Brief Summary:
The purpose of this study is to characterize the regimen limiting toxicities (RLT) and recommended Phase 2 dose (RP2D) of indoximod in patients with newly diagnosed AML receiving remission induction chemotherapy with cytarabine and idarubicin.

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Drug: Idarubicin Drug: Cytarabine Drug: Indoximod Freebase Drug: Indoximod HCL Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Trial of Indoximod in Combination With Idarubicin and Cytarabine in Patients With Newly Diagnosed Acute Myeloid Leukemia (AML)
Study Start Date : July 2016
Estimated Primary Completion Date : July 2018
Estimated Study Completion Date : July 2018


Arm Intervention/treatment
Experimental: Phase 1a
Patients enrolled in this arm will receive standard induction and consolidation chemotherapy (7+3) with Indoximod (freebase formulation). These patients will additionally receive maintenance therapy with indoximod for 6 months after consolidation therapy. The indoximod dose will be studied in up to 4 dose levels.

Experimental: Phase 1b
Patients enrolled in this arm will receive standard induction and consolidation chemotherapy (7+3) with Indoximod (HCL formulation). These patients will receive maintenance therapy with indoximod for 6 months after consolidation therapy. The indoximod dose will be studied in up to 4 dose levels.

Primary Outcome Measures :
  1. Safety assessed by development of RLT, AEs and laboratory parameters of indoximod. [ Time Frame: 6 months ]
    Phase 1

  2. Comparison of serum concentrations (Cmax/Steady State) of indoximod freebase and indoximod salt formulation. [ Time Frame: 6 months ]
    Phase 1


Secondary Outcome Measures :
  1. Measurable Residual Disease Rate [ Time Frame: 2 years ]
  2. Clinical response rate [ Time Frame: 2 years ]
  3. Duration of complete response [ Time Frame: 2 years ]
  4. Event free survival [ Time Frame: 2 years ]
    Time on study to induction failure, relapse or death

  5. Cumulative incidence of relapse (CIR) [ Time Frame: 2 years ]
  6. Overall survival (OS) [ Time Frame: 2 years ]
  7. Proportion of AML patients who become eligible for bone marrow transplantation [ Time Frame: 2 years ]
  8. Frequency and severity of adverse events [ Time Frame: 2 years ]
  9. Pharmacokinetics: Serum concentrations (Cmax/Steady State) [ Time Frame: 6 months ]
    Characterize the pharmacokinetics (PK) of indoximod, idarubicin and cytarabine through analysis of blood samples


Other Outcome Measures:
  1. Serum kynurenine and tryptophan levels [ Time Frame: 2 years ]
    Characterize the pharmacodynamic (PD) effect of indoximod

  2. IDO expression by immunohistochemistry in diagnostic and follow-up bone marrow biopsy specimens [ Time Frame: 2 years ]
  3. IDO protein and mRNA expression in diagnostic and follow-up bone marrow aspirate samples [ Time Frame: 2 years ]
  4. Methylation status of the IDO promoter in diagnostic and follow up bone marrow aspiration samples [ Time Frame: 2 years ]
