Summary

Saquinavir and Atazanavir are drugs used in combination therapy to treat HIV disease. Saquinavir is currently available in a 200 milligram capsule. Most individuals currently on saquinavir require to take 5 tablets twice a day. In an attempt to reduce this number of pills, a new capsule has been developed containing 500 milligrams of saquinavir. This study will assess: i) blood drug levels in individuals taking both saquinavir formulations, ii) blood drug levels in individuals taking both saquinavir formulations when given with atazanavir, iii) 48 weeks of follow up for individuals receiving the new saquinavir formulation with atazanavir as HIV therapy.

NRTIs + SQV/RTV 1000/100 mg BID using 200 mg SQV capsules switched at entry to ATV/SQV/RTV 300/1500/100 mg QD using 500 mg SQV tablet for 48 weeks with PK at days 0 and 8.

DRUG

cross-over arm

either ATV/SQV/RTV 300/1500/100 QD (500 mg SQV tabs) for 7 days then after PK SQV changed to 1600 mg QD (200 mg caps) with PK day 15, or ATV/SQV/RTV 300/1600/100 QD for 7 days with switch to SQV 1500 mg QD. After day 15 PK both groups switch to ATV/SQV/RTV 300/1500/100 QD to week 48
