Boehringer Ingelheim GmbH’s start to the new year includes two fresh deals across two continents. BI struck one deal with Kunshan, China-based Suzhou Ribo Life Science Co. Ltd. and its Mölndal, Sweden-based subsidiary, Ribocure Pharmaceuticals AB, to develop small interfering RNA (siRNA) treatments for nonalcoholic or metabolic dysfunction-associated steatohepatitis. It struck a second deal with San Francisco-based 3T Biosciences Inc. to develop cancer immunotherapies, which builds on an earlier collaboration formed last year. Combined, the two deals are worth more than $2.5 billion.

GSK plc is plunking down $1 billion cash to take over Aiolos Bio Inc., with the promise of as much as $400 million in regulatory milestone payments along with tiered royalties. The deal gives London-based GSK asthma candidate AIO-001, a phase II-ready, long-acting antibody that binds to the human thymic stromal lymphopoietin (TSLP) ligand to inhibit TSLP signaling and relieve inflammation. GSK said AIO-001 could redefine the standard of care in asthma via the prospect of dosing every six months.
