Trial Outcomes & Findings for Omalizumab in Severe and Refractory Solar Urticaria (NCT NCT02262130)

NCT ID: NCT02262130

Last Updated: 2018-10-12

Results Overview

Proportion of patients with minimal urticarial dose (MUD) increased compared to baseline, under experimental conditions (assessed by phototesting). A small area of skin is exposed to increasing UVA doses with a solar simulator until an allergic reaction appears. The lower UVA dose triggering the urticaria is the MUD.

SECONDARY outcome

Timeframe: 4 and 12 weeks after the end of treatment

Population: 1 patient withdrawn between week 12 and week 20 (discontinuation)

Proportion of patients for whom the treatment with omalizumab allowed achieving DLQI \< 6. The index extends from 0 to 30: 0 - 1 = no effect at all on patient's life / 2 - 5 = small effect on patient's life / 6 - 10 = moderate effect on patient's life / 11 - 20 = very large effect on patient's life / 21 - 30 = extremely large effect on patient's life
