Rare diseases are a global issue. While each rare disease impacts fewer than 50 people in 100,000, over 9000 have been identified.1 Taken in total, this means that 1 in 16 people are affected by a known rare disease. Of these, roughly 70-75% present in childhood, with 2 out 3 appearing before the child turns two. Some 30% will die before the age of 5.2
In this overview, we explore the clinical trials currently underway for rare pediatric disorders, examining their distribution by phase, status, country, and patient populations.
Despite the advent of new therapies, rare pediatrics continues to present significant challenges, necessitating detailed clinical studies to forge effective treatments.
Analysis of Citeline data reveals that rare pediatric conditions are the subject of roughly 4,500 active clinical trials, from early to late stages, reflecting a broad spectrum of research activity.3
Yearly analysis of rare pediatric trial start dates indicates growing research momentum, with an increase in trial starts each year.
Clinical trials for rare pediatrics extend across 147 countries, with a high concentration of studies the United States and China, illustrating the truly global nature of this research.
