SHIELD study: a multicenter, open-label, single-arm trial to evaluate the safety, pharmacokinetics and antiviral activity of fostemsavir in combination with optimized background therapy (OBT) in children and adolescents with HIV who are failing their current combination antiretroviral therapy (cART) and have dual- or triple-class antiretroviral (ARV) resistance.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundMulti-drug resistant HIV-1 is a growing global concern in children, highlighting the need for new antiretroviral drugs. Fostemsavir, recently approved for adults with multi-drug resistant HIV-1 and limited treatment options, has not yet been evaluated in the pediatric population. The SHEILD protocol was developed to assess this missing research gap.

methodsThe SHIELD study is a multicenter, phase I/II, open-label, single-arm trial evaluates the safety, pharmacokinetics and antiviral activity of fostemsavir in combination with optimized background therapy (OBT) in children and adolescents with HIV-1 who are failing their current combination antiretroviral therapy and have at least dual-class resistance. Participants will receive weight-based fostemsavir dosing: 400 mg twice daily for participants ≥20 to < 35 kg, and 600 mg twice daily for those ≥35 kg. It is planned to recruit at least 28 evaluable participants, including at least 8 participants under 12 years old weighing ≥20 kg to < 35 kg, of whom at least 4 must weigh ≥20 to < 25 kg. Participants will be treated for a minimum of 24 weeks, with safety follow-up continuing to 48 weeks. It is planned that those children benefiting from fostemsavir treatment may continue for up to 156 weeks to assess long-term safety. DISCUSSION: This registrational trial will generate data supporting the approval of fostemsavir for pediatric patients aged ≥6 years and weighing ≥20 kg.
