Background

• Pfizer Goal– “Top-tier biotherapeutics company”

• But supporting informatics infrastructure had many gaps

• Biomolecules Team Goal– Make biomolecules “first-class citizens” of the informatics tool

portfolio• Working on therapeutic oligonucleotides since 2008• Build on this work to support additional entities for

– Registration– Visualization– Analysis and design– Workflows

• HELM is a result of this initiative

HELM Phase 2 - Ambiguity

Systems need to handle molecules that are not always fully defined

• A design for the representation of ambiguity has been drafted

• RFP Issued and bid selected• Development work starting soon

IDMP

The implementation guide for ISO 11238: Health Informatics - Identification of medicinal products will include HELM as an acceptable format.

Working with the FDA to include HELM as a format within GInAS.• GInAS will provide a common global identifier for all

substances used in medicinal products or active substances under clinical investigation
