Escient Pharmaceuticals Announces Oral Presentation of Data Highlighting the Preclinical Pharmacology of EP262 at the American Academy of Allergy, Asthma and Immunology Annual Meeting
- Data supported selection of EP262 as a potent, highly selective development candidate
- Clinical development of EP262 recently initiated as a novel treatment for a broad range of mast cell mediated diseases including chronic spontaneous and inducible urticarias
SAN DIEGO, Calif., February 26, 2023 — Escient Pharmaceuticals, a clinical-stage company advancing novel small molecule therapeutics for the potential treatment of a broad range of neurosensory-inflammatory disorders, today announced the presentation of preclinical data related to the company’s EP262 development program at the American Academy of Allergy, Asthma and Immunology Annual meeting being held in San Antonio, TX, February 24-27, 2023.
EP262 is a potent, highly selective antagonist of MRGPRX2 which inhibits agonist-induced mast cell degranulation and represents a novel potential treatment for a broad range of mast cell-mediated disorders. The presentation highlights preclinical data demonstrating that EP262 potently inhibits MRGPRX2-mediated degranulation of human mast cells and inhibits mast cell degranulation-induced vascular permeability in proprietary humanized MRGPRX2 transgenic mice.
Details of the presentation are shown below:

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. Escient’s preclinical data demonstrates that, by blocking activation of MRGPRX2, EP262 has the potential to effectively treat a broad range of mast-cell-mediated diseases, with an initial focus on chronic urticarias and atopic dermatitis.
About Chronic Urticaria
Chronic urticaria, defined as urticaria persisting for more than 6 weeks, manifests with very itchy hives that may vary in size and can significantly impact a patient’s quality of life by interfering with sleep and daily activities. Some patients with chronic urticaria may also develop swelling deeper under the skin or in other tissues (angioedema). There are two main forms of chronic urticaria. In chronic spontaneous urticaria (CSU), hives occur spontaneously, without known triggers. In chronic inducible urticaria (CIndU), hives are induced by specific triggers such as cold exposure (cold urticaria) or touch (symptomatic dermographism), among others.
