Plain English Summary
Background and study aims
Diabetes is a life-long condition where a person is unable to control their blood sugar levels. here are two main types of diabetes. In type 1 diabetes the body is unable to produce a hormone called insulin, which is responsible for breaking down glucose and turning it into energy. When this happens, sufferers need to inject insulin to make sure that their blood sugar levels stay normal. Most people use long-acting insulin to give a continuous low level in the blood stream and a short acting insulin to give a “boost” at meal times. There are several different types of insulin made. This study is looking at the differences between two relatively new insulins, called Detemir (or Levemir) and another one called Glargine (or Lantus). Although it is normal to gain weight with age, girls with diabetes may have more weight gain than girls without diabetes. Levemir appears to cause less weight gain than insulatard (the conventional ‘cloudy’ long acting insulin) in adults and young people with diabetes, but it has never been compared with Lantus in young women. The aim of this study is to find out whether there are any differences in weight gain in young women using these different types of insulin.
Who can participate?
Girls aged between 13 and 20 with T1DM.
What does the study involve?
Participants who agree to take part in the study are randomly allocated to receive either Insulin Detemir (Levemir) or Insulin Glargine (Lantus). The study lasts for one year and involves six clinic visits and regular telephone and/or email contact (minimum 12) with the research nurse. At each visit the participant’s height, weight, blood pressure and waist circumference are measured. The participants are also asked to complete a brief questionnaire about appetite. During the study, participants are asked to check and record their blood sugar before breakfast, their evening meal, before bedtime, and whenever they feel as if their blood sugars are low. At two months, participants are asked to record their blood sugar values on a 5 point profile (breakfast, lunch, evening meal, bedtime and once overnight at around 0200h). In centres which have the necessary equipment, after 3 months and at the very end of the study, glucose values for three days, using a continuous glucose monitoring sensor, are recorded. The sensor is a small electrode that lies just beneath the skin and can convert tiny amounts of glucose into a signal that is sent and stored by the monitor which is downloaded into a computer file. At the beginning and end of the study, where appropriate facilities are available, participants are asked to have a scan to measure body fat distribution. Four times throughout the study; at the beginning, end and after three and six months, blood samples are taken to assess overall glucose control over the preceding three months and levels of other hormones within the blood, such as testosterone, which may vary in young women with diabetes. Anyone can have anaesthetic (numbing) cream applied to the skin before the blood test is done if they prefer.
What are the possible benefits and risks of participating?
There are no direct benefits involved with participating. There is a small risk of pain, bruising or infection when blood samples are taken using blood tests or the continuous glucose monitoring sensor.
Where is the study run from?
Addenbrooke's Hospital and 24 other hospitals in England (UK)

Study information
Scientific title
A comparison of the effects of insulin Detemir with insulin Glargine on weight gain in female adolescents and young adults with type 1 diabetes on a basal bolus regime
Acronym
DETEMIR GLARGINE
Study hypothesis
The aim of this study is to explore the hypothesis that use of insulin detemir versus insulin glargine will lead to reduced weight gain in young women with T1D.

Condition
Topic: Medicines for Children Research Network, Diabetes Research Network; Subtopic: Type 1, All Diagnoses; Disease: All Diseases, Insulin switch, Metabolic, Paediatric
Intervention
Interventions as of 22/05/2017:
Eligible subjects will be randomised to one of two groups using an internet based service (www.sealedenvelope.com) with minimisation of variation in:
1. Age (< or ≥ 16yrs)
2. BMI SDS (< or ≥ 1 SDS)
3. HbA1c (< or ≥ 8 % or 64mmol/mol)
4. Years post menarche (< or ≥ 2yrs)
5. Centre
Randomisation will be 1:1 between the arms. The web based randomisation service is password protected on a secure server and no identifiable patient details will be entered. Following randomisation, a completed form, confirming treatment will be faxed back to the local research team. The local team will then notify their pharmacist in order to facilitate local dispensing prior to the participant attending for their baseline visit.
Group 1: Participants receive Levemir®. 1 ml of the solution contains 100 U insulin detemir* (equivalent to 14.2 mg). 1 pre-filled pen contains 3 ml equivalent to 300 U
Group 2: Participants receive Lantus®. 100 units insulin Glargine (equivalent to 3.64mg). Each pen consist of 3mls of solution (equivalent to 300units)
Both insulins dosages are titrated to fasting glucose aiming for a target range of 4-8mmol/l.
Original interventions:
1. Lantus® Optiset (600 nmol/ml [100 IU/ml] in 3 ml pre-filled, disposable pen device) dosage variable/subcut/frequency once or twice day
2. Lantus® Solostar (600 nmol/ml [100 IU/ml] in 3 ml pre-filled, disposable pen device) dosage variable/subcut/frequency once or twice day
3. Levemir® FLEX-PEN (2400 nmol/ml [100 U/ml] in 3 ml pre-filled, disposable pen device) dosage variable/subcut/frequency once or twice day
Duration of treatment: one year
Duration of follow-up: No follow-up
Study entry: single randomisation only
