The target rapamycin trough level will be 5-10 ng/mL. The initial dose will be dependent upon the type of HAART regimen. Subjects will continue on study protocol for six cycles as long as their KS is stable or continuing to respond to study medication. Treatment will be extended for up to six additional cycles if the subject has met criteria for a response. Subjects with no more than stable disease will have treatment discontinued after six cycles. Protocol treatment will be discontinued if the subject develops tumor progression, unacceptable toxicity or develops one of the protocol-defined reasons for treatment discontinuation at any time during the study.
