However, a subset of the most severely affected individuals do not benefit sufficiently from this treatment. The North American Opiate Medication Initiative (NAOMI) is a randomized clinical trial (RCT) to evaluate the hypothesis that pharmaceutical-grade heroin, diacetylmorphine (DAM) is more effective in retaining patients and improving their outcomes than Methadone Maintenance Treatment (MMT) among those with chronic, refractory injection opioid dependence.<\/jats:p>\n                  <jats:p>Purpose\/Methods The study aimed at randomizing 253 participants to two intervention arms: (1) MMT alone or (2) injectable opioids (DAM or hydromorphone) plus adjunctive MMT if deemed appropriate. The planned study duration was 3 years, with a 1-year intake period, 1 year of treatment, and an additional year of follow-up. The NAOMI trial was initiated in March 2005 at two Canadian sites (Vancouver and Montreal). This was the first multicenter RCT in North America to compare the relative efficacy of these different therapeutic strategies. We discuss the rationale behind the NAOMI study design, as well as the scientific and political issues and methodological challenges arising from the conduct of a trial that involves the prescription of a controlled substance to individuals with dependence on that substance.<\/jats:p>\n                  <jats:p>Limitations Restrictive entry criteria led to the exclusion of many otherwise eligible participants, slowing recruitment into the study. Inability to offer DAM treatment beyond 12 months led to artificial boundary effects in the trial. Conclusions Addiction treatment research navigates between science and politics, and evidence-based medicine is many times confronted by moral beliefs. Political considerations influence study design to a further degree than in RCTs treating less-stigmatized disorders with more-reputable medications.<\/jats:p>","DOI":"10.1177\/1740774509105222","type":"journal-article","created":{"date-parts":[[2009,6,15]],"date-time":"2009-06-15T06:48:33Z","timestamp":1245048513000},"page":"261-271","source":"Crossref","is-referenced-by-count":32,"title":["Scientific and political challenges in North America's first randomized controlled trial of heroin-assisted treatment for severe heroin addiction: Rationale and design of the NAOMI study"],"prefix":"10.1177","volume":"6","author":[{"given":"Eugenia","family":"Oviedo-Joekes","sequence":"first","affiliation":[{"name":"School of Population and Public Health, University of British Columbia, Vancouver, BC, Canada, , Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bohdan","family":"Nosyk","sequence":"additional","affiliation":[{"name":"Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David C","family":"Marsh","sequence":"additional","affiliation":[{"name":"School of Population and Public Health, University of British Columbia, Vancouver, BC, Canada, Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada, Department of Psychiatry, University of British Columbia, Vancouver, BC, Canada, Vancouver Coastal Health, Vancouver, BC, Canada, Providence Health Care, Vancouver, BC, Canada, Centre for Addiction Research British Columbia, Victoria, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daphne","family":"Guh","sequence":"additional","affiliation":[{"name":"Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suzanne","family":"Brissette","sequence":"additional","affiliation":[{"name":"Centre de recherche du l'Universit\u00e9 de Montr\u00e9al, Montreal, QB, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Candice","family":"Gartry","sequence":"additional","affiliation":[{"name":"CIHR Canadian HIV Trials Network"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Krausz","sequence":"additional","affiliation":[{"name":"Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada, Department of Psychiatry, University of British Columbia, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aslam","family":"Anis","sequence":"additional","affiliation":[{"name":"School of Population and Public Health, University of British Columbia, Vancouver, BC, Canada, Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin T","family":"Schechter","sequence":"additional","affiliation":[{"name":"School of Population and Public Health, University of British Columbia, Vancouver, BC, Canada, Centre for Health Evaluation & Outcome Sciences, Providence Health Care, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,6,15]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1177\/0193841X07307315"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1006\/nlme.2002.4099"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/j.coph.2004.08.012"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwg209"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1159\/000088581"},{"key":"atypb6","first-page":"CD002209","author":"Mattick RP","year":"2003","journal-title":"Cochrane Database Syst Rev"},{"key":"atypb7","doi-asserted-by":"crossref","unstructured":"Amato L, Davoli M, A Perucci C, et al.
