Glasdegib-Based Treatment Combinations for the Treatment of Patients With Relapsed Acute Myeloid Leukemia Who Have Undergone Hematopoietic Cell Transplantation

A Pilot/Phase 1b Study of Glasdegib-Based Treatment Combinations in Adult Patients With Relapsed AML Post Allogeneic Hematopoietic Cell Transplantation

This phase Ib trial evaluates the best dose and effect of glasdegib in combination with venetoclax and decitabine, or gilteritinib, bosutinib, ivosidenib, or enasidenib in treating patients with acute myeloid leukemia that has come back (relapsed) after stem cell transplantation. Chemotherapy drugs, such as venetoclax and decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Glasdegib, bosutinib, ivosidenib, and enasidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Glasdegib inhibits the Sonic the Hedgehog gene. Venetoclax inhibits BCL-2 gene. Bosutinib is a tyrosine kinase inhibitor that inhibits BCR-ABL gene fusion. Ivosidenib inhibits isocitrate dehydrogenase-1 gene or IDH-1. Enasidenib inhibits isocitrate dehydrogenase-2 gene or IDH-2. This study involves an individualized approach that may allow doctors and researchers to more accurately predict which treatment plan works best for patients with relapsed acute myeloid leukemia.

OUTLINE: This is a dose escalation study of glasdegib maleate (glasdegib) followed by a dose-expansion study.

MOLECULAR DIAGNOSIS SEGMENT: Patients receive glasdegib orally (PO) once daily (QD) for at least 14 days until their acute myeloid leukemia (AML) TAC recommendation is made and they are either consented to a treatment arm in the Treatment Segment or go off study.

TREATMENT SEGMENT: Patients are assigned to 1 of 5 arms.

CHAPTER 2: Patients receive glasdegib PO QD and gilteritinib fumarate (gilteritinib) PO QD on days 1-28. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

CHAPTER 3: Patients receive glasdegib PO QD and bosutinib monohydrate (bosutinib) PO QD on days 1-28. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

CHAPTER 4: Patients receive glasdegib PO QD and ivosidenib PO QD on days 1-28. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

CHAPTER 5: Patients receive glasdegib PO QD and enasidenib mesylate (enasidenib) PO QD on days 1-28. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ability to obtain a molecular diagnosis (Molecular Diagnosis Segment)	Outcome will be dichotomized based on return in =< 10 calendar days (Yes/No). Assessed by the proportion of successful participants.	From study enrollment to return of Molecular Diagnosis Report, assessed up to 30 days
Ability to make a treatment arm assignment by the Treatment Assignment Committee (TAC) (Molecular Diagnosis Segment)	Outcome will be dichotomized based on return in =< 14 calendar days (Yes/No). Assessed by the proportion of participants who receive treatment assignment from TAC.	From enrollment to treatment arm assignment by the TAC, assessed up to 30 days
Incidence of adverse events (Treatment Segment)	Toxicity will be graded according to the National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Safety will be based on the assessment of dose limiting toxicity during cycle 1 and cycle 2. Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment and reversibility or outcome.	Up to 30 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of patients with successful sequencing (Molecular Diagnosis Segment)	Successful sequencing is defined as passing quality control, and will be determined by City of Hope pathology among those with less than 20% blasts in the marrow aspirate.	Up to 30 days
Proportion of patients with successful treatment arm registration (Molecular Diagnosis Segment)	Successful placement defined as the enrollment of a participant into one of the treatment arms.	Up to 30 days
Incidence of adverse events (Molecular Diagnosis Segment)	Toxicity will be graded according to the NCI-CTCAE version 5.0. Safety will be based on the assessment of unacceptable toxicity during glasdegib monotherapy. Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment and reversibility or outcome.	Up to 30 days
Overall response (Treatment Segment)	Response will be based on Dohner et al., 2017 criteria. Response dates recorded will be the date of the first of 2 successive bone marrows showing said response. For this trial, will assess the complete remission rate calculated as the percent of evaluable patients that have confirmed complete response (CR) or incomplete blood count recovery (CRi). 95% Clopper Pearson binomial confidence interval will be calculated. Response rates will also be explored based on number/type of prior therapy(ies).	Up to the date of the first of 2 successive bone marrows showing said response, assessed up to 30 days
Duration of remission (Treatment Segment)		Time from the first of two consecutive bone marrow aspirates showing CR or CRi until such time as the bone marrow or peripheral blood mononuclear cells shows signs of relapse, assessed up to 30 days

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in leukemia stem cell (LSC) burden (Treatment Segment)	Measured by limiting dilution and engraftment into non-obese diabetic severe combined immunodeficiency gamma severely immunocompromised mice. Graphical statistics will be used. To assess the association between the LSC reduction and the response to the treatment, the median change from baseline to post-treatment (2 cycles) in engraftment levels of secondary mice recipients (n=12 mice/patient, 6 females and 6 males) will be compared by two-sample t test between response and non-response patient groups as LSC donors, across all treatment arms. The effect of treatment on the target genes will be assessed for each arm by linear mixed models (pre- versus multiple post-treatment time points) as well.	Baseline up to post-treatment (2 cycles) (each cycle = 28 days)
