ALAMEDA, Calif., Aug. 06, 2026 (GLOBE NEWSWIRE) -- <a href="https://www.globenewswire.com/Tracker?data=Y388AVYx5p80DtlLkCe8dX5CTJrtjMFbF8k_fsNFnzI4GpgNG1CQTcLFMYLtvodlnAfNyXT0Fvu4_grs4Qt3NuBvJtilcXl_bqQXssg3lf8=" rel="nofollow" target="_blank" title="">Vivani Medical, Inc.</a> (Nasdaq: VANI) today announced full enrollment and successful initial dosing of all participants in its SLIM-1™ Phase 1 trial for NPM-139, a miniature, subdermal semaglutide implant being designed to provide six- to twelve-months of continuous drug delivery utilizing our proprietary NanoPortal™ technology. The trial of 20 GLP-1 naïve participants in Australia includes low-doses of NPM-139 and Wegovy® to assess safety, tolerability, and pharmacokinetics. Changes in weight will be measured. “Dosing of the first 10 participants occurred on July 29, ahead of schedule. The remaining 10 participants were dosed one week later. All insertion procedures were completed successfully without any issues. Expeditious full enrollment of SLIM-1 trial participants highlights our commitment to rapidly advance the development of our innovative GLP-1 product candidates in chronic weight management and type 2 diabetes,” said Adam Mendelsohn, Ph.D., CEO of Vivani Medical. “We look forward to sharing top-line SLIM-1 clinical data later this year which we anticipate will pave the way for initiation of a Phase 2 dose-ranging trial in 2027.” This milestone follows NPM-139 preclinical studies demonstrating sustainable 20% weight reduction in animal models and a <a href="https://www.globenewswire.com/Tracker?data=LnUDXKQXG9UqZVStimL850a5DbTGq2X3H_8yQvKyS90txJ2qAJWL3MwJaITViLXCVKaj8cX96s8FH9CS-vpzBunpAV8U_b70F3Q_9c8YAuDz6GiiqtJoDVmPnDp1dAupvNLHFh1fmzIINATyX74w2kIVELFwsFSKEcg8lU9-a1D7zikfn6QvPsdsbUqKnPB7mEHkvju0TBRJF9GtcVELyJIovfX1jN_hp8Nte7fOYFxLBiYr1Hn4AesESSihYQuSK3icAYyTK-hcxh3kO1g_1g==" rel="nofollow" target="_blank" title="">July 2026 agreement with Novo Nordisk</a> to evaluate NPM-139 and Vivani’s proprietary NanoPortal implant technology. In addition to NPM-139’s primary aim to improve convenience, medication adherence and tolerability, NanoPortal implants are uniquely designed to enable infrequent administration (six months or longer) and the ability to rapidly reverse GLP-1 drug exposure when cessation of therapy is needed or desired. Reversibility can be an important clinical consideration in certain situations, including when a woman becomes pregnant or when patients undergoing surgery have an increased aspiration risk. About SLIM-1 SLIM-1 is an open-label, active-controlled trial evaluating a low-dose NPM-139 (semaglutide implant) given to 10 participants, and the starting dose of Wegovy (0.25mg/week semaglutide injection) also given to 10 participants, over a four-week duration. The trial is designed to evaluate the safety, tolerability and pharmacokinetic profile in overweight or obese participants who are otherwise healthy. Top-line results from SLIM-1 are expected to be available in November. About Vivani Medical, Inc. Leveraging its proprietary NanoPortal™ platform, Vivani develops miniature, biopharmaceutical implants designed to deliver drug molecules steadily over extended periods of time with the goal of guaranteeing adherence and improving patient tolerance to their medication. Vivani is developing a portfolio of GLP-1 based implants for metabolic diseases including obesity and type 2 diabetes. These NanoPortal implants are designed for once- or twice-yearly administration to provide patients with the opportunity to realize the full potential benefit of their medication by avoiding the numerous challenges associated with the daily or weekly administration of orals and injectables, including tolerability issues and loss of efficacy. 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.
