What was measured

Vz/F was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug, and calculated as dose/(AUCinf\*kel), where AUCinf was the area under the plasma concentration-time profile from time 0 extrapolated to infinite time, kel was the rate constant for terminal phase. Only participants in 25 mg and 150 mg QD groups were given midazolam. Day -7 data reflect the PK assessment before administration of PF-06463922, and Cycle 1 Day 15 data reflect the PK assessment after multiple doses of PF-06463922 were administered.

Analysis population: PK parameter analysis set for midazolam included all participants who received at least 1 dose of midazolam and for which at least 1 midazolam PK parameter of interest was available. Here, 'Number Analyzed' signifies participants evaluable for specified rows.

Groups in this outcome

25 mg QD (Phase 1)

PF-06463922 25 mg was orally given QD in 21-day cycles from Cycle 1 Day 1 until progression of disease (unless clinical benefit was still achievable), unacceptable toxicity, death or consent withdrawal. Midazolam 2 mg was orally given QD on Day -7 and Cycle 1 Day 15.

150 mg QD (Phase 1)

PF-06463922 150 mg was orally given QD in 21-day cycles from Cycle 1 Day 1 until progression of disease (unless clinical benefit was still achievable), unacceptable toxicity, death or consent withdrawal. Midazolam 2 mg was orally given QD on Day -7 and Cycle 1 Day 15.
