On pp.6 of the cohort 2 document I thought this paragraph raised the question, How do they know? I am probably misinterpreting it and is probably used to cover all the legal bases. Be great if it turns out to be prophetic:
"Once the drug holiday begins, you will then be asked to return to the clinic every two weeks for two months (4 visits). One month after this, you will be asked to undergo a rectal biopsy procedure before you will restart anti-HIV medication, and will return monthly until no virus is detected in your blood. This may take one month, or several months, but it typically takes only one to two months. If prior to the scheduled time to restart your HIV medication, the physician finds that your HIV is found above 100,000 copies per ml or your CD4 cell counts drops to 350 or below, you will be told, and your study doctors will recommend that you restart the same HIV medications that you were taking before starting the planned drug holiday."
