In a post-hoc analysis of 40 patients, Lumakras achieved a 77.5% disease control rate (DCR), similar to patients without brain metastases.
A median progression-free survival (PFS) of 5.3 months and median overall survival (OS) of 8.3 months were observed.
In patients evaluable by Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria, 14 of 16 patients (88%) maintained intracranial disease control of their stable brain lesions during Lumakras therapy with two achieving complete responses of non-target lesions.
The safety profile of Lumakras in the brain metastases group was consistent with previous reports.
