Vivani Medical Announces Successful Dosing of All Participants in SLIM-1, a Phase 1 Trial Evaluating NPM-139, a Miniature, Ultra Long-Acting Semaglutide Implant for Chronic Weight Management
Rhea-AI Summary
Vivani Medical (Nasdaq: VANI) announced full enrollment and successful initial dosing of all 20 participants in SLIM-1, a Phase 1, randomized, active-controlled trial of NPM-139, a miniature, subdermal, ultra long-acting semaglutide implant for chronic weight management.
The four-week trial in GLP-1 naïve, overweight or obese participants in Australia compares low-dose NPM-139 in 10 participants with the starting dose of Wegovy (0.25 mg/week semaglutide injection) in 10 participants, focusing on safety, tolerability, pharmacokinetics and measuring weight change. Dosing of the first 10 participants began on July 29, 2026, ahead of schedule, with the remaining 10 dosed one week later; all insertion procedures were completed without issues. Top-line data are expected in November 2026 and may support a planned Phase 2 dose-ranging trial in 2027. Vivani highlights prior NPM-139 preclinical data showing sustainable 20% weight reduction in animal models and a July 2026 collaboration with Novo Nordisk to evaluate NPM-139 and its NanoPortal implant platform, which is designed for six- to twelve-month drug delivery and rapid reversibility of GLP-1 exposure.

Dosing of the first participant commenced ahead of schedule and was rapidly followed by initial dosing in all trial participants.
SLIM-1™ trial is a Phase 1, randomized, controlled clinical trial design to characterize the safety, tolerability, and pharmacokinetics of NPM-139 including a Wegovy® (semaglutide injection) group.
Top-line data from the 20-participant trial is expected in November of 2026.
ALAMEDA, Calif., Aug. 06, 2026 (GLOBE NEWSWIRE) -- Vivani Medical, Inc. (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
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.
