This is a clinical study evaluating the superiority in efficacy and assess safety and tolerability of BAYA1040_Nifedipine 80 mg/day (40 mg twice daily) compared with BAYA1040_Nifedipine 40 mg/day (40 mg once daily) in patients with essential hypertension who are not at target blood pressure by BAYA1040_Nifedipine 40 mg once daily treatment.

Condition Intervention Phase
Hypertension Drug: Nifedipine (Adalat, BAYA1040) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment

Further study details as provided by Bayer:

Primary Outcome Measures:
  • Efficacy changes measured by sitting diastolic blood pressure (DBP) [ Time Frame: Up to 8 weeks ]

Secondary Outcome Measures:
  • Efficacy changes measured by sitting systolic blood pressure (SBP) [ Time Frame: Up to 8 weeks ]
  • Achievement rate: Proportion of subjects achieving a target BP based on the Japanese Society of Hypertension (JSH) 2009 guidelines [ Time Frame: Up to 8 weeks ]
  • Responder rate: Proportion of subjects achieving a target DBP and SBP based on JSH 2009 guidelines or a >10 mmHg reduction of DBP [ Time Frame: Up to 8 weeks ]
