CPX-351 as a Novel Approach for the Treatment of Older Patients With AML and MDS

Prior treatment

• Prior 7+3 remission induction chemotherapy for MDS or AML
• More than 2 lines of prior non-intensive therapy.
• Acute myocardial infarction in the previous 12 weeks (from the start of treatment).
• No major surgery within 2 weeks prior to study enrollment.
• Male and female participants who are fertile who do not agree to use an effective barrier methods of birth control (i.e. abstinence) to avoid pregnancy while receiving study treatment and for 30 days after last dose of study treatment. Non-childbearing is defined as \> 1 year postmenopausal or surgically sterilized.

Other illness

• Active signs or symptoms of central nervous system (CNS) involvement by malignancy (lumbar puncture \[LP\] not required).
• New York Heart Association (NYHA) class III or IV heart disease, active ischemia or any other uncontrolled cardiac condition such as angina pectoris, clinically significant cardiac arrhythmia on rhythm control strategy or on pacemaker, uncontrolled hypertension (blood pressure \> 160 systolic and \> 110 diastolic not responsive to antihypertensive medication)
• Any active malignancy (unrelated, non-hematological malignancy) diagnosed within the past 6 months of starting the study drug (other than curatively treated carcinoma-in-situ of the cervix or non-melanoma skin cancer).
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to CPX-351.
• Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• Known history of HIV or active hepatitis B or C.

Lab values

• Any serious medical condition, laboratory abnormality, or psychiatric illness that, in the view of the treating physician, would place the participant at an unacceptable risk if he or she were to participate in the study or would prevent that person from giving informed consent.

Other

• Pregnant or breast feeding
• Acute promyelocytic leukemia (APL)

• Primary refractory or relapsed AML (defined by 2016 World Health Organization \[WHO\] criteria) patients who are not suitable for or not willing to receive intensive chemotherapy as evaluated by the treating physician. Primary refractory disease is defined as:
  • Failure to achieve a CR, CRi, or mLFS (defined as \<5% Bone Marrow (BM) blasts) after receiving 1 or 2 cycles of remission induction chemotherapy.
  • Failure to achieve a CR, CRi, or MLFS (defined as \<5% BM blasts) after receiving 4 cycles of non-intensive chemotherapy or whose disease progressed at any time point during the treatment.
• Participants with MDS (according to 2016 WHO criteria) who did not respond to treatment with azacitidine, decitabine, or combination of HMA with another drug or lost their response to initial therapy with HMA.
• Eastern Cooperative Oncology Group (ECOG) performance status \<=2
• Adequate hepatic (serum total bilirubin \< 1.5 x ULN, Serum glutamic pyruvic transaminase (SGPT) and/or serum glutamate oxaloacetate transaminase (SGOT) \<2.5 x ULN) and renal function (creatinine \< 1.5mg/dL).
• Participants must be willing and able to review, understand, and provide written consent before starting therapy.
