222 - How ICH Guidelines Are Organized: Understanding the Q, S, E, and M Series

In this episode of Let’s Combinate: Drugs + Devices, host Subhi Saadeh continues the Combinating with ICH series by breaking down how the International Council for Harmonisation (ICH) guidelines are organized and why that structure matters for drug and drug-device combination products.Subhi walks through the four main ICH guideline families, Quality (Q), Safety (S), Efficacy (E), and Multidisciplinary (M), and explains how each fits into the broader product lifecycle. The episode places particular emphasis on the Quality guidelines, which form the backbone of pharmaceutical development, manufacturing control strategies, and lifecycle management.Rather than a deep dive into requirements, this episode is designed to orient listeners to the full ICH landscape. It helps teams understand where different guidelines apply, who typically owns them, and how they collectively shape regulatory expectations.
