Title:
BIOMARKER-GUIDED ENRICHMENT OF THE ANTITUMOR ACTIVITY OF MARGETUXIMAB (M) PLUS PEMBROLIZUMAB (P) IN PATIENTS WITH ADVANCED HER2+ GASTRIC ADENOCARCINOMA (GEA)
Excerpt:
The presence of ERBB2 amplification by ctDNA and tumor PD-L1 expression by IHC were both associated with increased probability of OR: 33.3% v. 10.5% (p = 0.0948) and 43.8% v. 16.7% (p = 0.0769), respectively. ORR was 5 of 8 (62.5%) in ERBB2 amplified/PD-L1+ pts
