Eligible pts had advanced KRAS-mutated NSCLC and were receiving first-line PD-1 inhibitor-based therapy. Pts were treated with PD-1 inhibitor (q3w) and denosumab (120 mg, q4w) for subsequent maintenance therapy regardless of bone metastases….Subgroup analysis suggested a greater survival benefit in patients with KRAS G12C mutation than in patients with KRAS non-G12C mutation (mPFS1, p=0.026; mPFS2, p=0.049).
