What is the purpose of this trial?

This trial tests treatments for melanoma, a type of skin cancer, by evaluating whether a combination of the drugs encorafenib (Braftovi) and binimetinib (Mektovi) can reduce cancer recurrence after surgery. Researchers aim to understand the effectiveness of these drugs when administered before and after surgery, based on the cancer's response. Participants whose cancer does not fully respond initially might also receive a different drug, nivolumab (Opdivo). The trial seeks participants with melanoma that has a specific genetic mutation called BRAFV600, which influences cancer growth. As an Early Phase 1 trial, this research focuses on understanding the treatment's effects in people, offering participants the chance to contribute to groundbreaking research.

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify if you must stop taking your current medications, but it mentions that you cannot use certain prohibited medications, including some herbal supplements and foods, within one week before starting the study treatment. It's best to discuss your current medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that patients generally tolerate the combination of encorafenib and binimetinib well. In one study, only 0.5% of patients experienced a noticeable increase in heart rhythm, indicating that serious heart-related side effects are rare.

For nivolumab, studies have found that its safety remains consistent, regardless of dosage, meaning side effects are usually predictable and manageable.

In summary, both treatments have some side effects, but they are typically mild and controllable. This information is based on past studies, so discussing any concerns with a healthcare provider is always advisable. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about using encorafenib and binimetinib for melanoma because they target specific mutations in cancer cells, potentially offering a more precise approach than traditional chemotherapy. Encorafenib is a BRAF inhibitor, while binimetinib inhibits MEK, both of which are parts of a pathway that often contributes to melanoma growth. This dual-targeted approach aims to effectively halt cancer progression by disrupting the cancer's growth signals, which is different from standard treatments like immunotherapy with drugs such as nivolumab or traditional chemotherapy. Additionally, the combination's ability to continue treatment after surgery, based on the tumor's response, offers a tailored treatment plan that could improve outcomes for patients.

What evidence suggests that this trial's treatments could be effective for melanoma?

Research has shown that using the drugs encorafenib and binimetinib together can effectively treat melanoma, a type of skin cancer. One study found that patients taking these drugs lived for a median of 36.8 months specifically due to melanoma. Additionally, 69.4% of patients experienced tumor reduction or disappearance after treatment. In this trial, participants who achieve a pathologic complete response will continue with encorafenib and binimetinib. For those whose cancer does not completely respond, the trial offers another option: the drug nivolumab. Previous studies have shown that nivolumab can improve survival rates, with 44% of patients living for at least five years when used alone. These treatments offer promising options for managing melanoma. ^{2 3 6 7 8}

Published Research Related to This Trial

In a phase II study involving 98 patients with BRAFV600E-mutant metastatic non-small-cell lung cancer (NSCLC), the combination of encorafenib and binimetinib achieved a confirmed objective response rate of 75% in treatment-naïve patients and 46% in previously treated patients, indicating significant efficacy.

The treatment was generally well-tolerated, with common side effects including nausea (50%) and diarrhea (43%), but it also led to dose reductions in 24% of patients and one serious adverse event of intracranial hemorrhage, highlighting the importance of monitoring safety.

Phase II, Open-Label Study of Encorafenib Plus Binimetinib in Patients With BRAFV600-Mutant Metastatic Non-Small-Cell Lung Cancer. Riely, GJ., Smit, EF., Ahn, MJ., et al.[2023]

A 56-year-old woman experienced transient visual symptoms, including blurry vision and colored halos, after starting Encorafenib/Binimetinib for metastatic melanoma, indicating potential retinal side effects of the treatment.

Despite the initial symptoms being linked to subretinal fluid (SRF), the patient later experienced similar visual disturbances without any detectable SRF, suggesting that Binimetinib may cause intermittent visual symptoms even after fluid resolution.

The combination of encorafenib and binimetinib for treating BRAF-mutant advanced melanoma shows similar efficacy to existing treatments like dabrafenib+trametinib and vemurafenib+cobimetinib, based on clinical trial results.

This new combination has a lower incidence of certain side effects, such as pyrexia and photosensitivity, which can significantly improve the quality of life for patients.

The combination of encorafenib and binimetinib has shown a median overall survival of 33.6 months in patients with advanced BRAFV600 mutation-positive melanoma, outperforming other BRAF/MEK inhibitor combinations that achieved 22 months.

Encorafenib's unique pharmacokinetics allow for prolonged binding and greater BRAF inhibition, which may lead to improved efficacy and better tolerability, with fewer side effects like pyrexia and photosensitivity.

Encorafenib and binimetinib, a combination of a BRAF inhibitor and a MEK inhibitor, received FDA approval in June 2018 for treating patients with unresectable or metastatic melanoma that has specific BRAF mutations (V600E or V600K).

The combination therapy is also being explored in ongoing phase III clinical trials for metastatic colorectal cancer, indicating its potential broader application beyond melanoma.

In the COLUMBUS trial involving 577 patients with BRAFV600-mutant melanoma, the combination of encorafenib and binimetinib significantly improved overall survival (33.6 months) compared to vemurafenib (16.9 months), indicating a strong efficacy of the combination therapy.

The safety profile of encorafenib plus binimetinib was acceptable, with common grade 3 or 4 adverse events being manageable, suggesting that this combination therapy is a promising treatment option for patients with this type of melanoma.

In a 5-year study of patients with advanced BRAF V600-mutant melanoma, those treated with the combination of encorafenib and binimetinib (COMBO group) had a longer duration of survival without disease progression compared to those receiving either encorafenib alone or vemurafenib.

The combination treatment also resulted in fewer patients needing additional anticancer therapies after treatment, and while side effects were similar across all groups, they decreased over time for the COMBO group.

In the COLUMBUS study involving 577 patients with advanced BRAF-mutant melanoma, the combination treatment of encorafenib plus binimetinib significantly improved health-related quality of life (HRQoL) scores compared to vemurafenib, indicating a meaningful enhancement in patients' perceived health status.

Patients receiving the combination therapy also experienced a delay in deterioration of quality of life, suggesting that this treatment not only improves survival but also helps maintain a better quality of life during treatment.

Encorafenib and binimetinib are effective small-molecule inhibitors that target the BRAF and MEK proteins in the MAPK signaling pathway, significantly improving overall and progression-free survival in patients with metastatic melanoma harboring BRAF V600 mutations.

This combination therapy received FDA approval in June 2018 specifically for treating melanoma with BRAF V600E/K mutations, highlighting its clinical utility and relevance in modern cancer treatment.
