The goal of this interventional clinical trial is to provide proof-of-principle data for the biologic activity of defactinib in combination with avutometinib in brain metastases from melanoma, and to define the potential role of the combination with mutant BRAF inhibitors or after BRAF/MEK inhibitors in BRAF V600E/K mutant tumors, in individuals with advanced melanoma who experience the development or progression of brain metastases after treatment with immune checkpoint inhibitors.
The main questions it aims to answer are:
* What is the preliminary response rate of defactinib and avutometinib in patients with RAS mutant, BRAF mutant, NF1 mutant, triple RAS/BRAF/NF1 wild type (wt) melanoma (including RAF fusions)? * What is the safety and tolerability of the combination of defactinib, avutometinib, and encorafenib in patients with BRAF V600E/K mutant melanoma with at least one untreated brain metastases? * What is the preliminary response rate of the three drug combination of defactinib, avutometinib, and encorafenib in patients with BRAF V600E/K mutant melanoma.
