INDV-6001 Multiple-Dose Pharmacokinetic Study

Phase 2
Recruiting
Conditions
Moderate to Severe Opioid Use Disorder

Registration Number
NCT06576843
Lead Sponsor
Indivior Inc.
Brief Summary

This is a multicentre, open-label, multiple dose study of INDV-6001 in adult participants with moderate or severe OUD as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5).

The current study will evaluate the pharmacokinetics (PK), safety, and tolerability of INDV-6001 following multiple doses in participants with OUD to select optimum dosing regimens for future studies. Prior to receiving INDV-6001, participants will be stabilised on 12-16 mg of transmucosal (TM) BUP (SUBOXONE®) or will transition from a 100-mg monthly maintenance dose of SC extended-release BUP (SUBLOCADE®). This study will also evaluate the use of alternative injection sites (thigh, back of upper arm), which may be desirable in this patient population for the anticipated extended durations of treatment.

Detailed Description

Study Cohorts:

There are multiple cohorts (1, 2, 3, 4 and 7) testing varying dose strengths and frequencies of INDV-6001 in participants who are not receiving long-acting treatment for OUD. Up to 15 participants from each of the Cohorts 1, 2, 3, and 4 will enrol into Cohorts 1a, 2a, 3a, and 4a, respectively.

Study Periods:

Screening Period: from the Screening Visit until prior to the first SUBOXONE or SUBLOCADE dose as a part of this study Pre-Investigational Medicinal Product (IMP) Period: from the first SUBOXONE or SUBLOCADE dose as a part of this study until prior to the first INDV-6001 dose IMP Period: from the first INDV-6001 dose until the SUBLOCADE injection (Cohorts 3a and 4a only) or until the end of the study (EOS; all remaining cohorts) Post-IMP Period: (Cohorts 3a and 4a only) from the SUBLOCADE injection until EOS
