Fatal treatment-emergent CNS hemorrhage not in the setting of progressive disease occurred in 2% of patients in the VYXEOS arm and 0.7% in the control arm (7+3).
Other adverse reactions that occurred in ≥10% of patients in the VYXEOS arm included dizziness, fungal infection, hypertension, hypoxia, upper respiratory infections (excluding fungal), chest pain, pyrexia, catheter/device/injection site reaction, delirium, pleural effusion, anxiety, pruritus, sepsis (excluding fungal), hemorrhoids, petechiae, renal insufficiency, transfusion reactions, and visual impairment (except bleeding).
The safety population included all patients in the VYXEOS cohort and 151 patients from the 7+3 cohort (5 patients withdrew consent before the receipt of treatment).1
aAdverse reactions were graded using National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0.
Time to recovery of absolute neutrophil count and platelets may be prolonged with VYXEOS and require additional monitoring2
- Incidences of Grade 3 thrombocytopeniab were prolonged in the absence of active leukemia in 28% (16/58) of patients in the VYXEOS arm and 12% (4/34) of patients in the 7+3 arm during Induction 1 and in 25% (12/48) of patients in the VYXEOS arm and 16% (5/32) of patients in the 5+2 arm during Consolidation 1
- Incidences of Grade 4 neutropeniab were prolonged in the absence of active leukemia in 17% (10/58) of patients in the VYXEOS arm and 3% (1/34) of patients in the 7+3 arm during Induction 1 and in 10% (5/48) of patients in the VYXEOS arm and 3% (1/32) of patients in the 5+2 arm during Consolidation 1
- bPlatelets <50 Gi/L or neutrophils <0.5 Gi/L lasting past cycle Day 42 in the absence of active leukemia.2
Mortality Rates
VYXEOS was associated with lower 30- and 60-day mortality rates compared with 7+32
30- and 60-day overall all-cause mortality in patients with sAML aged 60-75 years (safety population)
- 9 patients each in the VYXEOS arm (6%) and control arm (6%) had a fatal adverse reaction on treatment or within 30 days of treatment that was not in the setting of progressive disease
- 8 patients in the control arm (5%) died within 30 days of treatment due to progressive leukemia
- Fatal adverse reactions in the VYXEOS arm included infection, CNS hemorrhage, and respiratory failure
POSt hoc analysis
Lower cardiotoxicity rates with VYXEOS vs 7+33,4
A post hoc analysis was conducted to assess the impact of VYXEOS vs 7+3 on cardiac impairment in a subset of patients from the Phase 3 study.
Percentage of patients with clinically
significantc,d
change in LVEF or GLS3
Patients from the Phase 3 study (VYXEOS [n=57]; 7+3 [n=45]) with normal baseline LVEF and at least one postbaseline echocardiogram measure were evaluated. Patients with prior cumulative anthracycline exposure of
>368 mg/m2 daunorubicin (or equivalent) were excluded from the study.3
Cardiac function was assessed at3:
- Baseline (treatment initiation)
- Follow-up 1: 30-45 days from last induction or prior to consolidation or salvage therapy, and/or
- Follow-up 2: Day 150 or 45 days from last treatment (whichever was later)
Median baseline LVEFc and GLSd in the VYXEOS and 7+3 arms were3:
- LVEF: VYXEOS, 63.3; 7+3, 62.0
- GLS: VYXEOS, -21.3; 7+3, -21.1
Limitations of subanalysis3
The limitations of this analysis include its post hoc design, the restricted patient population, and limited follow-up time points. No conclusions should be drawn. Analysis was not powered to determine statistical significance.
VYXEOS treatment is not recommended in patients with LVEF that is less than normal. Discontinue VYXEOS in patients with impaired cardiac function unless the benefit of initiating or continuing treatment outweighs the risk.2
- CNS=central nervous system; GLS=global longitudinal strain; LVEF=left ventricular ejection fraction.
- cLVEF normal baseline defined as >53% and clinically significant change defined as >10% absolute decrease from baseline and LVEF <53%.3
- dGLS normal baseline defined as ≥18% and clinically significant change defined as >12% relative decrease from baseline and GLS <18%.3
Outpatient Strategies
Some patients may be appropriate for outpatient administration of VYXEOS, giving you more options when planning their treatment. Read how some institutions are approaching outpatient use of VYXEOS.

About sAML
Secondary AML is a broad category of high-risk AML that includes multiple subtypes of leukemias with different characteristics but similar poor prognosis and significant challenge to reach a cure.5,6 Learn more about which patients may be appropriate for intensive chemotherapy with VYXEOS.
