WiNK is a Phase I/IIa trial to evaluate the safety and efficacy of oNKord® in 33 adults with acute myeloid leukemia (AML) who are in morphologic complete remission with residual measurable disease and who are currently not proceeding to allogeneic hematopoietic stem cell transplantation.
Full description
WiNK is a prospective 2-stage, open-label, single arm, multicenter Phase I/IIa trial to evaluate the safety and efficacy of oNKord®, an off-the-shelf, ex vivo-cultured allogeneic NK cell preparation, in 33 adults with acute myeloid leukemia (AML) who are in morphologic complete remission (CR) with residual measurable disease (MRD) and who are currently not proceeding to allogeneic hematopoietic stem cell transplantation (allo-HSCT).
Following informed consent and eligibility procedures, subjects enrolled in the trial will receive a lymphodepleting conditioning regimen consisting of cyclophosphamide and fludarabine (Cy/Flu) followed by up to 3 oNKord® infusions 4 days apart.
Stage A of the trial (dose escalation stage) is designed to assess the safety and tolerability of up to 3 oNKord® infusions, 4 days apart, in 3 cohorts of 3 subjects, and to determine the oNKord® recommended Phase II dose (RP2D) to be used in Stage B.
Stage B of the trial (expansion stage) will evaluate the safety, tolerability and efficacy of oNKord® at the RP2D in 24 subjects.
All subjects treated with oNKord® will be followed up until 12 months after the start of treatment. Eligibility criteria for participation in the trial and follow-up duration are the same for subjects in both Stage A and Stage B.

Inclusion criteria
Male or female subjects ≥ 18 years old
Subjects with a diagnosis of AML and related precursor neoplasms according to the WHO 2016 classification (excluding acute promyelocytic leukemia), including secondary AML after an antecedent hematological disease (e.g. myelodysplastic syndrome) and therapy-related AML
Subjects who have achieved morphologic CR, including CRi and complete clinical remission, with MRD documented at screening, as assessed by centralized MFC, after one or two courses of remission induction chemotherapy and who have completed consolidation chemotherapy or who achieved morphologic CR with documented MRD with hypomethylating agents or other relevant appropriate therapies
Subjects who are currently (at the time of screening) not proceeding to allo-HSCT
Life expectancy ≥ 6 months at screening
Adequate renal and hepatic functions within 14 days of study screening, unless clearly disease related, as indicated by the following laboratory values:
Karnofsky Status ≥ 50%
Seropositivity for EBV
Male subjects with partners who are women of childbearing potential must use an effective contraceptive method during the trial and for a minimum of 6 months after trial treatment, or have undergone successful vasectomy at least 6 months prior to entry into the trial (confirmed by semen analysis).
Female subjects of childbearing potential must have a negative serum pregnancy test at screening and agree to use an effective contraceptive method during the trial and for a minimum of 6 months after trial treatment.
Able to understand and willing to provide written informed consent to participate in the trial
Affiliation to a national health insurance scheme (according to applicable local requirements)
Exclusion criteria
Subjects having received prior allogeneic HSCT
Subjects with acute promyelocytic leukemia
Diagnosis of any previous or concomitant malignancy is an exclusion criterion, except when the subject completed treatment (chemotherapy and/or surgery and/or radiotherapy) with curative intent for this malignancy at least 6 months prior to enrolment
Blast crisis of chronic myeloid leukemia
Concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes, uncontrolled hypertension, active or uncontrolled infection) including abnormal laboratory values, that could compromise compliance with the trial protocol or cause unacceptable safety risks
Known allergy to any of the components of oNKord® (e.g., dimethyl sulfoxide [DMSO]) or to any of the drugs to be administered in the preparative regimen to oNKord® infusion
Contraindication to any of the drugs to be administered in the conditioning regimen or oNKord® infusion. This includes Cy, Flu, and medications associated with prophylaxis of AEs
Cardiac dysfunction as defined by:
Pulmonary dysfunction as defined by oxygen saturation < 90% on room air. Pulmonary function test (PFT) is required only in the case of symptomatic or prior known impairments within 28 days before screening - with pulmonary function < 50% corrected diffusing capacity of the lung for carbon monoxide (DLCO) and forced expiratory volume in 1 second (FEV1)
Major surgery within 4 weeks prior to screening or a major wound that has not fully healed
Vaccination with live, attenuated vaccines within 4 weeks prior to screening
Immunosuppressive drugs for concomitant disease. Subject must be able to be off prednisone or other immunosuppressive medications for at least 3 days prior to the start of Cy/Flu regimen
History of stroke or intracranial hemorrhage within 6 months prior to screening
Active infections (viral, bacterial or fungal) that requires specific therapy. Acute anti-infectious therapy must have been completed within 14 days prior to trial treatment
History of human immunodeficiency virus (HIV) or active infection with hepatitis B virus (HBV) or hepatitis C virus (HCV)
Subjects who are undergoing or will be undergoing chemotherapy (including HMAs), radiation therapy, targeted therapy or immunotherapy that cannot be finished or stopped at least 1 week prior to initiating the Cy/Flu conditioning regimen
Positive pregnancy test or breastfeeding for women of childbearing potential
Use of other investigational drugs/therapies within 3 weeks prior to trial treatment (within 6 weeks in the case of drugs/therapies with long half-life) or participation in a concomitant interventional clinical trial
Any serious concomitant medical condition, medication or therapy which could, in the opinion of the Investigator, compromise participation in the trial
Subjects under legal protection measure (guardianship, trusteeship or safeguard of justice) and/or inability or unwillingness to comply with the requirements and procedures of this trial
