Filter by:A safety extension study to evaluate the long-term safety of QGE031 240 mg s.c. given every 4 weeks for 52 weeks in Chronic Spontaneous Urticaria (CSU) patients who completed study CQGE031C2201
Evaluate the proportion of patients with an urticaria control test [UCT] score of greater than or equal to 12 at Week 12.
This is a placebo and active-controlled phase 2b dose-finding study to evaluate efficacy and safety of QGE031 monthly subcutaneous injections as add-on therapy in patients with Chronic Spontaneous Urticaria.
Chronic Spontaneous Urticaria (CSU), defined by the persistence of daily or almost daily urticaria over 6 weeks, affects 0.5% to 1% of the general population. In more than half of the cases, it lasts more than 2 years. It can dramatically alter the quality of life, in particular sleep, and generates numerous consultations and hospitalizations, with an average annual cost per patient close to 2000 euros in Europe. The treatment is based on the validated 2nd generation anti-H1 antihistamines dosage of one tablet per day whose effectiveness is satisfactory, however about half the time. In cases of severe CSU refractory to treatment with anti-H1 licensed dosage, few therapeutic alternatives exist, still off-label: the monketulast, an anti-leukotriene, ciclosporine or methotrexate, as immunosuppressants. Various studies have shown the important benefit of an expensive anti-IgE biological: the omaluzimab. Several open studies have also suggested superior efficacy and good tolerability of anti-H1 in higher dosage (double, triple or quadruple) including levocetirizine. The off-label use of these high dosages of anti-H1 is growing very rapidly in France, tending to replace the use of anti-H1 first generation or substitution to another 2nd generation anti-H1 recommended by the French Society of Dermatology. This study, under the aegis of the Urticaria Group of the French Society of Dermatology, intends to compare the efficacy of levocetirizine 4 tablets/day versus 1 tablet/day in the treatment of CSU resistant to anti-H1 licensed dosage.
This trial assessed the efficacy of optimized re-treatment therapy with omalizumab (150mg or 300mg) after relapse, in participants with Chronic Spontaneous Urticaria who were clinically well-controlled following their first course of treatment with omalizumab (150mg or 300mg). The study also assessed the benefit of uptitrating to 300mg dose in participants who were not well-controlled following their initial course of treatment with omalizumab 150mg, as well as the benefit of treatment extension of those patients who were not well-controlled following their initial course of treatment with omalizumab 300mg.
The aim of this study is to investigate the pathophysiological mechanism of omalizumab in patients with documented chronic urticaria who have complaints under standard antihistamine treatment. With this study the investigators will assess the correlation between Fc-IgE receptor downregulation as well as functionality and clinical response to omalizumab treatment in patients with chronic urticaria. This may be an approach for other diseases as well, where Fc-IgE receptor crosslinking are essential. The treatment time is set for a total of 4 monthly applications of omalizumab. According to the dosage recommendations of recent studies, fixed doses of 300 mg omalizumab are administered subcutaneously.
This study will assess the impact of omalizumab on the quality of life improvement when added to the standard therapy in refractory patients suffering from chronic spontaneous urticaria and angioedema.
