QDbD is no longer a regulatory initiative; because QDbD is good development, QDbD is an industry initiative supported by regulators.

This course focuses on practical approaches to accelerated QDbD implementation, and it makes practical recommendations for realistic implementation of QDbD elements.

Participants will learn how to prioritize process parameters for screening designs, how to design robust processes using statistical design of experiments (DoE), how to bridge the bench and the commercial design spaces using mixing and scale-up calculations, how to quantify process risk, how to select suitable process analytical technology tools (PAT) and more.

Effective technology transfer to pilot and manufacturing plants is also discussed, including process validation in the QDbD.

Course Outline


  • Course objectives
  • QDbD in the context of the ICH guidelines for pharmaceutical manufacturing industry in the 21st century
  • Overview and definitions; how new is the QDbD concept?
  • Current status of QDbD implementation

ICH Guidelines

  • Risk-based, modern pharmaceutical manufacturing
  • Brief review of ICH Q8, ICH Q9, ICH Q10 and ICH Q11
  • ICH guidance covering questions and answers on Q8, Q9 and Q10 (2011)

QbD Methodology

  • The evolution of process understanding
  • Target Quality Profile, Critical Quality Attributes
  • Process parameters ranking methods

Screening the Experimental Space

  • Advantages of design of experiments (DoE) vs. one factor at a time approaches
  • The importance of pre-DoE experimentation and planning
  • Factors, ranges, number of le vels, responses
  • Design quality: resolution and efficiency
  • Commercial DoE software (sometimes a second opinion can be useful)

Robust Process Design

  • Key and Critical Process Parameters
  • Response surface methodology, process optimization (at small or intermediate scale) to define a design space
  • Strategies in defining a design space
  • Process validation in the QDbD paradigm
  • Control strategy
Risk Analysis

  • Semi-quantitative risk estimates
  • Process risk quantification using Monte Carlo simulations

Pharmaceutical Process Scale-Up

  • Design space and scale-up factors
  • Scale-up theory; scaling-up by scaling-down
  • Mixing and scale-up calculations in turbulent regime, mixing times calculations (micromixing, mesomixing, and macromixing)
  • Effective scale-up of heterogeneous solid-liquid processes (catalytic, API crystallization process scale-up)
  • Process understanding for effective technology transfer
  • Advantages and challenges of continuous chemical processing

Process Analytical Technology

  • PAT principles, levels of PAT implementation
  • Control strategies
  • Real time release

Regulatory Advantages

  • QDbD submissions

I think everyone should be exposed to the principles of QbD because this is the direction of the business. Dr Zlota presented the information in a way that was easy to understand.

It was very interesting! A very good introduction to QbD for me. Great!


Great DoE introduction in the QbD environment.
