What side effects are associated with this type of intervention?

Common treatments for melanoma, particularly enzyme inhibitors like binimetinib and encorafenib, often cause side effects such as skin rash, diarrhea, fatigue, and nausea. More severe side effects can include liver toxicity, heart issues, and eye problems. These side effects are typical of targeted therapies that inhibit specific enzymes involved in tumor growth.

What prior FDA approvals exist?

The FDA has approved several enzyme inhibitors for the treatment of melanoma, particularly those targeting the BRAF and MEK pathways. Notable approvals include vemurafenib and dabrafenib, both BRAF inhibitors, and trametinib, a MEK inhibitor. These drugs have shown efficacy in treating BRAF V600 mutation-positive melanoma. The combination of BRAF and MEK inhibitors, such as dabrafenib with trametinib, has also been approved to improve outcomes by targeting different points in the same pathway. These treatments are similar to the investigational combination of binimetinib and encorafenib, which are being studied for their potential to inhibit tumor growth by blocking specific enzymes needed for cell proliferation.

What other types of research exist?

Promising alternatives to Binimetinib and Encorafenib for melanoma patients include: 1) Pembrolizumab and Nivolumab (PD-1 inhibitors), which have shown significant efficacy in melanoma treatment. 2) Combination therapies like Ipilimumab (CTLA-4 inhibitor) with Nivolumab. 3) Targeted therapies such as Dabrafenib and Trametinib for patients with BRAFV600E mutations. These treatments have demonstrated effectiveness in clinical trials and are expected to remain relevant in 2024.

Binimetinib + Encorafenib for Melanoma

Q: What is the mechanism of action of this treatment?

The most common treatments for melanoma, particularly those involving enzyme inhibition, include BRAF and MEK inhibitors like binimetinib and encorafenib. These drugs work by targeting specific enzymes that are involved in the growth and proliferation of melanoma cells. BRAF inhibitors block the activity of the mutated BRAF protein, which is present in about half of melanomas and drives tumor growth. MEK inhibitors, on the other hand, target the MEK enzyme, which is part of the same signaling pathway as BRAF. By inhibiting these enzymes, these treatments can effectively slow down or stop the growth of melanoma cells. This is crucial for melanoma patients as it can lead to better control of the disease, potentially prolonging survival and improving quality of life.

Catheter-related venous thrombosis is not considered a thromboembolic event for this trial even if < 12 weeks prior to starting study treatment. Note: Patients with either deep vein thrombosis or pulmonary emboli that do not result in hemodynamic instability are allowed to enroll as long as they are stable, asymptomatic and on stable anticoagulants for at least 2 weeks. Additionally, patients with thromboembolic events related to indwelling catheters or other procedures may be enrolled Evidence of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection NOTE: Patients with laboratory evidence of cleared HBV or HCV infection may be enrolled NOTE: Patients with no prior history of HBV infection who have been vaccinated against HBV and who have a positive antibody against hepatitis B surface antigen as the only evidence of prior exposure may enroll Pregnancy or breastfeeding or patients who plan to become pregnant during the duration of the study Other severe, acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study treatment administration or that may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient an inappropriate candidate for the study

Summary

This trial studies how well binimetinib and encorafenib work in patients with melanoma that has spread to the brain. These medications may help stop cancer growth by blocking important enzymes. The trial focuses on patients with a specific mutation (BRAFV600) whose cancer has spread to critical areas. Encorafenib and binimetinib are FDA-approved for treating metastatic melanoma with BRAFV600 mutations.

Who is the study for?

Adults with metastatic melanoma that has spread to the brain, including those who have previously received FDA-approved BRAF inhibitors. Participants must have a specific BRAFV600 mutation and be in good enough health as determined by certain lab parameters. Pregnant or breastfeeding individuals are excluded, as well as those with significant heart conditions, infections, gastrointestinal impairments, or a history of certain blood clots.

What is being tested?

The trial is testing binimetinib and encorafenib's effectiveness on melanoma that has reached the central nervous system. These drugs aim to halt tumor growth by inhibiting key enzymes. The study includes patients who've had prior treatments and those new to these medications.

What are the potential side effects?

Potential side effects may include fatigue, skin reactions, vision changes due to eye problems like retinal vein occlusion (RVO), liver enzyme elevations indicating potential liver damage, muscle pain or weakness from neuromuscular issues, high blood pressure, bleeding events and clotting disorders.
