Aliskiren Trial in Type 2 Diabetes Using Cardiovascular and Renal Disease Endpoints (Core and Extension Phases) - Full Text View

Purpose

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.

Primary Outcome Measures:

Percentage of Participants With Occurrence of Primary Composite Endpoint (Core : Active Treatment Phase) [ Time Frame: Time from randomization to the first event (Maximum 50 months) ] [ Designated as safety issue: No ]
Occurrence was defined as the first event of the following composite primary endpoint:
- Cardiovascular (CV) death
- Resuscitated sudden death
- Non-fatal myocardial infarction (MI)
- Non-fatal stroke
- Unplanned hospitalization for heart failure (HF)
- Onset of end-stage renal disease (ESRD) or death due to renal failure. Onset of ESRD was defined as initiation of dialysis, renal transplantation, or a serum creatinine concentration above 6.0 mg/dL (530 μmol/L), sustained for at least a month.
- Doubling of baseline serum creatinine concentration, sustained for at least one month. To fulfill the endpoint, the serum creatinine concentration had to be above the upper limit of normal for men and women according to the central laboratory. The upper limit of normal for men is 1.20 mg/dL and for women is 0.91 mg/dL.
Percentage of Participants With Cardiovascular (CV) Death (Core: Active Treatment Phase) [ Time Frame: Time from randomization to the first event (Maximum 50 months) ] [ Designated as safety issue: No ]
Percentage of Participants With Resuscitated Sudden Death (Core: Active Treatment Phase) [ Time Frame: Time from randomization to the first event (Maximum 50 Months) ] [ Designated as safety issue: No ]
Resuscitated sudden death was adjudicated when a subject experiences sudden death or cardiac arrest and is successfully resuscitated by cardioversion, defibrillation or cardiopulmonary resuscitation with a meaningful recovery of consciousness. This definition excludes known transient losses of consciousness such as seizure or vasovagal episodes that do not reflect significant cardiac dysfunction.

Other Outcome Measures:

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) ] [ Designated as safety issue: Yes ]
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
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) ] [ Designated as safety issue: No ]
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.

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 ] [ Designated as safety issue: No ]
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.
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) ] [ Designated as safety issue: Yes ]
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.
