Objective: To assess both the benefits and risks of an 8-week treatment interruption associated with a six to nine-drug rescue regimen in patients with multiple treatment failures. Design: A randomized comparative controlled trial in 19 university hospitals in France. Patients: Sixty-eight HIV-infected patients with multiple previous treatment failures and CD4 cell counts less than 200 3 10 6 cells/l and plasma HIV-1-RNA levels of 50 000 copies/ml or greater. Measurements: The primary efficacy outcome was the proportion of patients with at least a 1 log 10 decrease (copies/ml) in the plasma HIV-1-RNA level after 12 weeks of therapy. Results: Treatment interruption followed by multidrug salvage therapy led to a greater proportion of patients achieving virological success (i.e. 1 log 10 decrease) at 12 weeks compared with patients receiving multidrug therapy alone (62 versus 26%, intent-to- treat analysis; P ¼ 0.007). The median decrease in the HIV-1-RNA level was 1.91 and 0.37 log 10 copies/ml (P ¼ 0.008), respectively. Treatment interruption led to an increase in the number of sensitive drugs of the multidrug regimen (71 versus 35% of regimen with at least two sensitive drugs; P ¼ 0.004). Factors associated with virologi- cal success were treatment interruption, the reversion of at least one mutation to wild type, adequate plasma drug concentration, and the use of lopinavir. Conclusion: Treatment interruption was beneficial for treatment-experienced HIV- infected patients with advanced HIV disease and multidrug-resistant virus. & 2004 Lippincott Williams & Wilkins AIDS 2004, 18:217–226 Keywords: HIV, salvage therapy, treatment failure, treatment interruption Copyright © Lippincott Williams & Wilkins.
