A Study to Evaluate the BrainPort Vision Device in Individuals Blinded by Traumatic Injury
A study testing BrainPort V200 Device in people with Blindness, run by Wicab at 3 sites in United States.
Trial summary
The BrainPort V200 Device is a wearable, non-surgical, prosthetic device intended for people who are profoundly blind. The BrainPort V200 translates images captured by a digital camera into electro-tactile stimulation presented on the user's tongue to perceive shape, size, location, and motion of objects within the… Read more about this study

About this study
Official title: Safety and Efficacy of the BrainPort V200 Device in Individuals Blinded by Traumatic Injury
The BrainPort V200 Device is a wearable, non-surgical, prosthetic device intended for people who are profoundly blind. The BrainPort V200 translates images captured by a digital camera into electro-tactile stimulation presented on the user's tongue to perceive shape, size, location, and motion of objects within the environment. The purpose of this study is to evaluate the safety and functional performance of the BrainPort V200 device in individuals who have been medically documented as blind, light perception or worse, due to a traumatic injury (cortical or ocular).

What is being measured
The primary outcome is the main question the study is designed to answer.
To assess the safety of electrical stimulation on the tongue (to demonstrate no occurrence of a clinically significant device-related adverse event)
The primary safety objective is to demonstrate no occurrence of a clinically significant device-related adverse event.
Measured: 12 months
To assess the efficacy of the BrainPort device as measured by an object recognition task (to demonstrate at least 35% of subjects achieve a success rate in object recognition exceeding that expected by chance alone)
The primary efficacy objective is to demonstrate that at least 35% of subjects achieve a success rate in object recognition exceeding that expected by chance alone.
Measured: 12 months

What does the primary outcome measure?
To assess the safety of electrical stimulation on the tongue (to demonstrate no occurrence of a clinically significant device-related adverse event) (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02393118, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2016; AzTrials last refreshed its copy on 1 Nov 2026.
