Effects of Food on Oxycodone Pharmacokinetics in Healthy Volunteers

To estimate the effect of food on the pharmacokinetics and relative bioavailability of oxycodone following oral administration of single 40 mg doses of PF 00345439 Formulation K taken whole or after chewing in healthy volunteers. We have described below the two cohorts each with two arms in this crossover study by listing them as four Arms/Groups in order to capture the differences between the cohorts prior to the crossover and after the crossover. 14 participants are planned for the first cohort and 18 participants are planned for the second cohort.

Treatment and study plan

Oxycodone

Drug

One capsule of 40 mg PF-00345439 Formulation K, taken whole, single dose, under fasting conditions

Primary outcomes

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

    Time frame: 0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

    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: 0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

Secondary outcomes

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

    Time frame: 0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

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

  2. Concentration at time 24 hours (C24)

    Time frame: 0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

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

    Time frame: 0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

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

    Time frame: 0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

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