What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing Mepolizumab, a medication that reduces inflammation, in patients with chronic spontaneous urticaria who do not respond well to typical treatments. The drug works by decreasing the number of certain immune cells that cause hives and itching.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does require that you have not used Xolair before. It's best to discuss your current medications with the trial team.

Is Mepolizumab safe for humans?

Mepolizumab has been used for conditions like severe asthma, and while it is generally considered safe, there is a risk of serious allergic reactions (anaphylactic reactions) in some people. Careful monitoring after administration is recommended to manage any potential allergic reactions. ^{1 2 3 4 5}

How does the drug mepolizumab differ from other treatments for hives?

Mepolizumab is unique because it is a monoclonal antibody that targets interleukin-5 (IL-5), a protein involved in the activation of eosinophils (a type of white blood cell), which are key in inflammation. While it is primarily used for severe eosinophilic asthma, its mechanism of reducing eosinophil activity may offer a novel approach for treating hives, especially if they are related to eosinophilic activity. ^{1 5 6 7 8}

What data supports the effectiveness of the drug Mepolizumab for treating hives?

Mepolizumab has shown effectiveness in reducing symptoms in conditions with high levels of eosinophils (a type of white blood cell), such as severe asthma and hypereosinophilic syndrome, which suggests it might help with hives if they are related to eosinophils. ^{9 10 11 12 13}

Are You a Good Fit for This Trial?

This trial is for adults over 18 with chronic spontaneous urticaria (hives) that doesn't get better with antihistamines. Participants must be in good health overall and able to follow the study's procedures. Pregnant or nursing women, those planning pregnancy soon, people allergic to Nucala, severe asthma patients on high-dose steroids, and anyone who has used Xolair can't join.

Inclusion Criteria

My condition didn't improve with allergy pills.

I am willing and able to follow the study's requirements.

Exclusion Criteria

Known history of adverse reaction to Nucala

Pregnant or nursing women

Women planning a pregnancy within the study period

What Are the Treatments Tested in This Trial?

Interventions

• Mepolizumab

Trial Overview The trial is testing the effectiveness of a medication called Nucala (Mepolizumab) for treating chronic spontaneous urticaria when standard treatments like antihistamines don't work. It's an early-stage study aimed at gathering initial data on how well this drug works for hives.

How Is the Trial Designed?

Group I: Treatment Arm Experimental Treatment 1 Intervention

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

Published Research Related to This Trial

Mepolizumab, a monoclonal antibody that neutralizes IL-5, has shown effectiveness in reducing eosinophil levels in patients with eosinophilic diseases, including asthma and hypereosinophilic syndrome.

While initial trials showed limited impact on asthma symptoms, more recent studies indicate that mepolizumab significantly reduces asthma exacerbations and improves quality of life in patients with severe eosinophilic asthma.

Mepolizumab and eosinophil-mediated disease. Walsh, GM.[2019]

Mepolizumab significantly reduced the rate of clinically significant asthma exacerbations in Korean patients with severe eosinophilic asthma, demonstrating its efficacy in this population.

The safety profile of mepolizumab in Korean patients was consistent with that observed in the overall population, indicating it is a safe treatment option for severe eosinophilic asthma.

In a study of 351 patients with severe eosinophilic asthma, initiating treatment with mepolizumab led to a significant reduction in the use of high-dose inhaled corticosteroids (ICS) over a 12-month period, with 49% of patients reducing or discontinuing ICS.

Patients who discontinued ICS after starting mepolizumab experienced lower rates of chronic oral corticosteroid (OCS) use, fewer exacerbations, and reduced reliance on short-acting β2-agonists, indicating improved clinical outcomes.
