6-month Comparison of Morning Lantus Versus Neutral Protamine Hagedorn Insulin in Young Children With Type 1 Diabetes

Phase 3

Completed

• Conditions: Type 1 Diabetes Mellitus
• Interventions: Drug: Insulin glargine (HOE901); Drug: Neutral Protamine Hagedorn (NPH) insulin; Drug: Insulin lispro

• Registration Number: NCT00993473
• Lead Sponsor: Sanofi

Brief Summary

The primary study objective was to compare the rate of "all hypoglycemia" (composite outcome of the following hypoglycemia events: symptomatic hypoglycemia episodes, low continuous glucose monitoring system (CGMS) excursions confirmed by fingerstick blood glucose (FSBG), low FSBG readings performed at other times) between children treated with Lantus (insulin glargine) and Neutral Protamine Hagedorn (NPH) insulin.

Secondary objectives were to compare insulin glargine and NPH in terms of:

* rates of specific types of hypoglycemia: symptomatic, severe, nocturnal, nocturnal symptomatic, and severe nocturnal symptomatic hypoglycemia

* HbA1c change from baseline to end-of-treatment, and HbA1c at end-of-treatment

* percentage of patients reaching HbA1c less than 7.5% (target value) at end of treatment

* average blood glucose over whole trial and at end of trial, as estimated by continuous glucose monitoring (CGM), and blood glucose variability

Detailed Description

Screening phase: 2 to 4 weeks

Treatment phase: 24 weeks

At randomization, patients were stratified with respect to their baseline HbA1c level (\<8.5% or ≥8.5%) and hypoglycemic event rate (number of CGMS hypoglycemic excursions \<0.5 or ≥0.5 events per 24 hours). Following randomization, trial basal insulin was initiated and up-titrated within the first 12 weeks to reach a stable dose.

Follow-up phase: 2 weeks

All Phases: 28 to 30 weeks

Arm && Interventions

Group	Intervention	Description
Lantus (insulin glargine)	Insulin glargine (HOE901)	Lantus given as basal insulin once a day in the morning by subcutaneous injection
Lantus (insulin glargine)	Insulin lispro	Lantus given as basal insulin once a day in the morning by subcutaneous injection
NPH insulin	Insulin lispro	Neutral Protamine Hagedorn (NPH) human insulin given as basal insulin either once or twice per day generally in the morning and /or at bedtime by subcutaneous injection
NPH insulin	Neutral Protamine Hagedorn (NPH) insulin	Neutral Protamine Hagedorn (NPH) human insulin given as basal insulin either once or twice per day generally in the morning and /or at bedtime by subcutaneous injection

Primary Outcome Measures

Name	Time	Method
Event Rate of "All Hypoglycemia" Defined as the Total Number of Episodes Divided by the Total Duration of the On-treatment Period in Years (Events Per Patient-year)	6 months	The rate of "all hypoglycemia" was calculated from "all hypoglycemia" episodes which occurred during the 24-week on-treatment period and consisted of: - symptomatic hypoglycemia episodes validated by the study investigator based on entries in patients' diaries, - low continuous glucose monitoring system (CGMS) excursions (interstitial glucose \<70 mg/dL \[3.9 mmol/L\]) confirmed by fingerstick blood glucose (FSBG) \<70 mg/dL, - low FSBG readings (values \<70 mg/dL) performed at other times.

Secondary Outcome Measures

Name	Time	Method
Event Rate of Severe Symptomatic Hypoglycemia Defined as the Total Number of Episodes Divided by the Total Duration of the On-treatment Period in Years	6 months	Severe symptomatic hypoglycemia: any event with clinical symptoms considered to result from a hypoglycemic episode for which the patients required the assistance of a third party (ie, other than the patient, or a parent/usual caregiver; eg, from emergency personnel), because the patients/parents could not treat the event with acute neurological impairment directly resulting from the hypoglycemic event. The occurrence of seizure, coma, unconsciousness, or the use of glucagon, were also to qualify a hypoglycemic episode as severe.
Event Rate of Symptomatic Hypoglycemia (Individual Component of Primary Endpoint) Defined as the Total Number of Episodes Divided by the Total Duration of the On-treatment Period in Years (Events Per Patient-year)	6 months	Symptomatic hypoglycemia: any event with clinical symptoms considered to result from hypoglycemia, validated by the study investigator based on data from patient diaries.
Event Rate of Nocturnal Hypoglycemia Defined as the Total Number of "All Hypoglycemia" Episodes Divided by the Total Duration of the On-treatment Period in Years	6 months	Nocturnal hypoglycemia: any event from the "all hypoglycemia" total that occurred between 23:00 and 07:00 hours.
Event Rate of Nocturnal Symptomatic Hypoglycemia Defined as the Total Number of Episodes Divided by the Total Duration of the On-treatment Period in Years	6 months	Nocturnal symptomatic hypoglycemia: any symptomatic hypoglycemic event that occurred between 23:00 and 07:00 hours.
Event Rate of Severe Nocturnal Hypoglycemia Defined as the Total Number of Episodes Divided by the Total Duration of the On-treatment Period in Years	6 months	Severe nocturnal symptomatic hypoglycemia: any severe symptomatic hypoglycemic event that occurred between 23:00 and 07:00 hours.
Glycosylated Hemoglobin A1c (HbA1c): End of Treatment and Change From Baseline to End of Treatment	baseline, 6 months
Glycosylated Hemoglobin A1c (HbA1c): End of Treatment and Change From Baseline to End of Treatment (ANCOVA Estimates)	baseline, 6 months	Assessed using an analysis of covariance (ANCOVA) model with treatment, and randomization strata (baseline number of CGM hypoglycemic excursions \<0.5 events/24hours or ≥0.5 events/24 hours, and baseline HbA1c \<8.5% or ≥8.5%) as fixed effects, and using the baseline value as covariate.
Percentage of Patients Reaching HbA1c Target of Less Than 7.5% at the End of Treatment Visit	6 months	Percentage of patients reaching International Society for Pediatric and Adolescent Diabetes (ISPAD)-recommended goals of Glycosylated Hemoglobin A1c \<7.5% at the end of treatment visit.
Average Daily Blood Glucose (BG) Based on CGMS Values: End of Treatment and Change From Baseline to End of Treatment	baseline, 6 months
