What was measured
On day 1 of course 1, series blood samples for palbociclib pharmacokinetic studies were collected at pre-dose, 0.5, 1, 2, 4, 8 (±1), 10 (±0.5) optional, 24 (±4), 48 (±4) hours after the oral dose of palbociclib. Half-life (t1/2) was estimated using a non-compartmental method.
Analysis population: Patients with blood samples collected for pharmacokinetic studies on days 1-3 of course 1 were included.
Groups in this outcome
Stratum I, Dose Level 1 (50 mg/m2)
Less-heavily pre-treated patients received oral palbociclib daily at 50 mg/m2/day for 21 days followed by a week rest (one course = 28 days) for up to 26 courses in the absence of disease progression or unacceptable toxicity.
Stratum I, Dose Level 2 (75 mg/m2)
Less-heavily pre-treated patients received oral palbociclib daily at 75 mg/m2/day for 21 days followed by a week rest (one course = 28 days) for up to 26 courses in the absence of disease progression or unacceptable toxicity.
Stratum I, Dose Level 3 (95 mg/m2)
Less-heavily pre-treated patients received oral palbociclib daily at 95 mg/m2/day for 21 days followed by a week rest (one course = 28 days) for up to 26 courses in the absence of disease progression or unacceptable toxicity.
Stratum II, Dose Level 1 (50 mg/m2)
