AntiViral-HyperActivation Limiting Therapeutics (AV-HALTs) are an investigational class of antiretroviral drugs used to treat Human Immunodeficiency Virus (HIV) infection. Unlike other antiretroviral agents given to reduce viral replication, AV-HALTs are single or combination drugs designed to reduce the rate of viral replication while, at the same time, also directly reducing the state of immune system hyperactivation now believed to drive the loss of CD4+ T helper cells leading to disease progression and Acquired Immunodeficiency Syndrome (AIDS).
