If I might be a bit more verbose than Pariah, while still echoing his basic point:
I hope Pariah is wrong. However, from what I have read, the HIV virus is extraordinarily adaptive and fast evolving. As such, there is a strong possibility that no "trio of drugs" will remain effective against the virus for very long. In fact, I seem to recall reading that similar trials met early success only to see the drugs become ineffective as the virus changed.
