A Study of Insulin Lispro Mix in Type 2 Diabetic Asian Patients

Phase 4

Completed

• Conditions: Diabetes Mellitus, Type 2
• Interventions: Drug: Lispro Mix 50/50

• Registration Number: NCT00971997
• Lead Sponsor: Eli Lilly and Company

Brief Summary

The purpose is to evaluate the proportion of subjects achieving a Hemoglobin A1c (HbA1c) level below 6.5%, when lispro mix 50/50 is introduced in a stepwise manner from every day (QD) administration to type 2 diabetic patients who have failed to achieve adequate glycemic control on oral antidiabetic drugs (OADs).

Detailed Description

A multicenter, non-randomized, open-label, post-marketing clinical study. The target population of the study is type 2 diabetic patients who have failed to achieve adequate glycemic control on OADs. The study consists of 4 periods: Lead-in Period (2 to 4 weeks), Study Period I (16 weeks), Study Period II (16 weeks), and Study Period III (16 weeks). The regimen of lispro mix 50/50 injection will be changed every 16 weeks based on the HbA1c level. During Study Period I, all the subjects will be given a once daily (QD) injection of lispro mix 50/50. During Study Period II, the regimen of lispro mix 50/50 injection will be changed to twice daily (BID) if the HbA1c level at Week 16 is 6.5% or above, and QD injection will be continued if the value is below 6.5%. During Study Period III, if the HbA1c level at Week 32 is 6.5% or above, the subjects on BID treatment during the previous period (Study Period II) will receive three times daily (TID) injections of insulin.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants Achieving Hemoglobin A1c (HbA1c) Below 6.5% at Week 48 Endpoint	Week 48	Hemoglobin A1c (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. The 6.5% HbA1c is the Japan Diabetes Society (JDS) value, and is equivalent to the National Glycohemoglobin Standardization Program (NGSP) HbA1c value of 6.9%.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants Achieving Hemoglobin A1c (HbA1c) Below 6.5% at Week 16 and Week 32 Endpoints	Week 16 and Week 32	Hemoglobin A1c (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. The 6.5% HbA1c is the Japan Diabetes Society (JDS) value, and is equivalent to the National Glycohemoglobin Standardization Program (NGSP) HbA1c value of 6.9%.
Percentage of Participants Achieving Hemoglobin A1c (HbA1c) Below 7.0% at Week 16, 32 and 48 Endpoints	Week 16 and Week 32 and Week 48	Hemoglobin A1c (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. The 7.0% HbA1c is the Japan Diabetes Society (JDS) value, and is equivalent to the National Glycohemoglobin Standardization Program (NGSP) HbA1c value of 7.4%.
Percentage of Participants Achieving Hemoglobin A1c (HbA1c) Level Below 6.5% and Below 7.0% by Regimen at Week 48 Endpoint	Week 48	Hemoglobin A1c (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. 6.5% and 7.0% HbA1c are the Japan Diabetes Society (JDS) values, and are equivalent to the National Glycohemoglobin Standardization Program (NGSP) HbA1c values of 6.9% and 7.4%, respectively.
Change From Baseline in Hemoglobin A1c (HbA1c) at Week 48 Endpoint	Baseline, Week 48	Hemoglobin A1c (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time.
Change From Baseline in Fasting Glucose at Week 48 Endpoint	Baseline, Week 48
Change From Baseline in Blood Glucose Profile at Week 48 Endpoint	Baseline, Week 48	Time course of changes in blood glucose was determined by 7-point self-monitoring of blood glucose (SMBG) during the day (before breakfast, lunch, and dinner, 2 hours after the start of each meal, and at bedtime).
Change From Baseline in Fasting C-Peptide at Week 48 to Endpoint	Baseline, Week 48	C-peptide is a protein that is produced in the body along with insulin.
Change From Baseline in Fasting Serum Lipids at Week 48 Endpoint	Baseline, Week 48
Change From Baseline in Body Weight at Week 48 Endpoint	Baseline, Week 48
Total Daily Dose of Insulin at Baseline, Week 16, Week 32 and Week 48	Baseline and Weeks 16, 32 and 48
Percentage of Participants Developing Hypoglycemia at Any Time From Baseline Through Week 48	Baseline through Week 48	Results are reported as the percentage of participants experiencing hypoglycemia, which was considered any hypoglycemic event in which participants themselves recognized hypoglycemia-related signs and symptoms, or they had a blood glucose level below 50 milligram/deciliter (mg/dL) regardless of signs, symptoms or the relationship to treatment.
Number of Hypoglycemia Episodes Participants Experienced at Any Time From Baseline Through Week 48	Baseline through Week 48	A hypoglycemic episode was considered any hypoglycemic event in which participants themselves recognized hypoglycemia-related signs and symptoms, or participants had a blood glucose level below 50 mg/dL regardless of signs, symptoms or the relationship to treatment.
