Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 90 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: All potential participants need to have to capacity to give consent prior to study enrolment. Study participation is not possible if the participant is unable to give consent or does not have the capacity to consent.

Who may be able to join

  • -Inclusion criteria for patients:
  • For Parkinson's patients and early-onset Parkinson's:
  • Diagnosis of Parkinson's disease, based on UK Brain Bank criteria and made within the preceding 3 years ('recent onset cases'); or
  • diagnosed at under 50 years ('under 50 years cases')
  • For clinical symptoms suspicious for a diagnosis of PD but clinical uncertainty with regard to a definite diagnosis:
  • clinical symptoms not meeting all of the required UK Brain Bank diagnostic criteria for the diagnosis of PD; or
Show all 11Show fewer
  • clinical features not typically associated with PD and therefore raising the possibility of a different type disorder/movement disorder referred for a DaTSCAN as part of the National Health Service (NHS) clinical diagnostic work-up to investigate a suspicion for a parkinsonian movement disorder-type disease, or referred for a research DaTSCAN as part of existing N3iPD and PaMIR studies for the diagnostic work-up to investigate a suspicion for a parkinsonian movement disorder-type disease.
  • Age ≥18 to <90years
  • Being able and willing to provide informed consent
  • Age ≥18 to <90years
  • Being able and willing to provide informed consent

Who cannot join

  • The patient has severe comorbid illness that would prevent full study participation
  • The patient has features indicating another type of degenerative parkinsonism, e.g. progressive supranuclear palsy
  • Drug-induced parkinsonism (Drug-unmasked PD is allowed)
  • Symmetrical lower body parkinsonism attributable to significant cortical and/or subcortical cerebrovascular disease (patients with 'incidental' small vessel disease on brain imaging are allowed).
  • Negative or normal functional imaging of the presynaptic dopamine system
  • The presence of UK Brain Bank exclusion criteria will be recorded at baseline, allowing for the presence of 1 or 2 exclusion criteria (e.g. dopamine antagonist Drug used; more than one affected relative) (if justified e.g. by abnormal SPECT).
Show all 14Show fewer
  • Any contraindication to Magnetic Resonance (MR) scanning.
  • Any major neurological (other than PD), psychiatric or cardiovascular disease or history of brain injury.
  • Medical illness or medication that may affect brain morphometry or function.
  • Patient who is pregnant and/or breastfeeding.
  • Subject has severe comorbid illness that would prevent study participation
  • Subject already has a diagnosis of Parkinson's disease
  • Any contraindication to Magnetic Resonance (MR) scanning
  • Subject who is pregnant and/or breastfeeding.

About this study

Official title: In Vivo Serial Neuromelanin MRI to Assess Depigmentation Rates in the Substantia Nigra of Early Parkinson's Disease

Prospective observational study to qualify NM-MRI as progression marker in early Parkinson's.

Read the detailed description

Parkinson's is the second most common neurodegenerative disorder with progressive, disabling motor and non- motor symptoms for which effective symptomatic, but non disease-modifying treatment is available. Neuromelanin- containing neurons in the substantia nigra undergo neurodegeneration during Parkinson's disease. There is considerable heterogeneity in the progression of cell loss and clinical symptoms with major research interest in identifying prognostic subtypes.

A non-invasive biomarker that can track the loss of the neuromelanin-containing neurons would be highly desirable to (i) study subtype-specific trajectories of SN depigmentation, (ii) track disease progression in early Parkinson's to assist in stratifying groups and outcome assessment in clinical intervention trials, and (iii) enable patients and their families to better manage their condition including informed forward planning. Neuromelanin MRI (NM-MRI) is a new approach sensitive to the neuromelanin-iron complex, with proven association with the tissue changes of the number of the neuromelanin-containing neurons. Its diagnostic value was established in several studies case-control, but there is a lack of standardisation, multi-centre studies and prospective diagnostic trials. To date only a small, single arm retrospective study reported serial NM loss in Parkinson's.

Building on our previous work, the proposed research entails the development of an early progression biomarker for Parkinson's disease that is pathologically relevant, non-invasive, and uses MRI which is a widely available imaging method for detection. The experimental approach combines advanced computational imaging, retrospective use and extension of existing cohorts with a new dedicated prospective serial study using NM-MRI in uncertain parkinsonism, de novo and early Parkinson and healthy controls using latest MRI technology.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MRIDiagnostic test

    Also called Blood test, Physical examination

    The clinical examination includes a short physical exam, a brief history of allergies, previous diseases and medications, and disease-related questionnaires.

    All the participants will undergo 4 serial MRI scans: one MRI scan at the baseline visit, 6, 12, 18 months follow-up visit, respectively to record the changes in the brain, which include the neuromelanin scan.

    For future proving the value of our study, we will also collect and store blood samples at the initial visit.

What is being measured

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

  1. Neuromelanin signal in PD

    The primary outcome measure of this study is the neuromelanin-related signal on dedicated 3T MRI.

    Measured: 6 months

Secondary outcomes (1)
  1. Depigmentation rates

    • differences in depigmentation rates between Parkinson's and controls in extended retrospective cohorts (discovery)
    • to assess whether earlier depigmentation rates can predict longer term clinical change based on commonly used outcome markers in clinical trials

    Measured: 2 years

Individual data sharing
Yes: A new high-quality neuromelanin MRI database with linked whole brain multimodal MRI, clinical findings and stored blood samples. We intend to quality control and curate the imaging and clinical data for the generation of a data repository, and have included cost for data storage, but ultimately intend to integrate this into the Critical Pathway Initiative. Where possible. We also aim to release imaging-derived parameters to make the data usable for non-imaging communities.
