About this study

Official title: COSMOS - COmedication Study Assessing Mono- and cOmbination Therapy With Levodopa-carbidopa inteStinal Gel

The purpose of this study is to evaluate treatment of advanced Parkinson's Disease (PD) patients on levodopa-carbidopa intestinal gel (LCIG) monotherapy in a routine clinical setting.

Read the detailed description

Participants with advanced Parkinson's Disease who have been prescribed LCIG for at least 12 months will be entered into the study cohort. Clinical data will be collected by retrospective review of the participant's medical records as well as a single study visit for current data. Treatment of the participants and follow up will be according to the physician's judgment, regional regulations and the product monograph.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants on Levodopa-Carbidopa Intestinal Gel (LCIG) Monotherapy From LCIG Initiation to 12 Months

    The percentage of participants on LCIG monotherapy from immediately following LCIG initiation to 12 months. LCIG monotherapy means that the participant is not on any add-on Parkinson's (PD) medication/PD therapy at the respective time point (monotherapy 1) or that the participant is allowed to take an add-on PD medication/PD therapy at the respective time point but only in the evening after the LCIG infusion is completed (monotherapy 2).

    Measured: 12 months

Secondary outcomes (12)
  1. Percentage of Participants Starting Add-On PD Medication Within 12 Months of LCIG Monotherapy Initiation

    LCIG monotherapy means that the participant is not on any add-on PD medication/PD therapy at the respective time point (monotherapy 1) or that the participant is allowed to take an add-on PD medication/PD therapy at the respective time point but only in the evening after the LCIG infusion is completed (monotherapy 2). PD medications were captured by time point and category from the initiation of LCIG therapy until the introduction of each add-on PD medication taken. Categories included levodopa, catechol-O-methyltransferase (COMT) inhibitors,dopamine agonist (excluding apomorphine), monoamine oxidase (MAO) inhibitor, n-methyl-d-aspartate receptor (NMDA) antagonist, apomorphine, anticholinergics, surgical therapy, or other. Participants may have initiated more than one PD medication or category.

    Measured: 12 months

  2. Total Daily Dose (in Milliliters) of LCIG Infusion at 12 Months After LCIG Initiation

    Physicians were asked to document the LCIG infusion details at 12 months after LCIG initiation, including the total daily dose. Total dose per day was calculated as morning dose + continuous dose x duration of infusion + extra dose. Abbreviations: ml = milliliters.

    Measured: 12 months

  3. Healthcare Resource Utilization (HCRU): Primary Occupation by Number of Participants

    The HCRU questionnaire is used to assess healthcare resource utilization. Participants were asked about their occupational status (primary occupation), caregiver support (change in amount of caregiver help needed with daily activities/home care), and participant´s opinion on Parkinson's disease medication (number of pills in addition to LCIG the participant was willing to take each day).

    Physicians were asked to report details regarding participant visits and hospital admissions in the 12 months prior to the study visit.

    Measured: 12 months

  4. HCRU: Caregiver Support by Number of Participants

    The HCRU questionnaire is used to assess healthcare resource utilization. Participants were asked about their occupational status (primary occupation), caregiver support (change in amount of caregiver help needed with daily activities/home care), and participant´s opinion on Parkinson's disease medication (number of pills in addition to LCIG the participant was willing to take each day).

    Physicians were asked to report details regarding participant visits and hospital admissions in the 12 months prior to the study visit.

    Measured: 12 months

  5. Percentage of Physicians With Overall Preference for LCIG Monotherapy

    The overall preference for treatment using LCIG as monotherapy compared with LCIG plus add-on PD medication, as stated by the physician.

    Measured: 12 months

  6. Predictors for Monotherapy (Participant Data): Forward Selection for Monotherapy 1 (12 Months After LCIG Initiation)

    LCIG monotherapy 1 means that the participant is not on any add-on Parkinson's (PD) medication/PD therapy at the respective time point. The influence of predefined variables was evaluated using multivariable logistic regression models. The target variables were analyzed using two different sets of potential predictors: one set containing participant data and one set containing site and physician data.

    Measured: 12 months

  7. Predictors for Monotherapy (Physician Data): Forward Selection for Monotherapy 1 (12 Months After LCIG Initiation)

    LCIG monotherapy 1 means that the participant is not on any add-on Parkinson's (PD) medication/PD therapy at the respective time point. The influence of predefined variables was evaluated using multivariable logistic regression models. The target variables were analyzed using two different sets of potential predictors: one set containing participant data and one set containing site and physician data.

    Physician data in table shown as "average frequency of routine visits" includes average frequency of routine visits for advanced Parkinson's disease (APD) participants on device aided therapy ≥3x/years.

    Measured: 12 months

  8. Duration (Days) of LCIG Monotherapy 1 or Monotherapy 2

    LCIG monotherapy means that the participant is not on any add-on PD medication/PD therapy at the respective time point (monotherapy 1) or that the participant is allowed to take an add-on PD medication/PD therapy at the respective time point but only in the evening after the LCIG infusion is completed (monotherapy 2). Duration of LCIG monotherapy was calculated for all participants who reached the respective monotherapy as time from LCIG initiation until LCIG is given as a monotherapy (separately for monotherapy 1 and monotherapy 2 definition).

    Measured: 12 months

  9. Time (Days) From Initial LCIG Administration to Substantial Dose Adjustments by Country

    Time for substantial change was determined as the time from LCIG initiation until the first substantial dose change in days 12 months after LCIG initiation. A substantial change was defined as a change of at least 20% compared to the LCIG dose at LCIG initiation.

    Measured: 12 months

  10. Time (Days) From Initial LCIG Administration to Substantial Dose Adjustment

    Time for substantial change was determined as the time from LCIG initiation until the first substantial dose change in days 12 months after LCIG initiation. A substantial change was defined as a change of at least 20% compared to the LCIG dose at LCIG initiation.

    Measured: 12 months

  11. Days From Initial LCIG Administration to the Initiation of LCIG Monotherapy

    Time (in days) from LCIG initiation until monotherapy was calculated for those participants who were not on monotherapy (i.e., needed additional PD medication during LCIG infusion) at LCIG initiation, but reached monotherapy during the study. LCIG monotherapy means that the participant is not on any add-on PD medication/PD therapy at the respective time point (monotherapy 1) or that the participant is allowed to take an add-on PD medication/PD therapy at the respective time point but only in the evening after the LCIG infusion is completed (monotherapy 2).

    Measured: 12 months

  12. Tapering Duration (Days) From Initial LCIG Administration of Each PD Medication

    LCIG monotherapy means that the participant is not on any add-on PD medication/PD therapy at the respective time point (monotherapy 1). The number of days for tapering process is the number of days between maximum and minimum daily dose; participants with minimum (or maximum, respectively) daily dose not at the end of the tapering process were checked. A maximum duration of approximately 2 months of the tapering process was allowed (otherwise the tapering process was set to missing).

    Measured: 12 months
