AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with CD123-positive acute myeloid leukemia (AML) or blastic plasmacytoid dendritic cell neoplasm (BPDCN) that came back or did not respond to treatment.
- Age
- 18 to 75 years
- Sex
- All sexes
- Disease stage
- Relapsed or refractory AML or BPDCN with CD123 on the tumor cells. For AML: leukemia came back after remission, or did not respond to two courses of standard treatment. For BPDCN: no response to, or cannot tolerate, the guideline salvage treatment, and the disease is still present or has returned.
- Earlier treatment
- AML: no response to two courses of standard treatment, or relapse after remission and consolidation therapy. BPDCN: no response to guideline salvage treatment. No anti-tumor treatment within 14 days or 5 half-lives (whichever is shorter), unless the disease progressed after treatment.
- Biomarker or test result
- CD123 must be found on tumor cells by flow cytometry.
Main reasons for not taking part
- Active cancer spread to the central nervous system
- Stroke or epileptic seizure in the last 6 months
- Active or uncontrolled infection needing systemic treatment in the last week
- Serious heart disease, such as NYHA class III or IV heart failure or a heart attack in the last 6 months
- Pregnant or breastfeeding, or planning a child within 1 year after the infusion

Clinical Study of CD123 Targeting Chimeric Antigen Receptor NK Cells (CAR-NK) in the Treatment of Relapse/Refractory Acute Myeloid Leukemia (AML)or Blastic Plasmacytoid Dendritic Cell Neoplasm(BPDCN)
This is a clincal trial initiated by investigator to evaluate the safety and efficacy of anti-CD123 CAR-NK in the treatment of patients with relapsed/refractory acute myeloid leukemia or blastic plasma cell like dendritic cell tumors.
Inclusion: Patients of any gender, aged between 18 and 75 years (inclusive); Positive expression of CD123 on tumor cells detected by flow cytometry; Patients with a confirmed diagnosis of CD123-positive relapsed/refractory AML or BPDCN:; (1) For AML patients：; Relapsed refers to the reappearance of leukemic cells in peripheral blood after complete remission (CR), or ≥5% blasts in bone marrow (excluding other reasons such as bone marrow regeneration after consolidation chemotherapy), or the presence of leukemic cell infiltration outside the marrow; Refractory refers to patients who have not responded to two courses of standard treatment; patients who have relapsed within 12 months after CR and consolidation/intensification therapy; patients who have relapsed after 12 months but have not responded to conventional chemotherapy; patients with two or more relapses; patients with persistent extramedullary leukemia; (2) For BPDCN patients: Patients who have not responded to or cannot tolerate the recommended salvage treatment according to guidelines, and have persistent or recurrent disease in any of the following: peripheral blood, bone marrow, lymph nodes, spleen, skin lesions, or other sites; Expected survival time of more than 12 weeks; ECOG score of 0-2 (Appendix 2); No severe mental disorders; Basic normal function of important organs:; Blood routine: white blood cells >1.0×109/L, neutrophils >0.5×109/L, lymphocytes >0.5×109/L, platelets >50×109/L; Cardiac function: echocardiography indicates a left ventricular ejection fraction ≥50%, and no significant abnormalities on electrocardiogram; Renal function: serum creatinine ≤2.0×ULN; Liver function: ALT and AST ≤3.0×ULN (for patients with liver invasion; 5.0×ULN); Total bilirubin ≤2.0×ULN (for patients with Gilbert's syndrome ≤3.0×ULN); Blood oxygen saturation >92%. 8. The patient or their legal guardian agrees to participate in this clinical trial and signs the ICF, indicating their understanding of the purpose and procedures of the clinical trial and willingness to participate in the study.
Exclusion: Receipt of anti-tumor therapies prior to screening, including chemotherapy, targeted therapy, or other experimental drug treatments within 14 days or at least 5 half-lives (whichever is shorter), except for those who have confirmed disease progression after treatment; Occurrence of cerebrovascular accident or epileptic seizure within 6 months prior to screening; Presence of active or uncontrolled infection requiring systemic treatment within 1 week prior to screening; Presence of any of the following cardiac diseases:; Congestive heart failure at New York Heart Association (NYHA) class III or IV; Myocardial infarction or coronary artery bypass grafting (CABG) within 6 months prior to enrollment; Clinically significant ventricular arrhythmia, or history of unexplained syncope (excluding cases caused by vasovagal or dehydration); History of severe non-ischemic cardiomyopathy; Receipt of live attenuated vaccines within 4 weeks prior to screening; Pregnant or breastfeeding women, as well as male or female subjects who plan to have children within 1 year after receiving CAR-NK cell infusion; Combination with active autoimmune diseases requiring long-term immunosuppressive therapy; Presence of other malignancies, except for adequately treated carcinoma in situ of the cervix, basal cell or squamous cell carcinoma of the skin, localized prostate cancer after radical surgery, and ductal carcinoma in situ after radical surgery; Other conditions that the investigator deems unsuitable for participation in the study; Presence of active central nervous system invasion during screening.
