Study summary

Previous studies have shown that elevated nighttime blood pressure (BP) was more closely associated with cardiovascular mortality and morbidity than daytime and clinic BPs. With increasingly advanced technology, not only 24-hour ambulatory but also home BP monitors can be used to evaluate nighttime BP. The validation study of the Omron HEM 9601T showed that the wrist-type home BP monitor could be a suitable and reliable tool for the diagnosis and management of nocturnal hypertension. However, up to now, there is no data on home nighttime BP in Chinese patients and it is unclear if different dosing time would reduce ambulatory and home nighttime BPs differently.

The investigators therefore designed a multicenter randomized clinical trial to compare between morning dosing and bedtime dosing of antihypertensive medications in the difference in nighttime, daytime and the 24-h BP reductions evaluated by both ambulatory and home BP monitoring, and in target organ protections.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Active comparator
    The morning dosing group

    After randomization, subjects will take alisartan 120 mg (Salubris, Shenzhen, China) once daily at 6:00-10:00. After 8 weeks of treatment, if the 24-hour ambulatory systolic BP remained ≥ 130 mmHg, alisartan will be doubled to 240mg. After 16 weeks of treatment, if the 24-hour ambulatory systolic BP remained ≥ 130 mmHg, amlodipine besylate 2.5 mg (Dawnrays, Suzhou, China) once daily will be added. The whole treatment duration will last for 24 weeks.

    Drug: Alisartan, Amlodipine besylate

  • Experimental
    The bedtime dosing group

    After randomization, subjects will take alisartan 120 mg once daily at 20:00-24:00. The follow-up plan is the same as the morning dosing group.

    Drug: Alisartan, Amlodipine besylate

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2021 (actual). Primary completion is estimated for Jun 2026, 65 months after the start.

Of 126 non-industry phase 4 interventional studies under Hypertension, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 54. This study's planned 65 months is above that.

Counting every sponsor, half of 161 studies reached it within 31 months; a quarter within 16 and three quarters within 52.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
