Taste Assessment Study of SHP429 in Healthy Adult Subjects

A taste assessment was completed immediately after investigational product was administered to assess the subject's taste/liking of the formulation. The assessment consisted of a 5-point rating scale. Participants were asked to choose one of the following responses to the statement "The taste was acceptable": strongly agree, agree, neutral, disagree, or strongly disagree. The number of participants who chose either of the top two responses (strongly agree, agree) is reported.

An aftertaste assessment was completed 5 minutes after administration of investigational product to assess whether the participants detected an aftertaste. The participants answered "Yes" or "No" to the following question: "Was there an aftertaste?" The number of participants who answered "Yes" is reported.

An aftertaste assessment was completed 5 minutes after administration of investigational product to assess the subject's rating of aftertaste and means of administration. The assessment consisted of a 5-point rating scale. The participants were asked to choose one of the following responses to the statement "The aftertaste (if present) was acceptable": strongly agree, agree, neutral, disagree, or strongly disagree. The number of participants who chose either of the top two responses (strongly agree, agree) is reported.

The participants were asked to answer "Yes" or "No" to the following question: "Would you be willing to take medicine this way on a regular basis if necessary?" The number of participants who answered "Yes" is reported.

Participants were monitored for treatment-emergent adverse events through the follow-up assessment, which occurred 2 days +/- 1 day post-dose.

Clinical laboratory assessments included hematology, chemistry and urinalysis parameters, all measured 6 hours post-dose. All clinical laboratory assays were performed according to the laboratory's normal procedures. Reference ranges were supplied by the laboratory and were used to assess the clinical laboratory data for clinical significance and out-of-range pathological changes. The investigator assessed out-of-range clinical laboratory values for clinical significance and indicated whether or not the values were clinically significant.

Vital sign assessments included systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate and body temperature measurements, all measured 6 hours post-dose. Study personnel used both absolute values and change from baseline values to determine if the vital sign was potentially clinically important. Criteria for the potential clinical importance of both absolute and change from baseline values were pre-specified. A participant's vital sign had to meet both the absolute and change from baseline criteria to be considered as potentially clinically important.

Subjects underwent a standard 12-lead ECG 6 hours post-dose. The investigator assessed if the ECG tracing was normal or abnormal; if abnormal, the investigator made a determination of whether or not the abnormality was clinically significant.
