The fundamental role of the pediatric investigation plan in European regulation
The Pediatric Investigation Plan now constitutes a cornerstone of pharmaceutical regulation in Europe concerning children’s safety. Introduced by Regulation (EC) No 1901/2006, the PIP requires pharmaceutical laboratories to define a clear strategy for testing new medicines in children. This requirement applies as soon as one wishes to develop a new treatment or extend the use of an already existing medicine to the pediatric population.
This framework ensures that clinical trials are specifically adapted to children’s particularities, which notably avoids the frequent mistake of considering children as “small adults.” For example, a medicine formulated for an adult may require a liquid or flavored administration to be effective and well tolerated in children, while taking into account their unique metabolisms.
The PIP covers different stages of development: pharmacokinetics study, evaluation of specific side effects, choice of doses and adapted pharmaceutical forms. Laboratories must submit their plan to the Pediatric Committee (PDCO) of the European Medicines Agency (EMA), which approves or requests modifications according to rigorous safety and efficacy criteria.
In practice, this obligation applies not only to new medicines, but also to new pediatric indications or changes in administration forms. However, laboratories may benefit from exemptions when the medicine holds no interest for children, but these are strictly controlled.
Thanks to this structured approach, the PIP promotes care truly tailored to the specific needs of children, reducing risks related to poorly calibrated treatments and improving their effectiveness. This legislative framework has profoundly transformed medical research, encouraging sustained collaboration between industry players and health institutions.
Major challenges in structuring pediatric clinical trials
The implementation of clinical trials in pediatrics faces significant challenges, quite different from those encountered in adults. One of the main obstacles is related to the diversity of ages and developmental stages: an infant, a toddler, and an adolescent each present distinct biological responses to treatments.
The Pediatric Investigation Plan must therefore include a fine segmentation of age groups, with adaptation of doses and pharmaceutical forms. Administrability is also a crucial issue; a flavored liquid formula is often preferred for young children, while adolescents can tolerate adapted tablets. These particularities play a decisive role in treatment adherence and therapeutic success.
Another major challenge concerns participant recruitment. The number of eligible pediatric patients is limited, requiring sometimes international multicenter coordination to ensure statistical robustness of results. Moreover, recruitment is governed by strong ethical requirements to guarantee the safety of child participants and fully respect the informed consent of parents or guardians.
The table below summarizes these challenges and their consequences in the development of medicines intended for children:
| 🌟 Challenge | 🔍 Description | 🎯 Key consequence |
|---|---|---|
| 👶 Limited recruitment | Small number of eligible children for trials | Extension of studies and need for international coordination |
| ⚖️ Ethical considerations | Enhanced protection of children during trials | Rigorous protocols and strict consents indispensable |
| 💊 Dose adaptation | Physiological variations according to age | Personalized dosages to avoid risks of overdose |
| 🧴 Adapted formulation | Need for pleasant and easy-to-administer forms | Improved adherence and tolerance rates |
A recent example illustrates these issues: the development of an asthma treatment in children by Johnson & Johnson. This project involved a complete adaptation of the aerosol formulation for daily usability from age 3. The PIP led to a rigorous protocol ensuring maximal tolerance while optimizing therapeutic effect.
Finally, the flexibility provided by the PIP sometimes allows postponements of pediatric studies, allowing to wait for solid adult data before involving children, thus reinforcing caution in pharmaceutical development.
The expertise of the PDCO in approval and monitoring of pediatric investigation plans
The Pediatric Committee (PDCO) of the European Medicines Agency acts as a guarantor of scientific and ethical excellence of pediatric clinical protocols. This multidisciplinary expert group includes medical and pharmaceutical specialists, family representatives, and lawyers, forming a pluralistic body.
When a laboratory submits a pediatric investigation plan, the PDCO conducts a detailed analysis of objectives, methods, targeted age groups, as well as safety aspects. This evaluation often takes the form of iterative exchanges aiming to clarify points to improve or adapt according to the latest scientific data.
PDCO decisions can range from direct approval of the PIP to requests for modifications, including granting waivers when a medicine is not relevant for pediatrics, or deferrals of certain study phases depending on results obtained in adults.
A recent innovation is the “stepwise PIP” initiative launched in 2023. It allows laboratories to initially submit a partial plan version before all necessary data is available for certain age groups. This method increases flexibility while ensuring comprehensive coverage of needs in the end.
This dynamic has encouraged constant collaboration between laboratories and authorities, thereby promoting continuous improvement of pediatric trials. For example, Pfizer regularly adapts its PIPs for infant vaccines based on PDCO feedback, ensuring optimal quality control throughout development.

Innovative strategies of pharmaceutical laboratories facing the pediatric investigation plan
The PIP is now a driver of innovation for pharmaceutical giants such as Sanofi, Roche, Novartis, or Johnson & Johnson. This regulatory constraint has encouraged teams to develop formulations specifically designed for children, integrating a human and practical dimension.
Among the implemented strategies are:
- 🌟 Development of dispersible tablets or pleasant syrups to facilitate daily administration.
- 🌟 Collaboration with parent associations to gather opinions on treatment acceptability.
- 🌟 Setting up pediatric focus groups to test tolerance and practicality of forms.
- 🌟 Constant dialogue with regulatory authorities to anticipate requirements and adjust protocols.
This approach is not limited to Europe: thanks to the harmonization of standards imposed by the PIP, validated pediatric medicines often benefit from faster international deployments, strengthening the competitiveness of laboratories.
Here are some examples illustrating these recent innovations:
| 🏢 Laboratory | 💡 Recent pediatric innovation | 🎯 Key issue related to the PIP |
|---|---|---|
| Sanofi | Preservative-free nasal spray, adapted for children | Acceptability and safety of use |
| Novartis | Pediatric formula for classic antidiabetic | Guarantee of safe long-term use |
| Roche | Prolonged-release subcutaneous injection | Optimization of infant dosage |
| Pfizer | Multivalent vaccine specifically designed for infants | Enhanced immunogenicity and better protection |
| Gilead | Oral antiviral with neutral taste and improved tolerance | Increased adherence and better tolerance |
This shift towards innovation reflects a strong commitment from laboratories to meet the expectations of families and health professionals, while respecting the high standards of medical regulation.
Family and professional engagement: an essential partnership for the success of the PIP
The Pediatric Investigation Plan goes beyond a mere administrative constraint to become a true human partnership. Involvement of parents, patients, and caregivers is now encouraged to enrich protocols and improve the quality of treatments.
Laboratories regularly organize user panels and discussion groups to collect experiences from children and families regarding medication administration. These feedbacks notably help correct difficulties related to acceptability or adherence, often unknown during preclinical phases.
European networks such as Enpr-EMA play an essential role in this collaboration, facilitating exchanges between researchers, physicians, and families at the international level. These close links contribute to more rigorous monitoring of pediatric pharmacovigilance and continuous protocol improvement.
This collective dynamic makes the PIP a powerful tool not only to guarantee safety and efficacy in children but also to build lasting trust among all stakeholders. By focusing research on the real needs of sick children, this method embodies the idea that health is first won through small acts and mutual understanding.
