Summary

This trial will compare how safe and effective a drug called sacituzumab tirumotecan is compared to the usual treatment in patients with advanced stomach or esophageal cancer. The main goal

Who is the study for?
This trial is for adults with advanced or metastatic gastroesophageal adenocarcinoma who have tried at least two prior treatments. They must be able to perform daily activities with little to no assistance (ECOG status 0-1), swallow pills, and have tumors that can be measured by scans. Their organs should function well, and they need a specific protein on their cancer cells (TROP2) which will be tested.Check my eligibility
What is being tested?
The study tests Sacituzumab Tirumotecan against doctors' choice of standard treatments like Docetaxel, Irinotecan, Paclitaxel, or Trifluridine-Tipiracil in patients with gastroesophageal cancer. The main goal is to see if Sacituzumab Tirumotecan helps patients live longer compared to the other drugs.See study design
What are the potential side effects?
Sacituzumab Tirumotecan may cause side effects such as nausea, diarrhea, low blood cell counts leading to increased infection risk or bleeding problems, fatigue, hair loss and allergic reactions. Side effects vary based on individual patient responses.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Sacituzumab tirumotecanExperimental Treatment1 Intervention
Participants will receive sacituzumab tirumotecan at a dose of 4mg/kg by intravenous (IV) infusion on days 1, 15, and 29 of every 42-day cycle.
Group II: Treatment of Physician's Choice (TPC)Active Control4 Interventions
TPC include either trifluridine-tipiracil (35 mg/m^2 orally (PO) twice a day (BID) on days 1 to 5 and 8 to 12 of every 28-day cycle), irinotecan (150 mg/m^2 IV on days 1 and 15 of every 28-day cycle), paclitaxel (80 mg/m^2 IV on days 1, 8, and 15 of every 28-day cycle), or docetaxel (75 mg/m^2 IV on day 1 of every 21-day cycle).
