Brief Summary:
This is an exploratory study designed to generate preliminary data in evaluating the efficacy of Nucala in the treatment of chronic spontaneous urticaria.

Condition or disease Intervention/treatment Phase
Chronic Spontaneous Urticaria Drug: Nucala Early Phase 1

Detailed Description:
This is an open-label, single arm exploratory study of mepolizumab in the treatment of CSU. The primary endpoint will be the mean reduction in the seven day urticaria activity score (UAS7) before and after 10 weeks of treatment with mepolizumab. Secondary endpoints will be the mean reduction of the urticaria control test (UCT) score and the weekly itch severity score (ISS) before and after treatment. Enrollment examination will include a standardized history and examination, baseline UCT score, CBC with differential, serum IgE level, chronic urticaria index, IgE Fc receptor antibody functional assay, and a 4 mm punch biopsy of lesional skin to confirm the urticarial tissue reaction includes eosinophils and is not neutrophilic predominant. Patients will discontinue all anti-histamines and start cetirizine 10 mg PO BID which may be continued throughout the study duration. Patients will be provided with a log book to track daily urticaria signs and symptoms in a standardized manner for UAS scoring. At week 0 (enrollment visit +7 days), baseline UAS7 and ISS score will be assessed and skin biopsy results reviewed. Patients with a confirmatory skin biopsy will receive 200 mg SC of mepolizumab at week 0,2,4,6,and 8. UAS-7 and weekly ISS score will be calculated at week 0, 4, 8, and 10. UCT scoring will be calculated at week 0 and at week 10. Repeat CBC with differential, serum IgE level, and measures of basophil serum activation (chronic urticaria index, IgE FC Receptor antibody functional assay) will be assessed at week 10. Attached to this document is a protocol summary.

Arm Intervention/treatment
Experimental: Treatment Arm
This is an open-label pilot investigation and all study participants are assigned to active treatment. There is no placebo arm in this study.

Other Name: Mepolizumab




Primary Outcome Measures :
  1. Mean UAS score 7 [ Time Frame: Study participants will document their CSU symptoms using a diary during the 10 week study period ]
    Study participants will document their CSU symptoms using a diary,daily scoring for a) the number of wheals [none (=0 points), <10 (=1 point), 10-50 (=2 points), or >50 per day (=3 points)], and b) the intensity of pruritus [none (=0 points), mild (=1 point), moderate (=2 points), severe (=3 points)]. The daily UAS score is summed over a week to calculate the UAS7 score (range: 0-42).


Secondary Outcome Measures :
  1. Mean reduction in ISS and UCT [ Time Frame: 10 weeks of treatment with mepolizumab ]
    The weekly itch severity score is calculated using the pruritus score of the daily UAS score summed over a week (range: 0-21). The urticaria control test (UCT) is a more recently developed and validated outcome instrument to retrospectively assess urticaria control. Each UCT item has 5 answer options scored 0-4 with low points indicating high disease activity and low disease control. The minimum and maximum UCT scores are 0-16 with 16 points indicating complete disease control.
