Sanofi had been one of the world's biggest vaccine makers before
the pandemic, but the French firm was beaten by rivals BioNTech/Pfizer
and Moderna in developing mRNA shots against COVID-19.
Sanofi stopped trials of its own mRNA COVID-19 shot in
September, and is instead focusing on efforts with
GlaxoSmithKline to bring another COVID-19 vaccine candidate to
market based on the more conventional protein-based approach.
The French group said https://www.sanofi.com/en/our-covid-19-vaccine-candidates/mrna-vaccine
it would focus its mRNA resources on other infectious diseases
and therapeutics with strong unmet need.
Baidu will receive milestone payments when any mRNA-based
therapy or vaccine candidate discovered by Sanofi using its
algorithm enters clinical trials, said Huang Liang, a Baidu
scientist leading the project.
"The fact that this agreement includes milestone payments shows
that [Sanofi] has great confidence in bringing candidates
developed with Baidu algorithm into clinical trials and to the
market," Huang told Reuters. He declined to disclose the size of
the deal.
An mRNA-based vaccine contains mRNA sequence which instructs
human cells to produce proteins that can spur the immune system
into action.
Baidu's algorithm is designed to deliver a larger number of
optimised mRNA sequences and there are early signs that it could
be more suitable than standard algorithms in vaccine and
therapeutic drug development, Huang said.
Specifically regarding COVID-19 vaccine candidates, those
containing mRNA sequences generated by Baidu's algorithm were
more stable and appeared to require a smaller dosage than a
baseline shot based on a standard algorithm, according to lab
studies and animal tests https://arxiv.org/abs/2004.10177, which
haven't gone through peer-review.
