General information about the trial
|
|||
Main objective of the trial |
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.
|
||
Protection of trial subjects |
The study was conducted by investigators experienced in the treatment of paediatric subjects. The parent(s) or guardian(s) as well as the children were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time. In addition to the consent form for the parent(s)/guardian(s), an assent form in child-appropriate language was provided and explained to the child. Repeated invasive procedures were minimized. The number of blood samples as well as the amount of blood drawn were adjusted according to age and weight. A topical anaesthesia may have been used to minimize distress and discomfort.
|
||
Background therapy |
Insulin lispro (Humalog®) was provided as principal bolus insulin for subcutaneous injection in the form of either pen device doseable in 0.5 units increments or vials of lispro 100 units per millilitre (U/mL). Multiple injections were given before meals and/or at bedtime at the discretion of the Investigator. Regular human insulin could be used as bolus insulin as well. | ||

Event Rate of "All Hypoglycemia" | ||||||||||||
End point description |
Defined as the Total Number of Episodes Divided by the Total Duration of the On-treatment Period in Years (Events Per Patient-year).
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 subjects' 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.
The efficacy population consisted of all randomized subjects who received at least one dose of the study medication (modified intent-to-treat [mITT] population). For efficacy analyses, subjects were analyzed in the treatment group allocated by the Interactive Voice Response System (IVRS) at randomization (as randomized).

Event Rate of "All Hypoglycemia" | ||||||||||||
Statistical analysis description |
The sample size was calculated to ensure sufficient power so that the upper bound of the 2-sided 95% confidence interval (CI) for the Lantus/NPH ratio would not exceed 1.15 based on an expected overall rate of "all hypoglycemia“ of 80 events per patient-year of exposure to NPH insulin and to Lantus. It was planned to randomize at least 45 and up to approximately 60 subjects in each of the 2 treatment groups so that at least 70 subjects would complete the 24 weeks of treatment.

Notes [1] - Noninferiority would be demonstrated if the upper bound of the 95% CI for the ratio of the rate of “all hypoglycemia” in the Lantus group to the rate in the NPH group was <1.15. Superiority would be demonstrated if the upper bound of the 95% CI was <1. The margin for noninferiority corresponded to one-half of the 30% difference in hypoglycemia event rate considered as a clinically significant difference by American Diabetes Association 2005 Working Group on Hypoglycemia. |

Severe symptomatic hypoglycemia: any event with clinical symptoms considered to result from a hypoglycemic episode for which the subjects required the assistance of a third party (that is, other than the subjects, or a parent/usual caregiver; for example, from emergency personnel), because the subjects/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. Analysis was performed on mITT population.

Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
There are numerous potential biases that could affect the timing and frequency of performance of sporadic FSBG, such as mealtime dosing and choice of bolus insulin dose, stability and familiarity with insulin regimens, and parental anxiety levels. |
