Brief summary

The primary objectives of this study are to evaluate the safety, tolerability and steady-state PK and confirm the dose of EVG/r in HIV-1 infected, antiretroviral treatment-experienced children 4 weeks to \<18 years of age. The study consists of 2 parts: Part A and Part B. Part A will enroll participants with suppressed viremia (HIV-1 RNA \< 50 copies/mL) or failing a current antiretroviral (ARV) regimen (HIV-1 RNA \> 1,000 copies/mL only for participants in Cohort 2, Part A) to evaluate the steady state PK and confirm the dose of EVG. Part B will enroll participants who are failing a current ARV regimen (HIV-1 RNA \> 1,000 copies/mL) to evaluate the safety, tolerability, and antiviral activity of EVG. The study consists of 4 age cohorts with each cohort including 2 parts (Part A and Part B) with the exception of the adolescent age cohort (Cohort 1: 12 to \< 18 years old) containing Part B only.

Interventions

DRUGEVG

Tablet (s) or tablet (s) for oral suspension (if unable to swallow) will be administered orally once daily

Background regimen may consist of the following ritonavir (RTV)-boosted PIs (PI/r): lopinavir/r (Kaletra), atazanavir/r, darunavir/r, tipranavir/r, or fosamprenavir/r. For participants \< 2 months old, only lopinavir/r is allowed. Use of additional antiretrovirals in background therapy may be allowed.

Participant flow

Recruitment details

Participants were enrolled at study sites in North America, Europe, Asia, and Africa. The first participant was screened on 26 August 2013. The last study visit occurred on 03 November 2017.

Pre-assignment details

48 participants were screened. The study was discontinued after enrollment of only Cohort 1, Part B and Cohort 2, Part A. The study close-out was triggered by the voluntary withdrawal of single-agent Vitekta® sale based solely on low utilization of the product, and was not a result of any ongoing or new safety issue.

Population: Participants in the Safety Analysis Set with available data were analyzed. Tanner Stage Assessments were not defined for participants with screening HIV-1 RNA \< 50 copies/mL because there were no postbaseline assessments scheduled in the protocol for these participants.

Tanner Stage Evaluation by Sex at Week 48

Tanner Stage (pubic hair and breasts for females; pubic hair and genitalia for males) at Week 48 visit was summarized using frequency count and percentage. Tanner Stages is a scale that defines physical measurements of development based on external primary and secondary sex characteristics. It was used in this study to assess pubertal development with values ranging from Stage 1 (pre-pubertal characteristics) to Stage 5 (adult or mature characteristics).

Time frame: Week 48

Population: Participants in the Safety Analysis Set with available data were analyzed. Tanner Stage Assessments were not defined for participants with screening HIV-1 RNA \< 50 copies/mL because there were no postbaseline assessments scheduled in the protocol for these participants.
