The purpose of this program is to evaluate an effort to provide a comprehensive package of HIV prevention services of which post-exposure prophylaxis (medicines that may help prevent HIV infection after an exposure) can be a part. It will also include risk reduction information and testing for other sexually transmitted infections.

Condition Intervention Phase
HIV Transmission HIV Infections Drug: tenofovir + emtricitabine, lopinavir/ritonavir Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Pilot Project to Operationalize the Prevention Strategy of Post Exposure Prophylaxis Following Sexual Exposure to HIV in Combination With Educational Programming and Behavioral Risk Reduction Strategies in Los Angeles County

Further study details as provided by University of California, Los Angeles:

Primary Outcome Measures:
  • To provide a comprehensive package of HIV prevention services, of which PEP can be an integral component.

Secondary Outcome Measures:
  • To evaluate the acceptability, feasibility, and safety of administering PEP in easily acceptable, non-judgmental, culturally, ethnically and linguistically appropriate environments.

Estimated Enrollment: 100
Study Start Date: March 2010
Estimated Study Completion Date: March 2011
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: tenofovir + emtricitabine, lopinavir/ritonavir

    The preferred regimen will be tenofovir + emtricitabine, provided as a fixed-dose combination tablet as Truvada®. Dosing is 1 tablet by mouth once daily. For participants with a creatinine clearance 30-49 mL/min, dosing of Truvada is 1 tablet by mouth every other day. For patients with creatinine clearance <30 mL/min or on hemodialysis, Truvada should not be used. For intolerance to Truvada, Combivir (zidovudine 300mg/lamivudine 150mg)will be available to be taken as 1 PO BID. For highest-risk category exposures (receptive anal intercourse with a known or suspected HIV-positive source patient or in cases of suspected source drug resistance, see Schema, below) one of the following should be added to the above "standard" treatment, creating an "expanded" regimen:

    Preferred: Lopinavir/ritonavir (200mg/50mg), 2 tablets orally twice daily or 4 tablets once daily

    Other Names:
    • Truvada
    • Combivir
Detailed Description:

The Los Angeles County P-QUAD program is a combined effort of County, City, public health, community, academic, and private agencies and individuals in an effort to provide a comprehensive package of HIV prevention services of which PEP can be an integral component. These services are designed to be easily accessible, non-judgmental, culturally, ethnically, and linguistically appropriate to the relevant populations, community-based, and independent of ability to pay or insurance/documentation status. They will also provide vital linkages to associated services, routine HIV testing, and primary health care.

In its initial pilot project, 2 community-based sites will serve as facilities at which patients may present for screening for post-exposure prophylaxis services, as well as sexually transmitted diseases. At the sites, initial eligibility and testing will be performed, and an initial 14-day supply of PEP medications will be provided if appropriate, and referrals will be initiated. All subjects who are provided an initial 14-day supply will be required to return to the site for the remainder of the 28-day course of medication, follow-up testing, adherence counseling, risk-reduction programming, and other appropriate referrals. Follow-up with patients by phone, email, and mobile-phone text message will be used as appropriate to maximize program retention.
