Descriptive Information
Brief Title  ICMJE A Pilot Study To Investigate The Effect Of Concurrent Antacid Administration On The Bioavailability Of Six Experimental Formulations Of Palbociclib
Official Title  ICMJE A Phase 1, Open?Label Fixed?Sequence 2?Period Crossover Study Of Palbociclib (pd?0332991) In Healthy Volunteers To Estimate The Effect Of Antacid Treatment On The Bioavailability Of A 125 Mg Single Dose Of Six Experimental Formulations Of Palbociclib Relative To Palbociclib Administration Alone Under Fasted Conditions
Brief Summary This study will investigate whether concurrent administration of rabeprazole, an antacid known as a proton pump inhibitor, alters the absorption of the drug palbociclib when given as one of six experimental formulations.
Detailed Description This will be a 6 cohort study investigating one experimental formulation of palbociclib in each of the six cohorts of 10 healthy subjects. Each cohort will receive two treatments in a fixed-sequence. In Period 1, all subjects will receive a single 125mg dose of palbociclib alone and undergo serial pharmacokinetic blood sampling for up to 120 hours post-dose. In Period 2, all subjects will receive daily 40mg doses of Rabeprazole for 7 consecutive days, and approximately 4 hours after the Day 7 rabeprazole dose each subject will receive a single 125mg dose of palbociclib. Subjects will undergo serial pharmacokinetic blood sampling up to 120 hours post-dose.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: Non-Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Condition  ICMJE Healthy
Intervention  ICMJE
  • Drug: Palbociclib Alone
    In Period 1 of each Cohort, a single 125 mg dose of palbociclib will be administered alone in a fasted state, and subjects will undergo serial pharmacokinetic blood sampling for up to 120 hours post-dose.
    Other Name: Palbociclib, PD-0332991
  • Drug: Palbociclib + Rabeprazole
    In Period 2 of each Cohort, subjects will receive daily 40 mg oral doses of the proton pump inhibitor rabeprazole on 7 consecutive days. Approximately 4 hours after the last rabeprazole dose a single 125 mg dose of palbociclib will be administered alone in a fasted state, and subjects will undergo serial pharmacokinetic blood sampling for up to 120 hours post-dose.
