The FLOTILLA Study: Providing Continued Access to The Study Medicines Encorafenib and Binimetinib for Participants in Prior Clinical Trials

April 6, 2026 updated by: Pfizer

ENCORAFENIB/BINIMETINIB MASTER PROTOCOL: AN OPEN-LABEL CONTINUATION STUDY FOR PARTICIPANTS CONTINUING FROM ENCORAFENIB/BINIMETINIB CLINICAL STUDIES

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. People may not participate in the FLOTILLA study if they have not enrolled in a prior study of encorafenib or binimetinib.

Participants that had enrolled but had stopped receiving the study treatment in a prior study cannot enrolled in this study. Participants in the FLOTILLA study will receive encorafenib and/or binimetinib at the same dose and frequency as in their prior study, for up to about 5 years.

Study Overview

Detailed Description

This is an open-label, continuation study for participants receiving study intervention(s) in an encorafenib/binimetinib Parent Study. The study is being conducted under a Master Protocol for Encorafenib/Binimetinib Continuation Sub-Studies with an individual encorafenib/binimetinib continuation sub-study protocol for each eligible Parent Study. Approximately 75 participants from potentially qualifying Parent Studies will be included in this Encorafenib/Binimetinib Continuation study.

This continuation study includes multiple sub-study protocols to allow participants from each of the following parent studies: C4211001 - NCT01320085; C4211003 - NCT01849874; C4221003 - NCT03864042; C4221005 - NCT01543698; C4221006 - NCT03911869; C4221009 - NCT02928224; C4221010 - NCT01436656; C4221013 - NCT02159066; ANCHOR-CRC - NCT03693170

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Binimetinib only treatment
For those participants receiving binimetinib treatment in parent studies
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.
Experimental: Encorafenib only Treatment
For those participants receiving encorafenib only treatment in parent studies
Encorafenib will be self-administered at the same dose level as that received in the C4221010 Parent Study.
Experimental: Encorafenib & Binimetinib Treatment
For those participants receiving encorafenib & binimetinib treatment in parent studies.
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.
Experimental: Treatment of Encorafenib & Binimetinib & Ribociclib
For those participants receiving treatment of encorafenib & binimetinib & ribociclib in parent studies
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.
Experimental: Treatment of Encorafenib & Binimetinib & Cetuximab
