239 - ICH Q11 in 6 Minutes

In this episode, Subhi breaks down Q11 by focusing on three key sections: how the drug substance process is developed, where that process begins, and how it is controlled.

He places Q11 in context with Q7 for API GMP, Q8 for pharmaceutical development, Q9 for quality risk management, and Q10 for the pharmaceutical quality system. The episode covers Section 3 on manufacturing process development, Section 5 on starting materials, and Section 6 on control strategy beyond release testing.

In the next episode, Subhi will cover ICH Q12.
