A Study of the Effect of Vemurafenib on the Pharmacokinetics of Phenprocoumon in Patients With BRAFV600 Mutation-Positive Metastatic Malignancy

November 1, 2016 updated by: Hoffmann-La Roche

A PHASE I, OPEN-LABEL, MULTICENTER, RANDOMINZED, PARALELL STUDY TO INVESTIGATE THE EFFECT OF VEMURAFENIB ON THE PHARMACOKINETICS OF A SINGLE ORAL DOSE OF PHENPROCOUMON IN PATIENTS WITH BRAFV600 MUTATION-POSITIVE METASTATIC MALIGNANCY

This open-label, multicenter, parallel study will evaluate the effect of multiple doses of vemurafenib on the pharmacokinetics of a single dose of phenprocoumon in patients with BRAFV600 mutation-positive metastatic malignancies. Patients will be randomized to receive either treatment A: a single oral dose of phenprocoumon 6 mg on Day 1 (Eligible patients will have the option to continue treatment with vemurafenib as part of an extension study (NCT01739764).), or treatment B: vemurafenib 960 mg orally twice daily on Days 1-29 plus a single oral dose of phenprocoumon 6 mg on Day 22 (with the option to receive vemurafenib in the extension study after completion of pharmacokinetic assessments).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
