Remibrutinib Safety Profile and Tolerability in Symptomatic Dermographism
Through week 24 of clinical trials, remibrutinib demonstrated a consistent safety profile in SD and CSU, according to Novartis. The most common adverse events (incidence ≥3%) were nasopharyngitis (nasal congestion, sore throat, and runny nose), bleeding, headache, nausea, and abdominal pain. Novartis stated no routine laboratory monitoring is required.¹
RemIND also evaluated remibrutinib in additional forms of chronic inducible urticaria, including cold urticaria and cholinergic urticaria. Novartis plans to submit the full RemIND data set to health authorities globally, where appropriate.¹
Frequently Asked Questions
What is remibrutinib approved for?
The FDA has approved remibrutinib for adults with SD and CSU inadequately controlled by H1 antihistamines.¹ The SD indication was announced October 7, 2026.
How does remibrutinib work?
Remibrutinib is an oral, highly selective BTKi. It blocks the BTK pathway involved in the release of histamine, a key driver of hives (wheals) and swelling.
What did the RemIND trial show?
At week 12, 29.3% of patients with SD treated with remibrutinib achieved complete response from hives vs 14.0% with placebo (P = .0229).
Novartis also reported no liver safety signals in the phase 3 REMODEL-1 (NCT05147220) and REMODEL-2 (NCT05156281) trials of remibrutinib in relapsing multiple sclerosis, consistent with the CSU experience.¹ Those trials compared remibrutinib with teriflunomide and showed a clinically meaningful reduction in annualized relapse rates and a clinically meaningful delay in disability progression, with a favorable safety profile, according to the company.¹
Lindsey Finklea, MD, a dermatologist, adjunct professor at the University of Texas at San Antonio, and RemIND investigator, said in the news release, "Having the first FDA-approved medicine specifically for SD marks an important change in how clinicians can approach care and offers renewed hope for patients whose symptoms are not adequately controlled by H1 antihistamines."¹
Novartis reported more than 90% of adults with chronic hives have CSU or SD, making remibrutinib the only treatment indicated for both of the 2 most common forms. Remibrutinib is also approved for CSU in the EU, UK, and China.¹
In the phase 3 REMIX-1 (NCT05030311) and REMIX-2 (NCT05032157) trials of patients with CSU, remibrutinib reduced the urticaria activity score over 7 days vs placebo at week 12 (least squares mean change, −20.0 vs −13.8 in REMIX-1 and −19.4 vs −11.7 in REMIX-2; P < .001 for both).² Remibrutinib continues to be studied in hidradenitis suppurativa and food allergy.¹
