Summary

"This trial aims to see how a new drug, AZD4041, interacts with other drugs and how safe it is in healthy individuals. In addition, the study will also look at how effective and

Who is the study for?

This trial is for adults with moderate to severe opioid use disorder. Part 1 involves healthy participants to study drug interactions, while Part 2 focuses on those with OUD. Participants must not have other significant health issues that could interfere with the study.

What is being tested?

The trial has two parts: The first part tests how AZD4041 interacts with itraconazole in healthy people. The second part checks if AZD4041 is effective and safe when taken with buprenorphine or buprenorphine/naloxone by individuals with OUD.

What are the potential side effects?

Potential side effects may include typical reactions to opioids like drowsiness, constipation, nausea, and potential interaction effects from combining drugs such as increased sedation or respiratory issues.
