Arms Assigned Interventions
Placebo Comparator: Placebo (Group A) Drug: Placebo
Placebo capsules once daily
Experimental: CCX140-B (Group B) Drug: CCX140-B

Detailed Description:

The primary objective of this study is to evaluate the safety and tolerability of CCX140-B in subjects with diabetic nephropathy based on subject incidence of adverse events.

The secondary objectives of this study include evaluation of the effect of CCX140-B on several measures of effectiveness commonly used in the evaluation of diabetes and renal medications.


Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Key Inclusion Criteria:

  • Aged 18-75 years inclusive, with documented previously diagnosed type 2 diabetes mellitus (per American Diabetes Association [ADA] criteria)
  • Residual albuminuria despite stable treatment with an angiotensin-converting enzyme (ACE) inhibitor or an angiotensin receptor blocker (ARB) for at least 8 weeks prior to screening (Albumin:creatinine ratio [ACR] of 100 to 3000 mg/g creatinine, inclusive)
  • Estimated glomerular filtration rate based on serum creatinine (eGFR, determined by Modification of Diet in Renal Disease [MDRD] equation) of ≥ 25 mL/min/1.73 m(2)
  • Must be on a stable dose of an ACE inhibitor or ARB for at least 8 weeks prior to screening, but subjects must not be on both an ACE inhibitor and an ARB
  • Hemoglobin A1c (HbA1c) > 6.0% but not > 10.0% and fasting plasma glucose less than 270 mg/dL at screening

Key Exclusion Criteria:

  • Type 1 diabetes mellitus or history of diabetic ketoacidosis
  • Previous renal transplant or known non-diabetic renal disease, except related to hypertension
  • Undergone renal dialysis at any time in the past
  • Received chronic (more than 7 days continuously) systemic glucocorticoid or other immunosuppressive treatment within 8 weeks of screening
  • Use of bardoxolone, atrasentan or other endothelin antagonist within 8 weeks of screening
  • Received chronic (more than 7 days continuously) non-steroidal anti-inflammatory drug (NSAID) treatment within 2 weeks of screening
  • Cardiac failure (class III or IV), history of unstable angina, symptomatic coronary artery disease, myocardial infarction or stroke within 12 weeks of screening
  • Poorly-controlled blood pressure (systolic blood pressure >155 or diastolic blood pressure >95, with blood pressure measured in the seated position after at least 5 minutes of rest)
