Remission & chronicity

Spontaneous remission

Spontaneous recovery (without MOUD) in 20-30% of OUD patients over 10 years; but overdose mortality risk during active disorder is extreme (5-10 per 1000 person-years); relapse rate 90%+ in first year after discontinuing MOUD

Best-intervention remission

Buprenorphine maintenance: 50-70% retention in treatment at 1 year vs <20% for placebo; naltrexone extended-release (Vivitrol): comparable to buprenorphine when initiated; methadone: superior retention but restricted distribution; overdose mortality reduced 50-70% with any MOUD

Gap size

Very large — only 20% of people with OUD receive MOUD; massive unmet need

Primary barrier

access/policy

Barrier detail: US eliminated the DEA X-waiver requirement for buprenorphine prescribing in December 2022 (a major policy win) but prescribing rates have increased slowly; stigma remains; methadone access restricted to OTPs (clinics); harm reduction infrastructure (fentanyl test strips, naloxone) still insufficiently deployed; 80% of people with OUD receive no treatment

Last SoC change: 2023 — DEA X-waiver elimination fully implemented; 2022 federal legislation allowing take-home methadone expanded; 2021 FDA approved injectable buprenorphine (Sublocade) for once-monthly dosing; buprenorphine SL since 2002; methadone for OUD since 1964

Right to Try Relevance

Eligibility: This disease meets the federal and state right-to-try legal standard (21 U.S.C. § 360bbb-0a and Montana SB 535): it lacks disease-modifying therapy with indication-specific FDA approval. Patients with Opioid Use Disorder may be eligible to access investigational therapies outside of clinical trials under right-to-try frameworks.

Legal Standard: Right-to-try requires the disease lacks "adequate approved therapy for that specific disease" (not symptom-management drugs). This distinction means a disease with antidepressants available still qualifies if no FDA approval exists for THAT disease indication.
