NCT06453226

Brief Summary

Parkinson's disease (PD) is the second most common neurodegenerative disorder. Currently, a diagnostic test for early PD does not exist. The aim to address this problem by developing a non-invasive breath test to differentiate early PD from controls. Small molecules contained in breath, which offers precious information about disease presence, will be analysed. Data from the breath molecules and gut bacterial changes occurring in PD will be combined. These bacterial changes have been shown to arise years before the development of PD symptoms. Thanks to earlier diagnosis, therapies could start in advance and improve clinical outcomes and quality of life.

Outcome Measures

Primary Outcomes (1)

  • Identification of biomarker and measurement of their levels for the development of a non-invasive breath test for Parkinson's diagnosis

    The primary outcome is the identification of biomarkers and measurement of their levels in breath for the future development of a non-invasive breath test, able to diagnose Parkinson's disease. These levels will be measured using gas chromatography mass spectrometry. Differences will be identified in Parkinson's group vs de-novo and healthy controls and important compounds will be therefore identified.

Secondary Outcomes (1)

  • Characterisation of microbiome in Parkinson patients, de novo and healthy controls

    June 2025

Study Arms (3)

Parkinson's group

Patients with confirmed Parkinson's disease undergoing neurological examination

Healthy Controls

Patients will be asked to nominate a partner/carer that can be enrolled in the control group. Healthy controls will also be recruited using web-based adverts mainly via the Imperial Clinical Research Facility and Parkinson's disease charities.

De-Novo

Patients undergoing neurological examination for suspected Parkinson's disease due to presence of symptoms

Eligibility Criteria

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The population for this study will be divided in three groups: (i) Parkinson patients (ii) healthy controls (iii) de-novo patients.

You may qualify if:

  • (i) Patients undergoing neurological examination for confirmed or suspected Parkinson's disease
  • (ii) Patients aged ≥18 years and below 90 years of age;
  • (iii) Patients off antibiotic or probiotic therapies for at least the last 4 weeks;
  • (iv) Patients without formal diagnosis of dysbiotic conditions;
  • (v) Patients with capacity.
  • (i) healthy volunteers that may be or not partner or carer of a Parkinson's patient;
  • (ii) Subject aged ≥18 years and below 90 years of age;
  • (iii) Patients off antibiotic or probiotic therapies for at least the last 4 weeks;
  • (iv) Patients without formal diagnosis of dysbiotic conditions;
  • (iiv) Subject with capacity.
