Clinical Trial Summary

The primary objective of this study was to demonstrate the superiority of levodopa - carbidopa intestinal gel over treatment with optimized oral levodopa/carbidopa during 12 weeks.


Description:

Study S187.3.001 (NCT00357994) and Study S187.3.002 (NCT00660387) were 2 identically designed, Phase 3, 12-week, randomized, double-blind, double-dummy, parallel-group, multicenter studies recruiting subjects from distinct sites. These studies evaluated the efficacy, safety, and tolerability of levodopa-carbidopa intestinal gel (LCIG) in the treatment of levodopa-responsive subjects with advanced PD who had persistent severe motor fluctuations, despite optimized treatment with oral levodopa-carbidopa, concomitant with other available antiparkinsonian medications. Participants were randomized to either LCIG active gel + placebo capsules or levodopa-carbidopa immediate release (IR) active capsules + placebo gel. Both treatment arms received the percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) procedure for gel administration, active LCIG or placebo gel. Data from these 2 studies were combined for analysis. The decision to combine the study data for analysis was made before enrollment was completed for both studies.

Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline to Week 12 in Average Daily Normalized "Off" Time Based on the Parkinson's Disease Symptom Diary. "On" time is when PD symptoms are well controlled by the drug. "Off" time is when PD symptoms are not adequately controlled by the drug. The diary is completed every 30 minutes for the full 24 hours of each of 3 days prior to selected clinic visits. It reflects both time awake and time asleep. Daily totals are normalized to a 16-hour scale (i.e. 16 hours of awake time). The normalized totals for the 3 days prior to the visit are averaged for the analysis. Negative change from baseline for "off" time indicates improvement. Baseline, Week 12 No
Secondary Change From Baseline in Average Daily Normalized "On" Time Without Troublesome Dyskinesia at Week 12 Based on the Parkinson's Disease Symptom Diary. "On" time is when PD symptoms are well controlled by the drug. "Off" time is when PD symptoms are not adequately controlled by the drug. "On" time without troublesome dyskinesia (involuntary muscle movement) is defined as "on" time without dyskinesia and "on" time with non-troublesome dyskinesia. The diary is completed every 30 minutes for the full 24 hours of each of 3 days prior to selected clinic visits. It reflects both time awake and time asleep. Daily totals are normalized to a 16-hour scale (i.e. 16 hours of awake time). The normalized totals for the 3 days prior to the visit are averaged for the analysis. Positive change from Baseline for "on" time without troublesome dyskinesia indicates improvement. Baseline, Week 12 No
Secondary Change From Baseline in Parkinson's Disease Questionnaire (PDQ-39) Summary Index at Week 12 The PDQ-39 is a self-administered questionnaire which comprises 39 items addressing 8 domains of health in Parkinson's disease patients. These include: mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort. The PDQ-39 Summary Index is the sum of all answers divided by the highest score possible (i.e. number of answers multiplied by 4) which is multiplied by 100 to put the score on a 0-100 scale. Higher scores are associated with more severe symptoms. Baseline, Week 12 No
Secondary Clinical Global Impression - Status (CGI-S) Score at Baseline and Clinical Global Impression - Improvement (CGI-I) Score at Week 12 The CGI-S is a global assessment by the Investigator of current symptomatology and impact of illness on functioning. The ratings of the CGI-S are as follows: 1 = normal, 2 = borderline ill, 3 = mildly ill, 4 = moderately ill, 5 = markedly ill, 6 = severely ill, and 7 = among the most extremely ill. The CGI-I is a global assessment by the Investigator of the change in clinical status since the start of treatment. The CGI-I ratings are as follows: 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, 7 = very much worse. Baseline, Week 12 No
Secondary Change From Baseline in Unified Parkinson's Disease Rating Scale (UPDRS) Part II Score at Week 12 The UPDRS is an Investigator-used rating tool to follow the longitudinal course of Parkinson's disease. The Part II score is the sum of the answers to the 13 questions that comprise Part II, each of which are measured on a 5-point scale (0-4). The Part II score ranges from 0-52 and higher scores are associated with more disability. Baseline, Week 12 No
Secondary Change From Baseline in UPDRS Part III Score at Week 12 The UPDRS is an Investigator-used rating tool to follow the longitudinal course of Parkinson's disease. The Part III score is the sum of the 27 answers provided to the 14 Part III questions, each of which are measured on a 5-point scale (0-4). The Part III score ranges from 0-108 and higher scores are associated with more disability. Baseline, Week 12 No
Secondary Change From Baseline in EuroQual Quality of Life - 5 Dimensions (EQ-5D) Summary Index at Week 12 The EQ-5D is a participant answered questionnaire scoring 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. EQ-5D health states, defined by the EQ-5D descriptive system, are converted into a single summary index by applying a formula that essentially attaches values (also called QOL weights or QOL utilities) to each of the levels in each dimension. EQ-5D Summary Index values range from -0.11 to 1.00 with positive change indicating improvement. Baseline, Week 12 No
Secondary Change From Baseline in Zarit Burden Interview (ZBI) Total Score at Week 12 The ZBI is a 22-item questionnaire regarding the caregiver/subject relationship and evaluates the caregiver's health condition, psychological well-being, finances and social life. Each question is answered on a 5-point scale (0=Never, 1=Rarely, 2=Sometimes, 3=Quite frequently, and 4= Nearly always). The caregiver burden is evaluated by the total score (Range 0 to 88) obtained from the sum of the answers to the 22 questions. Higher scores are associated with a higher level of burden for the caregiver. Baseline, Week 12 No
Secondary Change From Baseline in Average Daily Normalized "On" Time With Troublesome Dyskinesia at Week 12 Based on the Parkinson's Disease Symptom Diary. "On" time is when PD symptoms are well controlled by the drug. "Off" time is when PD symptoms are not adequately controlled by the drug. The diary is completed every 30 minutes for the full 24 hours of each of 3 days prior to selected clinic visits. It reflects both time awake and time asleep. Daily totals are normalized to a 16-hour scale (i.e. 16 hours of awake time). The normalized totals for the 3 days prior to the visit are averaged for the analysis. Baseline, Week 12 No
Secondary Change From Baseline in Parkinson's Disease Questionnaire (PDQ-39) Mobility Domain Score at Week 12 The PDQ-39 is a self-administered questionnaire which comprises 39 items addressing 8 domains of health in Parkinson's disease patients. The PDQ-39 Domain: Mobility (e.g., fear of falling when walking) includes 10 questions, each answered on a 5-point scale. The domain scores are calculated by first summing the answers to the questions in the domain. The sum is divided by the highest score possible (i.e., number of answers multiplied by 4) and the quotient is multiplied by 100 to put the score on a scale from 0 to 100, where lower scores indicate a better perceived health status. Higher scores are consistently associated with the more severe symptoms of the disease such as tremor and stiffness. Baseline, Week 12 No
