Trial Design

2 Treatment Groups

Binimetinib + Encorafenib

This trial requires 26 total participants across 2 different treatment groups

This trial involves 2 different treatments. Binimetinib is the primary treatment being studied. Participants will all receive the same treatment. There is no placebo group. The treatments being tested are in Phase 2 and have already been tested with other people.

Binimetinib + EncorafenibBinimetinib and encorafenib are administered orally on a twice daily or once daily schedule, respectively in 28-day cycles. Treatment will continue until it is discontinued due to unacceptable toxicity, clinical or radiological disease progression as per RECIST 1.1, investigator decision, and/or withdrawal of consent.

Eligibility Criteria

This trial is for patients born any sex aged 18 and older. There are 10 eligibility criteria to participate in this trial as listed below.

Mark “yes” if the following statements are true for you:
Patient must be diagnosed with a histologically or cytologically-documented, locally-advanced, or metastatic solid malignancy that is incurable and has either (a) failed prior standard therapy, (b) for which no standard therapy exists, or (c) standard therapy is not considered appropriate by the patient and treating physician.
Measurable disease by RECIST v1.1 criteria.
All patients enrolled must be willing and able to provide at least 1 archival and/or fresh tumor biopsy at baseline for histopathological and molecular evaluation during the screening period with binimetinib and encorafenib. Additional matched pre-treatment and on-treatment fresh tumor biopsies are mandatory for 10 patients enrolled in stage 2. Any patient with insufficient or inadequate archival tissue samples will be required to provide a fresh tumor biopsy. For all other patients, a fresh baseline biopsy is optional, but highly recommended. If a patient only has a single measurable lesion by RECIST v1.1, this lesion can be used for baseline biopsy if it is 2cm or greater.
Informed consent
Signed written and voluntary informed consent.
Patient must be willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures.
Age > 18 years, male or female.
Disease characteristics
Malignancy must express one of the following BRAF alterations: BRAF mutation affecting codon: 241, 257, 367, 462, 463, 464, 466, 467, 469, 485, 581, 586, 594, 595, 596, 597 598, 599, 601; V600 BRAF mutations: V600K (for any malignancy except melanoma), V600D, V600M, V600R; BRAF deletions ie. V600_K601delinsE or 1799_1801 del TGA; BRAF insertions ie. T599dup; BRAF fusions ie. KIAA1549:BRAF
Patient must be able to swallow pills

What are common treatments for cancer?

Add answer

The majority of cancer patients are diagnosed with curable cancer with surgery, radiation, or other treatment options, such as chemotherapy, hormonal or biologic agents, radiation therapy, and immunotherapy. The type and location of the cancer also impacts the treatment that is most recommended for the patient.

Unverified Answer

How many people get cancer a year in the United States?

Add answer

Approximately 4 million people a year are diagnosed with cancer in the USA, making it the second most common cause of mortality after heart disease, after non-fatal injuries.

Unverified Answer

What causes cancer?

Add answer

Cancer is the result of a combination of genetic risk factors and environmental exposures. Smoking, a major environmental risk factor, may be associated with the increased risk of developing [breast cancer](, colorectal cancer and cancer of the thyroid. Other environmental risks include sun exposure and UV radiation, diet, alcohol, and many recreational drugs. The exact mechanism by which lifestyle factors cause cancer is not entirely clear. Exposure to environmental agents may enhance or deregulate biological processes that otherwise occur randomly.

Unverified Answer

What is cancer?

Add answer

The term cancer means growth out of control. When we look at the human body and think about cancer, we often focus on its most obvious physical symptoms—the white blood cell counts, a person's weight, tumor size, bone density, and tumor location. These symptoms do not come from only the part of the body in which the cancer forms and begins to grow. Another term for a cancer is 'a disease or disorder which is not caused by infection, but whose most prominent sign and symptom are those involving the growth of tumours'.

Unverified Answer

What are the signs of cancer?

Add answer

The symptoms of cancer may indicate the cancer and depend on the type of cancer. A high fever raises the possibility of leukemia and some solid cancers (such as kidney cancer) may cause bone pain. It is prudent to consider all of the above symptoms and make the right diagnosis.

Unverified Answer

Can cancer be cured?

Add answer

Treatment-related issues of prognosis and quality of life can significantly influence the patient's perception of cure. However, treatment-induced cure might still be possible, but much more likely to occur if tumour response to initial treatment were optimal.

Unverified Answer

Is binimetinib typically used in combination with any other treatments?

Add answer

Binimetinib is most commonly combined with other treatments, especially with temsirolimus. Some of its side effects may be alleviated by using a more selective CYP1A1 inhibitor such as astemizole or the newer and more specific CYP1A1 inhibitor afatinib.

Unverified Answer

What is the latest research for cancer?

Add answer

The information that is provided in cancer and other diseases has drastically improved in recent years, it has become more accessible and there is so much more information available to the general public. If people were to read more about the latest research there is a possibility of them becoming aware of more risk factors and how to prevent themselves from getting cancer. Many people still do not have the knowledge to know how to prevent themselves.

Unverified Answer

What are the common side effects of binimetinib?

Add answer

Most binimetinib side effects were mild to moderate and mild/moderately reversible according to the FDA's recommendation. Many patients had no side effects on the first or second dose of binimetinib at the 240 mg dose. The most common side effects were fatigue, insomnia (<24%), headache, rash, nausea, diarrhea, abdominal pain, and constipation when binimetinib was discontinued. Some patients and people taking other medicines concurrently may not show the listed side effects; thus side effect results may be different in different people. Some of the side effects listed above may also be related to some of the diseases or medicines (mainly chemotherapy) that some people take concurrently.

Unverified Answer

What is the primary cause of cancer?

Add answer

Some of the factors that are thought to be significant or important in the development of cancer in most cases are genetic factors and environmental factors. Many of the human cancers are caused by mutational events that cause changes in the genes involved in cell growth and survival and the DNA repair mechanisms that protect cells. However, other factors, such as lifestyle, environment, occupation, diet and other environmental conditions may also enhance the risk of cancer in the general population. Current evidence has led to several theories on the causes of cancer, which have become major trends for understanding cancer causality and causation.

Unverified Answer

Is binimetinib safe for people?

Add answer

Binimetinib induced very few adverse events in the Phase 3 trial. No clinical meaningful differences between binmetinib and placebo were observed, in both terms of patient quality of life and safety in adults. In this trial, the frequency of fatigue was not higher in the binmetinib cohorts relative to placebo.

Unverified Answer

How does binimetinib work?

Add answer

Binimetinib inhibits several cell lines of the BT family of cancer cells in vitro and is well tolerated and presents no significant risk of toxicity in vitro or in vivo in healthy monkeys or primates. binimetinib exhibits both in vitro and in vivo potency as a bcr-abl inhibitor. This observation is consistent with the in vivo efficacy and lack of toxicity noted in clinical phase 1 and 2 evaluations, and suggests a clinical role for binimetinib as a therapeutic option for patients with Philadelphia-positive chronic myeloid leukaemia and possibly other BT-positive B-cell chronic lymphoproliferative disorders.
