Brief Summary
This first-in-human study has three parts. In Parts A and B, the safety, tolerability, and pharmacokinetics (PK) will be evaluated following administration of single and multiple doses of KRP-A218, including food-effect. In Part C, the drug-drug interaction (DDI) with itraconazole will be evaluated.

Outcome Measures
Primary Outcomes (9)
Part A: Number of Participants With Adverse Events
A treatment-emergent adverse event (TEAE) was defined as an adverse event that started during or after the first dose, or started prior to the first dose and increased in severity after the first dose. Where a subject experienced multiple TEAEs with the same preferred term for the same treatment, this was counted as 1 TEAE for that treatment under the maximum severity recorded.
Screening to follow-up (Approximately 6 weeks)
Part B: Number of Participants With Adverse Events
A treatment-emergent adverse event (TEAE) was defined as an adverse event that started during or after the first dose, or started prior to the first dose and increased in severity after the first dose. Where a subject experienced multiple TEAEs with the same preferred term for the same treatment, this was counted as 1 TEAE for that treatment under the maximum severity recorded.
Screening to follow-up (Approximately 8 weeks)
Part C: Area Under Concentration-time Curve From Time 0 Extrapolated to Infinity (AUC0-infinity)
The area under concentration-time curve from time 0 extrapolated to infinity (AUC0-infinity) following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
Part C: Area Under Curve From Time 0 to the Time of the Last Quantifiable Concentration (AUC0-tlast)
The area under concentration-time curve from time 0 extrapolated to last quantifiable concentration following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
Part C: Maximum Observed Concentration (Cmax)
The maximum observed concentration following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
Part C: Time of the Maximum Observed Concentration (Tmax)
The time of the maximum observed concentration following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
Part C: Apparent Terminal Elimination Half-life (t1/2)
The apparent terminal elimination half-life following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
Part C: Apparent Total Clearance (CL/F)
The apparent total clearance following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
Part C: Apparent Volume of Distribution During the Terminal Phase (Vz/F)
The apparent volume of distribution during the terminal phase following Oral Dose Administration of KRP-A218 Alone and in Combination with Itraconazole
Days 1 to 11
