Rhapsido receives FDA approval for targeted BTKi treatment for chronic spontaneous urticaria

Novartis announces that Rhapsido received approval as an oral treatment for adult patients with chronic spontaneous urticaria who remain symptomatic despite H1 antihistamine treatment. Rhapsido is a pill taken twice daily and does not require injections or lab monitoring. It is the first FDA-approved Bruton’s tyrosine kinase inhibitor for CSU.

“CSU is a serious disease that can cause debilitating symptoms and unpredictable flares. It’s difficult to diagnose and manage,” said Mark Lebwohl, MD, Dean for Clinical Therapeutics at the Icahn School of Medicine at Mount Sinai and member of the steering committee for the remibrutinib REMIX Phase III clinical trial program. “Remibrutinib represents a new way of treating CSU. By blocking the activity of BTK, remibrutinib stops a key pathway of the immune response in CSU. This is an exciting new option that has the potential to help a broad range of patients get fast relief.”

Note that CSU symptoms are unpredictable, recurring for six weeks or more without an identified cause. Diagnosis can take up to 24 months. Many CSU patients say their symptoms negatively impact their sleep, work, and mental health. Antihistamines are the first-line treatment, but over half of patients still have symptoms, even at higher doses. Injectable treatments exist for those who don’t respond to antihistamines, yet fewer than 20% of eligible patients receive them.

“The approval of remibrutinib is an important development in CSU care. It quickly reduces symptoms, offering patients control of the hives and itching that they experience on a daily basis,” said Giselle Mosnaim, MD, MS, an Allergist and Immunologist from Endeavor Health, Clinical Associate Professor at the University of Chicago Pritzker School of Medicine and REMIX trial investigator. “This is significant because it expands beyond existing injectable treatments and gives patients an oral option that can easily be incorporated into their daily lives.”

“Many CSU patients feel misunderstood and settle for treatments that don’t fully meet their needs,” said Lynda Mitchell, CEO of Allergy & Asthma Network. “We support new treatment options that empower patients to choose what works best for them. This convenient new oral therapy offers a promising new way to manage CSU and potentially improve daily life for those living with this challenging condition.”
