A Study to Evaluate the Effect of Intravenous (IV) Infusions of Risankizumab on Pharmacokinetics of Cytochome P450 Substrates in Adult Participants With Moderately to Severely Active Ulcerative Colitis or Crohn's Disease

Completed · Phase 1

Conditions studied: Ulcerative Colitis (UC), Crohn's Disease

In brief

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine).Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. CD may cause tiredness, loose stools with or without bleeding, abdominal pain, weight loss, and fever. This study will evaluate the effect of repeated infusions of risankizumab on the pharmacokinetics of sensitive probe substrates of Cytochrome P450 (CYP) enzymes in participants with moderately to severely active UC or CD. Risankizumab is an investigational drug being developed to treat trial participants with inflammatory diseases such as UC and CD. The study is split into two periods. In Period 1, participants will receive single oral doses of CYP sensitive probes and in Period 2, participants will receive risankizumab followed by single oral doses of CYP sensitive probes. Around 20 adult participants with moderately to severely active CD or UC will be enrolled in the study across multiple sites worldwide. In Period 1, participants will receive oral doses of CYP sensitive probes on Day 1. In Period 2, participants will receive risankizumab by intravenous (IV) infusion on Days 1, 29 and 57 followed by oral CYP sensitive probes on Day 64. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests and checking for side effects.

You may qualify if…

Confirmed diagnosis of UC or CD for at least 3 months prior to Day -1 (baseline). Appropriate documentation of biopsy results consistent with the diagnosis of CD or UC, in the assessment of the gastroenterologist, must be available.
Moderately to severely active CD or UC.
Must have demonstrated intolerance or inadequate response to one or more of the following categories of drugs: aminosalicylates, oral locally acting steroids, systemic steroids, immunomodulators, and/or approved biologic therapies.
Participant must agree to not use any known inhibitors or inducers of cytochrome P450 within 1 month or 5 half-lives, whichever is greater before each administration of the cocktail probe and until the last pharmacokinetic sample is collected, 7 days after the intake of each probe cocktail.

You may not qualify if…
