Original description

This trial is a multicenter, open-label, single-arm, dose-escalation and dose-expansion clinical trial. The dose was increased according to the "3 + 3" rule. Patients with previously untreated patients with CD20-positive DLBCL were selected to evaluate the safety, tolerance (DLT, MTD), pharmacokinetics, and anti-tumor activity of TRS005 in combination with standard doses of cyclophosphamide, doxorubicin, and prednisone（T-CHP） by intravenous drip every 3 weeks.Read full original descriptionShow less
