Saluda Medical Announces Clinical Study Results for Evoke(R) ECAP-Controlled, Closed-Loop SCS System for the Treatment of Chronic Pain
ARTARMON, Australia, June 3, 2019 /PRNewswire-AsiaNet/ --

--New Results Highlight the Importance of Objective Neurophysiological Measures 
and Clinically Meaningful Functional Outcomes 

Saluda Medical Pty Limited ("Saluda Medical") today announced data from two 
clinical studies evaluating the performance of the company's Evoke(R) 
ECAP-Controlled, Closed-Loop Spinal Cord Stimulation (SCS) System and its 
impact on pain relief for patients suffering from chronic pain. Evoke is 
designed to be the first closed-loop SCS system that measures the spinal cord's 
response to stimulation (via ECAPs, or evoked compound action potentials) and 
adjusts on every pulse to maintain activation within the patient's therapeutic 
window.

Results were reported in multiple plenary and oral presentations by leading 
pain specialists during the International Neuromodulation Society (INS) 14th 
World Congress in Sydney.

The Evoke and Avalon studies both demonstrated improvements in pain, function, 
sleep, and quality of life. These data substantiate the observation that 
considerable pain relief can impact a patient's entire life, including 
reduction in pain medications. 

Steven M. Falowski, M.D., Director of Functional Neurosurgery at Neurosurgical 
Associates of Lancaster in Lancaster, PA and an investigator in the Evoke 
Study, said, "Two separate studies of the Evoke System show promising results. 
The U.S. Evoke study, the first double-blind randomized regulatory approval 
study in SCS, demonstrated better rates in pain relief and secondary outcomes 
for closed-loop compared to control. The Avalon study, an Australian 
prospective, single-arm study, provides long-term evidence for sustained pain 
relief with closed-loop. Both studies provide evidence supporting the novel 
design of the device where ECAPs are measured to monitor therapy delivery in 
real time. The technology provides an objective measure based on a 
neurophysiological response to control therapy delivery and provides insight 
into the mechanism of action. There were a plethora of talks featuring ECAPs at 
this congress and they highlight the potential clinical utility of this new 
technology." 

Dr. Charles Brooker, Director of the Pain Management and Research Centre, Royal 
North Shore Hospital and Principal Investigator in the Avalon Study, 
highlighted, "With Evoke, study results suggest that pain relief continues to 
improve over time, which is not typically observed with fixed-output systems. 
With the capability of neurophysiology measurements, such as percentage time in 
the therapeutic window, we can now start to understand a complex condition 
objectively in addition to patient reported outcomes, an important advancement 
to the field of pain management."  

Key results presented at the congress from the Evoke U.S. Pivotal Study at 3 
months include: 

  --Closed-loop met all pre-specified endpoints. 
  --Closed-loop demonstrated statistically superior back and leg pain relief
    (with no increase in pain medications) compared to control with more than
    80% (82.3% [51/62]) of closed-loop subjects achieving greater than or equal
    to 50% pain relief (control: 60.3% [38/63]). 
  --More than half of closed-loop subjects (58.1% [36/62]) were high responders
    with greater than or equal to 80% reduction in back and leg pain (control:
    42.9% [27/63]).  
  --Closed-loop maintained spinal cord activation within the therapeutic window
    1.5x that of the control group (91.1% of the time with closed-loop vs.
    59.5% of the time with control).

Key results presented at the congress from the Avalon Australian Study at 18 
months include: 

  --More than 2 out of 3 patients (69.4% [25/36]) experienced more than 80%
    pain relief. 
  --More than 8 out of 10 patients (83.3% [30/36]) experienced clinically
    meaningful improvement in quality of life. 
  --Disability was also reduced, with more than 7 out of 10 patients (72.2%
    [26/36]) having only minimal to moderate disability compared to 18.0%
    [9/50] at baseline. 
  --More than 2 out of 3 patients (67.9% [19/28]) reduced or eliminated opioid
    medications. 
  --Spinal cord activation was maintained within the therapeutic window 97.5%
    of the time. 

About Saluda Medical
Saluda Medical is a global medical device company focused on patient outcomes, 
science, and engineering to transform the neuromodulation industry with a 
platform of closed-loop technologies based on the evoked compound action 
potential (ECAP). Saluda's first device, Evoke(R), is designed to be the first 
Closed-Loop Spinal Cord Stimulation (SCS) System. Evoke measures the spinal 
cord's response to stimulation (ECAP), adjusts on every pulse to optimize 
activation within the patient's therapeutic window, and is designed to maintain 
long-term results through ECAP control. It is currently under investigation 
through the first double-blinded, randomized, controlled U.S. pivotal study in 
SCS. Saluda is pursuing CE Mark, TGA approval, and FDA approval of Evoke.

Saluda Medical is a privately-held company with headquarters in Artarmon, New 
South Wales, Australia and offices in Bloomington, MN, USA and Harrogate, UK.
