About this study
Official title: A Clinical Study on the Safety of CLL-1-Targeted In Vivo CAR-T-Cell Immunotherapy for Relapsed/Refractory Acute Myeloid Leukemia
This is a single-center, open-label, single-arm, phase 1 dose-escalation study to evaluate the safety, tolerability, preliminary efficacy, and cellular kinetics of SL1CC Injection, an in vivo CAR-T therapy targeting CLL-1, in patients with relapsed or refractory acute myeloid leukemia (R/R AML; acute promyelocytic leukemia excluded). SL1CC Injection is administered as a single intravenous infusion without lymphodepleting conditioning. Dose escalation follows a traditional 3+3 design with planned dose levels of 1 × 10^9, 3 × 10^9, and 6 × 10^9 transducing units (TU), guided by the occurrence of dose-limiting toxicities (DLTs). Treatment-emergent adverse events and serious adverse events, including cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), hematologic toxicity, organ toxicity, and other immune therapy-related toxicities, will be assessed. Preliminary antitumor activity, assessed by composite complete remission (CR/CRi) and measurable residual disease (MRD) status according to the European LeukemiaNet (ELN) 2022 criteria, and the expansion and persistence of CAR-T cells in peripheral blood will also be evaluated.
Read the detailed description
This is a single-center, single-arm, open-label, phase 1 dose-escalation study of SL1CC Injection in adults with R/R AML. SL1CC is an in vivo CAR-T product in which a lentiviral vector (LVV) encoding a CLL-1-specific chimeric antigen receptor is administered intravenously to transduce the patient's endogenous T cells in situ; no leukapheresis, ex vivo manufacturing, or lymphodepleting conditioning is required. Three dose levels are planned (1 × 10^9, 3 × 10^9, and 6 × 10^9 TU) using a traditional 3+3 escalation design, and dose-limiting toxicity (DLT) is assessed during the first 28 days after a single infusion. Anticipated enrollment is 12 participants (range 9-18, depending on the number of dose levels requiring expansion). The study includes a screening period, a treatment (infusion) period, and a follow-up period of up to 24 months. Safety assessments include adverse events and serious adverse events graded per NCI CTCAE v6.0, with CRS and ICANS graded per the ASTCT consensus criteria; hematologic recovery, infection, organ toxicity, and viral shedding (blood, saliva, and urine; qPCR) are also monitored. Disease response is assessed by bone marrow morphology according to the ELN 2022 criteria (CR, CRi, MLFS, and PR), together with MRD measured by multiparameter flow cytometry. Exploratory cellular kinetics include peripheral blood CAR transgene copies (qPCR), CAR-positive T-cell counts, Cmax, Tmax, and AUC0-28d. Long-term safety monitoring for potential insertional mutagenesis associated with integrating lentiviral vectors is planned in accordance with applicable gene therapy guidance.

SL1CC InjectionDrug
SL1CC Injection is an investigational in vivo CLL-1-targeted CAR T-cell therapy for patients with relapsed or refractory acute myeloid leukemia. Participants will receive SL1CC Injection by intravenous infusion at protocol-specified dose levels. Dose escalation will follow a traditional 3+3 design and will be guided by the occurrence of dose-limiting toxicities (DLTs).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing SL1CC Injection in people with Relapsed/Refractory Acute Myeloid Leukemia (AML) and Acute Myeloid Leukemia (AML), run by Liping Dou at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 16 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 2 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ran Zhang (86-13810373716, lipingruirui@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence and Severity of Adverse Events and Serious Adverse Events (time frame: From SL1CC infusion through 12 months after treatment (primary safety observation period); long-term follow-up continues through 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2026; AzTrials last refreshed its copy on 6 Nov 2026.
