A marketed disposable DPI designed for extreme ease of use.

TwinCaps is designed for applications where a pre-filled, disposable, economic device is needed. It introduces a patent-granted design targeting extreme ease of use even to inhaler naïve patients. Inhaling the dose is simple with TwinCaps: patients only need to perform one operational step to access the pre-filled dose and inhale. Its market-proven usability makes TwinCaps a lead candidate for acute and rescue treatments.

TwinCaps is highly cost-effective as it is manufactured and pre-filled using only two plastic components. It is compatible with doses up to 60 mg and capable of delivering high deposition efficiency with a wide range of formulations, from carrier-based to engineered formulations. Its two, separate dose compartments allow multiple drugs to be delivered independently. Under a clear configuration, TwinCaps provides visual feedback that the complete doses have been inhaled.

In addition to TwinCaps device supply, Hovione provides all formulation development services and TwinCaps device filling for the targeted indication. We can conduct fully integrated device and formulation development and optimization. Hovione can provide Generic and Innovator drug developments from proof-of-concept to scale-up and manufacturing of clinical and commercial drug product supply.
