Study summary

This clinical trial with 328 patients with primary hypertension aims to investigate the effectiveness of the self-guided digital application liebria for patients with primary hypertension.

Read the detailed description

This clinical trial with 328 patients with primary hypertension aims to investigate the effectiveness of the self-guided digital application liebria for patients with primary hypertension. Inclusion criteria are: age ≥ 18; presence of primary hypertension (confirmed by medical certificate or equivalent); unmedicated or with existing antihypertensive drug therapy (with stable dose in the past 6 weeks prior to study enrolment); last reported office-based systolic blood pressure (SBP) ≥ 140 mmHg followed by home-based SBP ≥ 135 mmHg; consent to participate. Exclusion criteria are: home-based SBP > 180 mmHg; > triple combination of antihypertensive medication; history of secondary hypertension (e.g., thyroid disease, kidney disease); pregnancy.

Patients will be randomized and allocated in a 1:1 ratio to either an intervention group, in which they will receive access to liebria in addition to treatment as usual (TAU, n = 164), or to a control group, in which they will receive a relevant brochure from the Deutsche Hochdruckliga (German Hypertension League) in addition to TAU (n = 164). TAU is defined as any therapy prescribed or recommended by the GP or specialists (e. g. cardiologist).

The primary endpoint will be home-based SBP, with 6 months post-allocation being the primary time point for assessment of effectiveness. Three months post-allocation will be used as an additional endpoint. Secondary endpoints will be patient activation, social and work-related functioning, medication adherence, home-based diastolic blood pressure (DBP), and pulse pressure.

Analysis of effectiveness of the intervention will be performed by ANCOVA of the primary endpoint and all secondary endpoints, in which the posttreatment scores will be compared between treatment groups (intervention group vs. control group), using the baseline scores of the respective outcome as a covariate.

Study arms

  • Experimental
    liebria

    Participants allocated to the intervention group will receive access to liebria in addition to treatment as usual (TAU). reviga is a digital health application designed for individuals with hypertension, accessible through a web browser. The application focuses on evidence-based psychological and psychotherapeutic methods combined with psychoeducation and health behavior change. Topics addressed by liebria include clarifying and strengthening motivation, training the parasympathetic nervous system, recognizing and overcoming obstacles, strengthening impulse control, development of an individualized day plan, and relapse prevention. The program operates through interactive "dialogues", which are accompanied by illustrations, audio recordings, motivating text messages, worksheets, and summaries. Users are also encouraged to regularly complete short questionnaires to monitor their complaints. Once registered, the program remains accessible for 360 days.

What researchers measure

Primary outcomes

  1. SBP (in mmHg)

    The primary endpoint is SBP collected via home-based blood pressure measurement (HBPM) using a validated semi-automatic arm cuff device. HBPM will be performed according to the recommendations of the European Society of Hypertension.

    Time frame: 6 months

Secondary outcomes

  1. Patient activation

    Patient Activation Measure (PAM-13). Total score ranging from 0-100; higher scores mean higher activation (better outcome).

    Time frame: 6 months

    Work and Social Adjustment Scale (WSAS). Total score ranging from 0-40; higher scores mean higher impairment (worse outcome).

    Time frame: 6 months

  3. Adherence to medication

    Rief Adherence Index (RAI). Total score ranging from 4-20; higher scores mean higher non-adherence (worse outcome).

    Time frame: 6 months

  4. DBP (in mmHg)

    DBP is collected via home-based blood pressure measurement (HBPM) using a validated semi-automatic arm cuff device. HBPM will be performed according to the recommendations of the European Society of Hypertension.

    Time frame: 6 months

  5. Pulse pressure (in mmHg)

    Pulse pressure (PP) is collected via home-based blood pressure measurement (HBPM) using a validated semi-automatic arm cuff device. HBPM will be performed according to the recommendations of the European Society of Hypertension.

    Time frame: 6 months

Other outcomes

  1. Body Mass Index

    weight in kilograms and height in meters will be assessed and combined to report BMI in kg/m\^2

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 Apr 2024 (actual). Primary completion is estimated for Jun 2026, 26 months after the start.

Of 95 industry-sponsored interventional studies with no phase under Hypertension, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 55. This study's planned 26 months is below that.

Counting every sponsor, half of 1,498 studies reached it within 23 months; a quarter within 10 and three quarters within 41.

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 Jun 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
