powder inhalation: formulation and device鈥
听
Abstract:
High dose delivery to the lungs is gaining momentum to address a diversified array of diseases being treated via respiratory drug delivery, comprising a range of drug classes, spanning from less potent small molecules to biologics. Dry Powder Inhalers (DPI) are the dosage form of choice for delivering high payloads to patients. Still there are opportunities for improvement in terms of ensuring that the formulation addresses the pharmacokinetics needs of the specific drug and indication, in close integration with the device, while ensuring delivery efficiency and safety.听
Herein, different high dose delivery platform approaches are discussed in terms of relative advantages and potential pitfalls, followed by some exemplary case-studies: from small molecules to biologics: development of high dose crystalline formulations and high dose spray dried proteins, as well as implementation of a DPI device suitable for cohesive high dose formulations.听
