Abstract 399P

Background

Pts with NSCLC and MET exon 14 skipping (METex14; 3–4%) or MET amplification (METamp; 1–2%) have not been well characterized; this study aimed to address this gap.

Methods

This non-interventional descriptive cohort study used real-world data extracted from electronic medical records from academic oncology centers in Israel, The Netherlands, Taiwan, and the USA. Pts had confirmed diagnosis of advanced (stage IIIB–IV) NSCLC (date of diagnosis=index date) between 1 Jan 2010 and 30 Sept 2018 and MET alterations. Medical history was assessed prior to and at the index date (baseline period) and outcomes from first date of treatment to death, loss to follow-up, or end of the study period.

Results

70 pts had METex14 tumors and 47 pts had METamp tumors; testing methods were heterogenous. Concomitant oncogenic mutations were more common in METamp than METex14 pts; 9% of METex14 pts had concomitant METamp. Records of systemic therapy for advanced disease were available for 58 (83%) pts in the METex14 cohort and 36 (77%) pts in the METamp cohort. Common treatments (METex14 vs METamp) were platinum-based therapy (1st line [1L], 44 vs 41%; 2nd line [2L], 35 vs 30%) and MET inhibitor monotherapy (1L, 33 vs 29%; 2L, 30 vs 39%). Immune checkpoint inhibitors (±chemotherapy) were used across 1L (13 vs 16%) and 2L (35 vs 13%). Median (95% CI) time to next treatment or death was 6.3 months (4.8, 10.9) for 1L (n=52) and 7.8 months (3.9, 11.3) for 2L (n=23) in the METex14 cohort and 9.0 months (6.1, 11.7) for 1L (n=34) and 5.1 months (3.3, 12.8) for 2L (n=23) in the METamp cohort. Median (95% CI) overall survival from start of 1L therapy (any) was 12.0 months (6.8, 19.2) in METex14 and 22.0 months (9.8, 31.2) in the METamp cohort Table: 399P

Patient records were from Israel (n=18), The Netherlands (n=13), Taiwan (n=23), and the USA (n=63). *Data on brain metastases were available for 52 pts in the METex14 cohort and 28 pts in the METamp cohort.

Conclusions

Heterogeneous treatments reflect the changing landscape and availability of new treatments, as well as the high unmet medical need in pts with METex14 who were older and had more advanced disease at diagnosis. Screening for these alterations in pts with advanced NSCLC is warranted.
