About this study

Official title: Simvastatin as a Neuroprotective Treatment for Parkinson's Disease: a Double-blind, Randomised, Placebo Controlled Futility Study in Patients of Moderate Severity.

Participants are randomly allocated to one of two treatment groups. In one group, participants are given capsules of simvastatin to take orally (by mouth) for 24 months. In the other group, participants are given placebo (dummy) capsules to take orally for 24 months. At the start of the study, when they receive their medication, participants complete a number of questionnaires and motor (movement) tests (a walking test and a finger tapping test). Participants in both groups also attend a further 6 clinic visits after 1, 6, 12, 18 and 24 and 26 months, where they are asked about their health and any medication they are taking, as well as repeating the questionnaires and motor tests. For 4 of the clinic visits, the participants will be asked to attend in the 'OFF medication' state (having omitted their usual PD medication) so that the researchers can get a true picture of their disease without it being masked by their normal medication.

What is being measured

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

  1. Change in MDS-UPDRS part III (OFF) score

    The MDS-UPDRS is the standard validated tool for the assessment of patients with Parkinson's Disease. This scale includes subsections collecting data regarding the impact of PD on a patient's mood and mental state, (UPDRS part I), their activities of daily living (UPDRS part II) an examination of the motor features of PD (UPDRS part III), and complications arising from the use of dopamine replacement (part IV).

    Measured: Baseline and 24 Months

Secondary outcomes (13)
  1. MDS-UPDRS total score in the practically defined ON state

    Measured: at 12 and 24 months

  2. MDS-UPDRS part II subscale score in the practically defined ON state

    Measured: at 12 and 24 months

  3. Timed motor tests - finger tapping and timed walk test (10MWT) in the OFF state, electromagnetic sensor (EMS) assessment in the OFF and ON state

    Timed Motor Tests include evaluating the number of hand taps (key strokes) that an individual can perform within 30 seconds and a timed walk test (10MWT). Electromagnetic Sensor Measurements include wearing sensors on the index finger and thumb whilst performing 4 MDS-UPDRS items.

    Measured: at 12 and 24 months

  4. Montgomery and Asberg Depression Rating Scale (MADRS)

    The Montgomery and Asberg Depression Rating Scale (MADRS) is a 10 item physician rated depression severity scale previously used in the assessment of PD

    Measured: at 12 and 24 months

  5. The Addenbrooke's Cognitive Assessment-III (ACE-III)

    The Addenbrooke's Cognitive Examination-III (ACE) is one of the most popular and PD STAT protocol version 2.2, 03 March 2016 EudraCT 2015-000148-40 ISRCTN16108482. REC Ref:15/NE/0324 Page 39 of 43 commonly used cognitive tests used in dementia clinics and in the assessment of other neurological disorders. ACE-III includes five subdomains which provide a cognitive score out of a maximum of 100

    Measured: at 12 and 24 months

  6. Non-Motor Symptom assessment scale (NMSS)

    The Non-Motor Symptom assessment scale (NMSS) is a rating scale designed to capture the presence of the non-motor features of PD

    Measured: at 12 and 24 months

  7. Parkinson's disease Questionnaire (PDQ-39)

    The PDQ39 is a PD-specific health status questionnaire used both clinically and within research since its publication in 1995. It consists of 39 items covering eight discrete dimensions: mobility, emotional well-being, stigma, social support, cognition, communication and bodily discomfort. The scores from each dimension are computed into a scale ranging from 0 (best, i.e. no problem at all) to 100 (worst, i.e. maximum level of problem). In addition a summary score, the PDQ-39SI (summary index) can be calculated by averaging the scores of the eight dimensions.

    Measured: at 12 and 24 months

  8. Changes in PD medication as measured by levodopa-equivalent dose (LED)

    Measured: at 12 and 24 months

  9. Cholesterol levels (total, HDL, total/HDL ratio)

    Measured: at 12 and 24 months

  10. King's PD pain scale (KPPS)

    The King's PD Pain Scale is a PD-specific scale consisting of 14 items within seven domains. Each item is scored by severity (0-3) multiplied by frequency (0-4), resulting in an item sub-score of 0-12 and a total possible score of 0-168.

    Measured: at 12 and 24 months

  11. EuroQoL 5D-5L health status questionnaire (EQ-5D-5L)

    Measured: at 12 and 24 months

  12. Safety and tolerability of trial medication by adverse events (AEs) review.

    Measured: at 12 and 24 months

  13. Incidence of diabetes mellitus, using a glycated haemoglobin (HbA1c) level of 6.5% (48mmol/mol) as diagnostic of diabetes mellitus.

    Measured: at 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Simvastatin in people with Parkinson Disease, run by University Hospital Plymouth NHS Trust at 24 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in MDS-UPDRS part III (OFF) score (time frame: Baseline and 24 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02787590, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Oct 2021.
