About this study

Official title: Dose Prediction for Statins and Anticoagulant Medications in Cirrhotic Patients Using Simcyp Program: Applications in Clinical Practice

This prospective open-label parallel pilot clinical study evaluated the efficacy and safety of physiologically based pharmacokinetic (PBPK)-guided simvastatin dosing in Child-Pugh A and B cirrhotic patients with portal hypertension over a 3-month period. Twenty-two patients were enrolled following screening, and portal hemodynamic, laboratory, and safety parameters were assessed.

Read the detailed description

This was a prospective, open-label, parallel interventional clinical study conducted over a three-month period in Egyptian cirrhotic patients with portal hypertension.

Thirty patients were screened for eligibility. Eight patients were excluded as they did not meet the predefined inclusion criteria. A total of 22 patients were enrolled and completed the study.

Adult patients aged ≥18 years with confirmed liver cirrhosis and portal hypertension without a history of variceal bleeding were eligible for inclusion. Patients with severe renal impairment, pregnancy, known hypersensitivity to statins, active malignancy within the previous two years, or recent use of strong CYP3A4 inhibitors were excluded.

Patients were stratified according to Child-Pugh (CP) classification into CP class A and CP class B groups. Simvastatin doses were determined using physiologically based pharmacokinetic (PBPK) modeling via the Simcyp® Simulator to account for hepatic impairment-related changes in drug exposure.

CP class A patients received simvastatin 15 mg once daily, while CP class B patients received simvastatin 5 mg once daily.

Clinical evaluation included Doppler ultrasonographic assessment of portal and hepatic hemodynamics, including portal vein diameter, portal vein velocity, congestion index, and hepatic artery resistive index. Laboratory investigations included liver function tests (ALT, AST, total bilirubin, and serum albumin), renal function tests (serum creatinine and BUN), complete blood count, and creatine kinase for safety monitoring.

Patients were followed monthly throughout the 3-month study period, with systematic documentation of adverse events.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Simvastatin 15 mgDrug

    Simvastatin is an HMG-CoA reductase inhibitor that improves endothelial nitric oxide bioavailability and reduces intrahepatic vascular resistance, thereby potentially lowering portal pressure.

  • Simvastatin 5 mgDrug

    Simvastatin is an HMG-CoA reductase inhibitor that improves endothelial nitric oxide bioavailability and reduces intrahepatic vascular resistance, thereby potentially lowering portal pressure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Portal Vein Diameter (mm)

    Portal vein diameter will be measured as a Doppler ultrasound parameter to evaluate changes related to portal hypertension

    Measured: 3 months

  2. Change in Portal Vein Velocity (cm/s)

    Portal vein velocity will be assessed as an indicator reflecting changes in portal hypertension

    Measured: 3 months

  3. Change in Hepatic Artery Resistance Index (HARI)

    The Hepatic Artery Resistance Index will be measured as a Doppler-based marker associated with changes in portal hypertension

    Measured: 3 months

  4. Change in Congestion Index (CI) (cm/ [cm/s2])

    The congestion index will be evaluated as a Doppler-derived surrogate marker for portal hypertension severity

    Measured: 3 months

  5. Change in Modified Vascular Liver Index (MVLI) (cm/s)

    MVLI will be measured as part of the Doppler assessment reflecting changes in portal hypertension

    Measured: 3 months

  6. Change in Platelet Count (×10⁹/L)

    Platelet count will be assessed as a hematologic surrogate marker associated with portal hypertension.

    Measured: 3 months

Secondary outcomes (1)
  1. Incidence of adverse effects related to Simvastatin

    Adverse effects will be monitored throughout the study period, including clinical evaluation and laboratory investigations such as liver function tests (ALT, AST), creatine kinase (CK), and documentation of any muscle-related or gastrointestinal symptoms.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Simvastatin 15 mg and Simvastatin 5 mg in people with Liver Cirrhosis and Portal Hypertension Related to Cirrhosis, run by Kafrelsheikh University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Portal Vein Diameter (mm) (time frame: 3 months). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07459972, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2026.
