About this study

Official title: Vonoprazan vs. Pantoprazole in the Prevention of Post Endoscopic Band Ligation Ulcer/Bleeding in Portal Hypertensive Patients: A Randomized Controlled Trial

Endoscopic variceal ligation (EVL) is used to control and prevent variceal bleeding in patients with liver cirrhosis, but it can be complicated by bleeding from post-EVL ulcers. the current study aims at evaluating the potential benefit of different acid-suppressive therapies in prevention of post band ligation ulcer/bleeding. We will include 234 patients with cirrhotic portal hypertension undergoing endoscopic band ligation. Patients will be randomly allocated into one group of acid suppressive therapy (Vonoprazan or pantoprazole) versus placebo for 14 days. Re-endoscopy will be done after 2 weeks of treatment to assess the healing of post ligation ulcers. Any form of upper gastrointestinal bleeding will be documented.

Read the detailed description

Patients with portal hypertension who have esophageal varices usually are treated by endoscopic band ligation according to the international guidelines to prevent variceal bleeding. After band ligation, patients may suffer from post-ligation ulcer and/or bleeding. In the current study, we evaluate the effectiveness of Vonoprazan, a novel potassium-competitive acid suppressor agent, in prevention of post-ligation ulcer and /or bleeding. We also will compare this drug with the proton-pump inhibitor Pantoprazole and with placebo. We aim to enroll 234 patients who will undergo elective endoscopic variceal ligation according to the BAVINO VII guidelines will be randomly assigned to one of three arms : Vonoprazan 20 mg once daily, Pantoprazole 40 mg once daily, or Placebo (no treatment). The treatment will start from the day of band ligation and will continue for 14 days. After that, a follow up endoscopy will be done to evaluate the site of band ligation. Any ulcer at the ligation site will be documented and its size will be measured. Also, any attack of bleeding from the ulcer site (if present) will be documented. A comparison between the three arms will be done in terms of effectiveness, and bleeding rates.

Safety assessment:

The safety assessment will include all patients who will receive at least 1 dose of their assigned treatment. The safety endpoints will include treatment related adverse effects (TRAEs) grouped by Medical Dictionary for Regulatory Activities version 19.1, system organ class and preferred term, and changes from baseline in an abbreviated physical examination including vital signs, signs of liver cell deterioration, and mean change in laboratory measures including hemogram, liver aminotransferases, serum urea and creatinine, liver function test.

What is being measured

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

  1. Post ligation ulcer : presence (Yes or No), number, and size

    1. presence of post ligation ulcer (Yes/NO)
    2. the number of ulcers if present.
    3. the maximum dimension of an ulcer (if present) in millimeter.

    Measured: At 2 weeks after intervention (EBL)

  2. Post endoscopic variceal ligation ulcers

    Number of participants who experienced post-ligation ulcer.

    Measured: At 2 weeks after intervention

  3. Post endoscopic variceal ligation bleeding

    Number of participants who experienced post-ligation ulcer bleeding.

    Measured: during the 2 weeks treatment duration

Secondary outcomes (1)
  1. Number of participants with Vonoprazan-related adverse events as assessed by TRAEs grouped by Medical Dictionary for Regulatory Activities version 19.1

    • The safety assessment will include all patients who will receive at least 1 dose of their assigned treatment.
    • The safety endpoints will include treatment related adverse effects (TRAEs) grouped by Medical Dictionary for Regulatory Activities version 19.1, system organ class and preferred term, and changes from baseline in an abbreviated physical examination and laboratory parameters including:
    • Vital signs,
    • New onset hepatic encephalopathy,
    • New onset ascites OR Increasing a pre-existing ascites,
    • Changes in hemogram,
    • Liver aminotransferases,
    • Prothrombin time/INR
    • Serum Bilirubin
    • Serum urea and creatinine.

    These data will be collected through:

    • Recording the baseline clinico-laboratory parameters at the 1st visit
    • Re-evaluation of the same parameters at 2 weeks follow-up visit
    • Encouraging the patients to communication with the study team in case of any other adverse events that may occur during the treatment duration.

    Measured: During the 2 weeks of medication use

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 3 inclusion and 9 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 30 Aug 2024. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Post ligation ulcer : presence (Yes or No), number, and size (time frame: At 2 weeks after intervention (EBL)). The study lists 3 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 NCT05227833, which also lists 2 linked publications.

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 30 Aug 2024; AzTrials last refreshed its copy on 7 Nov 2026.
