General information about the trial
|
|||
Main objective of the trial |
The primary objective was to evaluate the long-term safety and tolerability of Fixed Dose Combination (FDC) of Nifedipine Gastrointestinal Therapeutic System (GITS) / candesartan cilexetil (primarily the highest dose) once daily in subjects with moderate to severe essential hypertension.
|
||
Protection of trial subjects |
The conduct of this clinical study met all local legal and regulatory requirements. The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and the International Conference on Harmonization guideline E6: Good Clinical Practice. Before entering the study, the informed consent form was read by and explained to all subjects. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.

Screening details |
Of 753 subjects screened, 245 subjects were not enrolled, due to screen failure for 215 subjects, consent withdrawal by 23 subjects, protocol violation by 5 subjects, 1 subject was lost to follow-up and recruitment stopped for 1 subject. Remaining 508 subjects were enrolled and received at least 1 treatment with study drug. | ||||||||||||||||||||||||||||||

Arm description |
Subjects received nifedipine GITS/candesartan cilexetil FDC (BAY98-7106) tablet orally, once daily in the morning of Visit 1 (Week 0) for 28 or 52 weeks. The starting dose (30/8 milligram [mg] or 30/16 mg) was determined based on local practice and clinical judgment by the investigator. Based on the experience of symptomatic and asymptomatic hypotension, peripheral edema or significant tolerability, the doses were up-titrated to the highest target dose (60/32 mg). | ||||||||||||||||||||||||||||||

| Notes [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left. Justification: As planned, only the first 200 subjects who completed Week 28 visit, continued treatment up to 52 weeks. Hence, the number of subjects at this milestone seems inconsistent with the number of subjects in the arm. [2] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left. Justification: Of the first 200 subjects who entered Week 52 visit, 193 completed and the remaining 7 subjects did not complete due to consent withdrawal by 2 subjects, 1 subject lost to follow up and 4 subjects due to other reasons. Hence, the number of subjects at this milestone seems inconsistent with the number of subjects in the arm. |
