Arm Intervention/treatment
Experimental: 2CDA+IFN Drug: Cladribine and pegylated interpheron alpha-2a

Cladribine (0.07 mg/Kg/day) s.c for 5 consecutive days each month for a total of 6 months.Cladribine daily doses could be increased up to 0.14 mg/Kg in the fourth, fifth and sixth cycles of therapy if no objetive response is achieved after the third cycle.

Pegylated Interpheron alpha-2a (1 mcgr/Kg) s.c weekly for a total of 6 months.


Outcome Measures

Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. To evaluate the effect of therapy on bone marrow mast cell infiltration. [ Time Frame: 6 months ]
    Evaluation of bone marrow response will be assessed by immunohistochemestry, citology, flow cytometry and molecular analyses of bone marrow samples.


Secondary Outcome Measures :
  1. 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.

  2. 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.

  3. 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).

  4. 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.

  5. 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.

  6. 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.
