Resting tremors occur in more than 70% of patients with advanced Parkinson's disease (PD). PD patients with resting tremors are typically treated with oral dopaminergic therapy or non-dopaminergic agents. However, treatment response with these medications is inconsistent and often unsatisfactory. Levodopa-carbidopa intestinal gel (LCIG, also known in the United States as carbidopa-levodopa enteral suspension (CLES)), administered continuously by a portable pump via a percutaneous endoscopic gastrojejunostomy (PEG-J) tube, significantly improves motor complications in patients with advanced PD. This was a post hoc analysis of a large phase 3, 12-month, open-label study evaluating long-term safety and efficacy of LCIG via PEG-J tube (NCT00335153). Unified Parkinson's Disease Rating Scale Part III Question 20 total scores at baseline, measuring resting tremors, were used to stratify patients into three subgroups (none, mild, or significant baseline resting tremors). Out of 354 enrolled patients, 286 had baseline and post-PEG-J assessments of resting tremors and were included in this analysis. At baseline the majority of patients (69%) had no resting tremors, whereas 13% had mild resting tremors, and 18% had significant resting tremors. A complete resolution in resting tremors after 12 months of LCIG treatment was reported for 78% and 70% of patients with mild and significant baseline resting tremors, respectively. Improvements in motor complications and quality of life occurred regardless of degree of baseline resting tremors. LCIG may provide more consistent and sustained improvements in resting tremors that were not well-controlled with optimized oral medication among patients with advanced PD.
