Trial Outcomes & Findings for VEG113971: An Open-Label Study of the Effects of Ketoconazole or Esomeprazole on Pazopanib PK (NCT NCT01205230)

NCT ID: NCT01205230

Last Updated: 2012-05-22

Results Overview

Blood samples for pharmacokinetic (PK) analysis of pazopanib were obtained at pre-dose (within 60 minutes prior to pazopanib administration) and at 1, 2, 3, 4, 6, 8, and 24 hours after pazopanib administration. From the plasma concentration-time curve, the PK parameter AUC(0-24) was determined by standard non-compartmental analysis using WinNonlin. Plasma AUC(0-24) is a measure of the amount of drug a participant has been exposed to in 24 hours.

Blood samples for PK analysis of pazopanib were obtained at pre-dose (within 60 minutes prior to pazopanib administration) and at 1, 2, 3, 4, 6, 8, and 24 hours after pazopanib administration. From the plasma concentration-time curve, the PK parameter Cmax was determined by standard non-compartmental analysis using WinNonlin. The concentration-time curve is the result of time points of blood sampling and its measured concentration of pazopanib in the plasma.

From the plasma concentration-time curve, the PK parameter tmax was determined by standard non-compartmental analysis using WinNonlin. Nominal data collection time points (TPs) were defined in the protocol; however, the actual data collection TP often differed slightly from the nominal TP for various reasons. This leads to medians and ranges that don't coincide with planned nominal data collection TPs.

Blood samples for the determination of plasma ketoconazole concentrations were collected before (pre-dose \[within 60 minutes prior to pazopanib administration\]) and after the final pazopanib and ketoconazole dose (fifth dose) during Period 2 at the indicated time points, relative to pazopanib administration (at 1 and 2 hours after pazopanib administration). Blood samples were obtained via peripheral intravenous cannula or central line. Concentrations of ketoconazole were determined in plasma samples using the currently approved analytical methodology.

AEs were graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE), Version 4.0. Grades range from 0 (no toxicity) to 4 (life-threatening or disabling). A Grade 3 AE is severe; defined as considerable interference with the participant's daily activities, medical intervention/therapy required, and hospitalization possible. A Grade 4 AE is life-threatening; defined as extreme limitation in activity, significant medical intervention/therapy required, and hospitalization probable.

SECONDARY outcome

Timeframe: From Baseline (Day 1) to a maximum of 4 weeks after the last dose of study drug was administered (on Study Day 12)

Population: All Treated Population. Per protocol, a DLT could not occur during single-agent pazopanib administration in Period 1; thus, data were only collected and analyzed for those participants receiving pazopanib co-administered with either ketoconazole or esomeprazole in Period 2.

The following were considered DLTs only while participants were receiving pazopanib co-administered with either ketoconazole or esomeprazole: Grade 4 hematologic toxicities, excluding lymphopenia; and Grade 3/4 non-hematologic toxicities, excluding alopecia and nausea/vomiting/diarrhea for which adequate supportive therapy had not been instituted. Toxicities observed once co-administration of pazopanib with ketoconazole or esomeprazole was complete (after Day 5 of Period 2) could also be considered DLTs if judged to be relevant by the investigator and the GlaxoSmithKline Medical Monitor.
