February 11, 2020 updated by: Genentech, Inc.

A Two-part, Phase I, Open-label, Multicenter, Two-period, One-sequence Study to Investigate the Effect of Itraconazole and Rifampin on the PK of Vemurafenib at Steady State

This is a two-part, Phase 1, open-label, multicenter, two-period, one-sequence study to investigate the effect of itraconazole and rifampin on the PK of vemurafenib following multiple 960 milligrams (mg) twice daily (BID) dosing in adult participants with unresectable Stage IIIC or Stage IV metastatic melanoma positive for the BRAF V600 mutation, or other malignant tumor types that harbor a V600-activating mutation of BRAF where the participant has no acceptable standard treatment options.

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.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Eastern Cooperative Oncology Group Performance Status 0 to 2
  • Life expectancy >=12 weeks
  • Adequate hematologic and end organ function obtained within 2 weeks prior to first dose of study drug
  • Female participants of childbearing potential and male participants with partners of childbearing potential must agree to always use two effective methods of contraception including at least one method with a failure rate of <1% per year during the course of the study and for at least 6 months after completion of study treatment
  • Negative serum pregnancy test within 7 days prior to commencement of dosing in women of childbearing potential
  • Absence of any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule

Exclusion Criteria:

  • Prior treatment with vemurafenib or other BRAF inhibitor within 42 days of Study Day 1 of Period A
  • Allergy or hypersensitivity to components of the vemurafenib formulation

  • Major surgical procedure or significant traumatic injury within 14 days prior to first dose of study drug treatment on Study Day 1 of Period A, or anticipation of the need for major surgery during study treatment
  • Prior anti-cancer therapy (e.g., biologic or other targeted therapy, chemotherapy) within 28 days (6 weeks for nitrosoureas or mitomycin C, and 14 days for hormonal therapy or kinase inhibitors) before the first dose of study treatment on Study Day 1 of Period A.

What is the study measuring?

Primary Outcome Measures

Time Frame: Period A and B: Pre-morning dose on Day 18, 19, and 20 and 1, 2, 3, 4, 6, 8, and 12 hours post-morning dose on Day 20
Period A and B: Pre-morning dose on Day 18, 19, and 20 and 1, 2, 3, 4, 6, 8, and 12 hours post-morning dose on Day 20
Maximum observed concentration (Cmax)
Time Frame: Period A and B: Pre-morning dose on Day 18, 19, and 20 and 1, 2, 3, 4, 6, 8, and 12 hours post-morning dose on Day 20
Period A and B: Pre-morning dose on Day 18, 19, and 20 and 1, 2, 3, 4, 6, 8, and 12 hours post-morning dose on Day 20
Time to maximum concentration (Tmax)
Time Frame: Period A and B: Pre-morning dose on Day 18, 19, and 20 and 1, 2, 3, 4, 6, 8, and 12 hours post-morning dose on Day 20
Period A and B: Pre-morning dose on Day 18, 19, and 20 and 1, 2, 3, 4, 6, 8, and 12 hours post-morning dose on Day 20

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Incidence of adverse events
Time Frame: 28 days after last dose of study treatment (last dose = Day 40)
28 days after last dose of study treatment (last dose = Day 40)
