Combination of angiotensin II type 1 receptor antagonist and ACE inhibitor
The present invention relates to the use of an angiotensin II type 1 receptor antagonist and an ACE inhibitor for the prevention of non-fatal myocardial infarction.
A "combination" according to the invention may be present as a "fix combination" or as a "kit of parts combination".
A "fix combination" is defined as a combination wherein the angiotensin II type 1 receptor antagonist and the ACE inhibitor are present in one unit. One example of a "fix combination" is a pharmaceutical composition wherein the angiotensin II type 1 receptor antagonist and the ACE inhibitor are present in admixture, such as in a formulation. Another example of a "fix combination" is a pharmaceutical combination wherein the angiotensin II type 1 receptor antagonist and the ACE inhibitor are present in one unit without being in admixture.
A "kit of parts combination" is defined as a combination wherein the angiotensin II type 1 receptor antagonist and the ACE inhibitor are present in more than one unit. One example of a "kit of parts combination" is a combination wherein the angiotensin IT type 1 receptor antagonist and the ACE inhibitor are present separately. The components of the "kit of parts combination" may be administered simultaneously, sequentially or separately, i.e. separately or together.
With the wording "prevention" as used herein, is meant that non-fatal myocardial infarction is prevented by administering an angiotensin II type 1 receptor antagonist and an ACE inhibitor. This means that the use of an angiotensin IT type 1 receptor antagonist and an ACE inhibitor, provides prevention of a not yet developed non-fatal myocardial infarction.
The adjuvants, diluents and carriers used in the pharmaceutical formulations of the present invention, may be conventional ones well known to the person skilled in the art. Examples of such adjuvants, diluents and carriers include substances used as binders, lubricants, fillers, disintegrants, pH regulants and thickeners as well as substances included for providing isotonic solutions.
The wording "daily dose" is defined so that the angiotensin II type 1 receptor antagonist and the ACE inhibitor may be given either as a unit dosage once daily, such as a tablet or a capsule, or alternatively the angiotensin IT type 1 receptor antagonist and the ACE inhibitor may be given twice daily. The daily dose of each of the angiotensin II type 1 receptor antagonist and the ACE inhibitor may vary within the dosage ranges mentioned, and depends on the patient's individual response to treatment.
A myocardial infarction is defined herein as the condition that occurs when an area of heart muscle dies or is permanently damaged because of an inadequate supply of oxygen to that area. In non-fatal myocardial infarction, this condition does not result in the death of the subject.
Examples
A parallel, placebo-controlled cinical study was performed.
The inclusion criteria for the study were: age > 18 years, NYHA functional class II-IV for > 4 weeks (if class IT, the patient must have been hospitalised for a cardiac reason in the previous 6 months), left ventricular ejection fraction (LVEF) < 40% (measured within the past 6 months) and treatment with an ACE inhibitor at a constant dose for >30 days. Investigators were also asked to state whether each patient was, in their opinion, on an optimum, individualised, dose of ACE inhibitor. The key exclusion criteria were serum creatinine > 265 μmol/L (> 3 mg/dL), serum potassium > 5.5 mmol/L, symptomatic hypotension and bilateral renal artery stenosis.
Patients were randomised to receive candesartan cilexetil or matching placebo which could be started at 4 or 8 mg once daily. Treatment was usually started at a dose of 4 mg once daily and the dose was doubled at two weekly intervals, as tolerated, according to a forced titration protocol with recommended monitoring of blood pressure, serum creatinine and potassium. The target dose was 32 mg once daily from 6 weeks onwards. After randomisation, patients were seen at 2, 4 and 6 weeks, at 6 months and, thereafter, at 4 monthly intervals until the end of the trial.
The primary outcome in the study was cardiovascular (CV) death or unplanned admission to hospital for the management of worsening CHF.
Statistical methods
The planned sample size of 2,500 patients was designed to provide approximately 80% power to detect an 16% relative reduction in the primary outcome. The analysis was carried out on an intention-to-teat basis and included all randomised patients. All major outcomes were analysed using a time to first event approach. The primary analysis used the log-rank test for comparing the time to event distributions. The hazard ratios were estimated, together with 95% confidence intervals. In addition, a Cox regression model
with treatment and other prospectively defined covariates was performed to adjust the hazard ratio for these pre-specified baseline factors which might influence the event rates. P-values were two-sided and values of less than 0.05 were considered significant.
Results
Of the 2548 patients enrolled, 1276 were randomised to candesartan and 1272 to placebo. The median duration of follow up was 41 months.
Enalapril, lisinopril, captopril and ramipril were the most commonly used ACE inhibitors, together accounting for 74% of all ACE inhibitors used. The mean daily doses of these in the candesartan group were 16.8, 17.7, 82.2 and 6.8 mg, respectively, and in the placebo group, 17.2, 17.7, 82.7 and 7.3 mg, respectively. Investigators stated that they thought 96% of patients in each group were on an optimum, individualised, dose of ACE inhibitor at randomisation.
483 (37.9%) patients in the candesartan group and 538 (42.3%) patients in the placebo group experienced the primary outcome of CV death or hospitalisation for CHF, representing a hazard ratio (HR) of 0.85 (95% CI 0.75, 0.96), p=0.011 unadjusted, p=0.010 covariate adjusted. The annualised event rates were 14.1% in the candesartan group and 16.6% in the placebo group.
49 patients in the placebo group experienced non-fatal myocardial infarction, whereas in the candesartan group only 26 experienced non-fatal myocardial infarction. Thus, the risk of non-fatal myocardial infarction was 48.8% (p=0.006) lower in the candesartan group than in the placebo group (see also figure 1, showing the proportion of patients with confirmed non-fatal myocardial infarction over time).
