Official title
An Open-Label, Relative Bioavailability Study Evaluating the Safety, Tolerability, and Pharmacokinetics of Ropinirole Implants in Patients With Parkinson's Disease Switched From Oral Immediate-Release Ropinirole While on L-Dopa
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Subjects stable on L-Dopa and oral ropinirole will have their ropinirole replaced with the Ropinirole Implant(s). The Ropinirole Implant was designed using the ProNeura™ implant technology where the implant is inserted under the skin. This study will measure how much ropinirole is released in the blood during 12 weeks of ropinirole implant treatment, and evaluate the side effects of this new formulation.
