Vivani Medical Announces Positive Preclinical Weight Loss Data for NPM-139 Semaglutide Implant, with Potential for Once-Yearly Dosing

Rhea-AI Summary

Vivani Medical (NASDAQ: VANI) has announced promising preclinical data for NPM-139, its subdermal semaglutide implant for chronic weight management. The implant, utilizing their proprietary NanoPortal™ technology, demonstrated nearly 20% placebo-adjusted weight loss from a single administration in healthy rats over a 91-day treatment period.

The technology successfully delivers semaglutide (active ingredient in Ozempic®/Wegovy®) with potential for once or twice-yearly dosing. NPM-139 has shown therapeutic semaglutide exposure levels over six months in healthy rats, with in vitro stability measurements indicating potential for once-yearly administration.

The company's ongoing LIBERATE-1 clinical study for NPM-115 (exenatide implant) is progressing, with top-line data expected by mid-2025. This study will provide critical information for both NPM-115 and NPM-139 development, representing the first human application of NanoPortal technology.

NPM-139 is a miniature, subdermal implant in development for chronic weight management designed to guarantee medication adherence and potentially improve treatment tolerability by providing smooth and steady delivery of GLP-1 therapy

ALAMEDA, Calif., March 26, 2025 (GLOBE NEWSWIRE) -- Vivani Medical, Inc. (NASDAQ: VANI) (“Vivani” or the “Company”), a clinical-stage biopharmaceutical company developing miniature, ultra long-acting drug implants, today announced promising preclinical data for NPM-139, its subdermal semaglutide implant under development for chronic weight management in obese and overweight individuals. These results reinforce the company’s commitment to addressing chronic weight management and other chronic diseases by leveraging its proprietary NanoPortal™ implant technology which is designed to enable smooth and steady delivery of therapeutic molecules including GLP-1 therapy. This development marks a significant advancement in improving medication adherence and patient convenience, addressing a critical gap in the treatment of chronic diseases including obesity and type 2 diabetes.

“Products containing semaglutide generated $25 billion in 2024 and demand for these products continues to soar. Since over half of these patients regularly miss doses as indicated by real-world medication adherence data, we believe that there is a tremendous opportunity for a more convenient delivery option that will eliminate missed doses and thereby improve real-world health outcomes. We continue to believe that the primary expected advantages of our proprietary NanoPortal implant technology, improving medication adherence and medication tolerability, have the potential to transform and expand the adoption of GLP-1 therapy in the future,” said Adam Mendelsohn, Ph.D., Vivani Medical’s Chief Executive Officer. “This preclinical demonstration of NPM-139 comes on the heels of having rapidly enrolled and successfully implanted an initial group of subjects in LIBERATE-1, our first-in-human study with NPM-115, which we expect will pave the road for NPM-139 as development continues for both programs.”

In an ongoing study in healthy rats, a single administration of the semaglutide implant NPM-139 resulted in body weights that were nearly 20% lower than a sham implant control group throughout a 91-day treatment period. Like NPM-119 and NPM-115, NPM-139 has demonstrated smooth, non-fluctuating in vivo release; this was confirmed by pharmacokinetic data from this study which demonstrated continuous and steady semaglutide exposure throughout the study period. NPM-139 has previously demonstrated therapeutic semaglutide exposure levels in pharmacokinetic data over a six-month duration in healthy rats. In vitro chemical and physical stability measurements for durations exceeding one year indicate the potential for once-yearly administration of NPM-139. Together, these data demonstrate the versatility of the NanoPortal technology beyond NPM-115 (exenatide implant) and provide significant encouragement for continued development of each program.

The ongoing NPM-115 clinical study, LIBERATE-1, for which the first successful implantation was recently announced, remains on track to produce top-line data by mid-2025. While LIBERATE-1 will primarily inform continued development of NPM-115, LIBERATE-1 will also provide critical information to support the development of NPM-139 and other pipeline programs since it represents the first human application of the NanoPortal technology.

About LIBERATE-1

LIBERATE-1 is a Phase 1, first-in-human study of a miniature, ultra long-acting GLP-1 (exenatide) implant, NPM-115, to investigate the safety, tolerability, and full pharmacokinetic profile in obese or overweight subjects. The trial has enrolled participants who are intended to be titrated on weekly semaglutide injections for 8 weeks (0.25 mg/week for 4 weeks followed by 0.5 mg/week for 4 weeks) before being randomized to receive a single administration of Vivani’s exenatide implant (NPM-115, n=8), weekly exenatide injections (Bydureon BCise®, n=8), or weekly 1 mg semaglutide injections (Wegovy®, n=8) for a 9-week treatment duration. Changes in weight will be measured. The study is currently on-going at two study centers in Australia and is fully enrolled. Top-line data from the study is anticipated to be available in mid-2025.

Vivani has successfully utilized research and development rebates from the Australian government for relevant 2024 expenses to defray a portion of the costs from this clinical trial and anticipates being able to utilize similar rebates going forward. Since clinical studies conducted in Australia comply with the International Conference on Harmonization guidelines, data generated in Australia generally are acceptable to the U.S. Food and Drug Administration and other regulatory authorities. Vivani anticipates use of relevant clinical data generated in Australia to support regulatory submissions in other geographies including the United States. Additional guidance regarding future regulatory submissions will be provided as new information becomes available.

About Vivani Medical, Inc.

Leveraging its proprietary NanoPortal™ platform, Vivani develops biopharmaceutical implants designed to deliver drug molecules steadily over extended periods of time with the goal of guaranteeing adherence, and potentially to improve patient tolerance to their medication. Vivani’s lead program, NPM-115, is a six-month, subdermal, GLP-1 (exenatide) implant under development for chronic weight management in obese or overweight individuals. Vivani’s emerging pipeline includes NPM-139 (semaglutide implant) which is also under development for chronic weight management. The semaglutide implant is being initially developed as a twice-yearly implant but it has the added potential benefit of once-yearly administration. NPM-119 refers to the Company’s six-month, subdermal, GLP-1 (exenatide) implant under development for the treatment of type 2 diabetes. These NanoPortal implants are designed to provide patients with the opportunity to realize the full potential benefit of their medication by avoiding the challenges associated with the daily or weekly administration of orals and injectables. Medication non-adherence occurs when patients do not take their medication as prescribed. This affects an alarming number of patients, approximately 50%, including those taking daily pills. Medication non-adherence, which contributes to more than $500 billion in annual avoidable healthcare costs and 125,000 potentially preventable deaths annually in the U.S. alone, is a primary and daunting reason why obese or overweight patients, and patients taking type 2 diabetes or other chronic disease treatments, face significant challenges in achieving positive real-world effectiveness. While the current GLP-1 landscape includes over 50 new molecular entities under clinical stage development, Vivani remains confident that its highly differentiated portfolio of miniature long-acting GLP-1 implants have the potential to provide an attractive therapeutic option for patients, prescribers and payers.
