Brief Summary:

The purpose of this study was to determine whether, in patients with type 2 diabetes and pre-existing disease of the heart and the circulatory system and/or the kidney, aliskiren at a target dose of 300 mg once daily (compared to placebo), on top of conventional treatment, reduces death and disease caused by the heart, the circulatory system and the kidney.

AMENDMENT 4 RATIONALE (MARCH 2012) :

Protocol amendment 4 served to address the data monitoring committee recommendation dated 14 Dec 2011 to discontinue study treatment in all participating patients. It also addressed the subsequent Health Authorities request to implement a 12 month safety follow-up period (actual duration was 9 months in average) post study drug discontinuation.

Arm Intervention/treatment
Experimental: Aliskiren

In Core (Double Blind) phase, Aliskiren 150 mg once daily (o.d.) for 4 weeks; then patient was uptitrated to 300 mg o.d. at Visit 5/Week 4 (or 150 mg o.d. if patient could not tolerate target dose of study drug). Visits took place at 1, 4 , 5, 8 and 12 weeks after randomization (Visit 3/Week 0). Subsequent visits were planned every three months until end of core phase.

With the recommendation of Data Monitoring Committee (DMC), after discontinuation of study drug, a follow up was added as Extension Phase (9 months in average) with no active treatment

 Drug: Aliskiren
Aliskiren 150 mg film-coated tablets
Placebo Comparator: Placebo

In Core (Double Blind) phase, placebo to match aliskiren 150 mg once daily (o.d.) for 4 weeks; from Visit 5/Week 4 placebo to match aliskiren 300 mg o.d. (or placebo to match aliskiren 150 mg if patient could not tolerate target dose of study drug). Visits took place 1, 4 , 5, 8 and 12 weeks after randomization (Visit 3/Week 0). Subsequent visits were planned every three months until end of core phase.

With the recommendation of Data Monitoring Committee (DMC), after discontinuation of study drug, a follow up was added as Extension Phase (9 months in average) with no active treatment.

Other Outcome Measures:
  1. Percentage of Participants With Angioedema/Angioedema-like or Colorectal Events (Core : Active Treatment Phase) [ Time Frame: Time from randomization to the first event (Maximum 50 months) ]
    AEs of special interest were reported according to a post-marketing commitment to Health Authorities and included angioedema/angioedema-like events and colorectal events/ procedures

  2. Change From Baseline in Urinary Albumin to Creatinine Ratio (UACR) to Month 6 and to Last Measurement (Core : Active Treatment Phase) [ Time Frame: Baseline, Month 6 , last measurement (maximum at 50 months) ]

    Baseline is the geometric mean of last 3 measurements before visit 3, Post-baseline value is the geometric mean of last 3 measurements during each visit.

  3. Mean Changes in Estimated Glomerular Filtration Rate (eGFR) From Baseline to Month 3 and Month 6 (Core : Active Treatment Phase) [ Time Frame: Baseline to Month 3 and Month 6 ]

    The eGFR calculation was based on the Abbreviated Modification of Diet in Renal Disease (MDRD) Study Equation. Using this method, the applicable MDRD formula to calculate eGFR was as follows:

    Estimated GFR (mL/min/1.73 m^2) = 175 x (serum creatinine in mg/dL) -1.154 x (Age in years) -0.203 x (0.742 if female) x (1.210 if Black)

    Mean changes in eGFR from baseline to month 3 and month 6 were included for analysis. The LS Mean and Standard Error were based on an ANCOVA repeated-measure model with treatment, visit, treatment-by-visit and baseline eGFR as effect terms.


  4. Percentage of Participants With Angioedema/Angioedema-like Events or Colorectal Events (Extension Phase) [ Time Frame: From cut-off date (20Dec2011/End of Treatment (EOT) ) to the first event after cut-off date (9 months in average) ]
    AEs of special interest were reported according to a post-marketing commitment to Health Authorities and included angioedema/angioedema-like events and colorectal events/ procedures.
