Study Arms (1)
RC1012 injection (allo-DNT Cells)
EXPERIMENTALExperimental: RC1012 injection (allo-DNT Cells) The trial is divided into two parts: Part A1 is a single- dose escalation trial with three dose groups (5×10\^7 cells/kg, 1.5×10\^8 cells/kg, 4.5×10\^8 cells/kg), with 9-18 patients planned to be enrolled. Part A2 is a multiple-dose escalation trial consisting of 2 dose groups (1.5×10\^8 cells/kg and 4.5×10\^8 cells/ kg at day 0, day 7 and day 14), with 9-12 patients planned to be enrolled. Part B is a multiple-dose extension trial in which the Safety Review Committee evaluates whether to extend an additional 3-6 patients to receive the multiple cell infusions based on available PK and safety data.
Interventions
RC1012 injection (allo-DNT cells) from healthy donors and have been proved to be safe and demonstrated potent cytotoxicity against AML blasts from AML patients in preclinical and preliminary clinical studies. Allo- DNT cells will be collected from healthy donors (NO MHC match needed) and injected into patients. The drug for this study is an off-the-shelf product. Patients DO NOT need to wait for the cell manufacturing.
Eligibility Criteria
You may qualify if:
- Voluntarily sign an ICF and expect to complete the study procedures for follow-up examinations and treatment.
- Aged 18 to 70 years (including cut-offs), regardless of gender.
- Accordance with the diagnostic criteria of AML in the 2016 WHO staging and meeting the diagnostic criteria of relapsed and refractory in the Chinese Guidelines for the Treatment of Relapsed/Refractory Acute Myeloid Leukemia (2017 edition).
- Diagnostic criteria for Relapsed AML: reappearance of leukemic cells in peripheral blood or \>5% primitive/naive cells in bone marrow after CR (except for other causes such as bone marrow regeneration after consolidation chemotherapy) or extra-marrow infiltration of leukemic cells.
- Diagnostic criteria for refractory AML: primary refractory disease that has not achieved complete remission after two courses of induction chemotherapy with a standard regimen (containing cytarabine and an anthracycline or anthraquinone).
- The patient has recovered from the toxicity of the prior treatment, i.e., less than a grade 2 CTCAE toxicity rating (unless the abnormality is tumor-related).
- ECOG score 0 to 1.
- Appropriate organ function, and accordance with the following criteria within 7 days prior to lymphodepleting chemotherapy.
- Glutathione aminotransferase (AST) ≤ 3 times the upper limit of normal (ULN)
- Glutamic aminotransferase (ALT) ≤ 3 times ULN.
- Total bilirubin ≤ 1.5 times ULN, unless the patient has documented Gilbert syndrome. Patients with Gilbert-Meulengracht syndrome with total bilirubin ≤ 3.0 times ULN and direct bilirubin ≤ 1.5 times ULN may be included.
- Serum creatinine ≤ 1.5 times ULN or a creatinine clearance ≥ 60 ml/min.
- Hemoglobin ≥ 60 g/L or hemoglobin maintained at that level following transfusion.
- Absolute neutrophil count (ANC) ≥ 1.0 x 10\^9/L.
- A platelet count ≥ 30 x 10\^9/L or a platelet count maintained at that level following a platelet transfusion
- +5 more criteria
You may not qualify if:
- A diagnosis of acute promyelocytic leukemia.
- Patients with extramedullary infiltration of leukemia.
- Evidence or history of central nervous system invasion or cranial neuropathy.
- Patients with positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and peripheral blood hepatitis B virus (HBV) DNA titration assay not within the normal reference range, positive hepatitis C virus (HCV) antibody and peripheral blood HCV RNA ,positive for human immunodeficiency virus (HIV), or positive for cytomegalovirus (CMV) DNA, or positive syphilis test.
- Persons with hypersensitivity to excipients of RC1012 injection (e.g., human albumin) or other drugs recommended in the study protocol (e.g., lymphodepleting treatment, Tocilizumab).
- Serious cardiac disease, including but not limited to severe arrhythmia, unstable angina, massive heart attack, New York Heart Association class III or IV cardiac insufficiency, refractory hypertension.
- Persons who have previously received an organ transplant or are preparing to receive an organ transplant (except for hematopoietic stem cell transplantation)
- Persons with acute and chronic graft-vs-host disease (GVHD)
- Those who have received a hematopoietic stem cell transplant within 2 months prior to screening tests.
- Active neurological autoimmune or inflammatory diseases (e.g. Guillain-Barre Syndrome (GBS), Amyotrophic lateral sclerosis (ALS)) and clinically significant active cerebrovascular disease (e.g. cerebral oedema, Posterior Reversible Encephalopathy Syndrome (PRES)).
- Patients with a life expectancy of less than 3 months
- Patients have been involved in other clinical studies within 3 months prior to screening.
- Patients, in the judgement of the investigator and/or clinical criteria, are contraindicated to any study procedure or have other medical conditions that may place them at unacceptable risk.
