Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Midostaurin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Midostaurin may help azacitidine kill more cancer cells by making the cancer cells more sensitive to the drug. PURPOSE: This phase I/II trial is studying the side effects and best dose of midostaurin when given together with azacitidine and to see how well it works in treating elderly patients with acute myelogenous leukemia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To determine the safe and tolerable dose of midostaurin in combination with azacitidine in patients with acute myelogenous leukemia. (Phase I) II. To describe the toxicity profile of the combination of midostaurin and azacitidine in patients with acute myelogenous leukemia. (Phase I/II) III. To determine the complete and partial response rate and rate of hematologic improvement of midostaurin and 5-azacitidine in untreated acute myelogenous leukemia. (Phase I/II)

SECONDARY OBJECTIVES:

I. To describe pharmacokinetics of oral midostaurin given in combination with azacitidine on a day 8-21 schedule. (Phase I/II) II. To correlate treatment response with FLT3 mutational status in a descriptive fashion. (Phase I/II) III. To assess overall survival of patients from initiation of midostaurin-azacitidine toxicities. (Phase I/II) IV. To determine median disease-free survival of the regimen in untreated patients. (Phase II)

TERTIARY OBJECTIVES:

I. To describe signaling in CD117+ committed myeloid precursors in whole blood and bone marrow samples before and during treatment. (Phase I/II) II. To measure in vivo FLT3 inhibition using plasma inhibition assay (PIA) and Flt ligand (FL) levels in patients enrolled on this trial before and during treatment. (Phase I/II)

OUTLINE: This is a phase I, dose escalation study of midostaurin followed by a phase II study.

Patients receive azacitidine intravenously (IV) over 10-20 minutes on days 1-7 and midostaurin orally (PO) twice daily (BID) on days 8-21. Courses repeat every 28 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients must have histologic proof of active AML at time of enrollment
* Phase I and II portion: Subjects of any age with untreated AML, if not candidates for standard induction chemotherapy or with poor risk AML (i.e. preceding MDS, myeloproliferative syndromes, leukemia due to cytotoxic chemotherapy for another condition, adverse cytogenetics or complex karyotype), or any subjects \> 70 years of age with untreated AML. Acute promyelocytic leukemia (FAB M3) is excluded
* Please note: prior intensive induction therapy for acute leukemia is allowed only in the phase I portion of this study

• PHASE I PORTION ONLY: Patients of any age who have received no more than one prior attempt at induction chemotherapy (and may have received treatment consolidation), must have recovered from acute toxicities of therapy and be \>= 4 weeks from last dose of cytotoxic treatment; patients who have received prior autologous or allogeneic stem cell transplantation are not eligible; patients may have received 1 or 2 cycles of cytarabine-based therapy as attempted induction.
* Phase II portion: Patients must have not received any prior intensive induction therapy for AML.

* Intensive induction includes standard induction chemotherapy such as 7 \& 3, high dose cytarabine, mitoxantrone-etoposide, low-dose subcutaneous cytarabine.
