Urticaria

The CUPID-C randomized clinical trial confirmed CUPID-A results, with dupilumab significantly reducing urticaria in anti-IgE–naive individuals with CSU.

The 2024 global update for urticaria preserves the stepwise algorithm and clarifies evidence on biomarkers, provocation testing, pediatric care, and emerging therapies.

This study analyzed the Chronic Urticaria Registry (CURE), evaluating CSU treatment patterns and looking into unmet needs in real-world practice.

Jasper Therapeutics has released new, positive findings on the use of briquilimab, a novel antibody therapy targeting KIT (CD117), in patients with CSU.

Investigators look at the ways in which CSU impacts family members supporting those with CSU, using the Family Dermatology Life Quality Index (FDLQI).

In this Q&A, Soong discusses phase 2 results on povorcitinib, a JAK1 inhibitor that provides rapid relief from chronic spontaneous urticaria symptoms.

RAPT Therapeutics and Shanghai Jeyou Pharmaceutical announced these new findings on RPT904 (JYB1904) in chronic spontaneous urticaria.

The FDA has approved remibrutinib, a new oral treatment for chronic spontaneous urticaria, offering hope for patients unresponsive to antihistamines.

A compilation of 14 trials presented as late-breaking data at EADV 2025 Congress.

These new data, presented at EADV, highlight remibrutinib’s impact on specific IgG autoantibody levels in individuals with chronic spontaneous urticaria (CSU).

Meta-analysis finds omalizumab and remibrutinib most effective for chronic urticaria unresponsive to antihistamines; cyclosporine has greater risks.

A new analysis found a 0.78% prevalence of CSU in US adults, exceeding earlier estimates, and revealed significant mental, physical, and work-related burdens.

Dupilumab's approval marks the first new, targeted therapy for CSU in more than a decade and is the 7th indication for a disease with underlying type 2 inflammation.

Counting down the most impactful news at major medical meetings, it’s the HCPLive Five! This episode focuses on 5 key dermatology updates from the 2025 American Academy of Allergy, Asthma, and Immunology (AAAAI)/World Allergy Organization (WAO) Joint Congress.

Panelists discuss how Bruton tyrosine kinase (BTK) inhibitors appear to offer faster symptom relief and higher complete response rates compared with current chronic spontaneous urticaria (CSU) treatments like antihistamines and omalizumab while potentially requiring less frequent dosing and showing favorable safety profiles.

Panelists discuss how rilzabrutinib shows promise in phase 2 trials with rapid improvements in disease activity scores (UAS7 and ISS7) starting from week 1 and a favorable safety profile, setting expectations for the upcoming phase 3 studies to confirm these initial findings.

Bernstein also discussed other unmet needs in the field and how his center is working to address them.

Casale discussed data from the phase 3 LIBERTY-CSU CUPID studies evaluating dupilumab’s use in urticaria.

Panelists discuss how chronic spontaneous urticaria (CSU) significantly impacts patients’ quality of life through persistent itching, unpredictable flares, sleep disruption, emotional distress, and daily activity limitations, underscoring the need for effective disease control.

Panelists discuss how remibrutinib demonstrated rapid and sustained efficacy in the REMIX-1 and -2 trials through significant improvements in disease activity scores (UAS7, ISS7, HSS7) starting at week 1 and maintained through 52 weeks, with nearly half of patients achieving complete symptom resolution (UAS7 = 0) by week 52, while maintaining a favorable safety profile throughout the study period.

Metz shared highlights from 2 presentations he gave on barzolvolimab’s efficacy at the AAAAI/WAO Joint Congress.

Panelists discuss how pharmacological Bruton tyrosine kinase (BTK) inhibition with agents like remibrutinib appears safer than genetic BTK deficiency (X-linked agammaglobulinemia [XLA]), as clinical studies show the drug doesn't significantly impact immunoglobulin levels or infection rates in patients with chronic spontaneous urticaria (CSU), unlike the severe immunodeficiency seen in XLA.

Panelists discuss how newer Bruton tyrosine kinase (BTK) inhibitors being developed for chronic spontaneous urticaria (CSU), particularly remibrutinib (in phase 3 trials) and rilzabrutinib (in phase 2), are designed to be more selective than earlier oncology-focused BTK inhibitors, potentially reducing off-target effects like bleeding, cardiovascular complications, and GI issues.

By week 52, remibrutinib and placebo-to-remibrutinib groups had similar levels of urticaria control.

Panelists discuss how Bruton tyrosine kinase (BTK) inhibitors offer a novel upstream approach, in contrast to current treatments that work downstream by either blocking released mediators (antihistamines), neutralizing circulating IgE (omalizumab), or broadly suppressing immune responses (immunosuppressants).
