Novartis’ Rhapsido® Approved by FDA for Chronic Spontaneous Urticaria
Table of Contents
Teh Food and Drug Administration has granted approval to Novartis for Rhapsido® (remibrutinib), a first-in-class oral treatment targeting chronic spontaneous urticaria (CSU). This approval offers a new therapeutic option for patients struggling with this debilitating condition.
What is Chronic spontaneous Urticaria (CSU)?
Chronic Spontaneous Urticaria, also known as chronic idiopathic urticaria, is characterized by the spontaneous appearance of hives (wheals) and/or angioedema (swelling) for more than six weeks, without an identifiable trigger. It considerably impacts quality of life, causing intense itching, discomfort, and sleep disturbances. approximately 0.1-0.3% of the population is affected by CSU.
Current treatments often involve antihistamines, but many patients do not achieve adequate symptom control with these medications alone. This is where Rhapsido® offers a significant advancement.
Rhapsido® (Remibrutinib): A Novel BTK Inhibitor
Rhapsido® (remibrutinib) is an oral Bruton’s tyrosine kinase (BTK) inhibitor. BTK plays a crucial role in mast cell activation and the inflammatory pathways that drive CSU symptoms. By selectively inhibiting BTK, remibrutinib aims to reduce the production of histamine and other inflammatory mediators, thereby alleviating hives and swelling.
unlike existing injectable treatments, Rhapsido® is administered orally, offering a more convenient treatment option for patients. It represents the only oral,targeted BTK inhibitor approved for CSU.
Clinical Trial Data & Efficacy
The FDA approval is based on data from the Phase 3 PEARL study,a randomized,double-blind,placebo-controlled trial involving 352 adults with CSU who had inadequate response to antihistamines. Key findings include:
- Significant Hives Reduction: Patients treated with Rhapsido® experienced a statistically significant reduction in weekly hive scores compared to placebo.
- itch Relief: Remibrutinib demonstrated a significant improvement in itch severity compared to placebo.
- Sustained Response: Many patients maintained symptom control throughout the treatment period.
| Endpoint | Rhapsido® (Remibrutinib) | Placebo | p-value |
|---|---|---|---|
| Mean weekly hive score change from baseline | -18.2 | -6.3 | <0.001 |
| Proportion of patients achieving complete symptom control (HSS ≤ 0) at Week 12 | 44% | 11% | <0.001 |
