Summary

Anxiety about needles is a commonly expressed concern by diabetics about beginning insulin therapy. A shorter, thinner pen needle that delivers insulin with the safety and efficacy profile of currently marketed pen needles may appeal to many diabetic patients as the new needle may be perceived as less intimidating and more comfortable. Currently marketed pen needles range in length from 5 to 12.7 millimeters (mm). The primary purpose of this study was to evaluate whether the investigational 4mm x 32 Gauge(G) pen needle manufactured by Becton, Dickinson and Company (BD) provides equivalent glucose control (as measured by fructosamine levels) as the currently marketed BD 5mm x 31 G and BD 8mm x 31 G pen needles (PN)in diabetic subjects with varying insulin dosage regimens.

Detailed description

Within each dose group, subjects were randomly assigned at baseline to one of two study arms. One study arm (4/5 mm PN) compared the BD 4mm PN to the 5mm PN, and the other arm (4/8 mm PN) compared the BD 4mm PN to the 8mm PN, in a crossover fashion. Based on the randomization, subjects used either the 4mm or the other assigned PN (5mm or 8mm) for the first 3 weeks, then switched to the alternate PN for the next 3 weeks. Glycemic control was assessed by serum fructosamine (FRU) levels at the end of each 3 week period. Based on their baseline insulin regimen, subjects were also assigned to an insulin dosing group (Low or Regular) to help ensure balance among treatment arms. Requirements for each group were as follows: Low Dose: largest single dose of insulin each day with a pen device must be less than or equal to 20 units. Regular Dose: largest single dose of insulin each day, with a pen device, must be 21-40 units. Explanation of Visits and Timing of Assessments: Visit 1: * Screening * Informed Consent * Demographics * Inclusion /Exclusion * Hemoglobin A1c measurement (HbA1c) Visit 2 (Baseline:) * Insulin dose group assignment (Low dose or Regular dose) * Randomization * Fructosamine blood sample collected * Dispense pen needle (PN) assigned first Visit 3 (approximately 3 weeks after starting first PN) * Pain rated by subject relative to baseline PN * Review Adverse Events (AEs) and reported events of injection site leakage * Fructosamine blood sample collected * Dispense second assigned PN Visit 4 (approximately 3 weeks after starting second PN): * Review AEs and reported events of injection site leakage * Fructosamine blood sample collected * Pain rated relative to previously used PN * Study Completion

Interventions

Type	Name	Description
DEVICE	4mm x 32G pen needle	For 3 weeks, subjects used this pen needle with their own pen device for all daily insulin injections they usually administered themselves with a pen device. Subjects followed their usual insulin regimen and there was no upper limit on total daily insulin dosage or number of injections. Subjects were advised to inject straight in when using the 4mm PN, with no pinch up.
DEVICE	8mm x 31G pen needle	For 3 weeks, subjects used this pen needle with their own pen device for all daily insulin injections they usually administered themselves with a pen device. Subjects followed their usual insulin regimen and there was no upper limit on total daily insulin dosage or number of injections. Subjects were directed to use pinch-up when injecting in the abdomen or thigh with the 8mm PN, and no pinch-up at other injection sites.
DEVICE	5mm x 31G pen needle	For 3 weeks, subjects used this pen needle with their own pen device for all daily insulin injections they usually administered themselves with a pen device. Subjects followed their usual insulin regimen and there was no upper limit on total daily insulin dosage or number of injections. Subjects were advised to inject straight in when using the 5mm PN, with no pinch up.
