Plain English Summary
Background and study aims:
People with type 2 diabetes mellitus may develop kidney failure after a period of time. Albuminuria is the presence of a type of protein (called albumin) in the urine, and may also be a sign of kidney failure. Although the cause of this type of kidney injury is not fully known, the immune system appears to contribute. CCX140-B is a new drug which may prevent certain immune system cells from damaging the kidneys.
This study will test whether albumin levels can be reduced in people with type 2 diabetes mellitus. In this study CCX140-B is an additional therapy; it does not replace the standard treatment for kidney failure or type 2 diabetes mellitus.
Who can participate?
Men and women ages 18 to 75 years with diagnosed type 2 diabetes mellitus, with evidence of some kidney injury.
What does the study involve?
Half of the participants will receive 4 capsules of CCX140-B every day for 12 weeks, and the other half will receive 4 capsules without any drug every day for 12 weeks.
What are the possible benefits and risks of participating?
CCX140-B may be able to prevent kidney damage in future patients who have type 2 diabetes mellitus. Side effects of CCX140-B were mild in nature, however all investigational new drugs have the potential for unanticipated serious or life-threatening side effects.
Where is the study run from?
Centre for Human Drug Research, the Netherlands

Study information
Scientific title
A randomized, double-blind, placebo-controlled phase 2 study to evaluate the effect of CCX140-B on albuminuria in subjects with type 2 diabetes mellitus
Acronym
Study hypothesis
The rationale for this study is to investigate whether CCX140-B treatment of subjects with type 2 diabetes mellitus (T2DM) and albuminuria can reduce albuminuria. Because CCX140-B blocks the monocyte / macrophage migration from blood to tissues that occurs only during inflammation, it is anticipated that administration of CCX140-B will provide selective therapeutic benefit without compromising general immune surveillance.
