INDV-6001 Multiple-Dose Pharmacokinetic Study

Completed · Phase 2

Conditions studied: Moderate to Severe Opioid Use Disorder

In brief

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.

• Has a concurrent primary substance use disorder, as defined by DSM-5 criteria, other than opioid, tobacco, cannabis, or mild to moderate alcohol use disorders
• Has an injection area unsuitable for SC injections (eg, nodules, scarring, lesions, excessive pigment) in the areas designated for possible injection in the study
• Is currently using another MOUD treatment other than TM BUP (eg, SUBOXONE) or has had prior treatment with any long-acting injectable form of a BUP-containing product in the past 18 months (or if 18-24 months with a positive UDS) prior to consent; treatment with oral naltrexone or methadone products within 14 days prior to consent (or positive UDS for methadone at Screening); or treatment with depot naltrexone within the 3 months prior to consent
