Vivani Medical Announces Positive Preclinical Liver Fat Results with Miniature, Ultra Long-Acting GLP-1 Implant

Vivani's GLP-1 (exenatide) implant produced sham-implant adjusted liver fat reduction of 82% in an obese mouse model from a single administration with expected twice-yearly dosing

Vivani previously announced sham-implant adjusted preclinical weight loss of 20%, which is comparable to the weight loss produced from the semaglutide (active ingredient in Ozempic^®/Wegovy^®) injection control arm in the same study

Clinical development of Vivani's exenatide implant in overweight and obese patients as part of the Company's NPM-115 program remains on track to commence in the fourth quarter of 2024

Vivani Medical, Inc. (NASDAQ:VANI) ("Vivani" or the "Company"), an innovative biopharmaceutical company developing miniature, ultra long-acting, subdermal drug implants, today reported positive preclinical liver fat results with its exenatide implant.

"The reduction in liver fat observed preclinically with our miniature, subdermal exenatide implant, provides further support that the NanoPortal™ implant technology continues to hold great potential as a highly differentiated treatment option for the treatment of obesity and chronic weight management as well as related metabolic disorders," said Adam Mendelsohn, Ph.D., Vivani President and Chief Executive Officer. "While the currently marketed GLP-1 based drugs have made profound improvements in the treatment of chronic diseases, including obesity and chronic weight management, significant barriers to optimal patient outcomes persist due to medication non-adherence and poor tolerability. We remain committed to the development of our portfolio of innovative, miniature, GLP-1 implant candidates and their potential to improve real-world patient outcomes by improving medication adherence. In addition, we believe that our implant's minimally fluctuating release profile combined with avoiding inevitable drug fluctuations that result from poor adherence may have the potential to improve treatment tolerability, a primary complaint associated with currently available GLP-1 treatment options. Our first clinical study, LIBERATE-1™, is anticipated to start in the fourth quarter of 2024 with results in 2025."

Liver Fat Reduction in High Fat Diet-induced Obese Mice

These liver fat data are consistent with published results from similar investigations with semaglutide, the active pharmaceutical ingredient in Ozempic and Wegovy.

Previously reported results from this study in high-fat diet-induced obese mice demonstrated that Vivani's exenatide implant generated weight loss of approximately 20% compared to a sham implant control after a 28-day treatment duration, comparable to the weight loss observed in the semaglutide active control arm in the study. The supratherapeutic doses provided for the exenatide implant (single administration delivering exenatide at ~530 nmol/kg/day) and semaglutide (weekly injections of ~2,700 nmol/kg/week) were selected to maximize the weight-loss potential of both exenatide and semaglutide.

NPM-115 Program

In July 2024, Vivani provided an update on the clinical development plans for its obesity program, NPM-115, which will evaluate the Company's miniature, long-acting exenatide implant in obese and overweight patients. In support of the recent strategic shift to prioritize the development of its obesity and chronic weight management portfolio, the Company announced revised plans to evaluate its GLP-1 implant as part of the NPM-115 program in individuals who are obese or overweight in the Company's first-in-human study, LIBERATE-1. This study will enroll participants who will be titrated on weekly semaglutide (Wegovy) for eight weeks before being randomized to receive a single exenatide implant, weekly exenatide injections (Bydureon BCise^®), or weekly semaglutide injections for a nine-week treatment duration. The Company expects the study to be initiated in the fourth quarter of 2024 in Australia, pending regulatory approval, with data from the study anticipated in 2025.

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 tolerance to their medication. Vivani's lead program, NPM-115, will evaluate a miniature, six-month, subdermal, GLP-1 (exenatide) implant for chronic weight management in obese or overweight individuals. Vivani's emerging pipeline also includes NPM-139 (semaglutide implant) which is also under development for chronic weight management in obese and overweight patients. NPM-139 has the added potential benefit of once-yearly administration. NPM-119 refers to the Company's clinical program which will evaluate its six-month, subdermal exenatide implant for the treatment of type 2 diabetes. These NanoPortal implants are designed to provide individuals 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 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 individuals, and those taking treatments for type 2 diabetes or other chronic diseases, 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.
