Plain English Summary
Background and study aims
Diabetes is a condition that causes blood sugar to become too high. Diabetes is the fastest-growing health problem in the UK affecting over three million people in England. Most of these cases are “type 2” diabetes caused by an unhealthy lifestyle and obesity. By 2035, diabetes will affect 1 in 10 people in the UK. The number of diabetes complications of is also increasing. These include foot ulcers which can lead to amputation. Treatments for foot ulcers often fail and diabetes costs the NHS £1 million an hour. During stress, the body produces the hormone cortisol (a glucocorticoid) which causes skin thinning, poor wound healing and infections. Cortisol is activated in skin by the enzyme 11β-HSD1. Studies in patients with diabetes showed that blocking this enzyme improved disease by reducing body weight, blood sugar and cholesterol levels. Blocking this enzyme could also improve skin function and wound healing. The aim of this study is to test healing in patients with type 2 diabetes using 11β-HSD1.
Who can participate?
Adults with type 2 diabetes.
What does the study involve?
Participants are asked to attend a short screening visit to check heart function, blood pressure and blood tests. Participants are randomly allocated to one of two groups. Those in the first group receive tablets containing the test drug. Those in the second group receive tablets which do not contain the test drug (dummy). Participants are asked to take the tablet for 35 days twice daily. Participants are asked to provide two 24 hour urine samples, four blood samples and five skin biopsies (two at one visit and three at another visit). Skin biopsies are taken from the arm after numbing the area with an injection. Participants are also measured for skin thickness, water loss, water content and nerve function using pain-free probes. Weight, height, blood pressure, waist and hip circumference are also recorded.
What are the possible benefits and risks of participating?
Patients taking the drug tablets may notice a temporary improvement in their diabetes such as lower blood pressure, lower blood sugar, lower cholesterol and weight loss. Patients will contribute to research which may lead to new treatments which they may benefit from in the future. They will be paid £180 in total for their time and travel. The study has been designed with patient safety and comfort as our top priority and has full ethical approval. Possible but unlikely risks include biopsy infection, discovery of previously unknown health issues or side-effects such as mild to moderate stomach upset or headache. If these occur we will take appropriate medical action.

GC-SHealD (Glucocorticoids and Skin Healing in Diabetes) :A double-blind, randomized, placebo-controlled phase II pilot trial investigating efficacy, safety and feasibility of 11β-hydroxysteroid dehydrogenase type 1 inhibition by AZD4017 to improve skin function and wound healing in patients with type 2 diabetes
The aim of this study is to test healing in patients with T2DM using the selective 11β-HSD1 inhibitor AZD4017 which is approved for use in clinical trials.

Specialty: Diabetes, Primary sub-specialty: Type 2; UKCRC code/ Disease: Metabolic and Endocrine/ Diabetes mellitus, Skin/ Other disorders of the skin and subcutaneous tissue
This study aims to conduct a double-blind, randomised, parallel group, placebo-controlled phase II pilot trial of 35 days’ duration with 400mg oral AZD4017 twice daily (n=15) or placebo (n=15) in patients with type 2 diabetes mellitus. Participants are followed up for 7 days after treatment cessation.
Taking part does affect routine diabetes treatment or access to care. The study involves 8 hospital visits. Patients receive either tablets containing the test drug or tablets which do not contain the test drug (dummy). These are given in a random way and neither patients nor the research team will know which tablets were provided until the end of the study. The tablets containing the drug AZD4017 blocks the enzyme to lower cortisol levels. AZD4017 has already been studied in human volunteers and is safe and well tolerated at the dose and duration in this study. Participants are asked to attend a short screening visit to check heart function, blood pressure and blood tests. Participants who pass screening will be enrolled into the trial. They are asked to provide two 24 hour urine samples, four blood samples and five skin biopsies (two at one visit and three at another visit). Skin biopsies are taken from the arm after numbing the area with an injection. They are smaller than a ballpoint pen lid hole, do not require stitches and will not leave a noticeable scar. Participants are also measured for skin thickness, water loss, water content and nerve function using pain-free probes. Weight, height, blood pressure, waist and hip circumference are also recorded.
Primary outcome measure
11β-HSD1 activity in skin measured by evaluating conversion of radiolabelled 11β-HSD1 substrate (cortisone) to 11β-HSD1 product (cortisol) at baseline and day 28.
Secondary outcome measures
1. Systemic 11β-HSD1 activity is measured by evaluating tetrahydrocortisol to tetrahydrocortisone urinary metabolites ratios at baseline and day 35
2. AZD4017 in plasma and skin is measured by pharmacokinetic analysis at day 28
3. Adverse Event-related participant withdrawals (safety) will be measured by reviewing patient notes at day 42
