Natural Killer(NK) Cell Therapy in r/r AML

Registration Number
NCT05665114
Lead Sponsor
Zhejiang University
Brief Summary

This is an open-label, Phase I study of QN-030a (allogeneic NK cell therapy) in relapse/refractory Acute Myeloid Leukemia (AML).

This clinical study is to evaluate the safety, tolerability and preliminary efficacy of QN-030a in patients with r/r AML, where a "3+3" enrollment schema will be utilized at dose escalation stage. Up to 18 patients will be enrolled.

Primary Outcome Measures
NameTimeMethod
Incidence of subjects with Dose Limiting Toxicities within each dose level cohort28 Days from first dose of QN-030a
Determine the Maximum tolerated dose (MTD) and RP2D28 Days from first dose of QN-030a
Incidence and severity of Treatment-Emergent Adverse Events [Safety and Tolerability]Up to approximately 2 years after last dose of QN-030a
Incidence of dose adjustment or discontinuation due to NK cell toxicitiesUp to approximately 2 years after last dose of QN-030a
Secondary Outcome Measures
NameTimeMethod
Overall Response Rate(ORR) of QN-030a in r/r AMLUp to approximately 2 years after last dose of QN-030a

Proportion of subjects who achieve a CR, CRi, CRMRD-, MLFS, or PR, as determined by investigator.

Time to Response (TTR) of QN-030a in r/r AMLUp to approximately 2 years after last dose of QN-030a
Determination of the pharmacokinetics (PK) of QN-030a cells in peripheral bloodUp to approximately 2 years after last dose of QN-030a

The PK of QN-030a in peripheral blood will be reported as the relative percentage of product (QN-030a) DNA versus patient DNA (% chimerism) measured from blood samples at the specified time points

Relapse-free survival (RFS) of QN-030a in r/r AMLUp to approximately 2 years after last dose of QN-030a
Overall Survival (OS) of QN-030a in r/r AMLUp to approximately 2 years after last dose of QN-030a
Event-free survival (EFS) of QN-030a in r/r AMLUp to approximately 2 years after last dose of QN-030a
Evaluate the immunogenicity features of QN-030aUp to approximately 2 years after last dose of QN-030a

The Donor specific antibody (DSA) and T cell receptor (TCR) will be measured.
