The aim of this study is to test the safety and efficacy of IPX203 compared to IR CD-LD in participants with Parkinson’s disease. IPX203 is an investigational extended-release (i.e. releases drug more slowly) capsule formulation of carbidopa-levodopa (CD-LD) administered orally (by mouth).
IPX203 is being investigated to determine whether the drug is safe and potentially has a better effect than currently approved IR CD-LD. If successful, the drug could possibly improve the daily control of motor symptoms in people with Parkinson’s disease.
