Parsons, Ph.D. Distinguished Professor, Department of Psychology Director, Center for HIV/AIDS Educational Studies & Training (CHEST) Hunter College and the Graduate Center of the City University of New York (CUNY) Presented at the OHTN 2013 Research Conference: November 19, 2013

3 My goals Present on the first (and thus far only) behavioral intervention focused on HIV medication adherence to result in positive immunologic and virologic outcomes. Discuss evolution of this project into a 2 nd RCT and a planned effectiveness trial Highlight the problems and mistakes we made along the way.

4 Background & Significance Alcohol use negatively impacts the health of people who are HIV+. Alcohol has been commonly identified as a factor related to HIV medication adherence. Even recreational alcohol use has been shown to be associated with non-adherence.

5 Background & Significance Optimal HAART adherence is less often achieved in patients with alcohol problems due to: beliefs and misunderstandings about potential negative interactions between alcohol and HAART (interactions which are typically not true!) exacerbations of side effects by alcohol use immediate cognitive and behavioral changes from alcohol use (e.g. perceptions of time and maintenance of routines)

6 Study Description Project PLUS wasaimed at simultaneously improving adherence to HIV meds and reducing drinking among heavy drinking HIV+ men and women in NYC.

12 Methods Eligibility Confirmed HIV Seropositive Status On HAART AUDIT score >= 8 Heavy drinking >16 drinks/week for men; > 12/week for women Alcohol problems > Other Drug Problems (MAJOR PROBLEM) At least 18 years old Random Assignment Using urn randomization Matching on gender, AUDIT score and CD4 count Two arms intervention education (attention control) (PARTIAL MAJOR PROBLEM)

13 Assessment Adherence: Biological measures: viral load and CD4 count Self-report measures: Time Line Follow Back (TLFB) calendar for the past 14 days Alcohol use: Self-report measures: TLFB for the past 14 days Number of Standard drinks summed number of standard drinks across the 14-day period. Drinks per drinking day -total number of standard drinks in the past 14 days divided by the number of days during that period in which the participant had at least one alcoholic drink NOTE No biological measures of alcohol use

14 The Intervention First two sessions focus exclusively on Motivational Interviewing (MI). Client picks which behavior to focus on first Structured computer-generated personalized feedback on both behaviors is provided Also covers the Information component of the IMB model

15 Motivational Interviewing A change plan is formulated with the participant: The changes I want to make are: The most important reasons why I want to make these changes are: The steps I plan to take in changing are:

16 The Intervention Last six sessions use MI and Cognitive Behavioral Skills Building A menu-approach is used. Following a functional analysis, specific skills building sessions are chosen based on individual needs of each client and are assessed through a case conceptualization

17 Functional Analysis Conducted for each behavior in order to best select skillbuilding sessions most appropriate for each client

18 Cognitive Behavioral Skills Building Provider chooses 3 modules for each behavior based on client s skills deficits ALCOHOL Coping with Triggers to Drink Managing Thoughts to Drink Refusal Skills Moderated Drinking EITHER Increasing Pleasant Activities Managing Negative Moods Making Time For Self ADHERENCE Managing Side Effects Communication with Health Care Providers Managing Cravings to Skip Medication Managing Thoughts to Skip Medication

19 Control Condition The control condition consists of eight individual sessions with health educators, using videotapes which provide education around HIV, adherence, and alcohol use, followed by a structured discussion of the information covered. DANGER, DANGER, DANGER!!!!

20 Non-Hazardous Drinkers (n = 167, 53.87%) Baselined and Randomized Hazardous Drinkers (n = 143, 46.13%) Treatment Condition (n = 65, 45%) Mean (SD) sessions = 6.45 (2.31) Control Condition (n = 78, 55%) Mean (SD) sessions = 6.95 (2.18) 3 Month Follow Up not completed (n= 12) Completed 3 Month Follow Up (n = 53, 84%) Completed 3 Month Follow Up (n = 68, 87%) 3 Month Follow Up not completed (n = 10) 6 Month Follow Up not completed (n = 12) Completed 6 Month Follow Up (n = 53, 84%) Completed 6 Month Follow Up (n = 62, 83%) 6 Month Follow Up not completed (n = 16)

21 Adherence Results The primary outcome measures were changes in log viral load and CD4 count from baseline to 3-month follow-up. At baseline, the two groups did not differ significantly in their viral load or CD4 counts. At 3-months, there was a significant time x condition interaction such that intervention participants demonstrated significant decreases in viral load, and significant increases in CD4 count, compared to those in the control condition.

22 Log Viral Load Intervention Control 2 Baseline 3-Months

23 CD4 Count Baseline 3-Months Intervention Control

24 Drinking Results Participants in both conditions reported significant decreases in both the number of standard drinks they consumed from baseline to 3 months, F (1, 112) = 62.7, p <.001. Similarly, all participants reported significant decreases in number of drinks per drinking day from baseline to 3 months, F(1, 112) = 35.1, p <.001. There were no significant time by condition interaction effects for these variables. Attention control conditions may change behavior due to assessment effects or just the effects of being in a study. Or it may be that they work! No good biologic measures for alcohol exist.

25 Results at 6 months At the 6-month follow-up visit, there were no significant differences between individuals in the intervention and control condition on any outcome variable for adherence or drinking Average log viral load and CD4 counts remained better among participants in the intervention condition, but the time-by-condition interaction effect did not achieve statistical significance. Drinking remained lower in both groups, but the interaction effect was not significant. PROBLEM: NO BOOSTERS

26 Summary This is the first published behavioral intervention to document efficacy across viral load, CD4 count, and selfreported adherence. Both the intervention and the educational control sessions were equally efficacious in reducing drinking behaviors. The reduction in the magnitude of the intervention s efficacy at 6-month follow-up indicates the importance of intervention booster sessions.

27 Moving beyond PLUS

28 The Meth Epidemic In the first several months of 2004, increasing attention began to focus on the epidemic of crystal methamphetamine among gay/bisexual men in NYC and other urban areas.

29 The Meth Epidemic Gays' Use of Viagra and Methamphetamine Is Linked to Diseases(NY Times ) Crystal Meth Linked to AIDS in New York: Party drug increases HIV risk among gays(reuters ) Rare and Aggressive H.I.V. Reported in New York (NY Times )

30 The Meth Epidemic Party, Play And Pay: Multiple partners. Unprotected sex. And crystal meth. It's a deadly cocktail that has stirred new fears about the spread of HIV (Newsweek )

31 Our own research Through our community-based surveys, we identified a large increase in methamphetamine use among MSM. Use was significantly higher among HIV+ MSM. Also identified clear relationships between meth use and sexual risk behaviors.

32 Meth and Adherence Meth use and dependence were associated with poor adherence and increased viral load. Meth use has many negative effects on the health of people living with HIV. Because of the epidemic we felt an urgent need to take PLUS and apply it to meth-using MSM

33 ACE: Intervention Targeting Medication Adherence and Methamphetamine Use for HIV+ MSM 33 Principal Investigator: Co-Investigator: Project Director: Clinical Supervisor: Education Supervisor: Neuropsych Coordinator: Senior Data Analyst: Recruitment Director: Graphic Designer: Jeffrey T.

34 Study Description Project ACE isaimed at simultaneously improving HIV medication adherence and reducing meth use among HIV+ MSM in NYC. Eight-session, manual-driven, individual intervention using a combination of Motivational Interviewing (MI) and Cognitive Behavioral Skills Building (CBST), adapted from Project PLUS. Driven by the IMB Model of Fisher & Fisher

35 Methods Eligibility Confirmed HIV+ and taking HAART >3 missed med days in the last 30 >3 days of Meth use in the last 90 days Past sex with men At least 18 years old Random Assignment Using urn randomization Two arms: intervention or education (attention control) WTF?! You didn t learn the first time???

38 Timing sucks The meth epidemic identified in First ACE grant submission in late Second ACE grant submission in early ACE was funded in Sept, 2007 By 2008, rates of meth use dramatically decreased among MSM in NYC! In 2008, only 6% of gay men in New York City reported using meth during the previous 12 months. That's a 57% drop from the percentage reported in 2004.

41 ACE We completed recruitment and enrollment, and just finished our last round of follow-ups. We ended up with a sample size of 210 after YEARS of recruitment, and trying virtually every approach in the book active, passive, internetbased, RDS, etc. Analyses have begun. More later.

42 Where do we go from here PLUS and ACE were tested in a very controlled environment (CHEST). There were numerous inclusion/exclusion criteria that led to a less generalizable sample. Therapists delivering PLUS were highly trained, and received extensive supervision. PROBLEM: Would we get the same results in actual HIV clinic settings, using the actual staff?

43 Where do we go from here So, we submitted an application to NIAAA for a comparative effectiveness trial to test PLUS in 3 clinics in NYC. Will train existing clinic staff in MI, CBT, and the intervention itself, but will provide limited on-going supervision. Limited eligibility criteria, few exclusion criteria. The fact that patients come to clinic regularly for care will permit natural booster sessions. Funded, and the trial will begin in 2014.
