Podimetrics Publishes Landmark Study Demonstrating 97% Sensitivity in Predicting Emergence of Diabetic Foot Ulcers Five Weeks Prior to Clinical Presentation


Podimetrics, Inc., a medtech and services company focused on the early
detection and prevention of diabetic foot ulcers (DFU), announced today
the publication of a landmark study in the July issue of Diabetes Care.
Results demonstrate that the Podimetrics SmartMat™ detected as many as
97% of developing nontraumatic plantar foot ulcers on average five weeks
before they presented clinically. Importantly, 86% of patients used the
mat at least three times per week and 88% of respondents reported it
being easy-to-use, suggesting that patients readily accept this
practical, new monitoring technology.

"The Podimetrics Remote Temperature Monitoring System™ could have huge
benefits for patients with diabetes who are at high risk by
significantly reducing morbidity and mortality associated with diabetic
foot ulcers, which could also lead to improvements in resource
utilization," said Dr. Robert Frykberg, Chief of the Podiatry Section in
the Dept. of Surgery at the Carl T. Hayden Veterans Affairs Medical
Center and Professor at the University of Arizona College of Medicine,
Phoenix, and lead investigator.

"These data reinforce our belief that the Podimetrics Remote Temperature
Monitoring System™, which consists of a wireless SmartMat™ for the home
and a full monitoring and notification service, may allow earlier
detection of DFU and significant improvements in care," said Jon Bloom,
MD, CEO of Podimetrics. "When we developed our system, it was clear that
patients wanted an easy-to-use, in-home solution. This study
demonstrates that patients find the Podimetrics SmartMat™ easy-to-use
and that 86% of the population used it at least three times per week on
average - which is critical for adherence and ultimately achieving
ongoing prevention of DFU and its devastating complications."

Study Design and Results
The study was a 34-week,
multi-center evaluation of the Podimetrics Remote Temperature Monitoring
System™ in 129 participants with diabetes and prior DFU. The primary
outcome of interest was development of nontraumatic plantar DFU, and the
primary efficacy analysis was the accuracy of the Podimetrics SmartMat™
for predicting the occurrence of DFU over several temperature asymmetry

Of the 129 participants who contributed evaluable data to the study, a
total of 37 (28.7%) presented with 53 DFU (0.62 DFU/participant/year).
At a temperature asymmetry threshold of 2.22°C, which is the standard
threshold used in previous plantar thermometry studies, the system
correctly identified 97% of observed DFU, with an average lead time of
37 days. Increasing the temperature threshold to 3.20°C decreased
sensitivity to 70% but reduced the false-positive rate from 57% to 32%
with approximately the same lead time of 35 days. Approximately 86% of
the cohort used the system at least 3 days a week on average over the

"The false positive rate observed in this study was not surprising or
concerning," continued Dr. Frykberg. "This is particularly true given
that the value of preventing a foot ulcer and its complications far
outweighs the nuisance factor of a false alert. In a real-world setting,
when a doctor gets a notification that a patient has a hotspot, the
patient will be advised to reduce physical activity for a period to let
the developing wound heal or may be asked to come in for a visit in
serious cases. Even at the most sensitive setting presented in the
study, these results translate to only 3.1 total notifications to the
physician and patient per year, including all true and false positives."

The Podimetrics Remote Temperature Monitoring System™
Podimetrics Remote Temperature Monitoring System™ consists of a wireless
SmartMat™ for the home and a monitoring service that notifies patients
and clinicians when signs of inflammation may be developing. To use the
system, a patient stands on the mat for 20 seconds per day at home.
Patient data is sent instantly to the cloud, where the Podimetrics
system automatically measures the temperature difference between the
feet at various locations looking for a possible persistent asymmetry,
or "hotspot." It has been well established that these hotspots strongly
correlate with the eventual development of a foot ulcer. If a developing
hotspot is detected, the healthcare provider is notified based on their
custom protocol. From there an intervention is planned by the physician.
Most interventions require a patient to stay off his/her feet while the
foot heals itself. If the readout is persistent or more concerning, the
patient may visit their doctor to take more aggressive preventative

The Podimetrics system is easy-to-use for healthcare providers as the
solution is tailored to meet the needs of each specific care environment
via close collaboration.

About Diabetic Foot Ulcers
Diabetic Foot Ulcers (DFU) are
common and expensive complications of diabetes which can result in
amputation in serious cases. Approximately 1.7 million Americans suffer
from one or more DFU each year. Though all patients with diabetes are at
risk for developing a DFU, those patients who have recently healed from
a previous DFU episode have approximately a 40% likelihood of recurrence
in the first year after closure. It is estimated that direct costs
associated with DFU exceed $17 billion annually.

About Podimetrics
Podimetrics is a medtech and services
company focused on the commercialization of next-generation
hardware-enabled, thermo-imaging solutions for the prediction and
prevention of diabetic foot ulcers. The Podimetrics SmartMat™ is the
only remote temperature monitoring technology that has received FDA
clearance, and has been in over 650 patient homes. The Podimetrics
Remote Temperature Monitoring System™ consists of a wireless SmartMat™
for the home and a monitoring service that notifies patients and
clinicians when temperature asymmetry presents between the two feet, a
potential sign of inflammation and a developing foot ulcer. Podimetrics
was formed out of the Massachusetts Institute of Technology in 2011 and
is based in Somerville, MA.
