Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]
Time Frame: 0-120 hours
AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).
0-120 hours
Maximum Observed Plasma Concentration (Cmax)
Time Frame: 0-120 hours
0-120 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Plasma Palbociclib Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Time Frame: 0 to 120 hours
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
0 to 120 hours
Plasma Palbociclib Time to Reach Maximum Observed Plasma Concentration (Tmax)
Time Frame: 0 to 120 hours
0 to 120 hours
Plasma Palbociclib Decay Half-Life (t1/2)
Time Frame: 0 to 120 hours
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
0 to 120 hours
Apparent Oral Clearance (CL/F) of Palbociclib
Time Frame: 0 to 120 hours
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
0 to 120 hours
Apparent Volume of Distribution (Vz/F) of Palbociclib
Time Frame: 0 to 120 hours
Volume of distribution is 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. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
0 to 120 hours
Trough Plasma Concentrations of Modafinil, Modafinil sulfone, pioglitazone, hydroxy derivative of pioglitazone, and keto derivative of pioglitazone
Time Frame: 0 to 120 hours
0 to 120 hours
Time of last quantifiable concentration for palbociclib
Time Frame: 0 to 120 hours
0 to 120 hours
