A Pharmacokinetics (PK) Study to Investigate the Effect of Rifampin on PK of Vemurafenib (Zelboraf)
21. Oktober 2016 aktualisiert von: 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).

|
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).
