phase i clinical study of gnc-038 in patients with non-hodgkin's lymphoma or acute lymphoblastic leukemia

Conditions: Non Hodgkin Lymphoma; Acute Lymphoblastic Leukemia

Summary: an open, multicenter, phase i clinical study to evaluate the safety, tolerability, pharmacokinetics/pharmacokinetics, and antitumor activity of gnc-038 quad-specific antibody injection in relapsed or refractory non-hodgkin's lymphoma, relapsed or refractory acute lymphoblastic leukemia, and refractory or metastatic solid tumors.

phase ia: to observe the safety and tolerability of gnc-038 in patients with relapsed or refractory non-hodgkin lymphoma (r/r nhl)/relapsed or refractory acute lymphoblastic leukemia (r/r all), to determine the maximum tolerated dose (mtd) or maximum administration dose (mad) and dose-limiting toxicity (dlt) of gnc-038 without mtd and recommend the dose for subsequent clinical studies. phase ib: to further observe the safety and tolerability of gnc-038 at the phase ia recommended dose to determine the phase ii recommended dose (rp2d).

renal function: creatinine (cr) ≤1.5 uln and creatinine clearance (ccr) ≥50 ml/min (based on the center's calculation criteria). the investigators judged renal function intact without injury, except that abnormal creatinine index was caused by tumor. coagulation function: fibrinogen ≥1.5g/l;
