Insights
Children in drug trials face moderate to severe adverse drug reactions (ADRs). Establishing data safety monitoring boards (DSMBs) is crucial for ensuring child participant safety in clinical research.
Area of Science:
- Pediatric Pharmacology
- Clinical Trial Safety
- Drug Development
Background:
- Increasing participation of children in drug trials necessitates robust safety measures.
- Children in clinical trials are susceptible to moderate and severe adverse drug reactions (ADRs).
- A significant gap exists in the implementation of data safety monitoring boards (DSMBs) for paediatric drug trials.
Purpose of the Study:
- To analyze the incidence and severity of ADRs in paediatric drug randomized controlled trials (RCTs).
- To assess the presence and impact of independent data safety monitoring boards (DSMBs) in these trials.
Main Methods:
- Systematic review of paediatric drug RCTs published in 2007.
- Classification and severity assessment of reported adverse events (AEs) to identify ADRs.
- Examination of trial reports for the presence of independent DSMBs.
Main Results:
- Over half of the analyzed RCTs (305) reported ADRs, with 66 (11%) being severe and 79 (14%) moderate.
- Serious adverse events, including mortality, were reported in 36% of trials.
- Only 12% of RCTs reported having a DSMB, though these boards did intervene to terminate trials or alter protocols.
Conclusions:
- Paediatric participants in drug RCTs experience a substantial number and variety of ADRs.
- The implementation of DSMBs is essential for safeguarding children in clinical drug trials.
- DSMBs play a vital role in monitoring trial safety and can necessitate protocol changes or early termination.
Background:
There is now greater involvement of children in drug trials to ensure that paediatric medicines are supported by sound scientific evidence. The safety of the participating children is of paramount importance. Previous research shows that these children can suffer moderate and severe adverse drug reactions (ADRs) in clinical trials, yet very few of the trials designated a data safety monitoring board (DSMB) to oversee the trial.
Methods:
Safety data from a systematic review of paediatric drug randomised controlled trials (RCTs) published in 2007 were analysed. All reported adverse events (AEs) were classified and assessed to determine whether an ADR had been experienced. ADRs were then categorised according to severity. Each trial report was examined as to whether an independent DSMB was in place.
Results:
Of the 582 paediatric drug RCTs analysed, 210 (36%) reported that a serious AE had occurred, and in 15% mortality was reported. ADRs were detected in more than half of the RCTs (305); 66 (11%) were severe, and 79 (14%) were moderate. Severe ADRs involved a wide range of organ systems and were frequently associated with cytotoxic drugs, antiparasitics, anticonvulsants and psychotropic drugs. Two RCTs reported significantly higher mortality rates in the treatment group. Only 69 (12%) of the RCTs stated there was a DSMB. DSMBs terminated five RCTs and changed the protocol in one.
Conclusions:
Children participating in drug RCTs experience a significant amount and a wide range of ADRs. DSMBs are needed to ensure the safety of paediatric participants in clinical drug trials.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
