A Study of GNC-035 in Relapsed or Refractory Non-Hodgkin 's Lymphoma and Other Hematological Malignancies

An Open, Multicenter, Phase I / II Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics / Pharmacodynamics and Antitumor Activity of GNC-035 Tetra-specific Antibody Injection in Relapsed or Refractory Non-Hodgkin 's Lymphoma and Other Hematological Malignancies

Phase I main objectives: To observe the safety and preliminary efficacy of GNC-035 in patients with relapsed/refractory non-Hodgkin lymphoma and other hematological malignancies, to determine the DLT and MTD, or MAD, and to determine RP2D. Phase II Main objective: To explore the efficacy of GNC-035 in patients with relapsed/refractory non-Hodgkin lymphoma and other hematological malignancies.
