This is an interventional treatment trial for Urticaria

Eligibility Criteria

18 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Aged 18-75 years, inclusive
  • Diagnosis of chronic spontaneous urticaria (CSU) refractory to H1 antihistamines at the time of randomization
  • Willing and able to complete an Urticaria Participant Daily eDiary for the duration of the study
  • No evidence of active or latent or inadequately treated infection with tuberculosis (TB)

  • Only for participants currently receiving proton-pump inhibitors (PPIs) or H2 receptor antagonists (H2RAs): Treatment must be at a stable dose during the 2-week screening period prior to randomization and with a plan to remain at a stable dose for the duration of the study
  • For women of childbearing potential: Agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of <1% per year during the treatment period and for at least 4 weeks after the last dose of study drug. Women must refrain from donating eggs during this same period.

Exclusion Criteria:

  • Treatment with omalizumab or other monoclonal antibody therapies used to treat CSU within 4 months prior to screening or primary nonresponse to omalizumab
  • Use of a non-biologic investigational drug or participation in an investigational study with a non-biologic drug within 30 days prior to study drug administration on Day 1 (or within 5 half-lives of the investigational product, whichever is greater)
  • Use of a biologic investigational therapy or participation in an investigational study involving biologic therapy within 90 days or 5 half-lives, whichever is greater, prior to study drug administration on Day 1
  • Previous treatment with GDC-0853 or other Bruton's tyrosine kinase (BTK) inhibitors
  • Participants whose urticaria is solely due to physical urticaria
  • Other diseases with symptoms of urticaria or angioedema, including urticarial vasculitis, urticaria pigmentosa, erythema multiforme, mastocytosis, hereditary or acquired angioedema, lymphoma, or leukemia
  • Atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, or other skin disease associated with itch such as psoriasis
  • Routine doses of the following medications within 30 days prior to screening: systemic or cutaneous (topical) corticosteroids (prescription or over the counter), hydroxychloroquine, methotrexate, cyclosporine, or cyclophosphamide
  • Prior utilization of intravenous (IV) steroids for treatment of laryngeal angioedema
  • Intravenous immunoglobulin G (IV IG) or plasmapheresis within 30 days prior to screening
  • History of anaphylactic shock without clearly identifiable avoidable antigen
  • Hypersensitivity to GDC-0853 or any component of the formulation
  • Major surgery within 8 weeks prior to screening or surgery planned prior to end of study (12 weeks after randomization)
  • Require any prohibited concomitant medications
  • History of live attenuated vaccine within 6 weeks prior to randomization or requirement to receive these vaccinations at any time during study drug treatment
  • Evidence of clinically significant cardiac, neurologic, psychiatric, pulmonary, renal, hepatic, endocrine, metabolic, or gastrointestinal (GI) disease that, in the investigator's opinion, would compromise the safety of the participant, interfere with the interpretation of the study results or otherwise preclude participant participation
  • Current treatment with astemizole, terfenadine, and/or ebastine
  • Uncontrolled disease states, such as asthma, psoriasis, or inflammatory bowel disease, where flares are commonly treated with oral or parenteral corticosteroids

Outcomes

Primary Outcome Measures

Change From Baseline in the Urticaria Activity Score Over 7 Days (UAS7) at Day 57
The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. The maximum UAS7 value is 42. A higher score indicates worse disease. A negative change score (Day 57 score minus Baseline score) indicates improvement.

Secondary Outcome Measures

Percentage of Participants Who Are Well-Controlled (UAS7 ≤ 6)
The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. The maximum UAS7 value is 42. A higher score indicates worse disease. Participants with UAS7 score ≤6 are considered well controlled.
Change From Baseline in the UAS7 at Day 29
The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. The maximum UAS7 value is 42. A higher score indicates worse disease. A negative change score (Day 29 score minus Baseline score) indicates improvement.
Percentage of Participants With Adverse Events (AEs)
An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An Adverse Event can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as Adverse Events.
Plasma Concentrations of Fenebrutinib (GDC-0853) at Specified Timepoints
Plasma Concentration Data for fenebrutinib (GDC-0853) will be tabulated and summarised by visits. Descriptive summary statistics for Arithmetic Mean and Standard Deviation will be presented. Please note that the Placebo Cohorts were not evaluated for this Outcome Measure.
