Study summary

We assessed the influence of time of administration of ACE inhibitors on circadian blood pressure control in sub Saharan type 2 diabetes patients with stage 1 hypertension over 56 days as first line treatment.

Read the detailed description

Background: Renin-angiotensin system antagonists represent the mainstay of blood pressure (BP) lowering treatment options in people with diabetes. ACE inhibitors have a long half-life and offer the advantage of a single daily dose, usually empirically taken in the morning.

Objective: We assessed the influence of time of administration of ACE inhibitors on circadian BP control in type 2 diabetes (T2D) patients with stage 1 hypertension.

Methods: Twenty T2D patients (9 being women) with a mean age of 58.7 years, diagnosed with stage 1 of hypertension and naive to BP lowering medications, were included. They were randomly allocated to receive perindopril 10 mg/day as a monotherapy either in the morning or in the evening for 28 days, with crossover without washout period on day 29th and additional 28 days follow-up. A 24-hour ambulatory BP monitoring (ABPM) was performed at baseline, days 28 and 56.

Terms in these criteria, in plain language(2)

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.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

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

Ran from Feb 2016 to primary completion in Jul 2016, 5 months.

Of 320 non-industry phase 4 interventional studies under Diabetes Mellitus, Type 2, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 49. This study's 5 months is below that.

Counting every sponsor, half of 452 studies reached it within 24 months; a quarter within 13 and three quarters within 42.

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 8, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
