Glucocorticoids and Skin Healing in Diabetes (GC-SHealD) (GC-SHealD)
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
연구 개요
상세 설명
Glucocorticoids are known to impair skin function and wound healing which are also compromised in patients with type 2 diabetes. The enzyme 11 beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1) activates glucocorticoids in target tissues including skin. Pre-clinical data demonstrate that 11β-HSD1 inhibition improves skin function and wound healing but this has not been investigated in man.
Using the 11β-HSD1 inhibitor AZD4017, we will investigate if
- Oral AZD4017 inhibits 11β-HSD1 activity in skin
- AZD4017 is safe and well-tolerated in patient with T2DM
- Oral AZD4017 regulates skin function
- Systemic glucocorticoid levels and skin 11β-HSD1 activity, independently or in combination correlate with measures of skin function
Study feasibility will also be assessed; if successful, data from this pilot study will inform power calculations for a future trial to investigate the ability of 11β-HSD1 inhibition to promote foot ulcer healing in type 2 diabetes.

활성 비교기: AZD4017
400mg oral AZD4017 twice daily for 35 days

AZD4017 is a novel orally bioavailable small molecule inhibitor of 11β-HSD1 enzyme activity.
It is potent and highly selective in vitro and in vivo.
The half maximal inhibitory concentration (IC50) for inhibition of 11β-HSD1 activity (cortisone to cortisol conversion) is 2nM.
AZD4017 is selective (> 2000x) for 11β-HSD1 over human recombinant 11β-HSD2 and the closely-homologous enzymes 17β-hydroxysteroid dehydrogenase 1 and 17β-hydroxysteroid dehydrogenase 3 in vitro.
