ClinConnect Summary
This clinical trial is studying a new medication called HWH486 to see if it is safe and effective for adults suffering from chronic spontaneous urticaria (CSU), a condition that causes persistent itching and hives for more than six weeks. The trial is designed for adults between the ages of 18 and 70 who have been experiencing these symptoms despite taking standard allergy medications. Participants will need to keep a daily diary to track their symptoms throughout the study.
If you decide to join the trial, you'll receive either the study medication or a placebo (a non-active treatment) and will be closely monitored by medical professionals. It's important to note that not everyone will qualify; for example, individuals with certain other skin diseases, serious health issues, or recent use of similar medications may be excluded. This trial aims to help find new treatment options for people with CSU, so your participation could contribute to important medical research.

Eligibility criteria
- Inclusion Criteria:
- • 1. Age ≥18, ≤70 years old;
- • 2. Participants with chronic spontaneous urticaria (CSU) at the time of randomization as defined by the following: presence of itch and hives for ≥ 6 consecutive weeks prior to screening, despite second generation H1-antihistamine during this period; Urticaria Activity Score (UAS7) (range 0-42) ≥16, Hives Severity Score (HSS7) (range 0-21) ≥ 6 and Itch Severity Score (ISS7) (range 0-21) ≥ 6 during 7 consecutive days prior to randomization; CSU duration ≥6 months prior to screening (defined as the onset of CSU as determined by the investigator based on all available supporting documentation).
- • 3. Willing and able to complete the Urticaria Participant Daily eDiary (UPDD) for the duration of the study;
- • 4. Willing to take background medication and emergency medication according to the study protocol.
- • 6) Written informed consent signed voluntarily by the patient or their legal representatives.
- Exclusion Criteria:
- • 1. Previous use of HWH486 or other Bruton's tyrosine kinase(BTK) inhibitors;
- • 2. Participants having a predominant or sole trigger of their chronic urticaria (chronic inducible urticaria);
- • 3. Any other skin disease associated with chronic itching that might influence in the investigator's opinion the study evaluations and results, e.g. atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, senile pruritus or psoriasis
- • 4. With symptoms or signs of progressive or uncontrolled kidney, liver, blood, gastrointestinal, endocrine, lung, heart, neurological, psychiatric, or brain disease, or with a history of gastrointestinal bleeding that is associated with a significant risk of bleeding or coagulopathy, or is clinically significant (such as requiring hospitalization or blood transfusion), or with other chronic medical conditions that are not eligible for participation in this clinical trial, or having a history of malignancy, other than non-metastatic basal cell carcinoma or skin squamous cell carcinoma or carcinoma in situ of the cervix with appropriate treatment and no signs of recurrence;
- • 5. Clinically important laboratory test indicators are abnormal, including: abnormal blood routine: hemoglobin (Hb) \< 100g/L, or white blood cell count (WBC) \< 3.5×10\^9/L; Abnormal liver function: aspartate aminotransferase (AST) ≥1.5×ULN, or alanyl aminotransferase (ALT) ≥1.5×ULN, or total bilirubin (TBIL) ≥1.5×ULN; Abnormal renal function: creatinine (Cr) ≥1×ULN; any other laboratory test indicators that researchers think may affect the evaluation of test results;
- • 6. Active and uncontrolled viral and bacterial infections at the time of screening, such as human immunodeficiency virus(HIV), hepatitis B virus(HBV), hepatitis C virus (HCV), syphilis, tuberculosis test results, or if there are any clinical symptoms of bacterial, viral, parasitic or fungal infection requiring treatment;
- • 7. Pregnant or breastfeeding women; having pregnancy plans during the clinical trial and within 1 month after the last dose, and do not want to take medically accepted reliable contraceptive methods;
- • 8. History of allergy to any investigational therapeutic drug or its excipients;
- • 9. History or evidence of alcohol or drug abuse within the six months prior to randomization;
- • 10. Use of other immunosuppressive drugs, including but not limited to hydroxychloroquine, methotrexate, cyclosporin A, cyclophosphamide, tacrolimus, mycophenolate, tripterygium, and compound glycyrrhizin, within 30 days or 5 half-lives (whichever is older) prior to screening;
- • 11. The investigator determines that the subjects have any conditions that make them unfit to participate in the experiment (such as weak health, poor compliance, etc.).
