Trial Summary

What is the purpose of this trial?

This study is to provide access for patients who are receiving treatment with dabrafenib and/or trametinib in a Novartis-sponsored Oncology Global Development, Global Medical Affairs or a former GSK-sponsored study who have fulfilled the requirements for the primary objective, and who are judged by the investigator as benefiting from continued treatment in the parent study as judged by the Investigator at the completion of the parent study.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on continuing treatment with dabrafenib and/or trametinib for those already on these medications.

What data supports the effectiveness of the drug combination Dabrafenib and Trametinib for cancer treatment?

Research shows that the combination of Dabrafenib and Trametinib is effective in treating advanced melanoma with a specific BRAF mutation, leading to longer survival and better response rates compared to using each drug alone. This combination also shows promise in patients with brain metastases and is generally well tolerated. ^{1 2 3 4 5}

Is the combination of Dabrafenib and Trametinib safe for humans?

The combination of Dabrafenib and Trametinib has been shown to be generally safe in humans, with most side effects being mild or moderate and manageable. Common side effects include fever, increased liver enzymes, swelling, and cold-like symptoms, but the combination therapy tends to have fewer skin-related side effects compared to Dabrafenib alone. ^{1 4 6 7 8}

How is the drug combination of Dabrafenib and Trametinib unique for treating cancer?

The combination of Dabrafenib and Trametinib is unique because it targets the MAPK pathway by inhibiting both BRAF and MEK proteins, which helps in treating cancers with BRAF mutations, like melanoma, more effectively than using either drug alone. This combination has shown to improve survival rates and reduce skin-related side effects compared to other treatments. ^{1 4 6 9 10}

Findings from Research

Dabrafenib and trametinib, both targeting the MAPK pathway, have shown significant efficacy in treating BRAF-mutant metastatic melanoma, with dabrafenib achieving a 59% objective response rate and improved progression-free survival compared to traditional chemotherapy.

The combination of dabrafenib and trametinib resulted in higher response rates and longer median progression-free survival than dabrafenib alone, while also presenting less cutaneous toxicity, making it a promising treatment option for patients.

Dabrafenib and trametinib, alone and in combination for BRAF-mutant metastatic melanoma. Menzies, AM., Long, GV.[2022]

In a study of 78 BRAF inhibitor-naive patients with BRAF V600 mutation-positive metastatic melanoma treated with dabrafenib and trametinib, the median overall survival was over 2 years, with 72% of patients alive at 1 year and 47% at 3 years.

Approximately 20% of patients were progression-free at 3 years, with better outcomes associated with having fewer than three organ metastases and lower baseline lactate dehydrogenase levels, suggesting these factors may help predict durable responses.

Overall Survival and Durable Responses in Patients With BRAF V600-Mutant Metastatic Melanoma Receiving Dabrafenib Combined With Trametinib. Long, GV., Weber, JS., Infante, JR., et al.[2022]

In a study of 66 patients with metastatic BRAF-mutated melanoma treated with dabrafenib and trametinib, 15 patients achieved a complete response (CR), indicating a significant survival benefit from this treatment.

The likelihood of achieving a complete response was higher in patients with smaller lesions (39.3% CR rate) compared to those with larger lesions (10.5% CR rate), suggesting that lesion size and the number of metastatic sites are important factors in treatment outcomes.

BRAFi/MEKi in patients with metastatic melanoma: predictive factors of complete response. Ribero, S., Malavenda, O., Fava, P., et al.[2019]

The combination of dabrafenib and trametinib significantly improves progression-free survival and overall survival in patients with unresectable or metastatic melanoma with a BRAF (V600E/K) mutation, compared to monotherapy with dabrafenib or vemurafenib, based on results from two large phase III studies.

This combination therapy is well-tolerated, showing no increase in overall toxicity compared to monotherapy, and results in fewer skin-related adverse events, likely due to reduced activation of the MAPK pathway.

Dabrafenib plus Trametinib: a Review in Advanced Melanoma with a BRAF (V600) Mutation. Dhillon, S.[2022]

In a compassionate-use setting involving 271 patients with BRAF V600-mutant unresectable or metastatic melanoma, the combination of dabrafenib and trametinib demonstrated a high overall response rate of 67.3% and a median overall survival of 20.0 months for BRAFi-naive patients.

The treatment was well tolerated with no new safety concerns, showing significant clinical activity even in patients with brain metastases, indicating its effectiveness across different treatment lines.

Dabrafenib plus trametinib is effective in the treatment of BRAF V600-mutated metastatic melanoma patients: analysis of patients from the dabrafenib plus trametinib Named Patient Program (DESCRIBE II). Atkinson, V., Sandhu, S., Hospers, G., et al.[2023]

Dabrafenib is an effective treatment for unresectable or metastatic melanoma in patients with the BRAF V600E mutation, which is present in about 50% of malignant melanomas, and has received approval in the US and a positive opinion in the EU.

Ongoing studies are exploring dabrafenib's use both as a standalone treatment and in combination with trametinib, as well as its potential for treating other cancers like colorectal and non-small cell lung cancers, particularly in patients with BRAF V600E/K mutations.

Dabrafenib: first global approval. Ballantyne, AD., Garnock-Jones, KP.[2021]

The combination of dabrafenib and trametinib showed promising antitumor activity in Japanese patients with BRAF V600E/K mutant melanoma, with an overall response rate of 83% in both phase 1 and phase 2 of the study involving 12 patients.

The treatment was generally well-tolerated, with common adverse events including fever (75%) and increased liver enzymes (67%), indicating that while effective, monitoring for side effects is important.

Phase 1/2 study assessing the safety and efficacy of dabrafenib and trametinib combination therapy in Japanese patients with BRAF V600 mutation-positive advanced cutaneous melanoma. Yamazaki, N., Tsutsumida, A., Takahashi, A., et al.[2018]

A validated assay was developed to simultaneously measure the levels of dabrafenib and trametinib in human plasma, which is crucial for therapeutic drug monitoring in patients with BRAF V600 mutation positive melanoma.

The assay demonstrated high accuracy and precision, with results meeting US FDA and EMA guidelines, ensuring reliable monitoring of these medications in cancer treatment.

Simultaneous quantification of dabrafenib and trametinib in human plasma using high-performance liquid chromatography-tandem mass spectrometry. Nijenhuis, CM., Haverkate, H., Rosing, H., et al.[2017]

Dabrafenib demonstrated significant clinical activity in patients with BRAF(V600E/K) mutation-positive metastatic melanoma, with a 59% overall response rate in the BRAF(V600E) group and a median overall survival of 13.1 months.

The treatment was generally well tolerated, with common side effects including arthralgia and hyperkeratosis, and baseline circulating cell-free DNA (cfDNA) levels were found to predict treatment response and progression-free survival.

Phase II trial (BREAK-2) of the BRAF inhibitor dabrafenib (GSK2118436) in patients with metastatic melanoma. Ascierto, PA., Minor, D., Ribas, A., et al.[2022]

The combination of dabrafenib and erlotinib significantly enhances the inhibition of cell proliferation, colony formation, and migration in BRAF-mutated anaplastic thyroid carcinoma (ATC) cells, compared to using either drug alone.

This combination treatment also effectively suppresses tumor growth and induces apoptosis in an in vivo xenograft model, suggesting it could be a promising strategy to overcome resistance to dabrafenib in patients with BRAF-mutated ATC.
