Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of selinexor and HAAG +/- HMA in relapsed/refractory acute leukemia (AML) patients.

Description:

This protocol corresponds to a single-center, open-label, single-arm, exploratory study designed to determine the efficacy and safety of the combination of selinexor with HAAG +/- HMA in patients with relapsed or refractory AML. The patients who respond to this combination treatment will undergo allogeneic hematopoietic stem cell transplantation and post-transplantation maintenance treatment according to patient's wishes.

Each cycle of treatment will compromise 2 weeks of selinexor treatment, and at least two weeks off treatment. The new cycle will not start if there is an ongoing grade 3 or higher non-hematologic toxicity or persistent grade 3 neutropenia in patients achieving CR.

Study design allows 20 patients. Treatment will consist of selinexor 60 mg/day orally on d1,4,8,11, HHT 1 mg/day intravenously on days 3 to 9, cytarabine 10 mg/m2 q12h, intravenously on days 3 to 9, aclacinomycin 10 mg/day intravenously on days 3 to 6, G-CSF 50-600 mcg/m2/day intravenously from days 2 to start, this dosage will be adjusted according to the hemogram, DAC 20 mg/m2/day intravenously on days 1 to 5. Whether to add hypomethylating agents was decided by the investigator according to the patient's disease degree and tolerance status. If patients had previously been exposed to decitabine, azacitidine will added this regimen, AZA 20 mg/m2/day subcutaneously on days 1 to 7.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With CR/CRi	Number of Participants With CR/CRi; CR: Absolute Neutrophil count (ANC) >1.0x10^9/L, Platelet count >100x10^9/L, Bone marrow blasts <5%, no Auer rods, no evidence of extramedullary disease.; CRi: Same as CR, but ANC may be <1.0x10^9/L and/or Platelet count <100x10^9/L	End of cycle 1 and 2 (each cycle is 28 days)
Secondary	Number of Participants With ORR	ORR =CR+CRi+PR+MLFS; PR: Absolute Neutrophil count (ANC) >1.0x10^9/L, Platelet count >100x10^9/L, at least a 50% decrease in the percentage of marrow aspirate blasts to 5-25%, or marrow blasts <5% with persistent Auer rods.; MLFS: Bone marrow blasts <5%, no Auer rods, no evidence of extramedullary disease	End of cycle 1 and 2 (each cycle is 28 days)
Secondary	Percentage of Patients Transplanted After Induction Therapy (Stem Cell Transplantation)	Rate of ASCT: Percentage of patients being transplanted after induction therapy (stem cell transplantation)	1-2 induction cycles (4 - 8 weeks)
Secondary	Progression-Free Survival	Progression-free survival (PFS): was calculated from the time of informed consent to the date of recurrence or death, whichever occurred first. Patients were censored at the date of the last follow-up visit if they were alive without relapse.; Disease progression was defined as presence of >50% increase in bone marrow blasts to a level of at least 50% and/or a doubling of the percentage of peripheral blood blasts to a level of at least 50%.	Time from registration to event, max 2 years
Secondary	Overall Survival	Overall survival (OS) was calculated from the date of informed consent to the date of death. Patients still alive at the end of follow-up were censored at the last date of follow-up.	Time from registration to event, max 2 years
Secondary	Number of adverse events	Adverse events are evaluated with CTCAE V5.0	End of cycle 1 and 2 (each cycle is 28 days)
