A Study of GNC-035, a Tetra-specific Antibody, in Participants With Relapsed/Refractory Hematologic Malignancy

1. The participants could understand and sign the informed consent form, and must participate voluntarily
2. No gender limit
3. Age: ≥18 and ≤75 years old
4. Life expectancy estimated to be at least 3 months
5. Histologically or cytologically confirmed relapsed or refractory non-Hodgkin's lymphoma, relapsed/refractory chronic lymphocytic leukemia, relapsed/refractory acute B-lymphoblastic leukemia, or relapsed/refractory acute myeloid leukemia

6. For relapsed or refractory chronic lymphocytic leukemia (CLL/SLL), specifically:

   • Patients who have relapsed after at least 1 line of standard therapy or who have failed or are intolerant to standard therapy;
   • Patients with relapsed or refractory chronic lymphocytic leukemia who, in the opinion of the investigator, have none or are not suitable/intolerant to other therapies;

7. For other patients with relapsed and refractory non-Hodgkin's lymphoma. These include:

   • Patients in first relapse who still progress during second-line treatment;
   • Patients who relapsed after second-line or multi-line therapy;
   • Refractory patients are defined as those who do not respond or progress after adequate dose and full cycle of standard or current commonly selected combination therapy regimens, and do not respond or progress after replacement of second-line regimens;
   • Relapsed or refractory patients who are judged by the investigator to have no or no indication/intolerance to other therapy.

8. Relapsed or refractory acute B-lymphoblastic leukemia, including:

   • Definition of refractory ALL: failure to achieve CR after standard induction therapy for bone marrow and peripheral blood response;
   • Relapsed ALL is defined as the presence of blasts (> 5%) in the peripheral blood or bone marrow, or the presence of extramedullary disease in patients who have achieved CR; mediastinal enlargement in patients who have achieved CR.
   • Special circumstances: There is no clear classification standard for adult ALL patients with number of relapse ≥ 2, persistent extramedullary leukemia and persistent positive minimal residual disease (MRD). However, most clinical trials classified these patients as refractory cases.
   • Patients with relapsed or refractory acute B-lymphoblastic leukemia who, in the opinion of the investigator, have no or no indication/intolerance to other therapy.

9. Relapsed/refractory acute myeloid leukemia (AML), relapsed/refractory AML is defined as one of the following:

   • Initial treatment who failed to respond to 2 courses of standard regimen;
   • Patients with relapse within 12 months , consolidation and intensive treatment after complete remission;
   • Patients who relapsed after 12 months but failed to respond to conventional chemotherapy;
   • Patients with two or more recurrences;
   • Patients with persistent extramedullary leukemia;
   • Patients with relapsed or refractory acute myeloid leukemia who have no or no indication/intolerance to other therapy as judged by the investigator.
10. Patients with Philadelphia chromosome positive (Ph +) acute lymphoblastic leukemia are eligible if they are intolerant or have failed first and/or second generation tyrosine kinase inhibitors (TKIs); patients with a positive T315I mutation do not require TKI salvage
11. For non-Hodgkin lymphoma, measurable lesions on CT (any lymph node lesion ≥ 1.5 cm in long diameter or > 1.0 cm in long diameter for extranodal lesions) at screening; CLL/SLL: peripheral blood leukemia cells ≥ 5.0 × 109/L; or any lymph node lesion ≥ 1.5 cm in long diameter; WM: IgM 2 × ULN;
12. For patients with acute lymphoblastic leukemia, ≥ 5% lymphoblasts in the bone marrow by morphologic assessment
13. For patients with acute myeloid leukemia, ≥ 5% blasts in the bone marrow by morphologic assessment
14. ECOG Performance Status ≤ 2
15. Recovery from toxicities of prior anticancer therapy to ≤ Grade 1 as defined by NCI-CTCAEv5.0 (except alopecia)

16. The organ function level within 7 days before the first administration meets the following requirements:

    Bone marrow function (only for patients with non-Hodgkin's lymphoma): Neutrophils without blood transfusion, G-CSF (without long-acting whitening needles within 2 weeks) and drug correction within 7 days before screening Absolute count (ANC) ≥1.0×10\^9/L (for subjects with bone marrow infiltration, ≥0.5×10\^9/L); hemoglobin ≥80 g/L (for subjects with bone marrow infiltration, ≥70g /L); Platelet count ≥50×10\^9/L; Liver function: In the case of no hepatoprotective drugs for correction within 7 days before screening, total bilirubin ≤ 1.5 ULN (Gilbert's syndrome ≤ 3 ULN), transaminase (AST/ALT) ≤ 2.5 ULN (tumor invasive changes in the liver) Subject ≤5.0 ULN), and/or alkaline phosphatase ≤5 ULN; Kidney function: creatinine (Cr) ≤ 1.5 ULN or creatinine clearance (Ccr) ≥ 50 mL/min (calculated by the research center); Coagulation function: fibrinogen ≥ 1.5g/L; activated partial thromboplastin time (APTT) ≤ 1.5 × ULN; prothrombin time (PT) ≤ 1.5 × ULN;

17. Female participants with fertility or male participants whose partner(s) are fertile must take effective contraceptive measures from 7 days prior to the first administration to 12 weeks after the administration. Female participants with fertility must have a negative serum/urine pregnancy test in 7 days prior to the first dose.
18. Subjects are capable and willing to comply with the visits, treatment plans, laboratory examinations and other research-related procedures stipulated in the research protocol.
