The aim of this study is to evaluate the efficacy in terms of clinical and biological response rates of Cladribine plus Pegylated Interpheron alpha-2a therapy in patients with advanced systemic mastocytosis carrying D816V or other exon 17 KIT mutations.
Drug: Cladribine and pegylated interpheron alpha-2a
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||Subcutaneous Cladribine Plus Pegylated Interpheron Alfa-2a in Advanced Systemic Mastocytosis With D816V and Other Exon 17 KIT Mutations.
Primary Outcome Measures:
Secondary Outcome Measures:
- To determine the effect of therapy on serum tryptase levels and other altered peripheral blood parameters due to mastocytosis. [ Time Frame: 6 months ]
Serum tryptase and any other mastocytosis-related altered biochemical parameter at diagnosis will be measured monthly until the end of therapy.
- To evaluate the effect of therapy on mast cell-mediator release symptoms: pruritus, flushing, gastrointestinal symptoms or anaphylaxis). [ Time Frame: 6 months ]
Specific questionnaires regarding mast cell-mediator release symptoms will be filled monthly by each patient until the end of therapy.
- To determine de safety of combined therapy with low doses of cladribine plus pegylated interpheron alpha-2a. [ Time Frame: 6 months ]
Potentially drugs-related adverse events will be recorded in each case following accepted criteria (NIH CTCAE).
- To evaluate the effect of therapy on mastocytosis skin lesions. [ Time Frame: 6 moths ]
Evaluation of cutaneous response will be assessed by macroscopic inspection including photographs and by skin immunohistochemestry.
- To evaluate the effect of therapy on mastocytosis-related organomegalies. [ Time Frame: 6 months ]
Evaluation of organomegalies response will be assessed by abdominal ultrasound and/or computerized tomography.
- To evaluate the effect of therapy on mastocytosis-related bone alterations. [ Time Frame: 6 months ]
Evaluation of bone response will be assessed by X-ray survey and/or computerized tomography.
