Study population

Adult participants with advanced Parkinson's disease have discontinued treatment with foslevodopa-foscarbidopa and are receiving LECIGON® as part of their routine care will be included in this observational study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult participants (18 years old and over) with advanced Parkinson's disease with severe motor fluctuations and dyskinesia
  • Participants for whom the treating physician has made the decision to initiate treatment with LECIGON® in accordance with the Summary of Product Characteristics (SmPC)
  • Participants must have had previous treatment with subcutaneous foslevodopa (foslevodopa-foscarbidopa) for a minimum of 1 month
  • Participants or legal representative must have signed to participate in the study

Exclusion criteria

Exclusion Criteria:

  • Participants with as defined in the current version of the SmPC for LECIGON®
  • Participants who will not be seen again for their follow up care at the investigator's site after commencement of LECIGON® therapy
  • Participants with anticipated pump placement or pump use issues, e.g. participants with acute severe illness, participants unable to perform pump therapy, and in case of lacking compliance due to severe dementia, agitation or alcohol abuse
  • Participants taking part in a clinical (interventional) trial at the same time
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Change from Baseline in the Reduction in OFF time (h/day) as Measured by Movement Disorder Society-unified Parkinson's Disease Rating Scale, Part IV (MDS-UPDRS IV) at 12 months

    The MDS-UPDRS is a revision of the Unified Parkinson's disease rating scale (UPDRS) developed to evaluate various aspects of Parkinson's disease including non-motor and motor experiences of daily living and motor complications. Part IV concerns motor complication and all questions in Part IV that deal with motor fluctuations and dyskinesias, the investigator is required to conduct the interview of participants.

    Time frame: Baseline, Month 12

Secondary outcomes

  1. Change from Baseline in the Reduction in OFF time (h/day) as Measured by MDS-UPDRS IV at 6 months

    The MDS-UPDRS is a revision of the UPDRS developed to evaluate various aspects of Parkinson's disease including non-motor and motor experiences of daily living and motor complications. Part IV concerns motor complication and all questions in Part IV that deal with motor fluctuations and dyskinesias, the investigator is required to conduct the interview of participants.

    Time frame: Baseline, Month 6

  2. Change from Baseline in the Reduction in OFF time (h/day) as Measured by Hauser Patient Diaries

    The Hauser Diary is a home diary, completed by the participant, that assesses functional status in participants with Parkinson's disease with motor fluctuations and dyskinesia. Participants will complete the Hauser Diary for a 72-hour period occurring after informed consent has been obtained and prior to LECIGON® treatment start and for 48 hours prior to each of the two follow-up visits.

    Time frame: Baseline, Months 6 and 12

  3. Change from Baseline in LECIGON® Treatment Patterns due to Change in Daily Levodopa Dose (mg/day) as Measured by Total Daily Dose Using Multi-rate Programming of Pump

    Total daily levodopa dose will be measured using the multi-rate programming of pump.

    Time frame: Baseline, Months 6 and 12

  4. Change from Baseline in Clinical Global Impression of Improvement as Measured by Clinical Global Impression of Change (CGI-C)

    Time frame: Baseline, Months 6 and 12

  5. Change from Baseline in Clinical Global Impression of Improvement as Measured by Patient Global Impression of Change (PGI-C) at 12 months

    Time frame: Baseline, Months 6 and 12

  6. Change from Baseline in Non-motor Experiences of Daily Living as Measured by MDS-UPDRS-I

    The MDS-UPDRS is a revision of the UPDRS developed to evaluate various aspects of Parkinson's disease including non-motor and motor experiences of daily living and motor complications. Part I concerns non-motor experiences of daily living. Several questions from Part I are designed to be amenable to a patient/caregiver questionnaire format and therefore can be completed without the investigator's input. For the remaining Part I questions that deal with complex behaviors, the investigator is required to conduct the interview of participants.

    Time frame: Baseline, Months 6 and 12

  7. Change from Baseline in Motor Complications as Measured by MDS-UPDRS-IV

    The MDS-UPDRS is a revision of the UPDRS developed to evaluate various aspects of Parkinson's disease including non-motor and motor experiences of daily living and motor complications. Part IV concerns motor complication and all questions in Part IV that deal with motor fluctuations and dyskinesias, the investigator is required to conduct the interview of participants.

    Time frame: Baseline, Months 6 and 12

  8. Change from Baseline in Quality of Life as Measured by Parkinson's Disease Questionnaire Total Score (PDQ-8)

    The PDQ-8 is an eight-question instrument, completed by the participants, that measures the quality of life among Parkinson's disease participants. It is a shortened version of the 39-item Parkinson's disease questionnaire to reduce participant burden and increase convenience for use among Parkinson's disease participants. It includes one question from each of the dimensions including include mobility, activities of daily of living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort.

    Time frame: Baseline, Months 6 and 12

  9. Change from Baseline in Sleep as Measured by Parkinson's Disease Sleep Scale - 2 (PDSS-2)

    The PDSS is a visual analogue scale, completed by the Parkinson's disease participant, addressing 15 commonly reported symptoms associated with sleep disturbances, including overall quality of night's sleep, sleep onset and maintenance insomnia, nocturnal restlessness, nocturnal psychosis, nocturia, nocturnal motor symptoms, sleep refreshment, and daytime dozing. The PDSS-2 uses a 5-point frequency scale (0-4) for each item, with a total score ranging from 0 to 60. Higher scores indicate more severe sleep problems.

    Time frame: Baseline, Months 6 and 12

  10. Treatment Satisfaction Questionnaire at Months 6 and 12

    Participants will be asked questions to assess their satisfaction with LECIGON® treatment.

    Time frame: At Months 6 and 12

  11. Change from Baseline in Body Mass Index (BMI)

    Time frame: Baseline, Months 6 and 12

  12. Number of Participants With Adverse Drug Reactions (ADRs), Serious ADRs, Reportable Events (REs), Serious REs and REs of Special Interest (RESIs)

    An ADR is any untoward and unintended response to a medicinal product, related to any dose administered and which implies a RE with at least a reasonable possibility of a causal relationship with the use of the product. A RE is any unfavorable or unintended sign, symptom or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. RESIs include drug interaction, drug exposure during pregnancy, drug exposure during breastfeeding, lack of drug efficacy, overdose, misuse/abuse, medication errors (incl. prescription and application errors), off-label use, adverse reaction which occurred during occupational exposure, falsified medicinal product, suspected transmission of infectious agents via a medicinal product.

    Time frame: 12 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
