Official title

A Phase 1 Study to Evaluate the Effect of Multiple IV Infusions of Risankizumab on the Pharmacokinetics of Cytochrome P450 Substrates Administered Orally in Subjects With Moderately to Severely Active Ulcerative Colitis or Crohn's Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
