First-Line Immunotherapy Versus Targeted Therapy in Patients With BRAF -Mutant Advanced Melanoma: A Real-World Analysis

Aim: To compare effectiveness of nivolumab + ipilimumab (NIVO + IPI) versus BRAF + MEK inhibitors (BRAFi + MEKi) in patients with BRAF-mutant advanced melanoma in the real-world setting. Materials & methods: This study used the Flatiron Health electronic medical record database. Results: After adjusting for differences in baseline characteristics, NIVO + IPI was associated with a 32% reduction in risk of death versus BRAFi + MEKi. At a mean follow-up of 15–16 months, 64% of NIVO + IPI patients and 43% of BRAFi + MEKi patients were alive; subsequent therapy was administered to 33 and 41% of patients, respectively. After first-line NIVO + IPI, 20% of patients died before subsequent therapy, whereas 32% died after first-line BRAFi + MEKi. Conclusion: In this real-world study, patients treated with first-line NIVO + IPI showed significant survival benefit versus those receiving first-line BRAFi + MEKi.
