JERUSALEM and MIAMI, Sept. 25, 2024 (GLOBE NEWSWIRE) -- Entera Bio Ltd. (NASDAQ: ENTX) (Entera), a leader in the development of orally delivered peptides, and OPKO Health, Inc. (NASDAQ: OPK) (OPKO) announced today topline pharmacokinetic/pharmacodynamic (PK/PD) results from their ongoing collaborative research combining a proprietary long-acting oxyntomodulin (OXM) analog developed by OPKO and Entera’s proprietary N-Tab™ technology. The program is focused on developing the first oral dual agonist GLP-1/glucagon peptide as a potential once-daily treatment for patients with obesity, metabolic and fibrotic disorders. OXM is a naturally occurring peptide hormone found in the small intestine that acts to suppress appetite and induce weight loss. Entera and OPKO have completed in vivo proof-of-concept PK/PD studies in rodent and pig models. The studies’ objectives were met with oral OXM exhibiting significant systemic exposure following a single dose in both models. Furthermore, a favorable PK profile and bioavailability were shown with oral OXM. In the pig model, oral OXM achieved high plasma concentrations with prolonged systemic exposure, which is consistent with the reported half-life for semaglutide (Rybelsus®), the only approved oral GLP-1 analog. To assess the pharmacologic effect of oral OXM, a glucose tolerance test was performed in rats. Oral OXM showed a statistically significant reduction in plasma glucose levels post-glucose administration compared with placebo. Entera and OPKO plan to present these data at an upcoming clinical conference. “We are very pleased with the progress we are making in our collaboration with OPKO. These bioavailability and pharmacological data support continuing toward IND-enabling efforts for the program,” said Miranda Toledano, Entera Chief Executive Officer. OPKO previously reported that weekly injections of pegylated OXM demonstrated significant weight loss and reduction in HbA1, triglyceride and cholesterol levels in 113 obese and diabetic patients in a Phase 2B study. The OXM agonist peptide has since been modified to maintain its long-acting profile while increasing its potential potency. Currently, there are no approved OXM agonists available, and those in development by others are small molecules or require subcutaneous injections. About Entera Bio Entera is a clinical-stage company focused on developing oral peptide or protein replacement therapies for significant unmet medical needs where an oral tablet form holds the potential to transform the standard of care. The Company leverages a disruptive and proprietary technology platform (N-Tab™) and its pipeline includes five differentiated, first-in-class oral peptide programs, expected to enter the clinic (Phase 1 to Phase 3) by 2025. The Company’s most advanced product candidate, EB613 (oral PTH (1-34)), is being developed as the first oral, osteoanabolic (bone building) once-daily tablet treatment for post-menopausal women with low BMD and high-risk osteoporosis. A placebo controlled, dose ranging Phase 2 study of EB613 tablets (n=161) met primary (PD/bone turnover biomarker) and secondary (BMD) endpoints. Entera is preparing to initiate a Phase 3 registrational study for EB613 pursuant to the FDA’s qualification of a quantitative BMD endpoint, which is expected to occur by January 2025. The EB612 program is being developed as the first oral PTH (1-34) tablet peptide replacement therapy for hypoparathyroidism. In collaboration with OPKO Health, Entera is also developing the first oral oxyntomodulin, a dual targeted GLP-1/glucagon peptide, in tablet form for the treatment of obesity; and the first oral GLP-2 peptide tablet as an injection-free alternative for patients suffering from rare malabsorption conditions such as short bowel syndrome.
