Investment in the fourth quarter of 2022 was dismal in Asia Pacific, as the global venture community focused on preserving capital. And the region faced other challenges throughout the year, as leaders in Australia and across Asia became acutely aware of the vulnerabilities in their supply chains. But the year also saw some big deals and collaborations involving companies across Asia Pacific, along with advances in regenerative and digital medicine.

South Korea’s Legochem Bioscience Inc. inked a licensing deal with Amgen Inc. on Dec. 23 for five undisclosed antibody drug conjugate (ADC) targets worth up to ₩1.6 trillion (US$1.24 billion). Under the terms of the deal, Legochem will out-license global rights to Amgen for five undisclosed ADC targets and will receive an undisclosed up-front payment as well as development milestones and sales royalties. The companies did not disclose additional details.

Two deals for antibody-drug conjugates inked since May between Merck & Co. Inc. and Sichuan Kelun-Biotech Pharmaceutical Co. Ltd. have blossomed eight months later into the year’s biggest agreement, one that could bring Kelun-Biotech up to $9.3 billion in development, regulatory and sales milestones. The exclusive license and collaboration deal has Merck paying an up-front $175 million to Kelun-Biotech plus promising to make an equity investment in the Sichuan, China-based company.

Innovent Biologics Inc. has in-licensed LG Chem Ltd.’s tigulixostat (LC-350189), a late-stage non-purine xanthine oxidase inhibitor for managing chronic hyperuricemia in patients with gout, in a deal worth up to $95 million.

Sosei Heptares and Eli Lilly and Co. have signed a potential $731 million deal to discover, develop and commercialize small molecules that modulate G protein-coupled receptor (GPCR) targets associated with diabetes and metabolic diseases.

Pfizer Inc. has acquired rights to respiratory syncytial virus (RSV) drug candidate sisunatovir from Lianbio Co. Ltd. in a deal worth up to $155 million covering development and commercialization rights in mainland China, Hong Kong, Macau and Singapore. With this agreement, Pfizer now holds global development and commercialization rights to the candidate, an orally administered fusion inhibitor is designed to block RSV replication by inhibiting F-mediated fusion with the host cell.

Sotyktu (deucravacitinib), the tyrosine kinase 2 (TYK2) inhibitor for psoriasis from Bristol Myers Squibb Co., is “a good first-in-class” drug, said Nimbus Therapeutics LLC CEO Jeb Keiper, but his firm may have the best in class, ready for phase III trials. Takeda Pharmaceutical Co. Ltd. apparently believes so. The company has agreed to pay $4 billion up front and pledge as much as $2 billion more in potential milestone payments to acquire Nimbus’s wholly owned subsidiary, Nimbus Lakshmi Inc., thereby bringing aboard the TYK2 prospect called NDI-034858.

Full-Life Technologies Ltd. reported that it will acquire Focus-X Therapeutics Inc. to expand its radiopharmaceutical oncology therapy pipeline in a deal worth up to $245 million.

In a massive deal that is one of the year’s biggest, Akeso Inc. signed a collaboration and license deal with Summit Therapeutics Inc. to out-license its bispecific antibody, ivonescimab (AK-112), for development and commercialization in the U.S., Canada, Europe and Japan.
