About this study

Official title: Comparison of Ivermectin Alone With Albendazole (ALB) Plus Ivermectin (IVM) in Their Efficacy Against Onchocerciasis in the Volta Region, Ghana.

We will examine whether a combination of Ivermectim (IVM) plus Albendazole (ALB) compared to IVM alone given annually, which is the current standard for mass drug administration (MDA), is more effective in sterilizing adult worms. We will also address whether IVM plus ALB given twice per year is superior to IVM given once per year or twice per year.

Read the detailed description

We hypothesize that more effective combinations of dose schedules of existing antifilarial drugs for MDA against onchocerciasis could shorten the number of years needed to interrupt onchocerciasis transmission and eliminate this infectious disease in areas that previously had high disease rates. Improved treatments should also make it feasible to extend MDA into areas that are currently not being helped. These changes have the potential to completely change the game to make global elimination of onchocerciasis a feasible goal.

Participants will be randomized into 5 treatment arms with 75 subjects in each arm for a total of 375 and followed for 36 months after the initial treatment. The primary endpoint will be the percent fertile adult female worms in nodules removed 36 months after the initiation of treatment.

What is being measured

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

  1. parasitologic efficacy

    To compare the parasitologic efficacy, as measured by percent fertile adult female worms in nodules at 36 months after administration of annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvolus

    Measured: 36 months

Secondary outcomes (6)
  1. additional measures of parasitologic efficacy

    To compare additional measures of parasitologic efficacy of annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvulus as measured by skin microfilaria levels at additional time points.

    Measured: 0, 6, 12, 18, 24 and 36 months

  2. compare the percentage living versus dead female worms

    To compare the percentage living versus dead female worms in nodules at 36 months following initiation of therapy of annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvulus.

    Measured: 36 months

  3. compare the number of nodules with intact microfilaria

    To compare the number of nodules with intact microfilaria (Mf) at 36 months after administration annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvulus.

    Measured: 36 months

  4. assess different treatment regimens on Soil Transmitted Helminth infections

    To assess different treatment regimens on Soil Transmitted Helminth (STH) infections based on presence and intensity of ova in stools.

    Measured: 0, 6, 12, 18, 24 and 36 months

  5. determine if IVM plus ALB enhances immunological reactions

    To determine if IVM plus ALB enhances immunological reactions to adult worms antigens, or release of circulating parasite antigens as potential biomarkers of drug efficacy.

    Measured: 0, 6, 12, 18, 24 and 36 months

  6. determine if the host immune response facilitates killing or sterilizing adult worms and microfilariae

    To determine if the host immune response facilitates killing or sterilizing adult worms and microfilariae. This can be accomplished by examining immune biomarkers prior to and following treatment using stored whole blood, and serum/plasma samples.

    Measured: 0, 6, 12, 18, 24 and 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing IVM plus ALB and IVM in people with Onchocerciasis, run by University Hospitals Cleveland Medical Center at 1 site in Ghana.

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 26 Apr 2019. 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 Ghana. 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 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?

parasitologic efficacy (time frame: 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Apr 2019.
