This is a randomized, double-blind, multicenter Phase IIIb study comparing remibrutinib tablets with dupilumab injections in adults with chronic spontaneous urticaria (CSU) that is not well controlled by second-generation H1-antihistamines. Participants will receive either remibrutinib or dupilumab for 12 weeks, alongside their usual antihistamine. The goal is to see which treatment works faster and better at reducing symptoms like hives and itching. If remibrutinib is not yet available commercially after the study, participants may continue taking it in an optional extension phase.

The purpose of this study is evaluate safety and effectiveness of an investigational drug in adults diagnosed with chronic urticaria (hives). The investigational drug is known as BLU-808 and will be taken daily orally. Participation in the study is expected to be approximately 18 weeks.

This is a randomized, double-blind, multicenter, parallel-group Phase IIIb study with a fixed treatment period of 52 weeks. The purpose of this study is to compare BDA MDI with AS MDI on severe asthma exacerbations in adolescent participants aged 12 to < 18 years with a documented clinical diagnosis of asthma and at least one severe exacerbation in the prior year. Participants will administer randomized IMP as needed as they normally would with their own prescribed rescue inhaler.

The purpose of this study is determine the optimal dose, efficacy and safety of an investigational drug (a new drug not yet approved by the U.S. Food and Drug Administration) in adults with Advanced Systemic Mastocytosis. The investigational drug is known as CGT9486 and will be taken daily orally. Participation in the study is expected to be approximately 6 years.

The purpose of this study is to see if taking depemokimab is safe and effective in treating Hypereosinophilic syndrome (HES) in adults (≥18 years) with uncontrolled HES receiving standard of care (SoC) therapy. The study will last approximately 52 weeks and is a placebo-controlled, double blind, multicentre study.
