About this study

Official title: A Randomized Comparison of Protease Inhibitor-based Versus Non-nucleoside Reverse Transcriptase Inhibitor-based Antiretroviral Therapy for Initial Treatment of Individuals With AIDS-related Kaposi's Sarcoma in Sub-Saharan Africa

The primary purpose of this study is to determine whether a protease inhibitor-based antiretroviral regimen is more efficacious than a non-nucleoside reverse transcriptase inhibitor-based antiretroviral regimen in promoting the regression of KS tumor burden in persons with AIDS-related KS in Africa.

Read the detailed description

With the advent of the HIV epidemic, Kaposi's sarcoma (KS) is now the most common adult cancer in many parts of sub-Saharan Africa. In HIV-infected patients with KS in developed settings, the initiation of highly active anti-retroviral therapy (HAART) has been associated with regression of the tumor, in many but not all cases, even in the absence of conventional chemotherapy. However, it is not known which specific antiretroviral drugs or regimens are critical to convey HAART's anti-KS effect. In particular, it is not known whether the anti-KS effects of protease inhibitors (PI) in vitro and in animal models translate into improved clinical outcomes as compared to non-PI-based HAART regimens. To address this, we will determine whether a PI-based HAART regimen (lopinavir/ritonavir plus emtricitabine/tenofovir) is superior to a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based HAART regimen (efavirenz plus emtricitabine/tenofovir) in promoting the regression of KS tumor burden in persons with AIDS-related KS in sub-Saharan Africa. We will enroll 224 patients with AIDS-related KS in Kampala, Uganda, randomly assign them to either a PI-based HAART or an NNRTI-based HAART regimen, and observe them for one year to determine the response in their KS to therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lopinavir/ritonavir plus Emtricitabine/Tenofovir versus Efavirenz plus Emtricitabine/Tenofovir in people with Kaposi's Sarcoma and HIV Infections, run by University of California, San Francisco at 1 site in Uganda.

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 10 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 20 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Uganda. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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.

What does the primary outcome measure?

Blinded assessment of the change in the burden of KS lesions. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2014.
