Drugs in Development


There are more than seven dozen anti-HIV drug candidates in various stages of testing. While some will be unsuccessful, the potential for newly developed medications as well as medication classes is better than ever before in the almost 25 years of the AIDS pandemic. The two main new drug classes in development are integrase inhibitors and maturation inhibitors. Integrase inhibitors interfere at the viral replication step in which HIV's genetic information is inserted into the host cell's DNA, thereby enabling the cell to start making copies of the virus. Integrase inhibitors target and disable HIV's integrase enzyme, which plays a key role in this replication step. Maturation inhibitors interfere with the final stages of HIV replication, in which viral copies are assembled and exit an infected cell. These drugs would prevent the virus from properly assembling, from forming a protective outer coat, or from emerging--also known as budding--from human cells. Below is a list of anti-HIV drugs in development, listed alphabetically in respective drug categories. Each listing also includes the drug's stage of development and company that is working on the medication. Entry Inhibitors AMD-070 (CXCR4 blocker); phase II; Anormed.
