Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

* Participants with Cushing's syndrome;
* Untreated hypothyroidism or hyperthyroidism. A participant who is euthyroid on a stable replacement dose of thyroid hormone is acceptable provided the thyroid stimulating hormone (TSH) performed within 30 days of screening is within normal drug range;
* Recent therapy with agents with significant systemic myelosuppressive, neurotoxic, pancreatotoxic, hepatotoxic or cytotoxic potential within 3 months of study start or expected need for such therapy at the time of enrollment; or therapy with methadone or ribavirin/interferons or treatment with neurotoxic drugs or drugs that affect CYP3A4;
* Participants with obstructive liver disease;
* Active alcohol or substance use sufficient, in the Investigator's opinion, to prevent adequate compliance with study therapy or to increase the risk of developing pancreatitis or chemical hepatitis;
* Proven or suspected acute hepatitis in the 30 days prior to study entry;
* Intractable diarrhea (=6 loose stools/day for at least 7 consecutive days) within 30 days prior to study entry;
* Inability to swallow capsules;
* Active peripheral neuropathy;
* Presence of cardiomyopathy (due to any cause) or any significant cardiovascular disease, such as unstable ischemic heart disease;
* Known, clinically significant cardiac conduction system disease.
* Baseline laboratory values measured within 2 weeks prior to initiating study drugs as follows:

1. calculated creatine clearance <60 mL/min as estimated by the Cockcroft-Gault equation;
2. total serum lipase = 1.4 times the upper limit of normal;
3. liver enzymes (AST, ALT) = 5 times the upper limit of normal;
4. total serum bilirubin = 1.5 times the upper limit of normal.
* Hypersensitivity to any component of the formulation of study drug;
* Prohibited therapies;
* Any other clinical conditions or prior therapy that, in the opinion of the Investigator, would make the participant unsuitable for study or unable to comply with the dosing requirements;
* Prisoners or participants who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness must not be enrolled into this study.

Summary
Brief summary
The purpose of this study is to evaluate the safety, tolerability and antiviral effects of atazanavir (ATV) plus ritonavir (RTV) versus a combination drug of lopinavir (LPV) plus RTV. A combination drug containing tenofovir (TDF) and emtricitabine (FTC) will also be taken by participants in both arms.
