View original scientific description
The purpose of this clinical trial (called the FLOTILLA study) is to give continued access to the study medicines, as well as safety follow-up, for participants in prior clinical trials of encorafenib and/or binimetinib. All participants who took part in earlier encorafenib and/or binimetinib studies may participate the FLOTILLA study if they are still benefiting from the use of the study medicines. This will be determined by the study doctor.
Interventions
DRUG
Binimetinib only treatment
Binimetinib will be administered at the same dose level (15 mg to 45 mg) as that received in the Parent Studies C4211001 and C4211003 with water irrespective of food, continuously, starting on Day 1.
DRUG
Encorafenib only Treatment
Encorafenib will be self-administered at the same dose level as that received in the C4221010 Parent Study.
DRUG
Encorafenib & Binimetinib Treatment
Encorafenib will be administered on a 300 mg QD schedule and binimetinib will be administered on a 45 mg BID schedule, both orally as a flat fixed dose. Cetuximab will be administered at either 400 mg/m2 or 500 mg/m2 IV every 2 weeks on Days 1 and 15 of every cycle.
DRUG
Treatment of Encorafenib & Binimetinib & Ribociclib
Encorafenib capsule and ribociclib capsules or tablets will be co-administered orally QD with binimetinib tablets BID. The study drugs will be administered as a flat-fixed dose, and not by body weight or body surface area.
DRUG
Treatment of Encorafenib & Binimetinib & Cetuximab
Encorafenib will be administered on a 300 mg QD schedule and binimetinib will be administered on a 45 mg BID schedule, both orally as a flat fixed dose. Cetuximab will be administered at either 400 mg/m2 or 500 mg/m2 IV every 2 weeks on Days 1 and 15 of every cycle.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
