Number of Participants Experiencing Adverse Events
Up to 140 Days

An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product that does not necessarily have a causal relationship with the treatment.

Incidence of Study Drug-Related Grade 3 or Higher Adverse Events (AEs)
Up to Day 255

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug as either "Reasonable Possibility" or "No Reasonable Possibility" and will assess the severity of each adverse event from Grade 1 (mild) to Grade 4 (potentially life-threatening).

Frequently asked questions about Trosunilimab

What is trosunilimab?

Trosunilimab is an investigational antibody-based biologic being developed by AbbVie Inc. for Crohn's disease. It is in Phase 1 clinical development and has not been approved for any use. Its only listed clinical study to date is a Phase 1 trial in healthy adult volunteers.

What is trosunilimab used for in Crohn's disease?

Trosunilimab is being developed as a treatment for Crohn's disease, an inflammatory bowel condition. It is investigational and has not been approved for Crohn's disease or any other indication. The only trial listed for trosunilimab enrolled healthy volunteers rather than patients with Crohn's disease.

Who makes trosunilimab?

Trosunilimab is developed by AbbVie Inc., which trades on the New York Stock Exchange under the ticker ABBV. AbbVie is the sponsor of the drug's clinical program, which currently consists of a single Phase 1 study conducted in the United States.

What phase is trosunilimab in?

Trosunilimab is in Phase 1 clinical development. It is an investigational biologic and is not FDA approved. The program currently has one Phase 1 trial, which is recruiting, and no completed trials. That study is designed to enroll about 60 participants.

What clinical trials is trosunilimab in?

Trosunilimab is being studied in one Phase 1 trial, NCT07925983, titled a study to assess how intravenous and subcutaneous administrations of trosunilimab move through the body of healthy adult participants. The trial is recruiting in the United States, targets about 60 healthy volunteers aged 18 and older, and is active controlled and randomized.
