An interventional study of HA35(L20200708MP07707, Ministry of Health, Mongolia) was freshly manufactured by mixing hyaluronidase PH20 injectable solution (H31022111) and high-molecular-weight HA injectable solution (H20174089) in Shoulder Pain, Neck Pain and Back Pain, sponsored by Dove Medical Press Ltd. Completed at 1 site in China. Open to participants aged 39 Years to 63 Years. Per ClinicalTrials.gov, last updated 2023-03-06.

Local used high molecular weight Hyaluronan (HA) with high viscosity has a variety of receptors in the human body, including CD44, LYVE-1, RHAMM, HARE, Siglec-9, TLR2, CEMIP and TMEM2. Intra-articular local injection of HA has a certain degree of analgesic effect. Local injection of HA into the nerve trunk directed by ultrasound was used for the treatment of neuropathic pain. It was reported that the analgesic effect of HA is regulated by TRPV1 ion channels. This study hypothesizes that hyaluronidase cleaves HA to generate low molecular weight HA fragments HA35 with good tissue permeability, which may bind to a variety of HA receptors on the cell surface within the tissues and produce a broad-spectrum analgesic effect. In this study, 35kDa Hyaluronan fragment HA35 was prepared by mixing hyaluronidase PH20 injection and high molecular weight Hyaluronan (HA) injection at room temperature for 20 minutes. In this study, hyaluronidase injection and Hyaluronan injection were off-label used to conduct an investigator-initiated study (IIT or IIS) for the treatment of herpes zoster and shoulder, neck, back and temporal pain.
Bioactive Hyaluronan fragment HA35 of 35kDa was isolated from human colostrum. Literature studies have shown that female breast hyaluronidase and male testicular sperm acrosomal hyaluronidase PH20 come from the same gene. The investigators, recombinant human hyaluronidase PH20 and neutral hyaluronidase (PH20 or SPAM1) of bovine testicular sperm acrosome were used to cleave macromolecular Hyaluronan. Regardless of the cutting time, the Hyaluronan fragment HA35 with an average molecular weight 35kDa was produced(Registration number L20200708MP07707, Ministry of Health, Mongolia). Hyaluronidase injection is often used to improve the penetration and absorption of other injectable drugs. Hyaluronidase injection is also used to degrade excessive use of cosmetic injection or improper use of cross-linked macromolecular Hyaluronan fillers, which is an off-label drug use of hyaluronidase（https://www.realself.com/news/ hyaluronidase-dissolve-fillers）. In this study, Hyaluronan fragment HA35 of 35kDa was prepared by mixing hyaluronidase injection extracted from bovine testis (hyaluronidase for injection, H31022111) and Hyaluronan injection (sodium hyaluronate injection, H20174089) at room temperature for 20 minutes. Its analgesic effect on herpes zoster, shoulder, neck, back, and temporal pain was studied.
In this study, off-label drug use of hyaluronidase injection and Hyaluronan injection （https://www.realself.com/news/ hyaluronidase-dissolve-fillers）were used in the clinical study of shoulder, neck, back and temporal pain and herpes zoster pain, namely investigator initiated trails. In this clinical trial, 26 patients with shoulder, neck, back and temporal pain were studied in the Department of pain diagnosis and treatment of the affiliated Hospital of Qingdao University. Ten patients with herpes zoster were treated in the pain Department of the affiliated Hospital of Qingdao University. According to the ratio of 100mg high molecular Hyaluronan / 2000 unit hyaluronidase, the high molecular Hyaluronan injection (sodium hyaluronate injection, H20174089) and the hyaluronidase injection extracted from bovine testis (hyaluronidase for injection) were mixed at room temperature for 20 minutes. Each time according to the amount of high molecular Hyaluronan containing 100 mg Hyaluronan and hyaluronidase mixture, pain point area and pain point area of the nerve trunk innervation of the local multi-point injection. Then, pain scale was used to evaluate and record the pain relief of patients before and after treatment.

Exclusion Criteria:
100 mg Hyaluronan is locally injected at the pain point or where the nerve trunk is innervated by the pain point.
Drug: HA35(L20200708MP07707, Ministry of Health, Mongolia) was freshly manufactured by mixing hyaluronidase PH20 injectable solution (H31022111) and high-molecular-weight HA injectable solution (H20174089)
This group will inject once a week. Evaluation of pain score after 30 seconds and 3 hours.
Also known as: HA35
Pain scores of all shoulder, neck, back, temporal and herpes zoster pain
The pain scale is a tool that doctors use to help assess patients' pain. Each patient rated their pain on a scale of 0 to 10. 0 means "no pain" and 10 means "the most painful". Statistical t-test was used to calculate and evaluate the pain intensity, which was expressed as mean ±standard deviation.
