Study of Reyataz in HIV-infected Patients With Lipodystrophy Syndrome

Mean changes from Baseline in trunk-to-limb fat ratio as measured by DEXA, an x-ray scan used to measure bone mineral density. Clinical improvement is associated with a decrease in values. (Baseline trunk-to-limb fat ratio values can be found in the Baseline Characteristics section.)

Mean changes from baseline in trunk-to-limb fat ratio as measured by DEXA, an x-ray scan used to measure bone mineral density. Clinical improvement is associated with a decrease in values.(Baseline trunk-to-limb fat ratio values can be found in the Baseline Characteristics section.)

The mean percent change from baseline in physical signs of lipohypertrophy, as assessed objectively by changes in visceral adipose tissue (VAT) area (cm2) by computed tomography (CT) scans and by changes in trunk fat (kg) by DEXA. Clinical improvement is associated with a decrease in values. (Baseline values can be found in the Baseline Characteristics section.)

The mean percent change from baseline in physical signs of lipoatrophy, as assessed objectively by changes in peripheral adipose tissue (ie, limb fat (kg) by DEXA and in subcutaneous adipose tissue (SAT) area by CT scans. Clinical improvement is associated with stable values, or an increase in values. (Baseline values can be found in the Baseline Characteristics section.)

The mean percent change from baseline in total body fat by DEXA and in total adipose tissue (TAT) area by CT scans. Total body fat and TAT are both associated many factors (trunk fat + limb fat + other [weight, etc]), and thus clinical improvement cannot be predicted based solely an increase or decrease of these values. (Baseline values can be found in the Baseline Characteristics section.)

Mean percent changes from baseline in fasting total, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and non-HDL cholesterol, triglycerides, and apolipoprotein B

HOMA-IR is an index used in evaluation of obese patients at risk for type 2 diabetes which requires fasting glucose and insulin concentrations. It is a mathematical model based on the theory of a negative feedback loop between the liver and β-cells that regulates both fasting glucose and insulin concentrations and can be used to estimate pancreatic β-cell function and degree of insulin resistance. HOMA-IR normal values are between 2 and 2.5. HOMA-IR ≥ 2.5 indicates insulin-resistance.

Mean changes from baseline in proportion of waist to hip measurements.

Percentage of Participants with AEs, Serious AEs (SAEs), Deaths, and AEs leading to discontinuation. An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition. An SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a cancer, is a congenital anomaly/birth defect, results in the development of drug dependency or drug abuse, is an important medical event.

Percentage of participants with Abnormal Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), and Total Bilirubin (TBILI) measurements. Values for liver tests are graded using the modified World Health Organization (WHO) criteria. Grade 1 is mild, grade 2 is moderate, grade 3 is severe, grade 4 is life threatening or disabling.

Percentage of Participants with AEs leading to discontinuation of study therapy. An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition. All events listed in this table were SAEs, except for renal impairment and hypertriglycerideamia, which were an AEs (and did not meet the 5 percent threshold reported in Adverse Event module of this record).

Virologic rebound was measured from the first dose of study therapy to the first of the 2 consecutive measurements ≥400 c/mL. Time to virologic rebound was analyzed using life tables. Measured Values show the Kaplan-Meier cumulative proportion of participants without virologic rebound up to the end of the respective interval.

Mean change from baseline in CD4 count among treated subjects
