Usability Clinical Trial
— DPI-6Official title:
Usability of Levodopa Cyclops™ Compared to INBRIJA® During an Off Episode in Parkinson's Disease Patients
Currently there is one Levodopa inhaler on the market, the INBRIJA® inhaler. When looking at the user instructions for the INBRIJA®, multiple steps are necessary including preparing and cleaning the inhaler. The Levodopa Cyclops™ inhaler also requires steps to be ready-for-use, however there are less steps required to reach this 'ready-for-use' state. This is mainly because the medicine (Levodopa) is already prefilled in the inhaler. Moreover, the Levodopa Cyclops™ is a single-use inhaler and cleaning steps are not necessary. Since both inhalers should be used during off episodes, there might be a preference for one inhaler over the other due to the instructions. An off episode might impair the ability and length to successfully operate an inhaler due to mental or mobility issues. This study investigates if Parkinson patients have a preference for one of the inhalers based on handling steps, ease-of-use, understandability.

Primary | Correct performance of inhalation maneuvers | The main study parameter is to investigate whether Parkinson's patients perform the correct steps in accordance with the instruction card of respectively the Levodopa Cyclops™ or INBRIJA® inhaler after the primary inhalation instructions. | 15 minutes for performing the inhalation maneuvers with both the placebo inhalers (Inbrija and Cyclops) during a Parkinson's off episode | |
Secondary | Inhaler preference of Parkinson patients | The secondary study parameter is to investigate whether the Parkinson's patients prefer the Levodopa Cyclops™ or the INBRIJA® inhaler by keeping track of the total handling time and by letting the patients fill in a questionnaire keeping track of their experiences regarding the ease-of-use, convenience and preference of the different steps of the inhaler user maneuver | 10 minutes for filling in the questionnaire during or directly after a Parkinson's off episode |
