Clinical Trial Summary

The purpose of this study is to investigate whether a zinc-free insulin is an effective treatment option for lipoatrophy in patients with type 1 Diabetes (T1D) and insulin pump (CSII, continuous subcutaneous insulin infusion) therapy.

Description:

Randomized, controlled, open-label parallel study. Clinical Study Phase IV After being included in the study, subjects are getting an extensive dermatological examination by a pediatric dermatologist familiar with cutaneous complications of T1D, additionally pathological results will be documented by photography and, if necessary, videodermoscopy. Additionally, an evaluation of their lipoatrophic areas using imaging methods like ultrasound (USG) and MRI will be performed. After randomization, half of the included children switch their pump insulin into insulin glulisine (intervention group) for 6 months. The others continue their current treatment (control group) and switch to insulin glulisine 6 months later. Both groups are followed-up until month 12. Hence, after the 4th visit at 6 months, all enrolled patients are on insulin glulisine pumps for a further period of 6 months.

• Sexually active women of childbearing potential not consistently and correctly practicing birth control by implants, injectables, combined oral contraceptives, hormonal intrauterine devices (IUDs), sexual abstinence or vasectomized partner

• Lack of compliance or other similar reason that, according to investigator, precludes satisfactory participation in the study

• Prisoners or subjects who are involuntarily incarcerated

Target Disease Exclusions

• History of T2DM, maturity onset diabetes of young (MODY), pancreatic surgery or chronic pancreatitis

• Any use of oral hypoglycemic agents within 12 months prior to the screening visit

• History of diabetes ketoacidosis (DKA) within 12 weeks prior to the screening visit

• History of hospital admission for glycemic control (either hyperglycemia or hypoglycemia) within 3 months prior to the screening visit

• Frequent episodes of hypoglycemia as defined by more than one episode requiring assistance, emergency care (paramedics or emergency room care) or glucagon therapy, or more than 2 unexplained episodes of symptomatic hypoglycemia within 3 months prior to the screening visit. An unexplained event is defined as an event that cannot be explained by circumstances such as dietary (e.g. missed meal), strenuous exercise, error in insulin dosing, etc.

• Hypoglycemic unawareness

• History of diabetes insipidus

• History of Addison's disease or chronic adrenal insufficiency

Physical and Laboratory Test Findings

• BMI above 35 kg/m2

• RR > 180/110 mm Hg

• Aspartate aminotransferase (AST) > 3X Upper limit of normal (ULN)

• Alanine aminotransferase (ALT) > 3X ULN

• Serum total bilirubin > 3X ULN

• Estimated GFR (eGFR) < 60 ml/min/1.73 m2

• Hemoglobin = 11.0 g/dl (110 g/l) for boys / men; hemoglobin =10.0 g/dl (100 g/L) for girls / women.

• Creatine kinase (CK) > 3X ULN

• Positive for hepatitis B surface antigen or anti-hepatitis C virus antibody.

• Abnormal Free T4 Note: abnormal TSH value at screening will be further evaluated for free T4. Subjects with abnormal free T4 values will be excluded. A one-time retest may be allowed, as determined by the Investigator, after a minimum of 6 weeks following the adjustment of thyroid hormone replacement therapy in subject who have had a prior diagnosis of a thyroid disorder and who are currently receiving thyroid replacement therapy. Such cases should be discussed with the Investigator prior to retesting.

Related Conditions & MeSH terms

• Diabetes Mellitus, Type 1
• Lipoatrophy
• Lipodystrophy
• Type 1 Diabetes

Intervention

Drug:
• Apidra
Half of patients with lipoatrophy will be switched randomly to insulin Apidra for 12 months. Any site other than the lipoatrophic site would be used for delivering the insulin for the purpose of this study.
• current insulin
Half of patients with lipoatrophy will still use their current Insulin for 6 months. After 6 months the current insulin will be switched to insulin Apidra for the next 6 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Relative thickness as assessed by MRI	The relative thickness will be used instead of raw data of the MRI measurements as given by the thickness of the most atrophic region related to the thickness of the reference region of the same patient (normal tissue). The change (increase) of the thickness is defined as difference between the relative thicknesses of the same atrophic region (given as percentage of the same reference region) at 6 months and study begin.	at 6 months
Secondary	Relative thickness as assessed by MRI	Change of relative thickness (as defined above) at 6 and 12 months in the control group	at 6 and 12 months
Secondary	Relative thickness as assessed by MRI	Change of relative thickness (as defined above) between baseline and 12 months in both arms	at baseline and 12 months
Secondary	Relative thickness as assessed by USG	The relative thickness will be used as given by the thickness of the most atrophic region related to the thickness of the reference region of the same patient (normal tissue).

If available, disease scores such as the SCORAD score for atopic dermatitis or the PASI score for psoriasis vulgaris will be used to document disease activity.	at 6 and 12 months
