5. Study Description

Brief Summary
IMAGINE is a Phase II, randomized, two-arm, chemotherapy controlled modular trial in subjects with histologically confirmed, resectable gastric cancer (GC) or adenocarcinoma of the gastroesophageal junction (AEG). Up to 22 patients will be included in each arm of the trial.
Detailed Description
This study will determine the rate of pathological complete responses (pCR) as determined by pathological examination of the resected tumor following preoperative systemic therapy. A pCR rate of 15% is expected with neoadjuvant FLOT chemotherapy. An increase to 35% is estimated to be clinically relevant when patients are treated with either nivolumab in combination with chemotherapy (Arm B) or nivolumab and another immuno-oncology (IO) agent (relatlimab) in Arm D. Additional objectives include resection rate, diseasefree survival (DFS), median overall survival (OS), patient's quality of life (QoL), and safety and tolerability of the treatment. Furthermore, translational endpoints will be investigated.
