Open Clinical Trials
The federal government's AIDSinfo Web site includes a clinical trials section that features an introduction to HIV/AIDS research and study listings from the National Institutes of Health's ClinicalTrials.gov database. AIDSinfo also offers personalized advice about clinical trial participation via email (ContactUs@AIDSinfo.nih.gov), an interactive Web site (www.aidsinfo.nih.gov/live_help; specialists available Mon.-Fri. 9:00 am-1:00 pm PT), and a toll-free telephone service (800-874-2572, international 301-874-2572; specialists available Mon.-Fri. 9:00 am-2:00 pm PT). CenterWatch is a commercial Web site that includes trial listings for many diseases, including HIV/AIDS and related conditions. The Community Research Initiative of New England (CRINE) offers a searchable database of trial listings for the Northeast.
Most U.S. government-sponsored HIV/AIDS trials are conducted by the adult and pediatric AIDS Clinical Trials Group (ACTG). The National Center for Complementary and Alternative Medicine (NCCAM) conducts trials of complementary therapies for conditions related to HIV and its management. The HIV Vaccine Trials Network (HVTN) is an international collaboration testing preventive vaccines.

The company recently announced the initiation of a new open-label Phase IIIb trial called GRACE (Gender, Race and Clinical Experience), which will study sex- and race-related differences in the drug's efficacy and tolerability. While HIV treatment trials have historically included a majority of men, GRACE will enroll 70% women. "Women who participate in GRACE will play a very important role in advancing the understanding of HIV treatment in women," said treatment advocate Dawn Averitt-Bridge.

This randomized Phase IV study, sponsored by the Department of Veterans Affairs, will attempt to determine how PIs contribute to the development of diabetes in people with HIV -- in particular, whether PIs impair insulin secretion and increase the production of glucose by the liver. In order to separate out the effects of PIs from those of HIV itself, this study will enroll HIV negative volunteers. Participants will be randomly assigned to receive either a single dose of a PI or placebo. Insulin secretion will be assessed using the hyperglycemic clamp technique. Somatostatin, growth hormone, and glucagon will be infused before and during the clamp study. Liver glucose production will be measured in the fasting and hyperinsulinemic (excess insulin) states.
This study aims to enroll 80 healthy, HIV negative participants 18-72 years of age. Volunteers may not have medical conditions associated with insulin resistance, such as obesity or elevated blood fat levels, and may not be taking glucocorticoids, growth hormone, niacin, or antipsychotic medications. Women may not be pregnant. This study will take place at the San Francisco Veterans Affairs Medical Center (415-221-4810 ext. 2118 or ext. 3395). www.clinicaltrials.gov/ct/show/NCT00259727 (RCD-005-05S; H574-23263).
"New Approaches to HIV Prevention"). The Centers for Disease Control and Prevention (CDC), in conjunction with the San Francisco Department of Public Health (SFDPH), the AIDS Research Consortium of Atlanta, and the Fenway Community Health Center in Boston, is conducting a double-blind Phase II trial to assess whether tenofovir can help prevent infection, as suggested by animal studies.
Participants will receive either daily oral tenofovir or placebo, and will be followed every three months for two years. This phase of the study will focus on the safety of the drug and whether use of a potentially protective agent will lead to an increase in high-risk sexual behavior. Because it is not yet known whether tenofovir can prevent HIV infection -- and because some subjects will receive placebo -- participants should continue to practice safer sex, and will receive risk-reduction counseling and free condoms. If any participants become infected, SFDPH will facilitate referrals for HIV care and treatment.
Eligible participants must be sexually active HIV negative men aged 18-60 years who have sex with men or transgender (male-to-female) women. Exclusion criteria include certain medical conditions (including impaired kidney or liver function and bone disease) and use of certain drugs (including nephrotoxic medications). The study is enrolling participants in San Francisco (415-554-8888; www.helpfighthiv.org/projt.htm), Atlanta (404-876-2317; www.aidsresearchatlanta.org/TheT), and Boston (617-927-6450). www.clinicaltrials.gov/show/NCT00131677 (CDC-NCHSTP-4323).
Eligible participants must be HIV negative and HSV-2 positive; there are no age restrictions. Subjects will be randomly assigned to receive either 400 mg twice-daily acyclovir or placebo. Follow-up visits will occur monthly for one year; participants will be tested for STIs at each visit and treated as necessary.
This study aims to recruit more than 3600 participants worldwide. Women will be enrolled in Africa, while men who have sex with men will be enrolled in Peru and in the United States, in New York City (212-388-0008), San Francisco (415-437-4782; www.helpfighthiv.org/acestudy.htm ), and Seattle (email@example.com). www.clinicaltrials.gov/ct/show/NCT00076232 (HPTN 039).
One such study, sponsored by CONRAD and the University of California at Los Angeles, is the first-ever trial of rectal use in humans of UC-781, an investigational NNRTI gel microbicide. This Phase I study is designed to assess the product's safety and acceptability, not its efficacy.
Eligible participants must be at least 18 years of age, HIV negative, and have experience with receptive anal intercourse. Women may not be pregnant or breast-feeding, and all participants must agree to use condoms. Exclusion criteria include certain medical conditions and laboratory abnormalities. Subjects will be randomly assigned to use a gel containing one of two concentrations of UC-781 or else placebo. During Stage 1, they will receive a single dose at the clinic. During Stage 2, they will self-administer the gel once daily for seven days. Study evaluations will include flexible sigmoidoscopy.
This study will enroll 36 participants at the UCLA Center for HIV Prevention Research in Los Angeles (310-825-9254 or firstname.lastname@example.org). www.clinicaltrials.gov/ct/show/NCT00408538 (U19-AI060614:P4).
A related study called the Anorectal Microbicide Project will assess rectal health, sexual behavior, and potential acceptability of rectal microbicides. In this observational, cross-sectional study, men and women will participate in computer-assisted interviews concerning their behavioral repertoire surrounding anal intercourse, rectal symptoms, and healthcare. Participants must be at least 18 years of age, with or without a history of receptive anal intercourse, and willing to undergo STI testing and rectal exams. This study aims to enroll nearly 900 participants in Los Angeles (310-358-2429) and Baltimore (410-502-5949). www.clinicaltrials.gov/ct/show/NCT00377221 (U19-AI060614:P3).
New Approaches to HIV Prevention, HIV vaccine research includes both candidates aimed at preventing HIV infection and those designed to improve immune response after infection. Below is a sample of NIAID vaccine trials currently enrolling HIV negative volunteers; for a more comprehensive list, visit www.clinicaltrials.gov and search for "HIV vaccine."
Eligibility criteria are similar for all of the following trials. Participants must be 18-50 years of age, HIV negative, and in good general health. Exclusion criteria include participation in previous HIV vaccine trials, recent receipt of various other vaccines, certain medical conditions (including heart disease, diabetes, and hepatitis B or C), spleen removal, use of certain medications, and adverse reactions to past vaccines (and, in some cases, allergy to eggs). Women may not be pregnant or breast-feeding, and participants must agree to use effective contraception.
