A Study of Precemtabart Tocentecan With or Without Bevacizumab Compared to Trifluridine/Tipiracil Plus Bevacizumab in Participants With Previously Treated Metastatic Colorectal Cancer (PROCEADE-CRC-03)

Официальное название

A Randomized, Open Label, 3-arm Phase 3 Study of Precemtabart Tocentecan With or Without Bevacizumab Compared to Trifluridine/Tipiracil Plus Bevacizumab in Participants With Previously Treated Metastatic Colorectal Cancer (PROCEADE-CRC-03)

Обзор

This study aims to address the unmet medical need of participants with metastatic colorectal cancer (mCRC) who have previously been treated with irinotecan, oxaliplatin, a fluoropyrimidine, and bevacizumab, by demonstrating an overall survival prolongation with precemtabart tocentecan (Precem-TcT) as single agent or Precem-TcT in combination with bevacizumab compared to trifluoride/tipiracil (FTD-TPI) plus bevacizumab.

Вмешательства

• Препарат Precemtabart tocentecan
  Precem-TcT, administered, once every 3 weeks intravenously, on Day 1 of each 21-day cycle.
• Препарат Bevacizumab
  Bevacizumab, administered intravenously every 3 weeks on Day 1 of each 21-day cycle or every 2 weeks on Day 1 and Day 15 of each 28-day cycle.
• Препарат Trifluridine/Tipiracil (FTD-TPI)
  FTD-TPI, tablet, administered orally twice daily, on Days 1 to 5 and Days 8 to 12 of each 28-day cycle.
