Ensho Therapeutics Launches with Phase 2-Ready Oral α4β7 Inhibitor for Inflammatory Bowel Disease

Portfolio of Oral Selective α4β7 Inhibitors Acquired from EA Pharma, Eisai’s GI Subsidiary Phase 2 Clinical Program in Ulcerative Colitis to Start in First Half of 2025 with Lead Asset Seasoned Executive Team with History of Execution in Inflammatory Bowel Disease Drug Development toJoin Ensho on July 1 Founded by Neena Bitritto-Garg, Veteran Biotech Equity Research Analyst and Former Eisai Staffer MORRIS PLAINS, N.J., June 27, 2024 (GLOBE NEWSWIRE) — Ensho Therapeutics, Inc., a privately held, clinical-stage biopharmaceutical company focused on developing breakthrough oral therapies for patients with inflammatory diseases, launched today with the announcement that it has acquired a portfolio of oral α4β7 integrin inhibitors through a worldwide exclusive license agreement with EA Pharma Co., Ltd., a subsidiary of Eisai Co., Ltd. Under the terms of the agreement, Ensho has the right to develop, manufacture, and commercialize these assets globally, excluding certain Asian jurisdictions. The two companies jointly announced the exclusive license agreement in a separate press release today. Based on results of an extensive Phase 1 clinical program, Ensho has selected NSHO-101, (also known as EA1080), as its lead drug candidate from the portfolio. The Phase 1 program evaluated single and multiple ascending doses of NSHO-101 in over 180 healthy subjects. Results demonstrated favorable pharmacokinetics (PK) and pharmacodynamics (PD), including target engagement. NSHO-101 was generally safe and well-tolerated in healthy subjects. Results of the Phase 1 program support Ensho’s plans to initiate Phase 2 clinical development in the first half of 2025, starting with ulcerative colitis (UC). Neena Bitritto-Garg, CFA, founder, president and chief executive officer of Ensho, stated, “We are thrilled to acquire this portfolio of oral selective α4β7 integrin inhibitors derived from AJM300, an oral α4 inhibitor that has been approved in Japan for induction therapy in UC. This, along with my history with Eisai and EA Pharma’s impeccable standards for continuous improvement in drug development, led me to found Ensho around this portfolio. We believe NSHO-101 could be a transformational alternative therapy for patients who continue to suffer from IBD despite multiple lines of therapy.” Ensho has recruited a world-class team of executives with decades of experience in inflammatory and gastrointestinal (GI) disease drug development. The team will join Ms. Bitritto-Garg to develop and potentially commercialize these important oral agents for the inflammatory bowel disease (IBD) market. Ms. Bitritto-Garg continued, “I am very pleased to welcome to Ensho our seasoned team of executives, including Bittoo Kanwar, M.D., former chief medical officer of Telavant, which was acquired by Roche last year. The team’s decades of experience in IBD drug development will enable us to not only move quickly, but also smartly, into Phase 2 clinical development with NSHO-101.” Bittoo Kanwar, M.D., stated, “Joining Neena to advance Ensho and its portfolio of promising IBD assets was a tremendously attractive opportunity, given the significant unmet medical needs in IBD, the high potential and validated mechanism of α4β7, and the potential of our novel, oral clinical development candidates to offer differentiated attributes to patients and physicians looking for therapeutic alternatives. In collaboration with our newly formed Ensho team, many of whom have a long history of working together, we look forward to expeditiously advancing our lead asset, NSHO-101, into Phase 2 development early next year.” Ensho Therapeutics was borne out of Ms. Bitritto-Garg’s experience working at Eisai, the parent company of EA Pharma, on business development and in management of the company’s key alliance with Biogen Inc. on Leqembi (lecanemab), which is currently being launched in multiple countries for the treatment of early Alzheimer’s disease. She brings to Ensho nearly a decade’s worth of experience as an equity research analyst covering the biotechnology sector, including the neuroscience and immunology therapeutic areas. Immediately prior to founding Ensho, she led biotech and biopharma equity research strategy at multiple global banks, including at Citigroup Inc., where she was the head of U.S. biotechnology equity research. Ms. Bitritto-Garg is a graduate of the Roy and Diana Vagelos Program in Life Sciences and Management (LSM) at the University of Pennsylvania and holds dual degrees in Biochemistry (B.A.) from the College of Arts and Sciences and Economics (B.S.) with a concentration in finance from Wharton.

About Selective a4b7 Integrin Inhibitionα4β7 is a cell surface receptor that helps regulate the migration of immune cells to the intestine and plays a key role in controlling inflammatory responses. It binds to mucosal addressin cell adhesion molecule-1 (MAdCAM-1), which is expressed on intestinal venules and is upregulated in response to inflammation. This interaction helps facilitate the transport of leukocytes and recruitment of effector lymphocytes to the gut mucosa in IBD. Because α4β7 is found primarily in the gut, this localized action provides immune cell inhibition where it is most relevant, potentially minimizing side effects and preserving overall immune cell function. Decades of research validate α4β7 inhibition as an anti-inflammatory mechanism in IBD, which has been further substantiated by the approval of a commercially available antibody, vedolizumab. Yet, there are no approved orally administered α4β7 inhibitors agents for the treatment of IBD. About NSHO-101 (also known as EA1080)NSHO-101 is a novel, oral, selective α4β7 integrin inhibitor designed for the potential treatment of patients with IBD. The Phase 1 clinical program for NSHO-101 evaluated 184 healthy subjects to assess safety, tolerability, food effects, PK and PD of single and multiple ascending doses of NSHO-101. NSHO-101 demonstrated target engagement in this Phase 1 program. There were no appreciable increases in peripheral lymphocytes, suggesting its activity is gut-restricted. NSHO-101 was generally safe and well tolerated. Ensho plans to initiate Phase 2 clinical development of NSHO-101 as a potential treatment for UC in the first half of 2025. About Ensho Therapeutics, Inc.Ensho Therapeutics, Inc. is a privately held, clinical-stage biopharmaceutical company focused on developing breakthrough oral therapies for patients with inflammatory diseases. The company’s initial focus is on a pipeline of oral, selective small molecule inhibitors of lymphocyte homing integrin α4β7 for IBD, a mechanism already validated by a commercially available antibody. Ensho’s assets were acquired from EA Pharma Co., Ltd., a subsidiary of Eisai Co., Ltd., that is focused on gastrointestinal disease. Ensho is preparing to initiate a Phase 2 clinical program in UC with NSHO-101, the lead asset in the company’s pipeline.
