About this trial
This is an interventional treatment trial for Mastocytosis focused on measuring mastocytosis, indolent, handicap, wild-type, systemic, not D816V mutated
Eligibility Criteria
Inclusion Criteria:
- Patients with documented Indolent systemic mastocytosis with handicap (ISMwh) having at least 2 infiltrated* organs (skin and /or bone-marrow and/or internal organ).
- Bone-marrow, or skin or internal biopsy-documented mastocytosis and evaluable disease.
- The absence of an activating point mutation in the phosphotransferase domain of c-Kit such as D816V c-Kit mutation in at least one of the two infiltrated organs: bone marrow and/or skin and/or other tissue.
Handicap defined as at least one of the following handicaps:
- a number of flush per day ≥ 1 ,
- a pruritus score ≥ 9 ,
- a number of stools per day ≥ 4 ,
- a Pollakyuria (on a per day basis) ≥ 8 ,
- a QLQ-C30 score ≥ 83 ,
- a Hamilton rating scale for depression ≥ 12
Exclusion Criteria:
- Performance status > 2 (ECOG).
- Inadequate organ function, except if the abnormalities are due to involvement by mast cells
