Study Description

Brief Summary:

This phase 2 study evaluates the sequential combination of decitabine then midostaurin for the treatment of newly-diagnosed acute myeloid leukemia (AML) in older patients.

Condition or disease	Intervention/treatment	Phase
Acute Myeloid Leukemia (AML) With Multilineage Dysplasia Following Myelodysplastic Syndrome, in Adults; AML (Adult) With 11q23 (MLL) Abnormalities; AML (Adult) With Del (5q); AML (Adult) With Inv (16) (p13; q22); AML (Adult) With t (16;16) (p13; q22); AML (Adult) With t (8; 21) (q22; q22); Secondary AML (Adult); Untreated AML (Adult)	Drug: Decitabine; Drug: Midostaurin	Phase 2

Detailed Description:

Treatment with decitabine, a cytidine analog, then midostaurin, a multi-target protein kinase inhibitor (PKI), may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Decitabine, then midostaurin; INDUCTION THERAPY Subjects receive decitabine intravenously (IV) over 1 hour on days 1 to 10 and midostaurin orally (PO) twice daily (BID) on days 11 to 28. Treatment repeats every 28 days until documented bone marrow response is achieved or for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patients achieving documented bone marrow response by course 6 continue treatment with induction therapy; patients achieving response after course 6 proceed to post-remission therapy. POST-REMISSION THERAPY Subjects receive decitabine IV over 1 hour on days 1 to 5 and midostaurin PO BID on days 6 to 28. Treatment repeats every 28 days for up to 12 courses (including induction therapy) in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for up to 1 year.

Drug: Decitabine; Given IV; Other Names: 5-aza-dCyd; 5AZA; DAC; Dacogen; Drug: Midostaurin; Given PO; Other Names: N-benzoyl-staurosporine; PKC412

Outcome Measures

Primary Outcome Measures :

1. Complete Remission (CR) Rate [ Time Frame: Up to 1 year ]

   The complete remission (CR) rate, or complete response rate, is reported as the sum and proportion of participants that achieved CR or CR with incomplete blood count recovery (CRi), within 12 months of starting midostaurin treatment.

   • Complete remission (CR): Bone marrow blasts < 5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count (ANC) > 1000/μL; platelet count > 100,000/μL; independence of red cell transfusions.
   • CR with incomplete recovery (CRi): All CR criteria except for ANC < 1000/μL or platelet count < 100,000/μL.
   • Partial remission (PR): All hematologic criteria of CR; except decrease of bone marrow blast percentage to 5% to 25%; and decrease of pretreatment bone marrow blast percentage by at least 50%.

Secondary Outcome Measures :

1. Overall Response Rate (ORR) [ Time Frame: up to 1 year ]

   Overall response rate (ORR) was assessed as the number and proportion of participants who received midostaurin and achieved a partial response (PR), complete response (CR), or complete response with incomplete blood count recovery (CRi).

   • Complete remission (CR): Bone marrow blasts < 5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count (ANC) > 1000/μL; platelet count > 100,000/μL; independence of red cell transfusions.
   • CR with incomplete recovery (CRi): All CR criteria except for ANC < 1000/μL or platelet count < 100,000/μL.
   • Partial remission (PR): All hematologic criteria of CR; except decrease of bone marrow blast percentage to 5% to 25%; and decrease of pretreatment bone marrow blast percentage by at least 50%.
2. Median Duration of Response (DoR) [ Time Frame: Up to 1 year ]

   Response was assessed by evaluations conducted every 3 cycles (12 weeks). Once documented as partial response (PR), complete response (CR), or complete response with incomplete blood count recover (CRi), response status was confirmed every 12 weeks. In responding participants, duration of response was assessed from the start of treatment through the last documented response before documented progressive disease or death. The outcome is reported as the median value for duration of response, with full range.

   • CR: Bone marrow blasts < 5%; absence of blasts with Auer rods; absence of extramedullary disease; ANC > 1000/μL; platelet > 100,000/μL; independence of red cell transfusions.
   • CRi: All CR criteria except ANC < 1000/μL or platelet count < 100,000/μL.
   • PR: All hematologic criteria of CR; except decrease of bone marrow blast percentage to 5% to 25%; & decrease of pretreatment bone marrow blast percentage by at least 50%.
3. Progression-free Survival (PFS) [ Time Frame: Up to 2 years ]

   Progression-free survival (PFS) is reported as the number and proportion of participants who did not receive hematopoietic cell transplantation, and who did not experience disease progression or death for any reason within 2 years after starting midostaurin treatment.

   Progressive disease: Bone marrow blasts ≥ 5%; or reappearance of blasts in the blood; or development of extramedullary disease.

4. Overall Survival (OS) [ Time Frame: Up to 2 years ]
   Survival is reported as the number and proportion of participants that received midostaurin who remained alive 2 years after starting midostaurin treatment.
