Purpose

Varlitinib is a pan-human epidermal growth factor receptor (HER) inhibitor targeting epidermal growth factor receptor (EGFR), HER2, and HER4. We present a phase Ib/II study of a combination of varlitinib and weekly paclitaxel as a second-line treatment for patients with EGFR/HER2 co-expressing advanced gastric cancer (AGC).

Result

Genomic alteration landscape in circulating tumor DNA analysis according to the progression-free survival (PFS), overall survival (OS), and EGFR/HER2 immunohistochemical expression (n=15).

Conclusion

A combination of varlitinib and paclitaxel displayed manageable toxicity and modest antitumor activity in patients with EGFR/HER2 co-expressing AGC who progressed after first-line chemotherapy.

Method

The circulating tumor DNA (ctDNA) was extracted from the patient’s plasma (10 mL) at two time points (before treatment and at the first response evaluation or end of the treatment). The DNA NGS library and solution-based target enrichment were performed at IMBdx, Inc. (Seoul, Korea), using AlphaLiquid100. The captured DNA libraries were sequenced using the Illumina NovaSeq 6000 platform (Illumina, San Diego, CA) in the 2×150 bp paired-end mode.
