median OS with current single-agent immunotherapy ± chemotherapy regimens in patients with PD-L1 ≥50%, based on results of clinical trials.2,4,9#
|| Based on ORR from 4 randomized phase 3 studies of 1L mNSCLC in patients without AGAs treated with a PD-1 or PD-L1 inhibitor.9-12
¶ As seen in 243 patients with mNSCLC who initially responded to anti–PD-1 treatment at Memorial Sloan Kettering Cancer Center from April 2011 to December 2017. Acquired resistance was defined as partial or complete response followed by isolated or systemic progression on or before the date of last scan.13
#Based on the 5-year follow-ups of 3 randomized phase 3 studies of 1L mNSCLC in patients without AGAs treated with a PD-1 inhibitor ± chemotherapy.2,4,9

EMERGING POTENTIAL
Powering possibilities in mNSCLC with TROP-215
TROP-2, a proven target in multiple cancers, is a calcium signal transducer involved in several signaling pathways related to:
- Cell proliferation through cyclins and cyclin-dependent kinases
- Invasion and metastasis via matrix metalloproteinases and other proteins
- Cell survival by degradation of FOXO3a
TROP-2 is expressed in 89% to 100% of NSCLC, regardless of tumor histology or presence of actionable alterations.16-18
