Trial Summary

What is the purpose of this trial?

This trial tests if using a special enzyme can help people who have stiff arm muscles after a stroke. The enzyme works by reducing substances that cause muscle tightness, which may improve arm movement and strength. This new therapy aims to reduce muscle stiffness by breaking down certain substances in the muscles.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you have had certain treatments for muscle stiffness recently or are adjusting anti-spastic medications.

What data supports the effectiveness of the drug hyaluronidase for muscle spasms?

Research shows that hyaluronidase is effective in facilitating drug absorption and hydration in medical settings, which suggests it may help in conditions requiring enhanced tissue absorption. Additionally, it has been used successfully in the central nervous system for other conditions, indicating potential for broader therapeutic applications.12345

Is hyaluronidase generally safe for use in humans?

Hyaluronidase has been used safely for over 50 years, with recombinant human hyaluronidase showing reduced allergic risks and no allergic reactions in a study of 100 people. However, some people may develop antibodies or have allergic reactions, especially at the injection site, but serious reactions are rare.46789

How does the drug hyaluronidase work for muscle spasms?

Hyaluronidase is unique because it breaks down hyaluronan, a substance that can accumulate and cause muscle stiffness, potentially improving movement in people with muscle spasms.1011121314

Eligibility Criteria

This trial is for individuals who had a stroke 6-120 months ago and are experiencing moderate to severe muscle stiffness in their upper limb. They must be able to consent, undergo MRI scans, and follow the study's procedures. Excluded are those with recent spasticity treatments, other neurological conditions like Parkinson's or ALS, significant cognitive issues or depression, pregnancy, hyaluronidase allergy, claustrophobia or MRI contraindications.

Treatment Details

Interventions

  • Hyaluronidase
Trial Overview The trial tests human recombinant hyaluronidase injections against saline (placebo) in reducing muscle stiffness post-stroke. It's double-blind and placebo-controlled with two phases ensuring all participants receive treatment at some point over nine weeks with seven visits including MRIs before the first injection but not after the second.

Findings from Research

Hyaluronidase, an enzyme that breaks down hyaluronic acid, has shown to be well-tolerated in the human central nervous system and rabbit eyes, suggesting a potential for safe use in neurological conditions.
In three patients with hydrocephalus and related conditions, intraventricular injections of hyaluronidase effectively managed symptoms, delayed the need for shunting, and prevented fluid reaccumulation, indicating its potential therapeutic efficacy in central nervous system disorders.
Use of hyaluronidase in the central nervous system.Gegalian, L.[2004]
In a study involving 32 hospice patients over 6 months, recombinant human hyaluronidase (rHuPH20) was effectively used to enhance subcutaneous hydration and drug infusion, allowing flow rates up to 500 mL/hr without significant adverse events.
The treatment facilitated hydration for symptom control in 26 patients and improved the delivery of medications in 6 patients, indicating its potential for broader use in both inpatient and outpatient settings.
Initial experiences with subcutaneous recombinant human hyaluronidase.Pirrello, RD., Ting Chen, C., Thomas, SH.[2022]
In a study of 61 patients with severe low back pain and sciatica, the combination of hyaluronidase and triamcinolone in lumbar interlaminar epidural injection (LIEI) showed greater pain relief after 8 weeks compared to either treatment alone.
Specifically, 70.4% of patients receiving the combination treatment reported pain improvement, while only 44.4% and 31.3% improved in the triamcinolone and hyaluronidase-only groups, respectively, with significant improvement in disability scores observed only in the combination group.
