Details and patient eligibility

About

Primary Objective:

To assess patient preference for Lantus SoloSTAR pen versus Lantus vial and syringe at the end of Crossover Phase (Week 4) in patients with type 2 diabetes mellitus (T2DM)

Secondary Objectives:

To compare Lantus SoloSTAR pen versus Lantus vial and syringe with regard to the following parameters:

Randomization/Crossover phase:

• Healthcare professional's (HCP) recommendation for Lantus SoloSTAR pen versus Lantus vial and syringe

Re-randomization phase:

• Change in Fasting Plasma Glucose (FPG) from week 4 to week 10
• Percentage of patients achieving FPG<110 mg/dL at week 10
• Change in Lantus dose injected per day (U) from week 4 to week 10

Observational phase:

• Percentage of patients achieving glycosylated hemoglobin (HbA1c) goal (<7%) at week 40
• Time to first observation of HbA1c<7% during the observational phase
• Percentage of patients who discontinue Investigational Product (IP) during the observational phase due to dissatisfaction with their current device

All phases:

• Percentage of patients who discontinue IP during each phase of the study
• Safety assessment such as occurrence of hypoglycemic events (HE) and adverse events (AE)

Full description

This study consisted of a 1 week Screening Phase, a 4-week Randomization/Crossover Phase, a 6-week Re-randomization Phase, followed by a 30 week Observational Phase.

The total duration of study participation was up to 41 weeks with a total treatment duration of up to 40 weeks of Lantus exposure.

Enrollment: 405 patients

Sex: All

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

• Patients who were pregnant or breastfeeding
• Women of childbearing potential not protected by a highly effective contraceptive method of birth control (as defined for contraception in the Informed Consent Form and /or in a local protocol addendum) and/or who were unwilling or unable to be tested for pregnancy
• Patients with impaired renal function as shown by serum creatinine ≥1.5 mg/dL for males or ≥1.4 mg/dL for females at screening
• Patients with clinical evidence of active liver disease, or serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) 2.5 times the upper limit of the normal range (ULN)
• Patients unlikely to comply with the protocol requirements (eg, illiterate, uncooperative, unable to return for scheduled visits, unlikely to complete the study)
