Venetoclax and Azacitidine for the Management of Molecular Relapse/Progression in Adult NPM1-mutated Acute Myeloid Leukemia

NCT04867928 | Unknown Phase 2

• 1 other identifier: AML2521
• Study Type: interventional
• Target: 35
• Locations: 1 country
• Sites: 1

Brief Summary

This is a phase 2, non-randomized, interventional, open-label, multicenter trial evaluating the efficacy of VEN-AZA as a bridge-to-transplant therapy in chemotherapy-treated adult NPM1mut AML patients who experience molecular relapse or progression during treatment or follow-up. Subjects will receive cycles of venetoclax plus azacitidine. After each cycle, MRD will be evaluated and at any time of MRD-negativity, AlloSCT will be performed.

Conditions

Acute Myeloid Leukemia; Acute Myeloid Leukemia, in Relapse; NPM1 Mutation

Outcome Measures

Primary Outcomes (1)

• Treatment efficacy in terms of relapse rate

  Evaluation of treatment efficacy in terms of percentage of patients who do not experience overt relapse at 6 months or within stem cell transplant.

  at 6 months

Study Arms (1)

Venetoclax+azacitidine

EXPERIMENTAL

subjects will receive treatment until alloSCT

Drug: Venetoclax+azacitidine

Interventions

Venetoclax+azacitidine DRUG

subjects will receive venetoclax 400 mg orally QD on Days 1 - 28 plus azacitidine 75 mg/m2 SC or IV daily for 7 days. Cycle Length - 28 Days. . Subjects will continue treatment until subsequent alloSCT.

Venetoclax+azacitidine

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject must be ≥ 18 years of age
• Subject must have received previous diagnosis of NPM1mut AML with or without concomitant FLT3-TKD or FLT3-ITD
• At screening, subject must have confirmed NPM1 type A, B, or D mutant transcripts
• Subject must be eligible for alloSCT, according to transplant center policy
• Subject must have undergone at least two cycles of conventional anthracycline- and cytarabine-based chemotherapy, achieving first CR (CR1)
• Subject must be in morphological CR1 with bone marrow detectable minimal residual disease (MRD) positivity, defined as qRT-PCR NPM1 transcript ≥ 0.01/100 ABL1 copies and confirmed in two consecutive determinations performed at 2 to 4 weeks' distance
• Molecular progression is defined in patients with molecular persistence at low copy number as an increase of MRD copy number ≥ 1 log10 between 2 positive samples.
• Molecular relapse is defined in patients previously tested MRD negative as an increase in MRD copy number ≥ 1 log10 between 2 positive samples
• Subject must have a projected life expectancy of at least 12 weeks.
• Subject must have an Eastern Cooperative Oncology Group (ECOG) Performance status \< 2
• Subject must have adequate renal and hepatic function per local laboratory reference range as follows:
• Aspartate transaminase (AST) and alanine transaminase (ALT) \< 3.0X ULN
• Bilirubin ≤1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin)
• Subject must have adequate renal function as demonstrated by a creatinine clearance ≥ 30 mL/min; calculated by the Cockcroft Gault formula or measured by 24 hours' urine collection.
• Female subjects of childbearing potential must have negative results for pregnancy test at screening

You may not qualify if:

• Subject has acute promyelocytic leukemia (APL)
• Subject has known active CNS involvement with AML
• Subject has received previous treatment with venetoclax and/or hypomethylating agents
• Subject has undergone alloSCT for AML
• Subject has more than 5% of bone marrow blast cells at screening bone marrow aspirate
• Subject is known to be positive for HIV
• Evidence of other clinically significant uncontrolled condition(s) including, but not limited to:
• Uncontrolled and/or active systemic infection (viral, bacterial or fungal)
• Chronic hepatitis B virus (HBV) or hepatitis C (HCV) requiring treatment. Note: subjects with serologic evidence of prior vaccination to HBV (i.e. hepatitis B surface (HBs) antigen negative-, anti-HBs antibody positive and anti-hepatitis B core (HBc) antibody negative) or positive anti-HBc antibody from intravenous immunoglobulins (IVIG) may participate.
• Cardiac history of CHF requiring treatment or Ejection Fraction ≤ 50% or chronic stable angina;
• DLCO ≤ 65% or FEV1 ≤ 65%;
• Creatinine clearance \< 30 ml/min
• Subject has a cardiovascular disability status of New York Heart Association Class \> 2
• a. Class 2 is i. defined as cardiac disease in which patients are comfortable at rest but ordinary physical activity ii. results in fatigue, palpitations, dyspnea, or anginal pain
• Patients who are pregnant or breast feeding and adults of reproductive potential not employing an effective method of birth control (women of childbearing potential must have a negative serum pregnancy test within 48 hrs prior to administration of induction therapy). Post-menopausal women must be amenorrhoic for at least 12 months to be considered of non-child bearing potential. Male and female patients must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drugs.
