Nevro Responds to Competitor's Announcement of FDA Approval for Painful Diabetic Neuropathy

January 25, 2022

REDWOOD CITY, Calif., Jan. 25, 2022 /PRNewswire/ -- Nevro Corp. (NYSE: NVRO), a global medical device company that is delivering comprehensive, life-changing solutions for the treatment of chronic pain, today responded to Medtronic's announcement of FDA approval for painful diabetic neuropathy (PDN).

"PDN represents a very large potential market, and having another competitor validate this large opportunity speaks to its attractiveness," stated D. Keith Grossman, Chairman, CEO and President of Nevro.  "We are very proud of our SENZA-PDN study, the largest, prospective SCS trial conducted for this patient population, generating Level 1 clinical data that we believe has moved the field and the therapy forward.  The trials presented by our competitor to support its FDA submission makes especially clear that our proprietary, paresthesia-free 10 kHz Therapy is uniquely suited to treat PDN patients.  In fact, a recent review of spinal cord stimulation evidence for painful diabetic neuropathy concluded, 'High-frequency 10 kHz SCS offers several advantages over low frequency SCS, including greater pain relief, a higher proportion of patients achieving treatment success, paresthesia-independence, and evidence of improved neurological function. Neuromodulation with SCS, especially with 10 kHz SCS, offers a pathway forward for improving the lives of PDN patients.'"1

Dr. David Caraway, Nevro's Chief Medical Officer added, "Instead of the large clinical trial it has been promising to the Pain and Diabetes clinical communities for these patients, Medtronic has simply reintroduced two small European studies from 2014.2,3  One of these studies was actually sponsored by another competitor and did not even use Medtronic's products.2  Both of these low-frequency, SCS trials required paresthesia delivery and demonstrated results that were dramatically inferior to the outcomes generated in our landmark SENZA-PDN trial, a fact widely recognized by our clinicians since the publication of the SENZA-PDN trial results.  Unfortunately, these much smaller trials provide no new evidence to further advance the field, drive adoption or expand payer coverage.  We believe the significant, durable outcomes from our SENZA-PDN randomized, controlled trial speak for themselves, and we are disappointed in the disparity of standards supporting these two FDA approvals." 

Nevro's landmark SENZA-PDN randomized, controlled trial (RCT), using 10 kHz high frequency, is the first spinal cord stimulation system approved by the FDA with a specific indication to treat PDN and has demonstrated significant benefits for SCS therapy to treat PDN patients.4,5  The 2014 Slangen study submitted by Medtronic to support their FDA submission is the only published RCT using Medtronic devices. Differences in this and the Senza-PDN include:

  • The SENZA-PDN study randomized 216 patients with 113 patients assigned to the SCS arm and 154 implanted after crossover.  In the Medtronic sponsored Slangen study, 36 patients were randomized and only 22 were assigned to the SCS group.  In total, 17 patients received permanent SCS device implants and only 16 completed the RCT with 15 available for 24-month follow-up;6  
  • Medtronic's press release on 1/24/22 stated, "70% of patients receiving treatment with SCS experienced relief of their pain symptoms."  However, the intention to treat (ITT) pain responder rate (using the 50% pain relief industry standard) at the end of the 6-month RCT was reported in the Medtronic sponsored study as 9/22 (41%) for daytime pain and only 8/22 (36%) for night time pain.  In the SENZA-PDN RCT, 75/104 (72%) of patients were overall pain responders. Using the same comparator, this two-fold difference leads to a number needed to treat (NNT) of 2.4 and 3.4 (day and night, respectively), for the Medtronic device as compared to only 1.5 for 10 kHz SCS;
  • SENZA-PDN demonstrated average pain relief of 75% at 18 months vs. 46% at 24 months in the Slangen study;6  10 kHz Therapy is the only device to demonstrate improvement in neurological function, with two-thirds of 10 kHz patients reporting improvement, including restoration of sensation.  There was no evidence of neurological improvement reported in the Slangen study;
  • SENZA-PDN RCT demonstrated a clinically and statistically significant improvement in Health-Related Quality of Life (HRQoL).  The Medtronic device showed no improvement in HRQoL or EQ5D measures in the Slangen study;
  • In the Senza-PDN study, there were no explants due to loss of efficacy or battery depletion.  In the Slangen study, 33% of devices required replacement due to battery depletion at 5 years.
