Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: CPX-351 and Glasdegib In Induction, subjects receive 44mg/m2/100mg/m2 IV on days 1, 3 and 5 and Glasdegib 100mg PO daily on days 6 to 28. If re-induction is needed: Subjects receive 44mg/m2/100mg/m2 IV on days 1 and 3 and Glasdegib 100mg PO daily on days 4 to 28. In consolidation: Subjects receive 29mg/m2/65mg/m2 IV on days 1 and 3 and Glasdegib 100mg PO daily on days 4 to 28. If maintenance is required, Subjects receive Glasdegib 100mg PO daily for up to one year |

Outcome Measures
Primary Outcome Measures
- Percentage of Participants with Event-Free Survival at 6 months [6 months]
This is defined as the percentage of subjects with event-free survival (EFS) at 6 months. EFS is defined as the number of months where patients are in a remission state.
Secondary Outcome Measures
- Percentage of Grade 3-5 Adverse Events [From the start date of treatment until 4 weeks after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 1 year.]
To evaluate the tolerability of administering CPX-351 in combination with glasdegib in patients with newly diagnosed with Acute Myeloid Leukemia (AML) with Myelodysplastic Syndrome (MDS) related changes or treatment-related AML from the start of treatment, duration of treatment and up to 4 weeks after completion of study treatment. Toxicity and adverse events are based on the CTCAE (NCI Common Terminology Criteria for Adverse Events) Version 5.0.
- Overall Response Rate [From the start date of treatment until first date of CR/CRi or an average of 1 year.]
To assess the overall response rate to the combination of CPX-351 and glasdegib. The overall response rate (ORR) is defined as the rate of complete remissions (CR) and complete remission with incomplete count recovery (CRi). ORR = CR + CRi
- Durability of Response [From the start date of treatment until first date of CR/CRi or an average of 1 year.]
Durability of response is measured by relapse-free survival (RFS). RFS is defined as the amount of time a patient remains in remission after having achieved a CR or CRi
- Overall Survival of Patients who received the combination of CPX-351 and glasdegib [Time from screening biopsy for up to 12 months after the last patient is enrolled or until death from any cause, whichever came first.]
To evaluate the overall survival of patients with newly diagnosed with Acute Myeloid Leukemia (AML) with Myelodysplastic Syndrome (MDS) related changes or treatment-related AML.
- Time to normal hematopoiesis as assessed by laboratory studies [From the start date of treatment until laboratory studies confirmation of normal hematopoiesis or an average of 1 year]
To evaluate the time to normal hematopoiesis, process by which blood cells are formed, as determined by laboratory studies inclusive of complete blood counts (CBCs)
- Number of participants who go on to receive an allogenic hematopoietic stem cell transplant [Up to 3 years]
This is defined as the number of participants who continue on to receive an allogenic hematopoietic stem cell transplant after induction, re-induction, or consolidation.
Eligibility Criteria
Criteria
Inclusion Criteria:
- Previously untreated therapy-related AML or AML with myelodysplastic related changes as described by World Health Organization (WHO) 2016
-
AML arising in MDS (including CMML) or MDS/MPN syndrome
-
AML with MDS-related cytogenetic abnormalities (Appendix A, metaphase FISH allowable as surrogate for cytogenetics)
-
AML with multi-lineage dysplasia involving the presence of 50% or more dysplastic cells in at least two cell lines and in the absence of mutation in NPM1 or biallelic CEBPA (as per WHO 2016)
-
Adults 18 years of age or older
-
ECOG performance status 0 to 2
-
Adequate organ function as defined as:
-
Left Ventricular Ejection Fraction (LVEF) > 50%
-
Serum total bilirubin < 2.0 mg/dL, unless considered due to Gilbert's disease or leukemic involvement
-
AST, ALT and alkaline phosphatase < 3 times the upper limit of normal, unless considered due to leukemic involvement
-
Serum creatinine < 2.0 mg/dL, or creatinine clearance > 40 mL/min based on Cockcroft-Gault GFR

-
Ability to understand and the willingness to sign a written informed consent or subject's legally authorize representative (LAR) has provided informed consent prior to any study-specific activities/procedures being initiated when the subject has any kind of condition that, in the opinion of the investigator, may compromise the ability of the subject to give written informed consent
-
Women of child-bearing potential and men with partners of child-bearing potential must agree to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication
-

-
Male subjects must agree to use a latex condom during sexual contact with females of childbearing potential even if they have had a successful vasectomy starting with the first dose of study therapy through 120 days after the last dose of study therapy
- Leukapheresis, corticosteroid and hydroxyurea are permitted as initial management of hyperleukocytosis at the investigator's discretion for up to 7 days after starting study therapy.
