A Pharmacokinetics Study to Investigate the Effect of Ketoconazole on Vemurafenib in Patients With BRAFV600 Mutation-Positive Metastatic Melanoma

NCT ID: NCT01765556

Last Updated: 2016-11-02

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE1
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-10-31
• Study Completion Date: 2013-10-31

Brief Summary

This open-label, multi-center, three-period, one sequence study will investigate the effect of ketoconazole on the pharmacokinetics of vemurafenib in patients 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. Patients will receive a single dose of vemurafenib in Periods A and C and multiple doses of ketoconazole in Periods B and C. Eligible patients will have the option to continue treatment with vemurafenib as part of an extension study (NCT01739764). The anticipated time on study treatment is approximately 19 days.
