Brief Summary:
This is a single-centre, open-label Phase II study of the investigational drugs binimetinib and encorafenib that will be taken my mouth (orally) daily in adult patient with advanced and/or metastatic solid tumors for which no other standard therapy is available. The main purpose is to evaluate the objective response rate (ORR) of the study drugs in the growth of the cancer in patients with class 2 and 3 BRAF mutations.

Condition or disease Intervention/treatment Phase
Solid Tumor Drug: Binimetinib Drug: Encorafenib Phase 2

Detailed Description:

BRAF is a gene in humans that is commonly altered in cancer, resulting in a change to the proteins created from this mutation. These altered proteins interact with a process in the body known as the MAPK (mitogen-activated protein kinase) pathway and promote the growth of cancer. Three classes of BRAF mutations have been identified to understand why some patients respond to treatment and others do not. Class 2 and 3 BRAF mutations have worse overall survival. This study will look at participants in these classes (non-V600E BRAF mutations).

Binimetinib is an oral drug (tablet) that stops the function of MEK (mitogen-activated protein kinase kinase). MEK is a part of the MAPK pathway, so blocking this step helps in stopping the pathway from confinuing to grow the cancer.

Encorafenib is an oral drug (capsule) that stops the function of BRAF V600-mutant kinase, the protein that is produced from a type of BRAF gene mutation. This protein promotes the MAPK pathway so blocking this protein stops the MAPK pathway from growing the cancer.

Patients will visit the clinic up to 2 times every 4 weeks (1 cycle) for tests and procedures while taking the study drugs daily. Procedures will involve review of medication and history, imaging scans, blood sample collection for safety and research purposes, urine collection, ECGs, eye exam, MUGA scans and mandatory and optional tumor biopsies.

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: Yes
Plan Description:

Biomarker test results and limited clinical information that does not identify patients may be sent to centralized scientific databases or shared with collaborating researchers outside of UHN. Data from this study can be shared through two types of databases:

Open-Access: publicly accessible and will contain limited clinical information and analyses of patient samples. It will not contain data that can identify an individual.

Controlled-Access: will contain more detailed clinical information and sample analyses. It will be stripped of all personal identifiers. Researchers who use data from this database will sign agreements that define how data may be used. They will not be permitted to disclose or transfer data to others. They must use the data only for the approved purposes and must agree not to attempt to re-identify patients from their data.
