Approximately 70% of newly-diagnosed NSCLC cases occur in the elderly, and more than half are locally advanced/metastatic. We present a pooled analysis of efficacy and safety in elderly pts (aged ≥75 y) enrolled in 3 randomized controlled trials of pembro monotherapy vs standard chemotherapy (chemo) for PD-L1–positive advanced NSCLC.


Pts were aged ≥18 y with advanced NSCLC with PD-L1 tumor proportion score (TPS) ≥1% (KEYNOTE-010, -042) or TPS ≥50% (KEYNOTE-024). In KEYNOTE-010, pts were randomized to pembro 2 or 10 mg/kg Q3W or docetaxel, as second- or later-line therapy. In KEYNOTE-024 and -042, pts were randomized to first-line pembro 200 mg Q3W or platinum-based chemo. OS was estimated by the Kaplan-Meier method.


The 3 trials included 264 pts aged ≥75 (range, 75–90) y with TPS ≥1%; 132 pts had TPS ≥50%. Independent of line of treatment, HRs (95% CI) for OS favored pembro vs chemo: 0.76 (0.56–1.02) in pts with TPS ≥1% and 0.40 (0.25–0.64) in pts with TPS ≥50%. Pembro also improved OS vs chemo in the pooled analysis of pts with TPS ≥50% who received first-line therapy (KEYNOTE-024 and -042): HR, 0.41 (95% CI, 0.23–0.73). Overall, fewer treatment-related AEs across various categories were observed with pembro vs chemo, in particular, grade 3–5 treatment-related AEs in pts aged ≥75 y (Table). Immune-mediated AEs and infusion reactions were more frequent with pembro vs chemo, with similar frequency in pts receiving pembro aged ≥75 y and <75 y (Table).


In this pooled analysis of pts aged ≥75 y with PD-L1–positive advanced NSCLC, pembro monotherapy improved OS vs chemo, both in pts with PD-L1 TPS ≥1% and PD-L1 TPS ≥50%. The safety profile of pembro was similar in pts aged ≥75 y and <75 y, with lower rates of grade 3–5 treatment-related AEs vs chemo.
