Brief Summary:
A Phase 2/3 Study of Evorpacept (ALX148) in Combination With Trastuzumab, Ramucirumab, and Paclitaxel in Patients With Advanced HER2-overexpressing gastric/GEJ adenocarcinoma.

Condition or disease Intervention/treatment Phase
Gastric Cancer Gastroesophageal Junction Adenocarcinoma Gastric Adenocarcinoma Drug: Evorpacept (ALX148) Drug: Trastuzumab Drug: Ramucirumab Drug: Paclitaxel Phase 2 Phase 3

Detailed Description:
This is a randomized phase 2 (open-label) / 3 (double-blind), international, multi-center study of patients with metastatic HER2-overexpressing gastric/GEJ adenocarcinoma that has progressed on or after prior HER2-directed therapy and fluoropyrimidine- or platinum-containing chemotherapy and are suitable for chemotherapy (2nd-line or 3rd-line). Approximately 450 adult patients are expected to be enrolled in the study across both phases.
