Open Clinical Trials for HIV/AIDS Treatments
AIDSinfo, a new Web site of the U.S. Department of Health and Human Services (DHHS), allows users to search for HIV/AIDS-related studies in a database maintained by ClinicalTrials.gov, a clinical trial listing for all diseases. The database may be accessed at either www.aidsinfo.nih.gov or www.clinicaltrials.gov. AIDSinfo also offers a toll-free telephone help line at 800-448-0440 (TDD/TTY 888-480-3739; international callers should dial 301-519-0459). Specialists are on hand Monday through Friday from 12:00 pm to 5:00 pm ET (9:00 am to 2:00 pm PT) to help locate trials and answer questions.
The AIDS Community Research Initiative of America (ACRIA) maintains a directory of HIV/AIDS clinical trials in New York state, New Jersey, Connecticut, and Philadelphia, and may expand to other areas of the country in the future. The ACRIA directory is available at www.criany.org/acria.html.
Call the telephone numbers below for more information about specific trials and a listing of study sites. Protocol (study) numbers, if available, are provided in parentheses at the end of each trial description.
GlaxoSmithKline's new PI candidate; or lopinavir, ritonavir, and GW433908. All participants will also take one or two nucleoside reverse transcriptase inhibitors (NRTIs) and tenofovir DF (TDF, Viread); the NRTIs are not provided by the study. Blood will be drawn and tested for drug levels at weeks 12, 24, and 48. A substudy (A5174S) will conduct more intensive sampling of blood drug levels; the first 20-25 participants enrolled in each arm will also be enrolled in the substudy.
Participants must be at least 18 years of age, have been on antiretroviral therapy for a total of at least one year, and have a viral load above 500 copies/mL within 60 days of prestudy screening despite being on a stable (unchanged) anti-HIV regimen for at least 12 weeks. Exclusion criteria include previous use of both lopinavir and amprenavir (Agenerase) for more than seven days each; untreated serious illnesses; or use of other experimental drugs, cancer chemotherapy, or immune-modulating drugs within 30 days of study entry. Women must not be pregnant or breast-feeding.
