About this study

Official title: Effect of Levamisole Supplementation on Tetanus Vaccination Response Rates in Hemodialysis Patients: A Randomized Double-Blind Placebo-Controlled Trial

Levamisole as an immunomodulator drug has been demonstrated to improve the immune response to Hepatitis B virus (HBV) vaccination in hemodialysis patients. The aim of this study was to evaluate the effect of levamisole supplementation on tetanus-diphtheria (Td) vaccine response rate in hemodialysis patients.

Read the detailed description

Levamisole as an immunomodulator drug has been demonstrated to improve the immune response to HBV vaccination in hemodialysis patients. The aim of this study was to evaluate the effect of levamisole supplementation on Td vaccine response rate in hemodialysis patients. In this randomized double-blind placebo-controlled trial 40 hemodialysis patients who had not received tetanus vaccination in a year before investigation and had unprotective anti-tetanus immunoglobulin G (IgG) levels (<0.1 International Unit [IU]/ml) were enrolled. These patients were randomized into two equal groups to receive one dose of intramuscular Td vaccine supplemented with either levamisole 100 mg or placebo daily, six days before and six days after vaccination. The anti-tetanus IgG levels were measured 1 and 6 months after vaccination.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Levamisole in people with Renal Dialysis, run by Shiraz University of Medical Sciences at 1 site in Iran.

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 2 inclusion and 4 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 26 Jul 2013. 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 Iran. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

tetanus seroconversion rate (time frame: 1 month and 6 month post vaccination). 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 NCT00705692, 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 26 Jul 2013.
