T-20 Plus a Selected Anti-HIV Treatment in HIV-Infected Children and Adolescents

The Area Under the Plasma Concentration-Time Curve (AUC) is a measure of the plasma concentration of the drug over time. It is used to characterize drug absorption. AUC was calculated from plasma concentration-time data (on Day 7) using standard non-compartmental pharmacokinetic methods.

The Plasma Concentration (Cmax) is defined as maximum observed analyte concentration. Cmax was calculated from plasma concentration-time data (on Day 7) using standard non-compartmental pharmacokinetic methods.

Tmax is defined as actual sampling time to reach maximum observed analyte concentration.

Ctrough is defined as the lowest concentration that a drug reaches before the next dose is administered.

The ratio of the area under plasma concentration-time curve from time 0 to 12 hours of Enfuvirtide Metabolite (Ro 50-6343) versus enfuvirtide was calculated.

An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is a significant medical event.

Pediatric AIDS Clinical Trials Group (PACTG) toxicity grading scale was used for reviewing and grading clinically significant laboratory abnormalities. PACTG Grade 3 and Grade 4 were considered Severe and life threatening, respectively.

Numbers of Participants With worst local injection site reactions were reported. Localized injection site reactions like erythema, induration, pruritus, nodule and cyst, and ecchymosis were recorded.
