Abstract
Background Placebo-controlled trials are the most rigorous method of evaluating the safety and efcacy of investigational
treatments, yet the use of a placebo control in pediatric drug development is challenging and potentially controversial.
Regulations provide additional protections for children participating in human subject research and limit the amount of risk
to which children may be exposed without beneft (21 CFR 50, subpart D, Additional Safeguards for Children in Clinical
Investigations). The objective of this paper is to describe the US Food and Drug Administration (FDA) experience with
placebo-controlled trials conducted as part of pediatric drug development programs including compliance with 21 CFR 50,
subpart D.
Methods Pediatric drug development programs conducted under the Best Pharmaceuticals for Children Act (BPCA) or the
Pediatric Research Equity Act (PREA) between 2012 and 2018 were reviewed. Trials that utilized a placebo control were
identifed and trial characteristics and risk mitigation strategies were extracted from publicly available sources.
Results During this time frame, a total of 266 products were studied under pediatric product development initiatives. Of
those, 67 products (25%) were studied in 96 individual placebo-controlled trials in pediatric patients. The majority of these
studies included approaches to minimize risk to children in the placebo arm, including 49 trials that utilized placebo as an
add-on to known efective therapy for the disease and 48 trials that included rescue therapy in the study protocol.
Conclusions When designed and conducted appropriately, placebo-controlled trials meet requirements under current US
federal regulations for the protection of children in research.

Introduction
The type of control utilized in a clinical trial afects the
inferences that can be drawn from the trial and the degree to
which bias in study conduct and analysis can be minimized
[1]. Placebo-controlled trials are the most rigorous method
of evaluating the safety and efcacy of an investigational
treatment. Participants randomized to a placebo group are
not always untreated; in many placebo-controlled trials, the
investigational treatment and placebo are each added to a
standard background therapy (i.e., add-on studies).
Placebo-controlled trials ofer several advantages, including
(i) measurement of absolute efcacy and safety, (ii) increased
efficiency enabling a reduced sample size, (iii) ability to
