Azilsartan Medoxomil Study in Hypertensive Children
A Comparative Single-Dose Pharmacokinetic and Safety Study of TAK-491 Between Infants, Children, and Adolescents With Hypertension and Healthy Adults

The purpose of this study is to assess the pharmacokinetics and safety of azilsartan medoxomil in pediatric subjects who have hypertension and healthy adult subjects.

Within the past 10 years, the incidence of high blood pressure (hypertension) in children and adolescents has increased all over the world. This increase is connected in part to a growing number of people who are overweight and do not eat right or exercise enough.

This study looked at a blood pressure medicine called TAK-491 (azilsartan medoxomil) to see how it works in children who have hypertension. Azilsartan medoxomil is a prodrug that converts into TAK-536 (azilsartan), another untested blood pressure medicine. Adults who do not have hypertension also took part in this study to provide a comparison.

To be eligible to take part in this study, children must have been between the ages of 1 year and 16 years old, and had to stop taking their current antihypertensive medication for one day prior to the start of this study. Each child was given one dose of azilsartan medoxomil, followed by a number of blood tests and assessments within 24 hours after taking azilsartan medoxomil to see how the medication is working.

This study took place in approximately 10 sites in the UK and USA. A total of approximately 20 children with hypertension and approximately 9 adults without hypertension participated in this study.

This study lasted about 43 days. This included a 28 day screening period, a 2 day treatment phase and a follow up period. Each person taking part in this study may have been requested to remain in a hospital for one overnight stay during the course of the study. Each participant was contacted by telephone 6 days and 15 days after taking azilsartan medoxomil.

Takeda has decided to close Cohort 3 (subjects between 1 and 6 years of age with hypertension) enrollment early and end this study with the agreement of both the US Food and Drug Administration (FDA) and the Pediatric Committee (PDCO) at the European Medicines Agency. Requests to the FDA and PDCO were submitted to close the study without completion of enrollment in Cohort 3 due to difficulty enrolling this particular patient population. Takeda proposed an alternative option to collect PK data in this age subset by utilizing PK modeling to determine the appropriate doses in children 1-5 years of age in lieu of completing Cohort 3. The FDA and PDCO agreed with this approach
