update from iPrEx - more detail on drug levels
People will recall that iPrEx investigators questioned whether adherance to prophylaxis was the cause for transmissions in the active arm of the iPrEx study. Late Breaker #31LB reports on this. They compare plasma drug levels to those in an unrelated observed therapy trial STRAND with doing at 2, 4 and 7 days per week. The active arm had an overall preventative effect of 90% but when broken down by similarity to the STRAND data they found 76% efficacy at 2 day per week dosing levels, 96% at 4 and 99% at daily.
