In pediatric drug research, researchers face many challenges, such as small number of pediatric patients, large individual differences, strict ethical requirements, etc. Traditional research designs are often difficult to cope with. Adaptive design can flexibly adjust the research route according to real-time data during the research process, helping researchers to conduct clinical research more efficiently and safely. Adaptive design refers to a design that modifies one or more aspects of a clinical trial based on accumulated data based on a pre-set plan after the start of a clinical trial. Common adaptive designs include: (1) Re-estimation of sample size: Based on the interim analysis results, the initially set sample size is adjusted to avoid insufficient or excessive sample size. (2) Enrichment design: based on clinical characteristics or biomarkers, screen out patient groups that are more likely to benefit from treatment, explore indication populations, and improve research efficiency. (3) Dose adjustment: According to the safety and efficacy data, adjust the dose administered to subsequent patients to find the best dose range. (4) Adjustment of treatment grouping: According to the results of interim analysis, terminate ineffective or harmful treatment groups early, or reassign patients to more effective treatment groups. Adaptive design is still in development, and combined with the needs of researchers, more innovative adaptive design methods will emerge to meet the needs of different types of pediatric research.
