Brief summary
The purpose of this study is to compare the sweetness of 2 new atazanavir powder for oral use (POU) formulations to the current atazanavir POU in healthy participants and to select 1 atazanavir POU that has the sweetness most similar to the current atazanavir POU.
Detailed description
This study is a taste assessment study designed to select a new atazanavir powder for oral use (POU) formulation that is similar in sweetness to the current POU formulation. Participants were to taste and then spit out the POU formulations, without swallowing them. Study Classification: Other. This is a taste study

|---|---|---|
| Median Scores on a Subjective Sweet Intensity Scale for Current and New Powder for Oral Use (POU) Formulations of Atazanavir | Study Day 1 | Tasting atazanavir (15 mg, administered as a 5 mL oral suspension) was defined as taking the sample into the mouth, swishing it across the tongue for approximately 30 seconds without swallowing, and then spitting it out. Immediately after tasting each treatment, participants scored the treatments for sweetness using a subjective sweet intensity scoring system: 0=not sweet, 1=mildly sweet, 2=moderately sweet, 3=very sweet. Participants were permitted to select a whole or half score number (for example, 1.5) between the minimum score of 0 and the maximum score of 3.0. The higher the score, the greater the sweetness. |
