What this trial studies
The FLOTILLA study aims to provide ongoing access to the medications encorafenib and binimetinib for participants who have previously benefited from these treatments in earlier clinical trials. This open-label continuation study allows eligible participants to receive the same dosage and frequency of the medications for up to five years, ensuring safety follow-up and monitoring. Participants must have been part of prior studies involving these drugs and must still be experiencing clinical benefits as determined by their study doctor.
Why it matters
