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.

Dystonia is a movement disorder that causes muscles to contract and/or spasm. This may be painful and can affect the person's ability to complete daily tasks. Dystonia may affect one or multiple parts of the body. Botulinum toxins (BoNT) are the only approved drug in the United States to treat dystonia, and this is only for dystonia of the neck or the eye. There are currently no approved oral treatments for dystonia. Most current treatments only provide relief of symptoms.
The purpose of this study is to learn about the effects of the research drug (VIM0423), to find the best dose for treating dystonia, and to see how safe VIM0423 is for patients with dystonia.
This research study is studying VIM0423 as a possible treatment for dystonia. It is being developed to be a combination dose of: VMA-1001 given with VMA-1002.
• VMA-1001 and VMA-1002 will be taken in separate oral doses at the same time.
• VMA-1001 is an extended release (ER) modified version of trihexyphenidyl (THP).
• VMA-1002 is a formulation of bethanechol (BTC).
THP and BTC are medicines approved by the U.S. Food and Drug Administration (FDA); however, the Sponsor is investigating a different formulation of THP referred to as VMA-1001 and a different formulation of BTC referred to as VMA-1002. The purpose is to attempt to minimize some side effects of THP and is therefore considered an investigational drug in this study. An investigational use is one that is not approved by the FDA.
You may be in this study for up to 32 weeks from the time you consent until the last study visit.
You will be seen at the study site 6 times (Screening, Day 1, Day 30, Day 60, Day 95, and Day 125) and will complete 4 telephone calls (Day 6, Day 13, Day 20 and Day 105). You may be asked to come for extra visits at any time during the study if the study doctor decides that extra tests are needed for your safety.
Side effects associated with the study drug are dry mouth, dry eyes, blurred vision, dizziness, mild nausea and feeling nervous.
You do not need to take part in this study to receive treatment for your isolated dystonia. The study doctor will explain other options that are available to you. Your other choices may include treatment with other medicines for isolated dystonia, another investigational treatment, treatment that makes you feel more comfortable but will not have an effect on your isolated dystonia, or no treatment.

Epidermolysis Bullosa (EB) is a rare, inherited skin condition that makes the skin extremely fragile, causing painful blisters and wounds from even minor friction or injury. There is currently no cure, and because EB is uncommon, doctors still have limited high-quality data to guide the best treatment and long-term care. This study is part of a large North American effort to collect and organize health information from people with EB into a secure database. By tracking how the disease progresses over time, along with symptoms, complications, and treatments, researchers hope to better understand EB and improve care for future patients. Participation involves consenting to share medical record information and optionally completing brief questionnaires during routine clinic visits or by email. No experimental treatments or extra medical procedures are involved. While there is no direct benefit to participants, the knowledge gained may help improve care and support the development of new treatments in the future.
