Everolimus resulted in significant improvement in PFS for p16-negative patients (n=31) (P=0.031; HR=0.26, 95% CI: 0.07-0.97)...Further, PFS was significantly higher in TP53 mutated (TP53mut) patients treated with everolimus compared to placebo (Log-Rank P=0.027; HR=0.24, 95% CI: 0.06-0.95)....p16-negative and TP53mut patients may benefit from adjuvant treatment with everolimus.
