BeyonDevices DPI is designed with simplicity in mind. This simplicity is helpful both to patient and health practitioners alike since they are training patients to use the devices correctly.
In terms of potential benefits for the patient we look to a solution delivering a higher percentage of drug dose to the lung while less drug is deposition in the pulmonary route.
The final product design is focusing on enhancing compliance through small, ergonomic and simple to use solutions, allowing patients to use it properly. The fact we are developing a capsule-based DPI means that breath actuation of the device helps eliminate the coordination issues that occur with other type of inhalers.
Our DPI development focus on providing our clients with a high efficiency in delivering the drug – meaning the use of less drug and increase savings. Other cost savings come from a simple design with fewer parts. Our DPI innovative system provides flexibility in the use of different formulations being available in multiple configurations to meet the needs of each individual application.
During the development of the device design we are focusing on providing protection from moisture ingress while still maximizing the transfer of energy from the user inhalation to the drug formulation in the capsule. Here we pay special attention to the response to low rate profiles on product performance, representative of senior, children and chronically ill patients.
BeyonDevices devised a DPI platform with a focus on ease of use, flexible, inexpensive production and portability while providing an environment where the drug can maintain its stability and producing reproducible dose dosing.
The design of BeyonDevices DPI is developed in such a way that the device design should induce sufficient turbulence and particle-particle collisions to detach drug particles from the carrier surface in interactive mixtures/formulations or deagglomerating particles from large agglomerates of drugs-only formulations. By selecting a unique piercing mechanism to prepare the dose within the capsule for fluidization with tangential flow of air during patient inspiration, BeyonDevices DPI addresses the challenge of different formulations needing different air flow properties within the DPI to adequately aerolise fine particles in order to deliver drugs into the deep lungs. The device body is therefore designed in a way to consistently deliver a high fine particle fraction (FPF) of drugs from different formulations.
The mechanism of piercing the capsule it its unique innovative advantage in its “engine” design/mode of action - introducing specifically designed cannulas to perforate the capsule and provide a controllable air flow - therefore addressing the most difficult requirement from all formulation/drug companies: suitability of usage across a with range of drugs/formulations and doses by easily changing tangential air flow parameters without a need for a total DPI redesign.
Further by being able to produce a cost-effective device with a reduced number of parts BeyonDevices DPI platform can develop into a very attractive disposable device that will overcome the needs for cleaning the device, concerns about product stability and being less expensive with improved patient compliance.
BeyonDevices is the first DPI developer that specifically addresses the two main approaches used to improve the performance characteristics of DPI’s - either focusing on a better device or on a better formulation - in a novel combined way.
We also incorporate into its development process the know-how of market-leading partners from the industry in formulation and capsule manufacturing, therefore focusing on achieving the best performance – always with the patient needs in mind.
BeyonDevices DPI is currently undergoing extensive in vitro testing for the optimization of flow and turbulence characteristics for specific initial set-ups of the capsule perforating mechanism. By combining this information with results from our in-house developed CFD simulations we are creating a working platform that offers the potential of early optimization of the device performance to a specific formulation.
In addition to this testing for performance evaluation BeyonDevices is adding new capabilities to the platform by introducing the first results of its program for “smart packaging”, such as the capacity to collect usage and performance data and transmit it to other electronic platforms.
BeyonDevices is a pioneer in the use of computational fluid dynamics (CFD) for the optimization of device parameters during early stages of DPI development. CFD is used to model the inhalation flow stream, pressure profiles and ultimately particle trajectories.
Coupling CFD simulations with in vitro device and aerosol performance provides important information on the relative contributions of device geometry and formulation for the deagglomeration of particle complexes.
BeyonDevices development methodology uses CFD to look at alterations in device geometry (air inlet area, mouthpiece length) and operating parameters (volumetric flow rate, capsule size) in order to study the flow field and assess carrier particle trajectories within the DPIs during actuation and understand and assess their influence on in vitro aerosol performance.
This unique coupling of experimental and in vitro data allows for a better understanding of the factors that will have an important influence in the optimization of the DPI performance with a specific formulation.
This service is also available from BeyonDevices for development of new DPI geometries or evaluation of existing ones with different formulations.
