Another Spinal Cord Stimulation System Gets Pain Indication

Nevro Corporation has received approval from the U.S. FDA for its Senza spinal cord stimulation (SCS) system for the treatment of chronic pain.


A few weeks ago we covered the approval of St. Jude’s Prodigy Spinal Cord Stimulator for use in treatment of chronic intractable pain. Now along comes Nevro’s Senza system, although it was approved in Europe and Australia five years ago.

The Senza system delivers HF10 therapy and is indicated as an aid in the management of chronic intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with failed back surgery syndrome, intractable low back pain and leg pain.

The FDA approval now means patients in the U.S. suffering from chronic pain will have the opportunity to experience the significant benefits of HF10 therapy.

Nevro’s press release announcement points out that HF10 therapy is the only SCS therapy approved by FDA with superiority labeling, the only SCS therapy indicated by FDA to deliver pain relief without paresthesia and that HF10 therapy is the only SCS therapy approved by FDA to be used without patient restrictions on motor vehicle operation while receiving therapy.

The “superiority” labeling was based on the SENZA-RCT clinical trial, where HF10 therapy was meaningfully superior to traditional SCS therapy for back and leg pain, including superior response rates, pain relief, and functional outcomes. Superiority was demonstrated in the primary and all secondary endpoints including at every measurement time point throughout the 12 month follow up.

The Senza system is the only implantable SCS system approved by FDA with labeling for 3T conditional MRI compatibility.

The Senza system was the subject of the SENZA-RCT pivotal study, a ground-breaking study that was the first to directly compare SCS therapies. The multicenter study was conducted across 11 U.S. clinical trial sites, comparing the safety and effectiveness of HF10 therapy to traditional SCS therapy. The study enrolled 241 patients, making it the largest prospective randomized SCS study ever conducted to assess the treatment of chronic back and leg pain.

Investigator comments

“My fellow investigators and I have eagerly awaited the approval of the Senza SCS system,” said Dr. Leonardo Kapural, lead investigator for the SENZA-RCT pivotal study from Wake Forest University Baptist Medical Center. “The results of the study showed that HF10 therapy provides better pain relief and nearly twice the response rate of traditional SCS, representing a tangible advance in chronic pain management. HF10 therapy will allow me to help more patients in my practice by addressing back pain in addition to leg pain. And, with HF10 therapy I can for the first time focus on providing pain relief to my patients instead of managing paresthesia, which is a paradigm shift for my pain practice.”

Company comments

“We are grateful to the inspiring dedication of the clinical investigators, their study coordinators, and patients involved in the SENZA-RCT study, as they collectively have paved the way for this therapy to help those suffering from debilitating chronic pain,” said Michael DeMane, Chairman and Chief Executive Officer of Nevro. “The Nevro organization is prepared to initiate a responsible rollout of HF10 therapy to the U.S. pain management community and the patients they serve to ensure we deliver the clinical outcomes that are the foundation of our therapy and company.”
