Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)

Primary Outcome Measures:
  • Urinary Albumin Excretion (µg/min) levels in the overnight urine specimen. [ Time Frame: 12 weeks ]
    Relative change (per cent change) in Urinary Albumin Excretion (UAE) from the baseline


Secondary Outcome Measures:
  • Urinary Monocyte Chemoattractant protein (MCP-1/CCL2)(pg/ml) levels in the overnight urine specimen. [ Time Frame: 12 weeks ]
    Relative change (per cent change) in Urinary MCP-1 levels from the baseline.

  • Serum lipids [ Time Frame: 12 weeks ]
    Relative change (per cent change) in total cholesterol, cholesterol HDL, triglycerides, apolipoprotein-A, apolipoprotein-B from the baseline.

  • Safety and tolerability of bindarit in association of irbesartan. [ Time Frame: 12 weeks ]
    Changes in anthropometrics, laboratory parameters and vital signs from the baseline. Number of adverse events.

  • Albuminuria remission rates [ Time Frame: 12 weeks ]
    Rate of remission from macro to microalbuminuria and from micro to normoalbuminuria.


Enrollment: 100
Study Start Date: March 2007
Study Completion Date: December 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bindarit
Patients treated with bindarit 2x300 mg bid plus irbesartan 2x150 mg once a day for 12 weeks
Drug: Bindarit
dosage form:tablet dosage:2x300 mg frequency:b.i.d duration:12 weeks
Other Name: AF2838
Placebo Comparator: Placebo
patients treated with placebo 2 tablets bid plus irbesartan 2x150 mg once a day for 12 weeks
Drug: Placebo
dosage form: tablet dosage: n.a. frequency: 2xplacebo b.i.d duration:12 weeks

Detailed Description:

This is a pilot phase II, double-blind, multicentre, randomized, placebo-controlled, parallel groups study in patients with DN undergoing irbesartan therapy.

According to screening urinary albumin excretion, at baseline and before randomization, all patients will be categorized into 2 strata:

Stratum 1: microalbuminuria (20 to 200 μg/min, in at least 2 of 3 consecutive overnight urine samples collected at the screening) Stratum 2: macroalbuminuria (>200 μg/min, in at least 2 of 3 consecutive overnight urine samples collected at the screening).

Within each stratum, patients will be randomly allocated on a 1:1 basis to the 2 treatment arms (after one month induction period):

  • bindarit 600MG twice a day
  • placebo All patients will be treated with irbesartan 300 mg/day as background therapy. After 12 months of treatment albuminuria will be evaluated as primary endopoint.
