Plain English summary of protocol

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

When is the study starting and how long is it expected to run for?
Enrolment began in September 2011 and the study finished in June 2012.

Scientific titleA randomized, double-blind, placebo-controlled phase 2 study to evaluate the effect of CCX140-B on albuminuria in subjects with type 2 diabetes mellitus
Study objectivesThe 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.
