Primary objective:

Reduction of wheal and flare type skin reaction after standardised provocation testing assessed by volumetric and thermographic measurements.

Secondary objectives:

Improvement of additional related symptoms (e.g. pruritus) and subjective affliction as assessed by symptom score, DLQI, Itchy-QoL and VAS.

Study design:

An exploratory, randomised, double-blind, placebo controlled crossover study

Type and number of patients:

Male and female patients (n = 30) with cutaneous mastocytosis and indolent systemic mastocytosis with skin involvement

Main criteria for inclusion:

Mastocytosis patients aged 18-65 years, signed written consent, no systemic corticosteroid or other immunosuppressive therapy, no permanent severe diseases Test product, dose and mode of administration 20 mg Rupatadine or placebo before provocation testing, oral administration (tablets)

Duration of treatment:

28 days (testing will be done at the day of last treatment)

Assessment of efficacy:

1. Assessment of wheal and flare development by planimetric analyses of digital photographic, volumetric, and thermographic imaging (time lapse) before and after treatment with study medication,
2. Additional assessment of symptoms,
3. Assessment of life quality

Main criteria of evaluation:

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: Sugar Pill; All patients included in this study will be subjected at the screening visit to a standardized provocation of Darier's sign by a device for standardized provocation testing (Hartmann and Siebenhaar 2009). Patients that exhibit positive skin test reactions will be enrolled, provided that they meet all inclusion criteria and none of the exclusion criteria and that they give informed consent. Study patients will receive treatment for 28 days (minimal 25, maximal 30 days) before visit 1 and visit 2 including the same day before the provocation test (RUP 20mg/day or placebo according to randomization). All patients will receive antihistaminic rescue medication immediately after completing the testing when necessary.	Drug: Rupatadin; 20 mg, 28 days over 60 days; Other Names: Each tablet contains 10 mg RUP
Active Comparator: Rupafin; All patients included in this study will be subjected at the screening visit to a standardized provocation of Darier's sign by a device for standardized provocation testing (Hartmann and Siebenhaar 2009).
