About this study

Official title: 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).

Being tested
Rifampin, Vemurafenib
Medical subject headings
Melanoma, Neoplasms

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Rifampin at a dose of 600 mg as capsules orally once daily will be administered from Days 8 through 23 (Periods B and C).

  • VemurafenibDrug

    Also called RO5185426, Zelboraf

    Participants, after an overnight fast of at least 10 hours, will receive vemurafenib at a dose of 960 mg as film-coated tablets orally on Day 1 (Period A) and on Day 17 (Period C).

Study groups in NCT01765543
Study groupRoleWhat they receive
Vemurafenib + RifampinExperimentalThere will be 3 intervention periods in the study: Period A (Days 1 to 7), Period B (Days 8 to 16), and Period C (Days 17 to 24). Participants, after an overnight fast of at least 10 hours, will receive vemurafenib at a dose of 960 milligrams (mg) as film-coated tablets orally alone on Day 1 (Period A); with rifampin (at a dose of 600 mg as capsules orally) on Day 17 (Period C); and rifampin alone at a dose of 600 mg as capsules orally once daily will be administered from Days 8 through 16 (Period B) and from Days 18 through 23 (Period C).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Area Under the Plasma Concentration Time-curve From Zero to the Last Measurable Concentration Time Point (AUClast) of Vemurafenib

    AUClast is the area under the vemurafenib plasma concentration versus time curve from time zero to the time of last measured concentration of vemurafenib (Tlast). Area under the curve (AUC) is a measure of the plasma concentration of a drug over time. AUClast is presented in micrograms times (*) hour per milliliter (mcg*h/mL).

    Measured: 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)

  2. Area Under the Plasma Concentration Time-curve From Zero to Extrapolated Infinite Time (AUC[0-inf]) of Vemurafenib

    AUC(0-inf) is the AUC from time zero (pre-dose) to extrapolated infinite time (0-inf). AUC is a measure of the plasma concentration of a drug over time. AUC(0-inf) is presented in mcg*h/mL.

    Measured: 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)

  3. Maximum Observed Plasma Concentration (Cmax) of Vemurafenib

    Cmax is the maximum observed plasma vemurafenib concentration, presented in microgram per milliliter (mcg/mL).

    Measured: 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)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Rifampin and Vemurafenib in people with Malignant Melanoma, Neoplasms, run by Hoffmann-La Roche at 15 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Egypt, Brazil, Croatia, South Africa. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Dec 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area Under the Plasma Concentration Time-curve From Zero to the Last Measurable Concentration Time Point (AUClast) of Vemurafenib (time frame: 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 study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2016.
