What was measured

AUC(0-last) is the area under the plasma concentration versus time curve from time 0 to the time of the last measurable concentration of 1-OH-Midazolam alone or in combination with erdafitinib.

Analysis population: Pharmacokinetic analysis set included all participants who received at least 1 dose of study drug and had at least 1 sample collected during treatment to determine the drug concentration. Here 'N' (number of participants analyzed) signifies number of participants who were evaluable for this outcome measure.

Groups in this outcome

DDI Study: 1-OH-Midazolam 2.5 mg Alone

Participants received single dose of pretreatment 1-OH-Midazolam 2.5 mg syrup, orally, once daily, starting from Day -2 through Day 13 of Cycle 1 (each cycle length=28 days).

DDI Study: 1-OH-Midazolam 2.5 mg + Erdafitinib 8 mg

Participants received single dose of pretreatment 1-OH-Midazolam 2.5 mg syrup, orally, once daily, starting from Day -2 through Day 13 of Cycle 1 along with erdafitinib 8 mg starting from Day 1 up to Day 15 of Cycle 1 (each cycle length=28 days).
