Inclusion criteria

  • Healthy male and/or female subjects of non-childbearing potential between the ages of 18 and 55 years, inclusive.
  • Body mass index of 17.5 to 30.5 kg/m2, and a total body weight >50 kg (110 lbs).
  • Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
  • Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion criteria

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic diseases.
  • Any condition possibly affecting drug absorption.
  • A positive urine drug screen or alcohol breath test.
  • Pregnant female subjects; breast feeding female subjects, female subjects of childbearing potential, male subjects with partners currently pregnant, male subjects of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for 90 days after the last dose of investigational product.

Treatment and study plan

Palbociclib Alone

Drug

A single 125 mg dose of palbociclib free base capsule given orally alone in the fed state, followed by 120 hours of PK sample collection

Other names: Palbociclib, PD-0332991

Palbociclib plus itraconazole

Drug

Itraconazole 200 mg once daily with food for a total of 11 days; on Day 5, a single oral 125 mg dose of palbociclib will be given with itraconazole after a meal, followed by 168 hours of PK sample collection.

Other names: Palbociclib (PD-0332991); Itraconazole (Sporanox)

Primary outcomes

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]

    Time frame: 0 to 168 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).

  2. Maximum Observed Plasma Concentration (Cmax)

    Time frame: 0 to 168 hours

Secondary outcomes

  1. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Time frame: 0 to 168 hours

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

  2. Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Time frame: 0 to 168 hours

  3. Plasma Decay Half-Life (t1/2)

    Time frame: 0 to 168 hours

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

  4. Apparent Oral Clearance (CL/F)

    Time frame: 0 to 168 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.

  5. Apparent Volume of Distribution (Vz/F)

    Time frame: 0 to 168 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.
