Acquisition strengthens Incyte’s Inflammation and Autoimmunity (IAI) pipeline and reinforces commitment to bring innovative solutions to patients

Incyte (Nasdaq:INCY) today announced that it has completed its acquisition of Escient Pharmaceuticals, a clinical-stage drug discovery and development company advancing novel small molecule therapeutics for systemic immune and neuro-immune disorders.

"The acquisition of Escient and its first-in-class oral MRGPR antagonists bolsters our Inflammation and Autoimmunity portfolio and our commitment to creating innovative solutions that address the urgent needs of patients living with severe inflammatory diseases," stated Hervé Hoppenot, Chief Executive Officer, Incyte. "We are excited to continue the work started by the Escient team and accelerate the clinical development of these promising therapies."

Through this transaction, Incyte has added EP262 and EP547 to its portfolio. EP262 is a first-in-class, potent, highly selective, once-daily small molecule antagonist of Mas-related G protein-coupled receptor X2 (MRGPRX2). By blocking MRGPRX2 and degranulation of mast cells, EP262 has the potential to effectively treat multiple mast cell-mediated diseases including chronic inducible urticaria (CIndU), chronic spontaneous urticaria (CSU) and atopic dermatitis (AD). EP547 is a first-in-class oral MRGPRX4 antagonist with the potential to treat cholestatic pruritus and other conditions with severe pruritus.

“Over the past six years, Escient has pioneered the characterization of MRGPR biology and advanced two novel candidates, EP262 and E547, into clinical development,” commented Joshua Grass, Chief Executive Officer of Escient Pharmaceuticals. "The close of this transaction represents the recognition of value of the innovation by the Escient team, and also represents an exciting transition to Incyte, a global biopharmaceutical company that is well positioned to advance these novel candidates to address the unmet needs of patients worldwide.”

As previously disclosed, under the terms of the agreement, Incyte has acquired Escient and its assets for $750 million plus Escient’s net cash remaining at the close of the transaction, subject to customary adjustments.

Centerview Partners LLC and Goldman Sachs & Co. LLC advised Escient on the transaction, and Fenwick & West LLP acted as legal counsel for Escient. Covington & Burling LLP acted as legal counsel for Incyte.

About EP262

EP262 is a potent, highly selective once-daily small molecule antagonist of MRGPRX2, a receptor expressed on mast cells that is activated by numerous ligands, including many peptides released from sensory neurons as well as other cell types. In response to MRGPRX2 activation, mast cells release histamine, tryptase, chymase, chemokines and cytokines, which can cause itchy hives, angioedema, type 2 inflammation (through engagement of the adaptive immune system) and chronic pruritus and pain. Preclinical data demonstrate that, by blocking activation of MRGPRX2, EP262 has the potential to effectively treat a broad range of mast cell-mediated conditions, with an initial focus on chronic urticarias and atopic dermatitis.

About EP547

EP547 is a potent, highly selective antagonist that blocks the activation of MRGPRX4 by various bile acids, bilirubin and urobilin. By virtue of this disease-specific mechanism of action, EP547 has the potential to be a highly targeted and efficacious treatment for cholestatic and uremic pruritus.
