Evdokia,
One way to understand how the lower mRNA level in the finished product translates to efficacy would be to measure whether it affects significantly levels of protein expression. It could be that the level of antigenic protein expressed is not significantly affected. However, I donât know whether there is a test that would allow to predict impact on efficacy without clinical trial for comparability.

Dear Colleagues,
by the Europ
This email is for awareness and to flag an important comparability issue with the BioNTech
vaccine that needs to be addressed prior to approval.
Issue: A significant difference in %RNA integrity / truncated species has been observed
between the clinical batches ( ~ 78% mRNA integrity) based on which the Interim analysis
was performed and the proposed commercial batches (~ 55%).
The company claims that the efficacy of the drug product is dependent on the expression of
the delivered RNA, which requires a sufficiently intact RNA molecule. The root cause for
for the lower %RNA integrity at commercial batches has not yet been identified
Impact: The potential implications of this RNA integrity loss in commercial batches
compared to clinical ones in terms of both safety and efficacy are yet to be defined.
Whether or not the observed comparability issues could be a blocking point will depend on
the relevance of these observations to safety and efficacy and the company will be
requested to fully justify the lower %RNA integrity (and other differences noted).
Point for discussion will be whether the comparability issues can be solved only by Quality
data (additional functional/ in vitro biological data + available non-clinical) or that further
clinical data (bridging studies are/will be performed) will be needed. It is difficult to make
any projections on this
Way forward: This issue and other MO ( but in our view not blocking to a potential
approval) have been raised at ETF and are being discussed at BWP this week and in a TC
with FDA on Wednesday
With many thanks to Ton who’s is the Quality specialist for this vaccine together with Brian
looking after the chemical elements
Best regards

EPILOGUE:
The EMA covid-19 data leak, and what it tells us about mRNA instability
The British Medical Journal. BMJ 2021;372:n627
Leaked documents show that some early commercial batches of Pfizer-BioNTechâs covid-19 vaccine had lower than expected levels of intact mRNA, prompting wider questions about how to assess this novel vaccine platform.
EMA scientists tasked with ensuring manufacturing qualityâthe chemistry, manufacturing, and control aspects of Pfizerâs submission to the EMAâworried about âtruncated and modified mRNA species present in the finished product.â
An email identified âa significant difference in % RNA integrity/truncated speciesâ between the clinical batches and proposed commercial batchesâfrom around 78% to 55%. The root cause was unknown and the impact of this loss of RNA integrity on safety and efficacy of the vaccine was âyet to be defined,â the email said.
