Study Investigating the Efficacy and Safety of the Addition of Oral-azacitidine to Salvage Treatment by Gilteritinib in Subjects ≥18 Years of Age With Relapsed/Refractory FLT3-mutated Acute Myeloid Leukemia
Lead Sponsor:
French Innovative Leukemia Organisation

Conditions:
AML, Adult
Refractory AML
Eligibility:
All Genders
18+ years
Phase:
PHASE2
Brief Summary
Approximately 30% of adult AML subjects are refractory to induction therapy. Furthermore, of those who achieve CR, approximately 75% will relapse. FLT3-mutated AML comprise an especially poor prognosi...
Detailed Description
AML is characterized by the clonal expansion of myeloid blasts in the BM, peripheral blood and extramedullary tissues which disrupts normal hematopoiesis. It is a heterogeneous disease, encompassing a...
Eligibility Criteria
Inclusion
- Inclusion Criteria:
- Confirmed diagnosis of acute myeloid leukemia (AML) according to world health organization (WHO) 2016 classification
- Presence of FLT3-mutation(s) at inclusion: in case of FLT3-ITD, the ITD/wt ratio must be \> 0.05 ; in case of FLT3-TKD, the mutation must be at D835 or I836 position with a VAF \> 5% by NGS.
- Subjects must be primary refractory or relapsed (R/R) to 1st line intensive chemotherapy (ICT) for AML. Hydroxyurea is allowed for the control of peripheral leukemic blasts in patients with leukocytosis.
- 3a. Primary refractory is defined as no CR or CRi after at least one course of ICT (including "7+3", gemtuzumab ozogamycin (GO)-based and CPX-351, including or not midostaurine) or two courses (maximum 4) of AZA and venetoclax 3b. Relapse after 1st line ICT for AML is defined as the first hematologic relapse with bone marrow blasts \>5% after one line of treatment for AML that includes at least one course of ICT (one line of treatment for AML can include induction, re-induction, consolidation, allogeneic HSCT and maintenance) 3c. Relapse after 1st line non intensive chemotherapy for AML is defined as the first hematologic relapse with bone marrow blasts \>5% after or during treatment by AZA venetoclax regardless of number of cycles 4. 1st line intensive treatment may or may not include previous treatment by tyrosine kinase inhibitor (TKI) except gilteritinib.

Patient must be affiliated to the french social security (health insurance) 13. Signed written informed consent for the study 14. Female subject must agree not to breastfeed starting at screening and throughout the study period, and for 60 days after the final study drug administration.
- 15\. Female subject must not donate ova starting at screening and throughout the study period, and for 180 days after the final study drug administration.
- 16\. A male subject with female partner(s) of childbearing potential must agree to use contraception starting at screening and continue throughout the study period, for at least 120 days after the final study drug administration.
- 17\. Male subject must not donate sperm starting at screening and throughout the study period and for 120 days after the final study drug administration.
- Exclusion criteria
- 1\. Subjects with any of the following current or previous diagnoses:
- 1a. AML secondary to prior myeloproliferative syndrome (MPN)
- 1b. Acute promyelocytic leukemia (APL) and core binding factor (CBF) AML
- 1c. DNA fragility or bone marrow (BM) failure syndromes
- 1d. Blastic plasmacytoid dendritic cell neoplasm
- 1e. Acute lymphoblastic leukemia including ambiguous lineage 2. Patients ≥ 3rd line of treatment, HSCT being not considered as a line of treatment 3. Patients previously treated by AZA as single agent for AML are not allowed 4. Subjects that have previously been treated by gilteritinib 5. Subjects that have previously been treated by oral azacitidine 6. Clinically active central nervous system (CNS) leukemia 7. Subjects who have received more than 1 prior allogeneic HSCT 8. Subjects who have relapsed within 100 days after allogeneic HSCT 9. Presence of Grade 2 or above graft-versus-host disease (GVHD), including acute, chronic, or overlap; or escalation of therapy for GVHD within 14 days prior to randomization 10. Subject requires treatment with concomitant drugs that are strong inducers of cytochrome P450 (CYP)3A (Annexe 7) 11. Subject requires treatment with concomitant drugs that are strong inhibitors or inducers of P-gp with the exception of drugs that are considered absolutely essential for the care of the subject (Annexe 7) 12.
