Introduction
• QbD (Quality by Design) is defined in the ICH guideline Q8(R2) http://www.fda.gov/downloads/Drugs/Guidances/ucm073507.pdf
• The ICH guidelines suggest to apply Quality by Design
principles in each step to eliminate risk or failures in drug
development processes
• Analytical method development for a drug is also a process
therefore quality principles from the ICH guideline should be
implemented
(ICH = International Conference of Harmonization of Technical Requirements
for Registration of Pharmaceuticals for Human Use, Founded in 1990 by an FDA initiative)

QbD Approach for Method Development
• Analytical QbD begins by defining goals (Analytical Target Profile, ATP)
and identifying potential method variables and responses
that affect method quality
• Statistical „Design of Experiments“ (DOE) has been applied to the
selected method variables leading to process and method
understanding and to create a list of critical method parameters
(CMPs- flow rate, temperature etc.) and critical method attributes
(CMAs- resolution, peak tailing)
• The experimentally measured responses were modeled to
determine the Design Space (defined in ICH Q8 (R2))
• A verified and validated method can be modified within the
Design Space to compensate any unforseen variables yet delivering
consistent results

Design Space: Definition
Combination and interaction of variables that
provides assurance of quality
Working within the design space is not considered
as a change
Movement out of the design space is considered a
change and would require regulatory approval
Design space is proposed by the applicant and is
subject to regulatory assessment and approval
(ICH Q8)

Approach # 1: Applying Isocratic Holding Steps
Results
• Results shows a low consitency
• Requires manual determination of the dwell volume/ isocratic hold
(in solvent delivery systems equipped with dampeners the dwell volume is pressure
dependent and variable)
• Requires modification of the methods
(should be avoided in validated environment,
but doesn’t require revalidation USP Chapter <621>)
