Study Endpoints

Primary Endpoints

Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-∞)]
0 (Pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hours (hrs) post crizotinib dose in period 1 and day 0, 0 (pre-dose), 1, 2, 4, 6, 8, 10, 12, 24, 48, 72, 96, 144, 192 and 312 hrs post crizotinib dose in period 2

AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞).

Maximum Observed Plasma Concentration (Cmax)
0 (Pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and day 0, 0 (pre-dose), 1, 2, 4, 6, 8, 10, 12, 24, 48, 72, 96, 144, 192 and 312 hrs post crizotinib dose in period 2
To evaluate the effects of multiple oral doses of ketoconazole on the pharmacokinetic (PK) profile of a single oral dose of HCV-796 in healthy subjects.

Time to Reach Maximum Observed Plasma Concentration (Tmax)
0 (Pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and day 0, 0 (pre-dose), 1, 2, 4, 6, 8, 10, 12, 24, 48, 72, 96, 144, 192 and 312 hrs post crizotinib dose in period 2

Frequently asked questions about ketoconazole

What is ketoconazole used for?

Ketoconazole is an investigational small molecule being studied in healthy volunteers for drug interaction trials. It is used as a probe to assess the impact of multiple doses on the pharmacokinetics of other drugs, such as HCV-796 and crizotinib. It is not approved for any indication.

Who makes ketoconazole?

Ketoconazole is being developed by Pfizer, Inc. (NYSE: PFE). The company is conducting clinical trials to evaluate its effects on the pharmacokinetics of other drugs in healthy volunteers.

What phase is ketoconazole in?

Ketoconazole is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Two Phase 1 trials have been completed, both involving healthy volunteers.

What clinical trials is ketoconazole in?

Ketoconazole has been studied in two completed Phase 1 trials: NCT00384917, which examined its impact on the pharmacokinetics of HCV-796, and NCT01149785, which estimated its effect on crizotinib pharmacokinetics. Both trials enrolled healthy volunteers.

Is ketoconazole the same as crizotinib?

No, ketoconazole is not the same as crizotinib. Ketoconazole is being studied as a potential inhibitor of drug-metabolizing enzymes, while crizotinib is a separate drug whose pharmacokinetics are being evaluated when co-administered with ketoconazole in a clinical trial.
