Project description:ObjectiveThe purpose of this study was to assess the effect of levodopa-carbidopa intestinal gel (carbidopa-levodopa enteral suspension) in advanced Parkinson's disease patients with troublesome dyskinesia.MethodsPost hoc analyses of patient data from a 12-week, randomized, double-blind study and a 54-week open-label study were performed. Efficacy was assessed in the subgroup of patients defined by ?1 hour of "on" time with troublesome dyskinesia at baseline as recorded in Parkinson's disease symptom diaries (double blind: n?=?11 levodopa-carbidopa intestinal gel, n?=?12 oral levodopa-carbidopa; open label: n?=?144 levodopa-carbidopa intestinal gel). The changes in "off" time, "on" time with and without troublesome dyskinesia, and the overall safety and tolerability of levodopa-carbidopa intestinal gel were analyzed.ResultsAlthough not significantly different from oral levodopa treatment (P?>?.05) in the double-blind study, levodopa-carbidopa intestinal gel treatment resulted in a reduction from baseline in "on" time with troublesome dyskinesia (mean [standard deviation] hours: baseline?=?3.1 [1.7], change from baseline to final?=?-1.8 [1.8], P?=?.014), increase in "on" time without troublesome dyskinesia (baseline?=?7.4 [2.2], change?=?4.4 [3.6], P?=?.004), and decrease in "off" time (baseline?=?5.5 [1.3], change?=?-2.7 [2.8], P?=?.015). Similar trends were found in the open-label study. An increase in levodopa-carbidopa intestinal gel dose was not significantly correlated with increased "on" time with troublesome dyskinesia in either study (double blind: r?=?-.073, P?=?.842; open label: r?=?-0.001, P?=?.992). Adverse events were usually mild to moderate in severity and related to the gastrointestinal procedure.ConclusionOur exploratory analyses suggest that optimizing levodopa delivery with levodopa-carbidopa intestinal gel may reduce troublesome dyskinesia in advanced Parkinson's disease.

Project description:BackgroundThere are limited data regarding the effectiveness of levodopa-carbidopa intestinal gel (LCIG) for dyskinesia.ObjectiveCompare the effectiveness of LCIG versus oral optimized medical treatment (OMT) for dyskinesia in patients with advanced Parkinson's disease (PD) using the Unified Dyskinesia Rating Scale (UDysRS).MethodsThis phase 3b, open-label, multicenter, 12-week, interventional study (NCT02799381) randomized 63 LCIG naïve patients with advanced PD (UDysRS ≥30) to LCIG (N = 30) or OMT (N = 33) treatment. Dyskinesia impact was assessed at baseline through week 12 using the UDysRS. PD-related motor and non-motor symptoms, and quality of life (QoL) were also assessed.ResultsDyskinesias measured by UDysRS were significantly reduced in the LCIG group (n = 24; -17.37 ± 2.79) compared with the OMT group (n = 26; -2.33 ± 2.56) after 12 weeks (-15.05 ± 3.20; 95% CI, -21.47 to -8.63; P < 0.0001). At week 12, LCIG versus OMT also demonstrated significant improvements in "On" time without troublesome dyskinesia (P = 0.0001), QoL (P < 0.0001), global impression of change (P < 0.0001), activities of daily living (P = 0.0006), and Unified Parkinson's Disease Rating Scale (UPDRS) Part III (P = 0.0762). Treatment-emergent adverse events were reported in 27 (44.3%) patients (LCIG, 18 [64.3%]; OMT, 9 [27.3%]). Serious adverse events occurred in 2 (7.1%) LCIG-treated patients.ConclusionsLCIG significantly reduced dyskinesia compared with OMT. LCIG showed efficacy for treatment of troublesome dyskinesia in patients with advanced PD while demonstrating benefits in both motor and non-motor symptoms and QoL. © 2021 AbbVie Inc.

Project description:BackgroundLevodopa-carbidopa intestinal gel (LCIG) treatment has shown variable effect on dyskinesia in Parkinson's disease (PD).ObjectiveTo identify PD patients who are likely to have troublesome dyskinesia under LCIG treatment and describe the pharmacokinetic-dynamic profile and dyskinesia phenomenology of those patients.MethodsPD patients were assessed for clinical and therapeutic variables, before LCIG treatment (T0) and at last outpatient visit (T1). Sub-groups of patients with and without "troublesome dyskinesia" (UPDRS IV, item 33 ≥2), matched for disease and LCIG treatment duration, underwent a pharmacokinetic-dynamic assessment.ResultsWe included 53 PD patients. After a mean of 51.7 ± 34.1 months of LCIG treatment, "off-time" was significantly reduced, whereas, dyskinesia duration/disability did not change. The multivariate regression model, adjusted for LCIG treatment duration, showed that being female increases the risk of presenting troublesome dyskinesia at T1 (odds ratio [OR] = 9.2; 95% confidence interval [CI] = 2.4-37.4) that was also significantly associated to longer off periods at T1 (OR= 4.4; 95% CI = 1.1-14.3). Female patients showed a higher risk for a higher dyskinesia score at T1 (sum of the items 32 and 33: P = 0.001). Patients with troublesome dyskinesia showed a tendency for a lower motor benefit and the appearance of more severe dyskinesia despite similar levodopa plasma concentration.ConclusionDyskinesia should be carefully monitored in patients undergoing LCIG, with particular caution for female patients. Whether combined clinical and pharmacodynamic assessments could be helpful to manage patients with troublesome dyskinesia under LCIG treatment needs further evaluation in a larger group of patients.

Project description:Levodopa-carbidopa intestinal gel (LCIG) delivered continuously via percutaneous endoscopic gastrojejunostomy (PEG-J) tube has been reported, mainly in small open-label studies, to significantly alleviate motor complications in Parkinson's disease (PD). A prospective open-label, 54-week, international study of LCIG is ongoing in advanced PD patients experiencing motor fluctuations despite optimized pharmacologic therapy. Pre-planned interim analyses were conducted on all enrolled patients (n = 192) who had their PEG-J tube inserted at least 12 weeks before data cutoff (July 30, 2010). Outcomes include the 24-h patient diary of motor fluctuations, Unified Parkinson's Disease Rating Scale (UPDRS), Clinical Global Impression-Improvement (CGI-I), Parkinson's Disease Questionnaire (PDQ-39), and safety evaluations. Patients (average PD duration 12.4 yrs) were taking at least one PD medication at baseline. The mean (±SD) exposure to LCIG was 256.7 (±126.0) days. Baseline mean "Off" time was 6.7 h/day. "Off" time was reduced by a mean of 3.9 (±3.2) h/day and "On" time without troublesome dyskinesia was increased by 4.6 (±3.5) h/day at Week 12 compared to baseline. For the 168 patients (87.5%) reporting any adverse event (AE), the most common were abdominal pain (30.7%), complication of device insertion (21.4%), and procedural pain (17.7%). Serious AEs occurred in 60 (31.3%) patients. Twenty-four (12.5%) patients discontinued, including 14 (7.3%) due to AEs. Four (2.1%) patients died (none deemed related to LCIG). Interim results from this advanced PD cohort demonstrate that LCIG produced meaningful clinical improvements. LCIG was generally well-tolerated; however, device and procedural complications, while generally of mild severity, were common.

Project description:Levodopa-carbidopa intestinal gel (LCIG) has shown to be efficacious in motor and non-motor symptoms (NMS). Nevertheless, studies with patient Quality of Life (QoL) as a primary endpoint are scarce. To assess the effect of LCIG on Advanced Parkinson's Disease (APD) patients QoL. Secondarily, the impact on motor symptoms and NMS, emotional well-being, treatment satisfaction, and caregiver QoL, stress, disease burden, anxiety, depression, and work impairment were also investigated. In this prospective, 6-month multicenter postmarketing observational study, LCIG was administered to 59 patients with APD. Endpoints were assessed using validated scales and questionnaires. LCIG significantly improved patient QoL (PDQ-39 mean change ± standard deviation from baseline, -12.8 ± 14.6; P < 0.0001), motor symptoms (UPDRS-III in "On," -6.5 ± 11.8; P = 0.0002), NMS (NMSS, -35.7 ± 31.1; P < 0.0001), mood (Norris/Bond-Lader VAS, -6.6 ± 21.1; P = 0.0297), fatigue (PFS-16, -0.6 ± 1.0; P = 0.0003), depression (BDI-II, -5.1 ± 9.4; P = 0.0002), anxiety (BAI, -6.2 ± 9.6; P < 0.0001), and patient treatment satisfaction (SATMED-Q, 16.1 ± 16.8; P < 0.0001). There were significant correlations between the change from baseline to 6 months between PDQ-39 and UPDRS-IV, NMSS, BAI, BDI-II, AS, and PFS-16 scores, and Norris/Bond-Lader alertness/sedation factor. Caregiver anxiety also improved (Goldberg anxiety scale, -1.1 ± 1.0; P = 0.0234), but the clinical relevance of this finding is questionable. The serious adverse events reported were similar to those previously described for LCIG. In patients with APD, LCIG improves QoL, motor symptoms and NMS, emotional well-being, and satisfaction with the treatment. Improvement in patient QoL is associated with improvements in motor complications, NMS, anxiety, depression, apathy and fatigue. Improvements in patients' QoL does not correspond with improvements in caregivers' QoL or burden.

Project description:BackgroundLevodopa-carbidopa intestinal gel (LCIG) improves motor and non-motor symptoms in patients with advanced Parkinson's disease (aPD).ObjectiveTo present the final 36-month efficacy and safety results from DUOGLOBE (DUOdopa/Duopa in Patients with Advanced Parkinson's Disease - a GLobal OBservational Study Evaluating Long-Term Effectiveness; NCT02611713).MethodsDUOGLOBE was an international, prospective, long-term, real-world, observational study of patients with aPD initiating LCIG in routine clinical care. The primary endpoint was change in patient-reported "Off" time to Month 36. Safety was assessed by monitoring serious adverse events (SAEs).ResultsSignificant improvements in "Off" time were maintained over 3 years (mean [SD]: -3.3 hours [3.7]; p < 0.001). There were significant improvements to Month 36 in total scores of the Unified Dyskinesia Rating Scale (-5.9 [23.7]; p = 0.044), Non-Motor Symptoms Scale (-14.3 [40.5]; p = 0.002), Parkinson's Disease Sleep Scale-2 (-5.8 [12.9]; p < 0.001), and Epworth Sleepiness Scale (-1.8 [6.0]; p = 0.008). Health-related quality of life and caregiver burden significantly improved through Months 24 and 30, respectively (Month 24, 8-item Parkinson's Disease Questionnaire Summary Index, -6.0 [22.5]; p = 0.006; Month 30, Modified Caregiver Strain Index, -2.3 [7.6]; p = 0.026). Safety was consistent with the well-established LCIG profile (SAEs: 54.9% of patients; discontinuations: 54.4%; discontinuations due to an adverse event: 27.2%). Of 106 study discontinuations, 32 patients (30.2%) continued LCIG outside the study.ConclusionDUOGLOBE demonstrates real-world, long-term, reductions in motor and non-motor symptoms in patients with aPD treated with LCIG.

Project description:BackgroundWhile immediate benefits of levodopa-carbidopa intestinal gel (LCIG) are evident in patients with Parkinson's disease (PD), long-term LCIG effects require further study.ObjectivesWe explored long-term LCIG on motor symptoms, nonmotor symptoms (NMS), and LCIG treatment settings in patients with advanced PD (APD).MethodsData were obtained (medical records and patient visit) from COSMOS, a multinational, retrospective, cross-sectional post-marketing observational study in patients with APD. Patients were stratified into 5 groups based on LCIG treatment duration at the patient visit, from 1-2 to > 5 years LCIG. Between-group differences were assessed for changes from baseline in LCIG settings, motor symptoms, NMS, add-on medications, and safety.ResultsOut of 387 patients, the number of patients per LCIG group was: > 1- ≤ 2 years LCIG (n = 156); > 2- ≤ 3 years LCIG (n = 80); > 3- ≤ 4 years LCIG (n = 61); > 4- ≤ 5 years LCIG (n = 30); > 5 years LCIG (n = 60). Baseline values were similar; data reported are changes from the baseline. There were reductions in "off" time, dyskinesia duration, and severity across LCIG groups. Prevalence, severity, and frequency of many individual motor symptoms and some NMS were reduced amongst all LCIG groups, with few differences between groups. Doses for LCIG, LEDD and LEDD for add-on medications were similar across groups both at LCIG initiation and patient visit. Adverse events were similar across all LCIG groups and consistent with the established safety profile of LCIG.ConclusionsLCIG may provide sustained, long-term symptom control, while potentially avoiding increases in add-on medication dosages.Trial registrationClinicalTrials.gov Identifier: NCT03362879.

Project description:BackgroundIn the advanced stages of Parkinson's disease (APD), complex forms of dyskinesia may severely impair the patient's quality of life.ObjectiveIn the present study, we aimed to analyze the evolution under LCIG therapy of the most important motor fluctuations and complex disabling dyskinesias, including diphasic dyskinesia.MethodsIn this retrospective study, we analyzed the characteristics of patients with APD who had at least 30 min of diphasic dyskinesia (DID) in 3 consecutive days, were considered responders and were treated with LCIG in our clinic. Patients were evaluated before and after PEG and at 6, 12 and 18 months, when the changes in the therapy were recorded, and they completed a 7-point Global Patient Impression of Improvement (PGI-I) scale.ResultsForty patients fulfilled the inclusion criteria-out of which, 34 performed all visits. There was a substantial difference between the calculated and real LCIG (1232 ± 337 mg vs. 1823 ± 728 mg). The motor fluctuations and most dyskinesias improved significantly after starting LCIG, but an increasing number of patients needed longer daily administrations of LCIG (24 instead of 16 h).ConclusionsPatients with APD with complex dyskinesias must be tested in dedicated hospitals, and they need a special therapeutic approach. The properly adapted LCIG treatment regarding the dose and time of administration completed with well-selected add-on medication should offer improvement for patients who want to or can only choose this DAT vs. others.

Project description:AimsLevodopa-carbidopa intestinal gel (LCIG) provides continuous levodopa-carbidopa delivery through intrajejunal infusion. This study characterized the population pharmacokinetics of levodopa following a 16 h jejunal infusion of LCIG or frequent oral administration of levodopa-carbidopa tablets (LC-oral) in subjects with advanced Parkinson's disease (PD).MethodsA non-linear mixed-effects model of levodopa pharmacokinetics was developed using serial plasma concentrations from an LCIG phase 1 study and a phase 3 double-blind, double-dummy study of the efficacy and safety of LCIG compared with LC-oral in advanced PD patients (n = 68 for model development; 45 on LCIG and 23 on LC-oral). The final model was internally evaluated using stochastic simulations and bootstrap and externally evaluated using sparse pharmacokinetic data from 311 subjects treated in a long term safety study of LCIG.ResultsThe final model was a two compartment model with a transit compartment for absorption, first order elimination, bioavailability for LCIG (97%; confidence interval = 95% to 98%) relative to LC-oral, different first order transit absorption rate constants (LCIG = 9.2 h(-1) vs. LC-oral = 2.4 h(-1) ; corresponding mean absorption time of 7 min for LCIG vs. 25 min for LC-oral) and different residual (intra-subject) variability for LCIG (15% proportional error, 0.3 μg ml(-1) additive error) vs. LC-oral (29% proportional error, 0.59 μg ml(-1) additive error). Estimated oral clearance and steady-state volume of distribution for levodopa were 24.8 l h(-1) and 131 l, respectively.ConclusionsLCIG administration results in faster absorption, comparable levodopa bioavailability and significantly reduced intra-subject variability in levodopa concentrations relative to LC-oral administration.
