Injection Therapy for Neuropathic Pain

Status Completed

Clinical Trial Summary

Shoulder, neck, back and temporal pain and herpes zoster pain are neuropathic pain. Preliminary clinical studies have confirmed that injection of freshly prepared HA35 can relieve neuropathic pain. This clinical study is a prospective repeated experiments. The purpose of this study was to verify the effectiveness of HA35 injection therapy.

Clinical Trial Description

In this study, the recombinant human hyaluronidase PH20 and neutral hyaluronidase (PH20) of bovine testicular sperm acrosomes were used to cleave macromolecular HA. Regardless of the cutting time, the HA fragment HA35, with an average molecular weight of 35 kDa, was produced (Registration number L20200708MP07707, Ministry of Health, Mongolia). Hyaluronidase is often used to improve the penetration and absorption of other injectable drugs. Hyaluronidase injection is also used off label to degrade excessive components used in cosmetic injections, such as cross-linked macromolecular HA fillers (https://www.realself.com/news/hyaluronidase-dissolve-fillers). In this study, HA35 was prepared by mixing hyaluronidase extracted from bovine testis (hyaluronidase for injection, H31022111) and HA (sodium hyaluronate for injection, H20174089) at room temperature for 20 minutes. The analgesic effect of HA35 on herpes zoster and shoulder, neck, back, and temporal pain was studied. This was a single-arm, open-label prospective clinical study in which patients were evaluated before and after treatment. ;
