A Study of GNC-038 Injection in Patients With Relapsed or Refractory Non-Hodgkin's Lymphoma

An Open, Multicenter, Phase Ib/II Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Antitumor Activity of Tetra-specific Antibody GNC-038 Injection in Patients With Relapsed or Refractory Non-Hodgkin's Lymphoma (NHL)

To explore the safety and preliminary efficacy of GNC-038 in patients with relapsed or refractory NHL, and to determine the MTD and RP2D of GNC-038, or the MAD and DLT

phase Ib: To explore the safety and preliminary efficacy of GNC-038 in patients with relapsed or refractory NHL, and to determine the MTD and RP2Dof GNC-038, or the MAD and DLT of GNC-038 if MTD is not reached, by intravenous infusion (IV, QW) once a week (2 weeks as a cycle) phase II To explore the efficacy of GNC-038 in patients with relapsed or refractory non-Hodgkin's lymphoma
