Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The aim of this study is to explore the potential of Ursodeoxycholic acid (UDCA) to slow down the progression of Parkinson's Disease (PD) in a randomised, double-blind, placebo-controlled, "proof of concept" study. The primary objective of the study will be to determine the safety and tolerability of this drug in patients with PD. Participants will be recruited form a cohort of patients who have been diagnosed with PD within the last 3 years and are potentially suitable for this study.
There is strong evidence from previous research and the work carried out by other groups that UDCA rescues the function of the mitochondria (mitochondria are the "powerhouse" of the cell) in PD patient tissue and other models of PD. This suggests that UDCA may slow down the worsening of PD.
UDCA has been in clinical use for the treatment of liver disease (primary biliary cholangitis) for over 30 years. The investigators therefore know that it is safe and well tolerated in patients with liver disease but the investigators don't know yet whether this is also the case in patients with PD. Furthermore, the dose used for patients with liver disease (15 mg/kg) is not high enough for UDCA to get into the brain. The investigators therefore need to double the dose to 30 mg/kg. This higher dose was also safe in clinical trials for liver disease, but is currently not used routinely in clinical practice.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary aim of this study is to generate clinical data to examine the safety, tolerability \& potential effectiveness of 48 weeks exposure to UDCA compared to placebo. Furthermore, it will determine the usefulness of novel objective readouts (namely the objective sensor based quantification of motor progression \& 31P-MRS/imaging-based in vivo quantification of ATP) which may allow a reduction of the sample size (\& thus cost) of future trials.
This is double-blind, randomised, placebo-controlled multi-centre parallel group trial in patients with PD who have been diagnosed ≤ 3 years ago. 30 patients will be randomised to UDCA at a dose of 30 mg/kg or matched placebo using a 2:1 split (20 patients on UDCA, 10 on placebo). This will include 48 week exposure period \& a subsequent 8 week washout period. Detailed evaluations of all patients will take place at Screening, Baseline, 12, 24, 36, 48 \& 56 weeks. The trial medication will be taken at 3 equal doses per day, to be taken orally with food. The dose will be increased gradually by 250 mg (1 capsule) every 3 days until patient reaches a dose of 30 mg/kg.
Visit Schedule
Telephone Contact 1 (Telephone Screening)
Subsequent to the site staff having received a reply slip from the patient indicating their interest to participate in the study, a suitable time \& date will be arranged with the respective patient to undergo telephone screening by a member of the research team to check potential eligibility, including a brief review of relevant medical history. The Chief Investigator (CI)/ Principal Investigator (PI) will check the screening record made after the telephone screening call. Any patients not deemed eligible to be invited for their screening visit will be contacted by a member of the research team to inform them of this outcome. Patients deemed eligible will be invited to a screening visit. The date of diagnosis \& confirmation of the PD diagnosis \& any other uncertainties relating to the inclusion/exclusion criteria will be confirmed subsequent to this telephone screening assessment for those patients who seem eligible but are outside the Sheffield Teaching Hospitals (STH)/ University College London Hospitals (UCLH) geographical area by requesting copies of relevant clinic letters or contacting their PD Clinical Consultants directly. The telephone screening call will be repeated if the patient cannot attend visit 0 (screening visit) within 1-8 weeks to ensure that s/he would still fulfil the telephone screening eligibility criteria.
The telephone screening call will not be undertaken for study patients who are already patients of either site.
Visit 0: Screening (Time -1 - 8 weeks prior to baseline visit)
At this visit the research team will answer any further questions, check the patient's eligibility for the study as far as possible and, if the patient wishes to participate in the study, obtain written consent. A clinical diagnosis of PD is based on the opinion of the Principal Investigator (PI) after review of the patient's clinical history, examination findings \& response to PD medication.
The written informed consent process will be undertaken by the PI or by an appropriately trained member of the research team as delegated by the PI/ CI. This study will not include vulnerable patients or patients who lack capacity.
Screening procedures
The PI (or authorised delegate) will complete the following screening assessments/procedures with the patient:
* Obtaining consent
* Inclusion/Exclusion Review
* Demographic information \& medical history
* Demographic data regarding PD
* Past medical history
* Medication History
* Family history
* Previous imaging
* Previous genetic tests
* Confirmation of eligibility
* Confirmation of date for diagnosis of Parkinson's disease by PIs or other experts in movement disorders (this may include review of medical records)
* Concomitant medication
* Physical examination (including assessment of modified Hoehn \& Yahr stage), including weight, height \&vital signs
* Montreal Cognitive Assessment (MoCA)
* Montgomery-Asberg Depression rating scale (MADRS)
* Confirmation of post-menopausal state
* Safety bloods (full blood count, urea \& electrolytes, liver function tests, blood glucose, HbA1C, lipid profile)
* Serum sample (approach. 20 ml stored at -80 degrees Celsius)
* ECG
* Provision of physical activity monitor \& activity diary
Assuming that the patient fulfils the immediate eligibility criteria, arrangements will be made for the patient to attend a baseline appointment approximately 2 to 4 weeks after the screening visit. This interval enables review of the patient's blood results to confirm final eligibility. If more than 8 weeks have elapsed since the screening visit, the screening visit \& screening assessments should be repeated before proceeding to the baseline visit.
Patients who consent to the study but who are subsequently found not to meet the study eligibility criteria will be contacted by the research nurse or other member of the research team to inform them that they are not eligible to join the study. If any concerns about the patient's health or well-being are identified from out-of-range blood results or abnormal assessment scores, a member of the research team will inform the patient's General Practitioner (GP).
Following written consent, randomisation will take place at the baseline visit. All patients will be assigned a unique patient ID number at screening that will link all of the clinical information collected for them on the study database, these will be in the format Sxx/nnnn; where xx is a unique number assigned to the site by the Trial Manager \& nnnn is a unique number starting at 0001 \&incrementing by 1. Once the patient ID number has been entered, the system will supply a randomisation number which will identify the treatment pack to be dispensed. The randomisation will be 2:1 in favour of UDCA. The randomization system will stratify by site.
Site Study Teams
The local PI, supported by an appropriate member of the research team will monitor patient well-being, record adverse events, titrate \&prescribe study medication. Since the 'treating' nurse or doctor will review all blood results \& be aware of any reported side effects, a separate member of the research team will act as a blinded assessor, undertaking the MDS-UPDRS \& other outcome measures after appropriate training. Ideally the blinded assessor will undertake the MDS-UPDRS Part 3 with the patient in the "OFF" state, followed by the complete MDS-UPDRS, Non-Motor Symptom assessment Scale (NMS-Quest) \& MADRS once the patient is in the "ON" state. The practically defined "OFF" medication state refers to the patient assessment conducted in the absence of their regular medication with the aim of exposing the severity of the underlying PD. Efforts should be made to ensure that the same outcome assessor is present at all visits but sites should identify back-up personnel to cover staff absences \& avoid cross-over of 'assessing' \&'treating' team members.
Baseline (Visit 1)
Eligible patients will attend a further clinic visit where baseline assessments will be performed. Results of blood tests \& ECG will be reviewed prior to baseline evaluation to ensure patient eligibility. They will be asked to attend in the "practically defined OFF" state. The following assessment will be undertaken in the "practically defined OFF" state:
* Confirmation of eligibility/inclusion/exclusion review
* Medication review
* Physical examination
* Recording of any Adverse Events (AEs)
* MDS-UPDRS part 3 (motor examination)
* Optogait \&Opals sensor-based objective quantification of motor impairment (Sheffield Patients only)
They will be invited to take their PD medication following the assessment. The PI or authorised delegate will record any reported serious adverse events \& changes to concomitant medications, including PD medication. In addition, the predicted progression will be calculated, following the model developed by Williams-Gray \& co-workers. The Prognostic Model developed by Williams-Gray \&co-workers identified the following three parameters as associated with more rapid PD progression: 1. Higher age, 2. Higher UPDRS motor examination axial score (items 27-30), 3. Lower animal naming fluency (patients will be asked to name as many animals as possible in a 1-minute time frame). The assessor will then complete the following procedures with the patient in the "practically defined ON" stage (typically 30-60 min after patient has taken PD symptomatic medication):
* MDS-UPDRS
* NMS-Quest
* PDQ-39
* 31P- MRS
* Blood sample for genetic analysis
* Safety bloods
* Serum sample
* Provision of patient diary
* Return of physical activity monitor \&activity diary
Patients will be randomised at this visit to receive either active of placebo medication (2:1 ratio). The PI or appropriately delegated medically qualified member of the study team will complete \&sign a study-specific prescription form for presentation to pharmacy by the patient. The prescription form will details the baseline medication allocation print-out from the randomisation computer system.
All patients will be provided with a study-specific diary by their local research team at the baseline visit, in which to record any alterations in the dose of trial medication or concomitant medications taken. Patients should be advised to contact the study team promptly should they develop loose stools rather than waiting for the next study visit or scheduled telephone call.
Visit 2: 12 week follow-up clinic
Patients will attend a clinic visit twelve weeks after the baseline visit, having taken all medications as usual. The PI or authorised delegate will complete the following procedures with the patient in conjunction with study diary review:

* MDS-UPDRS
* NMS-Quest
* MoCA
* MADRS
* PDQ-39
* Diary review
* Diary collection
For all visits, each procedure is undertaken as part of the study \& not part of the patient's standard care.
Telephone contacts There will be 12 telephone contacts throughout the study, weekly after the baseline visit during the dose escalation period \&week 8, week 18, week 30, week 42 \& week 52. Patients will also be contacted via the telephone 2 days prior to their baseline visit, visit 5 \& visit 6 to remind patients to attend their next visit in the "practically defined OFF medication state" for their next visit.
Sensors At the screening visit, eligible patients will be given the DynaPort Movemonitor to wear for 7 days. A text message will be sent to the patients every morning to remind them to wear the device. A 2nd DynaPort Movemonitor will be posted to patients 2 weeks prior to their 48 week visit with instructions to wear the sensor for 7 days prior to their next visit. Patients will then be asked to return this at their 48 week visit.
This is double-blind, randomised, placebo-controlled multi-centre parallel group trial in patients with PD who have been diagnosed ≤ 3 years ago. 30 patients will be randomised to UDCA at a dose of 30 mg/kg or matched placebo using a 2:1 split (20 patients on UDCA, 10 on placebo). This will include 48 week exposure period \& a subsequent 8 week washout period. Detailed evaluations of all patients will take place at Screening, Baseline, 12, 24, 36, 48 \& 56 weeks. The trial medication will be taken at 3 equal doses per day, to be taken orally with food.
