Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Rosuvastatin tablets, dose 10 mg daily (5 mg daily in Asian participants), taken once daily for 12 weeks. Participants assigned to this intervention will continue ritonavir-boosted anti-retroviral therapy.
Intervention code [1] 285236 0
Treatment: Drugs
Comparator / control treatment
Switching of ritonavir-boosted protease inhibitor to an alternative anti-retroviral agent as part of combination anti-retroviral therapy for HIV-1 infection.

Valid switch options are based on the U.S Department of Health and Human Services anti-retroviral guidelines in adolescents and adults, and include nevirapine tablets (400 mg daily), rilpivirine tablets (25 mg daily), raltegravir tablets (400 mg twice daily) and unboosted atazanavir tablets (400 mg daily). Final decisions regarding switch medication will be made by the treating physician, but will be for a duration of 12 weeks

Safety parameters (includes HIV-1 RNA level, clinical adverse events, serious adverse events, laboratory adverse events, modifications to anti-retroviral therapy)

Clinical adverse events (for example, skin rashes) or laboratory events (for example, elevated liver enzymes) occurring during the study will be clinically assessed. Any adverse events ongoing at Week 12 deemed related to study drug by an investigator will be followed up for at least 30 days, or until resolution. Additional unscheduled visits and pathology tests may be required as part of this follow-up.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a randomized, open-label, 12-week prospective trial. Sixty (60) eligible subjects will be randomly allocated 1:1 to either:
(A) switch their existing ritonavir-boosted PI to another potent ART drug with lesser effects on serum cholesterol selected by the investigator; OR
(B) continue ritonavir-boosted PI-based ART and commence rosuvastatin 10 mg daily (5 mg daily in Asian participants).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be stratified by baseline protease inhibitor type and by baseline total cholesterol (>7.0 mmol/L or <=7.0 mmol/L [275 mg/dL]). Randomisation within each stratum will be performed by St. Vincent's Centre for Applied Medical Research staff otherwise not involved in the study. A computerized random number generator will be used to produce a random order of interventions.
