Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it requires that you have been on a stable dose of anti-hypertensive medication for at least 3 months. If you are currently taking diuretic medications, you cannot participate in the trial.

What data supports the effectiveness of the drug for treating pediatric chronic kidney disease?

The research highlights that hypertension (high blood pressure) is a common issue in children with chronic kidney disease and is linked to worsening kidney function and increased cardiovascular risk. While the studies emphasize the importance of controlling blood pressure, they also indicate that current treatments, including antihypertensive drugs, are not fully effective, as many children still have uncontrolled hypertension.12345

Is chronotherapy for pediatric chronic kidney disease safe for children?

The safety of blood pressure medications, which are often used in treating children with chronic kidney disease, is generally supported by their widespread use in managing hypertension (high blood pressure) in both children and adults. These medications, including thiazide diuretics, ACE inhibitors, and beta-blockers, are considered effective and safe for children when dosages are carefully adjusted based on weight.12346

How does the timing of blood pressure medication affect children with chronic kidney disease?

This treatment is unique because it focuses on the timing of taking blood pressure medication, known as chronotherapy, which aims to align medication administration with the body's natural rhythms to improve blood pressure control and potentially reduce kidney damage in children with chronic kidney disease.12347

What is the purpose of this trial?

This is a pilot, crossover trial in which the investigator will determine if retiming of one anti-hypertensive medication from morning to evening can effectuate normal blood pressure dipping patterns in children and adolescents with chronic kidney disease.

Eligibility Criteria

This trial is for children and adolescents up to 18 years old with chronic kidney disease (CKD) and high blood pressure, who have been on a stable dose of anti-hypertensive medication for at least three months. They must show abnormal blood pressure patterns overnight and have an eGFR between 30-90 ml/min/1.73 m2. Kids under six or those unable to complete necessary tests, on diuretics, with a history of organ transplant, cancer, or dialysis are excluded.

Inclusion Criteria

I am under 18 and have chronic kidney disease.
Your blood pressure does not decrease during sleep, as shown by a special test called ABPM.
I have been on the same blood pressure medication for at least 3 months.

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants are randomized to either remain on their current regimen or switch to nighttime dosing of one anti-hypertensive medication. ABPM is obtained after 1 week and at 1 month.

Treatment Details

Interventions

  • Current regimen
  • Re-timing of anti-hypertensive drug
Trial Overview The study is testing if changing the time when one anti-hypertensive drug is taken from morning to evening can help normalize blood pressure during sleep in kids with CKD. It's a pilot crossover trial meaning each participant will receive both treatments in sequence over different periods.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: nighttime dosing of one anti-hypertensive medicationExperimental Treatment1 Intervention
13 participants will be randomized to nighttime dosing of one anti-hypertensive medication. After 1 week, a repeat ABPM will be obtained. At 1 month from randomization, another ABPM will be obtained. Following this, there will be a 2-week washout period, during which all subjects will be on their usual anti-hypertensive regimen. A repeat ABPM will be obtained after the washout period. Next, the subjects will crossover to the opposite arm and an ABPM will be obtained after 1 week. A final ABPM will be obtained at 1 month after crossover.
Group II: remain on their current regimenActive Control1 Intervention
13 participants will be randomized to remain on their current regimen. After 1 week, a repeat ABPM will be obtained. At 1 month from randomization, another ABPM will be obtained. Following this, there will be a 2-week washout period, during which all subjects will be on their usual anti-hypertensive regimen. A repeat ABPM will be obtained after the washout period. Next, the subjects will crossover to the opposite arm and an ABPM will be obtained after 1 week. A final ABPM will be obtained at 1 month after crossover.

Findings from Research

In a study of 32 children with end-stage renal failure and chronic hypertension, 84.62% of those on chronic hemodialysis exhibited a blunted circadian blood pressure rhythm, indicating potential risks for end-organ damage.
Blood pressure measurements taken before and after dialysis were found to be reliable indicators of average blood pressure between dialysis sessions, correlating strongly with left ventricular mass index, which is important for assessing heart health in these patients.

Children with chronic kidney disease are at a significantly higher risk for cardiovascular issues, with those in end-stage renal disease facing a 30 times greater risk of cardiovascular mortality compared to healthy children.
Ambulatory blood pressure monitoring has shown a higher prevalence of abnormal blood pressure readings in children with chronic kidney disease and is better at predicting cardiovascular risk than traditional blood pressure measurements, as supported by large multi-center studies in Europe and North America.
Hypertension in chronic kidney disease: role of ambulatory blood pressure monitoring.VanDeVoorde, RG., Mitsnefes, MM.[2023]
A study of 851 children with chronic kidney disease (CKD) showed no significant improvement in casual blood pressure control between two time periods (2005-2008 and 2010-2013), indicating ongoing challenges in managing hypertension in this population.
However, the analysis revealed a concerning increase in masked hypertension and higher average sleep blood pressure indices in the later period, highlighting the need for better recognition and treatment of hypertension in children with CKD.
