Plain English Summary

Background and study aims
Parkinson’s disease is a common condition particularly affecting older people. Falls are a very frequent complication of the disease affecting 60% of people with Parkinson's every year. As the population ages, the number of people living with Parkinson’s disease and the occurrence of complications will increase. The loss of the chemical dopamine in the brain causes walking in Parkinson's to become slower, unsteady and irregular. People with the condition are therefore at a very high risk of falling. To some extent, people can compensate for these changes by paying more attention to their walking. However, Parkinson's also diminishes memory and thinking ability. This decreases people’s ability to pay attention to their walking, especially when doing something at the same time.

Who can participate?
Cholinesterase inhibitor (ChEis) are drugs that are currently used to treat people with memory problems in Parkinson’s. The effect of these drugs on falls in Parkinson’s has been tested to show that treatment has the potential to almost halve the number of falls.
This trial aims to definitively determine whether cholinesterase inhibitors (ChEi), can prevent falls in Parkinson’s and whether this treatment is cost-effective.

What does the study involve?
600 participants with Parkinson’s disease will be enrolled from hospitals throughout the UK. Participants will be randomly assigned to either receive the drug (ChEi) via a patch or receive a placebo (dummy) treatment via a patch. Neither the researchers nor the participants will know which group they are in. Participants will take the medication for 12 months and record any falls that they experience in diaries.

What are the possible benefits and risks of participating?
There are a few possible benefits of taking part in this trial. If allocated to the group that receives the active medication, walking unsteadiness and/or balance may improve and falls may be less likely, but there is no guarantee. The information we get from this study will improve the treatment of people with Parkinson’s disease in the future.
There are also some risks and discomforts of the trial. The assessments are quite detailed and therefore may cause tiredness and fatigue.
Like all medicines, the treatment can cause side effects, although not everybody gets them. Because the medication is already used to treat memory problems we know a lot about the side effects.
Side effects are experienced more frequently when you start your medicine or increase the dose. In most cases, side effects will gradually disappear.

Where is the study run from?
Bristol Medical School, University of Bristol, UK

When is the study starting and how long is it expected to run for?

Condition

Parkinson's Disease

Intervention

600 participants with Parkinson’s disease will be enrolled from hospitals throughout the UK. Participants will be randomly assigned to either receive the drug (ChEi) via a patch or receive a placebo (dummy) treatment via a patch. Participants are allocated to the two treatment arms using a technique that minimises the differences between the groups but still allocated people randomly. Neither the researchers nor the participants will know which group they are in. Participants will take the medication for 12 months and record any falls that they experience in diaries and through monthly telephone calls.

TRIAL ASSESSMENTS OVERVIEW
At baseline (enrolment) and follow-up (12 months) detailed tests of Parkinson's disease are undertaken to determine what effect the treatment has on the motor and non-motor symptoms of the condition. At monthly intervals between visits participants will complete a diary (detailed below).

BASELINE VISIT (2.5 hours)
Eligibility confirmation (10 minutes)
Consent (15 minutes)
Disease and functional measures (approx 1.5 hours)
1. Questionnaires (optionally can be completed pre-visit) (15 minutes):
1.1 Freezing of gait (New Freezing of Gait questionnaire NFOG-Q)
1.2 Fear of falling (Iconographical Falls Efficacy Scale [ICON-FES])
1.3 Mood (Geriatric Depression Scale [GDS])
1.4 Capability of older people (ICEpop CAPability measure for Older people [ICECAP-O])
1.5 Quality of life (EQ-5D-5L)
2. Sociodemographics, medical and drug history
3. Brief examination: heart rate (+/- electrocardiogram if indicated), blood pressure, height and weight, Movement Disorder Society Unified Parkinson's Disease Scale (MDS-UPDRS) parts 3 and 4, frailty and gait assessment, Short Physical Performance Battery (SPPB).
4. Functional measures:
4.1 Cognition (Montreal Cognitive Assessment [MoCA])
4.2 Swallowing (Swallowing Disturbance Questionnaire [SDQ])

SELF COMPLETION OF MONTHLY DIARY and PHONE CALLS
Falls are recorded in a patient diary which is posted back to the central team on a monthly basis. Participants are telephoned to remind them about the diaries, to identify any side effects that have occurred.
Questionnaire assessments of quality of life and healthcare use are completed in the diary at months 1, 3, 6, 9 and 12 in order to determine whether the treatment, if successful, is also cost-effective.

Primary outcome measure

Fall rate measured using monthly diaries and telephone calls prospectively over 12 months from the day the IMP is commenced. A fall is defined as “unintentionally coming to rest on the ground or other lower surface without overwhelming external force or a major internal event”

Secondary outcome measures

1. Parkinson's Disease markers assessed via the MDS-UPDRS total score in the practically defined ON state and each individual subscale (1-4) measured at baseline and 12months
2. Freezing of gait assessed via the New Freezing Of Gait Questionnaire (NFOGQ) measured at baseline and 12months
3. Frailty and physical performance assessed via Short Physical Performance Battery (SPPB), gait speed and frailty status measured at baseline and 12months
4. Cognition assessed via Montreal Cognitive Assessment (MoCA) measured at baseline and 12months
5. Depression assessed via Geriatric Depression Scale (GDS) measured at baseline and 12months
6. Fear of falling assessed via the Iconographical Fall Efficacy Scale (ICON-FES) measured at baseline and 12months
7. Dysphagia assessed via the Swallowing Disturbance Questionnaire (SDQ) measured at baseline and 12months
8. Participant health-related quality of life assessed via the EuroQoL 5D-5L health status questionnaire (EQ-5D-5L) measured at baseline, 1 month, 3 months, 6 months, 9 months and 12months
9.Capability of older people assessed via the ICEpop CAPability measure for Older people (ICECAP-O) measured at baseline and 12 months
10. Mortality (all cause and PD related) through Office of National Statistics measured at 12months
11. Cost-effectiveness and NHS resource use through EQ-5D-5L and NHS Episode Statistics (HES) data
