The presentation highlights results from the OptimUM-01 study evaluating darovasertib + crizotinib as first-line treatment for metastatic uveal melanoma, showing improved median overall survival (21.1 months) and higher response rates compared with historical standard therapies. The combination demonstrated a manageable safety profile, supporting its continued evaluation in the ongoing registrational OptimUM-02 trial.

For patients with BRAF-mutated melanoma with asymptomatic brain metastases, immunotherapy, particularly the combination of ipilimumab and nivolumab, is the preferred treatment option due to its effectiveness and durability, as supported by the seven-year follow-up data from the CHECKMATE 204 trial.

Panelists discuss the potential benefits of rechallenging patients with BRAF-mutated metastatic melanoma with BRAF/MEK inhibitors after a break from treatment, especially for those who initially responded well, and emphasizing the success of this approach in some cases, while highlighting the importance of monitoring and utilizing ctDNA tracking for more informed decision-making.

The 7-year follow-up data for encorafenib/binimetinib showing that around 21% of patients remained progression-free supports BRAF/MEK inhibition as a later treatment option after immunotherapy failure, but doctors are reluctant to stop BRAF/MEK inhibitors given lack of data, even in those patients doing well long-term on the medications with minimal toxicity.

For patients with BRAF-mutant metastatic melanoma, doctors assess symptoms and disease status to determine if they should start treatment with combination immunotherapy, or 8-12 weeks of BRAF/MEK targeted therapy before switching to immunotherapy, which offers the possibility of durable responses or cure.

The panelists emphasize the importance of obtaining tissue for BRAF-mutation testing and dedicated tissue tracking in patients with metastatic melanoma, with immunohistochemistry followed by confirmatory next-generation sequencing, and discuss the promise of liquid biopsies like ctDNA as a future biomarker tracking modality.

When a patient with metastatic melanoma patient tests negative for the BRAF V600E mutation, doctors recommend sending the sample for next-generation sequencing testing which can take 2-3 weeks, during which time they may start immunotherapy if the patient has aggressive disease, but ideally should wait for results to guide treatment.
