Trial Parameters
Brief Summary
This is a non-randomized, open-label, dose-escalation and dose-expansion phase I/II clinical study to evaluate the safety, tolerability, and efficacy of HCB101 in combination with Cetuximab/Bevacizumab, and FOLFOX/FOLFIRI in Advanced or Metastatic Colorectal Cancer. The trial consists of two phases: the dose-escalation phase (I) and the dose-expansion phase (II). Subjects will receive a weekly single dose of HCB101 IV infusion over 60 (±10) minutes on Days 1, 8, and 15 in each 21-day cycle in combination with Bevacizumab (5 mg/kg IV day 1; given every 14 days) /Cetuximab (500 mg/m2 IV day 1; given every 14 days) , and FOLFIRI/FOLFOX until unacceptable AE(s), radiographic or clinically documented disease progression, withdrawal of consent, loss to follow-up, death, or termination of the study whichever occurs first.
