Entera Bio Announces Robust Pharmacokinetic Data for First-in-Class Oral GLP-2 Peptide Tablet Treatment for Patients with Short Bowel Syndrome

- None.
The announcement by Entera Bio Ltd. regarding the positive pharmacokinetic results for an orally delivered GLP-2 agonist represents a significant advancement within the pharmaceutical industry. The ability to administer peptides orally, as opposed to subcutaneous injections, could substantially improve patient compliance and convenience. This development may also open up a new competitive space in the treatment of short bowel syndrome and similar disorders.
From a market perspective, the shift towards oral administration could disrupt the current standard of care, which relies heavily on injectable forms. If Entera's technology proves to be effective in human trials, it may capture a significant market share from injectable GLP-2 therapies. This could potentially impact the revenue streams of companies like Zealand Pharma and Ironwood, which are developing injectable therapies.
Entera's collaboration with OPKO Health, Inc. also suggests a strategic partnership that could leverage OPKO's experience in peptide therapies with Entera's novel delivery platform. The joint development could result in a faster time-to-market and a stronger commercialization strategy, potentially benefiting both companies' stock valuations.
The pharmacokinetic study conducted by Entera Bio Ltd. in rodents is a critical step in the drug development process. The success of the oral GLP-2 tablet in achieving significant systemic exposure is promising, especially considering the challenges associated with oral peptide delivery. Peptides are typically degraded in the gastrointestinal tract, making effective oral delivery a notable achievement.
The long-term implications for patients with short bowel syndrome could be profound. The condition often results in a heavy treatment burden due to the need for frequent injections. An oral tablet could greatly reduce this burden and improve the quality of life for patients. Additionally, the potential to treat other disorders involving mucosal inflammation and nutrient malabsorption with an oral tablet could expand the therapeutic applications of GLP-2 agonists.
However, it is essential to remain cautious as these are early-stage results. The transition from rodent models to human clinical trials will be the true test of the drug's efficacy and safety. Investors should monitor the progress of Entera's clinical trials closely, as positive human data could significantly affect the company's valuation and the broader market for gastrointestinal treatments.
The healthcare industry is closely observing the development of new drug delivery systems and Entera Bio's announcement could have considerable implications for the market. The current treatment landscape for short bowel syndrome is limited and a successful oral therapy could meet a significant unmet need. As Entera Bio progresses towards human clinical trials, the potential market size for their oral GLP-2 agonist could grow, especially if the therapy is applicable to a broader range of gastrointestinal disorders.
Investors should note that the market for gastrointestinal disorders is highly sensitive to innovation, particularly in delivery methods that improve patient experience. If Entera's oral tablet demonstrates comparable efficacy to injectable counterparts, it could command a premium price point. The cost-effectiveness of oral versus injectable treatments will also play a important role in adoption rates and insurance coverage, ultimately influencing the financial performance of the company.
JERUSALEM, March 20, 2024 (GLOBE NEWSWIRE) -- Entera Bio Ltd. (NASDAQ: ENTX), (“Entera” or the “Company”) a leader in the development of orally delivered peptides, announced today positive pharmacokinetic results from its collaborative research combining a proprietary long acting GLP-2 agonist developed by OPKO Health, Inc. (Nasdaq: “OPK”, or “OPKO”) with Entera’s proprietary N-Tab™ technology.
The program is focused on developing the first and only GLP-2 peptide tablet alternative for patients suffering from short bowel syndrome and additional disorders involving mucosal inflammation and nutrient malabsorption. Currently, the only approved GLP-2 agonist, which is marketed under the name Gattex® (teduglutide), requires daily sub-cutaneous injections. Zealand Pharma and Ironwood are developing long acting GLP-2 therapies requiring once and twice weekly injections.
Entera and OPKO completed a proof of concept (PoC) single dose pharmacokinetic study in rodents as the first validation for oral administration of the GLP-2 treatment. Oral tablets (1.8 mg; n=15) and IV injections (2 mg/kg; n=6) were administered to rats. Pharmacokinetic blood samples were taken for 24 hours post-dose and drug concentrations were analyzed by a validated LC-MS/MS method.
The study’s objectives were met with oral GLP-2 tablets exhibiting significant systemic exposure. Furthermore, plasma levels achieved with the oral tablet form of the GLP-2 analogue were about 10-fold higher than therapeutic plasma concentrations reported for subcutaneously administered teduglutide (Gattex® label). The pharmacokinetic analysis of the data obtained following the IV injections of the GLP-2 peptide showed the plasma half-life in rats to be about 6 times longer than the half-life reported for teduglutide in the same animal model. This data is consistent with previously reported PK data relating to OPKO’s GLP-2 peptide’s long acting profile, which had initially been developed as a weekly subcutaneous injection.
| Dose (mg) | Cmax (ng/ml) | Tmax (hr) | AUC1-24 (ng*hr/ml) |
| 1.8 | 312 | 0.5 | 678 |
“Given the challenging compliance rates attributed to injectable GLP-2 therapy, we believe a daily tablet format may address a significant unmet need in treating SBS patients more effectively. We are pleased with this first validation for the oral GLP-2 peptide program that we initiated in late 2023 in our collaboration with OPKO. The current PK data reinforces the data we previously published combining our N-Tab™ technology with teduglutide in tablet form1. Based on the promising results from the current PK study, we are planning to advance the program to assess pharmacologic effects in vivo. We look forward to updating on these data later in 2024,” said Miranda Toledano, Entera Chief Executive Officer.
About Short Bowel Syndrome
Short bowel syndrome (SBS) is a rare and potentially life-threatening malabsorptive condition caused by a significant loss of functional bowel mass (secondary to congenital defects or disease-associated loss of absorption) or physical bowel mass (secondary to extensive intestinal resection). SBS patients have a reduced ability to absorb nutrients and fluids and are at risk of malnutrition, unintended weight loss and additional symptoms due to the loss of essential vitamins and minerals2. SBS is the most common cause of chronic intestinal failure, accounting for approximately
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 on a disruptive and proprietary technology platform and its pipeline includes five differentiated, first-in-class oral peptide programs, expected to enter the into the clinic (Phase 1 to Phase 3) by 2025. The Company’s most advanced product candidate, EB613 (oral PTH (1-34), teriparatide), 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, with no prior fracture. A placebo controlled, dose ranging Phase 2 study of EB613 tablets (n= 161) met primary (PD/bone turnover biomarker) and secondary endpoints (BMD). 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 in 2024. The EB612 program is being developed as the first oral PTH(1-34) tablet peptide replacement therapy for hypoparathyroidism. Entera is also developing the first oral oxyntomodulin, a dual targeted GLP1/glucagon peptide, in tablet form for the treatment of obesity; and first oral GLP-2 peptide tablet as an injection-free alternative for patients suffering from rare malabsorption conditions such as short bowel syndrome in collaboration with OPKO Health.
