Study Arms:
- saquinavir at baseline (Type: EXPERIMENTAL): patients receiving NRTIs + saquinavir + ritonavir 1000/100 mg BID at entry switch from 200 mg SQV capsules to 500 mg SQV tablets following PK at day 0. After PK at day 8 NRTIs ceased and regimen changed to ATV/SQV/RTV 300/1500/100 QD using 500 mg SQV formulation and continued to week 48
- other boosted PI at baseline (Type: EXPERIMENTAL): Patients receiving NRTIs + PI/RTV randomised at baseline to receive ATV/SQVRTV 300/1500/100 QD using 500 mg SQV formulation or ATV/SQV/RTV 300/1600/100 QD using 200 mg formulation. Following PK at day 7, SQV formulation switched with second PK assessment at day 15. Patients then receive ATV/SQV/RTV 300/1500/100 QD to week 48.

Based on this trial design, predict the completion outcome and termination type (if applicable).
