ClinConnect Summary

This clinical trial is looking at a new treatment called INDV-2000 for people with moderate to severe opioid use disorder (OUD). The goal is to see how safe and effective this treatment is, as well as to find the right dose that works best. The study is for individuals who have recently started or finished a medically supervised withdrawal from opioids and are interested in moving to a non-opioid treatment option.

To participate, individuals must be between 18 and 65 years old and have a diagnosis of moderate to severe OUD. They should also be in the process of withdrawing from opioids or have completed withdrawal recently. Participants will need to agree to follow the study guidelines and attend all scheduled visits. Throughout the trial, they can expect to receive the new treatment and be monitored closely for their safety and response to the medication. It’s important to note that certain medical conditions or recent substance use may disqualify individuals from participating.
