Johnson & Johnson to acquire Proteologix Inc and with it PX 128 and PX 130
Johnson & Johnson announced that it has entered into a definitive agreement to acquire Proteologix, Inc., a privately-held biotechnology company focused on bispecific antibodies for immune-mediated diseases, for $850 million in cash, with potential for an additional milestone payment.
Proteologix’s portfolio includes PX 128, 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 PX 130, a bispecific antibody targeting IL-13 plus IL-22, which is in preclinical development for moderate to severe AD. Since AD and asthma are both heterogeneous diseases with different disease-driving pathways in distinct patient subpopulations, targeting multiple pathways offers the potential to deliver high-bar efficacy and remission.
