3TC or No 3TC for HIV With 3TC Resistance
A Randomized Study to Evaluate Virologic Response Following Discontinuation vs. no Discontinuation of 3TC in Patients Who Are Infected With HIV With Previously Documented Reduced Susceptibility to 3TC and Who Have Adequate Virologic Suppression on Combination Antiretroviral Therapy

The purpose of this study is to compare the effects of continuing or discontinuing 3TC treatment in the presence of HIV virus with 3TC resistance for persons who are on a regimen including least three other anti-HIV drugs. The overall aim is to determine whether continuing 3TC is of benefit in HIV-positive persons who have already shown resistance to this drug.
