Running, not enrolling · Not applicable · Has a placebo group

Conditions studied: Spasticity, Cerebral or Spinal Condition

In brief

This multicenter, randomized, double-blind, sham-controlled study is designed to evaluate the efficacy and safety of the iovera° system in subjects with upper extremity spasticity. A total of approximately 132 subjects will be enrolled; 88 subjects will receive treatment with the iovera° system and 44 subjects will receive sham treatment (sham iovera° system treatment).

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female, 18 years and above.
• A confirmed diagnosis of any cerebral or spinal condition, at least 6 months before Screening, resulting in spasticity of the muscles controlling the shoulder and elbow.
• Not on oral medications for spasticity management or if on any oral medications, the oral medication taken chronically for spasticity management (eg, oral baclofen) must be maintained at a stable dose for at least 4 weeks before screening for the study.
• Not on an intrathecal baclofen pump or if on an intrathecal baclofen pump for spasticity management, must be maintained at a stable dose for six months or more before screening for the study.
• 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.
• Subject, in the investigator's opinion, will not be exposed to unacceptable risk by participation.
• Able to provide informed consent, adhere to the study schedule, and complete all study assessments.

• History of neurotoxin injections within the past 3 months.
• Previous injection with phenol or ethyl alcohol at any time in the target areas (shoulder or elbow).
• Previous surgical intervention that altered the target neuroanatomy of the upper limb.
• Current or planned enrollment in an investigational drug or device study for the management of spasticity for the duration of the study.
• Medical instability that interferes with tolerability to spasticity treatment with the study device as per the investigator's discretion.
• Any hospitalization within 4 weeks before Screening
• Diagnosis of amyotrophic lateral sclerosis or any lower motor neuron conditions
• Allergy or intolerance to amide local anesthetics.
• Any skin condition in or around the target area that, in the opinion of the investigator, could adversely impact treatment.
