Description
Inclusion Criteria:
To be eligible to participate in the study, individuals must meet all the following inclusion criteria at Screening (and at other timepoints, where specified):
Male or female aged ≥18 and ≤59 years. Body mass index of ≥18 kg/m2 and ≤33 kg/m2. Moderate or severe OUD according to the DSM-5 criteria. Clinically stable (for at least 6 months) on oral daily methadone therapy at a dose of 80 to 100 mg and have been taking the same dose for at least 3 months, and are stably engaged in a methadone program, confirmed by a methadone provider and defined as (1) demonstrates evidence of regular attendance, (2) has not had problems with missed visits, and (3) consistently demonstrates drug-negative urine samples (except for cannabis).
Agree to provide the study site with contact information for the clinic where they get methadone and agree that a study physician can contact the clinician providing methadone to confirm appropriateness for study participation and to manage their transition into the study and from the study back to their opioid treatment program.
Able to read and understand study procedures and provide written informed consent before the initiation of any protocol-specific procedures.
Willing to comply with all protocol-specified procedures and availability for the duration of the study (e.g., participant is not aware of any emergent life-changes or potential family emergencies that would interfere with a 40+ day inpatient stay).
Exclusion Criteria:
