Primary Outcome Measures:
  • HbA1c change rate from the start to 12 and 24 weeks are investigated and compared. Furthermore, using a questionnaire sheet "IDSQ-J" related to the insulin infusion device, the patient's usability and satisfaction with KwikPen® or FlexPen® are performed. [ Time Frame: 24 weeks ]

Secondary Outcome Measures:
  • As the secondary endpoints, the incidence of hypoglycemia, changes in body weight (BMI) and blood pressure, and the dose of insulin are investigated and compared before and after the changeover. [ Time Frame: 24 weeks ]

Estimated Enrollment: 200
Study Start Date: January 2009
Estimated Study Completion Date: June 2009
Estimated Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
usability and preference Device: KwikPen® and FlexPen®
The treatment is changed to twice a day injection of the same unit of Novo Rapid 30 Mix injection FlexPen® or Humalog Mix 25 injection KwikPen®for 3 months, after which the final assessment is made.

Detailed Description:
  • Concomitant drugs The treatment with other insulin preparation is prohibited during the study period.

    • Important protocol violation
    • When continued treatment is judged difficult due to the onset of an adverse event
    • Death
    • When the follow-up of patient becomes impossible
    • Other than the above, when the investigator judges it necessary to discontinue the study
