After 25 years of trying to lead biopharma’s mRNA revolution across infectious diseases and cancer, German biotech CureVac made the surprise announcement Thursday morning that it would
exit to its rival and legal opponent BioNTech
.
The move, anticipated to close later this year, means CureVac will hand over its pipeline, people and operations to its main competitor even as litigation continues over its patented technology.
“At some stage, we started talking, but there was no process. It developed organically,” CureVac CEO Alexander Zehnder said in an interview with
Endpoints News
on Thursday afternoon.
“We came to, ‘Why don’t we make something together rather than fighting each other in court, right?'” Zehnder continued. “We saw a lot of complementary and different building blocks that we can bring to the table, some that they bring to the table. There’s very good chemistry always between the two companies, despite the litigation that we’re involved in.”
A patent infringement hearing between CureVac and BioNTech/Pfizer had been set for July 1 in Germany and will still take place as the deal goes through customary regulatory approvals, Zehnder said. CureVac alleged that BioNTech’s Covid-19 vaccine infringed some of its mRNA intellectual property.
A BioNTech spokesperson told Endpoints the company “generally” does “not comment on active litigation.”
If the case ended in CureVac’s favor, there was a risk
that BioNTech would have to dish out backdated royalties on the approximately $32 billion in global sales of the Covid-19 vaccine Comirnaty, Leerink Partners analyst Daina Graybosch wrote in a note to clients.
But the all-stock deal, valued at about $1.25 billion for CureVac, is “essentially an out-of-court settlement, in our view,” according to the analyst note.
CureVac had cash runway until at least 2028, meaning it was able to do the deal from a position of financial strength, rather than inking an exit with its “back against the wall,” Zehnder said. The company’s valuation has cratered, though, in the years after the investor furor that took place during the pandemic. CureVac was valued at
more than $9.8 billion
in its first day of public trading in August 2020, at the height of the Covid-19 vaccine race.
BioNTech CEO Uğur Şahin said in the deal announcement that the two companies have “complementary capabilities.” Zehnder also pointed to ways the companies’ technologies and pipelines could benefit from each other.
“We see a lot of combination potential for our pipeline with not just their mRNA pipeline but their broader pipeline, whether it’s bispecifics with the PD-L1xVEGF and so on and so forth” in infectious diseases, Zehnder said.
BioNTech has been building out its technology, pipeline and manufacturing footprint since 2020 via acquisitions, including deals with Biotheus, InstaDeep, PhagoMed Biopharma, Kite’s TCR platform and Neon Therapeutics, among others.
CureVac has a clinical-stage glioblastoma immunotherapy and near-term trials slated for certain forms of non-small cell lung cancer and urinary tract infection.
CureVac’s three central present-day R&D programs — in brain tumors, lung cancer and UTIs — are a small sliver of the broad ambitions CureVac had during its quarter-of-a-century life.
Founded in 2000, the Tübingen-based biotech signed a sprawling set of deals over the years with pharma giants like Johnson & Johnson, Boehringer Ingelheim, Eli Lilly, GSK and others to create cancer vaccines and other mRNA-based products. It also linked up with large nonprofits and global organizations like the Gates Foundation, IAVI, CEPI and others to create mRNA vaccines for infectious diseases.
Its profile, like that of its German peer BioNTech, skyrocketed in 2020 when the Covid-19 pandemic hit. The dawn of mRNA had arrived and both companies were on a mission to get a Covid-19 vaccine out to the world.
In the end, BioNTech and its partner Pfizer would succeed. CureVac tried to as well. It rushed to meet the dire moment, forging multiple manufacturing partnerships, lining up deals with European governments and collaborating with GSK. It raised more than
$600 million
in private funding in the summer of 2020 and then landed a $213 million IPO that August.
But CureVac would falter 11 months later in a pivotal trial of its candidate,
blaming pandemic variants
.
Since then, it’s adjusted its priorities. CureVac sold infectious disease vaccine candidates to GSK and has downsized in the past year. It had 983 employees at the end of 2024, per its annual report, but has about 700 staffers today, Zehnder said. Most work in Germany, but CureVac also has employees in Belgium, the Netherlands and the US.
“Will there be some synergies? For sure. But that was not a main driver for the deal and that will play out more, I would say ’27 and onwards, if at all. But of course, that’s at the discretion of BioNTech,” Zehnder said.
