While the value of partnerships and collaborations have climbed mostly upward in recent years, the most impressive increase has been seen with deals that are worth $1 billion or more – led in 2023 with a $22 billion antibody-drug conjugate pact between Daiichi Sankyo Co. Ltd. and Merck & Co. Inc.
Major contract research development and manufacturing organizations (CDMO) out of Asia are announcing plans to ramp up production and antibody-drug conjugate (ADC) capabilities worldwide.
The zeal for antibody-drug conjugates (ADCs), a prominent focus for dealmaking in 2023, shows no signs of waning, as Johnson & Johnson greeted attendees of the J.P. Morgan Healthcare Conference (JPM) with news of its $2 billion buyout of Ambrx Biopharma Inc., picking up rights to an ADC platform along with a promising candidate targeting advanced prostate cancer. Under the terms, J&J agreed to acquire all outstanding shares of San Diego-based Ambrx for $28 apiece, marketing a 105% premium to the firm’s Jan. 5 closing price. Unsurprisingly, Ambrx’s stock (NASDAQ:AMAM) gained 101.5% to close Jan. 8 at $27.47.

Pharma-biotech pairings continued apace in the antibody-drug conjugate (ADC) space, with 2023 capped by Legochem Biosciences Inc. signing a $1.7 billion licensure deal with Johnson & Johnson arm Janssen Biotech Inc. for the former’s Trop2-directed compound, the second-biggest Korean technology transfer agreement.

South Korean biotech Pinotbio Co. Ltd. inked a $250 million (₩320 billion) licensing deal with Princeton, N.J.-based Conjugatebio Inc. to develop 10 antibody-drug conjugate (ADC) targets with Pinotbio’s ADC platform technology. The deal announced on Dec. 21 adds to a previous agreement between the two companies last year. Pinotbio and Conjugate first teamed up to discover and develop five ADC targets in June 2022.
The spate of recent deals involving antibody-drug conjugates (ADC) continues in a field composed of record-breaking agreements in 2023. The newest of the deals were focused on Asia.
