Mission: support development of safe, effective, acceptable, and accessible rectal microbicides for all that need them

1100+ advocates, scientists, funders, policymakers from 6 continents – S. America/Latin America and Africa more active than ever!

Microbicides 2010

"Some lubes are probably better than others, but we don't know where any of the currently available products fall along the spectrum from good to bad. While we push for a safe and effective rectal microbicide, we must ensure that existing lubes don't facilitate HIV transmission. People have a right to this kind of information, and it's very past due."

IRMA: Research on Lubricant Safety Very Past Due

studies conducted so far
Studies conducted so far…
  • Some studiestested lubes in a laboratory to see if they killed HIV in vitro or enhanced HIV-1 replication in vitro.
  • Some studies tested lubes on rectal tissue in mice to see if they were toxic, irritating or caused damage.
  • Some studies used human tissue (taken from the vagina or rectum) and tested lubes in vitro to see if they were toxic, irritating or caused damage to the tissue.
  • Only one study has tested the effect of lubes on rectal tissue in humans.
  • Another study looked at the link between self-reported lube use during anal intercourse and testing positive for some rectal STIs.

Lube survey (2007)… the gift that keeps on giving!
  • General findings:
    • Presented in our 2008 report
    • Published in 2010
    • Used to decidewhichlubes to test

Lube survey (2007)…

the gift that keeps on giving!

  • Data amongwomenpresentedat AIDS2010
  • Data from L. America
  • Qualitative data presentedat M2012
slide10

Lube Safety Working Group

  • compile all available research data on lube safety
  • monitor research on an ongoing basis
  • develop basic materials on lube safety for HIV educators and advocates
  • conduct a series of global teleconferences to disseminate key messages
  • establish contact with regulators and manufacturers
  • identify areas for further research

50 researchers & advocates from around the world

slide11

Lube Safety Working Group

Challenge of Consensus (5 months later…)

  • How does all of this translate into real world use and real world risk?
  • Interpreting and describing implications
    • Lab, clinical, behavioural studies?
    • Petri dishes, animals, humans?
    • Which assays are more important?
    • Nonoxynol-9
  • Messaging
    • “Naming names”
    • Condom use; non-condom users?
  • Wording
    • “Safety”

based on current evidence

Unclear whether any particular type or brand of lube might increase, decrease, have no effect on acquiring HIV and/or rectal STIs

  • Using male or female condoms still considered best way to prevent acquiring HIV and STIs during AI
Based on current evidence:

IRMA Steering Committee, and Lube Safety Working Group

based on current evidence1

Condom-compatible lubes associated with decreased risk of condoms breaking, slipping

  • Not possible at this time to recommend for/against using lubes if having AI without condoms
  • Lube use on its own not proven method of HIV or STI prevention
Based on current evidence:

IRMA Steering Committee, and Lube Safety Working Group

The bottom line:More research is urgently needed to explore if there is a link between lube use and acquiring hiv and /or rectal stis

who unfpa fhi draft statement
WHO/UNFPA/FHI draft statement
  • Female Condom Technical Review Committee requested recommendations

The correct type of additional lubricant for male latex and female condoms can be bulk procured with either male or female condoms, if justified by programmatic requirements.

who unfpa fhi draft statement1
WHO/UNFPA/FHI draft statement
  •  Specific recommendations related to:
    • osmolality
    • lubricants containing polyquaternary compounds
    • pH levels according to primary intended target population
    • lubricants containing spermicides, medicinal and other active substances
u s cdc
U.S. CDC
  • Time-limited internal Lube Safety WG looking at data, making recommendations to CDC:
    • potential data collection
    • potential research gaps to address
    • potential review of existing content and need for new messaging
  • Testing lubes in monkeys
  • Strong emphasis on rectal but also looking at vaginal and penile tissue, HIV/STI transmission
upcoming study results
Upcoming study results
  • Updated lube data from Charlene Dezzutti
    • Glycerin-free, aqueous-based lubes
  • U.S. CDC testing lubes rectally in monkeys
  • Project AWARE (9 clinics across U.S.)
    • Info on lubes used rectally
    • Lube-incident STI association in MSM
  • Douche/enema survey (global; 3,000 people)
    • Info on douches/enemas used/use patterns
lube safety research agenda

Potential

  • Identify assays needed to assess a broader range of products
    • including oil- and silicone-based lubes
  • Encourage more lab testing of more products
  • Take into account use patterns and product combination
    • including adding water, saliva, vaginal fluid
    • Use of lubes and douches/enemas
    • Eventually lubes and RMs
Lube safety research agenda
lube safety research agenda1

Potential

  • Support clinical studies to expand data based on testing in humans
  • Determine research required to evaluate HIV andSTI risks
  • Support new epi and socio-behavioural studies to assess lube use patterns and HIV/STI links
Lube safety research agenda
lube safety research agenda2

Potential

  • Research roadmap:
  • How does all of this translate into real world use and real world risk?
  • Identify NEW resources to achieve this
  • In-person consultation?
