New Node Coordinator for the Appalachian Node: The Appalachian Node is excited to welcome Ellen Kline (ellenkline@pitt.edu) as our Node Coordinator. The Brief Report for CTN-0135 has been published: Winstanley EL, Leibschutz JM, Murray-Krezan C, Switzer GE, Nash S, Kawasaki S. Brief Report: Meth, Tranq, Gas Station Heroin & Other Drugs Complicating Addiction Treatment. American Journal on the Addictions 2026, 1-4. DOI: 10.1111/ajad.70151. The report describes the results of a single survey item from a national survey (n=396) that was conducted for CTN-0135 using a random sample of clinicians waivered to prescribe buprenorphine in the U.S. The item collected information about clinicians’ perceptions of other drugs, besides illicitly manufactured fentanyl, complicating treatment. Clinicians reported methamphetamine (86.4%), synthetic cannabinoids (42.7%), and xylazine (41.4%) were complicating treatment. Reports varied by geographic region. The study demonstrates that rapid clinician surveys can provide real-time data on changing patterns of drug use’s impact on treatment outcomes. Posted on March 17, 2026

CTN-0107, the Peer Intervention to Link Overdose Survivors to Treatment (PILOT) trial, is a 3-site, randomized controlled trial using Peer Recovery Coaches trained in FORCE (FAVOR Overdose Recovery Coaching Evaluation), who will engage with opioid overdose survivors in the emergency department to get permission to contact them. The protocol team recently submitted the PILOT manual used by peers working on the study for inclusion in the CTN Dissemination Library. The manual provides materials to be used during peer training, reference materials to be used during the implementation of the clinical trial, and reference material for supervision. At the end of the study, the manual will be revised with input from participating peers and a revised manual will be developed for use in any follow-up studies. The manual contains sections on the background of the PILOT study and intervention, what PILOT peers do in the study (engagement/re-engagement, peer coaching, transition and termination of the intervention), other things peers know and do in the PILOT study (study documentation, supervision, self-care and support, safety), and an array of tools and FAQs for peer participants. Check out the PILOT manual here! Posted on June 30, 2025.
