The First Relief percutaneous neurostimulation device can be used to treat pain related to diabetic neuropathy. It is applied behind the ear and delivers continuous pulses of a low-level electrical current over several days.

"We are excited to have the FDA clearance of First Relief so that this device, which has been proven effective, can now be used to treat patients who have been experiencing pain related to diabetic neuropathy," said DyAnsys CEO Srini Nageshwar. "First Relief offers a significant treatment option without drugs or narcotics."

According to a press release, the approval was based on a study that tested First Relief against a placebo and another device previously cleared by the US Food and Drug Administration. The study was conducted at the Jeevak Multispeciality Hospital in Warangal, India, renowned for the treatment of diabetes. The single-center, three-arm, randomized, controlled, parallel assignment, double-blinded, prospective study involved 63 patients aged 30 to 74.

The devices were applied on a bi-weekly basis for 16 weeks. The primary efficacy endpoint was pain intensity measured through the Visual Analog Scale (VAS) score and the secondary efficacy endpoints are vibration perception threshold (VPT) value, insomnia severity index (ISI), overall neuropathy limitations scale (ONLS), and Hamilton rating scale for anxiety.

The VAS pain score analysis showed a significant reduction in the pain score of patients being treated with First Relief from the start of the treatment to the end. This improvement persisted throughout the 90-day follow-up, suggesting that the treatment was a long-term improvement in neuropathic pain and not a short-term improvement. The secondary outcome measures (VPT, Insomnia, ONLS, and HAM) also showed similar improvements to the pain score, showing significant improvement in sleep and mood as the neuropathic pain decreased.

No complications or adverse events were observed in any of the subjects during the study period.
