The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Novartis ( Novartis Pharmaceuticals )
  Purpose
This study will investigate if the drug midostaurin taken orally twice daily is effective and safe in treating patients with aggressive systemic mastocytosis or mast cell leukemia with or without an additional hematological neoplasm.

Condition Intervention Phase
Leukemia Drug: Midostaurin (PKC412) Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Single Arm, Phase II, Open-Label Study to Determine the Efficacy of 100mg Twice Daily Oral Dosing of Midostaurin Administered to Patients With Aggressive Systemic Mastocytosis or Mast Cell Leukemia +/- an Associated Hematological Clonal Non-Mast Cell Lineage Disease

Primary Outcome Measures:
  • Overall Response Rate (ORR) [ Time Frame: 6 months ]
    The ORR was defined as the percentage of participants who classified as confirmed responders (major response (MR) or partial response (PR). A major responder had complete resolution of at least one C-Finding and no progression in other C-Findings. A partial responder showed a measurable improvement in one or more C-Finding(s) without confirmed progression in other C-Findings. A C-Finding was a Clinical Finding, which was considered by the investigator and corroborated by the Study Steering Committee (SSC) Chairperson or designee, attributable to the mast cell disease component and not the associated hematological clonal non-mast cell lineage disease (AHNMD) component or any other cause.


Secondary Outcome Measures:
  • Duration of Response [ Time Frame: 5 years ]
  • Time to Response [ Time Frame: 5 years ]
  • Overall Survival (OS) [ Time Frame: 5 years ]

Enrollment: 116
Actual Study Start Date: October 15, 2008
Estimated Study Completion Date: July 12, 2017
Primary Completion Date: December 1, 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Midostaurin (PKC412)
Midostaurin was administered at a dose of 100 mg twice daily (bid) in continuous cycles of 28 days until disease progression, intolerable toxicity or withdrawal due to any cause, whichever occurred first.
Drug: Midostaurin (PKC412)
Midostaurin was provided as 25 mg soft gelatin capsules for oral administration.

Criteria

Key Inclusion Criteria:

  • ECOG performance status of 0-3
  • Life expectancy > 12 weeks
  • ECG: QTc interval ≤ 450 ms
  • Meeting the following laboratory values:
  • AST and ALT must be ≤ 5 x Upper Limit of Normal (ULN) if this elevation is solely due to ASM/MCL, otherwise AST, ALT must be ≤ 2.5 x ULN
  • Serum Bilirubin must be ≤ 3 x Upper Limit of Normal (ULN) if this elevation is solely due to ASM/MCL, otherwise serum bilirubin must be

    • 1.5 x ULN

Key Exclusion Criteria:

  • Any other concurrent severe known disease (except carcinoma in-situ) concurrent severe and/or uncontrolled medical condition including congestive heart failure grade III or IV according to the NYHA classification or with ejection fraction < 50%, etc.
  • Patients with any pulmonary infiltrate including those suspected to be of infectious origin. Exception: Patients with a pleural effusion related to the disease under study as confirmed by the investigator are permitted to enter the study
  • Patients who have demonstrated relapse to 3 or more prior regimens of SM treatment (not including those given for supportive care)
  • Patients who have received any investigational agent, chemotherapy, interferon-α, or 2-chlorodeoxyadenosine (2-CdA, cladribine) within 30 days prior to first dose
  • Patients who have ASM with eosinophilia and known positivity for the FIP1L1-PDGFRα fusion unless they have demonstrated relapse or disease progression on prior imatinib therapy
