Why Science? | ICH M8 eCTD and Structured Regulatory Submissions

The CTD provides a harmonised organisation for quality, nonclinical and clinical information in marketing applications. eCTD adds the technical message, metadata and life-cycle mechanisms needed to transmit and maintain that organised content electronically.

The CTD provides a harmonised organisation for quality, nonclinical and clinical information in marketing applications. eCTD adds the technical message, metadata and life-cycle mechanisms needed to transmit and maintain that organised content electronically. Keep this boundary visible: Technical validation cannot establish scientific adequacy.

A strong science note separates observation from interpretation. Trace m8 carries the common technical document electronically from source report through module, metadata, submission unit, validation and regulatory receipt. Record the source, version or date, population or device context, method, result and one uncertainty. If the official record does not show a field, write “not shown” instead of filling the gap from memory.
