A Mixed-Methods Exploratory Pilot Study of the Investigational MYNERVA Leia Sensory Prosthesis in U.S. Adults With Peripheral Neuropathy (MYN-L001-002)

21. september 2026 opdateret af: Mynerva Inc.

This is a US-specific pilot study to evaluate the short- and long-term effects of the investigational MYNERVA Leia Sensory Prosthesis on gait, neuropathic symptoms and quality of life in US adults with peripheral neuropathy, and to capture insights on the device's usability and perceived clinical effects.

Detaljeret beskrivelse

Through a single, two-hour in-person session per participant, this study is intended to generate preliminary evidence on whether the Leia Sensory Prosthesis improves gait patterns and sensory function in US adults with peripheral neuropathy, based on short-term device use.

A phone follow-up will inform on participant-reported clinical effects of the single use of Leia, and their duration.

Findings will also allow to gain a more comprehensive understanding of US demographic specifics to inform future device design, usability improvements, and potential adoption barriers ahead of further clinical development.

Beskrivelse

Inclusion Criteria:

  • Signed informed consent prior to any study procedure
  • Adults ≥ 18 years
  • Clinical diagnosis of peripheral neuropathy, confirmed per site procedures
  • Gait or balance difficulties as self-reported and confirmed by single-leg stance < 30 seconds
  • Able to walk without walking aids
  • Stable supplements and medications ≥ 1 month before intervention and willing to maintain stability during 1 month following the intervention
  • Willingness and ability to attend the initial in-person session (up to 2 hours) and follow-up calls.

Exclusion Criteria:

  • Untreated/unhealed lesions of any kind (e.g., wounds, swelling, infection, inflamed area of skin or eruptions on the lower leg (foot and ankle) or near device use (e.g., untreated lymphedema, phlebitis, thrombo-phlebitis or varicose veins)
  • Untreated/unhealed fractures in the foot and ankle
  • Cancerous growth in the planned treatment area
  • Severe peripheral vascular disease (e.g., gangrene)
  • Implanted electrical devices or pacemakers
  • Lower-limb orthoses/braces that cannot be removed for assessments
  • Pregnant or breast-feeding females
  • Usage of other medical devices for the relief of neuropathic symptoms during the study
  • Current participation in any other clinical study using an investigational device or investigational drug
  • Orthopedic conditions substantially limiting gait (e.g., failed back surgery syndrome (FBSS), recent hip or knee replacement, unstable fractures) as judged by the investigator
  • Inability to perceive the stimulation (tested by MYNERVA staff during calibration)
  • Cognitive impairment or poor command of English that preclude informed consent or answering questionnaires

Foranstaltningsbeskrivelse
Tidsramme
Single-leg stance
Tidsramme: At visit 1 (Day 1) before the intervention and at visit 1 (Day 1) during the single 30 minutes treatment session

The single-leg stance test is a simple clinical assessment used to evaluate static balance and postural control. The patient is instructed to stand unassisted on one leg for up to 30 seconds, with eyes open and arms by the side. The test is performed in both legs. Inability to maintain the position for 30 seconds indicating impaired balance and increased risk of falls.

At visit 1 (Day 1) before the intervention and at visit 1 (Day 1) during the single 30 minutes treatment session
Timed-up and Go (TUG) in seconds
Tidsramme: At visit 1 (Day 1) before the intervention and at visit 1 (Day 1) during the single 30 minutes treatment session

The Timed Up and Go (TUG) test assesses functional mobility. Participants are instructed to stand up from a chair, walk 3 metres at their usual pace, turn around, walk back to the chair, and sit down. The time from the command to start until the participant is seated again is recorded in seconds. A shorter time indicates better functional mobility.
