Subjects using inhaled corticosteroids or short-course systemic corticosteroids (less than or equal to 14 days) are eligible for enrollment.~* Subject has had treatment with radiation therapy or cytotoxic chemotherapeutic agents within 90 days prior to screening, or has an anticipated need for these agents within the study period~* Subject has had treatment within 30 days prior to first dose of investigational product for or an anticipated need during the study of any medications which can have interactions with the study medications, TDF, FTC, ABC, 3TC, ATV and/or RTV, as described in current product labelling~* Subject has had treatment with any previous abacavir-containing regimen

Study Arms:
- ATV + ABC/3TC (Type: EXPERIMENTAL): Subjects will change to ATV 400mg administered as two 200mg capsules orally, once daily and to the fixed-dose combination tablet of ABC 600mg/3TC 300mg (EPZICOM) administered as one tablet orally, once daily for 48 weeks. The subject's pre-study RTV will be discontinued.
- ATV + RTV + TDF/FTC (Type: ACTIVE_COMPARATOR): Subjects will continue their pre-study therapy, un-modified, of ATV 300mg administered as one capsule orally, once daily plus RTV 100mg administered orally, once daily plus fixed dose combination tablet tenofovir 300mg/emtricitabine 200mg administered as one tablet orally, once daily for 48 weeks.

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