  4. Mean seated Systolic Blood Pressure (SBP) =180 mm Hg and/or mean seated Diastolic Blood Pressure (DBP) =110 mm Hg during any visit of the screening and placebo run-in periods

  5. Patients with Type 1 diabetes mellitus

  6. Renal dysfunction as defined by the following laboratory parameters: Serum creatinine >3.0 mg/dL (or >265 µmol /L) or known creatinine clearance <30 mL/min or clinical markers of severe renal impairment

  7. Bilateral renal artery stenosis, renal artery stenosis in a solitary kidney, post-renal transplant patients or patients with only one kidney

  8. Clinically relevant hypokalaemia or hyperkalaemia

  9. Uncorrected sodium or volume depletion

  10. Primary aldosteronism

  11. Hereditary fructose intolerance

  12. Biliary obstructive disorders (e.g., cholestatis) or hepatic insufficiency

  13. Congestive heart failure New York Heart Academy (NYHA) functional class CHF III-IV (Refer to Appendix 10.3)

  14. Contraindication to a placebo run-in period (e.g., stroke with-in the past six months, myocardial infarction, cardiac surgery, percutaneous transluminal coronary angioplasty, unstable angina or coronary artery bypass graft within the past three months prior to start of run-in period)

  15. Clinically significant ventricular tachycardia, atrial fibrillation, atrial flutter or other clinically relevant cardiac arrhythmias as determined by the Investigator

  16. Hypertrophic obstructive cardiomyopathy, severe obstructive coronary artery disease, aortic stenosis, hemodynamically relevant stenosis of the aortic or mitral valve

  17. Patients whose diabetes has not been stable and controlled for at least the past three months as defined by an HbA1C >10%

  18. Patients who have previously experienced symptoms characteristic of angioedema during treatment with Angiotensin Converting Enzyme (ACE) inhibitors or angiotensin-II receptor antagonists

  19. History of drug or alcohol dependency within six months prior to signing the informed consent form

  20. Concomitant administration of any medications known to affect blood pressure, except medications allowed by the protocol

  21. Any investigational drug therapy within one month of signing the informed consent

  22. Known hypersensitivity to any component of the study drugs (telmisartan, amlodipine, or placebo)

  23. History of non-compliance or inability to comply with prescribed medications or protocol procedures

  24. Any other clinical condition which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of telmisartan and amlodipine
