PrEP for MSM in the US
•
•
•
•
•
New HIV diagnoses among MSM occur at
>44 times the rate among other US men.1
July 16, 2012: US FDA approved Truvada®
for use by adults as daily oral PrEP.2
Surveys of US MSM show willingness to
use PrEP (44-79%), concerns about cost,
risk compensation, side effects.3-7
Project PrEP Talk: 8 two-hour focus groups
Jan-June 2012 in Providence, RI.
Each enrolled 4-6 HIV-negative MSM with
recent non-seroconcordant UAI (n = 38)
–
Mean age = 38.5 (range = 21-61), 79% White,
37% gay, 45% unemployed, 39% no health
insurance, 45% transactional sex in past 6m,
39% sex with men and women in past 6m.

Knowledge, Acceptability, and
Risk Compensation
• Knowledge low for PrEP and all other biomedical strategies
• Majority willing to use PrEP, but motivations and expected
benefits (for individuals and community) varied
– "I would take that pill every day because I'm going to have unsafe sex if I take it or if I
don't take it. So for someone like me, I think it's great."
– "If there's a person… who has HIV that is afraid to have sex with me… it hurts me too
that we can't enjoy that intimacy."
• Motivations for unwillingness to use PrEP also varied
– "I think I would stick to what I'm doing … [my partner and I are] always safe."
– "Rather than take pills because I'm doing risky behavior, I'd just stop the risky behavior
first. Taking pills… that's whack to me."
– "If my girlfriend found out I was taking something like that, you know, why do I need to
be taking that?… Am I banging hoes? Our relationship's over period… I just wouldn't
take it all.“
• Many predicted increases in risk behavior among other PrEP
users; fewer predicted personal increased risk-taking
Significance of FDA Approval for
Acceptability
• Some saw FDA approval as irrelevant, for varying reasons:
– "The street pharmacist doesn't wait for FDA approval."
– "I would definitely do it even though it was not FDA approved… I
don't mind being a guinea pig."
– "The fact that it's been approved for a purpose and is being
used for a related purpose – it would be fine by me."
• FDA approval was essential for others to use PrEP, also for
varying reasons:
– "I would wait till the FDA approved it just to be safe. It would
make my mind more relieved."
– "The FDA and the drug business is one of the most awful, bad,
bad, bad, bad, like, industries in – in our country… It's constantly
FDA approves medications that kill people… So of course, if they
haven't approved it yet, God knows what could happen to you."
Conclusions
•
•
•
•
Willingness to use PrEP is complex and draws on a variety
of motivations, perceived barriers, and anticipated
benefits or harms. Easily adaptable behavioral
interventions are needed to support use.
FDA approval will tip the balance in favor of PrEP
acceptability among some potential users, but many will
make acceptability decisions based on other factors – FDA
approval will play a more indirect role.
Impact of FDA approval on PrEP financing and insurance
coverage may be more important; cost of pills and
prescription was the primary barrier to use.
Supportive interventions for PrEP users should account for
perceptions of individual and community behavior,
particularly in addressing risk compensation.
