Title:
327/2-Antitumor efficacy of trastuzumab deruxtecan in combination with adavosertib in HER2-expressing Cyclin E amplified gastroesophageal cancers
Published date:
03/09/2022
Excerpt:
T-DXd induced durable tumor regression in two HER2 amplified and HER2 overexpressing gastroesophageal PDX cancer models with HER2 amplification/3+ overexpression and concomitant cyclin E amplification/expression. Adavosertib enhanced the antitumor activity of T-DXd in two HER2 low, cyclin E amplified gastroesophageal cancer PDX models (one with an ERBB2 G778A mutation).
