Modernizing a pediatric "excipient" database with AI — the safety of what is not the active ingredient (NIH, $2.67M)
The U.S. National Institutes of Health awarded Advanced Bioscience Laboratories about $2.67 million to modernize STEP, a database on excipients in medicines for children. The work integrates and makes the data queryable using AI and machine learning. Its subject is not the active ingredient but everything else in the formulation.

Contract scope (original)
SCALABLE, RELIABLE ARTIFICIAL INTELLIGENCE (AI)/MACHINE LEARNING (ML)- DRIVEN INTEGRATION AND INTERROGATION TO MODERNIZE THE STEP PEDIATRIC EXCIPIENT DATABASE
Key points
- NIH awarded Advanced Bioscience Laboratories about $2.67 million ($2,674,036).
- The subject is modernizing STEP, a pediatric excipient database, through AI/ML-driven integration and interrogation.
- Excipients are everything other than the active ingredient — bulking agents, sweeteners, flavors, colorants, preservatives, and more.
- In children, intake per unit of body weight and metabolic capacity differ, so adult data cannot simply be carried across.
- Period August 1, 2026 to July 31, 2027. Award type DELIVERY ORDER under parent contract 75N93023D00001.
- Excipients carry no therapeutic effect and are left until later in safety debate, while still entering the body.
1What an excipient is
A tablet or a syrup is not made of active ingredient alone. Bulking agents that hold a form, sweeteners and flavors that make it palatable, colorants, preservatives, components that tune how it dissolves — everything that is not the active ingredient is collectively the excipients. Because excipients carry no therapeutic action, safety discussion tends to reach them last. But they enter the body all the same, and they have effects.
2Why children make this acute
Giving an adult medicine to a child is not simply a matter of reducing the dose. Intake per unit of body weight rises for some components, and metabolic capacity differs from an adult's. Liquid formulations made to be swallowed can carry excipients an adult tablet never contains. Yet safety data on excipients in children has never been organized to the degree the active ingredients have.
A database such as STEP — Safety and Toxicity of Excipients for Paediatrics — exists to close that gap.
3What "integration and interrogation" means here
The scope names integration and interrogation. Safety information about excipients is scattered across sources of different shapes: papers, regulatory documents, toxicology reports. The same substance often appears under different names. Bringing all of it into a form a machine can work with, and into a state where it can answer questions, is what this contract reads as.
As a use of AI, it is placed on retrieving knowledge that already exists rather than on discovering anything new.
4The asymmetry between active ingredient and excipient
Debate on drug safety gathers around the active ingredient. Excipients sit in the same medicine and have been treated differently.
Giving an adult medicine to a child is not settled by reducing the dose. Some components rise in intake relative to body weight, and metabolic capacity differs from an adult's. A database such as STEP is needed to fill that gap. The use of AI here lies less in making discoveries than in making existing knowledge retrievable.
Why it matters
Organizing safety data is an investment whose results are hard to see, yet it is the foundation formulation design rests on. Integrating scattered sources into a machine-readable form is a use of AI aimed at retrievability rather than discovery, so the honest measure of success is whether the material can now be queried rather than what new fact emerged. Public procurement data lets this kind of foundational work be tracked as well.
