New drug for stubborn hives passes blood pressure check in phase 3 trial
NCT ID NCT05795153
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested a drug called remibrutinib in 144 adults with chronic spontaneous urticaria (hives lasting over 6 months) that standard antihistamines couldn't control. Participants took a 25 mg tablet twice daily for up to 12 weeks. The main goal was to see if the drug affected blood pressure, using a 24-hour monitor. The study also tracked overall safety and how well the drug controlled hives.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- remibrutinib (a drug taken as a tablet twice daily)
- What this could lead to
- If successful, this could confirm that remibrutinib is a safe and effective option for people with chronic hives that don't respond to standard antihistamines.
- What could go wrong
- This is a completed Phase 3 study, but it primarily measured blood pressure changes, not long-term effectiveness or safety. The results may not apply to all patients, and side effects are still being evaluated.

Key Inclusion Criteria: * Signed informed consent obtained prior to participation in the study * Male and female adult participants \>= 18 years of age * CSU duration for \>= 6 months prior to screening (defined as the onset of CSU determined by the Investigator based on all available supporting documentation). * Diagnosis of CSU inadequately controlled by second generation H1-AH at the time of baseline (Day 1) * Documentation of hives within three months before baseline (either at screening and/or at baseline (Day 1); or documented in the participants' medical history). * Willing and able to complete an Urticaria Patient Daily Diary (UPDD) for the duration of the study and adhere to the protocol * Participants had no more than 2 missing UPDD entries (either morning or evening) in the 7 days prior to baseline (Day 1). Key Exclusion Criteria: * Participants unable to tolerate 24-hour ambulatory blood pressure measurement using automatic ABPM device * Ongoing or past history of hypertension and/or SBP \>= 140 or =\< 90 OR DBP \>= 90 or =\< 60 mmHg at screening * Participants working night shifts * Participants taking/requiring medications prohibited by the protocol (including those known to interfere with blood pressure assessments in the study) * Evidence of clinically significant cardiovascular, neurological, psychiatric, pulmonary, renal, hepatic, endocrine, metabolic, hematological disorders, gastrointestinal disease or immunodeficiency that, in the Investigator's opinion, would compromise the safety of the participant, interfere with the interpretation of the study results or otherwise preclude participation or protocol adherence of the participant.
