201147: a Phase IIIb, Randomized, Open-label Study of the Safety, Efficacy, and Tolerability of Switching to a Fixed-dose Combination of Abacavir/Dolutegravir/ Lamivudine From Current Antiretroviral Regimen Compared With Continuation of the Current Antiretroviral Regimen in HIV-1 Infected Adults Who Are Virologically Suppressed, The STRIIVING Study.

Surveillance Monitoring for ART Toxicities Study in HIV Uninfected Children Born to HIV Infected Women
Many antiretroviral therapy (ART) medications given to a pregnant woman cross the placenta and can be detected in the amniotic fluid and cord blood resulting in substantial fetal exposure. Therefore, there is concern about toxicity of the drugs in the fetus and infant. It is noteworthy that none of the currently approved ART medications for the prevention of maternal to fetal transmission of HIV are in Food and Drug Administration (FDA) Pregnancy Category A (no fetal risk ascertained in adequately controlled human studies). Thus, there is continued need to examine the toxicity of ART in HIV transmission prevention for the short-term toxicity of newer agents and combinations as well as the unanswered questions of longer term toxicity and subtle adverse effects. The study will use a registry approach to conduct active surveillance among children < 12 years of age at enrollment. Occurrences of abnormalities from ART exposure in utero and/or in the first two months of life will be sought in multiple domains, including metabolic, growth, cardiac, neurologic, neurodevelopmental, behavior, language, and hearing. Clinical and laboratory data will be examined for abnormalities through a hierarchy of evaluations: adverse events (AE) will be identified → selected AEs will trigger predefined additional evaluations → significant observations will be defined as cases → a pattern of significant study-wide cases will be defined as signals. The incidence of these events of interest will be monitored over time and by ART regimen, and compared with historical data that may be suggestive of a signal. Some signals may be testable using existing and/or previously collected data, while other signals may indicate the need for additional hypothesis-driven studies outside of SMARTT. The objectives of SMARTT are: 1. To estimate the occurrence of potential ART-related toxicities through an ongoing surveillance system among HIV-uninfected children born to mothers with HIV infection with and without exposure to ART in utero and/or in the first two months of life and compare the occurrences of these outcomes with other sources of data as well as by ART exposures; and 2. To actively encourage hypothesis-driven studies to confirm that the signals are due to ART exposure in utero and/or in the first two months of life. Note that the full design and execution of these studies may be beyond the scope of the SMARTT study but will be facilitated by SMARTT. The specific aims of SMARTT are: 1. To create a Static Surveillance Cohort to extend domain-specific data collection in children either 1) previously enrolled in any of the approved studies for enrollment into SMARTT; 2) previously enrolled in another pediatric HIV/AIDS cohort study with SMARTT Protocol Chair approval, or 3) not previously enrolled in an approved study but with equivalent data available in the medical record; 2. To create a Dynamic Surveillance Cohort to examine domain-specific data of children newly exposed to ART in utero and/or in the first two months of life; 3. To create a Young Adult Cohort to study long-term outcomes in SMARTT participants formerly enrolled in the Static and Dynamic cohorts. 4. To identify a set of "triggers" for each domain that define a "signal" of possible ART toxicity and compare the occurrence of these signals with previously collected data and by ART exposure; and 5. To encourage and facilitate the development of hypothesis-driven studies to evaluate whether a "signal" is the result of ART exposure in utero and/or in the first two months of life.

Very Early Intensive Treatment of HIV-Infected Infants to Achieve HIV Remission: A Phase I/II Proof of Concept Study
The purpose of this study is to explore the effects of early intensive antiretroviral therapy (ART) on achieving HIV remission (HIV RNA below the limit of detection of the assay) among HIV-infected infants. The study will enroll two cohorts. Cohort 1 will include infants at high risk for in utero HIV infection. Cohort 2 will include in utero HIV-infected, ART-started infants. Three early intensive therapy regimens will be assessed. Regimen 1L will include 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus nevirapine (NVP) plus lopinavir/ritonavir (LPV/r). Regimen 2R will include 2 NRTIs plus NVP plus raltegravir (RAL). Regimen 2RV will include 2 NRTIs plus NVP plus RAL plus VRC01 monoclonal antibody. The study will be conducted in four steps. In Step 1, Cohort 1 infants will be enrolled for evaluation of HIV infection and initiation of early intensive therapy within 48 hours of birth. Infants in whom in utero HIV infection is excluded will switch from the study regimen to standard perinatal prophylaxis per local guidelines within two weeks; these infants will continue in Step 1 safety monitoring for two additional weeks, undergo final HIV testing at approximately 12 weeks of age, and then exit the study. Infants in whom in utero HIV infection is confirmed will enter Step 2 at least two weeks after enrollment in Step 1. In Step 2, Cohort 1 infants identified with in utero HIV infection and Cohort 2 infants will receive the study regimen for up to 192 weeks. Beginning at Step 2 Week 84, children who achieved HIV RNA suppression by Week 24, and maintained suppression thereafter, with no HIV RNA detected at or after Week 48, will be evaluated for possible treatment cessation. In Step 3, children in Step 2 who meet criteria for treatment cessation will stop ART, and be closely monitored for viral rebound for up to five years. In Step 4, children who experience viral rebound in Step 3 will re-start ART, and be closely monitored for viral re-suppression on ART until five years of age or six months after re-suppression, whichever is later. HIV-uninfected infants will be followed for 12 weeks. HIV-infected infants will be followed for up to 192 weeks in Step 2 (on ART); those entering Step 3 will be followed for primary endpoint ascertainment at 48 weeks and for up to a total of five years (off ART) in this step.
