A Pharmacokinetics (PK) Study to Investigate the Effect of Rifampin on PK of Vemurafenib (Zelboraf)

21 de outubro de 2016 atualizado por: Hoffmann-La Roche

A Phase I, Open-Label, Multicenter, Three-Period, One-Sequence Study to Investigate the Effect of Rifampin on the Pharmacokinetics of a Single Oral Dose of 960 mg of Vemurafenib

This open-label, multi-center, three-period, one-sequence study will investigate the effect of rifampin on the PK of vemurafenib in participants with unresectable BRAFV600-mutation positive metastatic melanoma or other malignant tumor type that harbors a V600-activating mutation of BRAF without acceptable standard treatment options. Eligible participants will have the option to continue treatment with vemurafenib as part of an extension study GO28399 (NCT01739764).

Clearance of a drug is a measure of the rate at which a drug is removed (metabolized or eliminated by normal biological processes) from the blood. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed.
Predose (0 hour), 1, 2, 4, 6, 8, 12, 24, 30-32, 48, 72, 96, 120, 168 hours post vemurafenib-dose on Day 1 (Period A) and Day 17 (Period C)

Prazo: Predose (0 hour), 1, 2, 4, 6, 8, 12, 24, 30-32, 48, 72, 96, 120, 168 hours post vemurafenib-dose on Day 1 (Period A) and Day 17 (Period C)

The AUCpeo, that is, percent area obtained after extrapolation from Tlast to infinity is calculated by using the formula AUCpeo = 100*(AUC[0-inf] minus AUC[0-last])/AUC(0-inf). This parameter provides information about what percentage of the theoretical curve AUC(0-inf) is possible to determine experimentally (AUC0-last).
Predose (0 hour), 1, 2, 4, 6, 8, 12, 24, 30-32, 48, 72, 96, 120, 168 hours post vemurafenib-dose on Day 1 (Period A) and Day 17 (Period C)
