|•2560 subjects were screened; 56% had CCR5-tropic virus
|•About 10% of viruses changed from R5-tropic to Dual-mixed
or were non-phenotypable in the time period from screening until baseline.
|•So 90% of the subjects enrolled had CCR5-tropic virus at
|•Throughout these trials, it appears that the percentage of
isolates which are non-phenotypable using the Monogram tropism assay ranged
from 5 to 15%.
