Competitive Landscape

First-line advanced NSCLC is an immuno-oncology duopoly with Keytruda (pembrolizumab, Merck) as the clear anchor, generating $29.5B in 2024 worldwide sales per Merck's 10-K with NSCLC the single largest contributing indication. Anti-PD-1 mAbs (direct competitor class): Opdivo (nivolumab, BMS) holds non-squamous and squamous 2L monotherapy plus the Opdivo+Yervoy chemo-limited regimen in 1L (CheckMate-9LA, -227); Libtayo (cemiplimab, Regeneron/Sanofi) is approved in PD-L1-high monotherapy. Anti-PD-L1 mAbs: Tecentriq (atezolizumab, Roche) is approved in 1L combinations (IMpower150) and adjuvant resected stage II-IIIA; Imfinzi (durvalumab, AstraZeneca) dominates unresectable stage III post-chemoradiation (PACIFIC) and has 2024 global sales ~$4.7B across indications. CTLA-4 combinations: Imjudo (tremelimumab) + Imfinzi received 1L metastatic NSCLC approval per POSEIDON. Targeted-therapy segment (separate from IO but competing for patient share): Tagrisso (osimertinib, AstraZeneca) dominates EGFR+, Alecensa/Lorbrena in ALK+, Krazati/Lumakras in KRAS G12C. Commercial threat assessment: Keytruda's 1L pembro+chemo regimen (KEYNOTE-189/407) remains the dominant global first-line choice across PD-L1 strata; biosimilar entry post-2028 LOE and emerging PD-1/VEGF bispecifics (ivonescimab, Summit/Akeso per HARMONi-2 Chinese registration) are the medium-term threats.
