Clinical Experience
The BrainPort V100 device was evaluated in a single arm,
open label clinical study of 75 enrolled blind/profoundly
blind subjects from 7 s ites i n the U .S. and C anada.
Subjects unde rwent 2 -3 day s ( 10 ho urs) o f tra ining
followed by in-home use over the span of 12 months for
the study.
The p rimary s afety endpoint was no o ccurrence o f a
clinically s ignificant device-related a dverse e vent. A
clinically s ignificant device-related adv erse e vent wa s
defined as any e vent that resulted i n to ngue b urns
attributed to use of the BrainPort V100 device, an allergic
reaction requiring medical care, or negatively altered
changes in taste or numbness that was sustained and/or
resulted in withdrawal from the study. The primary
efficacy e ndpoint w as su ccess i n a t est of ob ject
recognition of at least 50%. The secondary endpoints
measured success rates of at least 50% in tests of word
identification a nd at l east 3 5% i n s ign identification i n a
mobility task. Effectiveness e ndpoints we re m easured at
12 month follow up, and safety events were captured
throughout the study.
Study results demonstrated that the safety objective was
achieved, with no clinically significant d evice-related
adverse e vents thro ughout the s tudy. There w ere n o
serious device-related adverse events. Two (2.67%) of

BrainPort V100 User Manual 14
the s tudy s ubjects re ported m ild/moderate e vents
possibly/probably related to the device that led to
decrease i n d evice u se or d iscontinuation of d evice u se.
One subject reported worsening sinus drainage that was
considered a po ssible m etal a llergy and p ossibly re lated
to the device. Device use was discontinued for this
subject. One subject reported tongue soreness that wa s
considered pro bably related to the de vice. D evice us e
decreased for this subject. Both subjects recovered. For
a complete list of device-related adverse e vents that
occurred in the clinical study of the device, see Appendix
B.
In te rms o f e ffectiveness, the pri mary e fficacy o bjective
was achieved with more than 50% of subjects achieving
success o n the object re cognition tas k. Results o f the
secondary efficacy endpoints similarly confirmed device
performance, where approximately 44% of subjects were
able to successfully complete the word identification and
mobility tasks (where subjects with missing data were
counted as failures for a conservative analysis). Based on
all av ailable data at the e nd o f the s tudy, i.e., the “pe r
protocol” subjects who completed 12 month follow up,
57.9% of the study subjects successfully completed the
word identification and mobility tasks.
Overall, evaluation of the safety and efficacy of the
BrainPort V100 device demonstrated a low-risk safety
profile with no serious device-related adverse events, and
strong effectiveness results confirming d evice
performance in the intended user population.
