Abstract

Objective: This study assessed training time with the dulaglutide single-use pen (SUP) and the insulin degludec disposable prefilled pen (FlexTouch®) in self-injection-naïve patients with type 2 diabetes mellitus (T2DM) in Japan.

Methods: This multi-center, open-label, comparative, crossover study measured training time with the dulaglutide SUP vs FlexTouch®. Participants learned how to use both devices in a randomly assigned order. Healthcare providers (HCP) conducted the training. The primary end-point was the time required to train self-injection-naïve T2DM participants to self-inject correctly using each device. Secondary end-points included performance measures, such as success and error rates, patient perceptions related to ease-of-use, and factors associated with training time and performance.

Results: Overall, 48 participants were randomized and completed the study. The mean training time to achieve correct administration was significantly shorter with the dulaglutide SUP vs FlexTouch® (7.4 min vs 19.7 min, p < .001). The proportions of participants who successfully completed the mock injection without error were similar for both devices. Ninety-two percent (44/48) of participants reported that the dulaglutide SUP was easier to use than FlexTouch®.

Conclusions: In this study, participants required a shorter training time to achieve correct administration with the dulaglutide SUP, and had a higher preference for the dulaglutide SUP, when compared to FlexTouch®. These data suggest that the dulaglutide SUP is easy-to-use, which may decrease the burden on HCPs to train diabetic patients how to administer injection therapy and reduce patient injection hurdles, such as needle fear.
