what the primary-completion date above is the date OFPart A: Area under concentration-time curve from time 0 to infinity (AUCinf) of midazolam
measured Period 1 (Day 1) and Period 3 (Day 7 to Day 8)
Part A: Area under concentrationcurve from time 0 to the last quantifiable concentration (AUClast) of midazolam
measured Period 1 (Day 1) and Period 3 (Day 7 to Day 8)
Part A: Maximum observed plasma (peak) drug concentration (Cmax) of midazolam
measured Period 1 (Day 1) and Period 3 (Day 7 to Day 8)
Part B: Area under concentration-time curve from time 0 to infinity (AUCinf) of camizestrant
measured Period 1 (Day 1 to Day 4), Period 2 (Day 22 to Day 25)
Part B: Area under concentrationcurve from time 0 to the last quantifiable concentration (AUClast) of camizestrant
measured Period 1 (Day 1 to Day 4), Period 2 (Day 22 to Day 25)
