The Master PRAM schema is designed to allow new therapeutic arms to be studied as "rolling screens" through multiple generations of PRAMs. There is a common, "linking" regimen between any 2 sequential PRAM generations that will permit an indirect comparison of included therapies. (NOTE: Due to significant changes in study design between PRAM 1 and PRAM 2, there is no "linking" arm between them. The linkage will be reinstated from PRAM 2 and subsequent PRAM generations.) The therapeutic potential of the treatment arms is assessed by their ability to decrease HIV copy numbers as defined by plasma HIV-1 RNA copy number. Once accrual to a PRAM is complete, a new treatment comparison will open for accrual.
