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.

It’s a little early for St. Patrick’s Day, but the green is surely flowing for Acutus Medical Inc. as the company achieved its second milestone under the terms of its asset purchase agreement with Medtronic plc and triggered a $17 million payment.

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.

It was a grueling year for life sciences companies trying to raise money and keep afloat. Despite the industry’s front-line position in fighting COVID-19, sparking an overzealous enthusiasm, the soaring financings and rising stock prices of 2020 took an about-face beginning in 2021 and dropping even further in 2022. Share prices plummeted amid economic turmoil that included rising inflation, geopolitical pressures, and budgetary threats. Investors closed their wallets just as burn rates increased and funds diminished. Partnering fell to pre-pandemic levels and mergers and acquisitions hit a five-year low. Without capital, the uncertainty led companies to the only other option, workforce reductions and restructurings, pushing aside promising candidates at the expense of patients.

Fujifilm Corp. inked an agreement to purchase the global digital pathology business of Inspirata Inc., paving the way for expansion of its Synapse enterprise imaging offering. The transaction includes Inspirata’s Dynamyx software, which Fujifilm has distributed in the U.K. and certain European Union countries since mid-2020. Under the agreement, Fujifilm will acquire Inspirata’s digital pathology technology, as well as employees and customers associated with the brand. Financial terms of the deal were not disclosed. It is expected to close in early 2023.
