Abstract
Since insulin pens were first introduced in 1985, many advances have been made in pen needles (PNs). In this study we evaluated patient-reported outcomes of an investigational newly re-engineered 4 mm × 32G PN, the BD Nano™ 2nd Gen (also known by its "PRO" brand extension in many markets outside of the USA). In place of a conventional cylindrical posted hub, the investigational PN's hub is contoured with an expanded surface area. The investigational PN also includes a redesigned inner shield that includes tactile ridges and a remodeled outer cover with improved proportions and attachment grips. This was a multi-site, prospective, open-label, two-period crossover trial. Individuals with type 1 and type 2 diabetes using 32G PNs of ≤ 6 mm in length for ≥ 4 months were eligible. Subjects using 31G PNs of a similar length were eligible after a 2-week wash-in period. Subjects were assigned to one of four groups, with each group using a commercially available PN to which the investigational PN was compared. Each of the two study periods were 15 days: one with the investigational PN and the other with a comparator PN. After completing both study periods, subjects compared experiences between the two PN types. A 150-mm comparative v...Continue Reading
