-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. 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).

+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.

  • ivermectin infant formula preparation (Drug): 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.
  • Standard ivermectin 3mg tablet (Drug): standard 3mg ivermectin tablet

+Outcome measures

Primary outcomes

  • Serum ivermectin Area Under the Curve (AUC) 0-96h bioequivalence across the 2 formulations (standard ivermectin tablet versus new infant formula preparation) [31 days]: 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%.
  • Serum ivermectin Maximum Concentration (Cmax) bioequivalence across the 2 formulations (standard ivermectin tablet versus new infant formula preparation) [31 days]: 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%.

Secondary outcomes

  • Safety as measured by the proportion of participants experiencing one or more drug-related adverse effect(s) with each ivermectin formulation [51 days]: Proportion of participants who experience one or more drug-related adverse effects with each ivermectin formulation
  • Palatability of the new infant formula preparation as measured by a visual analogue scale (VAS) [51 days]: 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.
