A Study of RO5212054 (PLX3603) in Participants With BRAF V600-Mutated Advanced Solid Tumors

July 27, 2017 updated by: Hoffmann-La Roche

An Open-Label, Multiple Ascending Dose (MAD) Study of the Selective BRAF Inhibitor RO5212054 (PLX3603) to Evaluate Safety, Tolerability and Pharmacokinetics in Patients With BRAF V600-Mutated Advanced Solid Tumours

This open-label, multi-center study will evaluate the safety, tolerability, and pharmacokinetics of RO5212054 [PLX3603] in participants with BRAF V600-mutated advanced solid tumors. Cohorts of participants will receive escalating oral doses of RO5212054. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

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

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: RO5212054: Continuous Dosing Cohort
Participants will receive RO5212054 in escalating dose levels.
Drug: RO5212054
Participants will receive RO5212054 at a starting dose of 200 milligrams (mg) orally once daily in each 21 day cycle. Dose levels for escalation will be decided based on the safety assessment of previous cohort. Dose escalations in increments of 50-100 percent are planned.
Other Names:
  • PLX3603
Experimental: RO5212054: New Formulation (F05) Bridging Cohort
Participants will receive RO5212054 as a single dose of new formulation (F05-150 mg film-coated tablet with different ratios of ingredients than F03 to increase bioavailability) and a single dose of current clinical Formulation (F03-150 mg film-coated tablet) in a cross-over manner. Participants will be alternately assigned to receive either F05 or F03 as their first dose, followed by the opposite Formulation as their second dose. Dose of RO5212054 will be decided based on the results of continuous dosing cohort.
Drug: RO5212054
Participants will receive RO5212054 at a starting dose of 200 milligrams (mg) orally once daily in each 21 day cycle. Dose levels for escalation will be decided based on the safety assessment of previous cohort. Dose escalations in increments of 50-100 percent are planned.
