Christine,

 

As I am teaching a course on Stability Storage Programs, I was able to
locate guides that explicitly address the stability testing at several
positions.

 

ICH Q5C (See below!) is explicit.  A WHO guide (See below!) on Vaccines also
requires two positions. The Asean Guideline on Stability Study of Drug
Product addresses several times this point for several types of drug
products.

 

I hope this helps!

STABILITY TESTING OF BIOTECHNOLOGICAL/BIOLOGICAL PRODUCTS

Q5C

 

6.5. Container/Closure

Changes in the quality of the product may occur due to the interactions
between the formulated biotechnological/biological product and
container/closure. Where the lack of interactions cannot be excluded in
liquid products (other than sealed ampoules), stability studies should
include samples maintained in the inverted or horizontal position (i.e., in
contact with the closure), as well as in the upright position, to determine
the effects of the closure on product quality.

 

 

 

GUIDELINES ON STABILITY EVALUATION

OF VACCINES, WHO/BS/06.2049 - Final

 

5.4.2. Vaccine presentation, container and closure system

In addition to the data on stability of the final formulation, other factors
that may affect

vaccine stability during its use should also be tested in the stability
study. Potential interactions

between the vaccine and container and closure system are particularly
important for vaccines in

liquid form. The impact of the closure system on vaccine stability and
quality in general should

be tested by exposing and maintaining samples into different positions
during a certain period of

time. These positions should mimic possible situations that may occur during
the transport and

storage and that provide contact between vaccine and the closure system
(upright; horizontal or

inverted position).
