MORF-057, an oral α4β7 integrin inhibitor candidate, holds potential for treating inflammatory bowel diseases

Phase 2b EMERALD-2 clinical trial of MORF-057 expected to begin mid-year 2022

WALTHAM, Mass., March 25, 2022 (GLOBE NEWSWIRE) -- Morphic Therapeutic (Nasdaq: MORF), today announced the initiation of MORF-057-201, the EMERALD-1 study. EMERALD-1 is a phase 2a trial of MORF-057 in patients with moderate to severe ulcerative colitis. MORF-057 is a potent and selective, oral small molecule inhibitor of the α4β7 integrin being studied in patients with GI disorders, initially targeting inflammatory bowel disease (IBD).

“In the United States, over 1 million people are affected by IBD, a lifelong illness that can have a profound physical, emotional and social impact on patients,” said Praveen Tipirneni, M.D., President and Chief Executive Officer of Morphic Therapeutic. “Each of the preclinical and clinical studies of MORF-057 to date have strongly supported the potential for MORF-057 to replicate the actions of vedolizumab, an IV-infused biologic inhibitor of α4β7. MORF-057 is designed to provide an even broader group of patients with access to this proven therapeutic mechanism in pill form. With EMERALD-1 underway, we now look forward to progress in global clinical studies to advance MORF-057 as a potential new therapeutic option for people living with IBD.”

About the EMERALD-1 Study
EMERALD-1 (MORF-057-201) is an open-label multi-center phase 2a trial designed to evaluate the efficacy, safety and tolerability of MORF-057 in adults with moderate to severe ulcerative colitis. The EMERALD-1 study is planned to enroll up to 35 patients with moderate to severe ulcerative colitis who will be treated with 100 mg BID (twice daily) at sites in the United States and Europe. The primary endpoint of the trial is the change in Robarts Histopathology Index (RHI), a validated instrument that measures histological disease activity in ulcerative colitis at 12 weeks compared to baseline. Patients will then continue for an additional 40 weeks of maintenance therapy followed by a 52-week assessment. Secondary and additional outcome measures in the EMERALD-1 study include change in the modified Mayo clinic score, safety, pharmacokinetic parameters and key pharmacodynamic measures including α4β7 receptor occupancy and lymphocyte subset trafficking.

EMERALD-2 (MORF-057-202) is a global phase 2b randomized controlled trial of MORF-057 that is expected to begin mid-year 2022 and then run in parallel with EMERALD-1.

About MORF-057
Morphic is developing MORF-057 as a selective, oral small molecule inhibitor of the α4β7 integrin for patients with inflammatory bowel disease (IBD). α4β7 has been clinically validated as a target for the treatment of IBD by the success of the approved injectable antibody therapeutic vedolizumab. MORF-057, like vedolizumab, is designed to block the interactions between α4β7 on the surface of lymphocytes and the mucosal endothelial cell ligand MAdCAM-1, substantially reducing lymphocyte migration from the bloodstream into intestinal mucosal tissues and avoiding inflammation that is associated with IBD.

About Inflammatory Bowel Disease
Inflammatory Bowel Disease (IBD) comprises several autoimmune and immune-mediated conditions characterized by chronic inflammation of the gastrointestinal tract. Ulcerative colitis and Crohn’s disease are two most common types of IBD. In ulcerative colitis, inflammation is limited to the lining of the colon, whereas in Crohn’s disease inflammation can segmentally affect any part of the gastrointestinal tract through the entire thickness of the bowel wall. Symptoms of these conditions include persistent diarrhea, abdominal pain, rectal bleeding, weight loss, and fatigue. Approved medications may not adequately control symptoms for many patients, and some develop complications that require surgical removal of the colon and rectum. Among FDA approved therapies for use in moderate to severe IBD is vedolizumab, an injectable monoclonal antibody inhibitor of the integrin α4β7.
