After initially promising more than $1 billion in biobucks to its partner Biotheus for a single drug, BioNTech is now buying out all of the China-based company for $800 million in cash and as much as $150 million more in milestones.
In addition to the PD-L1/VEGF drug the companies were already partnered on, Wednesday’s deal will give BioNTech multiple clinical-stage drugs, an R&D hub, an operational biologics manufacturing site in China, and 300 employees.
“We were looking for several years for the next-generation immune modulator. We believe we have found now the molecule that we were seeking,” CEO Uğur Şahin said in an interview with
Endpoints News
.
The companies struck their initial partnership a year ago, built around
BNT327
/PM8002, a bispecific antibody going after PD-L1/VEGF. The drug will enter registrational trials later this year. Additional studies next year will test it in combination with antibody-drug conjugates.
By acquiring the six-year-old startup, BioNTech can speed up the development of multiple cancer drugs, have more control over the direction of the lead asset in the hot PD-L1/VEGF space, and gain access to a clinical team that can help the German drugmaker run more trials in China, Şahin said.
BioNTech started in cancer, but vaulted into the global spotlight because of its Covid-19 vaccine. It’s invested heavily to
make oncology its future
, including several antibody-drug conjugates and an mRNA-based cancer vaccine to be used with checkpoint therapies.
The PD-L1/VEGF space has become closely watched within cancer drug development thanks to Summit and Akeso’s claims in September that their drug, ivonescimab,
beat Keytruda
in a head-to-head study conducted in China. Former Seagen CEO David Epstein is also betting on the field with a preclinical PD-1/VEGF biotech known as
Ottimo Pharma
.
Şahin has described BNT327 as being “
further enriched
in the tumor microenvironment” than ivonescimab because of its PD-L1-directed approach, rather than honing in on PD-1.
BioNTech will also go head-to-head with Keytruda, Şahin said in the interview. Merck’s medicine is the world’s
top-selling treatment
and has been approved across more than 15 different tumor types.
“At the end of the day, there is no way around this,” Şahin said of the need to battle Keytruda head-on.
But if it works out, the deal could be seen as a steal: Summit, for example, trades at a market value of around $15 billion, largely based around its success with its PD-1/VEGF drug.
The deal comes 12 months after BioNTech said it could dish out
more than $1 billion
in biobucks to Biotheus to partner on the drug. The pair also had a
pact for other antibodies
. The deal will give BioNTech worldwide rights to the compound; Biotheus previously still owned the China rights.
“From the financial standpoint, it is more or less paying the milestones earlier. From the value structure, it’s about getting better control of the assets, increasing the potential for additional clinical candidates,” Şahin said.
Biotheus will also deliver to BioNTech a broad pipeline of clinical-stage antibodies, including work in TIGIT and Claudin18.2, and preclinical ADCs, which have become one of the buzziest drug approaches in oncology R&D. Biotheus has also said it’s conducting research in inflammatory and autoimmune diseases.
It also gives BioNTech a foothold in China, where it has ADC deals with
MediLink
and
Duality
Biologics.
“We are thrilled to deepen our bond with BioNTech,” Biotheus CEO Xiaolin Liu said in a statement. “We share the goal of advancing the development of BNT327/PM8002 for future combination therapies in the fight against cancer.”
Biotheus last disclosed a $100 million Series D in March 2021,
according
to
ChinaBio Today
. General Atlantic, IDG Capital, Kunlun Capital and others have invested in the startup,
according
to Biotheus. Şahin told Endpoints he doesn’t know how much Biotheus has raised to date.
The Biotheus acquisition is BioNTech’s biggest deal so far, Şahin said.
It has made only a few acquisitions in its history, including
$440 million
for
AI partner
InstaDeep. Flush with cash from its Pfizer-partnered Covid vaccine, BioNTech has a hefty balance sheet and ended last quarter with
€17.8 billion
(about $18.8 billion) in cash, equivalents and security investments.
After a “major pipeline reshaping” last year, the company wanted to focus on its existing drugs and partnerships, chief medical officer and co-founder
Özlem Türeci told
Endpoints News
on the sidelines of this year’s American Society of Clinical Oncology meeting.
“We are a very scientific company, which, however, does not have this ‘not invented here’ complex,” Türeci said in the June interview. “We are very curious about technological breakthroughs and bits and pieces, which can be implemented into a broader technology space.”
The deal is expected to close in the first quarter of next year.
