Outcomes

Primary Outcome Measures

Response Rate (RR)
The response rate was determined as the sum of complete response calculated by adding the total complete response (CR) and complete response with incomplete count recovery (CRi). The outcome is reported as the total number without dispersion. CR = less than 5% blasts; no blasts with auer rods; and no persistence of extramedullary disease, with blood count recovery to platelets ≥ 100,000/uL and ANC > 1000/uL, with transfusion independence. CRi = all the parameters for CR, but platelets < 100,000/uL and/or ANC ≤ 1000/uL.

Secondary Outcome Measures

Complete Response With Incomplete Count Recovery (CRi)
Complete response (CR) with incomplete count recovery (CRi) was determined as the number of participants who achieved CRi after induction therapy. The outcome is reported as the total number or participants without dispersion. CR = less than 5% blasts; no blasts with auer rods; and no persistence of extramedullary disease, with blood count recovery to platelets ≥ 100,000/uL and ANC > 1000/uL, with transfusion independence. CRi = all the parameters for CR, but platelets < 100,000/uL and/or ANC ≤ 1000/uL.
Complete Response (CR)
Complete response (CR) was determined the number of participants who achieved CR by Day 42 after induction treatment. The outcome is reported as the total number of participants without dispersion. • CR = less than 5% blasts; no blasts with auer rods; and no persistence of extramedullary disease, with blood count recovery to platelets ≥ 100,000/uL and ANC > 1000/uL, with transfusion independence.
Duration of Remission (DOR) Following Induction With CPX-351
Duration of remission (DOR) was assessed as the length of time from documented complete response (CR) or complete response with incomplete count recovery (CRi) until documented lost of response, relapse, or death. The outcome is reported as the median with full range. CR = less than 5% blasts; no blasts with auer rods; and no persistence of extramedullary disease, with blood count recovery to platelets ≥ 100,000/uL and ANC > 1000/uL, with transfusion independence. CRi = all the parameters for CR, but platelets < 100,000/uL and/or ANC ≤ 1000/uL. For patients remaining alive, duration of remission (DOR) is reported as the length of time from documented complete response (CR) or complete response with incomplete count recovery (CRi) until the most recent assessment.
Overall Survival (OS)
Overall survival (OS) was assessed as the number of participants remaining alive 12 months, starting from date of entry into trial. The outcome is reported as the number of participants (without dispersion).
Early Induction Mortality (Day 30 After 1st Induction)
Early induction mortality was assessed as the number of participants who died within 30 days of completing the 1st cycle of CPX-351 (1st induction). The outcome is reported as the number of participants without dispersion.
Mortality at Day 60 After 1st Induction
Mortality at Day 60 after 1st induction was assessed as the number of participants who died within 60 days of completing the 1st cycle of CPX-351 (1st induction). The outcome is reported as the number of participants without dispersion.
Participants Experiencing of Serious Adverse Events
Serious adverse events per participant were assessed as serious adverse events per 21CFR§312.32 that were Grade 3 or greater, and independent of relationship to CPX-351. The outcome is reported as the number of participants that experienced any defined SAE, a number without dispersion.
Serious Adverse Events
Serious adverse events were assessed as serious adverse events per 21CFR§312.32 that were Grade 3 or greater, and independent of relationship to CPX-351. The outcome is reported as the total number of the defined SAEs, a number without dispersion.

5. Study Description

Brief Summary
This phase 2 clinical trial studies how well CPX-351 (liposomal cytarabine-daunorubicin) works in treating patients with relapsed or refractory acute myeloid leukemia or myelodysplastic syndrome. Drugs used in chemotherapy, such as CPX-351, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
Detailed Description
PRIMARY OBJECTIVES: Determine efficacy of CPX-351 by measuring the response rate as the sum of complete response (CR) and complete remission with incomplete count recovery (CRi) in older patients (age 60 and older) with: higher risk of myelodysplastic syndrome (MDS) who are refractory/relapsed after prior hypomethylating (HMA) therapy; subjects greater than 75 years old with higher risk MDS who are HMA relapsed/refractory who have progressed to acute myeloid leukemia (AML)); AML with refractory/relapsed disease after prior HMA therapy for AML. SECONDARY OBJECTIVES: Determine the safety of CPX-351, as the frequency of Grade 3 to 5 SAEs Determine the duration of remission (DOR) following induction therapy with CPX-351. Determine overall survival (OS) at 12 months. Determine the early induction mortality (at 30 and 60 days) following CPX-351 following induction therapy. OUTLINE: Patients receive liposomal cytarabine-daunorubicin CPX-351 intravenously (IV) at a dose of 65 units/m2/day over 90 minutes on days 1, 3, and 5 of each induction cycle. 1st INDUCTION: Patients receive liposomal cytarabine-daunorubicin CPX-351 IV at a dose of 65 units/m2/day over 90 minutes on days 1, 3, and 5. Patients achieving a complete remission (CR) or a CR with incomplete blood count recovery (CRi) at day 14 proceed to consolidation therapy 2nd INDUCTION: Patients with reduced blast count not achieving a morphological leukemia free state (< 5% blasts) receive the 2nd course of induction therapy. Patients receive liposomal cytarabine-daunorubicin CPX-351 IV a dose of 65 units/m2/day over 90 minutes on days 1 and 3. Patients achieving a complete remission (CR) or a CR with incomplete blood count recovery (CRi) after the 2nd course of induction therapy proceed to consolidation therapy. CONSOLIDATION: Beginning on day 28, patients receive liposomal cytarabine-daunorubicin CPX-351 IV a dose of 65 units/m2/day over 90 minutes on days 1 and 3. After completion of study treatment, patients are followed up for up to 1 year.
