Buprenorphine Benefits Waitlisted Seekers of Opioid Treatment

March 24, 2017
By Eric Sarlin M.Ed. M.A., NIDA Notes Contributing Writer
  • In two pilot clinical trials, buprenorphine helped participants reduce their illicit opioid use and injection drug use while awaiting admission to a methadone or buprenorphine treatment program.
  • Researchers minimized the risks for improper use or diversion of the study medication by giving it to trial participants in a computerized, tamper-proof device that dispenses one dose each day.
  • Research staff monitored participants’ craving, withdrawal, drug use, and medication adherence with an interactive voice response system and random callbacks.

For most adults with opioid use disorder, maintenance therapy with methadone or buprenorphine is the most effective treatment approach. However, many who present to clinics offering such treatment are placed on waitlists for months. During this time, they are at high risk for continued drug use, overdose, death, criminal activity, infectious diseases, and other negative outcomes. Although studies have shown that interim methadone treatment can reduce drug use and associated risks during the waitlist period, regulatory and logistical challenges have hindered its wide implementation. Now, NIDA-supported researchers have developed an interim buprenorphine regimen and found it to be safe, effective, and potentially feasible in two small trials.

Dr. Stacey Sigmon and colleagues at the University of Vermont used technology to provide waitlisted opioid users with controlled access to buprenorphine and support their abstinence with minimal clinical and administrative input. After a week of daily clinic visits in which the trial participants were inducted onto buprenorphine and their dosing requirements determined, each was issued a Med-O-Wheel Secure dispensing device stocked with a 2-week supply of buprenorphine/naloxone sublingual tablets (see Figure 1). The tamper-proof device was programmed to make each day’s dose available during a 3-hour time window. Each evening, participants were contacted via a phone-based interactive voice response (IVR) system and prompted to rate their opioid cravings and withdrawal symptoms and to report any use of opioids or other drugs. Once every other week, at random times, the IVR system also notified participants to report to the clinic for urine drug testing and progress monitoring. Participants could also contact the research staff between visits if they experienced difficulties with craving, withdrawal, or other problems.

See text description Figure 2. Effects of Interim Buprenorphine on Abstinence From Illicit Opioids In the 12-week study, 50 participants were randomly assigned to buprenorphine or the control condition without buprenorphine. The data points show the proportion of patients who submitted illicit-opioid-free urine samples at intake and at 4-week intervals. Among the study participants randomly assigned to buprenorphine, 88 percent submitted illicit-opioid-free at week 4, 84 percent at week 8, and 68 percent at week 12. In contrast, none of the control participants submitted any illicit-opioid-free urine samples throughout the entire study.

Dr. Sigmon and colleagues first tested their approach in a feasibility trial with 10 participants who had been using opioids, on average, for 8.4 years. Most primarily used prescription opioids, although 60 percent reported having used heroin at least once. After being stabilized on buprenorphine, 90 percent of participants provided urine samples that were negative for illicit opioids at 2 and 4 weeks, and 60 percent were abstinent at 8, 10, and 12 weeks. Whereas the participants reported using opioids on 29 days, on average, in the month before starting the trial, the seven who completed the trial reported using the drugs an average of 0.35 days during its final month. The participants also registered lower scores on the Addiction Severity Index at the end of the study, compared with their scores at intake. Completion of the IVR calls and random callbacks were high at 97 and 82 percent, respectively.

See text description Figure 3. Effects of Interim Buprenorphine on Self-Reported Use of Illicit Opioids and Injection Opioids In the 12-week study, 50 participants were randomly assigned to buprenorphine or the control condition without buprenorphine. The bars represent the number of days on which participants in the two groups reported use of illicit opioids or intravenous opioids in the past 30 days at intake and at intervals of 4 weeks. After 4, 8, and 12 weeks, study participants taking buprenorphine reported significantly fewer days of illicit-opioid and intravenous opioid use compared with the control subjects.

In the subsequent larger trial, 25 waitlisted opioid-dependent adults were randomized to receive interim treatment with buprenorphine, and another 25 to remain in a waitlist control condition. Nearly 90 percent of the participants who received buprenorphine provided urine specimens that were free of illicit opioids at 4 and 8 weeks after induction, and nearly 70 percent at 12 weeks (see Figure 2). In contrast, no control participants provided illicit-opioid–negative specimens during the trial. The participants who received buprenorphine also reported significant reductions in frequency of illicit-opioid use and injection-opioid use, as well as in Addiction Severity Index scores (see Figure 3). Similar to the prior study, the patients who received buprenorphine responded to nearly all—96 percent—of both the IVR calls and the random callbacks.

Dr. Sigmon and colleagues will aim to replicate and extend these results in larger trials. Ultimately, they hope that their approach to helping treatment-seeking opioid users reduce risks while awaiting program admission will prove both beneficial and cost-effective.

These studies were supported by NIH grants DA037385, T32DA007242, and P20GM103644.

I reside in New England, &amp; have been participating for a number of years in a MAT program, using Buprenorphine to treat Chronic Pain, I'm also a Recovering Alcoholic whose Doctors were afraid of continued long term Opioid treatment.... Luckly I was directed to Suboxone Treatment, & Finaly to participation in a MAT Recovery Program, My Nagging Question is Always the Insurance Company's use of Prior Auth's to continue treatment, &, this is a Yearly Situation, with no end in site. Our Opiate Problem has negated a considerable group of people who through the use of Buprenorphine have reduced or completely stopped there use of other Narcotics, & are living & participating in the Community, but still having to deal with the Constant "Harasment from the Insurance Industry Through Prior Auth's ... There is little doubt in my mind that the General Public Knows very little about the Positive Productive Contributions made by those of us who have for what ever reason found Treatment For Chronic Pain with Buprenorphine, (MAT Recovery), from almost always a life of dependence on the more dangerous,& addictive Pain Medications, but as said eariler a common complaint is the use of "Prior Auth's" It seems that Education has failed to Recognize the Recovery that exists in the Community. Thank you, Kevin J. Waters Rhode Island

Hi I'm an addict for since for more than 20 yrs know and I wanted to say subboxone has helped me overcome alot since over the years. I found stability; I almost killed myself and my family in the mist of all my selfishness and pain. Since then I want to tapper off of the suboxone and never really thought about it twice because I have been happy and complacent where I am. Although know I would like to have a more prestige's job which requires me to not be on Suboxone and I feel like I have hit a brick wall again. So thinking about getting off is hard because it has been such a wonderful drug for me it has helped me stay away from harder drugs than itself however there is such a horible stigma on it . I have come so far in life. Tell you what I was supposed to graduate high school in 2000 but I did in 2004 and tried to become a Medical Assistant then since I was fired decided to go back to school in 2013 I'm going to graduate with a Criminal Justice admin degree and want to serve my community and others to help them in crises and particularly addiction. My dad was a addict and my mom so I want to show my kids that an addiction does not have to control your life. I hope you can answer me a question about suboxone if I tapper one week 16mg go down to 8mg then go down to 4mg and then 2mg in a month do you think it is possible and safe? I really want to get involved Ive never got to know myself or others without being on a drug and cant wait to learn how to love others as well. Do you think Suboxone will ruin my ability to do the job I want later???
