• 215 - Why Aren’t Technical People Leading Drug-Device Audits?

  In this episode of Let’s Combinate, Subhi Saadeh breaks down why more engineers in pharma, medical devices, and combination products should seriously consider becoming auditors. Sparked by a question at a PDA conference: “Why don’t more technical people lead audits?” This episode explores the gap between technical expertise and true audit competency.Subhi explains how engineers who combine their technical background with audit training often become the most effective auditors. They gain a system-level perspective, understand how design decisions ripple through the QMS, and can identify systemic root causes that others overlook. He also clears up common misconceptions about auditing, including the idea that it’s just paperwork or checklist work, and reframes it as one of the fastest ways to build regulatory fluency, strengthen quality systems understanding, and expand career versatility across industries.The episode closes with practical steps for how engineers can get started: shadowing internal audits, learning audit frameworks and methodologies, taking formal training, and seeking mentorship from experienced auditors.Timestamps:00:00 – Why Engineers Should Consider Auditing01:10 – How Auditing Expands Technical Perspective05:26 – Misconceptions & Why Engineers Avoid Auditing11:25 – How to Start Your Audit Journey13:27 – Final Thoughts: Seeing the System, Not Just the SpecSubhi Saadeh is the Founder and Principal of Let’s Combinate BioWorks and the host of Let’s Combinate: Drugs + Devices.

  In this episode of Let’s Combinate: Drugs + Devices, host Subhi Saadeh welcomes Mark Kramer, the founding director of FDA’s Office of Combination Products (OCP). Mark takes us on a deep dive into the history of how combination products have been regulated in the U.S., starting with the Safe Medical Devices Act of 1990 and how the process evolved into the formation of OCP in 2002.We explore questions such as: What challenges did industry and the FDA face in the early days of combination products? How did the “Request for Designation” process come about, and how is regulatory identity determined? What is the “Primary Mode of Action” (PMOA) rule and why does it matter? How do user fees, cross-center coordination, and post-market regulations shape how combination products get to market and are monitored? Mark also highlights current regulatory gapssuch as cross-labeling and site registration issues that continue to impact developers.Whether you’re working in med-tech, pharma, or regulatory affairs, this episode offers historical perspective, technical insights, and strategic take-aways for navigating the combination-product space.
