Incyte Corp. has entered into a definitive agreement to acquire Escient Pharmaceuticals, a clinical-stage drug discovery and development company advancing small molecules for systemic immune and neuro-immune disorders, for $750 million plus Escient’s net cash remaining at the close of the transaction.
 
The acquisition includes EP262, a first-in-class, potent, highly selective, once-daily small molecule antagonist of Mas-related G protein-coupled receptor X2 (MRGPRX2) and EP547, a first-in-class oral MRGPRX4 antagonist.
 
By blocking MRGPRX2 and degranulation of mast cells, EP262 has the potential to effectively treat multiple mast cell-mediated diseases including atopic dermatitis (AD), chronic inducible urticaria (CIndU) and chronic spontaneous urticaria (CSU). Preclinical studies have shown that EP262 improved AD-like skin lesions and markers of type 2 inflammation. Additionally, in a Phase 1 study of 64 healthy volunteers, EP262 was safe and well tolerated at all doses tested, with no serious or severe adverse events.
 
“As a company dedicated to innovation and the discovery of transformative medicines, we are excited to add EP262 and EP547 to our portfolio. This acquisition builds on our strategy to develop differentiated and first-in-class medicines with high potential,” said Hervé Hoppenot, Chief Executive Officer, Incyte. “EP262 and EP547 are complementary additions to our portfolio, providing an opportunity to leverage our expertise, address the needs of patients with inflammatory diseases and additional potential launch opportunities starting in 2029.”
 
“These drug candidates are the result of the highly innovative research performed by Escient’s employees and scientific collaborators,” said Joshua A. Grass, President and Chief Executive Officer, Escient. “With its experienced development and commercial teams in Inflammation and Autoimmunity and portfolio of commercial and development stage products, Incyte is well positioned to translate this new science into valuable medicines for patients.”
 
The acquisition, subject to customary conditions, is expected to close by the third quarter of 2024.
