Effects of Food on Oxycodone Pharmacokinetics in Healthy Volunteers

Phase 1
Completed
Conditions
Healthy

Registration Number
NCT02117583
Lead Sponsor
Pain Therapeutics
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]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).

Maximum Observed Plasma Concentration (Cmax)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48
Secondary Outcome Measures
NameTimeMethod
Plasma Decay Half-Life (t1/2)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.

Time to Reach Maximum Observed Plasma Concentration (Tmax)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)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)

Concentration at time 24 hours (C24)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48
