Study type | Interventional |
The purpose of this study is to determine the effects, both good and bad, of IPX056 on subjects and their spasticity. This study will also determine the relationship between the amount of IPX056 in blood and the effects on spasticity. Lastly, this study will determine how long IPX056 affects spasticity.

However, these medications will be allowed during open label study. - Unable or unwilling to participate 12-hour PK/PD procedures during Visit 1. - Treated with Botulinum Toxin Type A or B within the previous 6 months, or Phenol or therapeutic alcohol nerve block within 12 months prior to the Screening Visit. - History of alcohol abuse or use of recreational drugs within 12 months prior to the Screening Visit. - Has received an investigational drug or device within 30 days prior to the Screening Visit. - Has clinically significant limitation of passive range of motion around any of the joints being assessed in this study. - Has had major surgery within 3 months prior to Screening visit that may affect spasticity assessments such as abdominal surgery, back surgery, lower leg and knee surgeries. |
