|Condition or disease||Intervention/treatment||Phase|
|Indolent Systemic Mastocytosis||Drug: Midostaurin,||Phase 2|
Primary: To study in a pilot phase II trial the efficacy of midostaurin administered at an oral dose of 100 mg twice daily in patients with indolent or smoldering systemic mastocytosis on mediator symptom reduction, documented by the Mastocytosis Symptom Assessment Questionnaire, measured at 3 months.
- To study whether symptom improvement persists at 6 months, and whether midostaurin can reduce mast cell infiltration in the skin and bone marrow, documented by decrease of serum tryptase, decrease of urticaria pigmentosa and decrease of bone marrow mast cells.
- To assess safety and tolerability of midostaurin in the above mentioned settings
Study design: Single arm, open label pilot phase II study.
Study population: Adult patients (n=20) with histologically documented systemic mastocytosis, indolent or smoldering subtype, with severe symptoms, not controlled by histamine 1 and 2 blockers.
Intervention: treatment with Midostaurin, twice daily 100 mg orally for 6 months continuously.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||20 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Phase II Single Arm Open Pilot Study to Demonstrate the Efficacy of Midostaurin in Symptom Improvement and Decrease of Mast Cell Burden in Patients With Indolent or Smoldering Systemic Mastocytosis.|
|Study Start Date :||August 2013|
