AMD11070 is a new chemical entity that inhibits HIV-1 entry by binding specifically and reversibly to CXCR4, a coreceptor required by T-tropic virus for membrane fusion and entry into cells. The purpose of this study is to evaluate the safety and relative antiretroviral activity of AMD11070 in HIV-infected individuals who have demonstrated X4 -tropic virus in their plasma. With the ongoing development of other fusion and entry inhibitors and the need for alternative treatment options in patients (especially those with multidrug resistant virus), the demonstration of activity and safety of AMD11070 represents a potentially important advance in antiretroviral therapeutics. This will be the first study that determines the therapeutic potential of anti-CXCR4 compounds in HIV-infected patients.~Note: Study was previously suspended due to non-clinical reports of hepatotoxicity and histologic findings. Study has been completed.
The purpose of this study is to determine the safety and activity of AMD11070 in HIV-infected patients carrying X4-tropic virus.
