Brief Summary:
The goal of this study is to examine whether enfuvirtide T20 Fuzeon has continued anti-HIV activity in patients experiencing an incomplete virologic response to an enfuvirtide-based regimen
Detailed Description:
Some patients do not achieve an undetectable HIV viral load with an enfuvirtide T20 Fuzeon based antiretroviral regimen As a consequence enfuvirtide resistant virus can emerge It is not yet known if enfuvirtide has continued virologic or immunologic benefit after the drug-resistant variant emerges Interrupting enfuvirtide may reduce the accumulation of enfuvirtide mutations and may allow for a potent response of enfuvirtide with future regimens
Subjects must have evidence of viral replication HIV RNA 1000 copiesml on two consecutive measurements while on a stable antiretroviral regimen containing enfuvirtide Patients will then interrupt enfuvirtide while continuing all other antiretroviral agents Subjects will be seen weekly for four weeks every two weeks for an additional 8 weeks and then every four weeks through week 48
Plasma HIV RNA levels and CD4CD8 T cell counts will be measured in real time at each visit and provided to the referring primary care physician Subjects will be allowed to resume enfuvirtide at any time during the course of this study Subjects will be encouraged to resume enfuvirtide with or without modifying the background regimen if plasma HIV RNA levels increase by 05 log on two consecutive occasions Subjects are seen every four weeks for 24 weeks after enfuvirtide is resumed
Plasma will be collected at those visits for HIV RNA and stored for retrospective genotypephenotype evaluation
