VITAL: Real-World Evaluation of Amlodipine/Valsartan. (VITAL)
Evaluation of Clinical Effectiveness in Real-World Clinical Practice, as Well as the Safety and Adherence to Therapy With a Fixed-Dose Combination of Amlodipine and Valsartan
The goal of this observational study is to evaluate the effectiveness, safety, and treatment adherence of a fixed-dose combination of amlodipine and valsartan in adults with grade 2-3 hypertension in real-world clinical practice in Kazakhstan. The study will include patients who have already been prescribed the fixed-dose combination of amlodipine and valsartan (Agvistat®) by their treating physician as part of routine medical care, independently of their participation in the study.
The main questions it aims to answer are:
What proportion of participants achieve the target blood pressure after 12 weeks of treatment with the fixed-dose combination of amlodipine and valsartan? How well do participants adhere to treatment, and what patient characteristics are associated with treatment adherence? What changes occur in blood pressure, heart rate, quality of life, and selected laboratory measures during the 12-week observation period? What adverse events occur during treatment?
Participants will:
Have their clinical and demographic information and data from routine medical care recorded during the study.
Have blood pressure, heart rate, and other relevant clinical data assessed during the 12-week observation period.
Complete questionnaires assessing treatment adherence and quality of life. Participate in follow-up visits at 4, 8, and 12 weeks; the 4- and 8-week visits will be conducted remotely, while the enrollment and 12-week visits will be conducted at the study site.

Метод выборки
Исследуемая популяция
The study population will consist of adult male and female patients aged ≥18 years with a confirmed diagnosis of grade 2-3 hypertension who have been prescribed a fixed-dose combination of amlodipine and valsartan (Agvistat®) by their treating physician as part of standard clinical practice, independently of participation in the study. The study will include patients with a medical history indicating failure to achieve target blood pressure while receiving a free combination of antihypertensive drugs. A total of 216 participants will be enrolled and observed for up to 12 weeks.

Amlodipine/valsartan-treated cohort
Adults with grade 2-3 hypertension who have been prescribed a fixed-dose combination of amlodipine and valsartan (Agvistat®) by their treating physician as part of routine clinical practice, independently of participation in the study. Participants are observed for up to 12 weeks to assess treatment effectiveness, adherence, safety, blood pressure control, and quality of life. |
Fixed-dose combination of amlodipine and valsartan administered as part of routine clinical practice. The treatment is prescribed by the treating physician independently of study participation. The study does not assign treatment or provide the study drug. The available doses are amlodipine 5 mg/valsartan 160 mg and amlodipine 10 mg/valsartan 160 mg, administered once daily. |
