January 2001
DPTC to CCWG
Find a way to avoid unnecessary stability
testing if the water uptake of a new package
is the same as or better than the existing
package.
Testing to be carried out at 40o C/75% RH
and at RT/60% RH

December 2001
Meeting of CCWG
• Focus on supporting Post Approval
Packaging Change (PACPAC)
• Create a definition of “equivalence” for
container closure systems
• Focus on Solid Oral Dosage forms (80%
of marketed drug products)
• Formed 4 committees to review:
5
December 2001
Meeting of CCWG
• Four committees to review:
Definitions of equivalence
Test methods for WVTR
Test methods for light transmission - dropped
Test methods for seal integrity - dropped
6
December 2002
CCWG established five research objectives
• Establish clear definition of “equivalence”
• Develop a method of test; accuracy and
sensitivity of current USP <671> are
questionable
• Achieve differentiation among high barrier
packages
7
December 2002 (Continued)
Research objectives (continued)
• Utilize WVTR/unit – problem with volume
for bottles vs dosage unit for blisters
This one became first priority
• Define when, during testing, WVTR steady
state is reached
8
December 2002: Decision Made
•
to design an experiment that would meet
the five research objectives.
– Data mining was not working.
•
•
Began DOE for bottle and blister WVTR.
WVTR/unit remains first priority.

Jan-Feb 2005 (Slide 1 of 3)
Published in Pharmacopeial Forum, vol
31(1)
“Basis for Using Moisture Vapor
Transmission Rate per Unit Product in
the Evaluation of Moisture-Barrier
Equivalence of Primary Packages for
Solid Oral Dosage Forms”
10
Jan-Feb 2005 (Slide 2 of 3)
Three points made in the paper
1. MVTR/unit is the critical parameter for
equivalence
2. Once an equivalent range is
established by stability test and
MVTR/unit, then a substitute barrier
package is an equivalent barrier if the
MVTR/unit is within the qualified
range
11
Jan-Feb 2005 (Slide 3 of 3)
Three points made in the paper
3. A method with increased sensitivity is
required in order to satisfy point 2.
12
September, 2006
• PQRI bottle protocol finalized.
• Experiment under way in four
laboratories to measure WVTR of bottles
and blisters
• DOE included measure of variation within
lab and between lab

June 7, 2011 Meeting of CCWG
1. Started planning to publish an article to
summarize and publicize:
(a) WVTR/unit concept
(b) bottle and blister studies
(c) ASTM Method
22
June 7, 2011 Meeting of CCWG
(Continued)
(d) how to apply these concepts and
methods to reduce regulatory burden
for changes to container closure
systems.
We will publish in a scientific journal and a
trade journal
