Study summary

Levodopa-Carbidopa intestinal gel (LCIG) is an effective therapy for complicated Parkinson's disease (PD). Few studies have explored the efficacy and safety of the potential combination of LCIG with catechol-O-methyltransferase (COMT) inhibitors, particularly Opicapone (OPC).

Read the detailed description

22 PD patients were randomized into LCIG monotherapy (n-OPC 11 patients) and LCIG+OPC (add-OPC 11 patients), further divided according to OPC adding time (E-OPC within one month and L-OPC after one month from LCIG implant).

Data on PD clinical aspects, Montreal Cognitive Assessment (MoCA), Unified Parkinson's Disease Rating Scale (UPDRS), Unified Dyskinesia Rating Scale (UDysRS), electroneurography (ENG), and pharmacological therapy (Levodopa Equivalent Dose-LEDD) were collected before LCIG implanted (T0) and in the following 12 (T1) months.
