A Single arm Open Label Phase 2 trial of anti-CD4 Antibody UB-421 in Combination with Optimized Background Antiretroviral Therapy in Patients with Multi-Drug Resistant HIV-1 Infection (UB-421)

The purpose of this study is: (1) to see if a drug called UB-421 is able to control human immunodeficiency virus (HIV) infection in patients infected with a virus that has become so resistant to anti-HIV drugs that an effective treatment regimen cannot be put together using drugs currently approved by the US Food and Drug Administration (FDA); and (2) to see if UB-421 is safe for patients with multiple-drug resistant HIV.

LTNP Study

A small group of people who are HIV positive remain healthy for long periods of time without medications. These Long-Term Non-Progressors have properties within their immune systems that control the virus and can help researchers determine how their immune systems control HIV disease.
