Trial summary

This is a clinical trial to compare two formulations of the drug ivermectin: the standard 3mg tablet formulation versus a newly developed infant formula preparation. The goal of the trial is to determine if the new formulation functions in the same way, tastes the same and causes no new side effects. Read more about this study

About this study

This is a clinical trial to compare two formulations of the drug ivermectin: the standard 3mg tablet formulation versus a newly developed infant formula preparation. The goal of the trial is to determine if the new formulation functions in the same way, tastes the same and causes no new side effects. The trial will involve 52 participants who will be healthy adult volunteers. The participants will receive both formulations - the order they receive each formulation will be assigned randomly (similar to the toss of a coin).

Read the detailed description

Randomised open-label cross-over trial of 52 healthy adult volunteers comparing two ivermectin formulations: the standard tablet formulation, and a newly developed infant formula preparation. Participants will be randomised to receive one of these two formulations at the start of the trial and after a 21 day wash out period will be given the alternative formulation. Blood samples will be taken to determine serum drug concentrations. The bioequivalence, tolerability and drug-related adverse effects will be evaluated.

What participants receive

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

  • ivermectin infant formula preparationDrug

    The ivermectin infant formula preparation is produced by micronizing the standard 3mg ivermectin tablet and then blending it with Stage 1 infant formula (Blackmores brand) to produce a homogenous powder. This powder blend of ivermectin and infant formula is then filled into food grade clear capsules.

What is being measured

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

  1. Serum ivermectin Area Under the Curve (AUC) 0-96h bioequivalence across the 2 formulations (standard ivermectin tablet versus new infant formula preparation)

    The serum ivermectin Area Under the Curve (AUC) 0-96h for both the new infant formula preparation and the standard 3 mg tablet will be measured. Bioequivalence is defined as the 90% Confidence Interval (CI) of the geometric mean ratio of AUC 0-96h of the infant formula preparation relative to the standard 3mg tablet falling within 80-125%.

    Measured: 31 days

  2. Serum ivermectin Maximum Concentration (Cmax) bioequivalence across the 2 formulations (standard ivermectin tablet versus new infant formula preparation)

    The serum ivermectin Maximum Concentration (Cmax) for both the new infant formula preparation and the standard 3 mg tablet will be measured. Bioequivalence is defined as the 90% Confidence Interval (CI) of the geometric mean ratio of Cmax of the infant formula preparation relative to the standard 3mg tablet falling within 80-125%.

    Measured: 31 days

Secondary outcomes (2)
  1. Safety as measured by the proportion of participants experiencing one or more drug-related adverse effect(s) with each ivermectin formulation

    Proportion of participants who experience one or more drug-related adverse effects with each ivermectin formulation

    Measured: 51 days

  2. Palatability of the new infant formula preparation as measured by a visual analogue scale (VAS)

    Palatability of the new infant formula preparation will be assessed using a visual analogue scale to assess bitterness and overall likeability. The scale used for this VAS tool will be 0 to 10. For the question on overall likeability, a higher score will correspond with a higher level of likeability. For the question on bitterness, a higher score will indicate a higher level of bitterness.

    Measured: 51 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ivermectin infant formula preparation and Standard ivermectin 3mg tablet in people with Scabies, run by Murdoch Childrens Research Institute at 1 site in Australia.

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 8 inclusion and 6 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: paused, as of the sponsor's last update on 9 Oct 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 Australia. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Results are not available in the source record.

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?

Serum ivermectin Area Under the Curve (AUC) 0-96h bioequivalence across the 2 formulations (standard ivermectin tablet versus new infant formula preparation) (time frame: 31 days). 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 NCT06918665, which also lists 9 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 9 Oct 2026.
