About this study

Official title: Clinical Study to Evaluate the Possible Efficacy and Safety of Mebendazole in Patients With Ulcerative Colitis Treated With Mesalamine

To evaluate the possible efficacy and safety of mebendazole in patients with ulcerative colitis treated with mesalamine

Read the detailed description

A randomized, controlled, and parallel study will comprise 46 patients with UC. Patients will be recruited from GastroEnterology Department, Mansoura University Hospital.

The participants will be randomly assigned into two groups as follow:

Group 1: control group (Mesalamine group, n =23) who will receive 1 g mesalamine three times daily for 6 months.

Group 2: (mebendazole group, n = 23) which will receive the standard treatment for UC plus mebendazole 500 mg twice daily for 6 months.

What is being measured

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

  1. change in disease activity

    Disease severity which will be assessed according to the modified Truelove and Witt's classification based on number of bloody stools per day plus one or more of 4 additional criteria including pulse, temperature, hemoglobin and Erythrocyte sedimentation rate (ESR) . Remission will be defined as disappearance or improvement of symptoms such as normal stool and stooling pattern without blood, no fever, no tachycardia, hemoglobin level normal or returning toward normal, ESR normal or returning toward normal, and patient gaining weight.

    Measured: change in baseline

  2. change in Partial Mayo Scoring Index (PMSI) assessment for Ulcerative Colitis Activity

    depends on three items; stool frequency, rectal bleeding (blood in stool) and Physician's Global Assessment. Each item has a score from 0 to 3 and total PMSI is the sum of scores for the three items.

    Remission is defined as total PMSI = 0-1, mild disease is defined as total PMSI = 2-4, moderate disease is defined as total PMSI = 5-6 and severe disease is defined as total PMSI =7-9.

    Measured: change in baseline

Secondary outcomes (6)
  1. Change in Hemoglobin Concentration

    Enzyme-linked immunosorbent assay (ELISA)

    Measured: Blood samples will be taken from all patients at baseline then six months of therapy

  2. Change in Erythrocyte sedimentation rate (ESR)

    Enzyme-linked immunosorbent assay (ELISA)

    Measured: Blood samples will be taken from all patients at baseline then six months of therapy

  3. Change in Serum albumin

    Enzyme-linked immunosorbent assay (ELISA)

    Measured: Blood samples will be taken from all patients at baseline then six months of therapy

  4. Change in Serum Interleukin -6 (IL-6)

    Enzyme-linked immunosorbent assay (ELISA)

    Measured: Blood samples will be taken from all patients at baseline then six months of therapy

  5. Change in Serum Nitric oxide (NO)

    Enzyme-linked immunosorbent assay (ELISA)

    Measured: Blood samples will be taken from all patients at baseline then six months of therapy

  6. Change in Serum Intra cellular adhesion molecule 1 (ICAM-1)

    Enzyme-linked immunosorbent assay (ELISA)

    Measured: Blood samples will be taken from all patients at baseline then six months of therapy

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 1 inclusion and 22 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: looking for participants now, as of the sponsor's last update on 6 Feb 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change in disease activity (time frame: change in baseline). The study lists 2 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 NCT06335160, which also lists 15 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.
