Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Must have a score on the Modified Ashworth Scale of 2 or more in the targeted area (shoulder and elbow) at Screening and at Baseline (Day-1 pretreatment)
A diagnostic nerve block using lidocaine (1% lidocaine, 2 to 3 mL per target nerve) showing a positive response (at least one point reduction from the screening Modified Ashworth Scale score for elbow extension and shoulder abduction) to the targeted nerves, should be performed within 30 days to at least 6 hours before study treatment. The diagnostic nerve block effect must be completely resolved before pretreatment evaluation and the study treatment
Must not have
Diagnosis of cryoglobulinemia, paroxysmal cold hemoglobinuria, cold urticaria, or Raynaud's disease
Any hospitalization within 4 weeks before Screening
Timeline
Screening 3 weeks

Pivotal Trial

Summary

This trial will test a new system called iovera° for treating upper extremity spasticity. They will enroll 132 subjects and randomly assign them to receive either the iovera° treatment

Who is the study for?
This trial is for adults with cerebral palsy or muscle spasms causing stiffness in the shoulder and elbow. Participants must have been diagnosed at least 6 months prior, not be on varying oral spasticity meds, or if using a baclofen pump, it should be stable for six months. They need to show improvement after a lidocaine nerve block test.
What is being tested?
The study tests the iovera° system's effectiveness and safety against sham treatment in reducing upper extremity spasticity. Of the participants, two-thirds will receive actual iovera° treatment while one-third will get a sham procedure, decided randomly.
What are the potential side effects?
While specific side effects are not listed here, typical risks may include pain at the treatment site, potential nerve injury from incorrect application of the system or device malfunctioning.
