Lonza’s Synaffix has secured two separate licensing deals with Boehringer Ingelheim and Japanese drugmaker Mitsubishi Tanabe Pharma for its antibody-drug conjugate tech.
The two “long-term” deals were announced Thursday. While details are sparse, including information on drug targets, Synaffix’s licensing deals tend to focus on cytotoxic ADCs for oncology despite some new interest in non-oncology targets, CEO Peter van de Sande told
Endpoints News
in an interview
.
Synaffix will give Mitsubishi access to its ADC tech for a single target.
Synaffix could receive up to $1.3 billion from Boehringer in milestone payments and is eligible to gain royalty payments from both companies depending on sales from future products. No upfront payments were disclosed.
Since Lonza’s $107 million (€100 million)
acquisition
of Synaffix in June 2023, it has boosted its headcount from around 30 employees to 60 and has “doubled down” on R&D, van de Sande said. Before joining Lonza, Synaffix
spun out
its own pharma subsidiary called Kivu Bioscience, which launched in October with three ADC assets and $92 million in hand.
For 2025, Synaffix is continuing to look for more partners and is open to both small and large collaborations, van de Sande said. The company is eager to secure more collaborations within the APAC region, as illustrated by the deal with Mitsubishi, he added. Van de Sande predicts there will still be a strong interest in using topoisomerase I inhibitors as payloads for ADCs.
With two new deals, Synaffix has a total of 17 publicly announced partnerships, which helps to raise its profile as a key ADC development partner. It secured at least
five licensing deals
in 2023. Boehringer and Mitsubishi join the likes of
Sotio Biotech
,
ABL Bio
and
Amgen
, who have all struck licensing deals with Synaffix.
As for Boehringer, the German pharma has recently honed in on boosting its cancer portfolio with its
$1.3 billion buy
of immuno-oncology Nerio Therapeutics in July last year, and by securing another ADC
licensing deal
with the Agency for Science, Technology and Research a month prior.
Mitsubishi has two oncology assets in its portfolio, which both use ADCs
licensed
from ADC Therapeutics from a partnership announced in 2022.
