In the first head-to-head comparison between two commonly used HIV treatments, researchers found one triple-drug therapy was significantly more effective at reducing HIV// viral load in the blood when used as a first-line treatment. Results of the clinical trial, which sought to determine from among three different therapies the optimal approach for patients beginning HIV treatment for the first time, will be reported at the XVI International AIDS Conference (AIDS 2006).
Of the two triple-drug approaches evaluated in the randomized trial, the therapy consisting of two nucleoside reverse transcriptase inhibitors (NRTIs) with efavirenz, a non-nucleoside reverse transcriptase inhibitor (NNRTI), suppressed the virus to undetectable levels in more participants than the three-drug combination of two NRTIs and a protease inhibitor called lopinavir/ritonavir. Moreover, a third regimen, efavirenz and lopinavir/ritonavir, performed nearly as well as the three-drug cocktail with efavirenz, suggesting initial therapy need not include NRTIs, a class of drugs that can produce intolerable side effects in some patients.
'Our findings suggest that the efavirenz plus two-NRTI regimen was the best of the three approaches as initial therapy, even in patients with relatively advanced HIV disease,' said Sharon Riddler, M.D., M.P.H., assistant professor of medicine in the division of infectious diseases at the University of Pittsburgh School of Medicine, who will present the findings at AIDS 2006.
'Also, we found that the NRTI-sparing two-drug combination of efavirenz and lopinavir had a similar level of effectiveness to the efavirenz plus two-NRTI regimen. When we started this study, we heard from physicians with concerns about using efavirenz in the absence of NRTIs. Now that we've completed the trial, there should be little doubt that patients can benefit from this 'nuke'-sparing treatment regimen when NRTI side effects are a problem,' she added.
