  1. Using Buprenorphine in Opioid Treatment Programs Allan J. Cohen MA, MFT Director of Research and Training Bay Area Addiction Research and Treatment, Inc. (BAART) American Association for the Treatment of Opioid Dependence Atlanta, GA April, 2006

  2. Assumptions Many of you are treatment providers primarily Most have at least heard of bup Few have seen it Differing degrees of exposure to and experience with bup Different local conditions do affect thinking and attitudes

  3. Bay Area Addiction, Research and Treatment (BAART) In operation for 30 years 14 treatment programs (12/2) 5,000 + patients in treatment Evidence-based treatment philosophy Participates in the NIDA CTN

  4. New CTN “START” Study Hepatic Safety Study Interested in gaining more experience with bup Wider exposure with immediate community Interested to see if bup has “curb” appeal? How will staff respond?

  5. Subutex® and Suboxone® • Two, schedule III, sublingual buprenorphine tablet formulations (2 mg and 8 mg) approved for US use: • Subutex® (buprenorphine alone) • Suboxone® (buprenorphine + naloxone) • In contrast, methadone is a schedule II drug • Partial mu-opioid agonists • Suboxone® is the focus of US marketing efforts

  6. “Methadone is the Gold Standard for treatment of chronic heroin addiction”

  7. Buprenorphine is not a substitute for methadone, it is one more choice on the treatment menu.Both are medications which should be used in comprehensive treatment

  8. Buprenorphine in the OTP(a natural and logical venue) Many years of experience treating opioid addictions All have medical coverage All have experience with medication assisted treatment All have counseling as key component in treatment Ancillary services available

  9. Consensus Panel 2003 Recommends counseling for patients receiving bup Counselors in OTPs should receive information and training about bup Concurrent counseling and support services are necessary OTP is preferable for patients needing “higher intensity” treatment

  10. Some Specific Treatment Provider Concerns Treatment need far exceeds utilization Educating staff and patients about buprenorphine Addressing 40 years of methadone success Finding “best fit” model for using bup Regulatory issues Cost issues Dispensing logistics

  11. cont’d We have very few alternatives – LAAM is dead, Naltrexone was stillborn What if OTP does not embrace and integrate buprenorphine? perceptions accessibility revenue

  12. Regulatory Issues DATA 2000 – physicians can use schedule III, IV, V meds in other than OTPs Suboxone and Subutex approved FDA 2002– approved for the treatment of opioid dependence Interim Final Rule 2003 – approval to use Suboxone/Subutex in OTP

  13. Interim Final Rule Use of Suboxone/Subutex must adhere to the same Federal standards as for methadone… (42 C.F.R. 8) State standards may supercede Cannot prescribe only dispense “Take Home” dosing as with methadone 30 patient limit does not apply

  14. Survey of 414 MMT Patient’s Interest in Switching to Buprenorphine • MMT patients at three OTPs surveyed • Los Angeles (BAART) • Detroit (JARC) • Baltimore (Univ. of Maryland) • Inquired about general knowledge of, and interest in, buprenorphine • Patients told to assume no cost differential

  15. Survey of 414 MMT Patient’s Interest in Switching to Buprenorphine % Who had heard about BUP Interest if had heard about BUP Interest if had not heard about BUP Overall interest

  16. Survey of 414 MMT Patient’s Interest in Switching to Buprenorphine Top reasons for wanting to switch to buprenorphine among patients expressing interest† • Good for medically-supervised withdrawal • Can be taken on 3x per week basis †option for OBOT not listed among choices

  17. Need: Demand: Utilization There are 1,110+ licensed OTPs in US 225,000+ patients in methadone maintenance tx 1,000,000 persons addicted to heroin 4.7 million current users of prescription opioids for non-medical purposes about 1.5 million dependent on or abusing pain rx Treatment admissions for new users increasing

  18. Need vs. Utilization

  19. Treatment Admissions

  20. Phases of Buprenorphine Treatment • Dose induction and stabilization • Maintenance • Medically-supervised withdrawal

  21. Rapid and direct dose induction:short-acting opioids • Patients taking short-acting opioids (e.g., heroin) can be placed directly on Suboxone® • Most patients complete induction and can achieve a stable dose of medication within 7days • Induction should be rapid and doses adjusted to clinical need as quickly as possible to reduce withdrawal and craving and prevent early drop-out

  22. Induction from Long-Acting Opioids (methadone) • More controlled data are needed to determine optimal strategies for Crossover • Current US guidelines recommend lowering dose to the equivalent of about 40 mg of methadone before attempting to transfer • Physicians should not necessarily refuse to treat patients on higher doses of methadone or require a substantial lowering of their current medication dose before attempting transfer

  23. Phases of Buprenorphine Treatment • Dose induction and stabilization • Maintenance • Medically-supervised withdrawal

  24. Buprenorphine, Methadone, LAAM:Opioid-Negative Urine Results 100 All Subjects 80 LAAM 49% 60 Bup 40% Hi Meth Mean % Negative 40 39% Lo Meth 20 19% 0 1 3 5 7 9 11 13 15 17 Study Week Johnson et al. (2000)

  25. Buprenorphine, Methadone, LAAM: Treatment Retention 100 73% Hi Meth 80 60 58% Bup Percent Retained 53% LAAM 40 20 20% Lo Meth 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 Study Week Johnson et al. (2000)

  26. Maintenance Considerations • We should consider buprenorphine as a maintenance drug • More information would be helpful • Regulations must be brought into alignment with clinical opportunity • Flexibility of dosing: 3X/wk dosing

  27. Phases of Buprenorphine Treatment • Dose induction and stabilization • Maintenance • Medically Supervised Withdrawal

  28. Medically supervised withdrawal • Good agent for pharmacologic withdrawal from opioids • slow dissociation from receptor, extended duration of action, less/milder withdrawal when discontinued • Research more limited in this area but we do know: • Subutex®/Suboxone® better than clonidine • Ancillary medications should be made available but not always necessary • May help attract more patients into treatment

  29. Effective Medically Supervised Withdrawal should: • Be the initial step in a treatment continuum • Safely control symptoms of withdrawal • Engage patients through out the actual withdrawal insuring completion • Facilitate their transfer into long term treatment

  30. Medically supervised withdrawal: summary • Short-term supervised withdrawal using Suboxone® and ancillary medications is safe, can maintain good during-treatment compliance and retain patients through the end of the dose taper • Such programs may improve early treatment engagement among patients resistant to maintenance therapy and may provide a gateway to longer-term care • May be a good first-line option for younger users, those with limited treatment histories and/or patients who initially refuse maintenance therapy

  31. Evidence support: Summary • Safe, well-tolerated, effective and clinically flexible treatment with low abuse potential • Good option for maintenance and medically supervised withdrawal • Easily integrated into diverse settings (OTP, office, hospital, residential, drug-free, etc.) • Potential for enhancing management of special populations • As knowledge about buprenorphine expands within OTPs, patient interest also likely to increase

  32. Training/Education OTP staff are knowledgeable about methadone treatment Ongoing training in OTP is mandatory Staff understanding regarding bup varies enormously Three levels of educational need: Medical Counselors Patient

  33. Training cont’d Numerous physician trainings – various professional organizations ATTC non-physician clinician courses New Treatment Improvement Protocol (TIP) #40 NIDA & CSAT/SAMHSA Websites Online Courses

  34. http://www.danyalearningcenter.org CEATTC Website Online Buprenorphine Training Course for Counselors

  35. Education is only a first step: Diffusion of innovation requires a champion and opinion makersEverett Rogers

  36. Some possible models Use under current OTP license Operation Par, FL Use under program physician DEA waiver 14th St, Oakland Bup “induction centers” Kleber, NY Bup “clinic” in OTP Satellite Centers “Hub and Spoke”

  37. Attractive and Interesting Offers providers an alternative May be attractive to specific populations Offers 3X/week dosing Does not carry “stigma” May offer more comfortable taper

  38. On the other hand….

  39. Old Adage The proverbial…”elephant sitting in the middle of the living room but…”

  40. $ Cost $

  41. Treatment Provider Cost Issues Current price for bup 8mg tab $4.50 2mg tab $2.50 Average dose 12 – 16mg/day Estimated monthly cost for 16mg/day = $270.00 meds only Who’s going to pay?

  42. Cost cont’d Not on all State Medicaid formularies Even where it is may be difficulties Some HMO’s “Kaiser” are paying Some insurance plans are paying TAR (treatment authorization request) Contracts - “bundled rates” Cash/self-pay

  43. What works what doesn’t( Most “cluck for your buck”) We need to determine the best“fit” for bup? Short-term detoxification Moderate-long term detoxification Maintenance Tapering off methadone All of the above?

  44. The Legacy 4 of original 6 drug free (0001) sites are continuing to utilize bup Betty Ford Center, CA Operation PAR, FL Center for Drug Free Living, FL Maryhaven, OH

  45. Possible gateway to more treatment Prior To BNX * * No BNX 100 BNX TX % of Patients 84 82 80 56 54 60 40 32 31 20 0 Completed Detoxification Continued in Treatment Brigham et al., CPDD2004

  46. Knowledge Gained/Lessons Learned • Medication trials can be done successfully in community treatment programs • Old dogs can learn new tricks • Patients really liked bup • Patients really don’t like clonidine • Buprenorphine as and alternative to methadone seems viable in the OTP*
