About this study

The SUN Study is a Centers for Disease Control and Prevention (CDC)-sponsored multi-site prospective observational cohort study designed to better understand the incidence and etiology of metabolic and other complications related to effective HIV treatment and longer survival. The SUN Study is also providing a platform to evaluate a behavioral intervention designed to reduce HIV transmission through prevention counseling in routine care.

Read the detailed description

Effective antiretroviral therapy has significantly improved and prolonged the lives of HIV-infected persons. However, antiretroviral use has also been associated with a diverse array of "unnatural" metabolic complications and other adverse medical conditions. These problems, together with subsequent longer survival, have increased patients' risk for developing renal, hepatic, cardiovascular, neurological, rheumatologic, and other end-organ diseases, and cancers. Longer survival is also increasing the pool of HIV-infected persons capable of transmitting the virus, which could accelerate the pace of the U.S. epidemic; however, the ability of physicians caring for HIV-infected persons to incorporate prevention into their clinical practices and the effectiveness of this intervention have not been extensively evaluated.

The goals of the Study to Understand the Natural History of HIV and AIDS ("SUN" Study) are:

  • to monitor the incidence of metabolic and other medical complications related to the treatment of HIV infection and attendant prolonged survival,
  • to identify risk factors associated with the development of these metabolic and other medical complications,
  • to monitor the contribution of these complications and other conditions to the morbidity and mortality of HIV infection, and
  • to evaluate the efficacy of a structured program of prevention activities, which are integrated into the routine medical care of HIV patients to reduce HIV transmission.

The SUN Study is designed to enroll and follow for 5 or more years a cohort of up to 1,000 HIV-infected adults at HIV specialty care centers in four U.S. cities: Denver, Minneapolis, Providence, and St. Louis. Data will be gathered through longitudinal real-time chart review, biannual physical examination (e.g., body mass index [BMI], blood pressure), repeated non-invasive imaging (e.g., dual energy x-ray absortiometry [DEXA] scanning, carotid ultrasonography) and regularly scheduled laboratory testing (e.g., serum lipids, pap smears, and urinary microalbumin). Data collection and quality control will be managed by Cerner Corporation. After sufficient enrollment, (circa 200 persons per site) a structured prevention program to reduce HIV transmission will be introduced. The impact of this intervention will be evaluated both subjectively (e.g., self-reported change in behavior on an audio computer-assisted self-interviewing [ACASI] questionnaire) and objectively (e.g., change in sexually transmitted disease [STD] incidence).

Outcomes include determination of the incidence of therapy-related metabolic complications and other adverse conditions associated with longer survival, identification of risk factors for these complications and conditions, and reduction in both reported and objective measures of risky sexual behavior.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00146419, which also lists 16 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
