Cohort B enrols nonrandomly through a separate recent-use ibogaine pathway with matching intramuscular placebo.

Outcome assessors, cardiac adjudicators and the study statistician are masked where feasible under the blinding plan. Treatment guesses are recorded to assess functional unblinding. Emergency unblinding is permitted when needed for participant care.","1 Purpose and design This funding- and authorisation-dependent study has three parallel cohorts. A and C constitute the randomised comparison of XR-naltrexone and ibogaine using matching oral and intramuscular placebos. B is a separate recent-use cohort and is analysed separately. The study evaluates acute safety, cardiac effects, eligible acute-withdrawal outcomes, feasibility and preliminary recovery outcomes during equivalent 12-month support. It does not include a placebo-only cohort deprived of continuing addiction care.\n\n5 Study Description continued\n\n2 Screening and baseline Potential participants undergo confirmation of DSM-5-TR moderate or severe opioid use disorder, consent capacity, treatment need and cohort eligibility. Screening includes medical and psychiatric history, physical and neurological examination, suicide and self-harm assessment, medicine and supplement reconciliation, recent-substance assessment, safety laboratory tests, pregnancy testing where applicable and specialist cardiovascular evaluation. Cardiac screening includes qualifying 12-lead ECGs, electrolytes and personal and family arrhythmia history, with further investigations where indicated.\n\nThe study provides a Garmin Venu 4, an Apple phone, training, connectivity and accessibility support. A 14-28-day digital baseline is sought where feasible without delaying clinically necessary care; shorter baselines and reasons are recorded. Baseline digital information includes participant-reported mood, craving, withdrawal, sleep, adherence and engagement, together with wearable-derived longitudinal wellness measures. Interpretation emphasises change within the participant. Minimum evaluable baseline coverage is specified in the data plan.\n\n3 Cohort assignment and treatment transition Participants entering A\u002FC complete the approved opioid-free interval and negative naloxone challenge before randomisation and assigned treatment. Randomisation is 1:1; the proposed opioid-free strata of 7-29 versus at least 30 days require confirmation. The safe interval depends on the opioid, treatment history and specialist assessment; the strata do not replace eligibility requirements.\n\nCohort B uses the approved recent-use pathway without a universal 30-day abstinence requirement. The planning model permits up to 48 hours of first-admission stabilisation. Current methadone treatment does not permit direct entry to B. Previous methadone or buprenorphine exposure is not a lifetime exclusion, but a protocol-approved specialist transition must be completed before dosing. Abrupt or unsupervised discontinuation of effective treatment is not required to enter the trial.\n\n4 Monitored treatment admissions Three oral-treatment sessions occur at Months 0, 1 and 2. A receives matching oral placebo and B\u002FC receive pharmaceutical-quality ibogaine hydrochloride. Formulation, dose, weight cap, timing, prohibited medicines, interaction controls, residual-noribogaine criteria and repeat-dose release conditions require final clinical and regulatory agreement. No numerical ibogaine dose is specified by this registration consolidation.\n\nAll cohorts receive equivalent clinical observation and supportive care. The shared planning model retains continuous telemetry for the 72-hour post-dose window, serial clinically interpreted 12-lead ECGs, vital signs, safety laboratory testing and pharmacokinetic sampling where applicable. Monitoring continues beyond the scheduled window when clinically required. Resuscitation capability, cardiology and emergency support, and a documented transfer pathway must be operational before site activation.\n\nThe protocol monitors cardiovascular, neurological and psychiatric adverse events, including dehydration, vomiting, aspiration, ataxia, falls, seizures, agitation, mania, psychosis and suicidality. Clinically relevant abnormalities require assessment and correction. QTcF of at least 500 ms or an increase of at least 60 ms enters the proposed stopping pathway; the confirmed measurement, action and cohort-pause rules must appear in the controlled clinical protocol. Consumer wearables are not used to measure QTc or to replace telemetry or 12-lead ECGs.\n\n5 Study Description continued\n\n5 Continuing care and injections The planned schedule comprises twelve calendar-monthly IM injections at Months 0-11: XR-naltrexone 380 mg in A and matching placebo in B\u002FC. The first three injections occur during the corresponding monitored admissions when medically appropriate. The first-injection reference date, exact visit windows, eligibility, missed-dose management and rescue rules require D5 confirmation. No study injection is scheduled at Month 12.\n\nAll cohorts attend monthly clinical visits through Month 12 for review, ECG, protocol-defined laboratory testing, toxicology, recovery planning and face-to-face support. Naloxone challenge is performed only when required by the approved A\u002FC pathway and clinical circumstances; it is not automatically repeated at every monthly visit. Weekly online integration continues through Month 3, with continuing clinical support throughout follow-up.\n\nBefore discharge, participants receive an individual continuing-care and overdose-prevention plan, naloxone access and education, information about reduced opioid tolerance, rapid access to opioid agonist treatment when indicated or requested, psychiatric and addiction referrals, emergency contacts and relevant social support. Rescue care and transition to ordinary treatment are not withheld to preserve study allocation. Follow-up continues after treatment discontinuation when consent permits.\n\n6 Digital support and participant assessments Daily participant check-ins and Garmin-derived wellness data feed SENTINEL outside scheduled acute-admission pauses. Clinical monitoring continues during these pauses. PHQ-9 and GAD-7 are collected weekly through Month 12. EFP Mini, PCL-5 and the selected quality-of-life instrument are collected monthly, with registered change analyses at Months 1, 3, 6 and 12. SOWS and OOWS follow the acute schedule and are collected weekly through Month 3, then monthly during Months 4-12. Craving measurement and all instrument-specific rules require the decisions identified in Appendix C.\n\nThe five-state model comprises Green, Yellow, Orange, Red and Urgent. Orange requires same-day qualified clinical review; Red requires immediate live contact and urgent evaluation; Urgent directs immediate emergency action. Exact operational response windows, staffing, backup and coverage require the approved escalation SOP. Medical emergencies are directed to 911; 988 may support suicide or crisis needs without delaying emergency response. Students may support Green\u002FYellow activities under supervision and must not independently close Orange or higher events. SENTINEL does not autonomously diagnose, prescribe or change medication.\n\n7 Trial data and regulatory status The validated study electronic data capture system remains the trial data system of record. Source records, ECGs, laboratory results, adverse events, protocol deviations and investigational-product accountability remain within the sponsor-approved architecture. SENTINEL supplies governed data transfers, audit trails, recorded human actions and longitudinal support. The study will report results by cohort, account for missingness and rescue treatment, and avoid treating the nonrandomised B cohort as part of the randomised A\u002FC comparison.\n\nThe IND application has not yet been filed. The study remains not yet recruiting. ClinicalTrials.gov registration and assignment of an NCT number do not authorise study conduct.

Uncorrected hypokalaemia, hypomagnesaemia, hypocalcaemia, or another clinically significant electrolyte or acid-base abnormality.\n7. Clinically significant hepatic impairment, decompensated liver disease, acute hepatitis, impaired hepatic synthetic function, or laboratory abnormalities expected to alter ibogaine or noribogaine exposure materially.\n8. Clinically significant renal impairment or unstable renal disease.\n9. Unstable respiratory, neurological, endocrine, gastrointestinal, haematological, infectious, or other systemic disease that could increase the risk of treatment, aspiration, arrhythmia, vomiting, immobility, or emergency intervention.\n10. Current sepsis, uncontrolled systemic infection, active infective endocarditis, or another infection requiring urgent treatment.\n11. Current pregnancy, intended pregnancy during the protocol-defined risk period, or breastfeeding.\n12. Known hypersensitivity or previous serious adverse reaction to ibogaine, noribogaine, another iboga alkaloid, or an investigational-product excipient.\n13. Previous ibogaine exposure associated with clinically significant QT prolongation, arrhythmia, syncope, seizure, mania, psychosis, cardiac arrest, or another serious adverse event.\n14. Use of a medication, supplement, or substance that creates unacceptable risk through one or more of the following: QT prolongation or torsade de pointes; Bradycardia or conduction disturbance; Clinically significant cytochrome P450 2D6 inhibition or induction; Serotonergic toxicity; Reduction of the seizure threshold; Excessive sedation or respiratory depression; Hemodynamic instability.\n15.

Recent cocaine, methamphetamine, amphetamine, 3,4-methylenedioxymethamphetamine, or another stimulant exposure within the protocol-defined safety period, or a pre-dose toxicology finding considered to create unacceptable cardiovascular risk.\n18. Current alcohol, benzodiazepine, barbiturate, or other sedative-hypnotic dependence requiring separate withdrawal management, or current risk of alcohol- or sedative-withdrawal seizure or delirium.\n19. Severe uncontrolled polysubstance dependence requiring simultaneous medical detoxification or preventing interpretable safety assessment.\n20. Current intoxication, delirium, severe uncontrolled withdrawal, or another condition preventing valid informed consent or safe study procedures.\n21. History of epilepsy, an unprovoked seizure, a clinically significant seizure disorder, or a recent withdrawal-related seizure, unless specifically reviewed and accepted under the FDA-authorised protocol.\n22. Current psychotic disorder, active psychotic symptoms, schizophrenia-spectrum disorder, or current substance-induced psychosis.\n23. Current manic or hypomanic episode, uncontrolled bipolar I disorder, or previous ibogaine- or psychedelic-associated mania.\n24.
