A usability study of patients in hemophilia with inhibitors and caregivers who used the Alhemo® pen-injector found that4:

98%

rated the pen easy to

(n=78)

97%

 to use (n=78)

99%

Easy=easy or very easy.

Read IFU for full administration instructions

eAlhemo® is intended for use under the guidance of a healthcare provider, and may be self-administered or administered by a caregiver after appropriate training and reading the Instructions for Use, if a healthcare provider determines that is appropriate.
fAfter the dose counter is at “0,” count slowly to 6 while the needle is still in skin.
FVIII=Factor VIII; IFU=Instructions for Use.

Study design: A device handling study of the Alhemo® pen that included 80 participants: 65 patients (44 adults, 21 adolescents) with hemophilia A or B, with or without inhibitors, using factor replacement or FVIII mimetic therapy (51% on factor, 49% on FVIII mimetic), and 15 caregivers. The main objectives were to determine whether the concizumab pen-injector is easy to learn how to use and easy to use using the Hemophilia Device Handling and Preference Assessment questionnaire. After training, participants independently prepared and performed a single pen injection, administering into an injection pad or manikin. An injection was complete if participant could attach needle, remove outer and inner caps, and set and inject intended dose. Time for training, preparation, injections, and number of complete injections were assessed. Average time to complete an injection was 1 min 21s. Survey rating scale included: Very difficult, Difficult, Neither difficult nor easy, Easy, and Very easy. Limitations: simulated use models may not completely reflect experience of at-home use. In addition, it may be difficult for a participant to evaluate the pen-injector based on a single simulated injection.
