Abstract Text | Radiation's confounding and adverse effects on tumor microenvironment and normal brain could potentially be delayed by upfront combination treatment. We present a patient with newly diagnosed BRAFV600E-mutant, PD-L1-positive glioblastoma treated with off-label RAF/MEK inhibitors encorafenib/binimetinib after progressing on postoperative immune checkpoint blockade and temozolomide (no radiation administered: NCT03425292). Complete response occurred 6 months after adding encorafenib/binimetinib, and clinical benefit was sustained for over 20 months. Treatment was well tolerated with manageable toxicities, with quality of life and cognitive function maintained throughout treatment. Adding encorafenib/binimetinib to immunotherapy and temozolomide conferred favorable and lasting efficacy for our BRAFV600E -mutant glioblastoma patient, justifying future studies. |

BRAF V600E CD274 pos | glioblastoma | predicted - sensitive | Binimetinib + Encorafenib + Nivolumab + Temozolomide | Case Reports/Case Series | Actionable | In a clinical case study, the addition of Mektovi (binimetinib) and Braftovi (encorafenib) to treatment with the combination of Opdivo (nivolumab) and Temodar (temozolomide) resulted in a complete response after 6 months in a patient with CD274 (PD-L1), PDCD1 (PD-1)-positive glioblastoma harboring BRAF V600E, and the patient remained progression-free for at least 20 months while on treatment (PMID: 39036436). | 39036436 |
