Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to document and characterized: Phase I: the safety of the NKR-2 treatment administration in r/r AML/MDS patients after a non-myeloablative preconditioning. Phase II: the clinical activity of the NKR-2 treatment administration in r/r AML/MDS patients after a non-myeloablative preconditionning;Secondary Objective: The secondary objectives are to document and characterize: • The NKR-2 peripheral blood kinetics post-administration, • Indicators of clinical activity, • Additional indicators of safety. ;Primary end point(s): Phase I: The occurrence of DLTs during the study treatment. Phase II: The objective response rate (ORR) post the first KKR-2 administration;Timepoint(s) of evaluation of this end point: Phase I: During the administration phase, up to administration phase concluding visit. Phase II: at W3, W7 (only if consolidation cycle), W11, and only for patients authorized for the consolidation cycle at M6, M9, M12, M18 and M24 post the first NKR-2 administration. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): PHASE I A - NKR-2 cell kinetics and dynamics endpoints 1) The evaluation of circulating NKR-2 in the peripheral blood and its kinetics post-injection. B - Safety endpoints 2) The occurrence of AEs and SAEs and any toxicity linked to study participation until the end of the treatment follow-up (at M24). C - Clinical activity endpoints 3) The overall survival (OS), relapse-free survival (RFS) and event-free survival (EFS) from study enrollment. 4) The objective clinical response rate (ORR) and objective clinical benefit rate (OCBR) post the first NKR-2 administration. 5) The duration of response for patients with objective clinical response 6) The ORR and duration of second response among patients retreated with NKR-2. 7) The cumulative incidence of relapse (CIR) and cumulative incidence of death (CID). 8) The non-relapse mortality (NMR) rate. 9) For AML patients: the incidence of CR, CRMRD-, CRi, MLFS, PR, or SD post NKR-2 administrations until the end of the treatment follow-up (at M24). 10) For MDS patients: the incidence of CR, PR, marrow CR, cytogenic response, hematologic improvement or SD post NKR-2 administrations until the end of the treatment follow-up (at M24). Phase II: A - Safety endpoints 1) The occurrence of DLTs during the administration phase, 2) The occurrence of AEs and SAEs and any toxicity linked to study participation until the end of the treatment follow-up (at M24). B - Clinical activity endpoints 3) The overall survival (OS), relapse-free survival (RFS) and event-free survival (EFS) from study enrollment. 4) The objective clinical benefit rate (OCBR) post the first NKR-2 administration. 5) The duration of response for patients with objective clinical response. 6) The ORR and duration of second response among patients retreated with NKR-2. 7) The cumulative incidence of relapse (CIR) and cumulative incidence of death (CID). 8) The non-relapse mortality (NMR) rate. 9) For AML patients: the incidence of CR, CRMRD-, CR | — |
