The Life Sciences team advised Proteologix on its definitive agreement to be acquired by Johnson & Johnson for $850 million in cash, with potential for an additional milestone payment.

Proteologix’s portfolio includes PX128, a bispecific antibody targeting IL-13 plus TSLP, which is ready to enter phase 1 development for moderate to severe atopic dermatitis (AD) and moderate to severe asthma, and PX130, a bispecific antibody targeting IL-13 plus IL-22, which is in preclinical development for moderate to severe AD. In addition to PX128 and PX130, the acquisition will provide J&J with other bispecific antibody programs with applications across a variety of other diseases.

The transaction is expected to close mid-year 2024, subject to antitrust clearance and other customary closing conditions.
