E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of midostaurin in patients with ASM or MCL with or without AHNMD when administered orally at a dose of 100 mg b.i.d. continuously for 6 cycles (of 4 weeks each) as measured by overall response rate |
|
E.2.2 | Secondary objectives of the trial |
to evaluate:
- duration of response
- time to response
- overall survival
- progression free survival
- safety and tolerability of midostaturin
to characterize KIT mutational status in the SM compartment and if applicabe also in the AHNMD compartment of the disease at baseline, after 6 cycles of therapy and at end of study (EOS) and explore potential association with efficacy outcomes.
To evaluate histopathologic response based on mast cell infiltration in the bone marrow (BM) and changes in serum tryptase levels as surrogate marker for histopathologic response |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Male or female pts aged ≥ 18 years of age
- ECOG performance status of 0-3
- life expectancy > 12 weeks
- ECG QTc interval ≤ 450 ms
- following lab values:
AST and ALT ≤2.5 x ULN, if caused by ASM/MCL: ≤ 5 x ULN

- patients presenting with an AHNMD requiring immediate cytoreductive therapy or targeted drugs (other than midostaurin)
- patients who have demonstrated relapse to 3 or more prior regimens of SM
