Sir,
The next-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) etravirine (formerly known as TMC125) and the fusion inhibitor enfuvirtide have both shown improved efficacy over optimized background treatments in the DUET and TORO trials, respectively.1–3 Due to the cost of enfuvirtide and the need for twice-daily injections, switching from enfuvirtide to etravirine could improve convenience and tolerability, and reduce treatment costs. Two recent pilot studies have shown sustained HIV RNA suppression, 7 months after switching from enfuvirtide to raltegravir in virologically suppressed patients.4,5 A pilot study also showed sustained HIV RNA suppression for 6 months, after switching from enfuvirtide and protease inhibitors (PIs) to
